Description

Technical Field

[0001] This utility model relates to gas appliances, and in particular to a manual-electric integrated gas valve with a mechanical clutch. Background Technology

[0002] Existing manual gas valves primarily control the gas valve by manually turning the valve spindle. Other gas valves use a motor to drive the valve spindle for electric control. However, in some situations, users need more flexible operating options, and the aforementioned gas valves, which can only be used manually or electrically in isolation, do not meet these requirements. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a manual-electric integrated gas valve with a mechanical clutch.

[0004] A manual / electric integrated gas valve with a mechanical clutch according to an embodiment of the present invention includes: a valve body, comprising a valve body and a valve main shaft, the valve main shaft being rotatably mounted on the valve body; a drive motor, mounted on the valve body; a mechanical clutch, comprising a drive wheel, a linkage mechanism, a transmission wheel, and an elastic element, the drive wheel being rotatably sleeved on the valve main shaft, the transmission wheel being movably sleeved on the valve main shaft, the transmission wheel and the valve main shaft being configured to rotate together and the transmission wheel being axially movable relative to the valve main shaft, the elastic element cooperating with the transmission wheel and used to apply an axial pressing force to the transmission wheel against the drive wheel, the transmission wheel and the drive wheel cooperating with each other through a torque transmission structure, defined such that the transmission wheel and the drive wheel... The force that drives the drive wheels to rotate relative to each other is a torsional force. The torque transmission structure is used to enable the transmission wheel and the drive wheel to rotate together within a predetermined torsional force range, while the transmission wheel and the drive wheel can rotate relative to each other when the predetermined torsional force is exceeded. The linkage mechanism has a one-way self-locking property, and the output shaft of the drive motor is linked to the drive wheel in one direction through the linkage mechanism. When the valve main shaft and the transmission wheel are manually driven to rotate together, the linkage mechanism restricts the rotation of the drive wheel, and the transmission wheel can rotate relative to the drive wheel. When the drive motor drives the drive wheel to rotate through the linkage mechanism, the drive wheel can drive the transmission wheel and the valve main shaft to rotate together through the torque transmission structure.

[0005] According to an embodiment of this utility model, a manual-electric integrated gas valve with a mechanical clutch has at least the following advantages: When manually controlling the gas valve, the valve main shaft is directly rotated. Since the drive wheel is locked by the linkage mechanism, and the torque transmission structure ensures that the rotation of the transmission wheel relative to the drive wheel is not affected even when a certain force is exceeded, manual operation can be achieved by rotating the valve main shaft. When electrically controlling the gas valve, the drive motor drives the drive wheel to rotate through the linkage mechanism. The drive wheel, through the torque transmission structure, drives the transmission wheel to rotate, which in turn drives the valve main shaft to rotate, thus achieving electric control. The aforementioned manual-electric integrated gas valve integrates manual and electric control structures. By setting a mechanical clutch, manual and electric drives do not interfere with each other. Furthermore, the mechanical clutch structure allows for switching between manual and electric operation without any additional operation or control, making operation and control convenient.

[0006] According to some embodiments of the present invention, the torque transmission structure includes a convex portion and a groove portion. The convex portion and the groove portion are correspondingly disposed on the end faces of the transmission wheel and the drive wheel that cooperate with each other. Multiple sets of the convex portion and the groove portion are disposed and arranged circumferentially along the valve main shaft. The convex portion is adapted to be inserted into the groove portion and can slide out of the groove portion under the action of a predetermined external force.

[0007] According to some embodiments of the present invention, the convex portion is a spherical crown, and the groove portion is adapted to the shape of the spherical crown.

[0008] According to some embodiments of this utility model, the linkage mechanism is a worm gear mechanism.

