Problems solved by technology

[0002] The water pipes currently used are all plastic pipes for liquid circulation. When a part of the water pipe breaks and leaks, the main switch needs to be turned off, and then the ruptured part should be repaired. After the main switch is turned off, a part of the water pipe will remain liquids, which also leak through the rupture site

Abstract

The invention discloses a vortex isolation control type stop pipe valve, and relates to the field of pipeline maintenance. The vortex isolation control type stop pipe valve comprises a main pipeline,an elastic inner core tube, a vortex heater and a temperature controller. A plurality of limiting ropes are uniformly and fixedly connected between the inner surface of the main pipeline and the outersurface of the elastic inner core pipe. Waterproof coatings are applied to the limiting ropes. A plurality of elastic partition plates are uniformly and fixedly connected to the inner surface of theelastic inner core pipe in the vertical direction. An expansion cavity is formed between every two up-and-down-adjacent elastic partition plates. Elastic balls with cavities inside the elastic balls are arranged in the expansion cavities. The vortex isolation control type stop pipe valve has the beneficial effects that the main pipeline can be quickly closed at any position, leakage of liquid in the main pipeline is alleviated, and unnecessary loss is reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline maintenance. Background technique [0002] The water pipes used now are all plastic pipes for liquid circulation. When a certain part of the water pipe breaks and leaks, the main switch needs to be turned off, and then the broken part needs to be repaired. After the main switch is turned off, a part of the water pipe will remain in the water pipe. liquids, which can also leak through the rupture site. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an isolation eddy current control type globe valve in view of the above-mentioned technical deficiencies. The main pipeline can be quickly closed at any position to reduce the leakage of liquid inside the main pipeline and reduce unnecessary losses. [0004] The technical scheme adopted in the present invention is to provide an isolation eddy current control type globe valve, comprising a ...
