Q:What's the size of the check sleeve?
According to the valve connection mode (thread connection, flange connection), select valve rating, modify the valve name
Q:What's the difference between the check valve and the stop valve?
Check valve is also called check valve or one-way valve, single-phase closed, individual hydraulic control one-way valve, plug valve also has a combination of controllable changes.The cut-off valve has the possibility of variable flow, two-way action, throttling possible, there can be two-way closed applications.
Q:The difference between swing check valve and lift check valve
Swing check valve, swing check the valve to the disc valve seat around the channel axis for rotation, because the valve channel into a streamlined, flow resistance than the small valve lift check, suitable for large caliber occasions in low flow and no flow frequently change, but should not be used for the pulsating flow, the sealing performance is less than lift. Swing check valve is divided into single, double, and most types of three, the three forms mainly by the valve bore points, the purpose is to prevent the media to stop flow or reverse flow, weakening the hydraulic impact.
Q:The difference between check valve and check valve
One way valve is also called a check valve, the two is the same kind of valve, meaning the same.
Q:Is it necessary to install a check valve for household well pumping?
Selection of check valve for pump outlet check valveGeneral pump station project, for the pump outlet check valve, the following principles should be observed;The outlet check valve shall be used when the diameter of the outlet pipe of the pump is smaller, that is, DN50mm.The pipeline of the pump outlet pipe diameter DN is larger than 50mm, should be used in swing check valves can be installed horizontally or vertically. Swing check valve to rotate around the shaft, the fluid resistance is generally less than the lift check valve, which applies to the larger diameter of the occasion, the installation location restrictions, usually installed in horizontal pipelines, it applies with large caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves for medium and medium duty applications. Large diameter pipeline using single swing check valve, in order to reduce the water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double valve swing check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a fast check valve. Multi disc swing check valve is suitable for large diameter pipeline
Q:Check valve can not stop water, how to solve?
Valve is broken, change one, my family is like this
Q:How much pressure is the check valve h47x-10q?
Check valve h47x-10q is 1.0MPa pressureAccording to the provisions of the JB/T 308-2004 valve type programming method:H== check valve4== connection: flange7== structure: butterfly typeX== sealing surface material: Rubber10== pressure rating: 1.0MPaQ== body material: ductile iron
Q:What's the difference between a throttle valve and a check valve? Are they the same?
The principle is very simple, just like upstairs said, like a revolving door, this is the swing test. There are lifting type, it is unknown.And "throttling" is to reduce the pressure of the fluid. In the pipeline, the fluid through the throttle valve, through the hand wheel or other transmission way to adjust the size of the internal channel, so that the flow of fluid flow down, to save traffic flow.
Q:Is the overcurrent valve a check valve?
The overflow valve is just a pipe overflow pronounSuch as decompression, flow valve, butterfly valve, flow valve and so onActually, they are all called in the front wordsTherefore, can not be replaced to illustrate
Q:The working principle and structure description of the mute check valve
1, when the medium according to the provisions of the direction of flow, the valve by the media force, is open; the medium back, due to weight and disc valve by the medium reverse force, so that the sealing surface of the valve flap and valve seat sealing and closed, to prevent the media counter to.2, the body and valve sealing surface using stainless steel surfacing.3, the length of the valve according to the provisions of GB12221-1989, flange connection size according to the provisions of JB/T79-1994.
