[0036] The use method of the utility model is as follows:
[0037] When the interception and reverse stop function is not set, the utility model can be used as a simple anti-freezing device, and the preset drainage temperature can be set according to the actual requirement, when the temperature bag senses that the water flow temperature reaches the preset drainage temperature, the upper end of the drain hole is opened, and drainage is carried out.
[0038] Before using the anti-freezing device, the water inlet connector 2 and the water outlet connector 3 can be connected with the pipeline in the pipeline system, at this time, the anti-freezing device is used as an anti-freezing valve, if the water inlet connector is connected with the pipeline, the water outlet connector is installed with a faucet mouth, at this time, the anti-freezing device can be used as an anti-freezing faucet, when the anti-freezing device is installed, the water flow in the pipeline flows into the valve body 1 through the water inlet connector 2 and finally flows out from the water outlet connector 3 for use, when the water flow flows to the water outlet connector 3, part of the water flow flows downward through the gap between the inner wall of the water passage hole 21 and the outer wall of the water guide body 23, and then flows into the shell cover 16 through the water inlet 27, the water inlet groove 26 and the water guide hole 25 in turn, and the water flow in the shell cover 16 directly flows downward into the shell 5 and flows to the drain hole 8, at this time, the temperature bag 14 can sense the temperature at any time, so that the temperature sensing medium 50 in the temperature sensing hole 15 is affected by the temperature change to expand or shrink, which is the temperature sensing principle of the existing temperature bag, when the temperature does not drop to the preset drainage temperature, the lower end of the jacking rod 12 always presses the lower end surface of the adjusting part 9 on the upper end surface of the adjusting screw 7, and the upper end hole of the drain hole 8 is blocked and sealed, when the temperature drops to the preset drainage temperature, the temperature sensing medium 50 in the temperature sensing hole 15 shrinks due to cold, at this time, the adjusting spring 11 pushes the pressure part 10 upward by the elastic force of itself, so that the adjusting part 9 and the jacking rod 12 are synchronously moved upward, when the adjusting part 9 moves upward, the upper end hole of the drain hole 8 is no longer blocked and sealed, and the water flow can be discharged to the outside through the drain hole 8, realizing the effect of automatic drainage.
[0039] When the natural temperature rises, the temperature sensing medium 50 in the temperature sensing hole expands due to heat, and then pushes out the jacking rod 12 downward, at this time, the jacking rod 12 moves downward and pushes the adjusting part 9 downward, and the lower end surface of the adjusting part 9 blocks and seals the upper end hole of the drain hole 8 again, and the water flow is not discharged.
[0040] In conclusion, the utility model discloses can realize the effect of automatic drainage through the opening of the drainage hole 8 on the adjusting screw 7 by the adjusting part 9, and in the case that the temperature bag 14 is fixed, only need to change the height of the adjusting screw 7, thereby changing the height of the upper hole of the drainage hole 8, can adjust the preset drainage temperature, when the adjusting screw 7 is lower, the preset drainage temperature is higher, therefore, the temperature drainage mode can not only realize automatic drainage and the effect of starting anti-freezing, but also has the effect of adjusting the preset drainage temperature.
[0041] In actual use, the height of the adjusting screw 7 can also be adjusted by the adjusting shell 53, in order that the user can quickly and accurately adjust the preset drainage temperature, a plurality of scale values 62 are arranged on the lower outer wall of the shell body 5 in a circumferential uniform distribution, and a specified arrow 63 matched with the scale value 62 is arranged on the upper outer wall of the adjusting shell 53, the scale value aimed at by the specified arrow 63 is how many degrees, and at this moment, the preset drainage temperature is how many degrees, which is simple and clear, when the height of the adjusting screw 7 needs to be changed by the adjusting shell 53, one hand holds the shell body 5, and the other hand holds the adjusting shell 53, at this moment, the shell body 5 is fixed, and then the adjusting shell 53 is pulled down, with the adjusting shell 53 moving down, the locking tooth 52 is separated from the locking tooth groove 56, and because the height of the adjusting tooth 57 is high, when the locking tooth 52 is separated from the locking tooth groove 56, the adjusting tooth 57 is still clamped in the adjusting tooth groove 58, with the rotation of the adjusting shell 53, the adjusting screw 7 rotates synchronously, and the adjusting screw 7 moves up and down along the thread track of the inner wall of the adjusting screw hole 6, so that the height of the adjusting screw 7 is adjusted.
