Description

Integrated switching device

Technical Field

The invention relates to the field of switching devices, in particular to an integrated switching device.

Background

Solenoid valves (Electromagnetic valve) are solenoid-operated industrial equipment, are automated basic elements for controlling fluids, and are actuators, not limited to hydraulic and pneumatic. For use in industrial control systems to adjust the direction, flow, velocity and other parameters of the medium. The solenoid valve can be matched with different circuits to realize expected control, and the control precision and flexibility can be ensured. There are a wide variety of solenoid valves, different solenoid valves functioning at different locations in the control system,

solenoid valves are in principle divided into three main categories: a direct-acting solenoid valve, a stepwise direct-acting solenoid valve and a pilot-operated solenoid valve. Principle of direct-acting solenoid valve: when the electromagnetic valve is electrified, the electromagnetic coil generates electromagnetic force to lift the closing piece from the valve seat, and the valve is opened; when the power is off, the electromagnetic force disappears, the spring presses the closing member against the valve seat, and the valve is closed. Principle of the step-by-step direct-acting electromagnetic valve: the electromagnetic force directly lifts the pilot small valve and the main valve closing member upwards in sequence after the power is applied when the pressure difference between the inlet and the outlet is not generated, and the valve is opened. When the inlet and the outlet reach the starting pressure difference, after the electromagnetic force leads the small valve, the pressure of the lower cavity of the main valve rises, and the pressure of the upper cavity falls, so that the main valve is pushed upwards by utilizing the pressure difference; when the power is off, the pilot valve pushes the closing member to move downwards by utilizing spring force or medium pressure, so that the valve is closed. The characteristics are as follows: can operate even at zero pressure difference, vacuum or high pressure, but has high power and needs to be horizontally installed. Principle of pilot-operated solenoid valve: when the power is on, the electromagnetic force opens the pilot hole, the pressure of the upper chamber drops rapidly, a pressure difference with high upper and lower parts is formed around the closing member, the fluid pressure pushes the closing member to move upwards, and the valve is opened; when the power is off, the spring force closes the pilot hole, the inlet pressure rapidly forms a pressure difference of lower part and higher part around the valve closing member through the side threaded hole, and the fluid pressure pushes the closing member to move downwards to close the valve. The characteristics are as follows: the upper limit of the fluid pressure range is high, and the fluid pressure range can be installed (customized) at will but must meet the fluid pressure difference condition.

At present, the electromagnetic valve box which can be matched with the induction tap in the market is usually directly fixed on a wall, so that the electromagnetic valve box is inconvenient to detach, the battery box of the existing electromagnetic valve cannot be detached, the existing battery box is singly in an external plugging mode, the electromagnetic valve box and the whole electromagnetic valve box are not integrated completely, and in addition, the module design which can be detached conveniently is not realized.
