Valve cylinders have reversing and/or throttling functions. It is compact in structure, easy to use, reduces pipe distribution, reduces installation hours, and saves space. The disadvantage is that the electromagnetic reversing valve cannot be centrally installed together, which is not conducive to management.
Depending on the valve, There are one-way throttle valves (CZ1, CJ2Z series), there are electromagnetic reversing valves (CVJ3, CVJ5 series), there are electromagnetic reversing valves and exhaust throttle valves (CV3 series), there are electromagnetic reversing valves and one-way throttle valves (CVS1 series), there are electromagnetic reversing valves, exhaust throttle valves and use quick change joints (CVM3, CVM5 series) Column).
The single electronically controlled valve cylinder has no memory effect, cuts off the electrical signal, the reversing valve is reset, and the cylinder is reversed accordingly. Dual electronic control valve cylinder has a memory effect, cut off the electrical signal, the valve position is unchanged, the motorcycle cylinder piston rod position is also unchanged, the pneumatic system is not affected by sudden power failure.
Valve cylinder principle
A valve cylinder is a combined pneumatic actuator composed of a cylinder, a reversing valve and a speed control valve. As shown in Figure 6 below, it eliminates the connection pipe and pipe joint, reduces the energy loss, and has the advantages of compact structure and easy installation. The valve with valve cylinder has various control methods such as electronic control, gas control, mechanical control and manual control. The installation form of the valve is installed in the tail of the cylinder, the upper part and so on. As shown in Figure 4 below, the solenoid reversing valve is installed in the upper part of the cylinder. When there is an electrical signal, the solenoid valve is switched, and the output air pressure can directly control the cylinder action.
