Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas valves, in particular to a gas temperature control valve. BACKGROUND

[0002] The gas temperature control valve generally comprises a valve body, a valve core, a valve rod and a temperature controller. The valve body has a first cavity and a second cavity, and a communication hole between the first cavity and the second cavity. The valve body is provided with an air inlet channel communicating with the first cavity and an air outlet channel communicating with the second cavity. The valve core is movably installed in the first cavity and connected with the valve rod. The valve rod can drive the valve core to rotate to open or close the air inlet channel. The temperature controller is rotatably installed on the valve body by a nut. A sealing rod is arranged between the temperature controller and the valve core. One end of the sealing rod is movably connected with the valve core, and the other end is threadedly connected with the temperature controller. A sealing element is arranged on the outer periphery of the sealing rod below the communication hole. In use, the valve rod is rotated to drive the valve core to open the air inlet channel. When the temperature rises, the temperature controller expands to push the sealing rod to move upwards and make the sealing element move close to the communication hole, thereby adjusting the gas flow.

[0003] Before the gas temperature control valve is shipped, it needs to be tested. When the gas flow in the valve body does not meet the standard, the staff needs to rotate the temperature controller to push the sealing rod to move, so that the sealing element moves close to or away from the communication hole to adjust the size of the communication hole, and then adjusts the gas flow in the valve body to the set value. However, since the temperature controller is generally installed on the valve body by a nut, the nut may loosen during rotation of the temperature controller, resulting in an error in the adjusted position, and thus the gas flow in the gas temperature control valve is incorrect, i.e. the temperature control of the gas temperature control valve is not accurate, and in severe cases it may also cause gas leakage. In addition, the temperature controller is usually at high temperature during adjustment, and it is easy to cause burns to the staff during rotation, which poses a safety hazard. SUMMARY

[0033] Referring to Figures 1 to 5 An embodiment of the present application provides a gas temperature control valve, which comprises a valve body 100, a valve core 150, a temperature controller 400, a sealing rod 300, an adjusting rod 200 and an operation channel 161. The valve body 100 has a first cavity 111 and a second cavity 112 which are independent of each other, and a communication hole 140 between the first cavity 111 and the second cavity 112. The valve body 100 is provided with an inlet channel 120 which is in communication with the first cavity 111 and an outlet channel 130 which is in communication with the second cavity 112. The valve core 150 is movably installed in the first cavity 111 and can rotate to open or close the inlet channel 120. The valve core 150 is connected with a valve rod 160 which extends outside the first cavity 111, and the valve rod 160 can drive the valve core 150 to rotate to open or close the inlet channel 120. The temperature controller 400 is installed on the valve body 100 and extends into the second cavity 112. The sealing rod 300 is threadedly connected with the temperature controller 400, and the sealing rod 300 is provided with a sealing element 310 located in the second cavity 112. The sealing rod 300 can rotate relative to the temperature controller 400, and the sealing rod 300 can also drive the sealing element 310 to move relative to the temperature controller 400 in the up-down direction to open or close the communication hole 140. The adjusting rod 200 movably passes through the valve core 150, and the lower end of the adjusting rod 200 is in transmission connection with the sealing rod 300 and can drive the sealing rod 300 to rotate synchronously. The operation channel 161 is arranged on the valve rod 160 in the axial direction of the valve rod 160, and the vertical projection of the upper end of the adjusting rod 200 is located in the vertical projection of the operation channel 161.

[0034] In the above structure, by arranging the adjusting rod 200 and arranging the operation channel 161 on the valve rod 160, the vertical projection of the upper end of the adjusting rod 200 is located in the vertical projection of the operation channel 161. When it is necessary to adjust the gas flow in the valve body 100, a special tool can be used to operate the adjusting rod 200 through the operation channel 161, to drive the adjusting rod 200 to rotate relative to the valve core 150. The adjusting rod 200 can drive the sealing rod 300 to rotate synchronously, so that the sealing rod 300 drives the sealing element 310 to move relative to the temperature controller 400 in the up-down direction to approach or move away from the communication hole 140. Thus, the opening size of the communication hole 140 can be adjusted, and the gas flow in the valve body 100 can be adjusted. In the adjusting process, the temperature controller 400 does not need to be rotated, but the adjusting rod 200 is operated by the special tool through the operation hole 161 of the valve rod 160. The adjusting is convenient and can reduce the scalding of the operator caused by the temperature controller 400, and has high safety performance.

