Abstract

本实用新型公开了一种带楔形阀的磁流变液压锁,主要由楔形阀缸体、楔形阀芯、液压锁缸体、活塞、活塞杆及阀体等组成。液压泵系统向A腔供油,使其压强大于B腔,此时活塞向右运动至极限位置,活塞杆Ⅱ右端锥面将F腔封死,实现可靠锁紧。楔形阀芯Ⅰ由于重力作用始终与楔形阀芯Ⅱ楔面接触,磁流变液泵系统向G腔注入磁流变液,控制器向励磁线圈通电,磁流变液迅速变成类固态,堵塞磁流变液进油口,G腔压力升高,可持续阻断D腔与E腔的连接,使油液不能从进油口流入出油口,达到控制油井油液单向流动以及防喷目的。磁流变液泵系统工作时,液压泵系统停止工作。本实用新型结构简单、操作方便、耗能少,特别适合应用在油井防喷的场合。

The utility model discloses a magnetorheological hydraulic lock with a wedge valve, which is mainly composed of a wedge valve cylinder, a wedge valve core, a hydraulic lock cylinder, a piston, a piston rod, a valve body and the like. The hydraulic pump system supplies oil to the A cavity, making its pressure stronger than that of the B cavity. At this time, the piston moves to the right to the limit position, and the conical surface of the right end of the piston rod II seals the F cavity to achieve reliable locking. The wedge valve core I is always in contact with the wedge surface of the wedge valve core II due to the action of gravity. The magnetorheological fluid pump system injects the magnetorheological fluid into the G cavity. At the oil inlet of magnetorheological fluid, the pressure in the G cavity increases, which can continuously block the connection between the D cavity and the E cavity, so that the oil cannot flow from the oil inlet to the oil outlet, so as to control the unidirectional flow of oil in the oil well and prevent blowout. Purpose. When the magnetorheological fluid pump system is working, the hydraulic pump system stops working. The utility model has the advantages of simple structure, convenient operation and low energy consumption, and is especially suitable for application in the occasion of blowout prevention of oil wells.
