Description

Technical Field

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

[0004] A manual / electric integrated gas valve with an electric 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; an electric clutch mounted on the valve body, the electric clutch having a central hollow shaft, a rotating wheel, and an electric coupling mechanism, the rotating wheel and the central hollow shaft being coaxially arranged, the central hollow shaft being sleeved on the valve main shaft and rotating together with the valve main shaft, the electric coupling mechanism being used to drive the central hollow shaft and the rotating wheel into a state of rotating together and a state of disengagement, when the central hollow shaft and the rotating wheel are in the state of disengagement, the rotating wheel can freely rotate relative to the central hollow shaft; and a drive motor mounted on the valve body, the output shaft of the drive motor being linked to the rotating wheel through a linkage structure and being able to drive the rotating wheel to rotate through the linkage structure.

[0005] According to an embodiment of the present invention, a manual / electric integrated gas valve with an electric clutch has at least the following beneficial effects: When electric control is required, the electric coupling mechanism of the electric clutch allows the central idler shaft and the rotating wheel to rotate together. The drive motor can drive the rotating wheel to rotate through the linkage structure, thereby driving the central idler shaft and the valve main shaft to rotate, thus achieving control of the gas valve. When switching to manual mode, the electric coupling mechanism of the electric clutch disengages the central idler shaft and the rotating wheel, allowing the rotating wheel to rotate freely and the valve main shaft to rotate independently, thus achieving manual control of the gas valve. The aforementioned gas valve integrates manual and electric control structures. The electric clutch enables function switching. In manual control mode, the rotation of the valve main shaft does not drive the motor shaft of the drive motor to rotate, thus not affecting the angle state of the drive motor or increasing operating damping. A linkage isolation is formed between the drive motor and the valve main shaft, avoiding mutual interference.

[0006] According to some embodiments of this utility model, both the rotating wheel and the linkage structure are gears, the linkage structure is fixed to the output shaft of the drive motor, and the rotating wheel and the linkage structure mesh with each other.

[0007] According to some embodiments of the present invention, the valve body is provided with a shaft position detection device, which is used to detect the rotation angle position of the valve main shaft relative to the valve body.

[0008] According to some embodiments of the present invention, the shaft position detection device includes a detection head and a triggering part. The detection head is fixed at a predetermined position on the valve body, and the triggering part is connected to the valve main shaft and configured to rotate together. The detection head is located on the movement path of the triggering part. When the triggering part moves to the position of the detection head, the detection head can generate an electrical signal.

[0009] According to some embodiments of the present invention, the shaft position detection device is used to detect the rotational limit position of the valve spindle.

[0010] According to some embodiments of the present invention, the valve body is provided with a limit position block, the limit position block stops on the movement path of the trigger part, the end face of the limit position block facing the movement path of the trigger part is provided with a mounting hole, and the detection head passes through the mounting hole and protrudes relative to the limit position block.

[0011] According to some embodiments of this utility model, the electric clutch and the drive motor are mounted on the valve body via a mounting bracket. The mounting bracket includes a motor plate and a clutch bracket. The motor plate is fixed to the end face of the valve body where the valve spindle is located and is perpendicular to the valve spindle. The drive motor is fixed to the motor plate. The clutch bracket is a U-shaped plate with two end portions. Connecting ears extend from opposite sides of the motor plate. The two end portions of the clutch bracket are respectively fixed to the two connecting ears and surround the motor plate to form an accommodating space. The electric clutch is disposed in the accommodating space and fixed to the clutch bracket.

[0012] According to some embodiments of the present invention, a connecting plate extends out from the outer periphery of the electric clutch, and the connecting plate and the clutch frame are fixedly connected.

[0013] According to some embodiments of the present invention, the electric clutch is provided with a boss at one end along the axial direction of the valve main shaft, and the clutch bracket is provided with a positioning hole adapted to the boss, and the boss is inserted into the positioning hole.

