Abstract
The utility model relates to a flap valve. The flap valve comprises a flap valve seat and a flap valve cover hinged on the flap valve seat; a sealing groove is formed in the flap valve seat; a cavity is formed in the flap valve cover; a sealing bulge is arranged at the inner side of the flap valve cover; the sealing groove and the sealing bulge are paired; a hydraulic buffer is installed on the end portion of the flap valve seat. The flap valve disclosed by the utility model is simple in structure, and capable of reducing an impact force on the flap valve seat.
Description
Technical field
The utility model relates to a kind of drainage and irrigation equipment, particularly relates to a kind of flap valve.
Background technology
Flap valve valve is widely used in the hydraulic engineerings such as drainage and irrigation station, power station, river course, aquaculture, reservoir, sewerage treatment and municipal and environment-friendly.Common flap valve is comprised of flap valve valve body and flap valve valve gap, and flap valve valve body and flap valve valve gap are connected through the hinge.Flap valve is mounted in a kind of one way valve of drainpipe outlet, and the hydraulic pressure in flap valve is greater than flap valve outside pressure and opens, otherwise closes.In practical application, the sealing means generally adopting is line contact sealing, when flap valve drops down onto flap valve seat, can produce noise, and larger to the impact force of weather strip.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can reduces noise, and reduces the flap valve to the impact force of flap valve seat.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of flap valve, comprise flap valve seat and be hinged on the door-slapping cover on flap valve seat, on described flap valve seat, be provided with sealed groove, described door-slapping cover inside is provided with cavity, and the inner side of door-slapping cover is provided with seal convexity, described sealed groove and seal convexity match, and the end of described flap valve seat is provided with oil buffer.
On the basis of technique scheme, the utility model can also be done following improvement,
Further, it also comprises sensor, and described sensor setting is in the end of flap valve seat.
The beneficial effects of the utility model are:
1. at former flap valve gate seat place, increase oil buffer, at door body drop oil buffer service gate body when approaching gate seat, slowly reset, reduce the impact force to gate seat, weather strip, reach protection weather strip and elimination
2. the object of noise.
3. by sensor, detect the tightness of flap valve, with the position of this regulator solution compression buffer.
4. the utility model is simple in structure, easy to operate, and practicality is high.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of flap valve described in the utility model specific embodiment 1;
Fig. 2 is the front view of the local A of a kind of flap valve described in the utility model specific embodiment 1.
In accompanying drawing, the list of parts of each label representative is as follows:
1, flap valve seat, 2, door-slapping cover, 3, cavity, 4, sealed groove, 5, seal convexity, 6, oil buffer, 7, sensor.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of flap valve, comprise flap valve seat 1 and be hinged on the door-slapping cover 2 on flap valve seat 1, on described flap valve seat 1, be provided with sealed groove 4, described door-slapping cover 2 inside are provided with cavity 3, and the inner side of door-slapping cover 2 is provided with seal convexity 5, described sealed groove 4 and seal convexity 5 match, the end of described flap valve seat 1 is provided with oil buffer 6, when door-slapping cover falls, oil buffer has played the effect of buffering, it also comprises sensor 7, described sensor 7 is arranged on the end of flap valve seat 1, by sensor 7, detect the sealing of door-slapping cover 2, with this, come the position of regulator solution compression buffer 7.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
