- Q: Role of ball valve DN20-Q11F-16
- Q11F ball valve is to control the circulation and cut-off of the pipeline medium.
- Q: And the cut-off valve is not the general name of gate valve and butterfly valve?What are the signs of differentiation?How about the use?
- When the valve is opened, the opening height of the valve is 25% to 30% of the nominal diameter, the flow has reached the maximum, which means that the valve has reached full open position, so the opening position of the stop valve should be determined by the stroke of the discThe cut-off valve has the following advantages:The utility model has the advantages of simple structure and convenient manufacture and maintenanceSmall travel time, short opening and closing timeGood sealing, friction between the sealing surface of small, long lifeThe disadvantages of the cut-off valve are as follows:The resistance of fluid is large, and the force required for opening and closing is largerNot suitable for medium with particle, viscosity and easy cokingPoor regulation performanceType valve stem according to the position of divided threaded screw type, internal thread. Divided by the flow of media, there are straight through, DC type and angle type. Divided by the form of valve seal, a packing seal bellows seal valves and valve.The installation and maintenance of the cut-off valve shall pay attention to the following matters:The stop valve operated by the handwheel and handle can be installed in any position of the pipeHand wheel, handle and steering mechanism are not allowed to be used for liftingThe flow direction of the medium shall be in accordance with the arrow shown in the valve body
- Q: What are the differences and advantages between O ball valve and V ball valve?
- Quality solutionsO type ball valve with floating or fixed type design, the relative movement of the parts are made of small friction coefficient of self-lubricating material, so the operating torque is small, in addition to the long-term sealing and sealing grease, making the operation more flexible, its advantages are as follows:1, fluid resistance is smallGeneral valve diameter and diameter shrinkage of two kinds of structure, no matter what kind of structure, valve flow resistance coefficient are relatively small. The conventional ball valve for the straight through, also called full flow type ball valve, channel diameter is equal to pipe diameter, friction resistance loss is only the same length of pipe. All valves, this valve fluid minimum resistance. There are two ways to reduce the resistance of pipeline system: one is to reduce fluid flow, is to increase the diameter and the valve diameter, it will greatly increase the cost of the system. The two line is the local resistance reducing valve, ball valve is the best choice.
- Q: To help explain the meaning of the ball valve Q11H-16H, combined with the actual, such valves have wood?
- JB T308-2004 valve model preparation method and "GB1048-2005 pipe element nominal pressure definition and selection", there are various types of valve interpretation:Q11H-16HQ: valve type: (Q) ball valve1: connection form: (1) internal thread1: structure form: (1) through flow channelH: sealing surface or lining material: (H) Cr13 stainless steel16: pressure code: (16) 1.6MPaH: body material: (H) Cr13 stainless steel
- Q: I've seen a lot of hot water projects. Why do most of them use globe valves, and ball valves are seldom used?.Globe valves have those benefits compared to ball valves (because the cut-off valve is more expensive, I think it is more expensive and more useful. It must have some advantages in that respect.)Is the stop valve more durable than the ball valve?What are the specific differences between the two PPR valves?
- Yes, now the globe valve is more than the ball valve with more people, and its main or cut-off valve, a lot of adjustability, and most can be universal.Specific differences are as follows:Valve opening and closing parts are plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. Stem movement in the form of lifting rod (stem lifting, hand wheel not lifting), but also lifting, rotating rod type (hand wheel with the valve stem to rotate up and down, nut on the valve body). Valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.The cut-off valve is a forced seal type valve, so when the valve is closed, the valve must be applied to the pressure, to force the sealing surface is not leaking. When the medium into the valve six from the bottom of the valve, the operating force required to overcome the resistance, is the stem and the packing friction and pressure generated by the media thrust force than the valve off the valve opening force, so the diameter of the valve stem, otherwise it will bend the stem top of the fault. In recent years, the emergence of self sealing valve, globe valve replaced by medium flow on the top of the valve into the valve chamber, then in the medium under pressure, the valve off a small force, and force open the valve, stem diameter can be reduced accordingly. At the same time, in the role of media, this form of valve is also more stringent. China's valve "three to" has stipulated that the flow direction of the cut-off valve should be top-down.
- Q: For example, how many sizes and pressures are used in the two piece?
- A piece of ball valve is mainly manual, two piece ball valve for atmospheric pressure and high pressure, three pieces of ultra high pressure will be used, according to the actual caliber to determine
- Q: What is the difference between ball valve and plug valve?
- Plug valves are closed or plunger shaped rotary valve, through the rotation of 90 degrees to make the valve plug on the mouth of the channel with the valve on the mouth of the same or separated, to achieve a valve opening or closing. Plug valve plug shape can be cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; in the tapered valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve lighter, but at the same time a certain loss. Plug valves are most suitable for cutting and turning on the medium and for shunting applications, but in accordance with the applicable nature and sealing surface erosion resistance, sometimes also used for throttling. As the plug seal between the movement with a wipe action, while fully open, you can completely prevent the contact with the flow medium, it is usually also used for suspension with particles of media. Another important feature of the plug valve, it is easy to adapt to multi-channel structure, so that a valve can get two, three, or even four different flow channels. This simplifies the design of the piping system, reduces the amount of valve used, and some connecting fittings needed in the equipment.Plug valves use:Plug valves are widely used in oil production, transportation and refining equipment, but also widely used in petroleum, chemical, chemical, gas, liquefied petroleum gas, HVAC and general industries.
- Q: The difference between gate valve, ball valve and butterfly valve
- Gate valve: there is a flat plate in the valve body which is perpendicular to the direction of the medium flow, and the plate is lifted and closed.Features: good tightness, fluid resistance small, open and close force is small, widely used, also have to regulate the flow performance, generally applicable to the large diameter of the road.Ball valve: the use of a hole in the middle opening of the ball as the spool, by rotating the ball to control the opening and closing of the hair.Features: the structure is simpler than the gate valve, small size, low fluid resistance, and can replace the role of gate valve.Butterfly valve: closure is a disk-shaped, around a fixed axis rotation of the valve body.The utility model has the advantages of simple structure, small size and light weight, and is suitable for making larger diameter valves. As the sealing structure and materials are still problems, it is only used for low pressure, for the transport of water, air, gas and other media!Own code words, hope to adopt!
- Q: What does "ball valve" Q41F-10P mean?
- Q valve (Qiu represents the first letter of the alphabet), 4 representative flange, second representative is 1 ball valve floating ball (ball valve floating ball and fixed ball, 7 ball, F fixed on behalf of) on behalf of PTFE- PTFE seal (PTFE PTFE), representing 10 of the nominal pressure valve is 10 kg (1.0Mpa), P represents the valve body material is 304 stainless steel.Soft sealing stainless steel flanged ball valve
- Q: What does copper ball valve mean by "1/2"?
- 1/2 is inch inch, which is what is usually called "valve", and the caliber is "DN15". You can see the contrast chart of the valve diameter and inch.
