Abstract

The invention provides a corrugated pipe valve structure. The corrugated pipe valve structure comprises a valve body, a valve cover in the vertical direction is arranged at the top end of the valve body, a valve rod is arranged in the valve cover, the valve rod is sleeved with a corrugated pipe assembly, the top end of the corrugated pipe assembly and the valve cover are welded and sealed, the bottom end of the corrugated pipe assembly and the valve rod are welded and sealed, and the top end of the valve rod extends out of the valve cover to be connected with a hand wheel. The corrugated pipe valve structure is good in sealing performance and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a bellows valve structure. Background technique [0002] With the enhancement of environmental protection awareness worldwide, people have higher and higher requirements for valve sealing, especially in special occasions such as nuclear installations and petroleum and chemical industries, requiring valves to achieve "zero leakage". The traditional bellows valve has many external leakage points, usually at least two, and the bellows has a short lifespan. SUMMARY OF THE INVENTION [0003] Therefore, the present invention solves the problem that the bellows valve has many external leakage points in the prior art, and the opening and closing position of the valve cannot be observed. [0004] To this end, the technical solution adopted is that the present invention provides a bellows valve structure, comprising: a valve body, the top of the valve body is provided with a vertical val...
