Q:Gate valve DN65 what does that mean?
Nominal diameter 65 gate valve.This depends on the material of your valve, it is new material, it is to use the outer diameter to do the standard, specifications with 63.75, and so on, because the new material is welded or coated with glue connection. So use the outside diameter as the standard, or the gap will appear.There is also the metal standard, according to the nominal diameter, or flange connection flange and skein skein are industry specifications.When it comes to the end, it must be between the pipe and fittings must be connected.
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:Function of signal butterfly valve and gate valve
The signal butterfly valve applies to petroleum, chemical, food, medicine, papermaking, water and electricity, ships, water supply and drainage, smelting, energy and other system pipelines. It can be used as regulating and throttling devices in a variety of corrosive, non corrosive gases, liquids, semi fluids, and solid powder pipelines and containers. It is widely used in high buildings, fire protection systems and other piping systems that need to display valve switching status.
Q:Stainless steel gate valve DN150 200300 weight, who knows?
Valve selection of different driving methods, connection forms, structural forms, nominal pressure, sealing surface materials, lining materials, valve body material will affect the weight of the gate valve more or less, it can not be generalized.Take my commonly used Z41H-16P (i.e. PN1.6MPa) series stainless steel gate valve as an example, and the weight of DN150/200/300 is 134/192/379kg. Of course, different manufacturers may vary in weight, but not much.I hope I can help you.
Q:What is the soft seal gate valve?
Cautions for installation and maintenance of soft sealing gate valve:For double gate valves, the direction of installation shall be in the vertical position of the valve stem, and the handwheel at the top.The installation of the soft gate valve shall be carried out in strict accordance with the installation environment, installation conditions and installation procedures on the factory manual.After installation, the soft seal gate shall be periodically checked for performance and killed in the cradle before any undesirable conditions occur.
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 does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
Cast steel flanged gate valve 25 pressure bore 250
Q:Pump adapter generally includes what accessories?
Generally do not require safety valve, just install exhaust valve in individual places.
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 does gate z41t-10 150 mean?
According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150