[0014] According to some embodiments of the present invention, the electric coupling mechanism includes a linkage member and an electric actuator. The linkage member is movably configured and has a linkage position and a disengagement position. The electric actuator is used to drive the linkage member to change position. When the linkage member is in the linkage position, it links the rotating wheel and the central hollow shaft to make them rotate together. When the linkage member is in the disengagement position, it disengages from at least one of the rotating wheel and the central hollow shaft.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figures 1 to 4A manual / electric integrated gas valve with an electric clutch includes a valve body 100, an electric clutch 200, and a drive motor 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 electric clutch 200 is mounted on the valve body 110 and includes a central hollow shaft 210, a rotating wheel 220, and an electric coupling mechanism. The rotating wheel 220 and the central hollow shaft 210 are coaxially arranged. The central hollow shaft 210 is sleeved on the valve spindle 120 and rotates together with it. The electric coupling mechanism drives the central hollow shaft 210 and the rotating wheel 220 into a state of rotating together and a state of disengagement. When the central hollow shaft 210 and the rotating wheel 220 are in the disengaged state, the rotating wheel 220 can freely rotate relative to the central hollow shaft 210. The drive motor 300 is mounted on the valve body 110. The output shaft of the drive motor 300 is linked to the rotating wheel 220 through the linkage structure 400 and can drive the rotating wheel 220 to rotate through the linkage structure 400.

[0034] When electric control is required, the electric coupling mechanism of the electric clutch 200 allows the central idle shaft 210 and the rotating wheel 220 to rotate together. The drive motor 300, through the linkage structure 400, drives the rotating wheel 220 to rotate, thereby driving the central idle shaft 210 and the valve main shaft 120 to rotate, thus controlling the gas valve. When switching to manual mode, the electric coupling mechanism of the electric clutch 200 disengages the central idle shaft 210 and the rotating wheel 220, allowing the rotating wheel 220 to rotate freely and the valve main shaft 120 to rotate independently, thus enabling manual control of the gas valve. The aforementioned gas valve integrates manual and electric control structures. The electric clutch 200 enables function switching. In manual control mode, the rotation of the valve main shaft 120 does not drive the motor shaft of the drive motor 300, thus not affecting the angle of the drive motor 300 or increasing operating damping. A linkage isolation is formed between the drive motor 300 and the valve main shaft 120, avoiding mutual interference.

[0035] In this embodiment, both the rotating wheel 220 and the linkage structure 400 are gears. The linkage structure 400 is fixed to the output shaft of the drive motor 300, and the rotating wheel 220 and the linkage structure 400 mesh with each other. With the above structure, the gear transmission structure is stable.

[0036] It is conceivable that in other embodiments, the rotating wheel 220 is not limited to using gears; for example, it could be a synchronous pulley. The linkage structure 400 could include another synchronous pulley and a synchronous belt, linking the rotating wheel 220 and the output shaft of the drive motor 300 via synchronous belt drive. It is understood that there are many implementations of the mechanism for achieving linkage between the wheel and the shaft in the art, and those skilled in the art can configure it according to the actual situation.

[0037] In this embodiment, the valve body 110 is equipped with a shaft position detection device 500, 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.

[0038] 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.

[0039] 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 300 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 300 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 300 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 300 and the valve main shaft 120. This avoids excessive errors accumulated from repeated rotations that could affect the electric control.

[0040] In this embodiment, the valve body 110 is provided with a limit position block 111, which stops on the movement path of the trigger part 520. A mounting hole is provided on the end face of the limit position block 111 facing the movement path of the trigger part 520. The detection head 510 passes through the mounting hole and protrudes relative to the limit position block 111. 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.

[0041] 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.

[0042] In this embodiment, the electric clutch 200 and the drive motor 300 are mounted on the valve body 110 via a mounting bracket 600. The mounting bracket 600 includes a motor plate 610 and a clutch bracket 620. The motor plate 610 is fixed to the valve body 110 and has an end face of the valve spindle 120 perpendicular to the valve spindle 120. The drive motor 300 is fixed to the motor plate 610. The clutch bracket 620 is a U-shaped plate with two end portions 621. Connecting ears 611 extend from opposite sides of the motor plate 610. The two end portions 621 of the clutch bracket 620 are respectively fixed to the two connecting ears 611 and enclose the motor plate 610 to form an accommodating space. The electric clutch 200 is disposed in the accommodating space and fixed to the clutch bracket 620. The above-described structure for fixing the electric clutch 200 and the drive motor 300 is simple, firmly fixed, and has a compact overall structure.