[0009] According to some embodiments of this utility model, the linkage mechanism includes a main worm and a worm gear assembly. The main worm is coaxially arranged with the output shaft of the drive motor and can rotate together. The worm gear assembly is pivotally arranged and perpendicular to the main worm. The worm gear assembly is provided with a worm wheel portion and a worm portion. The worm wheel portion and the worm portion are coaxially arranged and mesh with the main worm. The drive wheel is a worm wheel and meshes with the worm portion.

[0010] According to some embodiments of the present invention, the valve body is connected to a mounting housing, and the mechanical clutch is housed within the mounting housing.

[0011] According to some embodiments of this utility model, the mounting housing includes a motor plate and a clutch cover. The motor plate is fixed to the valve body. The drive wheel, the linkage mechanism, the transmission wheel, and the elastic element are disposed on one side of the motor plate. The clutch cover covers the outside of the drive wheel, the linkage mechanism, the transmission wheel, and the elastic element and is fixed to the motor plate. The clutch cover and the motor plate together form the cavity of the mounting housing. The drive motor is fixed to the other side of the motor plate.

[0012] According to some embodiments of the present invention, the mounting housing is provided with a through hole for the valve spindle to pass through. The valve spindle passes through the through hole and exits the mounting housing. A baffle is movably sleeved on the valve spindle. The baffle is configured to rotate together with the valve spindle. The baffle abuts against the periphery of the hole on the side of the through hole near the inside of the mounting housing. An elastic member is disposed between the baffle and the transmission wheel. The two ends of the elastic member abut against the baffle and the transmission wheel, respectively.

[0013] According to some embodiments of the present invention, a shaft position detection device is also included, which is used to detect the rotation angle position of the valve main shaft relative to the valve body.

[0035] Reference Figures 1 to 7 A manual / electric integrated gas valve with a mechanical clutch includes: a valve body 100, a drive motor 200, and a mechanical clutch 300. The valve body 100 includes a valve body 110 and a valve spindle 120, with the valve spindle 120 rotatably mounted on the valve body 110. The drive motor 200 is mounted on the valve body 110. The mechanical clutch 300 includes a drive wheel 310, a linkage mechanism 320, a transmission wheel 330, and an elastic element 340. The drive wheel 310 is rotatably sleeved on the valve spindle 120, and the transmission wheel 330 is movably sleeved on the valve spindle 120. The transmission wheel 330 and the valve spindle 120 are configured to rotate together, and the transmission wheel 330 can move axially relative to the valve spindle 120. The elastic element 340 cooperates with the transmission wheel 330 and applies an axial pressing force to the transmission wheel 330 against the drive wheel 310. The transmission wheel 330 and the drive wheel 310 cooperate with each other through a torque transmission structure. The force that causes the transmission wheel 330 and the drive wheel 310 to rotate relative to each other is defined as a torsional force. The torque transmission structure is used to enable the transmission wheel 330 and the drive wheel 310 to rotate together within a predetermined torsional force range, while the transmission wheel 330 and the drive wheel 310 can rotate relative to each other when the predetermined torsional force is exceeded. The linkage mechanism 320 has a one-way self-locking property, and the output shaft of the drive motor 200 is linked to the drive wheel 310 in one direction through the linkage mechanism 320. Specifically, when the valve main shaft 120 and the transmission wheel 330 rotate together manually, the linkage mechanism 320 restricts the rotation of the drive wheel 310, and the transmission wheel 330 can rotate relative to the drive wheel 310. When the drive motor 200 drives the drive wheel 310 to rotate through the linkage mechanism 320, the drive wheel 310 can drive the transmission wheel 330 and the valve main shaft 120 to rotate together through the torque transmission structure.

