Description

Vacuum-resistant fluorine-lined valve

Technical Field

The utility model relates to the technical field of fluorine-lined valves, in particular to an anti-vacuum fluorine-lined valve.

Background

The fluorine-lined valve is also called fluoroplastic lining corrosion-resistant valve, and is characterized by that polytetrafluoroethylene resin (or its sectional material is processed) is placed on the inner wall of steel or iron valve pressure-bearing piece (the same method is applicable to lining of various pressure containers and pipeline accessories) or on the outer surface of valve internal piece by adopting mould pressing (or inlaid) method, and its unique property in the aspect of resisting strong corrosion medium can be used for making various valves and pressure containers. Polytetrafluoroethylene is commonly called as "plastic king", which is produced by duponco et al, LTD was first developed and developed in 1938, and industrial production was carried out in 1949, and from the industrial application point of view, it has been a history of 50 years, but the time for actually widely applying the polytetrafluoroethylene in the valve industry is not long. In the corrosion-resistant material, polytetrafluoroethylene has incomparable excellent performance, besides molten alkali metal, elemental fluorine and aromatic hydrocarbon, the polytetrafluoroethylene is lined on the inner wall of the valve in the following reaction among hydrochloric acid, sulfuric acid, nitric acid, aqua regia, organic acid, strong oxidant, concentrated and diluted acid alternation, alkali alternation and various organic solvents with various concentrations, so that the defect of low strength of the polytetrafluoroethylene material is overcome, and the defects of poor corrosion resistance and high cost of the valve main body material are overcome. The fluorine lining valve is divided into: pinch valves, lined diaphragm valves, lined pneumatic butterfly valves, lined pneumatic ball valves, lined check valves, lined fluorine shut-off valves, lined plug valves, lined wedge gate valves, diaphragm valves, and the like

When the existing most industrial fluorine-lined valves are used, liquid is conveyed into the valves by an external pump and then is led into other equipment, and as the fluid in the industrial pipeline has some insoluble impurities and the valves lack of a filtering mechanism, the impurities are easily adsorbed on the inner walls of the valves, and the valves are blocked after long-term use, so that the normal use of the valves is affected.
