- Q: Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?
- Steam traps: in steam, compressed air and other media, there will be some condensation water formation, in order to ensure the efficiency and safety of the device operation, should be timely discharge of these useless and harmful to the media, to ensure the consumption and use of the device. It has the following functions: 1. It can quickly eliminate the condensed water; prevent leakage of steam; remove air and other non condensable gases.Pressure reducing valve: by adjusting the inlet pressure to a certain outlet pressure, and rely on the energy of the medium itself, so that the outlet pressure automatically maintain a stable valve.Check valve: also known as reverse flow valve, check valve, back pressure valve and one-way valve. The valves are automatically driven and closed by the flow of the medium itself, belonging to an automatic valve. The check valve is used for piping system, the main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. It can be divided into swing type (rotating by gravity center) and lifting type (moving along the axis).
- Q: The difference between flanged gate valve and common gate valve
- General diameter of more than 50 with flanges, inspection wells, main pipes, trenches... Must use flange gate valve, good operation, good replacement.
- Q: What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
- Cast steel flanged gate valve 25 pressure bore 250
- 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: 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: 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: What are the structural differences between parallel and wedge valves?
- The structure of globe valve and gate valve. What does this article introduce first?What is parallel gate valve?The sealing cover is parallel to the vertical center line, so the sealing surfaces of the valve body and the gate are parallel to each other. This gate valve is the most common double gate plate, in order to shut down, so that the valve and gate two sealing surface contact closely asked, often used in two ram double sided thrust wedge block. Thus, when the valve is closed, the double side thrust block is contacted with the bottom of the valve body and is gradually stressed.
- Q: Generally, how big is the diameter of the installation flange plate gate valve?
- Under normal circumstances:Flanged gate valves for piping over DN50,DN50 (below) can be made of wire or gate valves, or flanged gate valves (flanged valves or welded gate valves)
- Q: The main question is, what are the functional differences in which case?
- The gate (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 valve. The 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 valve advantages: 1, fluid resistance is small,.2, opening and closing more labor-saving,.3, medium flow unrestricted, not disturbed flow, do not reduce pressure,.4, simple shape, structural length is short, manufacturing process is good, a wide range of applicationsValve shortcomings: 1, between the sealing surface is easy to cause erosion and abrasions, maintenance is more difficult,.2, big size, open need some space, opening and closing time is long,.3, the structure is more complex
- Q: The legend of gate valve and stop valve
- When the valve is installed, the medium can enter from the bottom of the valve core and enter the two way from the top. Medium from the spool into the advantages of the valve closed when the packing is not under pressure, can extend the service life of the packing, and can be pressure in front of the valve in the case of replacement of packing work. Medium from the spool into the bottom of the shortcomings of the valve driving torque is larger, about 1.05~1.08 times above the entrance, the stem by the axial force of large, easy to bend the stem. To this end, the media from below to enter the way, generally only applicable to small caliber manual stop valve, to the valve closed, the media acting on the spool of force is not greater than 350kg limit. Electric cut-off valve is generally used to enter the media from the top way. The disadvantage of the medium entering from the top is just the opposite of the way it is entered below.Compared with the gate valve, the utility model has the advantages of simple structure, good sealing performance, and convenient manufacture and maintenance. The disadvantage is that the liquid resistance is large, and the opening and closing force is large. Gate and globe valves are fully open closed type valve, cut off or connected as the medium use, not as a control valve.The range of application of stop valves and gate valves is determined by their characteristics. In the smaller passages, the cut-off valve is used when required for better shutoff; in the steam pipe and the large diameter water supply pipe, the gate valve is generally used because of less fluid resistance.
