Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve technology, specifically a two-way self-feedback hydraulic control valve. Background Technology

[0002] Hydraulic control valves are components in hydraulic transmission or control systems used to control the pressure, flow rate, and direction of liquid. Those controlling pressure are called pressure control valves, those controlling flow rate are called flow control valves, and those controlling on / off states and flow direction are called directional control valves. Most hydraulic control valves lack the ability to detect the oil flow rate during use, resulting in untimely feedback and making adjustments difficult based on usage. Furthermore, their mostly sealed structure makes subsequent disassembly and assembly very inconvenient. Therefore, we propose a two-way self-feedback hydraulic control valve. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a two-way self-feedback hydraulic control valve. The flow sensor can detect the flow rate of the oil and feed the detected data back to the controller in real time via a wireless transmitter, so that personnel can adjust the flow in a timely manner. At the same time, the locking bracket and locking groove can be locked together to facilitate the disassembly and assembly of the valve cover for subsequent maintenance, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a two-way self-feedback hydraulic control valve, including a valve body and an adjusting plate;

[0005] Valve housing: An oil chamber is provided inside the valve housing. A valve cover is installed on the right side of the valve housing.

This makes it easy to disassemble and install the valve cover 4 for subsequent cleaning, maintenance and replacement. The oil enters through the middle oil inlet 11, causing the spring inside the valve core 7 to contract. The oil can then be discharged through the right oil inlet 11. When the hydraulic oil enters through the left oil inlet 11, the hydraulic oil pushes the adjusting plate 9 to slide inside the oil chamber 8. The push rod 10 squeezes the valve core 7 to contract the spring. The oil can then enter through the right oil inlet 11 and be discharged through the middle oil inlet 11. The flow sensor 22 can detect the flow rate of the oil, and with the wireless transmitter 24, the flow data can be fed back to the technicians in real time for viewing, so as to facilitate subsequent adjustment. The filter screen 17 inside the fixed shell 21 can filter impurities in the oil to prevent impurities from entering the oil chamber 8. With the anti-corrosion coating 18, the service life of the control valve can be effectively increased.
