Detailed Implementation

[0023] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0024] Please see Figures 1-5 This application provides a combined solenoid valve, including a combined solenoid valve body 10 and a thermal insulation and protection component 20.

[0025] The combined solenoid valve body 10 is used to control the opening and closing of the valve, enabling remote control and featuring precision, speed, and controllability. The thermal insulation and protection component 20 protects and insulates the combined solenoid valve body 10, thereby improving its service life and safety performance.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The thermal insulation and protection component 20 includes a first protective shell 210 and a second protective shell 220, which are detachably connected to each other. Specifically, the second protective shell 220 is provided with a glass window 260, the side wall of the first protective shell 210 is provided with an insert plate 270, and the side wall of the second protective shell 220 is provided with a slot 221 that mates with the insert plate 270. The first and second protective shells are generally made of materials such as thermal insulation cotton or foam, and the materials should be selected with excellent waterproof, impact-resistant, and oxidation-resistant properties. These materials are then covered with an additional protective plate. The combined solenoid valve body 10 is located inside the first and second protective shells 210 and 220. The side walls of the first and second protective shells 210 and 220 are provided with arc-shaped clearance grooves 280 at both ends of the combined solenoid valve body 10. When multiple solenoid valves are assembled and installed on a pipeline, the first protective shell 210 and the second protective shell 220 are opened, allowing the two arc-shaped clearance grooves 280 on both sides to engage with the pipelines at both ends of the combined solenoid valve body 10. Then, the first protective shell 210 and the second protective shell 220 are connected from above. The first and second protective shells 210 and 220 serve two purposes: firstly, they protect the combined solenoid valve body 10 from accidental contact; secondly, they provide insulation, especially in low-temperature environments, maintaining the temperature around the combined solenoid valve body 10 and improving the solenoid valve's service life and safety performance. Furthermore, installation can be customized according to actual conditions, allowing for installation in low-temperature environments while eliminating the need for installation in warmer environments. This convenient disassembly and installation method offers user convenience.

[0027] In this embodiment, the first protective shell 210 and the second protective shell 220 are provided with elastic clamping members 290 at the arc-shaped relief groove 280. Each elastic clamping member 290 includes an arc-shaped clamping plate 291 and an elastic connecting part 292. The elastic connecting part 292 is connected to the inner wall of the arc-shaped relief groove 280, and the arc-shaped clamping plate 291 is connected to the elastic connecting part 292. The elastic connecting part 292 includes a clamping spring 2921 and a mounting plate 2922. The mounting plate 2922 is connected to the inner wall of the arc-shaped relief groove 280, the clamping spring 2921 is connected to the mounting plate 2922, and the arc-shaped clamping plate 291 is connected to the clamping spring 2921. Each arc-shaped relief groove 280 has an arc-shaped groove 211 on its inner wall, and the mounting plate 2922 is connected to the inner wall of the arc-shaped groove 211, so that the arc-shaped clamping plate 291 can retract into the arc-shaped groove 211. An elastic protective pad 293 is attached to the arc-shaped clamping plate 291. When the two sets of arc-shaped clearance grooves 280 are respectively engaged with the pipes at both ends of the combined solenoid valve body 10, they will first contact the two sets of arc-shaped clamping plates 291. Under the action of the clamping spring 2921, the two sets of arc-shaped clamping plates 291 tightly clamp the pipes. The cooperation between the clamping spring 2921 and the arc-shaped clamping plates 291 allows for the clamping of pipes of various diameters, thereby improving the versatility of the thermal insulation and protection component 20 and making it suitable for most installation environments.

[0028] In this embodiment, the bottoms of the first protective shell 210 and the second protective shell 220 are hinged, and a connecting bolt 250 is provided on the top of both the first protective shell 210 and the second protective shell 220. A first ear plate 230 and a second ear plate 240 are respectively fixedly connected to the top of the first protective shell 210 and the second protective shell 220, and the connecting bolt 250 is disposed on the first ear plate 230 and the second ear plate 240. The connecting bolt 250 enables a detachable connection between the first protective shell 210 and the second protective shell 220, facilitating the disassembly of the thermal insulation protection component 20 for installation as needed.

[0029] The working principle of this combined solenoid valve is as follows:

[0030] After multiple solenoid valves are assembled and installed on the pipeline, the first protective shell 210 and the second protective shell 220 are opened, allowing the two arc-shaped clearance grooves 280 on both sides to engage with the pipelines at both ends of the combined solenoid valve body 10. Then, the first protective shell 210 and the second protective shell 220 are connected from above. The first and second protective shells 210 and 220 serve two purposes: firstly, they protect the combined solenoid valve body 10 from accidental contact; secondly, they provide insulation, especially in low-temperature environments, maintaining the temperature around the combined solenoid valve body 10 and improving the solenoid valve's service life and safety performance. Furthermore, installation can be customized according to actual conditions, allowing for installation in low-temperature environments while eliminating the need for installation in warmer environments. This convenient disassembly and installation makes it easy for users to choose the appropriate option.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
