- Q:What happens when the check valve is broken?
- Check valve is broken, there will be back water, down pressure, serious will produce pump reversal, burning motor
- Q:Problems with the check valve of the circulating water pipe
- The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valveThis hydraulic pressure refers to the liquid pressure in the pipeline, not another pressure; the big caliber butterfly valves are small, and the small ones are all one-way valves. Another HB-HV hydraulic check valve, which is used on the oil circuit, the module and the operation circuit, you do not need.
- Q:The self-priming pump with check valve (check valve, water valve)?
- Both, but there are good or bad points, good seal, with a spring, the general is a piece of rubber plus a piece of iron, plus a check valve is feasible
- 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
- Q:Can the swing check valve stand upright?
- Ordinary lift check valves shall not be erected. Lift check valves with springs can also be mounted.
- Q:Check valve can not stop water, how to solve?
- Valve is broken, change one, my family is like this
- Q:What is the function of the stop valve and check valve installed on the water supply pipe?
- 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:What is the HH44X-16 H of the double acting slow closing check valve? Can you explain it in detail?
- 2, micro resistance, slow closing check valve, also known as check valve, its role is to prevent the medium back in the pipeline. The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. 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. Suitable for cleaning medium, not suitable for medium containing solid particles and viscosity.
- Q:The difference between backflow preventer and check valve
- In abnormal pressure (i.e., the outlet pressure is higher than that of the middle cavity), even if the two check valve can not reverse sealing, safety relief valve can automatically open the reverse water emptying, and the formation of air separation, ensure the health and safety of water upstream.
- Q:With no negative pressure water supply, the pump is equipped with a check valve, the construction ring network also needs to install check valve?
- With no negative pressure water supply, the pump is equipped with a check valve, the construction ring network also needs to install a check valve, or else the water pump may enter the ring network.
