Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic valves, in particular to a connecting structure of an electromagnetic valve pipe. 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 accuracy and flexibility of the control can be guaranteed.

[0003] A pipe connection structure and a solenoid valve including the structure are retrieved with the announcement number CN217463653U, which specifically discloses: the patent forms welds between the outer periphery of the main pipe and the saddle-shaped connection part, and between the boss and the main pipe connection part by fitting the saddle-shaped connection part with the main pipe, and the length of the weld can be fully guaranteed. Since the saddle-shaped connection part of the introduction pipe and the main pipe are in single-sided contact, the gap between the main pipe and the saddle-shaped connection part of the introduction pipe can be fully guaranteed, and the density of the weld formed can be fully guaranteed. The saddle-shaped connection part used in the above-mentioned comparative documents is mostly formed by stamping from the pipe. Although it has the effect of convenient processing, the connection process is relatively cumbersome and unusable because the pipe is connected by welding, which greatly reduces the scope of application of the solenoid valve.
