Q:Fire protection gate valve from the wall how many distance there is no regulation?
1 meters away from the wall, leaving the maintenance and replacement distance
Q:What kind of valve is gate valve? Is it different from the cut-off valve?
Gate valve is applied to the big diameter pipeline valve, the valve is generally used in small pipe diameter pipeline, their internal structure is different, the valve can not regulate the flow of water, the valve can be. If you want to understand in detail, it is recommended to take a sample of valve manufacturers to see the internal structure.
Q:What is the wedge type gate valve wedge is what mean
It can be used on high pressure gate valve. Wedge gate and elastic wedge gate, gate and double gate. A, elastic ram. A circular groove is machined on the vertical bisector surface of the gate so that the gate plate has a certain elasticity. It is this elastic deformation, the gate is closed, the compensation gate sealing surface and the valve seat sealing surface between the wedge angle deviation, the arrival of good agreement, to ensure the sealing. Resilient gate valve sealing surface reliable. Applicable to a variety of pressure and temperature of small and medium-sized gate valve, requiring medium containing solid particles to less, in order to prevent congestion in the gate ring groove, affecting the flexibility of sealing.
Q:What is the standard for ductile iron gate valve set?
The valve material name, specifications and price according to the facts that the valve rod input line.
Q:What's the difference between the knife gate valve and the stop valve?
Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure, highly toxic and so on.Stop valve is able to stop and adjust flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!
Q:Which is more expensive, bronze gate valve or brass gate valve?
But the obvious weakness of brass is its poor strength, relatively large volume, and its lack of corrosion resistance.
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 do you mean by forged steel gate valves 800LB DN20 SW?
Forged steel gate 800LB pressure DN20 is by SW said socketweld (connection)
Q:What does gate valve DN200PN160 mean?
