Technical Field

[0001] The utility model belongs to the technical field of intelligent integrated electric stop valves, and in particular relates to an intelligent integrated electric stop valve. Background Art

[0002] The intelligent integrated electric stop valve consists of an electric actuator and a stop valve. It is a commonly used automation control device in factories.

[0003] The existing intelligent integrated electric stop valve is installed in the working position and issues instructions to the electric actuator through the power signal to adjust the working state of the stop valve. However, it has the following defects: (1) When the existing intelligent integrated electric stop valve is in use, in order to ensure that the stop valve can still adjust the working state of the valve body in time when the electric actuator has a power failure or other faults, a manual adjustment device is set on the valve body to realize manual adjustment. However, in actual operation, the handwheel of the manual adjustment device is prone to misoperation and changes the working state of the valve body. For this reason, we propose an intelligent integrated electric stop valve. Utility Model Content

[0004] The purpose of the utility model is to provide an intelligent integrated electric stop valve to solve the problem of misoperation of the intelligent integrated electric stop valve proposed in the background art and change of the working state of the valve body.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: an intelligent integrated electric stop valve, comprising a valve body, an electric control assembly being provided on the top of the valve body, a manual valve stem being provided on one side of the electric control assembly, a sleeve being fixed to the end of the manual valve stem, a movable block being provided inside the sleeve, a synchronization rod being fixed to one end of the movable block, a synchronization groove being provided on the inner end surface of the sleeve, and a handwheel being fixed to the other end of the movable block.

[0006] Preferably, a top spring is sleeved on the outer wall of the synchronization rod, and the top spring is located inside the sleeve.

[0007] Preferably, the longitudinal section of the synchronization rod is a circular structure, and the end surface of the synchronization rod is configured as an arc surface.

[0008] Preferably, a side groove with a circular cross-section is opened on the side wall of the movable block, a side block is arranged inside the side groove, and the side block is fixed on the inner wall of the sleeve.

[0009] Preferably, a spherical groove is formed on the surface of the side block, and a ball is embedded in the spherical groove.

[0010] Preferably, the longitudinal section of the movable block is a circular structure, and the cross section of the movable block is an I-shaped structure.

[0011] Preferably, the longitudinal section of the sleeve is a circular structure, and the central axes of the sleeve and the movable block coincide with each other.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) Through the designed movable block, sleeve, synchronization rod and synchronization groove, the handwheel and the manual valve stem are connected by the movable block and sleeve for rotation, ensuring that the handwheel will not cause the manual valve stem to rotate and adjust when it is accidentally touched, thereby changing the working state of the valve body, thereby improving the reliability of the utility model. When manual operation is required, it is only necessary to press the handwheel to make the movable block slide in the sleeve, insert the synchronization rod into the synchronization groove, and connect the sleeve and the movable block together to make them rotate synchronously, and then drive the manual valve stem to rotate and adjust through the handwheel. Through the designed top spring, the top spring exerts an elastic force on the movable block, so that the movable block slides toward the outer end of the sleeve when there is no external force squeezing, so that the synchronization rod automatically separates from the synchronization groove. Through the designed side blocks and side grooves, the movable block is limited to prevent the movable block from falling off from the sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

Through the designed movable block 4, sleeve 6, synchronization rod 10 and synchronization groove 9, the hand wheel 5 and the manual valve stem 3 are rotatably connected by the movable block 4 and the sleeve 6, ensuring that the hand wheel 5 will not cause the manual valve stem 3 to rotate and adjust when it is accidentally touched, thereby changing the working state of the valve body 1, thereby improving the reliability of the utility model. When manual operation is required, it is only necessary to press the hand wheel 5 to make the movable block 4 slide in the sleeve 6, and insert the synchronization rod 10 into the synchronization groove 9 to connect the sleeve 6 and the movable block 4 together so that they rotate synchronously, and then drive the manual valve stem 3 to rotate and adjust through the hand wheel 5. The outer wall of the synchronization rod 10 is provided with a top spring 7. Through the designed top spring 7, the top spring 7 exerts an elastic pushing effect on the movable block 4, so that the movable block 4 slides toward the outer end of the sleeve 6 when there is no external force squeezing, so that the synchronization rod 10 is automatically separated from the synchronization groove 9, and the top spring 7 is inside the sleeve 6. The longitudinal section of the synchronization rod 10 is a circular structure, and the end face of the synchronization rod 10 is set to a circular arc surface 8. Through the designed circular arc surface 8, the end face of the synchronization rod 10 is lubricated, making it easier to insert into the synchronization groove 9.

[0022] In this embodiment, preferably, the side wall of the movable block 4 is provided with a side groove 11 with a circular cross-section, and a side block 13 is arranged inside the side groove 11. The designed side block 13 and side groove 11 limit the movable block 4 to prevent the movable block 4 from falling off from the sleeve 6, and the side block 13 is fixed on the inner wall of the sleeve 6. A spherical groove is provided on the surface of the side block 13, and a ball 12 is embedded in the spherical groove. The designed ball 12 plays a lubricating role to reduce the wear of the surface of the side block 13 and the side groove 11. The longitudinal section of the movable block 4 is a circular structure, the cross-section of the movable block 4 is an I-shaped structure, the longitudinal section of the sleeve 6 is a circular structure, and the central axes of the sleeve 6 and the movable block 4 coincide with each other.

[0023] The working principle and usage process of the present invention: The present invention adopts a movable block 4 and a sleeve 6 to rotationally connect the handwheel 5 and the manual valve stem 3, ensuring that the handwheel 5 will not cause the manual valve stem 3 to rotate and adjust when it is accidentally touched, thereby changing the working state of the valve body 1, thereby improving the reliability of the present invention. When manual operation is required, it is only necessary to press the handwheel 5 to make the movable block 4 slide in the sleeve 6, and insert the synchronization rod 10 into the synchronization groove 9 to connect the sleeve 6 and the movable block 4 together so that they rotate synchronously, and then drive the manual valve stem 3 to rotate and adjust through the handwheel 5. After the adjustment is completed, the top spring 7 applies elastic pushing action on the movable block 4, so that the movable block 4 slides toward the outer end of the sleeve 6 when there is no external force squeezing, so that the synchronization rod 10 automatically separates from the synchronization groove 9.
