CN-121993639-A - Anti-corrosion structure of corrugated pipe of glasses valve

Abstract

The invention provides an anti-corrosion structure of a corrugated pipe of a glasses valve, which comprises a telescopic body and a corrugated pipe, wherein a circular ring I and a circular ring II are welded on the inner side of the telescopic body, a guide cylinder is welded on the circular ring I, a packing is embedded on the circular ring II and is abutted with the guide cylinder, and anti-corrosion coatings are sprayed on the inner side of the corrugated pipe, each welding seam and the inner channel surface of the telescopic body. Through ring II, draft tube and packing, avoid having corrosive comdenstion water to accumulate in the bellows inboard, corrosion-resistant coating also can effectually delay the corrosion of bellows and flexible internal side welding seam simultaneously, prolongs the life of valve.

Description

Anti-corrosion structure of corrugated pipe of glasses valve Technical Field The invention relates to the technical field of eyeglass valves, in particular to an anti-corrosion structure of an eyeglass valve corrugated pipe. Background In the practical use process of the conventional glasses valve, because water vapor in the gas has strong corrosiveness, after the water vapor is condensed, the water vapor is accumulated in the lower half part of the inner channel of the valve, so that the cylinder body, the corrugated pipe, the welding seam and the like of the glasses valve are corroded and penetrated, the gas is leaked, and the safety cannot be ensured. The conventional anti-corrosion technology can only carry out anti-corrosion on the inner channel of the valve, but the corrugated pipe and the welding seam between the corrugated pipe and the telescopic body cannot be effectively subjected to anti-corrosion treatment, so that the service life of the valve is greatly shortened. Disclosure of Invention Aiming at the defects of the prior art, the invention provides an anti-corrosion structure of a corrugated pipe of a glasses valve, which comprises a telescopic body and a corrugated pipe, wherein a circular ring I and a circular ring II are welded on the inner side of the telescopic body, a guide cylinder is welded on the circular ring I, an oil-immersed graphite packing is embedded on the circular ring II, the packing is abutted with the guide cylinder, and elastic anti-corrosion coatings are sprayed on the inner side of the corrugated pipe, each welding seam and the inner channel surface of the telescopic body. Preferably, the telescopic body and the circular ring II are made of carbon steel. Preferably, the circular ring I and the guide cylinder are made of stainless steel. Advantageous effects Through ring II, draft tube and packing, avoid having corrosive comdenstion water to accumulate in the bellows inboard, corrosion-resistant coating also can effectually delay the corrosion of bellows and flexible internal side welding seam simultaneously, prolongs the life of valve. Drawings FIG. 1 is a schematic diagram of the structure of the present invention. In the figure, the telescopic body is 1, the circular ring I is 2, the guide cylinder is 3, the circular ring II is 4, the oil immersed graphite packing is 5, and the corrugated pipe is 6. Detailed Description The following description of the embodiments of the present invention 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 invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention. Referring to fig. 1, an anti-corrosion structure of a corrugated pipe of a glasses valve comprises a telescopic body and a corrugated pipe, wherein a circular ring I and a circular ring II are welded on the inner side of the telescopic body, a guide cylinder is welded on the circular ring I, the telescopic body and the circular ring II are made of carbon steel, the circular ring I and the guide cylinder are made of stainless steel, an oil-immersed graphite packing is embedded on the circular ring II and is abutted to the guide cylinder, and an elastic anti-corrosion coating is sprayed on the inner side of the corrugated pipe, each welding seam and the inner channel surface of the telescopic body. Through ring II, draft tube and oily graphite packing, avoid having corrosive comdenstion water to accumulate in the bellows inboard, the corrosion of bellows and flexible internal side welding seam also can effectually be delayed to the elastic anti-corrosion coating simultaneously, prolongs the life of valve.
