[0025] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices consistent with some aspects of the present application as detailed in the appended claims.

[0026] refer to Figure 1 The present specific embodiment provides an opening and closing self-release antifreeze gate, including a pipe body, on which a water outlet 6, a drain port 5 and a water inlet are arranged, the water outlet 6, the drain port 5 and the water inlet are all connected with a passage 14 inside the pipe body, the water inlet can be connected with a tap water pipe or other fluid pipeline, the water outlet 6 is used for water supply or fluid outflow for people's use; the drain port 5 can be connected with a sewer or a seepage pit, so as to discharge the water in the pipe body into the sewer or the seepage pit, so that water supply, water discharge and water discharge can be realized.

[0027] Among them, the opening and closing self-release anti-freeze gate also includes a drain valve plug 13, a water supply plug 11 and an adjusting part. The drain valve plug 13 is used to block the drain port 5, the water supply plug 11 is used to block the water inlet, and the adjusting part is used to control the drain valve plug 13 and the water supply plug 11 to respectively block the drain port 5 and the water inlet.

[0028] When the adjusting member rotates along the first direction, the drain valve plug 13 moves away from the drain port 5, so that the drain port 5 is opened and connected with the passage 14, and the water or fluid in the passage 14 is discharged through the drain port 5. At this time, the upper water plug 11 closes the water inlet, so that water or fluid can no longer enter the passage 14 through the water inlet, thereby achieving waterlessness in the passage 14. In this way, in a low-temperature environment, there is no water in the pipe body and it will not freeze, so it is not easy to be frozen and will not cause the pipe body to be blocked.

[0029] When the adjusting member rotates in the second direction, the drain valve plug 13 closes the drain port 5, so that the water or fluid in the passage 14 cannot flow out from the drain port 5, and the water supply plug 11 opens the water inlet, so that the water or fluid can continue to enter the passage 14 from the water inlet for people to use.

[0030] With such arrangement, water or fluid in the passage 14 of the pipe body can be discharged through the drain port 5, and the pipe body will not be frozen in winter. Moreover, since there is no water in the pipe body, it will not be blocked and is not easily cracked by freezing, thus solving the problem that the water retained in the existing water pipe is easy to freeze in winter and block the pipe or even crack the pipe.

[0031] In this embodiment, a through groove 12 is further provided in the pipe body, and the through groove 12 can be connected with the drain port 5 and the passage 14, so that the water or fluid in the passage 14 can flow into the drain port 5 through the through groove 12. The drain valve plug 13 matches the through groove 12, and the drain valve plug 13 can be embedded in the through groove 12 and block the drain port 5.

[0032] When the adjusting member rotates in the first direction, the drain valve plug 13 moves away from the through groove 12, and the through groove 12 is connected with the passage 14 and the drain port 5. At this time, the water or fluid in the passage 14 flows into the through groove 12 and flows out from the drain port 5, thereby achieving drainage. When the adjusting member rotates in the second direction, the drain valve plug 13 is embedded in the through groove 12, and the drain valve plug 13 blocks the drain port 5, so that the water or fluid in the passage 14 cannot enter the through groove 12, and thus cannot flow out from the drain port 5.

[0033] Furthermore, the water inlet includes a lower water inlet 4 and a first through hole 10, and the first through hole 10 can be connected with the lower water inlet 4 and the passage 14, so that the water or fluid entering through the lower water inlet 4 can flow into the passage 14 through the first through hole 10, and then flow out from the water outlet 6 for people to use. Among them, the upper water plug 11 is located between the lower water inlet 4 and the first through hole 10, and the upper water plug 11 can block the first through hole 10, so that water or fluid cannot enter the passage 14. In this way, when used in winter, water will not be stored in the passage 14 of the pipe body and ice will not block the pipe body.

[0034] When the adjusting member rotates in the first direction, the upper water plugging member 11 can move upward, and the top end of the upper water plugging member 11 is in close contact with the first through hole 10, thereby closing the first through hole 10 and preventing water or fluid from entering the passage 14 through the first through hole 10.

