Description
Technical field
The present invention relates to a kind of flap valve, more particularly to a kind of flap valve with buffer structure.
Background technology
Flap valve is installed on the tail end of drainage pipeline, is to have the function of the non-return valve for preventing that outer water from pouring in down a chimney.At present, common bat
Door mainly has gravity type, floating box type, side turn over.Present flap valve the problem of generally existing impact force, is passing through in closing course
Under the shock of perseverance high intensity, can generate concrete structure cracking, flap valve malformation the problems such as, influence normal use.
The content of the invention
【1】Technical problems to be solved
The technical problem to be solved in the present invention is to provide it is a kind of it is simple in structure, can effectively buffer door leaf be closed when impact force
The flap valve with buffer structure.
【2】The technical solution solved the problems, such as
The present invention provides a kind of flap valve with buffer structure, and including gate seat 2 and door leaf 1, the upper end of the gate seat 2 is equipped with
Articulated structure 3, the door leaf 1 are hinged on by the articulated structure 3 on the gate seat 2, and the front end of the gate seat 2 is equipped with annular
Groove, the rear end of the door leaf 1 are equipped with the rubber ring 6 of cooperation corresponding with the annular groove, the annular groove inner circumferential
Sliding slot is evenly equipped with, buffer structure is equipped in the sliding slot, the buffer structure includes piston rod 5 and spring 7, the piston rod 5
Front and back end be respectively equipped with buffer part and piston, the piston slide fit is in the sliding slot, the end of the piston and the cunning
It is connected between the bottom surface of slot by the spring 7, the front end of the sliding slot is equipped with limit protrusion, and the limit protrusion is located at described
Between buffer part and the piston.
Further, the buffer structure totally 3, and one of them described buffer structure be located at the gate seat 2 just under
Side.
Further, the front and back end of the buffer part is equipped with rubber pad.
Further, the front end of the door leaf 1 is equipped with handle 4.
Further, the cross section of the rubber ring 6 is isosceles trapezoid.
【3】Advantageous effect
The present invention has the flap valve of buffer structure, simple in structure, can effectively buffer impact force when door leaf is closed, ensure
Flap valve is protected well while door leaf safety shutdown, is damaged to prevent flap valve in knockout process.
Description of the drawings
Fig. 1 is the structure diagram for the flap valve that the present invention has buffer structure；
Fig. 2 is the sectional view for the flap valve that the present invention has buffer structure；
Fig. 3 is the A portions enlarged drawing of Fig. 2.
Specific embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is discussed in detail.
Refering to Fig. 1 to Fig. 3, the present invention provides a kind of flap valve with buffer structure, including gate seat 2 and door leaf 1, gate seat
2 upper end is equipped with articulated structure 3, and door leaf 1 is hinged on by articulated structure 3 on gate seat 2, and the front end of gate seat 2 is equipped with annular groove,
The rear end of door leaf 1 is equipped with the rubber ring 6 of cooperation corresponding with annular groove, and annular groove inner circumferential is evenly equipped with sliding slot, in sliding slot
Equipped with buffer structure, buffer structure includes piston rod 5 and spring 7, and the front and back end of piston rod 5 is respectively equipped with buffer part and piston,
Piston slide fit is connected in sliding slot between the end of piston and the bottom surface of sliding slot by spring 7, and the front end of sliding slot is equipped with limit convex
It rises, limit protrusion is between buffer part and piston.
Buffer structure totally 3, and one of buffer structure is located at the underface of gate seat 2, the front and back end of buffer part is all provided with
There is rubber pad, rubber pad is used for buffering percussive force, and the front end of door leaf 1 is equipped with handle 4, and the cross section of rubber ring 6 is isosceles trapezoid.
Its operation principle is：Gate seat is connected with pipeline, when pipeline needs cutout, the hydraulic pressure in pipeline is less than outside door leaf
Hydraulic pressure, door leaf is voluntarily closed under dead weight and hydraulic pressure, and during closing, door leaf can first strike buffer part, door leaf after
Reforwarding is moved so that and piston compresses spring, reduces the impact force of door leaf, and the rubber pad on final door leaf is bonded with annular groove,
And the rear end of buffer part is bonded with limit protrusion, the front end face of buffer part is overlapped with the bottom surface of annular groove, and door leaf is closed, and works as pipe
When road needs draining, door leaf needs to open, and the water pressure in pipeline is more than door leaf external water pressure, in the effect of spring and hydraulic pressure
Under, door leaf is opened, the water discharge in pipeline.
The present invention has the flap valve of buffer structure, simple in structure, can effectively buffer impact force when door leaf is closed, ensure
Flap valve is protected well while door leaf safety shutdown, is damaged to prevent flap valve in knockout process.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
