Description

Leakproof damping safety check
Technical field
The utility model relates to a kind of leakproof damping safety check.
Background technique
The open-shut device of leakproof damping safety check is opened voluntarily or is closed by media flow and strength, to prevent that valve that medium flows backwards is on leakproof damping safety check.Leakproof damping safety check belongs to the self-acting valve class, is mainly used on the pipeline of medium one-way flow, only allows medium to flow to a direction, to try to avert accidents.Ball-type sewage leakproof damping safety check: valve body adopts the full tunnel structure, has the advantage that flow is large, resistance is little.Adopt ball to do flap, be applicable to high viscosity, industry and the domestic sewage pipe network of suspended matter are arranged.
The model utility content
The utility model provides a kind of reasonable in design, and what stagnant water effect was good can be widely used in tall building, the water supply and sewerage pipeline.
The utility model technical solution problem provides following scheme:
A kind of leakproof damping safety check, comprise valve body, it is characterized in that: have valve pocket in the described valve body, the left side of described valve body, right two ends be respectively equipped with into, water outlet, the upper end of described valve body is provided with opening, be sealed and installed with valve gap on the described opening, has support on the valve pocket inwall of described water intake one side, be hinged with rocking bar on the described support, one end of described rocking bar is installed with flap, be installed with vibration damper plate on the top-right valve pocket inwall of described flap, described vibration damper plate is provided with damping ring, on the sidewall of described valve pocket left side water intake valve seat is installed, and described flap is overlapped on the valve seat, be installed with respectively magnet on the surface of contact of described flap and valve seat, be installed with balancing weight on the described flap.
Between described valve gap and the valve body seal washer is installed.
The utility model reasonable in design is furnished with pouring weight on the flap, stagnant water effect is good, can be widely used in tall building, the water supply and sewerage pipeline.
