By adjusting the position of the rotating shaft moving and rotating, the rotation of the valve core is realized through the shaft linkage structure.

Specific embodiments

[0038] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0039] Embodiment 1:

[0040] Such as Figures 1 to 8As shown, a two-way air outlet simple valve capable of safe temperature control comprises a first valve body 1, a second valve body 2, a valve core 50, a rotating shaft 3, a shaft linkage structure 4, a conjoined valve cover 5, a first air outlet portion 7, a second air outlet portion 8 and a flameout temperature control package 6. The first valve body 1 is connected to the second valve body 2; the first valve body 1 has an air inlet 11, an air inlet cavity 12 and a valve core cavity 13 which are connected in sequence; the valve core 50 can be adapted to be rotatably installed in the valve core cavity 13 and is connected to the air inlet cavity 12; the second valve body 2 has an installation cavity 21 which is connected in sequence and an air guide cavity 22 which can be connected to the valve core 50; the rotating shaft 3 is transmission-connected to the valve core 50 through the shaft linkage structure 4; the rotating shaft 3 is connected to the shaft linkage structure 4 corresponding to the position of the second valve body 2 and can reciprocate in the front-rear direction relative to the second valve body 2; the conjoined valve cover 5 is sleeved on the rotating shaft 3 and is respectively connected to the first valve body 1 and the second valve body 2, and is used to cover the shaft linkage structure 4. The connecting valve cover has a second slot 52 and a first slot 51 on the left and right sides relative to the rotating shaft 3; the first air outlet 7 is connected to the first valve body 1 and can be connected to the valve core 50; the flameout temperature control package 6 is installed in the installation cavity 21, and is used to open or close the connection between the air guide cavity 22 and the installation cavity 21; the second air outlet 8 is connected to the second valve body 2 and is connected to the installation cavity 21; when the rotating shaft 3 moves and rotates to be inserted into the first slot 51, the valve core 50 is connected to the first air outlet 7; when the rotating shaft 3 moves and rotates to be inserted into the second slot 52, the valve core 50 is connected to the air guide cavity 22.

[0041] The simple two-way air outlet valve with safe temperature control is combined by arranging a first valve body 1, a second valve body 2, a valve core 50, a rotating shaft 3, a shaft linkage structure 4, a conjoined valve cover 5, a first air outlet portion 7, a flameout temperature control package 6, and a second air outlet portion 8. The rotation of the valve core 50 is achieved through the shaft linkage structure 4 by adjusting the moving and rotating position of the rotating shaft 3. When the rotating shaft 3 moves and rotates to snap into the first clamping groove 51, the valve core 50 is connected to the first air outlet portion 7; when the rotating shaft 3 moves and rotates to snap into the second clamping groove 52, the valve core 50 is connected to the air guide cavity 22; in this way, the first air outlet portion 7 and the second air outlet portion 8 can achieve the effect that the simple valve can have two-way air outlet, the structure is simple, the operation is convenient, the flexibility of use is improved, and it is more convenient to use. The requirements of various application scenarios can be better met. Even if the air outlet of one air outlet fails or is blocked, the air outlet of the other air outlet can continue to work normally, thereby reducing the pressure on a single air outlet and reducing the safety hazards caused by excessive pressure. Moreover, by combining the flameout temperature control package 6 and the valve core 50, when the flameout temperature control package 6 senses the external temperature, when the sensed temperature is higher than the preset value, the flameout temperature control package 6 can close the connection between the gas guide cavity 22 and the installation cavity 21 due to thermal expansion and contraction, and quickly close the gas flow, which is convenient for users to use, and has high safety performance, ensuring that the gas supply can be cut off in time when the temperature is abnormal, so as to better ensure the continuity, stability and safety of the gas supply.

