Abstract

The invention relates to the technical field of valve manufacturing, in particular to a plastic valve and its manufacturing method, comprising a valve body, a main valve cavity is arranged in the middle of the valve body, both sides of the main valve cavity are connected with both sides The delivery pipelines to be installed are connected and matched, and a plug-in round cavity connected with it is provided on the valve body at the top of the main valve cavity, and a main ball valve assembly and a sub-valve are installed in the main valve cavity. Assemblies, the main ball valve assembly is used to realize the cut-off seal under normal pressure, the main ball valve assembly cooperates with the auxiliary disc valve assembly to realize the cut-off seal under high pressure state, the plastic valve adopts the structure of the main and auxiliary valve cores, The double-effect sealing under high pressure can be realized through the adjustment of the two valves, the sealing effect is good, the overall structure is compact, and the main and auxiliary valve cores are closely matched to achieve a more effective sealing and intercepting effect.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a plastic valve and a processing and manufacturing method thereof. Background technique [0002] 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. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. [0003] As a control component in the fluid delivery system, the valve has functions such as cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. [0004] In the process of conveying fluid, the valve will put forward different requirements on the conveying environment and the performance of the valve body material according to the nature and state of the conveying fluid. Since plastic valves have the characteris...