[0035] The gas temperature control valve described above, in use, can be opened by rotating the valve stem 160 to drive the valve core 150 to rotate synchronously, so that the gas can flow into the first cavity 111 from the gas inlet channel 120, then flow into the second cavity 112 through the communication hole 140, and finally flow to the gas outlet channel 130 from the second cavity 112. The temperature controller 400 can sense the combustion temperature of the burner and move the sealing rod 300 along the up-down direction by thermal expansion and contraction, so that the sealing rod 300 can drive the sealing piece 310 to move along the up-down direction to approach or move away from the communication hole 140, thereby adjusting the opening size of the communication hole 140 and automatically adjusting the gas flow.

[0036] It can be understood that, with reference to Figures 3 to 5 , the vertical projection of the upper end of the adjusting rod 200 is located in the vertical projection of the operation channel 161, so that the staff can directly adjust the adjusting rod 200 through the operation channel 161 on the valve stem 160. Specifically, the upper end of the adjusting rod 200 can be arranged adjacent to the lower end of the operation channel 161, or the upper end of the adjusting rod 200 can extend into the operation channel 161, or the upper end of the adjusting rod 200 can be directly arranged below the operation channel 161 and aligned with the operation channel 161. The position relationship between the adjusting rod 200 and the operation channel 161 is not limited in the present application.

[0037] It can be understood that, with reference to Figures 3 to 5 , the valve core 150 is movably installed in the first cavity 111 and can be rotated to open or close the gas inlet channel 120. Specifically, the valve core 150 is provided with a valve core hole 151 communicating with the first cavity 111, and the gas inlet channel 120 has a gas outlet hole extending to the side wall of the first cavity 111 and communicating with the first cavity 111. The valve core 150 can be rotated relative to the valve body 100 to make the valve core hole 151 and the gas outlet hole of the gas inlet channel 120 communicate with each other or be staggered with each other, thereby realizing the opening or closing of the gas inlet channel 120.

[0038] It can be understood that, with reference to Figures 3 to 5 , the valve body 100 is provided with a gas outlet channel 130 communicating with the second cavity 112. Specifically, the gas outlet channel 130 has a gas inlet hole extending to the inner wall of the second cavity 112 and communicating with the second cavity 112. When the sealing rod 300 drives the sealing piece 310 to move close to the communication hole 140, the gas flow from the first cavity 111 to the second cavity 112 is reduced. When the sealing rod 300 drives the sealing piece 310 to move to close the communication hole 140, the gas temperature control valve is in a closed state, and the gas in the gas inlet channel 120 cannot flow into the gas outlet channel 130.

[0039] It can be understood that, with reference to Figures 3 to 5The valve body 100 has a first cavity 111 and a second cavity 112 independent of each other, and the first cavity 111 and the second cavity 112 are communicated through a communication hole 140, and specifically, the first cavity 111 and the second cavity 112 communicated through the communication hole 140 constitute a valve cavity 110 of the valve body 100.

[0040] With reference to Figures 1 to 5 In some embodiments, a damping member 210 is arranged between the adjusting rod 200 and the valve core 150, and the valve core 150 can drive the adjusting rod 200 to rotate synchronously through the damping member 210.

[0041] In the above structure, the damping member 210 can facilitate the fixation of the adjusting rod 200, and before the gas temperature control valve is shipped, the damping member 210 can prevent the rotation of the adjusting rod 200 in the process of rotating the adjusting rod 200, and the adjusting rod 200 can be rotated only when the force for rotating the adjusting rod 200 is greater than the friction between the adjusting rod 200 and the damping member 210. When the adjusting rod 200 is rotated to the required angle, the damping member 210 can continue to press and fix the adjusting rod 200, so that the adjusting rod 200 stays at the rotated position. Thus, the angle of the adjusting rod 200 can be adjusted by a small angle, and the gas flow in the valve body 100 can be finely adjusted, so that the adjustment of the gas flow is more accurate. When the gas temperature control valve is actually used, the valve rod 160 drives the valve core 150 to rotate to open the gas inlet channel 120, and the valve core 150 can drive the adjusting rod 200 to rotate synchronously through the damping member 210, and the sealing rod 300 can rotate synchronously with the adjusting rod 200, so that the sealing rod 300 can drive the sealing member 310 to move relative to the temperature controller 400 in the up-down direction to open the communication hole 140. Thus, the gas in the gas inlet channel 120 can flow smoothly to the gas outlet channel 130. As can be seen, when the gas temperature control valve of the embodiment is actually used, the valve rod 160 can not only open the gas inlet channel 120, but also drive the sealing member 310 to open the communication hole 140 through the adjusting rod 200, so as to realize the double control of the gas temperature control valve, and further avoid the occurrence of gas leakage and the like, so that the use of the gas temperature control valve is safer.