[0036] When manually controlling the gas valve, the valve main shaft 120 is directly rotated. Since the drive wheel 310 is locked by the linkage mechanism 320, and the torque transmission structure ensures that the rotation of the transmission wheel 330 relative to the drive wheel 310 is not affected even when a certain force is applied, the valve main shaft 120 can be rotated to achieve manual operation. When electrically controlling the gas valve, the drive motor 200 drives the drive wheel 310 to rotate via the linkage mechanism 320. The drive wheel 310, through the torque transmission structure, drives the transmission wheel 330 to rotate, which in turn drives the valve main shaft 120 to rotate, thus achieving electric control. The aforementioned integrated manual and electric gas valve combines manual and electric control structures. By incorporating a mechanical clutch 300, manual and electric drives do not interfere with each other. Furthermore, the structure of the mechanical clutch 300 allows for seamless switching between manual and electric operation without any additional operation or control, making operation and control convenient.

[0037] In addition, since the drive wheel 310 and the transmission wheel 330 are linked by a torque transmission structure, the torque transmission structure will not transmit power when the drive motor 200 drives the valve main shaft 120 to rotate to the limit position, thus forming torque protection and providing better protection for the gas valve.

[0038] In this embodiment, the valve spindle 120 has a cylindrical section and a non-circular section. The drive wheel 310 pivots on the cylindrical section, allowing the two to rotate relative to each other. The transmission wheel 330 has a sliding connection hole adapted to the non-circular section and is movably sleeved on the non-circular section, allowing it to move axially relative to the valve spindle 120 while also rotating together with the valve spindle 120.

[0039] In this embodiment, the torque transmission structure includes a convex portion 351 and a recessed portion 352. The convex portion 351 and the recessed portion 352 are correspondingly disposed on the end faces of the transmission wheel 330 and the drive wheel 310 that cooperate with each other. Multiple sets of convex portions 351 and recessed portions 352 are arranged circumferentially along the valve main shaft 120. The convex portion 351 is adapted to be inserted into the recessed portion 352 and can slide out of the recessed portion 352 under a predetermined external force. With the above structure, the cooperation of the convex portion 351 and the recessed portion 352 can transmit a certain range of torque, ensuring that transmission can be realized; when the external force exceeds the corresponding force, the convex portion 351 can continuously slide out of the recessed portion 352 and enter the adjacent recessed portion 352, thereby allowing the transmission wheel 330 to rotate relative to the drive wheel 310.

[0040] In this embodiment, the convex portion 351 is a spherical crown, and the recessed portion 352 is adapted to the shape of the spherical crown. With the above structure, the fit between the convex portion 351 and the recessed portion 352 is smoother.

[0041] It is conceivable that the torque transmission structure is not limited to the structure described above. For example, a friction plate structure can be used, so that the transmission wheel 330 and the drive wheel 310 rub against each other through the friction plate to achieve torque transmission and the function of relative sliding under the action of external force exceeding the predetermined force.

[0042] In this embodiment, the linkage mechanism 320 is a worm gear mechanism. The linkage mechanism 320, employing a worm gear mechanism, can achieve unidirectional transmission and self-locking, and its structure is simple and easy to implement.

[0043] In this embodiment, the linkage mechanism 320 includes a main worm gear 321 and a worm wheel and worm gear assembly 322. The main worm gear 321 is coaxially arranged with the output shaft of the drive motor 200 and can rotate together. The worm wheel and worm gear assembly 322 is pivotally arranged and perpendicular to the main worm gear 321. The worm wheel and worm gear assembly 322 is provided with a worm wheel portion 3221 and a worm portion 3222. The worm wheel portion 3221 and the worm portion 3222 are coaxially arranged, and the worm wheel portion 3221 meshes with the main worm gear 321. The drive wheel 310 is a worm wheel and meshes with the worm portion 3222. With the above structure, a two-stage worm wheel and worm gear transmission can be formed, which has better self-locking performance and a large transmission ratio, which is beneficial to reducing the size of the motor.

[0044] It is conceivable that the linkage mechanism 320 is not limited to using a worm gear mechanism. For example, it can use a screw drive or other linkage mechanisms 320 with one-way self-locking. The specific configuration can be made according to the actual situation.