[0035] When the adjusting member rotates in the second direction, the water supply plug 11 can move downward, so that the water supply plug 11 is away from the first through hole 10, thereby opening the first through hole 10 and allowing water or fluid to enter the passage 14 to achieve normal water supply.

[0036] Specifically, the first direction can be clockwise, and the second direction can be counterclockwise. When the adjusting part rotates clockwise, it can drive the drain valve plug 13 and the water supply plug 11 to rotate and move upward. When the adjusting part rotates counterclockwise, it can drive the drain valve plug 13 and the water supply plug 11 to rotate and move downward.

[0037] In this embodiment, the adjusting member includes a screw rod 9 and a switch handle 8. The switch handle 8 is used to control the screw rod 9. By rotating the switch handle 8, the screw rod 9 can be controlled to rotate, thereby driving the drain valve plug 13 and the water supply plug 11 to rotate and move.

[0038] The screw 9 extends into the pipe body and is fixedly connected with the drain valve plug 13 and the water supply plug 11. Specifically, the drain valve plug 13 and the water supply plug 11 are both sleeved on the screw 9. The switch handle 8 is located above the pipe body and is fixedly connected with the top of the screw 9. The user rotates the switch handle 8 to drive the screw 9 to rotate, thereby realizing water supply and draining.

[0039] In order to prevent the screw 9 from shifting, a screw positioning plate is provided in the pipe body, and a first threaded hole is provided on the screw positioning plate. The first threaded hole matches the screw 9. The screw 9 passes through the first threaded hole and can move up and down along the axial direction of the first threaded hole, thereby driving the drain valve plug 13 and the water supply plug 11 to move up and down.

[0040] Here, the screw positioning disk and the pipe body can be an integrated structure to reduce the connection structure and improve the stability of the connection between the screw positioning disk and the pipe body.

[0041] Furthermore, in order to avoid obstruction of water supply, a second through hole for water or fluid to pass through is provided on the screw positioning disk, and the second through hole is connected to the passage 14 .

[0042] In some embodiments, the pipe body includes an upper valve body 2, a lower valve body 1 and a water guide pipe 3 for connecting the upper valve body 2 and the lower valve body 1. The upper valve body 2 is arranged above the ground, and the water outlet 6 is located on the upper valve body 2 for easy use by people. The lower valve body 1 is arranged below the ground, and the drain port 5 and the water inlet are both arranged on the lower valve body 1, so that water inlet and drain are convenient, and the probability of freezing can be reduced, thereby increasing the service life of the opening and closing self-release antifreeze gate.

[0043] Among them, the screw positioning plate includes a first screw positioning plate 17 and a second screw positioning plate 18. The first screw positioning plate 17 is arranged in the lower valve body 1, and the first screw positioning plate 17 is arranged between the lower water inlet 4 and the upper water plug 11 to limit the bottom end of the screw 9; the second screw positioning plate 18 is arranged in the upper valve body 2, and the second screw positioning plate 18 is arranged close to the bottom end of the upper valve body 2 to limit the middle and upper part of the screw 9, thereby further avoiding the deviation of the screw 9 and ensuring that the drain valve plug 13 and the upper water plug 11 can block the drain port 5 and the first through hole 10.

[0044] It should be noted that the first screw positioning plate 17 and the second screw positioning plate 18 are both provided with a first threaded hole and a second through hole to match the screw 9 and will not hinder the water supply.

[0045] In other embodiments, a check valve 15 is provided at the top of the pipe body, that is, a check valve 15 is provided at the top of the upper valve body 2, and the check valve 15 is used to fix the adjusting member to position the adjusting member.

[0046] The check valve 15 is fixedly connected to the pipe body, and a second threaded hole is provided on the check valve 15 , and the second threaded hole matches the screw rod 9 , so that the screw rod 9 can pass through the second threaded hole and extend into the pipe body.

