[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] As shown in the figure, a valve actuator installation structure includes a valve actuator body 1. Water pipes 2 are fixedly connected to the water passages at both ends of the valve actuator body 1. Connecting discs 3 are circumferentially fixed to the water passages at both ends of the valve actuator body 1 and the end of the water pipes 2 facing the valve actuator body 1. Connecting components 4 are fixedly connected between the two connecting discs 3 on the same side of the valve actuator body 1. The connecting components 4 include a lower connecting piece 41 and an upper connecting piece 42 that are fixed together and are both semi-circular rings. The lower connecting piece 41 is snapped and fixed between the lower parts of the corresponding two connecting discs 3. A filter screen 43 is fixedly connected to the inner wall of the upper connecting piece 42. The upper connecting piece 42 is fixed between the upper parts of the corresponding two connecting discs 3, and the lower part of the filter screen 43 is inserted into the inner wall of the lower connecting piece 41. In this embodiment, connecting discs 3 are fixedly connected to both ends of the valve actuator body 1 and the ends of the water pipes 2 connected to both ends of the valve actuator body 1. The two connecting discs 3 on each side are fixed together by connecting components 4. The upper side of the connecting components 4 is provided with a detachable filter screen 43 and an upper connector 42 for installing the filter screen 43, and the lower side is provided with a lower connector 41 for inserting the lower part of the filter screen 43. The upper connector 42 and the lower connector 41 together fix the two connecting discs 3 on each side. At the same time, the filter screen 43 filters impurities from the fluid, making it easy to disassemble and clean the filter screen 43 at any time.

[0027] The lower connector 41 has arc-shaped locking edges 411 fixed outward on both sides. On the connecting plate 3, a locking groove 31 is opened at the corresponding locking edge 411. The locking edge 411 is locked into the corresponding locking groove 31, and a first sealing gasket (not shown in the figure) is fixed in the locking groove 31. The locking edge 411 abuts against the first sealing gasket in the locking groove 31. The lower connector 41 is fixed together with the two corresponding connecting plates 3 below the locking edge 411 by multiple first bolt and nut pairs 5. In this embodiment, the lower connector 41 is engaged with the two connecting discs 3 by the snap-fit ​​edges 411 on both sides and the snap-fit ​​grooves 31 on the corresponding two connecting discs 3. While the lower connector 41 is being pressed together by the two connecting discs 3, it also works with the snap-fit ​​edges 411 and the snap-fit ​​grooves 31 to limit its position, which facilitates the disassembly and assembly of the first bolt and nut assembly 5 without the lower connector 41 accidentally separating from the connecting discs 3. This effectively improves the connection stability of the lower connector 41 and also increases the sealing between the lower connector 41 and the connecting discs 3.

[0028] A frame 431 is fixedly attached to the outer periphery of the filter screen 43. A semi-annular upper groove 421 is formed on the inner sidewall of the upper connector 42, and a semi-annular lower groove 412 is formed on the inner sidewall of the lower connector 41. The upper part of the frame 431 is inserted into the upper groove 421 and fixed to the sidewall of the upper connector 42 by multiple screws 44. The lower part of the frame 431 is inserted into the lower groove 412. In this embodiment, when the upper connector 42 is removed from this structure, the filter screen 43 is also removed, which facilitates cleaning of the filter screen 43.

[0029] A second sealing gasket (not shown in the figure) is fixedly connected in both the upper groove 421 and the lower groove 412. The outer wall of the frame 431 and the second sealing gaskets in the upper groove 421 and the lower groove 412 are tightly abutted together to increase the sealing between the frame 431 and the upper connector 42 and the lower connector 41.

[0030] Both sides of the upper connector 42 are fixedly connected with arc-shaped protrusions 422. Each connecting plate 3 has an installation groove 32 on the upper part of the side facing the upper connector 42, and the upper opening of the installation groove 32 penetrates the upper outer wall of the connecting plate 3. The protrusions 422 of the upper connector 42 overlap and press against the bottom side wall of the corresponding installation groove 32. The upper connector 42 is fixed to the two corresponding connecting plates 3 above the protrusions 422 by multiple second bolt and nut pairs 6. In this embodiment, the protrusions 422 are provided on both sides of the upper connector 42. When the connector 42 is installed downwards, the protrusions 422 enter the installation groove 32 downwards until they are pressed against the bottom of the installation groove 32. Then, the upper connector 42 and the two connecting plates 3 are fixed by the second bolt and nut pairs 6, which effectively improves the sealing between the upper connector 42 and the connecting plates 3.

[0031] A third sealing gasket (not shown in the figure) is fixed to the inner wall of the protruding edge 422, and the protruding edge 422 is pressed against the side wall of the mounting groove 32 by the third sealing gasket.

[0032] The lower connector 41 has a lower fixing platform 413 with both ends of the opening facing outward horizontally, and the upper connector 42 has an upper fixing platform 424 with both ends of the opening facing outward horizontally. A third sealing gasket is fixedly connected to the upper side of each lower fixing platform 413, and the upper fixing platform 424 and the corresponding lower fixing platform 413 are fixed together by a third bolt and nut pair 7, which effectively improves the sealing performance at the joint between the lower connector 41 and the upper connector 42.

[0033] A pull ring 423 is fixedly connected to the upper side of the upper connector 42, which facilitates the installation and removal of the upper connector 42 and the filter screen 43 on the valve actuator mounting structure.

[0034] In this embodiment, the lower connector 41, the snap-fit ​​edge 411, and the lower fixing platform 413 are integrally formed structures; the upper connector 42, the protruding edge 422, and the upper fixing platform 424 are integrally formed structures.

[0035] In this embodiment, during installation, the lower connector 41 is first snapped between the two connecting discs 3 by the engagement of the snap-fit ​​edge 411 and the snap-fit ​​groove 31. Then, the lower connector 41 and the two connecting discs 3 are initially fixed by the first bolt and nut pair 5. Next, the upper connector 42, on which the filter screen 43 is installed, is inserted downward between the two connecting discs 3 until the lower part of the filter screen 43 abuts against the lower groove 412 of the lower connector 41. At the same time, the protruding edge 422 of the upper connector 42 is pressed against the bottom side of the mounting groove 32. Then, the upper connector 42 and the two connecting discs 3 are initially fixed by the second bolt and nut pair 6. The upper connector 42 and the lower connector 41 are fixed by the third bolt and nut pair 7. Finally, the first bolt and nut pair 5, the second bolt and nut pair 6, and the third bolt and nut pair 7 are finely adjusted to ensure that they are all tightly connected.

[0036] When the filter screen 43 needs to be removed for cleaning, simply remove the second bolt and nut assembly 6 and the third bolt and nut assembly 7, lift the upper ring 423, and remove the upper connector 42 from the two connecting discs 3 to detach the filter screen 43 from the lower connector 41. Then the filter screen 43 can be cleaned.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
