Description

Technical Field

[0001] This utility model relates to the field of valve actuator technology, and specifically to a valve actuator that is easy to install. Background Technology

[0002] The core function of a valve actuator is to convert control signals into mechanical force to drive the valve to complete opening, closing, or regulation actions, thereby achieving automated control of fluid pipelines.

[0003] In the prior art, such as the valve actuator that is easy to install according to the announcement number CN221075421 U, there is a valve actuator body, and a pipe body is connected to the bottom of the valve actuator body. A positioning mechanism is provided between the valve actuator body and the pipe body. The positioning mechanism includes a sleeve that is fixedly connected to the bottom of the outer wall of the valve actuator body. Two positioning grooves are opened on the top of the outer wall of the pipe body. Positioning blocks are inserted through the inner wall of each positioning groove. A retaining ring is fixedly provided on the top of each positioning block. A connecting block is fixedly provided on the top of each retaining ring. A fixing block is fixedly provided on the top of each outer wall of the pipe body. A splicing groove is opened on one end of each fixing block.

[0004] In the above, when the valve actuator body is aligned with the pipe body by hand, the positioning and guidance effect between the valve actuator body and the pipe body is achieved. However, after reading the technical solution, it is known that the valve pipe body usually rotates. This method of inserting the groove and block can only ensure a stable connection effect in a straight line. When faced with the centrifugal force generated by the rotational motion, the direct insertion method will cause the groove and block to be pushed off, thus affecting the stability of the pipe body during rotation. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a valve actuator that is easy to install, which can effectively solve the problem that the direct insertion method in the existing technology will affect the stability of the pipe body during rotation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a valve actuator that is easy to install, including a valve, an intermediate shaft fixedly connected to the middle of the valve, a wrapping sleeve sleeved on the outer surface of the intermediate shaft, and an alignment and installation component in cooperation with the wrapping sleeve;

[0008] The alignment and installation assembly includes a contact ball that movably abuts against the outer surface of the packaging tube. A slide rod is fixedly connected to the outer surface of the contact ball. A straight spring is adapted to be installed on the top of the slide rod. A connecting seat is fixedly connected to one end of the straight spring. An outer cylinder is slidably fitted to the outer side of the slide rod. Multiple fitting cavities are opened on the inner side of the outer cylinder. Alignment blocks are movably engaged in the fitting cavities. The alignment blocks are fixedly installed on the outer wall of the slide rod.

[0009] Furthermore, a protruding seat is fitted onto the surface of the slide rod, and a connecting rod is hinged to the protruding seat. A positioning block is installed on the top of the connecting rod, and the positioning block is fixedly connected to the inner side of the connecting seat.

[0010] Furthermore, the number of the alignment blocks is several, and the several alignment blocks are equidistantly distributed.

[0011] Furthermore, the number of the alignment mounting components is several, and the several alignment mounting components are arranged in a ring array on the outside of the wrapping tube.

[0012] Furthermore, the connecting seat is equipped with a rotating fitting assembly, which includes a top ring placed on the outside of the connecting seat. A straight shaft is adapted to be installed on the inner side of the top ring. An angle tooth is rotatably sleeved on the outer surface of the straight shaft.

[0016] Beneficial effects

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] 1. By installing an intermediate shaft in the middle of the valve, the valve can achieve the functions of opening and closing. A wrapping cylinder is installed on the outside of the intermediate shaft, and a contact ball is installed on the outer surface of the wrapping cylinder. When the valve rotates, the centrifugal force generated will push the contact ball and cause the contact ball and slide rod to move radially. Under this action, the straight spring compresses itself and undergoes elastic deformation. The elastic force generated will act on the contact ball, so that the contact ball will abut against the surface of the wrapping cylinder in real time. This can be used to stabilize the valve itself when it rotates. Then, the alignment block on the outside of the slide rod is engaged with the adapter cavity, making the slide rod more stable during radial displacement and preventing the displacement direction from deviating. From the perspective of the motion mode, this unidirectional displacement motion can form multiple support points on the outer surface of the wrapping cylinder, thereby counteracting the centrifugal force generated when the valve rotates and meeting the requirements for valve rotation stability.

[0019] Second, during the displacement process of the slide rod, the connecting rod will rotate hinged on the surface of the protruding seat. The torque generated during the rotation will reduce the lateral displacement of the slide rod, thereby improving the support efficiency for the valve. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] See attached document Figure 1-5 A valve actuator that is easy to install includes a valve 1, an intermediate shaft 2 fixedly connected to the middle of the valve 1, a wrapping sleeve 3 sleeved on the outer surface of the intermediate shaft 2, and an alignment and installation component 4 fitted to the wrapping sleeve 3.