[0042] It can be understood that the damping member 210 can be specifically selected from flexible metal members or engineering plastics, such as copper, plastic steel, etc., and the present application does not make specific limitations thereto.

[0043] With reference to Figures 1 to 5 In some embodiments, a limiting structure is arranged between the adjusting rod 200 and the damping member 210, the limiting structure comprises a protruding portion 230 arranged on the outer periphery of the adjusting rod 200 and a first limiting portion 220 arranged on the damping member 210, and the protruding portion 230 is located above the first limiting portion 220 and abuts against the first limiting portion 220.

[0044] In the above structure, the first limiting portion 220 of the damping member 210 can abut against the protruding portion 230 to prevent the adjusting rod 200 from moving downward and disengaging from the valve core 150, thereby better fixing and limiting the adjusting rod 200, and making the connection between the adjusting rod 200 and the valve core 150 more stable and compact.

[0045] It can be understood that, referring to Figures 3 to 5 , the first limiting portion 220 can be a tapered surface arranged along the circumference of the damping member 210 and gradually reduced from top to bottom, and the protruding portion 230 of the outer circumference of the adjusting rod 200 can abut against the tapered surface. Alternatively, the first limiting portion 220 can be directly protrudingly arranged on the inner circumferential wall of the damping member 210, which is not limited in the present application.

[0046] It can be understood that the protruding portion 230 can be arranged around the outer circumference of the adjusting rod 200, or the circumferential wall of the adjusting rod 200 can be provided with a plurality of protruding portions 230, and all the protruding portions 230 are arranged in sequence along the circumferential direction of the adjusting rod 200, which is not limited in the present application.

[0047] Referring to Figures 3 to 5 , in some embodiments, a sealing ring is further arranged between the adjusting rod 200 and the valve core 150, which can prevent the gas in the valve body 100 from flowing into the operation channel 161 of the valve rod 160 through the gap between the adjusting rod 200 and the valve core 150, thereby preventing gas leakage and improving the safety performance of the gas temperature control valve. In addition, the sealing ring can be partially embedded in the outer circumferential wall of the adjusting rod 200, thereby further fixing and limiting the adjusting rod 200, so as to prevent the adjusting rod 200 from moving relative to the valve core 150 along the axial direction and disengaging from the valve core 150.

[0048] Referring to Figures 3 to 5 , in some embodiments, the valve core 150, the valve rod 160, the sealing rod 300 and the adjusting rod 200 are coaxially arranged.

[0049] In the above structure, by coaxially arranging the valve core 150, the valve rod 160, the sealing rod 300 and the adjusting rod 200, the linkage between the components can be facilitated, the probability of failure of each component during movement can be reduced, the durability of the gas temperature control valve can be improved, and the service life of the gas temperature control valve can be prolonged.

[0050] Referring to Figures 3 to 5 , in some embodiments, the upper end of the adjusting rod 200 is provided with an adjusting groove 240 capable of cooperating with a screwdriver.

[0051] In the above structure, the adjusting groove 240 is arranged at the upper end of the adjusting rod 200, which can be matched with a screwdriver. Thus, the worker can directly use the screwdriver to extend into the operation channel 161 of the valve rod 160 and align the adjusting groove 240 at the upper end of the adjusting rod 200, and then rotate the adjusting rod 200 through the screwdriver. Thus, in order to rotate the adjusting rod 200, only the adjusting groove 240 matched with the screwdriver is arranged at the upper end of the adjusting rod 200, which is simple in structure and convenient to operate.

[0052] It can be understood that the adjusting groove 240 on the adjusting rod 200 can be a straight groove suitable for a straight screwdriver, or can be a cross groove suitable for a cross screwdriver, which is not limited in the present application.

[0053] Referring to Figures 3 to 5 In some embodiments, the upper end of the sealing rod 300 is provided with an insertion groove 320, and the lower end of the adjusting rod 200 is movably inserted into the insertion groove 320, so that the sealing rod 300 can move up and down relative to the adjusting rod 200.

