A slide valve type one-way overflow valve

Abstract

The present invention relates to the field of relief valves, in particular to a slide valve type one-way relief valve, which comprises a rectangular casing, and a cover mechanism is arranged on the side wall of one side of the casing. A lane-changing mechanism is fixedly installed on the cover mechanism, and a water inlet pipe mechanism is fixedly connected to the upper surface of the casing, and a sealing mechanism is fixedly installed on the inner pipe wall of the end of the water inlet mechanism close to the casing, and the sealing mechanism There is an anti-separation mechanism inside, and the beneficial effect of the present invention is that when one of the receiving containers is full, the driving cylinder can be started to drive the piston rod to move, and the piston rod moves while driving the two sliding blocks to move synchronously, so that The outlet pipe corresponding to the filled liquid receiving container is closed, and at the same time another outlet pipe is opened to continue receiving, so as to prevent the overflow valve from being shut down during use and affect the subsequent use of the overflow valve.

Description

technical field [0001] The invention relates to the field of relief valves, in particular to a slide valve type one-way relief valve. Background technique [0002] The relief valve is a hydraulic pressure control valve, which mainly plays the role of constant pressure relief, pressure stabilization, system unloading and safety protection in hydraulic equipment. The damage of the ring, or the looseness of the mounting screws and pipe joints may cause unnecessary external leakage. [0003] For the relief valves used in chemical plants, there is usually only one pressure relief channel for some important relief valves. The receiving container is replaced, the use of the overflow valve will be affected during the replacement process, and the work efficiency will be reduced. Therefore, it is necessary to propose a slide valve type one-way overflow valve. Contents of the invention [0004] Aiming at the problems in the prior art, the present invention provides a slide valve ty...
