Abstract
The utility model discloses an energy-saving right-side-opening gas-removing type irrigation and drainage flap valve. A flange body is arranged in front of a flange. An abnormal-shaped flange is arranged in front of the flange body. A water seal is arranged on the end face of the abnormal-shaped flange. A valve is arranged in front of the water seal. A hinge is arranged on the right of the abnormal-shaped flange and is connected with the valve. An exhaust valve is arranged on the upper left of the valve. Bolt holes are arranged on the flange and are displaced rightward 5 degrees based on a cross-shaped central line on the face of the flange. After thus arranged, the energy-saving right-side-opening gas-removing type irrigation and drainage flap valve not only can use self weight horizontal component as motive power to achieve the purposes of reduction of opening resistance of and automatic closing of the valve, but also can remove pipeline air pressure and reduce frequent collisions at the time of opening of the valve and flapping noise at the time of closing of the valve by utilizing the instance of opening and closing of the an exhaust valve.
Description
Technical field
The utility model discloses a kind of energy-saving right side opening releasing irrigation and drainage flap valve valve.
Background technique
The defectives such as at present, what irrigation and drainage pumping station both domestic and external generally used is a kind of Swing check valve, and this Swing check valve exists opening angle little, and resistance to water-flow is large, and energy loss is many.Up to the present, also not yet see a kind of opening angle large on market, resistance to water-flow is little, can either save mass energy, can get rid of again the energy-saving right side opening releasing irrigation and drainage flap valve valve that the pumping plant pipeline gas is pressed.
Summary of the invention
The purpose of this utility model provides that a kind of opening angle is large, and resistance to water-flow is little, can either save mass energy, can get rid of again the energy-saving right side opening releasing irrigation and drainage flap valve valve that the pumping plant pipeline gas is pressed.
Technical solutions of the utility model are as follows: a kind of energy-saving right side opening releasing irrigation and drainage flap valve valve, comprise flange, flange body, the abnormity flange, water seal, valve, hinge, outlet valve and bolt hole etc., wherein, be provided with flange body in the flange front, be provided with special-shaped flange in the flange body front, be provided with water seal at special-shaped end face of flange, be provided with valve in the water seal front, be provided with hinge on special-shaped flange the right, hinge connects with valve, is provided with outlet valve on the valve upper left side, is provided with bolt hole at flange, the cross centre line of bolt hole on the flanged surface is as benchmark, all displacement to the right is 5 °, like this, and after the utility model is installed, can either utilize the deadweight horizontal component of valve to be used as power, reach the unlatching resistance that reduces valve and the purpose of automatic door-closing; Can utilize again the moment of outlet valve when valve opening and closing, get rid of air pressure, the frequent bump when reducing valve opening and the bat chorus sound at closing time of pipeline.
Key technology of the present utility model is: the upper left side at valve is provided with outlet valve, the cross centre line of bolt hole on the flanged surface is as benchmark, all displacement to the right is 5 °, like this, after the utility model is installed, can either utilize the deadweight horizontal component of valve to be used as power, reach the unlatching resistance that reduces valve and the purpose of automatic door-closing; The moment of outlet valve when valve opening and closing be can utilize again, pipeline air pressure, the frequent bump when reducing valve opening and bat chorus sound at closing time got rid of.
