Description

Technical Field

[0001] The utility model relates to the technical field of battery valves, in particular to a two-way solenoid valve. Background Art

[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic components for controlling fluid automation and belong to actuators, not limited to hydraulic and pneumatic. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed. The two-way solenoid valve is a type of solenoid valve.

[0003] At present, the existing solenoid valves are directly installed on the pipeline. When the solenoid valve is started during use, the liquid transported in the pipeline will cause a certain impact on the solenoid valve, thereby causing the solenoid valve to produce certain vibration and noise. The valve core, electromagnet and valve body in the two-way solenoid valve are rigidly connected. When the liquid in the pipeline of the solenoid valve is started and causes an impact on the solenoid valve, the valve core and the electromagnet will be separated from the valve body over time and will also cause certain damage to it, thereby reducing the service life of the two-way solenoid valve.

[0023] As a technical optimization solution of the utility model, the installation assembly includes a mounting tube 12, and one end of the mounting tube 12 is fixedly connected to one end of the buffer member 11, and the other end side surface of the mounting tube 12 is provided with a groove 1201, and the inner surface of the mounting tube 12 is provided with a threaded connection part 1203.

[0024] As a technical optimization solution of the utility model, a mounting sealing ring 1202 is provided on one side of the threaded connection part 1203, and the mounting sealing ring 1202 is fixedly connected to the inner wall of the mounting tube 12. The inner diameter of the mounting sealing ring 1202 is larger than the inner diameter of the mounting tube 12. When the solenoid valve is installed, the mounting end of the solenoid valve will squeeze the mounting sealing ring 1202, thereby improving the connection sealing between the buffer part 11 and the solenoid valve.

Then, when the solenoid valve is started, the liquid inside the pipeline will impact the buffer plate 15 inside the buffer 11, and under the action of the spring 1501, the liquid flowing in the pipeline will be initially buffered. Then, the liquid will enter the interior of the sleeve 14 through the connecting flange 13 on the upper surface of the buffer 11, and at this time, it will push the piston 1404 inside the sleeve 14 to move upward, so that the impact force of the liquid in the pipeline can be further unloaded, and then the liquid in the pipeline will flow to the interior of the valve body 1, thereby reducing the impact force on the solenoid valve and reducing the damage to the solenoid valve. After closing the solenoid valve, the liquid in the pipeline will stop, and at this time, the piston 1404 inside the sleeve 14 will be pushed down by the small return spring 1403 to return to its original position, which is convenient for the next use.