[0045] In this embodiment, the valve body 110 is connected to a mounting housing 400, and the mechanical clutch 300 is housed within the mounting housing 400, thereby providing better protection for the mechanical clutch 300.

[0046] In this embodiment, the mounting housing 400 includes a motor plate 410 and a clutch cover 420. The motor plate 410 is fixed to the valve body 110. The drive wheel 310, the linkage mechanism 320, the transmission wheel 330, and the elastic element 340 are disposed on one side of the motor plate 410. The clutch cover 420 covers the outside of the drive wheel 310, the linkage mechanism 320, the transmission wheel 330, and the elastic element 340 and is fixed to the motor plate 410. The clutch cover 420 and the motor plate 410 together form the cavity of the mounting housing 400. The drive motor 200 is fixed to the other side of the motor plate 410. With the above structure, the mounting housing 400 is easy to assemble, and the overall structure of the gas valve is compact.

[0047] In this embodiment, the mounting housing 400 is provided with a through hole 430 for the valve spindle 120 to pass through. The valve spindle 120 passes through the through hole 430 and exits the mounting housing 400. A baffle 130 is movably sleeved on the valve spindle 120. The baffle 130 is configured to rotate together with the valve spindle 120. The baffle 130 abuts against the periphery of the through hole 430 on the side closest to the interior of the mounting housing 400. An elastic element 340 is disposed between the baffle 130 and the transmission wheel 330, with both ends of the elastic element 340 abutting against the baffle 130 and the transmission wheel 330, respectively. With the above structure, the installation position of the elastic element 340 is stable, and the baffle 130 and the mounting housing 400 serve as supports for one end of the elastic element 340, making installation convenient.

[0048] In this embodiment, the elastic element 340 is a spring. Of course, in some embodiments, the elastic element 340 may also be an elastic body with other structures, such as a sheet, a rubber body, etc.

[0049] In one embodiment, the section on the valve spindle 120 that mates with the baffle 130 can be set to be non-circular, and the baffle 130 and the section can be adapted to each other so that they can rotate with the valve spindle 120.

[0050] In this embodiment, the valve body 110 has a valve spindle 120, one end of which is provided with a mounting post 111. The motor plate 410 has a sleeve hole 411, which is adapted to and sleeved on the mounting post 111. The circumferential surface of the mounting post 111 has an axially formed groove 112. One end of the groove 112 extends through the mounting post 111 and forms an insertion opening. The other end of the groove 112 has an abutment limiting part. A locking block 412 extends inward from the wall of the sleeve hole 411. The locking block 412 is adapted to and inserted into the groove 112. The mounting post 111 has an external thread and is threadedly connected to a nut 450. The nut 450 and the abutment limiting part at the other end of the groove 112 clamp and fix the motor plate 410. The above structure is used to fix the motor plate 410, which is simple and firmly fixed. In this embodiment, two sets of card blocks 412 and card slots 112 are provided and distributed at a 180-degree angle along the circumference of the mounting post 111.

[0051] In this embodiment, the motor plate 410 is bent to form two mounting plates 413, which are arranged opposite each other at a distance. The two ends of the worm gear 322 of the linkage mechanism 320 are pivotally connected to the two mounting plates 413 respectively. By using the mounting plates 413 formed by bending the motor plate 410 to connect the worm gear 322, the structure is compact and easy to install.

[0052] In this embodiment, a washer 440 is provided between the clutch cover 420 and the motor plate 410, and the clutch cover 420 and the motor plate 410 are fastened together by screws.

[0053] In this embodiment, a shaft position detection device 500 is also included, which is used to detect the rotational angle position of the valve main shaft 120 relative to the valve body 110. Using the above structure, the angular position of the valve main shaft 120 can be detected, thereby facilitating subsequent feedback of angle information for intelligent control.