[0042] The simple two-way air outlet valve with safe temperature control also includes a push rod 40, which is slidably connected to the rotating shaft 3 and connected to the flameout temperature control package 6, and is used to push the flameout temperature control package 6 to open the connection between the air guide cavity 22 and the installation cavity 21. When the rotating shaft 3 rotates and moves relative to the front of the second valve body 2 to open the first air outlet 7 or the second air outlet 8, the push rod 40 moves synchronously to the front of the second valve body 2 under the movement and pressure of the rotating shaft 3, pushing the flameout temperature control package 6, and the top pressure triggers the flameout temperature control package 6 to open the connection between the air guide cavity 22 and the installation cavity 21, that is, the air guide cavity 22, the installation cavity 21, and the second air outlet 8 are connected to open the second air outlet 8. Of course, it should be noted that when the valve core 50 is not connected to the air guide cavity 22, that is, when the rotating shaft 3 is not inserted into the second slot 52, the second air outlet 8 cannot discharge gas. This design can effectively trigger the flameout temperature control package 6 to work, monitor the temperature outside the flameout temperature control package 6 in real time, play a good role in temperature monitoring, and quickly control and shut down the gas flow when abnormal temperature is detected. It has high safety performance and ensures that the gas supply can be cut off in time when the temperature is abnormal, so as to better ensure the continuity, stability and safety of gas supply.

[0043] In this embodiment, the flameout temperature control package 6 has a temperature sensing probe 61 and an elastic seal 62; the elastic seal 62 is installed in the installation cavity 21 and connected to the ejector rod 40, and is used to open or close the communication between the air guide cavity 22 and the installation cavity 21; the temperature sensing probe 61 is connected to the elastic seal 62 and extends outside the front end of the second valve body 2. First, the ejector rod 40 is used to press the elastic seal 62 to trigger the power-on operation of the flameout temperature control package 6, and then the temperature sensing probe 61 is used to sense the temperature outside it. When the sensed temperature is higher than the preset value, the temperature sensing probe 61 can push the elastic seal 62 to close the communication between the air guide cavity 22 and the installation cavity 21 due to thermal expansion and contraction, quickly closing the gas flow, with high safety performance, ensuring that the gas supply can be cut off in time in case of abnormal temperature, and better guaranteeing the continuity, stability and use safety of the gas supply.

[0044] In this embodiment, a sliding groove 31 for the ejector rod 40 to slide and embed is provided on the front end of the rotating shaft 3. During the process of the rotating shaft 3 moving forward towards the second valve body 2, the ejector rod 40 first moves relatively in the sliding groove 31. After the ejector rod 40 contacts the bottom of the sliding groove 31, it pushes the ejector rod 40 to move synchronously. The ejector rod 40 presses the elastic seal 62 to trigger the power-on operation of the flameout temperature control package 6 and open the communication between the air guide cavity 22 and the installation cavity 21; when the temperature sensing probe 61 senses the temperature outside it, and when the sensed temperature is higher than the preset value, the temperature sensing probe 61 can push the elastic seal 62 to close the communication between the air guide cavity 22 and the installation cavity 21 due to thermal expansion and contraction. At the same time, the elastic seal 62 pushes the ejector rod 40 and the rotating shaft 3 to move in the reverse direction, realizing the closing of the communication between the air guide cavity 22 and the installation cavity 21, with a simple structure and convenient operation.

[0045] In order to better realize the stable clamping of the rotating shaft 3 into the first clamping groove 51 or the second clamping groove 52, a shaft clamping portion 32 that can be clamped into the first clamping groove 51 and the second clamping groove 52 and is located outside the combined valve cover 5 is provided on the rotating shaft 3.

[0046] Preferably, the groove side walls of the first clamping groove 51 close to the rotating shaft 3 and the groove side walls of the second clamping groove 52 close to the rotating shaft 3 are both inclined surfaces for the rotating shaft 3 to slide into. In this way, by designing the inclined surfaces in the first clamping groove 51 and the second clamping groove 52, the shaft clamping portion 32 of the rotating shaft 3 can be more conveniently slid into the first clamping groove 51 or the second clamping groove 52.

[0047] In this embodiment, the shaft linkage structure 4 includes a main gear disk 41 and a sub-gear disk 42; the main gear disk 41 and the sub-gear disk 42 are respectively rotatably connected to the second valve body 2 and the first valve body 1; the main gear disk 41 and the sub-gear disk 42 are meshed with each other; the main gear disk 41 is slidably sleeved on the rotating shaft 3 and rotates synchronously with the rotating shaft 3; the valve core 50 is connected to the sub-gear disk 42 and can rotate synchronously with the sub-gear disk 42. By designing the main gear disk 41 and the sub-gear disk 42 to form the shaft linkage structure 4, when the rotating shaft 3 rotates, the main gear disk 41 and the sub-gear disk 42 rotate synchronously with the rotating shaft 3, and then drive the valve core 50 to rotate, which can effectively realize the rotation of the valve core 50, so that the first gas outlet 7 and the second gas outlet 8 can be correspondingly communicated with the valve core 50, and stable gas supply of the first gas outlet 7 and the second gas outlet 8 can be realized.

