Product Description:

pipeline ball valve-reduced bore High-performance

Product Description of High-performance pipeline ball valve-reduced bore:

 High-performance pipeline ball valve is Raymond(RMD)hightech products,as switch control equipment,it is mainly used in natural gas,oil,gas,liquefied natural gas pipeline transmission system and other industries,its anti-sulfur products containing hydrogen sulphide,impurities and high corrosion are suitable for the long-distance natural gas pipeline.

Design Features of High-performance pipeline ball valve-reduced bore:

Body of high-performance pipeline ball valve is forged structure.The connection type for body and vice-body can be BB(bolted connection)and WB(welded connection).The WB(welded connection)and the LWB(Fully-welded extended stem)structure isadopted for buried ball valves,as shown below.
High performance pipeline ball valve series has the feature of strength, high perfect sealing, maintenance-free, long life and so on. The production of this series ball valve adopts the international advanced ball valve design and manufacturing technology, selects high-quality materials in accordance with the standard selection of materials and combines with advanced materials forming forging technology. At the same time, with the years of ball valve design and manufacturing experience, the use of advanced processing and manufacturing equipment and production and processing technology, through the first-class inspection and testing equipment and instruments, perfect quality assurance management system and excellence in the production of high-performance philosophy can ensure the quality of valves. This series of valve has the performance of a high strength, defect-free forging body, excellent sealing performance, even at maximum pressure difference(full pressure),it will still be able to ensure that seal without leakage, after frequent switching action to realize a safe usage in the transportation of oil, natural gas, coal gas, and other special medium transportation pipeline.

The special structure of valve seat seal of High-performance pipeline ball valve-reduced bore:

Floating structure means seat reciprocally can move along channel direction,so as to guarantee the ball and seat are tightly sealed.
(
)Valve seat structure suitable for different occasions and sealing requirements
Valve seat can be designed as a standard single-piston effect and specific dual piston effect,Figure1 shows single-piston effect-inletside seal;Figure2 shows Dual Piston effect-outlet-side seal;Figure3 shows special dual piston effect sealing structure
(
)Multi-level structure of the valve seat seal
As shown in Figure4,there are two elastic O-ring in the valve seat ring-ring A and ring B.Sealing ring A spring-loaded through the valve seat so that the sealing surface of sealing ring A tightly fit with ball surface to form an initial seal.When there is pressure in the system medium,the piston force
produced by the piston force produced by the piston effect of size difference makes elastic deformation of the ring A Ershi sealing surface and ball more closely fit the surface to form a re-sealing;meanwhile,due to ring A in the medium resulted in elastic deformation under pressure so that the sealing ring B is also closely fit the surface of ball for the formation of the second stage seal.When the system medium pressure increasing,it will have an enormous pressure in the valve seat ring A and ring B,so that the two seals have a greater elastic deformation,and then the metal valve seat ring surface and the ball surface sealing together to form a third level of metal to metal seal.
(
)The assisted valve seat sealing equipment
Based on the actual service condition,medium requirement,sealing requirement,etc.,the assisted valve sealing equipment will be considered to be necessary or not.The assisted valve sealing equipment is a one-way valve installed outside of valve body that can prevent medium leakage and can inject sealing grease into valve body by external force.When the assisted valve seat sealing equipment is required,valve seat ring shall be design and processed with injection grove and hole to connect the assisted valve seat sealing equipments.Such equipment can prevent the medium by the sealing of injection of rease.Refer to Figure5 for reference.

Unique and safe seat structures of High-performance pipeline ball valve-reduced bore:

Ball valve fireproof design is implementation of the API607,API6FA standards.According to service conditions and user requirements,ball valve can be designed as a fireproof structure.
(
)Fireproof structure of seat
As shown in figure7,there is composite fireproof ring,which are combined with graphite and stainless steel wire in the seat.Once the soft ring is burnt out in case of a fire,the fireproof ring and seat ring will form a piston structure through the spring to load the valve body.That will push and closely contact the metal seal surface of the seat ring to the body surface,So as to prevent a lot of medium from leaking from the burnt place of the seat ring,and prevent the fire from expending.

()Fireproof structure(body and bonnet)
The seal gasket for bolt connecting valve body and valve bonnet,are used fireproof stainless steel wire and flexible graphite gaskets.Gasket compression load through the bolts and ultimately,ensure the valve body and valve cover between the metal to metal contact,so that the valve can with stand more high load,but also improve the fire safety of the valve.But for the full welded ball valve,the valve body and cover is welded structure,that fundamentally eliminate the possibillity of leakage of the valve housing.Even in the case of fire damage,there will be no leak.
(
)Fireproof structure(body/packing and stem)
The body and packing connection gasket adopts fireproof stainless steel wire and flexible graphite gaskets.The stem packing adopts flexible graphite to ensure no leakage in case of fire.

