Problems solved by technology

[0003] A valve disclosed in the Chinese invention patent application publication specification CN105179718B, although the valve solves the defect that it is difficult to accurately test the leakage of the packing in the existing valve sealing performance level certification, the valve cannot be used as a good valve. Provide a reliable anti-leakage structure, and provide multiple sealing structures for the valve to enhance the sealing performance of the valve itself, which cannot well avoid the phenomenon that the valve is opened due to accidental touch by users or maintenance personnel. The user provides a detachable valve stem, which does not enhance the stability of the connection between the valve and external components.

Abstract

The invention discloses a valve with a removable valve rod of an anti-leakage structure, and relates to the technical field of valves. The valve with the removable valve rod of the anti-leakage structure comprises a valve body, a main rod and a force application mechanism; the right and left sides of the valve body are each provided with a threaded connecting rod, and the middle part of each threaded connecting rod is fixedly provided with a fixing block; the valve body is internally provided with an isolating mechanism, and a rubber bottom block is installed above the isolating mechanism; therubber bottom block is internally provided with a connecting block, and the middle part of the main rod is provided with a sealing mechanism; and the main rod is located above the rubber bottom block. The valve with the removable valve rod of the anti-leakage structure is provided with an air bag and a rubber layer, and air can be introduced into the air bag through an air pump; the air bag starts to inflate, so that the rubber layer is pushed for expansion, and the rubber layer, the valve body, the main rod and a top cover are fit closely; and thus, liquid leakage can be avoided effectively,and the sealing performance of the valve can be improved effectively.

Description

Technical field [0001] The invention relates to the technical field of valves, in particular to a valve with a detachable stem with an anti-leakage structure. Background technique [0002] Valves are the control components in the fluid conveying system. They have the functions of cut-off, regulation, diversion, prevention of backflow, voltage stabilization, diversion or overflow and pressure relief. They can be used for valves in fluid control systems, from the simplest cut-off valves to extremely complex The various valves used in the automatic control system of the company have many varieties and specifications. With the development of the social level, when the valve is used for liquid diversion, it also needs to have corresponding functions. At this time, you need a Valve with detachable stem with anti-leakage structure. [0003] A valve disclosed in the Chinese Invention Patent Application Publication CN105179718B. Although the valve solves the defect that it is difficult to ...