[0042] When the height adjustment of the adjusting screw 7 is completed, the adjusting shell 53 is loosened, and the adjusting shell 53 is reset under the elastic force of the clamping spring 61, when the adjusting shell 53 is reset, the locking tooth 52 is clamped into the locking tooth groove 56 again, at this moment, the two are locked, so that the fixing between the shell body 5 and the adjusting shell 53 is realized, and the adjusting shell 53 cannot rotate relative to the shell body 5 at this moment, avoiding the rotation of the adjusting shell 53 caused by accidental touch, so that the preset drainage temperature is abnormally changed.
[0043] The adjusting shell 53 is screwed with a protective cover 64 sleeved outside the drain nozzle 59, the protective cover 64 is provided with a movable hole 65 matched with the drain nozzle 59 in the center, and the existence of the protective cover 64 can effectively protect the clamping spring 61.
[0044] The elastic force of the auxiliary spring 19 and the elastic force of the adjusting spring 11 can be balanced, so as to limit the temperature bag 14 to a certain height in the shell body 5, if the height of the temperature bag 14 needs to be adjusted, only the shell cover 16 is rotated, the compression state of the auxiliary spring 19 can be changed by the upward movement or the downward movement of the shell cover 16, so that the initial elastic force of the auxiliary spring 19 is changed, and finally the position of the temperature bag 14 is effectively adjusted.
[0045] The lower end of the adjusting screw 7 penetrates downwardly out of the adjusting screw hole 6, and the outer wall of the lower end of the adjusting screw 7 is provided with a rotating part 30.

[0046] The lower end surface of the adjusting part 9 is provided with a sealing groove 48 in the center, and the sealing groove 48 is provided with a sealing gasket 49 matched therewith. The sealing gasket 49 blocks and seals the upper end hole of the drainage hole 8. The existence of the sealing gasket 49 can effectively increase the sealing performance when the lower end of the adjusting part 9 blocks and seals the upper end hole of the drainage hole 8.
[0047] Please refer to Figures 6 to 8 The water inlet connector 2 can be used to connect a water inlet pipeline, and the water outlet connector 3 can be used to connect a water outlet pipeline or a faucet nozzle and the like. When the opening and closing hole 33 of the valve ball 32 is coaxial with the water inlet connector 2, the water flow in the water inlet pipeline can flow to the right through the opening and closing hole 33 to the water outlet connector 3. When the water flow flows to the right through the opening and closing hole 33, the water flow pushes the check plate 38 to the right by using the pressure of the water flow. The check plate 38 under pressure swings upward around the hinge shaft 43. At this moment, the check plate 38 no longer blocks and seals the right end hole of the check hole 37, and the water flow can flow to the water outlet connector 3 and finally flow into the water outlet pipeline or the faucet nozzle and the like for use. If the reverse flow occurs during the use of the anti-freezing device, the pressure applied to the check plate 38 to the right will suddenly decrease. At this moment, the check plate 38 falls back to the original position under the action of gravity and blocks and seals the right end hole of the check hole 37 again, so that the reverse flow cannot flow to the water inlet connector 2, effectively achieving the effect of checking the flow.
[0048] The rear shaft hole 39 is located above the check hole 37, and the outer wall of the front side of the valve body 1 is provided with a positioning screw hole 40 coaxial with the rear shaft hole 39.

The positioning screw hole 40 is screwed with a positioning screw 42 matched therewith. The rear shaft hole 39 is provided with a hinge shaft 43 matched therewith. The front end of the hinge shaft 43 penetrates into the positioning screw hole 40 through the front shaft hole 41 and presses on the positioning screw 42. The upper end of the check plate 38 is provided with a hinge arm 44, and the hinge arm 44 is provided with a hinge hole 45 matched with the hinge shaft 43. This fixing mode is convenient for disassembling the hinge shaft 43 and the check plate 38.
[0049] The upper surface of the valve body 1 is provided with a mounting hole 46 which is in communication with the swing cavity 36. A sealing cover 47 which is matched with the mounting hole 46 is screwed in the mounting hole 46. The sealing cover 47 is only needed to be screwed out, and then the components in the swing cavity 36 can be operated through the mounting hole 46, so that the components in the swing cavity 36 are convenient to disassemble and assemble.
[0050] When the anti-freezing device is not needed to be used, the valve rod 34 is only needed to be rotated through the handle 35, and the valve rod 34 drives the valve ball 32 to rotate synchronously, so that the rotation of the opening and closing hole 33 is realized. When the valve ball 32 rotates by ninety degrees, the two end orifices of the opening and closing hole 33 are changed from the original left and right direction to the front and back direction. At this time, the two end orifices of the opening and closing hole are shielded and sealed by the cavity wall of the opening and closing cavity 31. The water flow which flows to the right in the water inlet pipeline is directly intercepted in the water inlet connector 2 and cannot flow to the water outlet connector, so that the effect of intercepting the flow is realized.
