A hydraulic control valve for real-time detection of flow velocity

Abstract

The invention belongs to the field of hydraulic control valves, in particular to a hydraulic control valve for real-time detection of flow velocity. , a detection blade is fixedly installed on the outer side of the outer rotating sleeve, the two ends of the outer rotating sleeve penetrate through the side wall of the monitoring casing and are fixedly sleeved with a bidirectional signal transmitting head, and the monitoring casing is close to the position of the outer rotating sleeve The external fixing frame is fixedly installed. By arranging ratchet teeth on the outer side of the fixed shaft, and setting meshing teeth on the inner side of the outer rotating sleeve to mesh with the ratchet teeth, the outer rotating sleeve can only rotate clockwise relative to the fixed shaft, avoiding the situation of backflow and ensuring the smooth operation of the device. At the same time, it also prevents the counterclockwise rotation of the outer rotating sleeve when driving the rotation of the two-way signal transmitting head, which leads to the detection error of the sensing head, making the linkage between the structures more reliable and accurate.

Description

technical field [0001] The invention relates to the field of hydraulic control valves, in particular to a hydraulic control valve for real-time detection of flow velocity. Background technique [0002] Hydraulic control valve is a general term, a type of automatic control valve composed of a main valve and its external needle valve, guide valve, etc. The working state of hydraulic control valve is generally in the usual state, normally open state, floating state, It mainly depends on the adjustment between the main valve and the needle valve or pilot valve to control the water flow state. [0003] When the existing hydraulic control valve is in use, there is no function of detecting the flow rate, so that it is impossible to detect the water pressure and the water volume of the water storage tank according to the flow rate of the water flow, so that when in use, it is often necessary to judge by other devices. The amount of water is very troublesome. At the same time, the e...

AI Technical Summary

Problems solved by technology

[0003] When the existing hydraulic control valve is in use, there is no function of detecting the flow rate, which makes it impossible to detect the water pressure and the water volume of the water storage tank according to the flow rate of the water flow, so that it often needs to be judged by other devices when in use. The amount of water is very troublesome. At the same time, the existing device does not have a function of filtering, pressure relief, and dust removal, so that the particulate matter in the water flow is discharged to the water receiving position along with the water flow, thereby reducing the water quality and affecting the use. It is not conducive to the flow of water. transportation
