In order to achieve the above purpose, the present utility model provides the following technical solutions: a high-tightness pure-tetrafluoro modified plug sealing and punching gasket comprises a gasket body, wherein lips are fixed on two sides of the gasket body, and the two lips are symmetrically wrapped on the periphery of the gasket body.

Preferably, the gasket body is made of pure tetrafluoro material, and the gasket body is internally wrapped with a supporting sheet, the supporting sheet is of a net structure, and the supporting sheet is made of metal material.

Preferably, the two sides of the supporting sheet are both fixed with skirt edges, and the two skirt edges are symmetrically wrapped on the periphery of the supporting sheet.

Preferably, a buffer groove is formed between the two lips, and the buffer groove is distributed along the periphery of the gasket body.

Preferably, the outer periphery of the support sheet is captured within the lip.

Preferably, the gasket body is of a circular structure, and the middle part of the gasket body is provided with a mounting hole.

Compared with the prior art, the utility model has the beneficial effects that:

through the cooperation of gasket body and lip edge, make the sprint gasket when using, the lip edge of gasket body both sides can be forced and push down the part surface that is sealed, avoid high temperature corrosive fluid to flow out from the clearance of sprint gasket and part contact, effectual improvement the sealed effect of sprint gasket, be favorable to improving the sealing performance of pan-plug seal sprint gasket.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-6, embodiments of the present utility model are provided:

the utility model provides a pure tetrafluoro modified pan-plug seal sprint gasket of high leakproofness, including gasket body 1, gasket body 1 is circular structure, and the mounting hole has been seted up at gasket body 1's middle part to install gasket body 1 into the part, gasket body 1's both sides all are fixed with lip 2, and two lips 2 symmetry parcel are in gasket body 1's periphery, and it is worth mentioning, because gasket body 1 is widely used in the high temperature corrosive fluid's sealing place, consequently all adopts tetrafluoro material to constitute gasket body 1 and lip 2, because tetrafluoro material has excellent high low temperature resistant, low friction consumption, chemical corrosion resistant performance.

Further, as shown in fig. 3, in consideration of the fact that the gasket body 1 is subjected to a strong impact of fluid during use, in order to improve the structural strength of the gasket body 1, the gasket body 1 is internally wrapped with the supporting sheet 3, the supporting sheet 3 is in a net structure, and the supporting sheet 3 is made of a metal material.

As shown in fig. 4 and 5, considering that when fluid impacts the gasket body 1, the supporting plate 3 inside the gasket body 1 will also deform, in order to improve the stability of the supporting plate 3 when impacted, the skirts 4 are fixed on both sides of the supporting plate 3, and the two skirts 4 are symmetrically wrapped around the periphery of the supporting plate 3, and the periphery of the supporting plate 3 is clamped in the lip 2, so that when the gasket body 1 is impacted by fluid, the surface of the skirts 4 can be slowly pressed to the surface of the lip 2 to buffer the impact of the fluid, thereby improving the stability of the supporting plate 3 in the gasket body 1, and further improving the stability of the gasket body 1 when impacted by the fluid.

Further, as shown in fig. 5, in order to realize that the lips 2 can stably deform when being pressed by force, so as to tightly adhere the surfaces of the parts, buffer grooves 5 are formed between the two lips 2, and the buffer grooves 5 are distributed along the periphery of the gasket body 1, so that when the gasket body 1 works and fluid impacts, the two lips 2 can press the surfaces of the sealed parts in the direction of the buffer grooves 5, and the lips 2 can be better pressed against the surfaces of the sealed parts.

Working principle: when the gasket body 1 is installed in a part and then works, high-temperature corrosive fluid can impact the gasket body 1, at the moment, lips 2 on two sides of the periphery of the gasket body 1 are stressed and extruded to deform, so that the surfaces of the lips 2 are tightly attached to the surfaces of the part, the fluid is prevented from flowing out of a gap between the gasket body 1 and the part, and meanwhile, supporting sheets 3 are wrapped in the gasket body 1, so that the structural strength of the gasket body 1 is further improved, and the gasket body 1 can work stably.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model 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.
