Abstract
The utility model discloses an energy-saving left-side opened air elimination type irrigation and drainage flap valve. The flap valve adopts the structure that a flange body is arranged in front of a flange; a special-shaped flange is arranged in front of the flange body; a water seal is arranged on the end face of the special-shaped flange; a valve is arranged in front of the water seal; hinges are arranged on the left side of the special-shaped flange and are in linkage connection with the valve; an air vent valve is arranged at the upper part of the right of the valve; and bolt holes are formed on the flange, and take the cross central line on the face of the flange as criterion to perform displacement to the left by 5 degrees. Owing to the structure, after the flap valve is installed, not only is self-weight horizontal component of the valve used as power to achieve the purpose of reducing the startup resistance and avoiding automatic closing of the valve, but also the air vent valves can be used for eliminating air pressure in pipelines in the moment of starting and closing the valve and reducing frequent impact sound when the valve is started and flapping sound when the valve is closed.
Description
Technical field
The utility model discloses a kind of energy-saving left 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, it is large also not yet to see a kind of opening angle on market, and resistance to water-flow is little, can either save mass energy, can get rid of again the energy-saving left opening releasing irrigation and drainage flap valve valve of the pipeline air pressure of pumping plant.
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 left opening releasing irrigation and drainage flap valve valve of pipeline air pressure.
Technical solutions of the utility model are as follows: a kind of energy-saving left 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 the special-shaped flange left side, hinge connects with valve, is provided with outlet valve in the valve upper right, is provided with bolt hole at flange, the cross centre line of bolt hole on the flanged surface is as benchmark, all to 5 ° of left dislocations, 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.
Key technology of the present utility model is: the upper right at valve is provided with outlet valve, the cross centre line of bolt hole on the flanged surface is as benchmark, all to 5 ° of left dislocations, 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.
