Product Feature:

1, the disc lift check valve disc, seat around tunnel axis rotation, due to the channel into a streamline in the valve, flow resistance is smaller than l butterfly check valve, suitable for low velocity and flow not often change the large diameter of occasions, but should not be used for oscillating flow, its sealing performance than lift.Butterfly check valve points single type, double disc type and for the most part three, the three forms mainly by the valve diameter, the purpose is to prevent the backflow medium flow or stop, decrease hydraulic shock.

2, lift check valve: disc revolve around pin in the seat of the check valve.Disc check valve has simple structure, can only be installed in horizontal pipe runs, sealing is good.
3, lift check valve: disc sliding along the center line of the body of the valve.Pipeline check valve is a new kind of valve, its small size, light in weight and good processing technology, is one of the check valve development direction.But the fluid drag coefficient is slightly superior to swing check valves.

high quality ductile iron cast iron flanged swing check valve

Q:Check valve can not stop water, how to solve?: Valve is broken, change one, my family is like this

Q:Does one-way check valve affect water flow?: The water inlet of the household water heater is equipped with a triangle valve, which will not affect the flow of water, and be convenient for maintenance and inspection

Q:How to install industrial check valves? How should they be used?: 1, straight through lift type 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.2, swing check valve installation location is not appropriate, usually installed in the horizontal pipe, but can also be installed in the vertical pipe or inclined pipe line.

Q:What's the difference between a stop valve and a check valve? Is it a valve?: The cut-off valve is a common valves, mainly used to connect or disconnect the line of medium, generally not for regulating flows.globe valves for a wide range of pressure and temperature, but are generally used for medium and small diameter pipes. The cut-off valve is closed parts (valve) moving along the centerline of the valve seat valve. The stop valve is mainly used for cutting in the pipeline.

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:What does the check valve "H41F" mean?: A check valve is a device for carrying a check valve on a pipe, or a gas will not return

Q:How does the check valve work?: 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:Is the check valve behind or behind the gate valve? Why?: Thank youPlease install it in frontWhat about the front?

Q:How many kinds of structure are there in the check valve?: 3 butterfly check valve structure similar to butterfly valve, its structure is simple, flow resistance is small, water hammer pressure is smaller;4, diaphragm type check valve has a variety of forms, are used as the opening and closing the diaphragm, due to its good waterproof performance, simple structure, low cost, rapid development in recent years, but the use of diaphragm valve temperature and pressure by the diaphragm material limited;

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.
