Lift check valve according to its structure and installation of the classification

1, the lift check valve disc is disc-shaped, around the seat channel for rotation shaft rotation, because the valve into the streamline linear flow resistance than the butterfly check valve is small, suitable for low flow rate and Small changes in the flow of occasions occasions, but not suitable for pulsatile flow, the sealing performance is less than the lift. Butterfly check valve single-valve, double-valve and most of the three, these three forms are mainly based on the valve caliber, the purpose is to prevent the media stop flowing or backwards, weakened the hydraulic impact. 2, lift check valve: valve along the valve body vertical centerline sliding check valve, internal thread check valve can only be installed on the level of the pipeline, in the high-pressure small-caliber check valve disc can be used ball . Butterfly check valve body shape and the same cut-off valve (common with the cut-off valve), so it has a larger fluid resistance coefficient. Its structure is similar to the cut-off valve, the valve body and the valve and the cut-off valve the same. The upper part of the valve plate and the lower part of the valve cover are machined with a guide sleeve which is simple and can be freely guided and guided by the valve guide. When the medium flows downstream, the valve plate is opened by the medium thrust. When the medium is stopped, Drop falling on the valve seat, play a role in blocking the media countercurrent. Straight through butterfly check valve medium inlet and outlet channel direction and seat channel vertical; vertical lifting check valve, the media import and export channel direction and valve seat channel in the same direction, the flow resistance than the straight-through small. 3, lift check valve: valve around the valve seat in the rotation of the check valve. Butterfly check valve structure is simple, can only be installed in the horizontal pipe, good sealing. 4, lift check valve: the valve along the valve body center line sliding valve. Pipeline check valve is a new type of valve, its small size, light weight, good processing technology, is one of the development direction of the check valve. But the fluid resistance coefficient is slightly larger than the swing check valve. 5, compression check valve: This valve is used as a boiler feed water and steam shut-off valve, it has a lift check valve and globe valve or angle valve of the integrated function. In addition, there are - some do not apply to the pump outlet installed check valve, such as the end of the valve, spring, Y-type check valve.