[0048] In this embodiment, the distance between the central axis of the air inlet 11 and the rear end face of the integral valve cover 5 is L; the distance L is 30 - 37 mm. Preferably, the distance L can be 30 mm, 33 mm, or 36 mm. By designing the distance between the central axis of the air inlet 11 and the rear end face of the integral valve cover 5 within the range of 30 - 37 mm, the dimensional range of key components can be precisely controlled in the front-back direction of the first valve body 1, which can effectively define the dimensions of the first valve body 1, the second valve body 2, the valve core 50, the rotating shaft 3, the shaft linkage structure 4, the integral valve cover 5, the first gas outlet 7, the second gas outlet 8, and the flameout temperature control package 6, better optimize the design layout, make the overall structure of the simple valve more compact, achieve a miniaturized design in terms of volume, avoid excessive space occupation by the structure, be able to easily adapt to various narrow installation environments, better cooperate with other gas valves on gas equipment, improve the space utilization rate. At the same time, the manufacturing cost factor, reduction of material usage, and simplification of the production process are fully considered, all of which effectively reduce the manufacturing cost and are more suitable for promotion in the market.

[0049] Embodiment 2:

[0050] In Embodiment 2, as Figures 1 to 7As shown, the two-way air outlet simple valve with safe temperature control in this embodiment is basically the same as that in Embodiment 1. The difference lies in that the two-way air outlet simple valve with safe temperature control further includes a solenoid valve assembly 9 electrically connected to the flameout temperature control package 6. The solenoid valve assembly 9 is installed in the intake cavity 12 and is used to open or close the connection between the intake cavity 12 and the valve core 50. In this embodiment, on the basis of Embodiment 1, a solenoid valve assembly 9 is added, and the combination of double protection of the flameout temperature control package 6 and the solenoid valve assembly 9 is adopted to achieve the effect of double safety protection. When the flameout temperature control package 6 senses the external temperature and the sensed temperature is higher than the preset value, it feeds back to the solenoid valve assembly 9. The flameout temperature control package 6 can close the connection between the air guide cavity 22 and the installation cavity 21 due to thermal expansion and contraction. At this time, the solenoid valve assembly 9 also works, quickly closes the connection between the intake cavity 12 and the valve core 50, quickly closes the gas flow of the first air outlet part 7 and the second air outlet part 8, improves the use safety of the simple valve, better ensures that the gas supply can be cut off in time under abnormal temperature conditions, and better guarantees the continuity, stability and use safety of the gas supply.

[0051] In this embodiment, according to the design of the solenoid valve assembly 9, the bidirectional air outlet type simple valve with safe temperature control further includes a sliding rod 10, a lever pressing piece 20, and a pushing piece 30; one end of the lever pressing piece 20 is sleeved on the rotating shaft 3 and connected to the rear end of the second valve body 2, and the other end extends to the rear end of the first valve body 1; the rear end of the sliding rod 10 is connected to the lever pressing piece 20, and the front end of the sliding rod 10 can slide through the valve body, and the front end of the valve core cavity 13 is connected to the solenoid valve assembly 9, and is used to push and press the solenoid valve assembly 9 to open the communication between the air inlet cavity 12 and the valve core cavity 13. At this time, under the pushing of the sliding rod 10, the solenoid valve assembly 9 is triggered to energize and work. The pushing piece 30 is sleeved on the rotating shaft 3 and is located behind the lever pressing piece 20, and moves forward with the rotating shaft 3 towards the second valve body 2 to push and press the lever pressing piece 20. By designing the bidirectional air outlet type simple valve with safe temperature control in this way, when it is necessary to open the first air outlet part 7 or the second air outlet part 8, during the process of the rotating shaft 3 moving forward towards the second valve body 2, the pushing piece 30 pushes and presses the lever pressing piece 20, and the other end of the lever pressing piece 20 is pushed, so that the sliding rod 10 passes through the front end of the valve body and the valve core cavity 13, and pushes and presses the solenoid valve assembly 9 to open the communication between the air inlet cavity 12 and the valve core cavity 13, realizing the communication between the air inlet cavity 12 and the valve core 50. When the flameout temperature control package 6 senses the external temperature and the sensed temperature is higher than the preset value, it feeds back to the solenoid valve assembly 9. The flameout temperature control package 6 can close the communication between the air guide cavity 22 and the installation cavity 21 due to thermal expansion and contraction. At this time, the solenoid valve assembly 9 also works, pushing the sliding rod 10 to reset, quickly closing the communication between the air inlet cavity 12 and the valve core 50, preventing the gas from flowing out from the first air outlet part 7 and the second air outlet part 8, improving the use safety of the simple valve, better ensuring that the gas supply can be cut off in time under abnormal temperature conditions, and better guaranteeing the continuity, stability and use safety of the gas supply, achieving the effect of double safety protection.

