Abstract

The invention discloses a valve protective cap which comprises a cap and a barrel body, wherein the cap covers the top of the barrel body; the barrel body is formed by fixedly connecting a set of barrel body pieces; the bottom of the barrel body is provided with a plurality of circular outlets; and the cap is fixedly connected with the barrel body. The valve protective cap plays roles of rust prevention and corrosion prevention because a valve is integrally protected in the protective cap and also prolongs the service life of the valve.

Description

technical field [0001] The invention relates to a protective cover, in particular to a valve protective cover capable of preventing rust and corrosion of pipeline valves. Background technique [0002] In the petrochemical industry, pipelines are controlled by various valves; since most of these valves are located in the open air, exposed to wind, sun, and rain, the valves are easy to corrode and rust, resulting in short service life of the valves. It is long and needs to be replaced frequently; due to the large volume of pipeline valves used in the petrochemical industry, it is necessary to stop the work of the pipeline when replacing, and the replacement procedure is complicated, which brings a lot of inconvenience to production. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to solve the deficiencies of the prior art and provide a valve guard that is easy to use and install, and can play an anti-corrosion and anti-rust role. ...