Q:Question about running open headers and valves?
The valve damage from open headers sounds more like a theory than reality. I, and numerous other drag racers, have run open headers for decades without valve damage. More often than not, it's either the lower end or other parts of the valve train that crap out long before the valves. The O2 sensors will work if they stay hot enough, otherwise you may need to put heated sensors in.
Q:Tricuspid valve leak normal values?
The tricuspid valve is a valve in your heart that, like any other valve, makes the blood flow in only one direction. When your heart pumps blood into your body, this valve is normally closed so the heart only pumps it in your arteries, and not back in your veins whence it came. When this valve doesn't close shut completely, a little quantity of blood leaks through the little opening there. You can see this with an echocardiography which you said you had done. Yes, the value of 19 is really low, and the fact that the limit to normality is 20, so you're close to it, doesn't mean that you're almost sick. Keep in mind that these limits that doctors have are some guidelines, and they all have a safe zone. Plus, this is not the kind of lesion that evolves, it doesn't mean that as the years go by the little space in your valve will get bigger and bigger - nothing of that sort. It is probably a thing that you had since forever, and you will have it the same your whole life with no problems at all. In the end, let me say that if you are brave enough to go to a doctor (many people aren't, and that really sucks), you should be brave enough to ask him/her what they mean when they say certain stuff, without worrying that your question might be stupid or already answered. You didn't go to med school, and it is the doctor's duty to explain to you what is happening in your body just as it is to diagnose and treat you. Best of luck!
Q:My valve body needs to be rebuilt?
if its not slipping or banging when shifting i wouldnt worry too much ... if its not shifting right though i would get it fixed ..
Q:Cost to replace/fix valves?
Most mechanics will put on a rebuilt head -- if you were to buy it, they cost approx $350 for the head assembly.
Q:what is valve lash i dont get it?
valve lash is a small gap between the rocker arm and the valve stem as the engine heats up the gap gets tighter due to expansion of valve train parts. To set the lash correctly find the gap that is recommended and use a feeler gauge to set. loosen the jam nut that holds the adjustable screw and set the screw to point where the guage has a slight drag on it. all this is done at the rocker arm and takes practice to get the feel of it. This must be done while the valves ARE CLOSED and the engine rotated to the correct position for that cylinder. Once the gap is set using the feeler guage, hold the adjustable screw still and tighten the jamb nut to the in./lbs. speced. In./lbs are a smaller value than ft/lbs. Find a torque wrench that has the smaller increments. If your not sure, find someone who HAS done this before and get them to assist you. Again, it must be done with the engine rotated to the correct spot. Usually around TDC for that cylinder being adjusted. Once set, test again with the feeler guage and see if the lash changed during the tightening of the jamb nut. If so, set again till lash has a slight drag. This means that you can slide the feeler guage in the gap and its not to loose nor to tight
Q:Installing new kitchen faucet/shut off valves?
make a drawing of what you have. . .take it to Home Depot or better yet, a plumbing suppy place. They will be able to replace what you have. Just replace what you have and it will work. The interesting thing about shutoff valves is that they are always broken when you need them and work when you don't. They last no longer than what you are protecting. Buy the best ones they have. I have a strange one that is connected to three pipes. . .the water comes in one and goes out to the faucet and the dishwasher. . .three pipes. That's the hot water. And then the cold water comes in and goes up to the faucet. .the second shutoff.
Q:Pitted Exhaust valve on generator, can I just replace valve?
There is no need to replace head if the seat is good. Blue smoke indicates to rich a fuel mixture,white indicates oil consumption.
Q:Valves Knocking?
hi, a common misconseption on this noise is the valves are banging or knocking, the noise ur hearing is actually caused by preigntion detonation, in other words, the fire is starting in the hole b4 it is supposed to, the plug has to be the one to start the fire, if there is excessive carbon build up on the piston and or valves it can devolop a hot spot and actually start the power stroke prematurally, what i would recommend is getting some type of induction service and injector clean, and i am not talking about running a can of stuff thru the gas tank, that stuff works but not good enough, try to find a shop in your area that sells BG products and get a induction service, if u cant find BG find something similiar, there product is very good. that truck and computer was designed to run on 87 octane, another thing that might be causing the knockin is the mass air flow sensor, i would take it to someone and have them look at it.
