Abstract
The utility model discloses a square free side-flap gate valve mechanism with original design psychology, simple, rational structure, unique running orbit, great opening angle of flap gate and small resistance of medium circulation, including a valve body, circular groove, hinge lug, flap gate, upper and lower pins and fixing rod, the flap gate is fixed on the upper and lower shaft pins of the upper and lower hinge lugs, if the medium pressure of the valve inner cavity is greater than the back pressure out of the flap gate, the flap gate would open automatically and the flap gate would drop automatically if the medium pressure is smaller or equal to the back pressure out of the flap gate,, all the procedures need no hand, electrical, gas and liquid control as well as manual operations.
Description
Technical field
The utility model relates to a kind of irrigation and drainage pumping station equipment, is the free side turn over flap valve of a kind of square valve by it.
Background technique
At present, the flap valve valve used of domestic and international various irrigation and drainage pumping station has only rotary-open type and two kinds of structures of vertical side gate-type.Though this flap valve valve also can be protected water pump and prevent that flood from flowing into farmland and urban street, opening angle is little, energy loss is big, is vertical side gate-type flap valve by it, needs artificial or hoist equipment just can be closed, the characteristic requirement of the irrigation and drainage that are far from suitable flood control.
Summary of the invention
The purpose of this utility model provides that a kind of design concept is strange, simple and reasonable, running orbit is unique, resistance to water-flow is minimum, not only can automatic on-off, and move reliable and stable, sealing effect is good, can save the free side turn over flap valve of the square valve of a large amount of energy and manpower and materials.
The technical solution of the utility model is, the free side turn over flap valve of a kind of square valve, it comprise valve body, circular groove, up and down cut with scissors ear, flap valve, go up lower shaft pin and positioning rod.Described valve body front-end face is provided with the 7 ° of oblique angles that recede, also be provided with the circular groove that rubber o-ring is installed on the described valve body front-end face, also be provided with on the described valve body front-end face cut with scissors up and down ear, up and down cut with scissors in the ear on lower shaft pin be provided with flap valve, the behind that described flap valve is opened also is provided with positioning rod, the opening angle of restriction flap valve.
Of the present utility model holding a little is: when the pressure medium of body cavity during greater than the outside back pressure of flap valve, flap valve is just opened automatically; Little or when equaling the outside back pressure of valve, flap valve promptly falls valve port is sealed automatically, need not hand, electricity, gas, hydraulic control system, not manual operation when the pressure of body cavity.

Embodiment
As shown in the figure, the free side turn over flap valve of square valve mainly by valve body 1, circular groove 2, on cut with scissors ear 3, flap valve 4, down cut with scissors ear 5, go up pivot pin 6, lower shaft pin 7, positioning rod 8 etc. and constitute.The front-end face of described valve body 1 is provided with the 7 ° of oblique angles that recede, also be provided with the circular groove 2 that rubber o-ring is installed on described valve body 1 end face, described valve body 1 end face is provided with hinge ear 3 and cuts with scissors ear 5 down, described going up in hinge ear 3 and the following hinge ear 5 is provided with pivot pin 6 and lower shaft pin 7, described upward pivot pin 6 and lower shaft pin 7 are provided with flap valve 4, and the behind that described flap valve 4 is opened is provided with the opening angle of positioning rod 8 restriction flap valves.
This practical characteristics are: when the pressure medium of valve body 1 inner chamber during greater than flap valve 4 outside back pressures, flap valve 4 is just opened automatically, when the pressure medium of valve body 1 inner chamber is less than or equal to flap valve 4 outside back pressures, flap valve 4 just falls to sealing valve port automatically, need not hand, electricity, gas, hydraulic control system, not manual operation.
