Description

Valve adopting detachable sealing structure

Technical Field

The utility model relates to an adopt valve that can dismantle seal structure belongs to the valve field.

Background

The valve is a device for controlling the direction, pressure and flow of fluid in a fluid system, a density structure in contact with a valve clack in the existing valve and the valve are of an integrated structure, when the valve is used for a certain time, a sealing structure can deform due to long-term contact with the valve clack, and therefore a worker needs to replace the whole valve or a valve body.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an adopt can dismantle seal structure's valve to solve in the current valve density structure and the valve structure as an organic whole with the valve clack contact, when the valve used for a certain time, seal structure can be because of the deformation with the long-term contact of valve clack, so the staff need change the problem of whole valve or valve body.

In order to achieve the above purpose, the present invention is realized by the following technical solution: the utility model provides an adopt valve that can dismantle seal structure, its structure includes valve body, seal structure locates inside the valve body, seal structure includes sealing washer, link, draw-in groove, spacing groove, the link upper end is located and structure as an organic whole to the sealing washer, the inboard bottom of sealing washer is located to the draw-in groove, the inboard upper portion of sealing washer is located to the spacing groove, the spacing groove links to each other with the draw-in groove, the link outer lane is equipped with the screw thread to adopt the mode of thread tightening to be connected with the valve body.

Further, the top of the valve body is provided with an assembly opening, and the inner diameter of the assembly opening is larger than the outer diameter of the sealing ring.

Furthermore, the limiting groove is of a trapezoidal structure.

The utility model has the advantages that: the detachable sealing structure is adopted inside the valve, workers only need to replace the sealing structure regularly, the whole valve or the valve body does not need to be replaced, the cost is effectively reduced, the service life of the valve is prolonged, the rubber sealing ring can be assembled on the inner ring of the detachable sealing structure, and the sealing performance is greatly improved.

Drawings

Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

fig. 1 is a schematic sectional view of a valve with a detachable sealing structure according to the present invention;

fig. 2 is a detailed schematic structural diagram of a sealing structure of the present invention.

In the figure: the valve comprises a valve body-1, a sealing structure-2, a sealing ring-201, a connecting end-202, a clamping groove-203 and a limiting groove-204.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 and 2, the present invention provides a valve with a detachable sealing structure, which comprises: its structure includes valve body 1, seal structure 2 locates 1 insidely of valve body, seal structure 2 includes sealing washer 201, link 202, draw-in groove 203, spacing groove 204, sealing washer 201 is located 202 upper ends of link and structure as an organic whole, the inboard bottom of sealing washer 201 is located to draw-in groove 203, the inboard upper portion of sealing washer 201 is located to spacing groove 204, spacing groove 204 links to each other with draw-in groove 203, link 202 outer lane is equipped with the screw thread to be connected with 1 mode that adopts the thread tightening of valve body, 1 top of valve body is equipped with the assembly mouth, the internal diameter of assembly mouth is greater than the sealing washer 201 external diameter, spacing groove 204 is the trapezium structure.

For example, when using, work along with valve adjusting medium goes on, the valve clack can take place the contact with seal structure 2, draw-in groove 203 on the sealing washer 201 can be used to assemble rubber O type sealing washer, the outer lane of rubber O type sealing washer can be joined in marriage into spacing groove 204 and fix, when the valve uses when a certain time, can unpack the valve apart, staff's hand or apparatus stretch into through the assembly opening at 1 top of valve body, rotate seal structure 2, link 202 on the seal structure 2 can be unscrewed valve body 1, break away from with valve body 1 and be connected, later can take out seal structure 2 through the assembly opening, then more new seal structure 2, the valve can continue to use, effectual improvement life.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
