The main structure of 815 & 830 series butterfly valve follows wafer amd flanged three-eccentric structure, but 815 & 830L series butterfly valve consist of body round with lugs and the desgin of single flange with bolting holes. 815 & 830 series buttferfly valve is widely applicable to petroleum, chemical industry, environmental protection water treatment, high building, water supplying and drain pipelines, and so on.
For the three-eccentric stucture, reliable sealing ability, it assure not to contact the seat when the disc is in open position and eliminate uneven load of the seats, extend the usage lifetime, and also assure the reliable sealing ability with high temperature resistant, friction resistant, corrosion resistant, etc.

- Q:How do hydraulic butterfly valves work?
- 3. butterfly valve hydraulic drive device structureThe valve hydraulic device is mounted on the valve drive shaft. The driving shaft of the valve is fixed with a transmission spline, and the crank (with an outer spline) is sleeved on the driving shaft. When the hydraulic system works normally, through the gear sleeve, the transmission spline is connected with the crank. Thus, the hydraulic cylinder drives the crank, and the spline on the crank passes the torque to the transmission spline by means of a gear sleeve. Because the driving spline is fixed on the driving shaft, the driving shaft rotates and drives the valve plate to start and close. A section of optical axis is arranged at the end of the driving shaft and is inserted into the end of the manual shaft (matched with the clearance of H11/ H11), and the function is that the manual shaft is concentric with the main drive shaft. In normal operation, the optical axis rotates with the drive shaft, but the manual device does not move. When the hydraulic operation is performed manually or manually from the hydraulic unit, a * * * conversion is required. The utility model is composed of a nut, a hand wheel, a screw rod, a support frame and a shifting device. When the utility model is switched, the hand wheel is rotated and driven by the screw rod to move. A guide rod is arranged on the bracket to make the shift and translation stable.
- Q:The difference between butterfly valve d71x_10s and d341s-10
- Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.
- Q:Butterfly valve structure and working principle
- Butterfly valve structure: Center to clip butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve, three eccentric butterfly valve
- Q:Hi guys, i asked a question before pertaining to the amount of cylinders and asking if it meant V4 or V6 or whatever.I actually meant to say VALVES, not cylinders. IS there a direct correlation between VALVES and Clyinders..Eg, My car, which is a 2001 Neon LE states right on the engine block quot;16 VALVEquot; in bright letters. I am sure this is a 4 cylinder engine. I haven't had a car that broadcasted the number of VALVES before. Another car I had broadcast that is was a 3.3 Liter V6 right on the engine.Is there a mathematical relationship between VALVES and cylinders, or would my car be braodcasting 16 VALVES, because a 4 cylinder doesn't typically HAVE 16 valves, or what is the story??Recently, I was looking at an altima, and it said 24 valves. Can you tell just by the number of valves if it is a 4 cylinder or 6 cylinder or whatever??Thanks.
- Well a lot of valves signify that more air/gas is getting to the engine so it suggests a more powerful engine. So your car has 4 valves per cylinder. Now that's pretty much a standard number so most expensive cars don't really even talk about that. They mostly just advertise the displacement. You can't really tell the type of engine via the number of valves because it does vary by manufacturer. For example there could be a 16 valve V8 also also(2 valves per cylinder). There are some ratios that dont work like a 16 valve V6 because you cannot have 2.6 valves.
- Q:Butterfly valve general use occasions
- Valve is especially suitable for low differential pressure, large diameter, large flow of gas and slurry liquid. For general control valve, DN300mm is big valve, only individual to DN450, and for the butterfly valve, DN500 below is a small valve, DN500 ~ 1000 is the standard valve, the largest butterfly caliber up to 9m. Visible, large diameter pipe with the main butterfly valve.
- Q:What is the butterfly valve
- Double valve technology is the use of large sets of small valve valve technology, place a small butterfly in the large butterfly valve, when feeding in a large number of double valves open at the same time, the material quickly added, when the material is in accordance with the set to a certain number, the valve automatically shut down, by a small valve to feed, until it reaches the requirements of the control system the number of closed, so as to ensure high precision batching material, thereby saving expensive raw materials.
- Q:i was changing valve seals and two dropped i can see the head of the valve but a magnet wont pull them up i put air the spark plug hole too but no luck 1985 ford bronco II
- The valve head is larger then the valve port, so it's not coming out of there. Pull the head.
- Q:How warm is the PTFE butterfly valve?
- PTFE butterfly valve, sealing surface of fluorine plastic, temperature -29 ~ 450 degrees
- Q:What is the difference between turbine butterfly valve and flanged butterfly valve?
- Their models are different, the structure is different, they are the main driving part, different worm gear and straight rod distinguish, all belong to the flange valve.
- Q:How to calculate the size of the manual butterfly valve?
- [1] type code, transmission mode, connection form, structure form, sealing surface material or lining material, nominal pressure, valve body material, this is the most basic arrangement way now D341X-16C. [2]: butterfly valve also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the air water, steam, and all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.
