Abstract
The utility model belongs to the technical field of the manufacturing of valve, especially, relate to a check valve, including the valve body, be equipped with inlet opening and apopore on the valve body, be provided with the disk seat in the inside slope of valve body, the side of valve body is equipped with the valve plate mounting hole, install the valve plate in the valve plate mounting hole, the lower part of valve plate is connected with the connecting block through the cushion, the thickness at connecting block middle part is less than the thickness of both sides, one side with the disk seat contact on the valve plate is equipped with the soft rubber layer. For prior art, this device can make the valve plate swing more nimble through the structure of change valve plate, the design of connecting block, sets up one deck soft rubber layer in one side of valve plate, and under the less condition of flow, this soft rubber lamination is warp greatly on the disk seat, therefore sealing performance is stronger, work as the great condition of flow under, the valve plate of soft rubber layer and vulcanie plays sealed effect jointly, has improved check valve's sealing performance greatly.
Description
Technical field
This utility model belongs to the manufacturing technology field of valve, more particularly to a kind of check-valves.
Background technology
In prior art, many between the valve seat and valve plate of conventional check valves to be coordinated using cylinder inner plane, valve plate adopts rubber
Glue material matter.Stone rubber is typically adopted, valve plate may be caused to enter in valve seat if rate-of flow is excessive, cause sealing
Failure, if the less situation of flow, valve plate coordinates defective tightness with valve seat, then be easy to produce leakage.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of check-valves, can be applied to not
With the medium of pressure, the sealing of valve plate is improved.
This utility model for achieving the above object, is employed the following technical solutions：A kind of check-valves, it is characterised in that：Including
Valve body, valve body are provided with inlet opening and apopore, and the inner inclination of valve body is provided with valve seat, and the side of valve body is provided with valve plate peace
Dress hole, is provided with valve plate in the valve plate installing hole, the bottom of the valve plate is connected with contiguous block, the contiguous block by rubber cushion
Thickness of the thickness at middle part less than both sides, the side contacted with valve seat on the valve plate is provided with soft rubber layer.Relative to existing
Technology, this device make valve plate swing more flexibly, in the side of valve plate by changing the structure of valve plate, being designed to of contiguous block
One layer of soft rubber layer is set, and in the case of flow is less, the soft rubber is laminated on valve seat, deformation is larger, thus close
Sealing property is stronger, and in the case that flow is larger, the valve plate of soft rubber layer and vulcanie plays a part of sealing jointly, greatly
Improve greatly the sealing property of check-valves.
Preferably, external diameter of the external diameter of the soft rubber layer less than the valve plate.It is cost-effective, as long as ensureing soft rubber
Glue-line is adjacent to the outer rim of valve seat.
The beneficial effects of the utility model are:Relative to prior art, structure of this device by change valve plate, connection
Being designed to of block makes valve plate swing more flexibly, arranges one layer of soft rubber layer in the side of valve plate, when the less feelings of flow
Under condition, the soft rubber is laminated on valve seat, and deformation is larger, thus sealing property is stronger, in the case that flow is larger, soft
The valve plate of rubber layer and vulcanie plays a part of sealing jointly, substantially increases the sealing property of check-valves.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of valve plate in this utility model；
Fig. 3 is the side view of Fig. 2.
Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.Such as Fig. 1-Fig. 3 institutes
Show, a kind of check-valves, including valve body 1, valve body is provided with inlet opening and apopore, and the inner inclination of valve body is provided with valve seat 2,
The side of valve body is provided with valve plate installing hole 3, is provided with valve plate 4 in the valve plate installing hole, and the bottom of the valve plate passes through rubber cushion
Contiguous block 5 is connected with, the contiguous block is coordinated with the stopper slot 6 for being arranged on valve plate installing hole bottom, in the middle part of the contiguous block
Thickness of the thickness less than both sides, the side contacted with valve seat on the valve plate is provided with soft rubber layer 7.This device is by changing valve
The structure of plate, being designed to of contiguous block make valve plate swing more flexibly, arrange one layer of soft rubber layer in the side of valve plate, when
In the case of flow is less, the soft rubber is laminated on valve seat, deforms larger, thus sealing property is stronger, when flow it is larger
In the case of, the valve plate of soft rubber layer and vulcanie plays a part of sealing jointly, substantially increases the sealing of check-valves
Performance.
External diameter of the external diameter of the soft rubber layer less than the valve plate.It is cost-effective, as long as ensureing soft rubber layer patch
The outer rim of tight valve seat.
This device makes valve plate swing more flexibly, in valve plate by changing the structure of valve plate, being designed to of contiguous block
Side arranges one layer of soft rubber layer, and in the case of flow is less, the soft rubber is laminated on valve seat, and deformation is larger, because
And sealing property is stronger, in the case that flow is larger, the valve plate of soft rubber layer and vulcanie plays the work of sealing jointly
With substantially increasing the sealing property of check-valves.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
