Swing Check Valve

Q: Furnace blower outlet check valve what: Must install check valve to prevent downtime fan reversal

Q: 40 how large check valves are installed in the water pipes?: Crown valve press40 of the pipe outer diameter of 48 DN40 check valve on it

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.

Q: Why should the check pipe be added to the chilled water pipe of the air conditioning unit?: Check valves are usually installed at the exit of a group of pumps. I have not heard of the installation of check valves at the location of the air conditioning unit.The function of the check valve is to prevent backflow. Prevent backflow of water in water pipe and knock out impeller of water pump.

Q: Back pressure valve and check valve difference: Oil is generally put into the wells of the check valve calling back pressure valveCheck valve is a general name, mainly lifting type and swing type.

Q: What is the purpose of installing a check valve in the air pipe before the fan?: FanA class of air conditioning appliances driven by the electric motor to rotate the blades of the air to drive the airflow and to exchange the air inside and outside the chamber. Also known as fan. The purpose of air exhaust is to remove the foul air in the room and regulate the temperature, humidity and sensory effects. Exhaust fans are widely used in families and public places.

Q: How to prevent the backflow valve of medium: Among them, the check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface. In order to ensure that the valve can reach the appropriate position of the seat surface at any time, the disc is designed in the hinge mechanism so that the disc has enough swing space to make the disc real and comprehensive contact with the valve seat. The disc can be made of either metal or leather, rubber, or synthetic coverage, depending on performance requirements. The swing check valve is almost completely open and the fluid pressure is almost unimpeded, so the pressure drop through the valve is relatively small. The check valve of the lift check valve is located on the valve seat sealing surface of the valve body. In addition to this valve disc is free to lift, like the rest of the cut-off valve, the fluid pressure valve from the valve seat sealing surface lift, medium return led down to the valve seat, and cut off the flow. Depending on the service conditions, the disc can be of all metal construction or in the form of a rubber pad or rubber ring on the valve frame. The same as the cut-off valve, lift check valve fluid through the channel is narrow, so the check valve by lifting the pressure drop than the swing check valve a little bigger, and swing check valve flow restrictions very little.

Q: How to install fire fighting pipe and flue fire check valve?: 4, the installation of flue should each layer as bearing, bearing steel 2 root diameter over 14mm?.5, after the installation of the flue, in each flue check valve of the reserved installation of fire type flue check valve, with special glue mixing cement, coated with a check valve installed in the valve hole edge, and then back to the reservation in check at.6, the construction should be reserved at all levels of the hole, covered with a cover plate, to ensure safety in construction, to prevent construction waste fall into the flue.

Q: Is the tank stop valve a non-return valve or a check valve?: The check valve is not the same as the cut-off valve. The difference between them is mainly that the structure is very different.

Q: What's the difference between the check valve and the stop valve?: The check valve is not the same as the cut-off valve. The difference between them is mainly that the structure is very different.Check valve is a one-way valve, automatically prevent reverse flow of fluid, no knob, can not be artificial blocking forward flow.The valve has a knob, and the controller can control the forward flow. Because of its special structure, the fluid can not flow backwards even if there is no artificial valve.

Yue,located in Ducun Industrial Park, Linhu Town, Wuzhong District, Suzhou, mainly produces valves. Our company is equipped with one scale automatic static coating line, two assembly testing lines, many sets of semi-automatic assembly testing equipment as well as processing equipment such as 5m,3m and 2m vertical lathes, 4m and 2m milling machines and boring machines.
