- Q:The legend of gate valve and stop valve
- Compared with the cut-off valve, the main advantage is that the flow resistance is small, the flow resistance coefficient of ordinary gate valve is about 0.08~0.12, while the ordinary cut-off valve resistance coefficient is about 3.5~4.5. Opening, closing force is small, the medium can flow in two directions. The disadvantage is that the structure is complex and the height is large. The sealing surface is easy to wear. The sealing surface of the valve must be forced to close the valve to achieve sealing, in the same caliber, work pressure and the same drive device, the drive valve torque is 2.5~3.5 times the gate valve. This point should be noticed when adjusting the torque control mechanism of the electric valve.The sealing surface of the stop valve contacts each other only when the valve is completely closed, and the relative sliding amount between the valve core and the sealing surface is very small, so that the wear of the sealing cover is very small. The sealing surface of the valve cover, mostly due to the spool and sealing surface before the debris, or because of the closed state is not tight, causing the medium of high-speed erosion caused by.
- Q:Why does the fire hydrant box in the air defense area need to be added with gate valves?
- when the envelope from the introduction of civil air defense, air defense should be set in the side of retaining structure; through the protection unit between the closed wall, should be installed in the pipe walls on both sides of the door closed;2 protection valve nominal pressure shall not be less than 1.OMPa;
- Q:Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
- 3, soft sealing rubber lining valve plate size uniform, interchangeable. Therefore, the soft sealing gate valve will be the direction of development, but also the water supply industry is willing to adopt a valve.
- Q:What is the soft seal gate valve?
- General soft sealing gate valve model is Z41X Ming bar. The dark pole is Z45X. They're all for hydraulic purposes
- Q:Does the relief valve have a gate valve?
- With the ball valve, needle valve, with the valve did not see, but there should be some.
- Q:What does valve qz45x - 10q mean?
- Crown valve pressWhat does Q stand for? I'm not sure. It's probably made of ductile iron"Z" means "gate valve"4 represents flange connection5 represents the dark bar (1 represents the Ming pole)X stands for rubber seal and soft seal10q stands for 10 pressure
- Q:What type of flange does it fit with the gate valve?
- According to the welding plate flange, flange material selection of piping material.
- Q:What is the meaning of socket welding gate valve A105, D&S:STLT, STEM:13Cr, CL800, SW, AP1602, BB-BG-OS&Y?
- Body material: A105Sealing surface material: STLStem material: 13CrPressure rating: CL800Connection: SWImplementation criteria: AP1602BB-BG-OS&Y: plain rod support, bolt connection, flange valve cap.
- Q:what are their applicable conditions? Advantages and disadvantages?
- Butterfly valve is a disc type of open and close parts reciprocating reciprocating about 90 degrees to open, close and adjust the fluid channel of a valve.Advantages: the butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, and torque is small, simple and rapid operation, and also has good flow characteristics of regulation and sealed off, is nearly 10 years the fastest growing valve, high temperature and high pressure, and to large diameter, high sealing function of the direction, long life, good adjusting features and a valve development.Disadvantages: the butterfly valve relative to the gate, ball valve pressure loss is relatively large, it is suitable for pressure loss requirements lax piping system.Under normal circumstances, it is not suitable for high temperature and high pressure pipeline system.Valve is closed parts (valve) moving along the centerline of the valve seat, the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional to, is also very suitable for the regulation of traffic.Advantages: in the process of opening and closing, the friction between the disc and the valve body is smaller than that of the gate valve, so it is wearableThe opening height is generally only 1/4 of the diameter of the seat channel, so it is much smaller than the gate valveGenerally, there is only one sealing surface on the body and disc, so the manufacturing process is good and easy to maintain;Disadvantages: the flow resistance coefficient is relatively large, resulting in pressure lossUnsuitable for large caliber productionThe opening and closing moment is larger and the structure length is longer.
- Q:Generally, how big is the diameter of the installation flange plate gate valve?
- Under normal circumstances:Flanged gate valves for piping over DN50,DN50 (below) can be made of wire or gate valves, or flanged gate valves (flanged valves or welded gate valves)
