Problems solved by technology

[0002] Stainless steel globe valve is an indispensable product widely used in industrial production and people's life, but in the process of use, due to acid and alkali corrosion, high temperature and low temperature, high pressure and long-term wear and tear, it will cause air leakage and liquid leakage. , if the stop valve is replaced with a new one, it will inevitably cause waste, and the cost of production and living will increase. If it is not replaced, it will cause waste of air leakage and liquid leakage. If it is repaired, it will cause damage to the stop valve and reduce its service life.

Abstract

An anti-inner-leakage device for a stainless steel stop valve is characterized by being formed by a stainless steel stop valve and a polytetrafluoroethylene plate. Due to the fact that a scrapped stainless steel stop valve with liquid leakage and gas leakage caused by an abraded face of the stop valve is adopted, and the technology that the polytetrafluoroethylene plate is added in the stop valve is adopted, the scrapped stainless steel stop valve recovers to be qualified. The scrapped stainless steel stop valve recovering to be qualified is good in use performance, free of gas leakage and liquid leakage and long in service life, improves valve utilization rate, and reduces the damage rate.

Description

(1) Technical field [0001] The invention belongs to a valve internal leakage prevention device, in particular to a stainless steel cut-off valve internal leakage prevention device (2) Background technology [0002] Stainless steel globe valve is an indispensable product widely used in industrial production and people's life, but in the process of use, due to acid and alkali corrosion, high temperature and low temperature, high pressure and long-term wear and tear, it will cause air leakage and liquid leakage. , If the stop valve is replaced with a new one, it will inevitably cause waste, and the cost of production and living will increase. If it is not replaced, it will cause waste of air leakage and liquid leakage. (3) Contents of the invention [0003] problem to be solved [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a stainless steel cut-off valve with long service life, corrosion resistance, high and lo...
