Q:The difference between cut-off valve and gate valve
The working principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!Gate valve and stop valve are shut-off valve, is the most common two valves.From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
Q:What is a protective gate valve? What is gate valve knowledge?
Explosion-proof valve products, is a kind of safety valve can eliminate the shock wave which can stop the water hammer shock wave, it is a product composed of multiple sets of safety,
Q:Is the gate valve clockwise or closed?
Usually it's off. There are some special occasions. It is said that the plane uses a lot of counter
Q:What is the wedge type gate valve wedge is what mean
B. wedge type single gate, it is the whole wedge gate. In the process of opening and closing the sealing surface is prone to scratches, easy to make the temperature change gate wedge live. It is a gate used for normal temperature, medium temperature and various pressures. C. wedge double plate, which is composed of two gates composed of spherical top hinged into wedge-shaped gate. The advantage is that the accuracy of the cover angle is lower; the sealing surface of the gate can be compensated by adding shim at the top of the seal; the temperature changes are not easy to cause the phenomenon of the card master, nor should it be abraded. Because the gate is movably connected and has more parts, it is easy to bond in the viscous medium and affects the sealing. Especially when the upper and lower baffles are corroded all the year round, the flashboard falls off arbitrarily. It is usually used for water, steam and gas pipelines.
Q:Soft sealed gate valve and hard sealing gate valve which good?
If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.
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:Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
Water supply and drainage and civil air defense works, now with the dark rod type elastic sealing gate valve more.Compared to the gate and the traditional carve type or parallel double gate plate valve has the following characteristics: 1, soft sealing valve body, valve cover using precision casting foundry, a molding, no mechanical processing, do not use sealed copper ring, saving non-ferrous metals;
Q:What is the difference between Z41X gate valve and Z45X gate valve?
All flange soft sealing gate valve, but 41X is Ming bar, 45X is dark pole
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:What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?
Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.