[0054] In the above structure, the sealing rod 300 can move up and down relative to the adjusting rod 200, and the adjusting rod 200 can drive the sealing rod 300 to rotate synchronously. Thus, when the sealing rod 300 drives the sealing member 310 to move up and down to approach or move away from the communication hole 140, so as to adjust the gas flow in the valve body 100, the adjusting rod 200 can remain in position without moving up and down synchronously with the sealing rod 300, so that the adjusting rod 200 can be fixed more conveniently, and the connection of the adjusting rod 200 is more stable. Specifically, before the gas temperature control valve is shipped, the worker can drive the sealing rod 300 to rotate synchronously by rotating the adjusting rod 200. In this process, the sealing rod 300 can drive the sealing member 310 to move up and down relative to the adjusting rod 200 to approach or move away from the communication hole 140, so as to adjust the opening size of the communication hole 140, and then adjust the gas flow in the valve body 100. When the gas temperature control valve is actually used, the thermostat 400 can expand and contract with heat and push the sealing rod 300 to drive the sealing member 310 to move up and down relative to the adjusting rod 200 to approach or move away from the communication hole 140, so as to adjust the gas flow in the valve body 100.

[0055] Referring to Figures 3 to 5 In some embodiments, the peripheral wall of the insertion groove 320 is provided with a clamping groove 330 arranged in the up-down direction, and the outer peripheral wall of the adjusting rod 200 has a clamping block 250 extending into the clamping groove 330, which can move along the clamping groove 330 relative to the sealing rod 300.

[0056] In the above structure, the clamping block 250 and the clamping groove 330 are arranged to cooperate with each other, the clamping block 250 of the outer wall of the adjusting rod 200 is movably inserted into the clamping groove 330 of the wall of the insertion slot 320 of the adjusting rod 200, so that the adjusting rod 200 can drive the sealing rod 300 to rotate synchronously. By arranging the clamping groove 330 in the up-down direction, the clamping block 250 can move along the clamping groove 330 relative to the sealing rod 300, and the sealing rod 300 can move in the up-down direction relative to the adjusting rod 200.

[0057] It can be understood that, with reference to Figures 3 to 5 , the clamping block 250 is inserted into the adjusting rod 200 along the radial direction of the adjusting rod 200, and both ends of the clamping block 250 protrude from the side wall of the adjusting rod 200. The wall of the insertion slot 320 at the upper end of the sealing rod 300 is provided with two clamping grooves 330 corresponding to the two ends of the clamping block 250, and the two ends of the clamping block 250 are movably inserted into the two clamping grooves 330.

[0058] It can be understood that, in order to enable the sealing rod 300 to move in the up-down direction relative to the adjusting rod 200 and enable the adjusting rod 200 to rotate synchronously with the sealing rod 300, in addition to the structure that the clamping block 250 and the clamping groove 330 cooperate with each other, the cross section of the insertion slot 320 at the upper end of the sealing rod 300 can also be non-circular, such as rectangular, oval, etc., and the cross section shape of the lower end of the adjusting rod 200 is arranged to be suitable for the shape of the insertion slot 320 at the upper end of the sealing rod 300. Thus, the sealing rod 300 can also move in the up-down direction relative to the adjusting rod 200, and the adjusting rod 200 can rotate synchronously with the sealing rod 300.

[0059] With reference to Figures 3 to 5 , in some embodiments, the sealing member 310 is sleeved on the outer periphery of the sealing rod 300, the sealing rod 300 has a second limiting portion 340 abutting against the sealing member 310, and a second elastic member 350 is sleeved on the outer periphery of the sealing rod 300 and the temperature controller 400 below the second limiting portion 340. One end of the second elastic member 350 abuts against the temperature controller 400, and the other end abuts against the sealing member 310. The sealing member 310 is located between the second limiting portion 340 and the second elastic member 350.

[0060] In the above structure, the second elastic member 350 and the second limiting portion 340 can cooperate to clamp the sealing member 310, so that the connection between the sealing member 310 and the sealing rod 300 is more stable. In addition, the second elastic member 350 abuts between the sealing member 310 and the temperature controller 400, and can also press the temperature controller 400, preventing looseness between the temperature controller 400 and the inner wall of the valve body 100.

[0061] It can be understood that the sealing member 310 can be arranged in an integral structure with the sealing rod 300 in addition to being arranged in a split structure with the sealing rod 300, and the present application does not make specific limitations thereto.

[0062] It can be understood that the second elastic member 350 can specifically adopt a compression spring or other elastic structure, and the present application does not make specific limitations thereto.

[0063] With reference to Figures 3 to 5 In some embodiments, the upper end of the valve core 150 is in a non-circular cross section, and the lower end of the valve rod 160 is adapted to the upper end of the valve core 150 and can be sleeved on the upper end of the valve core 150.

