Thermal-insulation sleeve of anti-leakage pipeline valve

Abstract

The invention discloses a thermal-insulation sleeve of an anti-leakage pipeline valve. The thermal-insulation sleeve comprises an inlet end, a sealing pad and a dustproof room, wherein a sealing ringis mounted on the outer wall of the inlet end; the top of the sealing ring is connected with the thermal-insulation sleeve; a filter screen is fixedly arranged on the inner wall of the inlet end; a connecting block is mounted at the outer side of the filter screen; the sealing pad is positioned at the left end of the inlet end; a sealing body is arranged at the inner side of the sealing pad; a valve rod is mounted on the top of the sealing body; a hand wheel is mounted at the top end of the valve rod; the inner wall of the hand wheel is connected with a connecting rod; the left side of the connecting rod is equipped with a fixed disc; the dustproof room is positioned on the top of the sealing body; and a dustproof cover is fixedly arranged at the top end of the dustproof room. The thermal-insulation sleeve of the anti-leakage pipeline valve is equipped with the inlet end, the inner wall of the inlet end fits to the outer side of the filter screen, and the filter screen can filter solidparticles contained in substances which pass through a pipeline, so that the solid particles are prevented from damaging the device.

Description

technical field [0001] The invention relates to the technical field of pipeline valve devices, in particular to a leakage-proof pipeline valve insulation sleeve. Background technique [0002] Pipeline valves are devices used to control the direction, pressure, and flow of fluids in fluid systems. Pipeline valves are devices that enable or stop the flow of media (liquid, gas, powder) in piping and equipment and control their flow. The valve is a control component in the pipeline fluid delivery system. The sealing performance of the pipeline valve directly affects the performance and convenience of use. [0003] During the use of pipeline valve insulation sleeves on the market, the sealing performance is weak and easy to leak, which brings inconvenience to the device when it is working, and the insulation effect is not obvious, causing damage to the pipeline. Therefore, we propose a leak-proof pipeline valve insulation set. Contents of the invention [0004] The purpose of...
