What is the role of the flow control valve in the flow control valve above the new amusement equipment? The flow control valve of the new amusement equipment adjusts the flow rate of the fluid flowing through the valve port by changing the flow cross-sectional area of the throttle valve to control the moving speed of the actuator, the speed of signal transmission or the length of time. The shape of the hole is various and can be divided into needle valve type, eccentric groove type, axial triangular groove type and axial slit type. These throttle ports use the spool to move axially or rotate about an axis to change valve flow. The size of the cross-sectional area to regulate the flow of pressurized fluid. The needle valve moves axially to the left and right and adjusts the size of the annular passage to regulate flow. Due to the long throttling length and hydraulic radius (the ratio of the flow area to the circumference of the orifice), it is easy to block, and the flow is greatly affected by the oil temperature, so it is rarely used at present. Eccentric grooved throttle valve. When the spool is turned, the size of the passage can be adjusted to regulate the flow. The picture shows the axial triangular groove throttle valve, when the spool moves axially, the flow of the triangular groove can be changed. This type of throttle valve is simple in shape, easy to manufacture and reliable in use, so it is used more. The flow control valve of the new amusement equipment adjusts the flow through the valve port by changing the size of the orifice, thereby adjusting the speed of the hydraulic cylinder and the speed of the hydraulic motor. When oil flows through a small hole or slit, hydraulic resistance is created, and a valve is created. The smaller the flow area of the mouth, the greater the resistance when the oil passes, the smaller the flow rate, and the lower the speed of the actuator. The structure of the throttling device of the new amusement equipment, the form of the throttling adopts the axial triangular groove pattern, the oil from the inlet enters the orifice 3 through the pressure pill and the throttling groove on the right end of the spool, and then flows out from the oil outlet. The rotary handle can be moved by a push rod, and the throttle opening opens when the left movement is made and closes when the displacement is correct, thereby regulating the flow rate through the valve. This new type of amusement equipment throttle valve has poor flow stability and is only suitable for hydraulic systems with little change in oil temperature and load.