[0052] In Embodiment 2, the working process of the present utility model is as follows:

[0053] In use, when it is necessary to open the first air outlet 7, the rotating shaft 3 is adjusted to move and rotate. The shaft clamping portion 32 is clamped into the first clamping groove 51, and the main gear disk 41 and the auxiliary gear disk 42 rotate synchronously with the rotating shaft 3, thereby driving the valve core 50 to rotate, so that the valve core 50 is communicated with the first air outlet 7. At this time, when the rotating shaft 3 rotates and moves forward relative to the front of the second valve body 2, the ejector rod 40 moves forward synchronously with the second valve body 2 under the pushing pressure of the movement of the rotating shaft 3, pushing the flameout temperature control package 6, and pressing to trigger the flameout temperature control package 6 to open the communication between the air guide cavity 22 and the installation cavity 21, and the flameout temperature control package 6 is powered on for operation; and during the process of the rotating shaft 3 moving forward relative to the front of the second valve body 2, the pushing piece 30 pushes the lever pressing piece 20, and the other end of the lever pressing piece 20 is pushed, so that the sliding rod 10 passes through the front end of the valve body and the valve core cavity 13, and presses the solenoid valve assembly 9 to open the communication between the air inlet cavity 12 and the valve core cavity 13, realizing the communication between the air inlet cavity 12 and the valve core 50, and the solenoid valve is powered on for operation; then the gas sequentially passes through the air inlet 11, the air inlet cavity 12, the inner cavity of the valve core 50, and finally flows out from the first air outlet part.

[0054] When it is necessary to open the second air outlet 8, the rotating shaft 3 is adjusted to move and rotate. The shaft clamping portion 32 is clamped into the second clamping groove 52, and the main gear disk 41 and the auxiliary gear disk 42 rotate synchronously with the rotating shaft 3, thereby driving the valve core 50 to rotate, so that the valve core 50 is communicated with the air guide cavity 22. At this time, when the rotating shaft 3 rotates and moves forward relative to the front of the second valve body 2, the ejector rod 40 moves forward synchronously with the second valve body 2 under the pushing pressure of the movement of the rotating shaft 3, pushing the flameout temperature control package 6, and pressing to trigger the flameout temperature control package 6 to open the communication between the air guide cavity 22 and the installation cavity 21, and the flameout temperature control package 6 is powered on for operation. At the same time, the valve core 50, the air guide cavity 22, the installation cavity 21, and the second air outlet 8 are communicated with each other, and the second air outlet 8 is opened; and during the process of the rotating shaft 3 moving forward relative to the front of the second valve body 2, the pushing piece 30 pushes the lever pressing piece 20, and the other end of the lever pressing piece 20 is pushed, so that the sliding rod 10 passes through the front end of the valve body and the valve core cavity 13, and presses the solenoid valve assembly 9 to open the communication between the air inlet cavity 12 and the valve core cavity 13, realizing the communication between the air inlet cavity 12 and the valve core 50, and the solenoid valve is powered on for operation; then the gas sequentially passes through the air inlet 11, the air inlet cavity 12, the inner cavity of the valve core 50, the air guide cavity 22, the installation cavity 21, and finally flows out from the second air outlet part.

