Description

A kind of valve
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of valve.
Background technique
The use of valve needs to have very good sealing performance, prevents from leaking during use, wastes Resource, initiation failure etc..It therefore can connector to valve etc. be each may clearance leakage in the design of valve Carry out sufficient sealing in place.
If patent announcement number is CN205371795U, set in pipe joint equipotential close provided with the progress of the sealing elements such as rubber Envelope.But the elastic sealing elements such as rubber can exist during use the problems such as aging, contraction cause sealing element fail and It is leaked.Sealing element can only be carried out to replacement can be only achieved required sealing performance.
But have many piping connections that can not carry out the sealing element of dismounting and change failure, maintenance is caused greatly Inconvenience rises maintenance cost.
Therefore, how the sealing element of failure of adjustment makes it restore sealing performance and reach requirement and be one to need to solve The problem of.
Utility model content
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of valve, this is practical new Type the technical problem to be solved is that: how the sealing element of failure of adjustment make its restore sealing performance reaches requirement.
The purpose of this utility model can be realized by the following technical scheme:
This valve includes spool and valve body, and the spool is connected to form movable component cavity with valve body, the folding group Movable component is equipped in part cavity, the movable component has water inlet end and water outlet, and the valve body is equipped with and water inlet end phase The water inlet of connection is additionally provided with the water outlet being connected with water outlet on the valve body, it is characterised in that: the water inlet end and valve Sealing ring is equipped between internal wall, the water inlet, which is equipped with, can squeeze the extrusion that sealing ring generates deformation.
Its working principles are as follows: the water inlet end of movable component is connected to the water inlet on valve body, it is provided with therebetween Sealing ring connects water inlet end and water inlet to form water inlet flow channel, and passes through sealing ring for feed water flow by sealing ring Road comes with the isolation of movable component cavity, and the folding of movable component can control the Inlet and outlet water of valve, when sealing ring aging is shunk When loss of seal performance, by the way that extrusion is mobile to sealing ring, extruding sealing ring makes it generate deformation for water inlet end and water inlet The connection closed between mouthful, reaches requirement.
In a kind of above-mentioned valve, the water inlet is equipped with screw thread one, and the outer surface of extrusion is equipped with and screw thread one The screw thread two of cooperation.By the screw thread rotation between screw thread one and screw thread two, enable extrusion towards sealing ring movement to increase To the pressure of sealing ring, its deformation is made to reach sealing effect.
In a kind of above-mentioned valve, the extrusion offers recessed with screwing tool cooperation far from one end of sealing ring Slot.The tool that the setting of groove can make the use of extrusion that can arbitrarily be caught in groove makes its rotation, increases the compression of sealing ring Amount, reaches sealing effect, easy to maintenance.
In a kind of above-mentioned valve, the extrusion is equipped with close to one end of sealing ring and squeezes end, the pressed end Portion is tapered or spherical or arc.The these types of shape for squeezing end can make to squeeze the first contact between end and sealing ring It is to be contacted for line, becomes face contact as extrusion presses further towards sealing ring, the pressure of extrusion towards sealing ring is more balanced, It is more efficient to the function of restoring sealing.
In a kind of above-mentioned valve, the sealing ring is arranged around water inlet end inner wall, and sealing ring is affixed with end is squeezed The inner wall leaned on is in the conical surface or ladder-like step surface or cambered surface.Since the conical surface or ladder-like step surface or cambered surface are the internal diameters for having one end It is greater than other end of internal diameter, is that sealing ring can reach sealing performance after assembling, and can have after shrinking failure Enough surpluses can be extruded recovery service performance.
In a kind of above-mentioned valve, the sealing ring fits with movable component, and sealing ring is close to extruding end one end Internal diameter be less than far from squeeze end one end internal diameter.Sealing ring and movable component and fitting for valve body can play effectively Sealing function, anti-impervious liquid form a complete runner.
In a kind of above-mentioned valve, the sealing ring is arranged around water inlet end inner wall, and sealing ring is close to extruding end one The internal diameter at end is greater than far from the internal diameter for squeezing end one end.
In a kind of above-mentioned valve, the spool is equipped with to close with spool and valve body and be bonded with the junction of valve body Sealing ring.
Compared with prior art, the utility model has the advantage that
1, after sealing ring loss of seal performance, reached by the extruding to it using seal request;2, on extrusion The groove opened up keeps adjusting extrusion more convenient, improves efficiency;3, valve is repaired, to solve resource.
