A high-sealing and corrosion-resistant valve assembly and its manufacturing method

Abstract

The invention discloses a valve assembly with high sealing and corrosion resistance and a manufacturing method thereof, relates to the technical field of valves, and solves the problem that the existing valves are connected and fixed by using flanges, which are prone to leakage and the internal pressure of the valve When it is too large, pressure relief cannot be performed, and there is a problem of potential safety hazard. A highly sealed and corrosion-resistant valve assembly and a manufacturing method thereof, comprising a valve main body, a valve body main channel is arranged inside the valve main body, a valve core fixing rod support frame base is installed above the valve main body, and the valve body A valve core fixed rod support frame is installed on the upper surface of the core fixed rod support frame base, and a valve core fixed rod is installed in the middle of the valve core fixed rod support frame. The present invention is equipped with an emergency pressure relief mechanism, a sealing connection mechanism and a transfer pipe to perform emergency diversion or pressure relief when the internal flow or pressure of the valve is too large, so as to ensure the internal stability of the pipeline without accidents, simple structure and convenient operation. .

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a highly sealed and corrosion-resistant valve assembly and a manufacturing method thereof. Background technique [0002] With the rapid development of social economy, valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium, and are control components in the fluid conveying system. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are also divided into cast iron valves and cast iron valves according to their materials. Steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard custom-made valves, etc. Machinery Parts. [0003] However, the existing valves are connected ...
