Usage/Applications Of Iron Check Valve
Check valve is to rely on the flow of the media itself and automatically open, close the valve flap, used to prevent the media back valve, also known as the check valve, Dan Xiangfa, counter flow valve, and back pressure valve. Check valve is an automatic valve, its main role is to prevent the media back, to prevent the pump and drive motor reversal, as well as the release of the container medium.

- Q:What is the function of the ventilator's check valve?
- The flue check valve refers to the automatic opening and closing valve plate, which is used to prevent the backflow of soot through the thermal flow of the range hood. It is also called the smoke back valve, the smoke prevention treasure and the flue isolator.
- Q:Can the check valve be used on the steam pipe?
- The check valve can be used on the steam pipe, but only the right material.General steam pressure WCB, temperature and pressure with the then high chromium molybdenum steel. The inside of the valve should be taken into account, depending on the pressure difference.
- Q:Check valve h42h-dn80 what does that mean?
- According to the provisions of the JB/T 308-2004 valve type programming method:H = check valve4 = connection: flange2 = structure form: vertical lifting typeH = sealing surface material: Cr13 stainless steelDN80== nominal diameter: 80mm
- Q:What are the specifications of the DN200 check valve?
- DN200 is a specification.The principle of the check valve, the check valve, the opening and closing parts, depend on the flow of the medium and the power to open or close on its own, so as to prevent the backflow of the medium, called the 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. The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve. The lift check valve can be divided into two types: vertical and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly check valve for straight through, more than a few kinds of check valve, in the form of connection can be divided into thread connection, flange connection and welding three. A check valve is a valve that automatically prevents the flow of fluid. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the exit side, the valve automatically closes under the influence of fluid pressure, gravity and other factors to prevent fluid flow backwards.
- Q:In the water supply system, water pump and water pump without check valve, a water output to another without pump water pump, effect of rotation, it will cause what kind of damage to the pump?
- LZ said that the case does not matter with the check valve, in that case, in addition to affecting performance, it does not matter.
- Q:Should the kitchen check be mounted on the wall or on the hood?
- Buy their own check valve is generally in the wall of the hole, the hood of the smoke machine, usually with a check valve.
- Q:What is the difference between the silent check valve and the silent check valve?

- Q:What does the check valve "H64" and "H14" mean?
- H check valve6 welding connection1 threaded connection4 swing check valveJB/T308-2004< valve type programming method >There should also be sealing surface material code and nominal pressure level
- Q:What can I do with the lift check valve?
- 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. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure.
- Q:What kind of valve does the check valve belong to?
- 1. check valves are automatic valves;2., if the valve is cast iron, can be cast iron valves; if the valve is cast steel, can be cast steel valves; of course, can also beIn copper valves, stainless steel valves,,,,,,,3., if used in steam, can belong to the steam valve
