Q: Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?: Stop valve: a valve that closes the valve and moves along the center line of the valve seat. According to this form of valve movement, the valve seat opening change is proportional to the valve stroke. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation. Therefore, this type of valve is very cooperative for cutting or regulating and throttling.Advantages: in the process of opening and closing, because the friction between the valve and the sealing surface of the valve body is smaller than that of the gate valve, the utility model has the advantages of wear resistance. Second, the opening height is generally only 1/4 of the seat channel; therefore, it is much smaller than the gate valve; usually there is only one sealing surface on the valve body and the disc; therefore, the manufacturing process is better and the service is easy to maintain. Because its packing is generally a mixture of asbestos and graphite, it has a higher temperature resistance. Steam valves are normally used with stop valves.Disadvantages: as a result of the medium through the valve flow direction has changed, so the minimum flow resistance valve is higher than most other types of valves; second, due to longer travel, opening slower than the ball.

Q: Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?: Because of the unsteady flow of fluid near the inlet and outlet of the valve, the measured data cannot be obtained relatively accurately.

Q: How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.: Flanges for piping above DN50,DN50 (below) can be made of wire or flange (flange for pressure piping)

Q: What is the meaning of socket welding gate valve A105, D&S:STLT, STEM:13Cr, CL800, SW, AP1602, BB-BG-OS&Y?: Body material: A105Sealing surface material: STLStem material: 13CrPressure rating: CL800Connection: SWImplementation criteria: AP1602BB-BG-OS&Y: plain rod support, bolt connection, flange valve cap.

Q: Why the valve can only be fully open and fully closed valve can adjust the flow?: Gate valve, stop valve are switching type valve, adjust the flow can not talk about, can only do so called throttle.You say "stop valve" or "translation" problem, in English, globe valve and valve word is often the same.

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's the meaning of the gate valve model z41x 16Q?: Gate valve (Z) flange connection (4) wedge type single gate (1) rubber soft seal (X) -16 pressure) (Q)

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: What is wire feed gate valve? What do you say in French?: Point to the wire gate valve. Refers to the valve body with internal thread or external thread, and pipe thread connection. Also called thread valves, threaded valves, valves within the toothFlange gate valve is connected to the flange gate valve, this connection is the most common wayThe main difference is the connection

Q: What does "Z45W-10T" mean?What does each letter stand for?: W is the seal material or lining material code, the valve sealing material is the valve body material, the valve sealing surface material code with "W" said, here stands for brass;The 10 is the pressure code, which stands for PN10, which is often called 1.0MPa;
