Abstract
The utility model discloses a tiny drag slow shut check valve which comprises a valve body, a water inlet and a water outlet are arranged at two ends of the valve body, a valve plate transversely placed in the valve body is hinged in the inner chamber of the valve body in a rotating manner, a support platform is arranged at the lower end of the valve body, a guide hole is formed in the support platform, a resistance rod is mounted in the guide hole in a sliding manner, a spring is sleeved outside the resistance rod, and a rubber cushion is stuck to the outer lateral wall of the valve rod. The tiny drag slow shut check valve is a security device mounted in a pipeline or at the outlet of a pump, and used for preventing back flow of medium from generating water hammer to push the pump to rotate reversely when the pump stops, and has the advantages of stable and reliable sealing performance, abrasion resistance, long service life, running stability, and no vibration.
Description
Technical field
The utility model relates to the opening/shutting valve class, specifically is a kind of Tiny Drag Slow Shut Check Valves.
Background technique
At present, Tiny Drag Slow Shut Check Valves structural type is of all kinds, and the form of open-close type safety check is arranged; External cushion dashpot form is also arranged; But the buffering when all just needing a kind of liquid to accomplish valve closing is eliminated destructive water hammer, to ensure the property safe and reliable to operation of water supply line facility.But often because the leakage or the obstruction of hydraulic pipe line lose due function.
The model utility content
The purpose of the utility model provides a kind of Tiny Drag Slow Shut Check Valves; Be installed in the pipeline or the delivery side of pump place; Be used for preventing when pump is shut down that medium from flowing backwards produces the safety installations of impact of water hammer pump reversing, sealability is reliable and stable, wear-resistant, long service life, operate steadily, friction.
The technological scheme of the utility model is following:
A kind of Tiny Drag Slow Shut Check Valves includes valve body, and two ends of valve body is respectively water intake, water outlet; Be rotatablely hinged with the valve plate that is horizontally placed in the valve body in the inner chamber of valve body; The lower end of valve body is a support platform, is provided with pilot hole in the support platform, is slidingly fitted with drag strut in the pilot hole; Drag strut is set with spring outward, is bonded with rubber buffer on the outer side wall of described valve rod.
The top of described valve body is equipped with pressure gauge.
The utility model is installed in the pipeline or the delivery side of pump place; Be used for preventing when pump is shut down that the medium refluence from producing the safety installations of impact of water hammer pump reversing, it is big to have the light open degree of flap, and power savings is remarkable; Fluid resistance is little; Sealability is reliable and stable, wear-resistant, long service life, operate steadily, friction, be applicable in the system pipelines such as plumbing, fire-fighting, HVAC or pump outlet prevents that medium from flowing backwards and produces water hammer pipeline or pump are produced harm.
Description of drawings
Fig. 1 is the structural representation of the utility model.
