Description
Technical field
The utility model relates to a kind of valves, belong to mechanical basic part and manufacturing technology field.
Background technique
Valve be in the fluid system, for control the direction of fluid, pressure, flow device, be to make piping and equipment
Interior medium (liquid, gas, powder) flows or stops and can control the device of its flow.In kill-job, valve also has to pass
Important role, in common kill-job valve, traditional valve is an one-way cock, and when there is water flow, valve is opened, when
When not having water flow, valve is closed.After a protracted use, valve single-way switch is easy because frequently opening traditional kill-job valve
It closes and is broken.Kill valve goalkeeper loses the effect of itself after fracture, serious to may also result in safety accident.
The content of utility model
The purpose of this utility model is to provide a kind of kill-job valve, solve in use for some time, valve it is unidirectional
The problem of switch is broken because of fatigue.
To solve the above-mentioned problems, the utility model uses following technological means:
A kind of kill-job valve includes rubber stopper, and the rubber stopper bottom is provided with supporting layer, connection in the middle part of the supporting layer
There is fixed channel, bolt is installed in the fixed channel, stop nut, the end peace of the bolt are installed on the bolt
Equipped with fixture nut, bolt is fixed on baffle, the head of the bolt is installed for the stop nut and the fixture nut
There is compressed spring, for the compressed spring in the lower section of supporting layer, the rubber stopper is rubber stopper up and down.
Preferably, respectively sealant, fastened layer, buffer layer that the radius of the rubber stopper from top to bottom is sequentially reduced,
The fastened layer and the buffer layer are truncated cone-shaped, and the buffer layer is connect with supporting layer.
More preferably, the baffle includes fixed plate, and the lower part of the fixed plate is provided with rubber pad.
Further, the head of the bolt is crosshead.
Further, the supporting layer includes bracing ring and support foot, and the bracing ring is connected to fixed channel, the branch
Support foot is connected to bracing ring surrounding, and there are three the support foots, and the angle between each support foot is 120 °.
It is also possible that the outer diameter of the compressed spring is gradually reduced from top to bottom, the lower end outer diameter and spiral shell of the compressed spring
The head outer diameter of bolt is identical, and the material of the compressed spring is stainless steel material.
Compared with existing conventional Well Killing valve, the utility model has the following beneficial effects: by the way that a center is engraved
Empty rubber stopper is fixed on bolt, supports entire rubber stopper with a compressed spring, and rubber stopper is fixed on baffle by bolt,
When there is water flow, the engraved structure that water flow is led in the middle part of rubber stopper is impacted below baffle, baffle is rushed, water is just from baffle and rubber
Space passes through between rubber plug.When water stops, because the effect of compressed spring, baffle are pulled original position, between rubber stopper again
Space disappear, achieve the purpose that water blocking, by the single-way switch that will be mechanically connected, be changed to have with spring controlled baffle
Effect prevents in use for some time, and the single-way switch of valve is broken because of fatigue, improves the robustness of valve.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figure 1, in one embodiment of the utility model, a kind of kill-job valve, it is characterised in that: the valve
Including rubber stopper 4,4 bottom of rubber stopper is provided with supporting layer 7, and fixed channel 9 is connected in the middle part of the supporting layer 7, described
Bolt 5 is installed in fixed channel 9, stop nut 8 is installed, the end of the bolt 5 is equipped with fixed spiral shell on the bolt 5
Mother 1, bolt 5 is fixed on baffle 2 by the stop nut 8 and the fixture nut 1, and the head of the bolt 5 is equipped with pressure
Contracting spring 6, for the compressed spring 6 in the lower section of supporting layer 7, the rubber stopper 4 is rubber stopper up and down.
In the present embodiment, by the way that the rubber stopper 4 of a center hollow out to be fixed on bolt 5, with a compressed spring 6
Entire rubber stopper 4 is supported, rubber stopper 4 is fixed on 2 lower section of baffle by bolt 5, and when there is water flow, water flow leads to 4 middle part of rubber stopper
Engraved structure impacts on baffle 2, and baffle 2 is rushed, and just the space between baffle 2 and rubber stopper 4 passes through water.When water stops
When, because of the effect of compressed spring 6, baffle 2 is pulled original position again, and the space between rubber stopper 4 disappears, and reaches the mesh of water blocking
, by the single-way switch that will be mechanically connected, it is changed to be effectively prevented using a period of time with spring controlled baffle
Afterwards, the single-way switch of valve is broken because of fatigue, improves the robustness of valve.
In a new embodiment of the utility model, in order to improve the sealing effect of rubber stopper 4, the rubber stopper 4
What radius from top to bottom was sequentially reduced is respectively sealant 41, fastened layer 42, buffer layer 43, the fastened layer 42 and described slow
Rushing layer 43 is truncated cone-shaped, and the buffer layer 43 is connect with supporting layer 7, by setting three-decker for rubber stopper, from up to
Under each serve as sealing, fastening, buffer water flow effect, can be stably mounted at water outlet for rubber stopper has very big side
It helps；Preferably, in order to prevent when no water flow passes through, gap of the water flow between rubber stopper and baffle overflows, the gear
Plate 2 includes fixed plate 21, and the lower part of the fixed plate 21 is provided with rubber pad 22, the gap between rubber stopper 4 and rubber pad 22
Can be smaller than gap of the rubber stopper 4 directly between fixed plate 21, to improve the sealing performance of entire valve, effectively prevent
When there is no water flow, valve is from there is the case where leak.
In another embodiment of the utility model, further, in order to reduce the maintenance difficulty of valve, the spiral shell
The head of bolt 5 is crosshead because crosshead compared to traditional manifold have it is laborsaving, facilitate mechanical electric tool to use
Advantage, therefore the difficulty that valve is dismantled can be effectively reduced using crosshead；Further, in order to improve entire rubber stopper
4 degree of stability, the supporting layer 7 include bracing ring 71 and support foot 72, and the bracing ring 71 is connected to fixed channel 9, described
Support foot is connected to 71 surrounding of bracing ring, and there are three the support foots 72, and the angle between each support foot 72 is 120 °,
The stress for more optimizing supporting layer makes entire rubber stopper 4 more durable；Furthermore in order to improve the service life of compressed spring 6, subtract
Few got rusty because of compressed spring 6 reduces the service life of kill-job valve, and the outer diameter of the compressed spring 6 gradually subtracts from top to bottom
Small, the lower end outer diameter of the compressed spring 6 is identical as the head outer diameter of bolt 5, and the material of the compressed spring 6 is stainless steel
Material, stainless steel material can effectively prevent compressed spring and reduce service life because getting rusty.
