Q:How many kinds of check valves should be used?: Check valve applies to the occasionThe purpose of the utility model is to prevent the backflow of the medium, and the half of the utility model is provided with a check valve at the outlet of the pump. In addition, a check valve shall be installed at the outlet of the compressor. In a word, check valves shall be installed on the equipment, installations or pipelines to prevent the flow of the medium.Generally in the nominal diameter of 50mm horizontal pipelines are selected vertical lift check valve. Straight through lift check valves can be installed on both horizontal and vertical lines. At the end of the valve is generally installed in the vertical pipe of the pump inlet, and the bottom-up flow of media.Swing check valve can be made at a high working pressure, PN up to 42Mpa, and DN can also do great, maximum up to 2000mm or more. Depending on the material of the housing and the seal, any working medium and any operating temperature range can be applied.

Q:Which kind of steam check valve is good?: Steam check valve selection spring pressure check valve is better, can be sealed tight.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. 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:What is the difference in price between the check valve HH48X-10C and the HH49X-10C?: Since this model has exceeded the standard requirements, so there is no uniform manufacturers. There are dozen HH49X, there are also playing HH48X, HH49X, in fact, are the same kind of valve.

Q:Do you still need to check valve fittings for solar water heater installation?: Need to be installed to prevent hot water from flowing back.The hot water flow is mainly refers to the low pressure tap water (tap water pressure is insufficient to reach the roof) or tap water pressure is not stable and high and low, at this time, Sheung Shui solar water heater, the water heater on the roof, the natural water level drop, the water heater will flow to the water in the road, if there are many hot water heaters, not only not to cold water, the result will make the hot water flow, water reverse, hot water outflow phenomenon caused by the user in tap water downstairs. To solve the backflow of hot water, a check valve is installedIn the control of the water valve can be installed about.

Q:What does the check valve h44t-16 mean?: Flanged swing check valve [H stands for check valve, 4 represents flange, 4 represents structural form (swing type), T represents internal copper alloy, and 16 represents pressure 16 pressure. I hope it will help you

Q:Does the check valve of the flue of the range hood work?: The picture of the check valve of the flue of the range hood is as follows:In addition there is a full sealed flue check valve or smoke exhaust hood treasure is installed in public on the flue pipe valve, exhaust valve to open the hood, hood stop valve is closed, the current Taobao sold this kind of sealed check valve is more, we also evaluated very high. Pictures are as follows:

Q:What is the function of the check valve installed in the water meter before entering the residential water?: Generally installed after the water meter. The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter. A check valve is installed after the water meter, so that the situation can be avoided.The main function of the check valve is to prevent the backflow of the medium, prevent the reverse of the 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 is the working principle of the flue check valve?: The utility model relates to a flue check valve, which belongs to an automatic valve, and the main function of the utility model is to prevent the backflow of oil smoke, and only to flow in one direction, and to prevent the airflow from flowing in opposite directions.Simon common flue check valve is the use of aerodynamics and mechanical principles of lever machinery, the use of South Korea's imports of high-quality ABS LG engineering materials for the material.

Q:The air pipe is equipped with a check valve: The weight of the valve or the gravity of gravity to maintain the valve in the open state of balance, the principle of the same, are heavy torque control of the door opening and closing. Inside and outside the air pressure to destroy the balance, automatic door opening and closing control. An example of simply closing a valve plate by gravity, as in a vertical check valve (Dan Liufa) in a water supply pipe.
