[0032] Referring to Figures 1-5 , the utility model discloses a flowmeter sealing structure, including: filling sleeve 2, the rear end of filling sleeve 2 is slidably connected with the conveying pipeline 4, the front end of conveying pipeline 4 is fixedly connected with first connector 7, the front end of first connector 7 is provided with the accommodation groove 9, the bottom of accommodation groove 9 is fixedly connected with first magnet 10, the lower end of filling sleeve 2 is threadedly connected with limit sleeve 11, the inner wall of limit sleeve 11 is slidably connected with second connector 20, the inner wall of second connector 20 is fixedly connected with flowmeter pipeline 1, the front end of limit sleeve 11 is fixedly connected with second magnet 12, the upper end of filling sleeve 2 is connected with injection filling port 3, the upper end of injection filling port 3 is threadedly connected with threaded plug 6, the outside of second connector 20 is provided with second sliding groove 18, the inner wall of second sliding groove 18 is slidably connected with first sliding block 19, the upper end of first sliding block 19 is fixedly connected with limit sleeve 11, the outside of limit sleeve 11 is placed with rubber ring 17, the front end of rubber ring 17 is in close contact with filling sleeve 2, the outside of second magnet 12 is in contact with accommodation groove 9, the front end of second magnet 12 is magnetically connected with first magnet 10, the front end of limit sleeve 11 is provided with limit mechanism, and filling sleeve 2 is filled with sealing paste 5 between first connector 7 and limit sleeve 11 respectively.

[0033] Limit mechanism includes limit piece 13, limit rod 14, first sliding groove 15, spring 16 and second sliding block 21, the upper end of first connector 7 is provided with limit hole 8, the inner wall of limit hole 8 is in close contact with limit rod 14, first sliding groove 15 is located in the inside of limit piece 13, the inner wall of first sliding groove 15 is slidably connected with second sliding block 21, the lower end of limit rod 14 is fixedly connected with second sliding block 21, and the lower end of second sliding block 21 is elastically connected with spring 16.

[0034] Working principle: when installing, first, the first connector 7 fixedly connected with the front end of the conveying pipeline 4 is close to the limit sleeve 11, so that the first magnet 10 at the bottom of the accommodation groove 9 of the first connector 7 and the second magnet 12 at the front end of the limit sleeve 11 are close to each other and contact, the magnetic force between the two magnets is used to quickly and accurately complete the preliminary alignment of the first connector 7 and the limit sleeve 11, lay the foundation for subsequent connection operation, and guarantee the accuracy and stability of the connection to a certain extent, reduce the installation problems caused by position deviation.

[0035] After the initial alignment is completed, press the limiting rod 14 in the limiting mechanism, the lower end of the limiting rod 14 is fixedly connected with the second sliding block 21, the second sliding block 21 is located in the first sliding groove 15 inside the limiting piece 13, and is elastically connected with the spring 16. When the limiting rod 14 is pressed, the elastic force of the spring 16 is overcome, so that the second sliding block 21 slides upward in the first sliding groove 15. When the relative position of the first connecting head 7 and the limiting sleeve 11 is adjusted to the best state, the pressure on the limiting rod 14 is released. Under the elastic restoring force of the spring 16, the limiting rod 14 moves downward and accurately enters the limiting hole 8 preset on the upper end of the first connecting head 7. This operation effectively prevents the limiting sleeve 11 from rotating or axially moving relative to the first connecting head 7 during subsequent operation, further stabilizing the connection between the two.

[0036] After the limiting rod 14 successfully enters the limiting hole 8 and is fixed, the connection operation of the filling sleeve 2 is started. Since the rear end of the filling sleeve 2 is connected with the conveying pipeline 4 in a sliding manner, the filling sleeve 2 can be slid flexibly according to the actual installation space and needs, so that its lower end is threadedly connected with the limiting sleeve 11. During the rotation of the filling sleeve 2 to tightly screw it with the limiting sleeve 11, the front end of the filling sleeve 2 gradually approaches and tightly contacts the rubber ring 17 placed outside the limiting sleeve 11. The rubber ring 17 has good elasticity and will be elastically deformed when it is pressed by the front end of the filling sleeve 2. It can preliminarily fill the small gap between the filling sleeve 2 and the limiting sleeve 11 and play a certain sealing role.

[0037] After the filling sleeve 2 is threadedly connected with the limiting sleeve 11 and the front end of the filling sleeve 2 tightly contacts the rubber ring 17, although a certain sealing structure has been formed, in order to further improve the sealing performance of the entire flowmeter sealing structure to meet the fluid conveying needs under different working conditions, the injection operation of the sealing paste 5 is needed. The threaded plug 6 on the injection filling port 3 connected with the upper end of the filling sleeve 2 is unscrewed, a special injection device is connected to the injection filling port 3, and the sealing paste 5 is injected into the filling sleeve 2 from the injection filling port 3 by applying pressure with the injection device. Under the action of pressure, the sealing paste 5 can be uniformly filled into the gap between the filling sleeve 2 and other internal components such as the first connecting head 7 and the limiting sleeve 11. After the sealing paste 5 solidifies, it can form a solid and well-sealed barrier, which, together with the rubber ring 17, greatly improves the sealing performance of the entire flowmeter sealing structure, effectively prevents fluid leakage at the connection, and ensures that the fluid can flow stably and smoothly in the flowmeter pipeline 1 and the conveying pipeline 4, thereby ensuring the accuracy and reliability of the flow measurement work.

[0038] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
