Abstract

The invention provides an electromagnetic valve. The electromagnetic valve comprises a valve body component, a piston component and an auxiliary valve. The valve body component is provided with a containing cavity, an inlet and an outlet, wherein the inlet and the outlet communicate with the containing cavity. The piston component is movably arranged in the containing cavity and provided with a balance channel, the two ends of the balance channel are provided with a first opening and a second opening correspondingly, the first opening is located in the side, deviating from the outlet, of the piston component, and the second opening communicates with the inlet. The piston component has a closing position and an opening position, and under the condition that the piston component is at the closing position, the piston component blocks the outlet; and under the condition that the piston component is at the opening position, the piston component avoids the outlet and the inlet. The auxiliary valve is movably arranged in the balance channel, a preset gap is formed between the auxiliary valve and the inner wall of the balance channel, and the auxiliary valve has a first state for blocking the first opening and a second state for avoiding the first opening. By adopting the scheme, the problem that the electromagnetic valve is not easy to open in a high-pressure environment can be solved.

Description

technical field [0001] The present invention relates to the technical field of solenoid valves, in particular to a solenoid valve. Background technique [0002] The piston part of the solenoid valve is used to block the outlet of the solenoid valve, and the piston part is provided with a penetrating balance channel. For the case of small pressure difference, the on-off valve is relatively stable. The flow capacity of the balance channel of the solenoid valve and the pilot valve port is related to the pressure. The balance channel is on the high pressure side, and the pilot valve port is on the low pressure side. When the pressure difference is high, the valve is opened. It is a gaseous environment, the gas is compressed, and the density increases. Under the same pressure difference, the flow capacity of the high-pressure environment is greater than that of the low-pressure environment, so the flow capacity is relatively high. In this way, the flow capacity around the piston ...
