Integrated switching three-way valve

Abstract

The invention relates to the technical field of valves, in particular to an integrated switching three-way valve which comprises a valve body. Two flow guide pipes are symmetrically arranged at the lower end of the valve body, connecting pipes are installed outside the two flow guide pipes, and a driving mechanism matched with fluid and used for providing power is arranged in the valve body. Sealing mechanisms which are matched with the driving mechanism and are used for improving the sealing performance between the flow guide pipes and the connecting pipes are arranged at the outlets of the two flow guide pipes. According to the integrated switching three-way valve, fluid in the valve body drives a power generation equipment body to generate current, so that magnetorheological fluid senses a magnetic field of an annular coil and shows the characteristics of non-Newtonian fluid, the sealing performance between the flow guide pipes and the connecting pipes is improved, the stability of connection between a clamping plate and an annular fixing plate is improved through extension of a magnetostrictive rod, and when the valve body leaks, an alarm body is driven to give an alarm, so that an operator is reminded to maintain the valve body in time.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an integrated switching three-way valve. Background technique [0002] The three-way valve refers to a valve device with three ports in the valve body, one in and two out. The three-way valve is divided into a confluence valve and a diversion valve according to the fluid action mode. The diverter valve has a fluid inlet, which flows out from two fluid outlets after diversion. [0003] The existing patent (notification number: CN107366777A) is an integrated switching three-way valve, including a casing nut, a gland, a positioning pin, a cap nut and a rotating slide valve housing, and the rotating slide valve housing is provided with a power oil inlet. , The oil supply and discharge ports of forward and reverse oil motors, the power oil inlet, the oil supply and discharge ports of forward and reverse oil motors, and the oil discharge ports are all welded with threaded joints, and t...

AI Technical Summary

Problems solved by technology

[0004] In this invention, the slide valve and the sleeve are relatively rotated to switch, and at the same time, two position signs are designed and limited when the valve is switched, so as to prevent human judgment errors and mechanical or electro-hydraulic uncertain states. The size of the first oil port is consistent with the size of the existing ship interface, and three oil ports are reduced at the same time, thereby reducing the leakage point of the system. The invention reduces the leakage by setting the size of the three-way valve, but it lacks active reduction. The leaking device of the valve body cannot remind the operator in time after the valve body leaks
