Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0020] Example 1: Please refer to Figures 1 to 2 A check valve with a heat insulation and antifreeze structure includes a valve body 1, a connection port 2, and a top connection port 3. Connection ports 2 are provided on the left and right sides of the valve body 1, and the top connection port 3 is fixedly provided in the middle of the valve body 1. A heat insulation component 4, a sleeve component 5, and a snap-fit ​​component 6 are provided on the valve body 1. The heat insulation component 4 is provided on the valve body 1, the sleeve component 5 is provided on the heat insulation component 4, and the snap-fit ​​component 6 is provided on both sides of the heat insulation component 4.

[0021] The insulation layer 401 in the insulation component 4 is appropriately connected to the valve body 1, and a wrapping layer 402 is provided on one end of the insulation layer 401.

[0022] In use, align the insulation layer 401 of the insulation component 4 with the valve body 1 and directly slip it onto the valve body 1, so that the insulation layer 401 fits tightly against the valve body 1. At this time, the wrapping layer 402 on one side of the insulation layer 401 is naturally located on one side of the valve body 1, preparing for the subsequent connection with the installation layer 403. This slip-on method is simple to operate, requires no complicated tools or steps, and can quickly complete the initial installation of the insulation layer 401 on the valve body 1, laying the foundation for the construction of the entire insulation structure.

[0023] Example 2: Based on Example 1, please refer to... Figures 2 to 3 An installation layer 403 is provided on the other end of the insulation layer 401 in the insulation component 4. The installation layer 403 is adapted to and fixedly connected to the wrapping layer 402.

[0024] The socket layer pillars 501 in the socket assembly 5 are evenly arranged in the middle of the insulation layer 401, and the socket layer pillars 501 are tightly attached to the outside of the top connection port 3.

[0025] In use, after the insulation layer 401 is fitted onto the valve body 1, the mounting layer 403 on the other side of the insulation layer 401 is aligned with the wrapping layer 402. Since the mounting layer 403 and the wrapping layer 402 are compatible, the connection process is relatively smooth. At the same time, the sleeve layer pillars 501 of the sleeve assembly 5 are evenly arranged in the middle of the insulation layer 401. The sleeve layer pillars 501 are tightly fitted to the outside of the top connection port 3 to ensure that the top connection port 3 is wrapped, which initially enhances the insulation effect of the top and allows the insulation structure to play a good insulation role in the middle of the valve body 1.

[0026] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The end of the sleeve layer column 501 in the sleeve assembly 5 is provided with a sleeve protrusion 502. The sleeve protrusion 502 is adapted to fit tightly with the sleeve elastic ring 503. The bottom end of the sleeve elastic ring 503 is provided with a snap-fit ​​interface 504, which snaps onto the insulation layer 401.

[0027] The snap-fit ​​sleeves 601 in the snap-fit ​​assembly 6 are evenly and fixedly disposed on the outside of the mounting layer 403. The snap-fit ​​sleeves 601 are fitted and fixedly engaged with snap-fit ​​protrusions 602, which are evenly disposed on the inside of the wrapping layer 402.

[0028] In use, the elastic ring 503 of the sleeve assembly 5 is placed on the sleeve protrusion 502 at the end of the sleeve layer column 501. The elasticity of the elastic ring 503 allows it to fit tightly with the sleeve protrusion 502. Then, the snap-fit ​​interface 504 at the bottom end of the elastic ring 503 is snapped onto the insulation layer 401 to further fix the sleeve assembly 5 and enhance the top insulation effect. At the same time, the snap-fit ​​protrusions 602 of the snap-fit ​​assembly 6 are evenly distributed on the inner side of the wrapping layer 402. The snap-fit ​​protrusions 602 are aligned with the snap-fit ​​sleeves 601 on the outer side of the mounting layer 403 and pressed to make the snap-fit ​​protrusions 602 and snap-fit ​​sleeves 601 fit together and fix them. This completes the quick fixation of the wrapping layer 402 and the mounting layer 403 without tools, greatly shortening the installation time and forming a complete and sealed insulation layer that effectively blocks the external low temperature and prevents the medium in the valve body from freezing.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