[0054] In this embodiment, the shaft position detection device 500 includes a detection head 510 and a trigger part 520. The detection head 510 is fixed at a predetermined position on the valve body 110, and the trigger part 520 is connected to the valve main shaft 120 and configured to rotate together. The detection head 510 is located on the movement path of the trigger part 520. When the trigger part 520 moves to the position of the detection head 510, the detection head 510 generates an electrical signal. The shaft position detection device 500 described above has a simple structure and is easy to implement.

[0055] In this embodiment, the shaft position detection device 500 is used to detect the rotational limit position of the valve main shaft 120. When using the manual / electric integrated gas valve, the drive motor 200 and the shaft position detection device 500 are electrically connected to the controller. When the shaft position detection device 500 detects that the valve main shaft 120 has rotated to its limit position, the controller controls the drive motor 200 to stop, thereby preventing excessive rotation of the valve main shaft 120 and providing better protection for the components. In addition, when the shaft position detection device 500 detects that the valve main shaft 120 has rotated to its limit position, the controller can set the current angular position of the output shaft of the drive motor 200 and the valve main shaft 120 as the position origin of the control program to recalibrate the positions of the output shaft of the drive motor 200 and the valve main shaft 120. This avoids excessive errors accumulated from repeated rotations that could affect the electric control.

[0056] In this embodiment, the valve body 110 is provided with a limit position block 113, which stops on the movement path of the trigger part 520. The end face of the limit position block 113 facing the movement path of the trigger part 520 has a mounting hole, and the detection head 510 passes through the mounting hole and protrudes relative to the limit position block 113. With the above structure, the installation structure of the detection head 510 is simple, and it can realize the detection of the rotational limit position of the valve spindle 120.

[0057] In this embodiment, the detection head 510 can be a conductive connector, and the trigger part 520 on the valve spindle 120 can be a conductive element. The conductive connector and the trigger part 520 can be connected to a detection circuit. When the detection head 510 and the trigger part 520 come into contact, a circuit loop is formed through the valve body 110, thereby generating a current. This current can be used as a control signal to achieve detection. Of course, in other embodiments, the detection head 510 is not limited to the above-described structure. For example, it can also be a Hall sensor, a photoelectric sensor, etc. The specific configuration can be adjusted according to the actual situation, and the trigger part 520 can be adapted to the type of sensor used. In this embodiment, the controller can be a PLC or a microcontroller circuit, which can be configured according to the actual situation.

[0058] In this embodiment, a motor angle detection device 600 is also included, which is used to detect the rotation angle of the output shaft of the drive motor 200. By setting the motor angle detection device 600, the angle of the output shaft of the drive motor 200 can be detected, facilitating subsequent automated intelligent control. In this embodiment, the motor angle detection device 600 can also be used to detect the number of rotations of the output shaft of the drive motor 200, thereby providing information on the control stroke.

[0059] In this embodiment, the motor angle detection device 600 includes a matching detection sensor 610 and a detection unit 620. The detection unit 620 can trigger the detection sensor 610. The detection unit 620 is fixed to one end of the main worm gear 321 and offset from the axis of the main worm gear 321. The detection sensor 610 is fixed to the clutch cover 420 and faces one end of the main worm gear 321. Since the main worm gear 321 and the output shaft of the drive motor 200 are coaxially arranged, and the detection unit 620 is located offset from the axis of the main worm gear 321, the angular position of the output shaft of the drive motor 200 can be detected by checking whether there is a signal change in the sensor 610 to determine whether the detection unit 620 is facing the detection sensor 610. In addition, the number of times the sensing signal of the detection sensor 610 appears can also be detected by checking the number of rotations of the output shaft of the drive motor 200, which is convenient for subsequent stroke calculation. In this embodiment, the detection sensor 610 can be a Hall sensor, and the detection unit 620 can be a magnet or other structure that can be matched with the Hall sensor. It is conceivable that the motor angle detection device 600 is not limited to the structure described above; for example, it can be detected using an encoder or other similar structures.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model 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 spirit of the present utility model.
