Abstract

The invention discloses a sealing device of a gauge pipe valve part. The sealing device comprises a valve body. A pipeline is arranged in the middle in the valve body and is arranged horizontally. A valve element is arranged in the middle of the valve body and arranged vertically. A handle is arranged at the top end of the valve element. A sealing groove is arranged at the bottom end in the middleof the pipeline and is in an inverted trapezoid shape. The handle and the valve element are connected through a connecting rod. A sleeve rod is arranged in the middle in the valve element. A slidingcavity is arranged in the middle in the sleeve rod. The bottom of the connecting rod is located in the sliding cavity. Connecting plates are arranged on the two sides of the bottom end of the connecting rod. Second clamp blocks are arranged at the top ends of the connecting plates. Second clamp grooves matched with the second clamp blocks are arranged at the positions, located at the top end of the sliding cavity, of the tops of the second clamp blocks, and magnets are arranged in the second clamp grooves. A bearing is arranged at the bottom end of the sleeve rod, ejection blocks are symmetrically arranged on the two sides of the bottom end of the bearing, and sealing plugs are arranged on the two sides of the bottom of the sleeve rod.

Description

technical field [0001] The invention relates to the technical field of sealing devices, in particular to a sealing device for instrument pipe valve parts. Background technique [0002] Instrument pipe valve parts refer to some parts, joints and valves connected to instruments or valves on the gas pipeline. [0003] With the continuous improvement of people's living standards, natural gas is used more and more widely, but natural gas is a flammable and explosive gas. During the use of natural gas, both the delivery pipeline and the valves on the natural gas instrument pipe require extremely high sealing. Sex, with the development of science and technology, natural gas valves have developed to a great extent, and its development has brought great convenience to people when installing natural gas valves, and its types and quantities are also increasing day by day. At present, there are many types and quantities of natural gas valves on the market, but most of the natural gas v...
