- Q: What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve
- Stop valve and gate valveThe 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 does gate valve Z41H-40 mean?
- Z-- valve, 4-- connection, flange connection, 1-- structure, open bar wedge type rigid single gate valve, surfacing iron hard alloy h-- seal, 40- nominal pressure is 40 kg, which is 4.0MPa, the material is carbon steel casting
- Q: What is the difference between gate valves Z41W-16R and Z41W-16P?
- According to JB/T308P stands for Cr-Ni stainless steelR stands for Cr-Ni-Mo stainless steelCr-Ni stainless acid resistant steel has CF8, CF3, F304, F304L, which applies to the medium of work, such as nitric acid oxidation acid.Cr-Ni-Mo stainless acid resistant steel has CF8M, CF3M, F316 and F316L, which is suitable for working medium, such as acetic acid and reducing acid.
- Q: What are the meaning of the cast rigid gate valves z41h-16c?
- According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== flange connection1== rigid single gateH== sealing surface material: Cr13 stainless steel16== pressure rating: 1.6MPaC== body material: carbon steel
- Q: What is gate well?
- Explanation:Valve wells also called valve wells, underground pipelines and underground pipelines (such as tap water, oil, natural gas pipeline valve etc.) in order to facilitate the opening and closing part of network operation or overhaul when needed, a pit is a similar small room (or well), the valve installation in the pit where, for regular inspection, cleaning and dredging pipeline, to prevent the blockage of the pipeline project. The pit is called a well. There are valves, wells must have valves, but there is not necessarily a valve valve wells.
- 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: Is the axial force and torque of the wedge gate valve the same?
- See where you are, it is better to compare it: wedge type single gate valve features: a structure more flexible, gate valve is simple, sealing performance better than flexible gate valve or double gate valve.
- Q: What is plug welding gate valve?
- Socket welding valve refers to the use of socket welded connection valve.Simple socket welding is to insert the pipe into the gate joint to weld.The form of socket welding is mainly used for welding small bore valves and pipes, fittings and pipes. Small caliber pipeline wall thickness is thin, and error prone edge ablation, butt welding is difficult, more suitable for socket welding. In addition, the socket of socket welding has reinforcement effect, so it is also used under high pressure. But socketweld also has disadvantages, one is the stress condition is not good after welding, easy welding penetration, pipe inside a gap, so should not be used for piping system of crevice corrosion sensitive medium pipeline system and clean high requirements for socket welding. In addition, ultra high pressure pipeline, even small caliber pipe wall thickness is also very big, can use butt welding connection, as far as possible to avoid socket welding.
- Q: Acid resistant alkali valve gate valve
- A products have few connections and good overall steel quality.B closure speed is fast.C opening limit mechanism is convenient, flexible and precise.
- Q: What is the difference between gate valve 41h-16c and 41w-16p?
- According to the provisions of the JB/T 308-2004 valve type programming method:H== sealing surface material: Cr13 stainless steelC== body material: carbon steelW== sealing surface material: body, that is, with the same material bodyP== body material: chrome nickel stainless steel
