Abstract
The utility model discloses a VCR pipe connecting sealing gasket which is applied to a high-concentration air supply system. The VCR pipe connecting sealing gasket comprises a metal gasket main body, and a protection cover made of a polytetrafluoroethylene material is arranged on the lower surface of the gasket main body. The protection cover is fixedly connected with a thick wall of the gasket main body, a cavity is arranged between the protection cover and the lower surface of the gasket main body, and a seal ring made of a rubber material is arranged in the cavity. The protection cover made of polytetrafluoroethylene is good in chemical stability and sealing performance, the rubber seal ring is protected through the protection cover, so that the seal ring is not in contact with the outside easily, elasticity of the sealing gasket is improved, and the sealing gasket is good in sealing performance and long in service life.
Description
Technical field
The utility model relates to a kind of gasket seal, is specifically related on a kind of VCR of being applicable to pipeline the gasket seal for gas seal.
Background technique
In the laboratory of Liquid crystal production enterprise, can carry out various tests to product, generally can set up corresponding air supply system and be used to provide various gas.Owing to often can being full of such as toxic and harmfuls such as hydrogen bromide ammonias in air supply system, therefore, the leak-down rate of air supply system is had to strict requirement, such as: corrosion resistance, compression resistance, sealing etc.Pad conventional on market cannot be suitable for such environment, and its working life is also lower.
Model utility content
For solving the problems of the technologies described above, we have proposed a kind of VCR sealing for tubing joints pad, its objective is a kind of gasket seal that is applicable to air supply system, good airproof performance, long service life is provided.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of VCR sealing for tubing joints pad; be applied in high concentration air supply system; comprise metallic shim main body; on described gasket body lower surface, be provided with the protecting jacket of being made by polytetrafluoroethylmaterial material; described protecting jacket is fixedly connected with the wall thickness of described gasket body; and between described protecting jacket and described gasket body lower surface, be provided with cavity, in described cavity, be provided with the seal ring of being made by rubber material.
Preferably, described protecting jacket is 45 degree near the corner angle angle of interior ring one side margin.
Preferably, the pad that the stainless steel material that described gasket body is American Standard 316L by material is made.
Pass through technique scheme; the beneficial effect that the utility model is obtained is: the chemical stability of the protecting jacket of making by teflon itself is relatively good; concrete well sealing; by its protection rubber seal ring; make seal ring be difficult for contacting with extraneous; increase the elasticity of gasket seal, make the good seal performance of gasket seal, the life-span is long.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the cross-sectional schematic of the disclosed a kind of VCR sealing for tubing joints pad of the utility model embodiment.
Numeral and the represented corresponding part title of letter in figure:
1. gasket body 2. protecting jacket 3. seal rings.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of VCR sealing for tubing joints pad; its working principle is: the chemical stability of the protecting jacket of making by teflon itself is relatively good; concrete well sealing; by its protection rubber seal ring; make seal ring be difficult for contacting with extraneous; increase the elasticity of gasket seal, make the good seal performance of gasket seal, the life-span is long.
Below in conjunction with embodiment and embodiment, the utility model is described in further detail.
Embodiment.
As shown in Figure 1; a kind of VCR sealing for tubing joints pad; be applied in high concentration air supply system; comprise metallic shim main body 1; on described gasket body 1 lower surface, be provided with the protecting jacket 2 of being made by polytetrafluoroethylmaterial material; described protecting jacket 2 is fixedly connected with the wall thickness of described gasket body 1, and is provided with cavity between described protecting jacket 2 and described gasket body 1 lower surface, is provided with the seal ring 3 of being made by rubber material in described cavity.In the present embodiment, described protecting jacket 2 is 45 degree near the corner angle angle of interior ring one side margin; The pad that the stainless steel material that described gasket body 1 is American Standard 316L by material is made.
Above-described is only the preferred implementation of a kind of VCR sealing for tubing joints of the utility model pad; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (3)
