Problems solved by technology

[0003] The traditional flow valve is often composed of a manual adjustment valve group and an automatic balance valve group. The function of the manual adjustment valve group is to set the flow rate. Since the traditional manual adjustment valve group can only perform a single adjustment, the flow control valve Regulatory effect is limited

Abstract

The invention belongs to the technical field of control valves, and is specifically a composite hydraulic flow control valve, which includes a control valve body. An inlet pipe and an outlet pipe are arranged on both sides of the control valve body; an input pipe is arranged at the end of the inlet pipe. Pipe, the end of the inlet pipe and the input pipe is provided with a fixed ring, and a locking ring is provided between the two fixed rings; the locking ring is provided with a chute, and the chute is connected to a Magnets, the inner wall of the locking ring is provided with a No. 1 adjustment plate and a No. 2 adjustment plate, and the two adjustment plates are provided with adjustment grooves, and the side of the No. 2 adjustment plate is provided with a No. 2 magnet; the present invention By setting a locking ring on one side of the control valve body, the adjustment mechanism inside the locking ring can be replaced and repaired more conveniently and quickly. At the same time, the accuracy of flow control valve adjustment can be increased through two composite manual adjustment groups. Performance and flexibility, improve the working quality and service life of the flow control valve.

Description

technical field [0001] The invention belongs to the technical field of control valves, in particular to a composite hydraulic flow control valve. Background technique [0002] Flow control valves are used to control the speed of actuators. According to their functions and uses, they can be divided into throttle valves, stroke throttle valves, speed regulating valves, and split-flow throttle valves. Their common feature is to adjust the liquid resistance when the oil flows through the orifice by changing the flow area of ​​the orifice in the valve, so as to realize the control of the flow rate, and the flow control valve relies on A valve that changes the size of the orifice's fluid resistance to control the flow of the orifice, thereby adjusting the movement speed of the actuator, such as a hydraulic cylinder or a hydraulic motor. [0003] The traditional flow valve is often composed of a manual adjustment valve group and an automatic balance valve group. The function of th...
