Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 2 In this embodiment, a valve with an antifreeze structure includes a valve body 1. The top and bottom of the valve body 1 are provided with protective components 2 that can effectively protect the valve body 1. The left side of the valve body 1 is provided with a filter component 3 that can effectively filter impurities in the water. The left side of the filter component 3 is fixedly connected to a water inlet pipe 4, and the right side of the valve body 1 is fixedly connected to a drain pipe 5.

[0024] In addition, the valve body 1 includes a valve body 101. The right side of the valve body 101 is fixedly connected to the drain pipe 5. An insulation sleeve 102 is provided on the outside of the valve body 101. The insulation sleeve 102 can protect the valve body 101 and keep it warm, reducing the impact of the external environment on the valve body 101. Multiple antifreeze grooves 103 are provided in the side wall of the valve body 101. A connecting hole 104 connected to the multiple antifreeze grooves 103 is provided in the side wall of the valve body 101. A blocking part 105 extending to the outside of the valve body 101 is provided on the inner rear wall of the valve body 101. By rotating the blocking part 105, the water flow can be controlled and the opening and closing effects can be achieved.

[0025] It is known that the valve body 101 has a liquid inlet hole on the rear side that communicates with the antifreeze tank 103. The inner side of the liquid inlet hole is fixedly connected to a connector extending to the outer side of the valve body 101. The inner side of the connector is hollow, which facilitates the smooth injection of antifreeze into the liquid inlet hole. The inner side of the connector is threaded with a blocking plug. The multiple antifreeze tanks 103 are filled with antifreeze. Antifreeze is injected into the liquid inlet hole from the connector and then injected into the multiple antifreeze tanks 103 through the connecting hole 104.

[0026] It should be further explained that the blocking part 105 includes a rotating rod 1051 rotatably connected to the inner rear wall of the valve body 101 via a bearing. When the turntable 1053 is rotated, the driving force of the turntable 1053 is transmitted to the stop block 1052 through the rotating rod 1051. The stop block 1052 is fixed on the outer surface of the rotating rod 1051 and located inside the valve body 101. By rotating the stop block 1052, the liquid flow rate is controlled and the functions of opening and closing are realized. The rotating rod 1051 penetrates the front side wall of the valve body 101, and the outer surface of the rotating rod 1051... A turntable 1053 is fixed on the outer side of the valve body 101. A sealing groove is opened on the inner rear wall of the valve body 101. Two sealing bearings are fixed on the outer surface of the rotating rod 1051. The two sealing bearings have good sealing performance and can provide good support force for the rotating rod 1051 to ensure stable rotation of the rotating rod 1051. The rotating rod 1051 is rotatably connected to the sealing groove and the top wall of the valve body 101 through the two sealing bearings respectively. The top and bottom of the stop block 1052 are respectively attached to the top wall and bottom wall of the inner cavity of the valve body 101.

[0027] In this embodiment, the antifreeze can be an aqueous solution of ethylene glycol, which has a high specific heat capacity and can effectively delay temperature changes. Then, by cooperating with the insulation jacket 102, it can effectively insulate the valve body 101 and reduce the impact of the external environment on the valve body 101.

[0028] Please refer to it again. Figure 1 and Figure 3In order to improve the service life of the device, each protective component 2 in this embodiment includes two stabilizing parts 201 fixed to the valve body 101. The stabilizing parts 201 are used to provide stable support for the entire protective component 2. Each stabilizing part 201 is provided with a buffer part 202. When the external force is not directly facing the buffer part 202, the external force can be absorbed by the buffer part 202 separating from the stabilizing part 201, thereby reducing the impact of the external force on the valve body 101.

[0029] Furthermore, each stabilizing part 201 includes a stabilizing cylinder 2011 fixed to the outer surface of the valve body 101. A connecting spring 2012 is movably connected inside each stabilizing cylinder 2011. When subjected to external force, the connecting spring 2012 is passively compressed, accumulating elastic potential energy. When the external force disappears, the elastic potential energy is released, thus protecting the valve body 101. Simultaneously, the insulation sleeve 102 also protects the valve body 101. The side of each connecting spring 2012 closest to the valve body 101 is fixed to the valve body 101. Each buffer part 20... Both include two sliding blocks 2021. Each sliding block 2021 is located inside the stabilizing cylinder 2011 and is fixed to the connecting spring 2012. The top of each sliding block 2021 is fixed with a connecting rod 2022 extending out of the stabilizing cylinder 2011. A baffle 2023 is fixed between every two connecting rods 2022. The baffle 2023 is mainly used to protect the top and bottom parts of the valve body 101. Although it cannot provide comprehensive protection for the valve body 101, it has a better protective effect than a valve without a protective structure.

[0030] In addition, the filter assembly 3 includes a housing 301 that is fixedly connected to the left side of the valve body 101. The left side of the housing 301 is fixedly connected to the water inlet pipe 4. A threaded platform 302 is fixedly provided on the inner right wall of the housing 301. A filter element 303 is threadedly connected to the outer surface of the threaded platform 302. The threaded platform 302 is hollow, and the hollow threaded platform 302 can ensure that the liquid flows smoothly into the valve body 1.

[0031] In this embodiment, the top of the outer casing 301 is provided with a sealing door. After opening the sealing door, the filter element 303 can be replaced smoothly. The filter element 303 can filter impurities in the liquid. By reducing impurities in the liquid, condensation nuclei are reduced, further slowing down the freezing rate.

[0032] It is understandable that by using the insulation jacket 102 in conjunction with antifreeze, the insulation effect of the valve can be improved, thereby slowing down the freezing rate. Then, the filter element 303 filters impurities in the liquid, further slowing down the freezing rate of the liquid.

[0033] The working principle of the above embodiments is as follows:

[0034] During use, the liquid first enters the outer casing 301 through the water inlet pipe 4. When the liquid passes through the filter element 303, the filter element 303 can filter the impurities in the liquid to a certain extent. After the impurities are reduced, the condensation nuclei will be reduced, which can effectively reduce the freezing speed of the liquid. With the cooperation of the insulation jacket 102 and antifreeze, the insulation effect of the valve body 101 can be improved, further reducing the freezing speed of the liquid. When an external force is encountered, the external force will act on the baffle 2023, and the baffle 2023 will transmit the force to the connecting spring 2012, causing the connecting spring 2012 to compress. At this time, the connecting spring 2012 will accumulate elastic potential energy. When the external force disappears, the connecting spring 2012 releases the elastic potential energy, causing the baffle 2023 to return to its original position, thus effectively protecting the valve body 1.
