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 Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
Cast steel flanged gate valve 25 pressure bore 250
Q:The difference between flanged gate valve and common gate valve
General diameter of more than 50 with flanges, inspection wells, main pipes, trenches... Must use flange gate valve, good operation, good replacement.
Q:What are the advantages and disadvantages of flat gate valves?
The disadvantage of flat gate valve is that when the medium pressure is low, the sealing force of the metal sealing surface is insufficient, so as to achieve satisfactory sealing. On the contrary, when the medium pressure is high, if the sealing surface is not lubricated by the system media or foreign media, often opening and closing may cause the sealing surface to wear too much. Another disadvantage is that the circular motion of the circular gate in the circular flow, only when it is at the valve closed position of 50%, this valve is more sensitive to flow control. Moreover, the gate will produce severe vibration when it breaks the high-speed and dense medium flow. The valve seat can also be throttled if the seat is made of a V - shaped opening and is tightly oriented to the gate.
Q:What's the meaning of flexible z45x-10q door valve?
Crown valve pressModel Z45X-10QZ refers to gate valve4 finger flange connection5 refers to the dark bar driveX refers to rubber seals10 refers to 10 kg pressureQ refers to the body material, ductile ironFull bore flange soft sealed gate valve
Q:What are the features and uses of the gate valve?
1) advantages: sealing performance than the cut-off valve, the fluid resistance is small, open and close more effort, full sealing surface by the erosion of media, media flows from the restrictions, with double flow, small structure length, wide application range. 2) disadvantages: high size, open need a certain space, opening and closing time is long, in the opening and closing, the sealing surface is easy to erode and scratch, and the two sealing pairs bring difficulties to the processing and maintenance.3) use: gate valve is generally used in the caliber of DN15-1800mm pipes and equipment, and its dosage is great, mainly cutting off function, not allowed to throttle.
Q:Why does the fire hydrant box in the air defense area need to be added with gate valves?
3, protective valve should be used for stainless steel or copper gate valve or cut-off valve;4, air defense enclosure structure, the distance from the proximal end of the valve should not be greater than 200mm. Valve should have obvious signs of opening and closing.
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:What does P54100V mean in power station gate valve Z960Y-P54100V?!
P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar
Q:Gate valve Z41H-16Q generally used for what place?
Gate valve is one of the most commonly used cut-off valve, mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Suitable for medium and large diameter pipelines.
