Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a solenoid valve that is easy to connect. Background Art

[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulic or pneumatic drives. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Usually, solenoid valves need to be installed between two pipes using several mounting bolts.

[0003] In order to facilitate the installation of the solenoid valve between two pipes, the prior art has made many improvements to the solenoid valve. For example, the patent with patent publication number CN218598941U discloses a solenoid valve that is easy to connect, including a bottom channel, first connecting pipes are fixedly connected on both sides of the bottom channel, second connecting pipes are installed inside the first connecting pipe, limiting grooves are provided in the middle of the upper and lower ends of the first connecting pipe, fixed sleeves are fixedly connected to the outside of the limiting grooves, movable rods are movably connected to the inside of the fixed sleeves, clamps are fixedly connected to the inside of the movable rods, strong springs are installed on the inner side of the outer ends of the movable rods, the outer sides of the strong springs are fixedly connected to the fixed sleeves, the inner sides of the strong springs are fixedly connected to the clamps, and clamping grooves are provided in the middle of the upper and lower ends of the two second connecting pipes, which can realize the quick connection of the two connecting pipes and the solenoid valve, while ensuring that the connection between the connecting pipes and the solenoid valve is firm and sealed, thereby improving the convenience and sealing of the solenoid valve.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative document, the movable rod is pulled, and the second connecting pipe at the end of the connecting pipe is inserted into the first connecting pipe, and the first connecting pipe and the second connecting pipe are installed by clamping the clamp in the clamping groove. In actual operation, when the solenoid valve body fails, the entire solenoid valve body needs to be dismantled and replaced or maintained. Since the first connecting pipes at both ends of the solenoid valve body are limited by the second connecting pipe, it is necessary to remove the connecting pipe at at least one end before the solenoid valve body can be removed and taken out, and the end of the connecting pipe away from the solenoid valve body needs to be removed, which makes it inconvenient to disassemble and connect the solenoid valve body during maintenance. Therefore, there is an urgent need in this field to improve the solenoid valve that is easy to connect, so as to solve the defects of the prior art. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a solenoid valve that is easy to connect.