[0047] A slot is provided at the top of the upper valve body 2 , and the bottom end of the check valve 15 is embedded in the slot and closely matched with the slot, thus improving the stability of the connection between the check valve 15 and the upper valve body 2 .

[0048] In order to avoid water leakage at the top of the upper valve body 2, a water blocking strip 16 is provided between the stop valve 15 and the pipe body (i.e., between the stop valve 15 and the upper valve body 2). The water blocking strip 16 is sleeved outside the screw 9, and the water blocking strip 16 is tightly matched with the screw 9. Here, the water blocking strip 16 can be provided in the card groove to seal the gap between the bottom end of the card groove and the screw 9 to prevent water or fluid in the passage 14 from flowing out through the gap.

[0049] It should be noted that the water blocking strip 16 may be a packing.

[0050] In this embodiment, the cross-sectional shape of the through groove 12 and the drain valve plug 13 can be trapezoidal, and the diameters of the through groove 12 and the drain valve plug 13 gradually decrease from top to bottom. In this way, when the screw 9 rotates counterclockwise to drive the drain valve plug 13 into the through groove 12, it is convenient for the drain valve plug 13 to enter the through groove 12, thereby facilitating the sealing of the drain port 5.

[0051] The cross-sectional shape of the upper water plugging member 11 may also be trapezoidal, and the maximum outer diameter of the upper water plugging member 11 is smaller than the diameter of the lower water inlet 4, that is, the maximum outer diameter of the upper water plugging member 11 is smaller than the inner diameter of the lower valve body 1, so that water or fluid can pass through the gap between the upper water plugging member 11 and the inner wall of the lower valve body 1. The minimum outer diameter of the upper water plugging member 11 is larger than the diameter of the first through hole 10, so that the upper water plugging member 11 can block the first through hole 10, so that water or fluid cannot pass through the first through hole 10.

[0052] Here, the diameter of the upper water plugging member 11 gradually increases from top to bottom, that is, the diameter of the top end of the upper water plugging member 11 is larger than the diameter of the first through hole 10 , so that the first through hole 10 can be blocked.

[0053] It should be noted that the drain valve plug 13 and the water supply plug 11 can be made of rubber or silicone, or other materials, which are not specifically limited here.

[0054] Preferably, the drain port 5 is connected to the through groove 12 through the drain pipe 7, and the drain pipe 7 is arranged obliquely, and the drain port 5 is lower than the through groove 12 to facilitate the outflow of water or fluid. Here, the drain pipe 7 and the lower valve body 1 are in an integrated structure.

[0055] The present specific embodiment provides an open and close self-release antifreeze gate. When in use, the lower valve body 1 is buried below the frozen layer and a seepage pit or underground water storage tank or sewer is prepared. The drain port 5 is connected to the seepage pit or underground water storage tank or sewer, so that the upper valve body 2 is located above the ground. The switch handle 8 is rotated clockwise, and the switch handle 8 drives the screw rod 9 to rotate clockwise and drives the drain valve plug 13 to move upward, so that the drain port 5 is opened and water is discharged. At this time, the upper water plug 11 moves upward to block the first through hole 10, that is, the upper water plug 11 is opened. The plugging piece 11 cuts off the water source, and water cannot be supplied any further. The flow in the pipe body is cut off and there is no water in the frozen layer pipe, so there is no water in the pipe and no ice will form and block it. The switch handle 8 is rotated counterclockwise, and the switch handle 8 drives the screw 9 to rotate counterclockwise, and drives the drain valve plugging piece 13 to move downward into the through groove 12 to block the drain port 5, and water cannot be discharged any further. At this time, the water supply plugging piece 11 moves downward away from the first through hole 10, so that the first through hole 10 is connected with the lower water inlet 4 and the passage 14, so that water or fluid can flow freely in the pipe body along the pipe direction, and water supply is achieved.

[0056] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
