Left and right displacement, can allow the first fixed block and the second fixed block it is more stable be mounted on valve seat on.Pass through matching for groove and connecting shaft
Conjunction enables to connecting shaft to be connected firmly, to prevent flap to generate displacement.Pass through the cooperation of counterbore and pin so that first
Fixed block and the second fixed block can be stably fixed in valve body, influence leakproofness to prevent flap to generate displacement.
It can prevent flap from generating displacement by the way that the first fixed block and the second fixed block is arranged, to increase the sealing of the utility model
Property and fastness.Fixed both ends of the shaft is inserted in through-hole and can fix the first fixed block and can also prevent while the second fixed block
Shotpin nail abjection, to increase the stability of valve.Fixed shaft end is inserted into lockhole, and lock claw is fixed on the first, second fixation
On block, for the axis that is locked, prevent it from rotating and influencing locating piece, additionally it is possible to prevent pin from deviating from.
The utility model is further arranged to, the torsional spring set there are two and it is oppositely arranged.
Using the above structure, the elastic force between the first flap and the second flap can be increased, increase flap and valve seat
Between leakproofness, reduce impact force that flap is subject to and flap return can be convenient for.
The utility model is further arranged to, and the first flap position corresponding with the second flap is equipped with convex block.
In above structure, convex block can prevent the impact force of medium too greatly and so that the first flap is reversely closed with the second flap
It closes stuck and leads to non-return effect failure.
The utility model is further arranged to, and the valve body external peripheral surface is equipped with protrusion.
Using the above structure, the typefounding on valve body can be convenient for and do not influence the wall thickness of valve body.
The beneficial effects of the utility model：Compared to existing check-valves, the utility model is simple in structure, good airproof performance, jail
Solidity is high.Connecting shaft is enabled to be connected firmly by the cooperation of groove and connecting shaft, to prevent flap to generate displacement.It is logical
Cross the cooperation of counterbore and pin so that fixed block can be stably fixed in valve body, to prevent flap generate displacement and
Influence leakproofness.

Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
A kind of high check-valves of fastness as shown in Figure 1 to Figure 3, including valve body 1, valve seat 2 and flap 3, the valve
Seat 2 is wholely set with valve body 1, and the flap 3 includes the first flap 313 and the second flap 323, first flap 313 and the
Two flaps 323 are articulated and connected by connecting shaft 4, and torsional spring 5 is arranged in the connecting shaft 4, is equipped in the valve body 1 for fixing
