- Q: Valve flange drawing n- up to what
- A bolt hole used to indicate a flangeThe value of N indicates the number of bolt holesUp to the numerical representation of bolt hole size
- 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: How to distinguish between gate valve and cut-off valve?
- The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume. 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.
- Q: Gate valve type Z40Y, Z40H letters - what does that mean?
- According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange0== structure: wedge type elastic RAMY== sealing surface material: hard alloyH== sealing surface material: Cr13 stainless steel
- 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 difference between an elastic gate valve and a rigid gate?
- Brief introduction: the valve gate valve is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'.Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.
- Q: What's the difference between a soft seal gate valve and a hard sealed gate valve?
- The difference is that the form of the gate seal surface is different.General gate valves are generally leaking, easy to rust and other phenomena. Soft sealing gate valve (elastic seat sealing gate valve), gate material for cast iron lining rubber, overcome the shortcomings of the general gate valve, such as poor sealing, elastic fatigue, easy to rust, etc.. Soft sealing gate valve is a new product of the traditional gate valve.
- Q: Gate valve is gate valve, gate valve specifications, model code is generally what?
- Valve lock valve and gate valve. According to the code, the domestic valve type standard, valve type valve is composed of valve type, drive mode, valve connection, valve structure, sealing material, body material code to said gate type code Z.Gate valve: gate valve is one of the most commonly used shut-off valve, mainly used to connect or cut off the pipeline medium, not used to regulate the flow of media. A wide range of pressure, temperature and diameter is used, especially for medium and large diameter pipes.1, the main characteristics of gate valve(1) fluid resistance is small. The through hole of the gate body is straight through, and the flow direction of the medium does not change when flowing through the medium, so the flow resistance is smaller.(2) opening and closing is more labor-saving. When opening and closing, the direction of valve plate movement is perpendicular to the direction of flow of medium. Compared with the opening and closing more effort.(3) medium flow direction is generally unrestricted. The medium can flow in any direction from both sides and can achieve the purpose of switching on or cutting off. Easy to install, used in the flow direction of the medium may change in the pipeline.
- 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 a flanged gate valve and a wire gate valve?
- Flanged gate valves are flanged and must be welded to the flanges of the pipe, bolted together
