Description

A kind of flap valve that reduces door leaf unlatching resistance

Technical field

The utility model relates to a kind of flap valve, and especially a kind of flap valve that can reduce door leaf unlatching resistance, belongs to flap valve technical field.

Background technology

Flap valve is mounted in a kind of check valve of rivers limit drainpipe outlet end, is for preventing that outer water from pouring in down a chimney. Flap valve comprises gate seat and door-plate, and gate seat and door-plate are to be movably connected by hinge, and the position of being combined with door-plate on gate seat is provided with the sealing ring of a ring shape. When the hydraulic pressure in flap valve is greater than flap valve outside pressure, door-plate unlatching flap valve is opened; When rivers tidal level is higher than effluent pipe mouth, and external water pressure is while being greater than overpressure, and flap valve is closed automatically, in case rivers tidewater pours in down a chimney in intake-discharge pipe road. When flap valve is closed, sealing ring can prevent that extraneous water is penetrated in flap valve. Flap valve can be used for circular delivery port and the square delivery port of unimodal current, vertebration, and reliable operation just can realize keying without manual operation. Because gate seat and the door-plate of prior art are to link together by a hinges, comparison of resistance when flap valve door leaf is opened is large, and door leaf opening angle can reach 180 °, and opening angle is excessive, and this just affects the stability of flap valve operation.

Summary of the invention

The purpose of this utility model is to provide a kind of flap valve that can reduce door leaf and open resistance, with the technical problem of the flap valve that solves prior art less stable when the operation.

The utility model adopts following technical scheme: a kind of flap valve that reduces door leaf unlatching resistance, comprise the door leaf and the gate seat that are movably connected, between described door leaf and gate seat, be provided with two parallel connectors, one end of each connector by the first rotating shaft be connected on gate seat, the other end is connected on door leaf by the second rotating shaft.

The oblique upper that is positioned at the first rotating shaft on described gate seat is provided with the locating part for limiting door leaf.

On described gate seat, be fixedly connected with two the first fixtures, the first rotating shaft on described two connectors is rotated respectively and is assemblied on two the first fixtures, on described door leaf, be fixedly connected with two the second fixtures, the second rotating shaft on described two connectors is rotated respectively and is assemblied on two the second fixtures, and described locating part is arranged on the first fixture.

Described locating part is strip structure, and the two ends of locating part are separately fixed on two the first fixtures.

The beneficial effects of the utility model are: the utility model by arranging connector between gate seat and door leaf, and connector and door-plate, gate seat are coupled together with two rotating shafts, this flap valve is in opening procedure, water slug flap valve in pipeline, two rotating shafts can facilitate door leaf to open, and reduce door leaf and open resistance. Further, can utilize locating part to carry out flap valve door leaf open angle spacing, prevent that door leaf open angle is excessive, can not impact flap valve operation. The utility model is simple in structure, easy to use, and reduce flap valve and open resistance, and can be reliably spacing.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

The structure of a kind of specific embodiment of the utility model as shown in Figures 1 to 4, the flap valve that the minimizing door leaf of the present embodiment is opened resistance comprises the door leaf 2 and the gate seat 1 that are movably connected, between described door leaf 2 and gate seat 1, be provided with two parallel connectors 3, one end of each connector 3 by the first rotating shaft 31 be connected on gate seat 1, the other end is connected on door leaf 2 by the second rotating shaft 2.

On gate seat 1 in the present embodiment, be fixedly connected with two the first fixtures 11, the first rotating shaft 31 on two connectors 3 is rotated respectively and is assemblied on two the first fixtures 11, on described door leaf 2, be fixedly connected with two the second fixtures 12, the second rotating shaft 32 on described two connectors 3 is rotated respectively and is assemblied on two the second fixtures 12.

The oblique upper that is positioned at the first rotating shaft 31 on described gate seat is provided with the locating part 4 for limiting door leaf 2, this locating part 4 is arranged on the first fixture 11, the locating part 4 of the present embodiment adopts strip structure, and the two ends of locating part 4 are separately fixed on two the first fixtures 11.

By between gate seat and door leaf, connector being set, and connector and door-plate, gate seat are coupled together with two rotating shafts, flap valve in opening procedure, water slug flap valve in pipeline, two rotating shafts can facilitate door leaf to open, and reduce door leaf and open resistance.
