Abstract

The invention provides a programmable-control four-channel valve device and a using method thereof, and relates to the field of automatic control valves for controlling fluid valves. By adoption of the programmable-control four-channel valve device and the using method thereof, the problems that internal leakage and external leakage happen to an existing pneumatic valve and an existing electric valve, the utilization rate of an execution element is low, and an electromagnetic valve can only achieve control over opening and closing and cannot be used for adjusting the opening degree are solved. The programmable-control four-channel valve device is composed of a stepping motor, an elastic coupling, a motor support, a mounting base, a base, a cam mechanism, a first driven mechanism, a second driven mechanism, two hose fixing frames, eight hose connectors, a first channel hose, a second channel hose, a third channel hose, a fourth channel hose and a PLC. The using method of the programmable-control four-channel valve device comprises the first step of control over the on-off state of a first channel and a second channel, the second step of control over the on-off state of a third channel and a fourth channel, the third step of control over the opening degree of the first channel or the second channel, and the fourth step of control over the opening degree of the fourth channel or the third channel.

Description

Technical field [0001] The invention relates to the field of automatic control valves controlled by fluid valves. Background technique [0002] At present, the control valves commonly used in production and life are mainly pneumatic valves, electric valves and solenoid valves. Pneumatic valves use compressed air to drive the actuator to drive the spool to realize the on-off control and opening adjustment of the valve. It has high reliability, but it must rely on a complex air source system and control system. The electric valve uses electric energy as power to switch on the electric actuator to drive the valve core to realize the on-off control and opening adjustment of the valve. It has high control accuracy, but the torque control is not easy and may even break the stem head, and it is easy to produce internal leakage. Pneumatic valves and electric valves control the rotation or movement of the spool, which must solve the problem of external leakage of the valve stem dynamic ...
