- Q:Check valve is 150, why not put 150 of the smoke pipe?
- DN150 check valve, it is possible that the internal path is less than the required value of 5mm-10mm. Therefore, the 150 outer diameter of the smoke pipe is not up.
- Q:What is the difference between the H44H check valve and the H41 check valve?
- The lift type horizontal check valve shall be installed on the horizontal pipeShanghai reliance Valve Manufacturing Co., Ltd.Lifting type is more swing type, good sealing, large resistance to fluid, horizontal should be installed in the horizontal pipe, vertical mounted on the vertical pipe;Swing type check valve installation location is not restricted, it can be installed in horizontal, vertical or inclined pipeline, such as installed in the vertical pipe, the flow direction of medium to bottom up; x0d
- Q:Check valve symbols?
- The valve that prevents the backflow of the medium is called a check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents.
- Q:Can the check valve be horizontally installed?
- Lift check valve can be divided into straight through and vertical two. Straight through lift check valve can only be installed in horizontal pipe, vertical lift check valve is usually installed in vertical pipe.
- Q:How can the check in the faucet prevent water from flowing backwards?
- Not to prevent backflow, is able to quickly shut the water, for triple bathtub, can effectively stop the conversion between the bath and small shower water, there is a spring, when the water pressure will be water, a small amount of Water Leakage was shut up
- Q:Is there a check valve with a relief valve above?
- Fire check valve is used in the fire pump and fire water tank water outlet flow pipeline, pump regulator with control flow unidirectional flow device where the control flow only one-way flow valve; fire safety valve is used to pump combination device and fire pump outlet pipe to control the pipeline pressure does not exceed the pressure will need to use.
- Q:Check valve h44h-25p what does that mean?
- H- check valve code4- flange connection4- rotary single structureH sealing material is Cr13 stainless steel25-25 kg pressure 2.5MPaP- stainless steel 304
- Q:How much is the check valve for the concrete pump?
- 31 concrete pump price ranging from 15W to 60W, different configurations have different prices, which one do you want?
- Q:Does the tap water return to the water?
- The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
- Q:The working principle and structure description of the mute check valve
- When the valve is in use, the medium flows according to the direction of the arrow.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.
