Description
Technical field
The utility model is related to valve, more specifically refers to rubber flap check valve.
Background technology
Rubber flap check valve is a kind of conventional valve, is mainly used in preventing the reverse flow of fluids in pipeline, causes equipment
Damage, rubber flap check valve includes valve body and the encapsulated flap in valve body.
Existing rubber flap check valve is typically provided bonnet, and one end of valve plate is typically hinged on bonnet, and structure is more multiple
Miscellaneous, body is larger, can only be installed during installation by flange, is not easy to install.
Therefore, it is necessary to design a kind of rubber flap check valve, small volume saves material, and simple in construction, installation side
Just.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, and there is provided rubber flap check valve
To achieve the above object, the utility model uses following technical scheme：Rubber flap check valve, including valve body and valve
It is provided with plate, the valve body in passage, the valve body and is provided with valve plate connecting seat, the valve plate connecting seat and the valve body
Design, the upper end of the valve plate is hinged with the valve plate connecting seat, and the lower end of the valve body is located at the water inlet of the passage,
The two ends of the valve body are respectively equipped with mounting hole.
Its further technical scheme is：The valve plate is full lining glue valve plate.
Its further technical scheme is：The full lining glue valve plate includes metal foil and positioned at the outer of the metal foil
The line with rubber on surface.
Its further technical scheme is：Boss is provided with the valve body, the boss is located at the water inlet of the passage,
And the lower end of the valve body abuts the boss.
Its further technical scheme is：The valve plate is cylindrical.
Its further technical scheme is：Length of the boss close to one end of the valve plate connecting seat is more than away from described
The length of one end of valve plate connecting seat.
The beneficial effect of the utility model compared with prior art is：Rubber flap check valve of the present utility model, by
The valve plate connecting seat of design in conjunctionization in valve body, upper end and the valve plate connecting seat of valve plate are hinged, and reduce the design of bonnet,
Overall is simple in construction, small, saves material, using the mounting hole at valve body two ends, can be installed, can passed through by flange
Folder is installed, it is easy for installation.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Brief description of the drawings
The cutting structural representation for the rubber flap check valve that Fig. 1 provides for the utility model specific embodiment.
Embodiment
In order to more fully understand technology contents of the present utility model, with reference to specific embodiment to skill of the present utility model
Art scheme is further described and illustrated, but is not limited to this.
Specific embodiment as shown in Figure 1, the rubber flap check valve that the present embodiment is provided, including valve body 1 and valve plate, valve
It is provided with body 1 in passage 3, valve body 1 and is provided with valve plate connecting seat 2, valve plate connecting seat 2 and the integrated design of valve body 1, the upper end of valve plate
It is hinged with valve plate connecting seat 2, the lower end of valve body 1 is located at the water inlet of passage 3, and the two ends of valve body 1 are respectively equipped with mounting hole 6.
Valve plate connecting seat 2 is used to be flexibly connected valve plate, plays moving fulcrum.
Above-mentioned rubber flap check valve, by the valve plate connecting seat 2 of design in conjunctionization in the valve body 1, valve plate it is upper
End is hinged with valve plate connecting seat 2, and overall is simple in construction, small, saves material, can using the mounting hole 6 at the two ends of valve body 1
, can be easy for installation by being installed to folder to be installed by flange.
When water or other liquid flow into the valve from water inlet, water jet propulsion valve plate is moved towards the direction away from water inlet
Dynamic, so as to open the valve, water can flow out from water outlet, when water outlet has water to pour in down a chimney, and water jet propulsion valve plate is towards close
The direction movement of water inlet, now, valve plate closure water inlet so that water can not flow back, and play a part of non-return.
In the present embodiment, valve plate is full lining glue valve plate, and the sealing of full lining glue valve plate preferably, can greatly prevent
Only flow backwardses or the phenomenon of backflow occur.
The full lining glue valve plate includes metal foil 4 and the line with rubber 41 positioned at the outer surface of the metal foil 4.
Further, boss 5 is provided with valve body 1, boss 5 is located at the water inlet of passage 3, and under the valve body 1
End abuts the boss 5, and so, valve plate can just cover whole water inlet, it is to avoid leak.
In the present embodiment, the rounded shape of valve plate.Certainly, in other embodiment, above-mentioned valve plate can be in other shapes.
In addition, length of the boss 5 close to one end of valve plate connecting seat 2 is more than the length of one end away from valve plate connecting seat 2,
So, valve plate, when water inlet is intake, only needs the strength of very little just in being in tilted layout from top to bottom towards the direction away from water inlet
Valve plate can be opened, in the current backflow of delivery port, current are more fierce, and valve plate closes water inlet closer to water inlet
It is tighter, improve the non-return effect of whole check-valves.
In addition, the valve plate connecting seat 2 is located at the top of the boss 5, the articulated position of valve plate connecting seat 2 and valve plate is not
Whole water inlet can be sealed to valve plate to impact.
Above-mentioned boss 5 is in integrated design with above-mentioned valve body 1, saves material, certainly, and boss 5 can also with valve body 1
It is separation design.
It is above-mentioned that technology contents of the present utility model are only further illustrated with embodiment, in order to which reader is easier to understand,
But embodiment of the present utility model is not represented and is only limitted to this, and any technology done according to the utility model extends or recreated,
By protection of the present utility model.Protection domain of the present utility model is defined by claims.
