[0002] In the fields of industrial automation and fluid control, shut-off valves are important control components, and their performance and stability are crucial to the operation of the entire system. The shut-off valve's actuator is responsible for driving the valve open and closed. Therefore, the design of the actuator's fixed mounting components directly affects the shut-off valve's reliability and service life.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-4The utility model provides a technical solution: a fixed installation component of a shut-off valve actuator, including a valve body 110 and a support frame 120. The support frame 120 is U-shaped and has a positioning plate 130 symmetrically fixedly installed at both ends. A positioning groove 111 matching the positioning plate 130 is provided on one side of the valve body 110. The interior of the positioning plate 130 is hollow and a spring 131 is symmetrically fixedly installed on one side of the inner wall. A slide plate 132 is fixedly installed on one end of the spring 131. A plug rod 133 is symmetrically fixedly installed on one side of the slide plate 132. One end of the plug rod 133 slides through the positioning plate 130 and is inserted into the positioning groove 1 11 inner wall, a rotating shaft 121 is rotatably installed on one side of the inner wall of the support frame 120, and a cross plate 122 is fixedly installed on one end of the rotating shaft 121. A cross groove 123 matching the cross plate 122 is provided at one end of the valve stem of the valve body 110, and a driving assembly is installed on the rotating shaft 121. A reinforcing plate 124 is symmetrically fixedly installed between the positioning plate 130 and the support frame 120, and the reinforcing plate 124 is inclined. The positioning plate 130 is slidably connected to the inner wall of the positioning groove 111, and a slot matching the insertion rod 133 is provided on the inner wall of the positioning groove 111, and the slot is provided on the side relatively far away from the two positioning grooves 111.

[0027] In some specific embodiments, the guide rods 134 and the support blocks 135 are symmetrically fixedly installed on the inner wall of the positioning plate 130, and the slide plate 132 is slidably installed on the guide rods 134 and the support blocks 135. The guide rods 134 are symmetrically arranged on both sides of the support blocks 135. This design enhances the stability and sliding smoothness of the slide plate 132. The arrangement of the guide rods 134 and the support blocks 135 ensures that the slide plate 132 will not deviate or get stuck during movement, thereby improving the accuracy and reliability of the entire fixed installation assembly.

[0028] In some specific embodiments, a push plate 136 is fixedly installed on one side of the skateboard 132, and one end of the push plate 136 slides through the positioning plate 130 and extends to the outside. A strip hole matching the push plate 136 is provided on one side of the positioning plate 130, and the push plate 136 is slidably connected to the inner wall of the strip hole, which provides a convenient operation method for the user. The user can easily control the movement of the skateboard 132 by pushing the push plate 136, and then control the extension and retraction of the insertion rod 133. This design simplifies the operation process and improves work efficiency.

[0029] See also Figure 4 The driving assembly includes a cylinder 140, a rack 141 and a gear 142. A quadrangular prism 143 is fixedly installed between the two sides of the inner wall of the support frame 120. The rack 141 is slidably installed on the quadrangular prism 143. The gear 142 is fixedly installed on the rotating shaft 121. The gear 142 is meshed with the rack 141. A horizontal plate 144 is fixedly installed on one side of the rack 141. The cylinder 140 is fixedly installed on the inner wall of the support frame 120. The output end of the cylinder 140 is fixedly connected to one side of the horizontal plate 144, and the horizontal plate 144 is slidably connected to one side of the inner wall of the support frame 120.

[0030] In some specific embodiments, rack 141 and cylinder 140 are symmetrically arranged on support frame 120. This design enables automated control and greatly improves work efficiency. Furthermore, cylinder 140, as a power source, has advantages such as high output force and smooth operation, making the operation of the entire fixed installation assembly more stable and reliable.

[0031] In some specific implementation schemes, a limit plate is fixedly installed on one side of the horizontal plate 144, and a limit groove 145 matching the limit plate is provided on one side of the inner wall of the support frame 120. The limit plate is slidably connected to the inner wall of the limit groove 145, and the cross-section of the limit plate is T-shaped. This design limits the movement range of the horizontal plate 144, thereby ensuring the stability and accuracy of the rack 141 during the sliding process. The cooperation between the limit plate and the limit groove 145 also prevents the rack 141 from falling off, further improving the safety and reliability of the entire fixed installation assembly.

[0032] Working principle: When in use, the push plates 136 on both sides are pressed relative to each other to drive the slide plate 132 to move, and the movement of the slide plate 132 drives the insertion rod 133 to move and retract into the positioning plate 130 and squeeze the spring 131. At this time, the positioning plates 130 at both ends of the support frame 120 are inserted into the positioning groove 111, and the cross plate 122 is inserted into the cross groove 123 of the valve stem, and the push plate 136 is released. The elastic force of the spring 131 drives the slide plate 132 to move back, and the movement of the slide plate 132 drives the insertion rod 133 to be inserted into the slot and fixed. When the valve body 110 needs to be adjusted, it is only necessary to start the cylinder 140. The cylinder 140 drives the rack 141 to move through the cross plate 144. The rack 141 moves and cooperates with the gear 142 to drive the rotating shaft 121 to rotate. The rotating shaft 121 rotates and drives the valve stem to rotate through the cross plate 122 and the cross groove 123.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
