Abstract

The invention relates to the technical field of valve manufacturing, in particular to a plastic valve and a processing and manufacturing method thereof. The plastic valve comprises a valve body, wherein a main valve cavity is formed in the middle of the valve body, and two sides of the main valve cavity are communicated and matched with conveying pipelines to be mounted on two sides; an insertinground cavity communicating with the main valve cavity is formed in the portion, at the top of the main valve cavity, of the valve body, a main ball valve assembly and an auxiliary valve assembly are mounted in the main valve cavity, and the main ball valve assembly is used for achieving intercepting sealing in the normal pressure state. The main ball valve assembly and the auxiliary valve assemblyare matched to achieve intercepting sealing in a high pressure state. According to the plastic valve, by adopting the structure of the main valve element and the auxiliary valve element, double-effect sealing in the high-pressure state can be achieved through adjustment of the main valve element and the auxiliary valve element, so that the sealing effect is good, the overall structure is small, the main valve element and the auxiliary valve element are tightly matched, and therefore, the more effective sealing and intercepting effect is achieved.

Description

Technical field[0001]The invention relates to the technical field of valve manufacturing, in particular to a plastic valve and a manufacturing method thereof.Background technique[0002]Valves are pipeline accessories used to open and close pipelines, control flow, 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 the functions of cut-off, regulation, diversion, prevention of reverse flow, stabilization, diversion or overflow and 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. Because the plastic valve has the characteristics of corrosion resistance, oxidation resistance, so in ...