[0064] In the above structure, by arranging the upper end of the valve core 150 in a non-circular cross section, the lower end of the valve rod 160 is adapted to the upper end of the valve core 150 and can be sleeved on the upper end of the valve core 150, so that the valve core 150 can be synchronously rotated with the valve rod 160 to open or close the air inlet passage 120.

[0065] It can be understood that in order to enable the valve rod 160 to synchronously rotate the valve core 150 to open or close the air inlet passage 120, in addition to arranging the upper end of the valve core 150 in a non-circular cross section and arranging the lower end of the valve rod 160 to be adapted to the upper end of the valve core 150 and sleeved on the upper end of the valve core 150, a slot body arranged in the up-down direction can also be arranged on the upper end of the valve core 150, and a clamping column capable of being clamped into the slot body on the upper end of the valve core 150 can be arranged on the lower end of the valve rod 160, or a slot body arranged in the up-down direction can be arranged on the lower end of the valve rod 160, and a clamping column capable of being clamped into the slot body on the lower end of the valve rod 160 can be arranged on the upper end of the valve core 150, and the present application does not make specific limitations thereto.

[0066] It can be understood that the valve rod 160 and the valve core 150 can be movably connected, that is, by arranging the above structure, the valve rod 160 can synchronously rotate the valve core 150, and the valve rod 160 can move relative to the valve core 150 in the up-down direction, so that when it is necessary to open or close the air inlet passage 120, the valve rod 160 can be pressed downward so that the lower end of the valve rod 160 is sleeved on the upper end of the valve core 150, thereby synchronously rotating the valve core 150 to open or close the air inlet passage 120, and after the operation is completed, the valve rod 160 is moved upward relative to the valve core 150 to be separated from the valve core 150. This structure can avoid the user or child from opening the air inlet passage 120 during the use of the gas stove, thereby reducing the safety hazards existing in the use of the gas temperature control valve.

[0067] It can be understood that with reference to Figures 3 to 5In some embodiments, the valve stem 160 can drive the valve core 150 to rotate synchronously, and the valve stem 160 can move relative to the valve core 150 in the up-down direction. Specifically, a first elastic member 152 is arranged between the valve stem 160 and the valve core 150, the lower end of the first elastic member 152 abuts against the outer peripheral wall of the valve core 150, and the upper end of the first elastic member 152 abuts against the outer peripheral wall of the valve stem 160. Thus, the connection between the valve stem 160 and the valve core 150 is more stable and compact. When the gas temperature control valve is in use, the valve stem 160 is pressed down to compress the first elastic member 152, so that the lower end of the valve stem 160 is sleeved on the upper end of the valve core 150. Thus, the valve core 150 can be driven to rotate synchronously to open or close the air inlet passage 120. After the operation is completed, the valve stem 160 can be directly released. The first elastic member 152 can automatically reset and push the valve stem 160 to move upward relative to the valve core 150 to disengage from the valve core 150. The structure is simple and convenient for users to operate and use. At the same time, it can avoid the user or child from opening the air inlet passage 120 during the use of the gas stove, thereby reducing the safety hazards of the gas temperature control valve in use. It can be understood that the first elastic member 152 can be sleeved on the outer periphery of the valve stem 160 and the valve core 150. Thus, the installation and fixation of the first elastic member 152 can be facilitated. In addition, the first elastic member 152 can be a compression spring or other elastic structure, which is not limited in the present application.

[0068] With reference to ​ In some embodiments, the upper end of the valve core 150 has two oppositely arranged flat portions, and the lower end of the valve stem 160 is provided with two limiting plates 162 corresponding to the two flat portions. The valve stem 160 can move downward so that the two flat portions of the valve core 150 are located between the two limiting plates 162.

[0069] In the above structure, the upper end of the valve core 150 is provided with two oppositely arranged flat portions, and the lower end of the valve stem 160 is provided with two oppositely arranged limiting plates 162. During use, the valve stem 160 can move downward so that the two flat portions of the valve core 150 are located between the two limiting plates 162. That is, the two limiting plates 162 can cooperate to clamp the upper end of the valve core 150, thereby driving the valve core 150 to rotate synchronously. The arrangement of the limiting plates 162 and the flat portions not only facilitates the valve stem 160 to drive the valve core 150 to rotate synchronously, but also saves materials and reduces the production cost of the gas temperature control valve.

[0070] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present application.
