Abstract

The invention discloses a combined type hydraulic flow control valve and relates to the technical field of flow control valves, the combined type hydraulic flow control valve comprises a valve body and a water inlet pipe, an adjusting valve plate is arranged on one side of a reference valve plate, a fine adjustment mechanism is arranged on one side of the valve body, and a coarse adjustment mechanism is arranged on the other side of the valve body; butt joint structures are arranged at the two ends of the water inlet pipe, the water inlet pipe is connected with the valve body through the butt joint structures, a flow monitoring mechanism is arranged on the inner wall of the water outlet pipe, and an impurity collecting assembly is arranged on the inner wall of the water inlet pipe. When liquid needs to be subjected to large-flow circulation, the rotating disc is rotated, the convex rod is observed to rotate by a certain angle, the flow of the liquid is the maximum when the convex rod rotates by 90 degrees, and the fine adjustment mechanism and the coarse adjustment mechanism are arranged on one valve at the same time, so that the valve body can meet high-precision adjustment of the flow through the fine adjustment mechanism; and rapid and large-flux adjustment control of the flow can be realized through the coarse adjustment mechanism, so that the applicability is improved.

Description

technical field [0001] The invention relates to the technical field of flow control valves, in particular to a compound hydraulic flow control valve. Background technique [0002] The flow control valve is used to control the speed of the actuator, by changing the flow area of ​​the orifice in the valve to adjust the liquid resistance when the oil flows through the orifice, so as to control the flow. Traditional flow valves often It consists of a manual regulating valve group and an automatic balancing valve group. The function of the manual regulating valve group is to set the flow. Since the traditional manual regulating valve group can only perform a single adjustment, the regulating effect of the flow control valve is limited. [0003] After searching, the Chinese invention publication number is: CN111322478B patent discloses a compound hydraulic flow control valve. It is convenient and quick to replace and maintain, and at the same time, it can also increase the accura...