[0055] When a temperature anomaly occurs, the temperature sensing probe 61 senses the external temperature. When the sensed temperature is higher than the preset value, the temperature sensing probe 61 can push the elastic seal 62 due to thermal expansion and contraction. The elastic seal 62 reversely pushes the ejector rod 40 and the rotating shaft 3 to move, realizing the closing of the connection between the air guide cavity 22 and the installation cavity 21, quickly closing the gas flow, and sending a closing signal to the solenoid valve assembly 9. At this time, the solenoid valve assembly 9 also operates, pressing the sliding rod 10 to reset, quickly closing the connection between the air intake cavity 12 and the valve core 50, preventing the gas from flowing out from the first air outlet part 7 and the second air outlet part 8, improving the safety of using this simple valve, better ensuring that the gas supply can be cut off in time under abnormal temperature conditions, and better guaranteeing the continuity, stability and safety of gas supply, achieving the effect of double safety protection.

[0056] In summary, the embodiment of the present invention provides a bidirectional air outlet type simple valve with temperature safety control. Among them, the bidirectional air outlet type simple valve with temperature safety control has the following advantages:

[0057] First, by combining the first valve body 1, the second valve body 2, the valve core 50, the rotating shaft 3, the shaft linkage structure 4, the integral valve cover 5, the first air outlet part 7, the flameout temperature control package 6, and the second air outlet part 8, by adjusting the moving and rotating positions of the rotating shaft 3, the rotation of the valve core 50 is realized through the shaft linkage structure 4. When the rotating shaft 3 moves and rotates and is stuck in the first card slot 51, the valve core 50 is connected to the first air outlet part 7; when the rotating shaft 3 moves and rotates and is stuck in the second card slot 52, the valve core 50 is connected to the air guide cavity 22; in this way, the first air outlet part 7 and the second air outlet part 8 can achieve the effect that this simple valve can have bidirectional air outlet, with a simple structure, convenient operation, improved flexibility in use, better meeting the requirements of various application scenarios. Even when the air outlet of one air outlet part fails or is blocked, the air outlet of the other air outlet part can still continue to work normally, reducing the pressure borne by a single air outlet part and reducing potential safety hazards caused by excessive pressure; and then by combining the flameout temperature control package 6 and the valve core 50 together, when the flameout temperature control package 6 senses the external temperature, when the sensed temperature is higher than the preset value, the flameout temperature control package 6 can close the connection between the air guide cavity 22 and the installation cavity 21 due to thermal expansion and contraction, quickly closing the gas flow, which is convenient for users to use and has high safety performance, ensuring that the gas supply can be cut off in time under abnormal temperature conditions, and better guaranteeing the continuity, stability and safety of gas supply.

[0058] II. Based on the first valve body 1, the second valve body 2, the valve core 50, the rotating shaft 3, the shaft linkage structure 4, the integral valve cover 5, the first air outlet part 7 and the second air outlet part 8, the combination of the flameout temperature control package 6 and the solenoid valve assembly 9 is adopted to achieve the effect of double safety protection. When the flameout temperature control package 6 senses the external temperature and the sensed temperature is higher than the preset value, it feeds back to the solenoid valve assembly 9. The flameout temperature control package 6 can close the connection between the air guide cavity 22 and the installation cavity 21 due to thermal expansion and contraction. At this time, the solenoid valve assembly 9 also works and quickly closes the connection between the air inlet cavity 12 and the valve core 50, quickly closing the gas flow of the first air outlet part 7 and the second air outlet part 8, improving the use safety of this simple valve, better ensuring that the gas supply can be cut off in time under abnormal temperature conditions, and better guaranteeing the continuity, stability and use safety of the gas supply.

[0059] III. Control the distance between the central axis of the air inlet 11 and the rear end face of the integral valve cover 5 within the range of 30 - 37 mm. In this way, the dimensional range of key components can be accurately controlled in the front-back direction of the first valve body 1, which can effectively define the dimensions of the first valve body 1, the second valve body 2, the valve core 50, the rotating shaft 3, the shaft linkage structure 4, the integral valve cover 5, the first air outlet part 7, the second air outlet part 8, the flameout temperature control package 6 and the solenoid valve assembly 9, better optimize the design layout, make the overall structure of this simple valve more compact, with a miniaturized volume design, avoid excessive space occupation by the structure, be able to easily adapt to various narrow installation environments, better cooperate with other gas valves on gas equipment, improve the space utilization rate. At the same time, the manufacturing cost factor, the reduction of material usage and the simplification of the production process are fully considered, all of which effectively reduce the manufacturing cost and are more suitable for promotion in the market.

[0060] The above are only the preferred embodiments of this application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of this application, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of this application.
