Q:I installed here in the water pump inlet, water pump with a 100 tons of water tank, there are many pumps, long time running, the pump will heat the cylinder, there is no water in the cylinder, the pressure does not go. The water pump is imported. Is the check valve broken or is the installation position wrong?: I told you what the meter said, "check the vacuum meter, and see if the vacuum gauge is pulled down." Without vacuum, there is air, and the possibility of pipeline leakage is greater. Upstairs that the pump is too small power is also a reason, the valve inside the valve holder is a copper block, there is not enough pumping force is not up. If the pipeline is short, that remove the valve tray, the water did not Xikou many words, direct pumping can be pumped up for a moment. Or replaced by the valve stop valve, turn off the valve, the water pump from the water diversion valve. In the opening of the pump at the same time, open the valve, take out the vacuum, there is no valve support will be easy to bring water. Check valve is generally not broken, the problem may be in the pipeline or pump. The pump long time idling is taboo, no water cooling, will be broken, must be careful next time.

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: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:What is the function of the check valve on the air compressor?: Check valve to prevent backflow of gas compressor back to the machine in a series of problems, as followsA gas flow will lead to failure, load startup, startup process if the machine internal high pressure will cause the motor overload start, starting current of the motor will be too high, at the same time, the impact of transmission components is also very large, generally good machine will be some type of protection.Two, multiple units of the system may make the tank filled with water, resulting in the unit can not start properly.Three, because of the shutdown state, most of the air compressor unloading valve is open, so if the gas flow back, but also cause energy losses.

Q:Check valve does not automatically check back, how to adjust?: 7, when installing check valve, should pay special attention to medium flow direction, should make medium normal flow direction and the direction of the arrow on the valve body is consistent, otherwise it will cut off the normal flow of media. Valve should be installed at the bottom of the pump suction pipe.The general formula 8, lift check valve should be installed in horizontal pipe, vertical lift check valve and bottom valve is usually installed in a vertical pipe on the road, and the bottom-up flow of media.9, the check valve closes, will produce water hammer in pipeline pressure, will lead to serious damage to the valve and piping or equipment, especially for the big pipe or high pressure pipeline, it should pay attention to those who use check valve.

Q:The difference between the plunger type check valve and the lift check valve: Lift check valve is to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure 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. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).Hope to be of some help to you!

Q:See English design drawings, found the check valve to a lot of good variety, do not know how to translate, please come and see God, and generous with your criticism.CHECK VALVE I search on the Internet, that is, the meaning of the check valve, but so many kinds, really do not know what it means, not only did not see, never heard of.CHECK VALVE - ANGLECHECK VALVE - ANGLE STOPCHECK VALVE - ANTI WHIPCHECK VALVE - STOPCHECK VALVECHECK VALVE - TILTING DISKCHECK VALVE - WAFERCHECK VALVE - Y STOPHigh reward oh, good answer, I will give you a big additional scores drop, huh, worried about kazakhstan. StopPlease make a explanation according to my offer English name, online copy paste do not explain visual satisfaction, I will give you an additional 20~100.Starbooks | browse 5128: Check valve (One-way valve): check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline. Pump water off the bottom valve check valve also belongs to class.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.

Q:How many kinds of structure are there in the check valve?: 2. The swing check valve rotates around the shaft. Its fluid resistance is generally smaller than the lift check valve, it applies to larger 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 are generally applicable to medium calibre applications. Large diameter pipeline using single swing check valve, in order to reduce water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a kind of fast developing check valve. Multi valve check valve is suitable for large caliber pipeline;

Q:Today, I saw the name of the fire check valve on the drawing of a project. Who knows what this is? I haven't met before: Fire check valve, suitable for installation in the kitchen of the air inlet is connected with the common flue, smoke lampblack machine, lampblack and other indoor air discharge to the roof, can prevent the flue gas in the flue flow, and when the building fire, the fire spread to the common flue, the check valve will automatically shut down, stop to fire you spread the rescue of property and escape more time for you, protect your property and life safety. The fireproof device is sensitive and reliable, and is favorable for environmental protection and improving the fire safety level of the house.

Q:What are the differences between different check valves applications? For example, is the fire pump outlet swing check valve or a silent check valve? According to 35How to recognize single wall corrugated pipe and double wall corrugated pipe? Which is better?.What's the use of the silent check valve? And the bellow problem below, is there no answer?: The application performance of the acoustic check valve only allows the medium to flow in one direction, and prevents flow in the direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow. Not suitable for medium containing solid particles and viscosity. The design of the check valve takes full account of the requirements of the use of the environment, and uses the inclined plate structure to achieve no vibration, no noise, stable operation, and ensure the quiet environment of the hotel and the residential environment, and has the effect of energy saving.
