Abstract
The utility model discloses a tetragonal right side-overturn type flap valve, having simple and reasonable structure, stable and reliable motion, long life span, big opening angle of the flap, small flow resistance of medium, the auto open and close flap, no open-close machine needed, and great energy conservation and manpower and material resources saving. The utility model comprises a valve body, a circular groove, an upper and lower hinge, an upper and lower axis pin and a flap, the flap fixed on the upper and lower axis pin of the upper and lower hinge. The upper and lower hinge, the upper and lower axis pin and the flap fixed on the valve body have an inclined angle of 5 degrees from left to right on the front end surface of the valve body, as the front end surface of the valve body has an inclined angle of 5 degrees backward. Therefore, the flap opens automatically when the medium pressure in the inner cavity of the valve body is greater than the external back pressure of the flap, and closes automatically when the medium pressure in the inner cavity of the valve body is less than or equal to the external back pressure of the flap. No open-close machine or manual operation is needed.
Description
Technical field
The utility model relates to a kind of irrigation and drainage pumping station equipment, and more particularly, it relates to the right side turn over flap valve of a kind of square valve.
Background technology
At present, both at home and abroad the flap valve valve used of irrigation and drainage pumping station mostly adopts rotating hanging formula flap valve, and this flap valve is difficult to the protection water pump and is not damaged because falling speed is fast, and flap valve could be backed down when needing the medium of body cavity to set up elevated pressures.Because water pump output medium top lift is limited, so the flap valve opening angle is little, energy loss is big, be large-scale flap valve more than the 1.6m by it, need electronic or hydraulic hoist equipment could safety open and close.Up to the present, it is big also not see a kind of flap valve opening angle on market as yet, and the medium circulating resistance is little, the right side turn over flap valve of square that again can automatic open and close valve.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of simple and reasonable, move reliable and stable, the flap valve opening angle is big, the medium circulating resistance is little, and flap valve energy automatic open and close need not headstock gear equipment, not manually-operated can be saved the cubic type side turn over flap valve valve of a large amount of energy and manpower and materials.
The technical solution of the utility model is as follows: the right side turn over flap valve of a kind of square valve, it comprises valve body, cannelure, cuts with scissors ear and flap valve etc. up and down.Wherein the front end face at valve body is provided with the 5 ° of oblique angles that tilt from front to back, the valve body front end face is provided with the cannelure that rubber o-ring is installed, described valve body front end face is provided with and cuts with scissors ear up and down, is provided with lower shaft pin in the ear cutting with scissors up and down, and last lower shaft pin is provided with flap valve.The described ear of hinge up and down that is arranged on the valve body front end face, last lower shaft pin and flap valve at the valve body front end face from the right-to-left 5 ° of oblique angles that tilt.
The beneficial effects of the utility model are: (1) is simple and reasonable, move reliable and stable, long service life; (2) the flap valve opening angle is big, and the medium circulating resistance is little, can save a large amount of energy; (3) flap valve energy automatic open and close need not headstock gear equipment, and not manually-operated can be saved a large amount of manpower and materials.

The specific embodiment
As shown in the figure, the right side turn over flap valve of square valve mainly by valve body 1, cannelure 2, on cut with scissors ear 3, down cut with scissors ear 4, go up pivot pin 5, lower shaft pin 6 and flap valve 7 etc. and constitute.
The front end face of described valve body 1 is provided with the 5 ° of oblique angles that tilt from front to back, described valve body 1 front end face is provided with the cannelure 2 that rubber o-ring is installed, described valve body 1 front end face is provided with hinge ear 3 and cuts with scissors ear 4 down, be provided with pivot pin 5 and lower shaft pin 6 in described upward hinge ear 3 and the following hinge ear 4, described upward pivot pin 5 and lower shaft pin 6 are provided with flap valve 7.
Described valve body 1 front end face is provided with go up hinge ear 3, down cut with scissors ear 4, go up pivot pin 5, lower shaft pin 6 and flap valve 7 at valve body 1 end face from the right-to-left 5 ° of oblique angles that tilt, therefore, after water pump was out of service, flap valve can be closed automatically, can prevent from that medium from flowing backwards rapidly and producing water hammer to damage water pump.
