Visible safety valve

Abstract

The invention discloses a visual safety valve. The visual safety valve at least comprises a safety valve body and an indicating rod, the indicating rod can be arranged on the safety valve body in a mode of being driven by a valve element of the safety valve body in the set direction, so that opening and closing of the safety valve body are judged by observing the position of the indicating rod. Through the arrangement the indicating rod, the working state (opening / closing of the safety valve) of the visual safety valve can be conveniently checked, so that the safety of equipment operation is improved, the working intensity of workers for checking the working state of the visual safety valve is reduced, the structure is simple, and production and manufacturing are convenient, so that the production efficiency is improved, the production cost is reduced; and meanwhile, high compactness is achieved, so that space waste is avoided, and the weight of the visual safety valve is reduced.

Description

technical field [0001] The invention relates to the field of safety valves, in particular to a visible safety valve. Background technique [0002] Safety valves are mainly installed in pressure vessels, pipelines, boilers and other equipment. When the pressure in the equipment is too high, the safety valve will open to relieve pressure; the safety valve is often placed outside, but it is impossible to judge whether the safety valve is open. It makes it impossible for the inspectors to judge whether the equipment is working normally during the inspection, which will not only lead to misjudgment by the inspectors, but also cause safety risks, and also increase the work intensity of the inspectors during regular inspections; It is regarded as a safety valve, but its complex structure is not convenient for production and assembly, and its compactness is not high, which increases unnecessary space and waste of materials for parts. [0003] Therefore, in order to solve the above ...
