Rapid seal valve for cleaning steel tube

Abstract

The invention relates to a rapid seal valve for cleaning a steel tube. The rapid seal valve comprises a cylindrical valve body, one end of the cylindrical valve body is a steel tube connection port, the other end of the cylindrical valve body is a cleaning liquid inlet, a flexible air inflation pipe is arranged in an inner cavity of the cylindrical valve body, the inner wall of the flexible air inflation pipe can be in a seal connection with the steel tube after inflation, and an air inflation hole which is communicated with the flexible air inflation pipe is arranged on the cylindrical valve body. The steel tube enters in the cylindrical valve body from the steel tube connection port and inflates air into the flexible air inflation pipe when the steel tube reaches in place, the flexible air inflation pipe is in a seal connection with the steel tube under the action of air pressure, and accordingly, a cleaning liquid is fed from the cleaning liquid inlet for cleaning the steel tube. The rapid seal valve for cleaning the steel tube is simple in structure, easy to manufacture, simple in operation, high in efficiencies and capable of achieving rapid seal connection with the steel tube by inflating the air to the flexible air inflation pipe, and leakage problem of the cleaning liquid is absent.

Description

technical field [0001] The invention relates to a quick sealing valve for steel pipe cleaning. Background technique [0002] Stainless steel pipe is a hollow long strip of steel, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength is the same, the weight is lighter, so it is Widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, etc. Especially the high-precision stainless steel pipes used in the nuclear industry or power stations and other places do not allow a little water and oil on the inner and outer surfaces of the steel pipes, especially oil pollution has a greater impact on the steel pipes, and the steel pipes need to be degreased. [0003] When cleaning the inner wall of the steel pipe, the more effective cleaning method is to flush the degreasing li...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: to overcome the technical problems in the prior art that the washer and the steel pipe are not tightly sealed, causing leakage, complex operation and low efficiency when cleaning the steel pipe, and to provide a fast cleaning method for steel pipe The sealing valve can be quickly connected to the steel pipe, and the airtight connection with the steel pipe can be realized by inflating the flexible inflation tube. There is no leakage problem, the operation is simple, and the efficiency is high.
