Description

Technical Field

[0001] This application relates to the field of valves, and in particular to a manual / electric switching device for a direct-drive valve electric actuator. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the conveyed medium. Based on their function, they can be classified as shut-off valves, check valves, regulating valves, etc. Direct-connected valves, sometimes also called direct-mount valves or compact valves, refer to a class of valves designed for direct connection to actuators (such as electric or pneumatic actuators) without the need for additional supports or connections.

[0003] Existing direct-drive valve electric actuators mainly use electromagnets to control the manual / electric switching. When the power is off, if the valve is in electric operation mode, it is difficult to manually switch to manual operation mode, which is inconvenient to use. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, this application provides a manual / electric switching device for a direct-drive valve electric actuator.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0006] A direct-drive valve electric actuator manual / electric switching device includes a valve assembly, an actuation component at the top of the valve assembly, a clutch component inside the actuation component, a valve stem, a synchronizing block fixedly mounted on the top of the valve stem, a synchronizing groove on the outer side of the synchronizing block, a gear cavity in the actuation component, a clutch disc with synchronizing teeth in the middle of the clutch disc, the synchronizing teeth being slidably connected to the synchronizing groove, a clutch frame rotatably connected to the outside of the clutch disc, electromagnets at both ends of the clutch disc being fixedly connected to the inside of the gear cavity, magnetic blocks fixedly mounted at the bottom of both ends of the clutch frame, and a return spring fixedly mounted between the magnetic blocks and the electromagnets.

[0007] By adopting the above scheme, the setting of the actuator facilitates the control of the opening and closing of the valve assembly. The setting of the clutch assembly facilitates the switching between manual and electric operation of the actuator. A synchronizing block is fixedly installed on the top of the valve stem, so that the rotation of the synchronizing block drives the rotation of the valve stem, thereby controlling the opening and closing of the valve assembly. The synchronizing teeth are slidably connected to the synchronizing groove, so that the rotation of the clutch disc drives the rotation of the valve stem. The clutch disc can also slide up and down along the synchronizing groove, facilitating the switching between manual and electric operation. A clutch frame is rotatably connected to the outside of the clutch disc, so that the up and down movement of the clutch frame drives the up and down movement of the clutch disc without obstructing the rotation of the clutch disc. Magnetic blocks are fixedly installed at the bottom of both ends of the clutch frame, so that the electromagnet can attract the magnetic blocks, thereby controlling the downward sliding of the clutch disc. A return spring is fixedly installed between the magnetic blocks and the electromagnet, so that when the electromagnet is de-energized, the return spring provides elastic force to move the clutch frame and the clutch disc upward, thereby switching the device to manual operation.

[0008] Furthermore, a guide rod is fixedly installed at the center of the top of the electromagnet, and a guide hole is opened in the center of the magnetic block. The guide rod is slidably connected to the guide hole.

[0010] Furthermore, a limiting block is fixedly installed on the top of the guide rod, and the limiting block is located at the top of the guide hole.

[0011] By adopting the above scheme and setting the limit block, it is easy to limit the up and down sliding of the clutch frame.

[0012] Furthermore, the clutch disc is provided with clutch teeth at both the top and bottom, a handwheel is rotatably connected to the top of the gear cavity, and a second clutch groove is provided at the bottom of the handwheel.

[0013] By adopting the above scheme, a second clutch groove is provided at the bottom of the handwheel, which facilitates the engagement of the clutch teeth with the second clutch groove when the clutch disc slides upward, thereby making it convenient to rotate the handwheel to control the rotation of the clutch disc.

[0014] Furthermore, a first bevel tooth is rotatably connected inside the gear cavity. The first bevel tooth is located at the bottom of the clutch disc, and a first clutch groove is formed at the top of the first bevel tooth.

[0015] By adopting the above scheme, a first clutch groove is provided at the top of the first bevel tooth, which facilitates the engagement of the clutch tooth with the first clutch groove when the clutch disc slides downward, thereby controlling the rotation of the clutch disc by the rotation of the first bevel tooth.

[0016] Furthermore, a motor is fixedly installed on one side of the gear cavity, and a second bevel tooth is fixedly installed on the output end of the motor, the second bevel tooth meshing with the first bevel tooth.

[0017] By adopting the above scheme, the second bevel tooth meshes with the first bevel tooth, which facilitates the operation of the motor so that the second bevel tooth drives the first bevel tooth to rotate.

[0018] Furthermore, a valve core is fixedly installed at the bottom of the valve stem, and a valve body is sleeved on the outside of the valve core, with the valve core and valve body rotatably connected.

[0019] By adopting the above scheme, the valve core is rotatably connected to the valve body, which facilitates the rotation of the valve stem to drive the valve core to rotate, thereby controlling the opening and closing of the valve assembly.

[0020] Furthermore, connecting flanges are fixedly installed at both ends of the valve body, and the valve body is fixedly connected to the bottom of the gear cavity.

[0021] By adopting the above scheme and setting the connecting flange, it is easy to connect the device to the external pipeline, thereby facilitating the device to control the on / off state of the external pipeline.

[0022] In summary, this application has the following technical effects:

[0023] By configuring the actuator components, the opening and closing of the valve assembly can be easily controlled. The clutch assembly facilitates switching between manual and electric operation of the actuator components. A synchronizing block is fixedly installed on the top of the valve stem, allowing the rotation of the synchronizing block to drive the valve stem rotation, thereby controlling the opening and closing of the valve assembly. A slidable connection between the synchronizing teeth and the synchronizing groove allows the rotation of the clutch disc to drive the valve stem rotation, and the clutch disc can slide up and down along the synchronizing groove, facilitating manual / electric switching. A clutch frame is rotatably connected to the outside of the clutch disc, allowing the clutch frame to move up and down, driving the clutch disc to slide up and down without obstructing the clutch disc's rotation. Magnetic blocks are fixedly installed at the bottom of both ends of the clutch frame, allowing the electromagnet to attract the magnetic blocks, thus controlling the downward sliding of the clutch disc. A return spring is fixedly installed between the magnetic blocks and the electromagnet, allowing the return spring to provide elasticity when the electromagnet is de-energized, causing the clutch frame to drive the clutch disc upward, thus switching the device to manual operation. This utility model achieves the effect of automatically switching to manual operation mode when the device is powered off, and has high practical value. Attached Figure Description
