Anti-corrosive anti-pollution environment-friendly plastic brake valve with flexible seal and machining process thereof

Abstract

The invention discloses an anti-corrosive anti-pollution environment-friendly plastic brake valve with flexible seal, and solves the defects that in the prior art, the manufacturing process of a flexible seal brake valve is complicated, the manufacturing cost is high, and secondary pollution is easily caused for fluids. The plastic brake valve comprises a valve body, a valve cover, a valve rod and a brake plate, wherein the valve body is in a three-way structure; the valve cover is arranged at the top end of the valve body, and is movably connected with the valve body; one end of the valve rod penetrates through the valve cover and stretches to the inside of the valve body, and the other end of the valve rod is provided with an adjusting hand wheel; the brake plate is arranged at one end of the valve rod; the brake plate is a composite plastic brake plate; the valve body and the valve cover are both made of modified polyphenylene oxide; and copper connectors are arranged at two connecting ends of the valve body. On the basis, the invention further discloses a machining process of the anti-corrosive anti-pollution environment-friendly plastic brake valve with flexible seal. The anti-corrosive anti-pollution environment-friendly plastic brake valve with flexible seal disclosed by the invention has a simple structure, and can be conveniently machined through injection molding; therefore, the brake valve is suitable to be widely promoted and applied.

Description

technical field [0001] The invention relates to a gate valve, in particular to an anti-corrosion and anti-pollution type soft-sealed environment-friendly plastic gate valve and its processing technology. Background technique [0002] Gate valves are widely used in industry and daily life, especially in fluid transportation pipelines for opening and closing fluid transportation. As a common structure in gate valves, soft-sealed gate valves are more widely used in the field of water supply and drainage, such as valve components of tap water pipelines in daily life. The soft-sealed gate valve is mainly composed of a valve body, a bonnet and a gate plate; at present, the main parts of the soft-sealed gate valve on the market are basically made of metal materials such as cast iron. On the one hand, the valve body and bonnet are mainly made of cast iron. It is mainly completed by casting, grinding, sandblasting, machining, plastic spraying and other processes. There are many proc...
