[0024] Embodiment 1

[0025] As Figures 1-4The utility model provides a kind of technical scheme shown in the utility model discloses an automobile air-conditioning warm air valve, comprising: flow limiting mechanism 1, one end of flow limiting mechanism 1 is provided with buffer mechanism 2, flow limiting mechanism 1 includes frame plate 11, the inner wall of frame plate 11 is provided with water tank one 12 and water tank two 116 respectively, the inner wall of frame plate 11 is in contact with one side of water tank one 12 and water tank two 116, one end of water tank one 12 is provided with connecting pipe 13, one end of water tank one 12 is fixedly communicated with one end of connecting pipe 13, the other end of connecting pipe 13 is provided with valve cavity 14, the other end of connecting pipe 13 is fixedly communicated with one end of valve cavity 14, the inner wall of valve cavity 14 is provided with baffle plate 16, the inner wall of valve cavity 14 is vertically combined with the outside of baffle plate 16, the bottom side of baffle plate 16 is provided with spring one 110, the bottom side of baffle plate 16 is fixedly connected with the top end of spring one 110, the bottom end of spring one 110 is provided with sleeve 15, the bottom end of spring one 110 is fixedly connected with the inner wall of sleeve 15, the inner wall of water tank one 12 is provided with push rod 19, the inner wall of water tank one 12 is fixedly connected with the outside of one end of push rod 19, the other end of push rod 19 is fixedly contacted with one end of the top side of baffle plate 16, the bottom side of baffle plate 16 is provided with inner tube 112, the bottom side of baffle plate 16 is fixedly connected with the top end of inner tube 112, the bottom end outside of inner tube 112 is provided with outer tube 111, the bottom end outside of inner tube 112 is vertically combined with the inner wall of outer tube 111, the bottom end of outer tube 111 is fixedly connected with the inner wall of sleeve 15, the bottom end of sleeve 15 is provided with radiating water pipe 115, the bottom end of sleeve 15 is fixedly communicated with the top side of radiating water pipe 115, the bottom side of radiating water pipe 115 is fixedly communicated with one end of water tank two 116, one end of water tank one 12 is provided with controller 113, one end of water tank one 12 is fixedly connected with one side of controller 113, one side of radiating water pipe 115 is provided with temperature sensor 114, one side of radiating water pipe 115 is fixedly connected with one side of temperature sensor 114.

[0026] In the embodiment, when the automobile air-conditioning warm air valve is used, the push rod 19 is lengthened, the baffle plate 16 moves in the original position under pressure, and is forced to retreat into the sleeve 15. At this time, the liquid in the water tank one 12 flows through the open channel, and then enters the radiating water pipe 115 and transmits heat to the cab. When the temperature in the cab reaches the preselected setting, the temperature controller 113 sends a command to the controller 113, which controls the operation of the push rod 19. Then, under the action of the controller 113, the push rod 19 gradually retracts, and the spring one 110 is not under pressure and releases, returning the baffle plate 16 to the original position and sealing the channel again. Since the flow of coolant can be accurately controlled as needed, this valve design can effectively save energy. When the temperature in the cab reaches the preselected temperature, the system can quickly close or reduce the flow of coolant, avoiding unnecessary energy consumption.

[0027] Secondly, in the process of moving the blocking plate 16, the inner tube 112 will slide in the outer tube 111, and the sliding design of the inner tube 112 in the outer tube 111 can effectively guide the blocking plate 16 to move vertically, which ensures that the blocking plate 16 can completely block or open the channel, thereby accurately controlling the flow of the coolant, avoiding the blocking plate 16 from being skewed or jammed during movement, and ensuring the stability and reliability of the valve operation.

[0028] Embodiment 2

[0030] In this embodiment, secondly, the vehicle will encounter bumpy sections during driving, therefore, the female tube 23 and the sub-tube 21 are arranged on the inner side of the frame plate 11, and the spring 22 is installed between the two, since one end of the sub-tube 21 is connected with the water tank one 12 and the water tank two 116 respectively, the spring can absorb and alleviate the impact and vibration when the vehicle passes through the bumpy sections.
