Pressure detection device of hydraulic valve

Abstract

The present invention discloses pressure detection equipment that comprises a hydraulic valve body; a liquid inlet cavity with a rightward opening is formed in the hydraulic valve body, a screw cavity is formed in the lower wall of the liquid inlet cavity in a communicating mode, and an internal thread cavity extending upwards into the liquid inlet cavity is connected to the screw cavity in an up-down sliding mode; a telescopic box is fixedly connected to the left end face of the internal thread cavity, a telescopic cavity is formed in the telescopic box, a water tank is fixedly connected to the upper end face of the telescopic box, a water storage cavity with an upward opening is formed in the water tank, and a piston type detection mechanism extending upwards into the liquid inlet cavity is arranged in the screw cavity; and the lower wall of the liquid inlet cavity communicates with a communicating cavity located on the left side of the screw rod cavity. In the invention, the sealing performance of the valve element is detected in a water circulation mode, wherein the floating block is driven through the water level height after water circulation so as to make contact with the contact switch, and when the sealing performance of the valve element is poor and leakage is generated, a channel can be temporarily closed.

Description

technical field [0001] The invention relates to the related fields of hydraulic valves, in particular to pressure detection equipment for hydraulic valves. Background technique [0002] In industrial production and processing, a lot of equipment needs to use hydraulic devices, and most places with hydraulic devices are equipped with hydraulic valves for control. The performance of hydraulic valves determines the use effect of hydraulic devices. When the sealing of hydraulic valves When it is not good, it is easy to cause liquid leakage or even insufficient pressure. It is difficult for some existing hydraulic valve testing equipment to test the sealing performance of hydraulic valves, and the temporary remedial measures for liquid leakage are poor and difficult to meet the requirements of use. According to the needs, the present invention provides a pressure detection device for hydraulic valves, which can solve the above problems. Contents of the invention [0003] In or...
