[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0023] like Figs. 1-3 As shown, the present invention proposes a high-reliability solenoid valve, including a valve body 11, a valve seat 12 formed on the upper part of the valve body 11, a valve cover 13 installed on the top of the valve seat 12, and a drive device 2 provided above the valve cover 13.

[0024] The valve body 11 has valve ports 14 at both ends, and a pipe 3 is installed in the valve port 14.

[0025] The bottom corner of the valve body 11 is provided with a support 4, and two adjacent supports 4 are connected by an angle support 5.

[0026] The clamping mechanism comprises a track 61 formed in the support 4, a slide table 62 slidably installed in the track 61, a protruding suspension plate 63 installed on the side wall of the slide table 62, a spring member 64 installed on the suspension plate 63 and facing the pipeline 3, and a clamping ring 65 attached to the pipeline 3 and connected to the other end of the spring member 64.

[0027] It should be noted that the output end of the driving device 2 is connected with a valve rod, the other end of the valve rod is connected with a valve core separating the valve cavity in the valve body 11, the valve rod driven by the output end of the driving device 2 moves up and down, driving the valve core to move up and down in the valve cavity, and the opening and closing of the passage of the valve cavity in the valve body 11 are carried out.

[0028] In this embodiment, the support 4 is improved to an "L-shaped" structure, the track 61 and the slide table 62 are arranged on the longer end of the support 4, and the pipeline 3 is installed at the valve port 14 at both ends of the valve body 11. At this time, the slide table 62 is slid in the track 61, the suspension plate 63 is moved to the position of the middle section outside the pipeline 3, the clamping ring 65 connected to the spring member 64 is compressed in the direction of the suspension plate 63 by the pipeline 3, and the symmetrical clamping rings 65 stably clamp the pipeline 3 under the action of the restoring force of the spring member 64. The pipeline 3 is stably supported on the side edge for connection with the electromagnetic valve, effectively solving the problems of poor installation stability and insufficient reliability of the electromagnetic valve.

[0029] It can be understood that three spring members 64 are arranged, the clamping ring 65 connected to the other end of the three spring members 64 is attached to the pipeline 3, and the spring members 64 are in a compressed state. In this application, the upper, middle and lower parts of the clamping ring 65 are connected with three spring members respectively, the inner wall of the clamping ring 65 directly contacts the pipeline 3, and the pipeline 3 is tightly clamped between the two clamping rings 65 by the restoring force of the spring member.

[0030] Alternatively, the clamping ring 65 is also designed in a segmented manner and cooperates with one spring member 64 respectively, and the spring member 64 deforms at multiple points, thereby improving the clamping stability of the clamping ring 65 through cooperation with the pipeline 3.

[0031] In order to externally support the electromagnetic valve, further, the bottom of the support 4 contacts the ground, and the valve body 11 is lifted and supported at the corner of the valve body 11. Correspondingly, a gap is left between the valve body 11 and the ground, and the valve body 11 is no longer supported by the pipeline 3 and suspended in the air, preventing the electromagnetic valve from being separated from the pipeline 3 after a long period of use.

[0032] In order to facilitate the connection of the pipeline 3 and the valve port 14, further, the end of the pipeline 3 towards the valve port 14 is a convex structure, the convex end of the pipeline 3 penetrates into the inner cavity of the valve port 14, and the convex section of the pipeline 3 is wrapped with a waterproof raw material belt to prevent water seepage at the interface of the pipeline 3 and the valve port 14.
