[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 A dual-purpose temperature control valve comprises a valve body 1, the inner cavity of the valve body 1 is fixedly equipped with a connecting chamber 2, the outer wall of the valve body 1 is fixedly equipped with a valve chamber 3, the inner cavity of the valve chamber 3 is provided with a movable groove 4, the inner wall of the movable groove 4 is fixedly equipped with a vertical rod 5, the outer wall of the vertical rod 5 is movably sleeved with a top spring 6, the outer wall of the top spring 6 is movably sleeved with a movable plate 7, the inner cavity of the movable plate 7 is rotatably connected with a valve stem 8, the outer edge of the valve stem 8 is fixedly equipped with a plug 9, the top of the inner cavity of the valve chamber 3 is fixedly equipped with an expansion chamber 10, the inner cavity of the expansion chamber 10 is movably sleeved with a push rod 11, the outer edge of the push rod 11 is fixedly equipped with a limit plate 12, and the outer wall of the expansion chamber 10 is fixedly equipped with a connecting pipe 13.

[0022] By opening a movable groove 4 in the inner cavity of the valve chamber 3 and installing a vertical rod 5 on the inner wall of the movable groove 4, the movable plate 7 can move up and down on the outer wall of the vertical rod 5, thereby driving the valve stem 8 to move up and down during the up and down movement of the movable plate 7, thereby achieving a blocking effect on the inner cavity of the connecting chamber 2 during the up and down movement of the valve stem 8, thereby achieving an effect of controlling the flow rate.

[0023] In a preferred embodiment, the static length of the top spring 6 matches the length of the vertical rod 5, and the top spring 6 is made of high-carbon steel.

[0024] By setting a top spring 6 on the outer wall of the vertical rod 5, a certain supporting force can be provided for the movable plate 7 under the action of the top spring 6, and the movable plate 7 can be supported under the action of the top spring 6, so that the movable plate 7 can quickly restore to its original state, and then the movable plate 7 drives the valve stem 8 and the plugging head 9 to move upward from the inner cavity of the connecting chamber 2.

[0025] In a preferred embodiment, the outer wall diameter of the movable plate 7 is equal to the inner wall diameter of the movable groove 4 , and the outer wall diameter of the movable plate 7 is larger than the inner wall diameter of the valve chamber 3 .

[0026] By setting a movable plate 7 on the outer wall of the vertical rod 5, a valve stem 8 is rotated in the inner cavity of the movable plate 7. When the valve stem 8 moves downward under the action of the limit plate 12 and the push rod 11, the movable plate 7 will be driven to move downward along the inner wall of the movable groove 4. When the movable plate 7 moves downward along the inner wall of the movable groove 4, the top spring 6 will be compressed, so that the plugging head 9 on the outer edge of the valve stem 8 enters the inner cavity of the connecting chamber 2, thereby achieving a sealing effect on the inner cavity of the connecting chamber 2.

[0027] In a preferred embodiment, the inner cavity of the push rod 11 is filled with paraffin, and the outer edge of the limit plate 12 passes through the outer wall of the push rod 11 and contacts the outer wall of the valve stem 8 .

[0028] By filling the paraffin in the inner cavity of the push rod 11, the paraffin will expand when heated. At this time, the paraffin in the inner cavity of the push rod 11 will expand, thereby pushing the limit plate 12 to move downward along the inner wall of the push rod 11. In the process of the limit plate 12 pushing the valve stem 8 to move downward, the plugging head 9 is pushed into the inner cavity of the connecting chamber 2, thereby achieving a sealing effect.

[0029] In a preferred embodiment: the end of the connecting pipe 13 away from the expansion chamber 10 passes through the outer wall of the valve body 1 and enters the inner cavity of the valve body 1 , and the outer edge diameter of the connecting chamber 2 close to the connecting pipe 13 matches the inner cavity diameter of the valve body 1 .

[0030] Through the connecting pipe 13 arranged on the outer wall of the valve body 1, the valve body 1 has a water outlet near one end of the connecting pipe 13. The temperature of the water outlet will be transferred to the inner cavity of the push rod 11 through the connecting pipe 13. When the temperature in the valve body 1 near one end of the connecting pipe 13 is too high, the heat will be transferred to the inner cavity of the push rod 11 through the connecting pipe 13, and then the valve stem 8 will be pushed to move under the action of the paraffin in the inner cavity of the push rod 11.

[0031] In a preferred embodiment: a rubber sealing ring is fixedly mounted on the outer wall of the plugging head 9, a water outlet is opened in the inner cavity of the connecting chamber 2, and the outer wall diameter of the plugging head 9 matches the inner wall diameter of the water outlet.

[0032] By means of the rubber sealing ring arranged on the outer wall of the plugging head 9, when the valve stem 8 moves downward under the action of the expansion of the paraffin in the inner cavity of the push rod 11, the plugging head 9 will enter the water outlet hole in the inner cavity of the connecting chamber 2 under the action of the valve stem 8, thereby sealing the connecting chamber 2, thereby preventing the hot water in the side of the valve body 1 away from the connecting pipe 13 from continuing to pass through the connecting chamber 2, thereby achieving the effect of controlling the temperature in the inner cavity on the side of the valve body 1 close to the connecting pipe 13.

[0033] Working principle: When the above-mentioned device is in use, the outer wall of the valve body 1 away from the connecting pipe 13 is connected to the hot water inlet pipe. At this time, hot water can smoothly pass through the inner cavity of the valve body 1 and enter the inner cavity of the valve body 1 close to the connecting pipe 13. Once hot water continues to enter the inner cavity of the valve body 1 close to the connecting pipe 13 through the connecting chamber 2, when the temperature in the inner cavity of the valve body 1 close to the connecting pipe 13 is too high, the temperature will be transferred to the inner cavity of the push rod 11 under the action of the connecting pipe 13, so that the paraffin in the inner cavity of the push rod 11 will expand due to the heat, thereby pushing the limit plate 12 along the push rod during the expansion of the paraffin. The inner wall of 11 moves downward, so that the valve stem 8 can be pushed by the expansion of paraffin, so that the valve stem 8 moves downward and the inner cavity of the connecting chamber 2 is blocked under the action of the plugging head 9, thereby preventing hot water from continuing to pass through the connecting chamber 2. Once the temperature of the valve body 1 close to the connecting pipe 13 side drops, the paraffin in the inner cavity of the push rod 11 expands and shrinks. At this time, the valve stem 8 and the plugging head 9 will return to their original state under the action of the top spring 6, so that the hot water on the side of the valve body 1 away from the connecting pipe 13 passes through the connecting chamber 2, thereby restricting the circulation of hot water under the action of the valve stem 8 and the plugging head 9, thereby controlling the temperature.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