[0043] In this embodiment, a connecting plate 230 extends from the outer periphery of the electric clutch 200, and the connecting plate 230 is fixedly connected to the clutch bracket 620. Using the above structure to fix the electric clutch 200 to the mounting bracket 600, the installation structure is simple. In this embodiment, the connecting plate 230 and the clutch bracket 620 can be connected to each other by screws or rivets.

[0044] In this embodiment, the electric clutch 200 has a boss 240 at one end along the axial direction of the valve main shaft 120, and the clutch bracket 620 has a positioning hole 622 that matches the boss 240, with the boss 240 inserted into the positioning hole 622. With this structure, the electric clutch 200 can be positioned and installed more stably and accurately.

[0045] In this embodiment, the valve body 110 has a valve spindle 120, one end of which is provided with a mounting post 130. The motor plate 610 has a sleeve hole 612, which is adapted to and sleeved on the mounting post 130. The circumferential surface of the mounting post 130 has an axially formed groove 131. One end of the groove 131 extends through the mounting post 130 and forms an insertion opening. The other end of the groove 131 has an abutment limiting part. A locking block 613 extends inward from the wall of the sleeve hole 612. The locking block 613 is adapted to and inserted into the groove 131. The mounting post 130 has an external thread and is threadedly connected to a nut 700. The nut 700 and the abutment limiting part at the other end of the groove 131 clamp and fix the motor plate 610. The above structure is used to fix the motor plate 610, which is simple and firmly fixed. In this embodiment, two sets of card blocks 613 and card slots 131 are provided and distributed at a 180-degree angle along the circumference of the mounting post 130, resulting in a symmetrical mounting structure and stable installation.

[0046] In this embodiment, the two end portions 621 of the clutch frame 620 are 90-degree bends. The two end portions 621 of the clutch frame 620 and the two connecting ears 611 extending from opposite sides of the motor plate 610 overlap and are locked together by threaded fasteners. In this embodiment, the aforementioned threaded fasteners are screws, or a combination of bolts and nuts may also be used. The above-described structure for fixing the clutch frame 620 and the motor plate 610 is simple and easy to implement.

[0047] In an embodiment, the electric coupling mechanism includes a linkage member and an electric actuator. The linkage member is movably configured and has a linkage position and a disengagement position. The electric actuator is used to drive the linkage member to change position. When the linkage member is in the linkage position, it links the rotating wheel 220 and the central hollow shaft 210 to make them rotate together. When the linkage member is in the disengagement position, the linkage member disengages from at least one of the rotating wheel 220 and the central hollow shaft 210.

[0048] In some embodiments, the linkage can be a friction disc, which is connected to and rotates together with the rotating wheel 220. The friction disc can move axially relative to the rotating wheel 220. A mating disc is coaxially fixed to the central hollow shaft 210. An electric actuator is used to drive the friction disc to move axially. When it is necessary to link the rotating wheel 220 and the central hollow shaft 210, the electric actuator drives the friction disc to press against the mating disc, so that the friction disc is in the linked position. The friction force causes the mating disc and the friction disc to rotate together, thereby achieving synchronous rotation of the rotating wheel 220 and the central hollow shaft 210. When it is necessary to disengage the rotating wheel 220 and the central hollow shaft 210, the electric actuator resets the friction disc, so that the friction disc returns to the disengaged position. The electric actuator can specifically be an electromagnet, an electric push rod, etc.

[0049] It is conceivable that the linkage is not limited to the structure described above. In other embodiments, the rotating wheel 220 can be movably sleeved on the outer periphery of the central hollow shaft 210 so that it can rotate relative to the rotating wheel 220 or the central hollow shaft 210. The inner circumferential surface of the rotating wheel 220 or the outer circumferential surface of the central hollow shaft 210 is circular by default. The positioning pin can be telescopically set and can press against the end face of the default part of the inner circumferential surface of the rotating wheel 220 or the outer circumferential surface of the central hollow shaft 210, so that the rotating wheel 220 and the central hollow shaft 210 are mutually engaged and can rotate together, thereby realizing the function of the corresponding electric coupling mechanism.

[0050] It is conceivable that the electric clutch 200 can also adopt other existing structures, and the specific choice can be made according to the actual situation.

[0051] 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.

[0052] 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.
