Description

Technical Field

[0001] The utility model relates to the technical field of valve protection, in particular to a valve stem protection device. Background Art

[0002] The existing low-position installation of ball valves is an objective choice. Currently, there is no specific, simple and feasible solution for the subjective behavior of operators such as kicking and pedaling. The main disadvantages are as follows:

[0003] (1) Accelerated equipment damage: Operators may habitually kick or push the ball valve stem to open and close the ball valve when starting or stopping work. The magnitude and direction of the force applied to the valve stem are often sudden and lack protection, which can easily cause deformation and aging of the ball valve stem, loosening of the ball valve fixing nut, loosening of the gasket seal, etc., leading to gas leakage at the ball valve position. If there are multiple ball valves at the gas consumption site, it is easy to form the possibility of multiple ball valve positions having hidden dangers at the same time, forming a large potential gas leakage hazard, endangering the lives and property of on-site personnel.

[0004] (2) Increase in enterprise operation and maintenance costs: The existing technical shortcomings will obviously increase the probability of gas leakage at the ball valve at the gas point, which is equivalent to increasing the workload, work frequency, and even work difficulty of the gas safety inspection and maintenance personnel at the site; for the users themselves, it will also obviously increase the cost of equipment updates.
