Description

Energy-saving free side-turning type flap valve

Technical field

Valve arrangement field is the utility model is related to, particularly relates to a kind of energy-saving free side-turning type flap valve.

Background technology

Flap valve, is mainly installed on the tail end of drainage pipeline, has the function of to prevent the non-return valve that outer water pours in down a chimney.Flap valve mainly by Valve seat, valve plate, Mi Tufengquan, four part of hinge are formed.Shape is divided into circular and square.The material of flap valve is traditionally various gold Metal products, have developed into a variety of composite materials now.Flap valve has the function that the positive unidirectional unlatching of runner and reversely closes.

During specific use, the valve deck of flap valve by means of itself counterweight balanced action, under the action of current Door leaf is set to automatically turn on or close, or slightly external force effect is turned on and off door leaf, when flap valve part is ducked in drink, in pipeline Portion's pressure is larger, and when buffer brake is smaller, flap valve allows partial compromise amount, and when river hydraulic pressure increases, flap valve will turn off Sealing, the flap valve operation principle for pumping plant are same as above.

Improvement to flap valve at this stage focuses mostly in following aspect：

A. to the improvement of the door-plate open-shut direction of flap valve, it is allowed to that folding is more convenient, such as the side towards water outlet that is open Top, can rely on gravity to close during closing；

B. to the improvement of each junction of flap valve valve body, junction is allowed to closer to shiny surface, prevents mud debris from accumulating Equipment is impacted in crevice place, extends the service life of equipment；

C. the structure of flap valve is made and is suitably modified, improve its compressive property, ensure safe to use；

However, technology at this stage, in installation process, the problem of all suffering from how could accurately installing, flap valve itself Gravity it is big, mostly need installed by hoisting equipment, in installation process, be aided with human assistance positioning.The process needs Long-time, multiple centering are wanted, expends the time, labor strength is big, and installation accuracy is low, and fouling phenomenon is tight in follow-up use Weight, wastes production capacity.
