Description

An electrical control valve with a quick shut-off mechanism

technical field

The utility model relates to the field of valves, in particular to an electric control valve with a quick cut-off mechanism.

Background technique

The valve is a pipeline part used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. The valve is a control component in the fluid conveying system. It has the functions of cutoff, regulation, diversion, prevention of backflow, voltage stabilization, shunt or overflow pressure relief. In some fields, in order to prevent fluid backflow, it is necessary to quickly shut off the valve. Some valves are usually cut off by a motor, but when the pressure in some pipelines is too large, the motor cut-off method cannot provide enough thrust, and sometimes the closure is not tight enough to cause leakage.

Compared with the prior art, the beneficial effect of the utility model is: when the valve needs to be cut off, the electric push rod starts to push the moving plate to move, the moving plate pushes the oil in the hydraulic bottle to flow, and the oil flows into the control valve through the pipeline. In the control chamber of the box, squeeze the slider, push the slider down, the slider is connected with the piston through the valve stem, and the slider drives the piston to block the connection between the water inlet and the water outlet. When the valve needs to be opened, The electric push rod retracts, the electromagnetic sucker is energized to attract the iron block, and the spring between the iron block and the control box pushes the iron block, so that the electromagnetic sucker smoothly attracts the iron block, and the iron block drives the slider through the connecting rod. When the slider moves up, the oil is squeezed back into the hydraulic bottle, and the slider drives the piston to move, opening the channel between the water inlet and the water outlet.