[0030] The alignment and installation assembly 4 includes a contact ball 41 that movably abuts against the outer surface of the wrapping tube 3. A slide rod 42 is fixedly connected to the outer surface of the contact ball 41. A straight spring 43 is fitted to the top of the slide rod 42. One end of the straight spring 43 is fixedly connected to a connecting seat 5. An outer cylinder 44 is slidably fitted to the outer side of the slide rod 42. Multiple fitting cavities 46 are opened on the inner side of the outer cylinder 44. An alignment block 45 is movably engaged in the fitting cavity 46. The alignment block 45 is fixedly installed on the outer wall of the slide rod 42. A protruding seat 47 is fitted to the surface of the slide rod 42. A connecting rod 48 is hinged to the protruding seat 47. A positioning block 49 is installed on the top of the connecting rod 48. The positioning block 49 is fixedly connected to the inner side of the connecting seat 5.

[0031] By installing an intermediate shaft 2 in the middle of valve 1, valve 1 can achieve the functions of opening and closing. A wrapping cylinder 3 is installed on the outside of the intermediate shaft 2. The outer surface of the wrapping cylinder 3 abuts against the contact ball 41. When valve 1 rotates, the centrifugal force generated will push the contact ball 41 and cause the contact ball 41 and slide rod 42 to move radially. Under this action, the straight spring 43 undergoes elastic deformation after compression, and the generated elastic force reacts on the contact ball 41, so that the contact ball 41 abuts against the surface of the wrapping cylinder 3 in real time. This can be used to stabilize valve 1 when it rotates. Afterwards, the alignment block 45 on the outside of slide rod 42 is movably engaged with the adapter cavity 46, making slide rod 42 more stable during radial displacement and preventing the displacement direction from deviating. From the perspective of the movement mode, this unidirectional displacement movement can form multiple support points on the outer surface of the wrapping cylinder 3, thereby counteracting the centrifugal force generated when valve 1 rotates and meeting the rotational stability requirements of valve 1.

[0032] During the displacement of the slide rod 42, the connecting rod 48 will hinge and rotate on the surface of the protruding seat 47. The torque generated during the rotation will reduce the lateral displacement of the slide rod 42, thereby improving the support efficiency of the valve 1.

[0033] There are several alignment blocks 45, which are equidistantly distributed. There are also several alignment mounting components 4, which are arranged in a ring array outside the wrapping tube 3.

[0034] At the same time, the arrangement of several alignment mounting components 4 and alignment blocks 45 can significantly expand the support range of the outer side of the wrapping cylinder 3. In terms of range, expanding the support range can limit the position of the wrapping cylinder 3, thereby indirectly ensuring the relative stability of the rotation position of the valve 1.

[0035] The connecting seat 5 is fitted with a rotating fitting assembly 6. The rotating fitting assembly 6 includes a top ring 61 placed on the outside of the connecting seat 5. A straight shaft 64 is fitted on the inner side of the top ring 61. An angle tooth 63 is rotatably sleeved on the outer surface of the straight shaft 64. A wedge tooth 62 is movably engaged on the side of the angle tooth 63. The wedge tooth 62 is fixedly installed on the outer wall of the connecting seat 5. The engagement angle between the angle tooth 63 and the wedge tooth 62 is an acute angle.

[0036] When valve 1 rotates, it drives connecting seat 5 to rotate synchronously. The wedge-shaped teeth 62 located on the inner side of connecting seat 5 contact and mesh with the angle teeth 63. At the same time, under the support of the straight shaft 64, the meshing between the angle teeth 63 and the wedge-shaped teeth 62 is more durable, forming more inner support surfaces on the inner side of connecting seat 5, thereby ensuring that the connection between connecting seat 5 and valve 1 will not disengage, and further improving the rotational stability of the overall device.

[0037] The top of the top ring 61 is fitted with an adapter 7. A pressure measuring assembly 8 is provided through the surface of the adapter 7. A pressure measuring head 9 is inserted into the outer surface of the pressure measuring assembly 8. An inner fixed plate 10 is movably snapped into the top of the adapter 7. An actuator 11 is installed on the top of the inner fixed plate 10. The actuator 11 is electrically connected to the intermediate shaft 2.

[0038] Finally, the pressure testing assembly seat 8 that penetrates the surface of the adapter seat 7, and the pressure testing head 9 that is installed, can perform pressure testing on the valve 1. Then, by fixing the actuator 11 in the inner fixed plate 10, the power source required for the rotation of the intermediate shaft 2 is provided to meet the rotation and closing requirements of the valve 1.

[0039] Working principle: A wrapping cylinder 3 is installed on the outside of the intermediate shaft 2. The outer surface of the wrapping cylinder 3 abuts against the contact ball 41. When the valve 1 rotates, the centrifugal force generated will push the contact ball 41 and cause the contact ball 41 and the slide rod 42 to move radially. Under this action, the straight spring 43 compresses itself and undergoes elastic deformation. The elastic force generated reacts on the contact ball 41, so that the contact ball 41 abuts against the surface of the wrapping cylinder 3 in real time. This can be used to stabilize the valve 1 itself when it rotates.

[0040] Then, by setting up several alignment mounting components 4 and alignment blocks 45, the support range of the outer side of the wrapping cylinder 3 can be significantly expanded. In terms of the range, expanding the support range can limit the position of the wrapping cylinder 3, thereby indirectly ensuring the relative stability of the rotation position of the valve 1.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
