Description

Hydraulic control valve

Technical Field

The utility model relates to the technical field of valves, concretely relates to hydraulic control valve.

Background

The valve is a device for controlling fluid flow or blocking through the valve core, is arranged on a pipeline, can realize the flow of fluid in the pipeline, and is commonly used for material control and the like in water pipes and production.

In the chinese patent application No. CN201821645237.5, "water conservancy control valve", the control of the compression amount of the first spring can be realized by adjusting the adjusting nut, so as to control the opening pressure of the valve core, thus realizing the automatic opening and closing of the valve core, when the pressure of the water pressure on the valve core is greater than the elastic force of the first spring, the valve core is opened, otherwise, the valve core is not opened, on the other hand, when the opening and closing of the valve core is not required to be automatically controlled by the water pressure, the first spring is completely compressed by adjusting the adjusting nut, at this time, the first locking hole and the second locking hole are overlapped, the locking rod is rotated to extrude the locking pin, so that the locking pin is inserted into the first locking hole and the second locking hole, thereby locking the first sliding cylinder and the sliding sleeve, so that the first sliding cylinder and the sliding sleeve cannot slide relatively, thus the opening and closing of the valve core can be manually controlled;

however, among the prior art, traditional valve is in the closure back, can't observe inside whether sealed, if live time has been of a specified duration, the sealing washer is damaged, then causes sealed inefficacy easily, among the conventional art, uses the pressure gauge to detect mostly, and if the pressure of revealing is less, the pressure gauge can't detect out, is difficult to the problem of very first time discovery valve.
