Description

technical field [0001] The invention relates to the field of solenoid valves, in particular to a solenoid valve integrated with a bottle cap. Background technique [0002] The gas cylinder valve refers to the valve installed on the gas cylinder to control the on-off and flow of gas. Most of the existing gas cylinder valves are manual two-way valves, which are used to control the on-off of the gas circuit; Solenoid valves are used to control the flow of gas. For example, in the production measurement of oil wells in oil fields, rotary electromagnetic three-way valves are used for measurement. The solenoid valve is composed of an electromagnetic part and a valve body. The electromagnetic part is composed of a fixed iron core, a moving iron core and a coil. , electromagnetic coil, ejector rod, valve port and armature. When not electrified, the ejector rod of the solenoid valve pushes against the conical valve port under the action of spring force, so that the valve port is clo...

AI Technical Summary

Problems solved by technology

[0003] From the perspective of driving, the existing solenoid valve uses a mechanical spring as a recovery mechanism. To keep the valve open, the coil must be continuously energized so that the ejector rod can always press the spring, so that the valve port is unobstructed. However, the mechanical The spring brings two main defects. First, with the increase of the opening times of the solenoid valve, the mechanical spring will inevitably fail, which is mainly manifested in the change of the spring stiffness. The spring stiffness gradually decreases with the increase of the number of stretches. This will reduce the force of the ejector rod to press the valve port, making the valve port seal unreliable. The shortcomings of the valve are more obvious, and the long-term power supply will cause serious copper loss, which will cause serious heating of the valve;

[0004] Structurally speaking, the driving part of the traditional solenoid valve is separated from the fluid circuit, so the electromagnetic components will take up more space, and at the same time, the driving direction and the fluid flow direction are perpendicular to each other, which will have an adverse effect on the layout of the fluid circuit. Under such circumstances, the use of traditional solenoid valves is greatly limited,

[0005] In terms of space utilization, the structure of the spring and the ejector rod is not conducive to the miniaturization of the solenoid valve. In the case of high space requirements, the traditional solenoid valve is obviously not suitable. In addition, in the hydraulic or pneumatic circuit, the system often requires two Valves (intake control valve and outlet control valve) cooperate with each other to realize their functions, so the pneumatic circuit assembled with traditional solenoid valves will consume a lot of space, making the equipment too bulky, which is not conducive to the portability and miniaturization of the equipment;
