Problems solved by technology

[0002] Sealing devices are widely used, especially in the joints of liquid pipelines, oil, liquid, pump valves must use sealing devices, the role of sealing devices It is to make the pipeline achieve effective sealing and achieve zero leakage. Traditional sealing materials are mostly rubber materials, but in some harsh environments, such as high pressure in boiler pipes, and reactors in other chemical industries, the sealing of reaction devices is due to high temperature.

Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0020] see figure 1 , the embodiment of the present invention includes:

[0021] The alloy sealing ring, the outermost layer is a fluoroplastic sealing sleeve, the middle part is an intermediate fixed shaft, the intermediate fixed shaft is connected to a copper metal bracket, the copper metal bracket is in the shape of a cross, and the copper metal bracket is To further support the alloy sealing ring, preferably, the copper metal bracket can also be replaced with a cross rib.

[0022] The fluoroplastic sealing sleeve is the main body of the alloy sealing ring. The fluoroplastic sealing sleeve is made of fluoroplastic, which is corrosion resistan...

Abstract

The invention discloses an alloy sealing ring. A fluoroplastic sealing cartridge is arranged on the outmost layer, a middle fixing shaft is arranged in the middle and is connected with a cross-shaped copper support, the copper support is filled with a filler layer, aluminum alloy supporting protrusions are connected to the outer side of the filler layer, and meanwhile, sealing ring flange connecting holes are formed in the periphery of the fluoroplastic sealing cartridge. The alloy sealing ring is high in abrasion resistance, high in corrosion resistance, reasonable in structure and high in strength.

Description

technical field [0001] The invention relates to the field of sealing devices, in particular to an alloy sealing ring. Background technique [0002] Sealing devices are widely used, especially at the joints of liquid pipelines, oil, liquid and pump valves must use sealing devices. The function of sealing devices is to make the pipelines effectively sealed and achieve zero leakage. Traditional sealing Most of the materials are rubber materials, but in some harsh environments, such as the high pressure of boiler pipes, and reaction kettles in other chemical industries, the sealing of reaction devices is not effective due to high temperature and high pressure, and the sealing effect of ordinary gaskets is not good. The sealing ring, due to the thermal expansion and contraction of the thermal stress, will cause the sealing ring to shrink and deform, and it will also cause the problem of poor sealing when used for a long time. [0003] Therefore, the invention provides an alloy ...
