CN202674449U - Anticorrosive valve - Google Patents

Abstract

The utility model discloses an anticorrosive valve, which comprises a valve body, a plated and welded layer and a polytetrafluoroethylene anticorrosive layer, wherein the plated and welded layer is positioned on the inner wall of the valve body; the polytetrafluoroethylene anticorrosive layer is positioned outside the plated and welded layer and the valve body; and an anticorrosive alloy of the plated and welded layer adopts an ERNiCrMo-3 material. The plated and welded layer and polytetrafluoroethylene are used for forming double-layer protection, so that the safety of the valve body can be well ensured, and the normal work of the valve body can be ensured. The anticorrosive valve is simple in structure, and has high practical value.

Description

A kind of corrosion protection valve

Technical field

The utility model belongs to the circulation duct valve field, relates in particular to a kind of corrosion protection valve.

Background technique

In chemical industry, especially in the production of liquid chemicals, chemical product is often by realizing the transportation of production line, be unable to do without the practicality of valve in delivering pipe, existing valve mostly is metal-made, and the anticorrosive measure of employing just lays a coat of paint on the surface, be difficult to reach etch-proof purpose, time one is long, and valve still stops up, can not be normally practical.

Summary of the invention

The purpose of this utility model is to utilize at a kind of corrosion protection valve, is intended to solve that existing valve exists is difficult to reach the corrosion-resistant purpose, and the duplicate protection by plating layer and anticorrosive PTFE layer reaches the corrosion-resistant purpose.

The purpose of this utility model is to provide a kind of corrosion protection valve, and described corrosion protection valve comprises valve body, plating layer, anticorrosive PTFE layer;

The plating layer is positioned at the inwall of valve body, and the anticorrosive PTFE layer is positioned at the outside and the valve body outside of plating layer.

Further, described plating layer is attached to the inwall of valve body by the plating weldering.

The utility model adopts plating layer and teflon double shielding, can well guarantee the Security of valve body, makes its corrosion of avoiding acidic chemical, guarantees the normal operation of valve body, and the utility model is simple in structure, and good use value is arranged.
