[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] Example 1

[0028] An FC5000 horizontal main distribution non-off position switch bracket includes: a switch component 1, a switch bracket 2, a connecting rod 5 and a positioning adjustment component 8. One end of the connecting rod 5 is connected to the main distribution valve core, and the other end of the connecting rod 5 is inductively connected to the switch component 1. The switch bracket 2 is provided with a switch mounting hole, and the switch component 1 passes through the switch mounting hole. The positioning adjustment component 8 is respectively connected to the switch bracket 2 and the valve body of the main distribution valve core; wherein the positioning adjustment component 8 is used to adjust the relative position between the switch bracket 2 and the valve body and limit and fix the switch bracket 2. In this embodiment, the switch assembly 1 can be a main non-closed position switch, and the positioning condition assembly 8 can be a bolt; the switch assembly 1 adopts a normally open contact wiring. When the main valve core is in the middle position or moves in the open direction, the main valve core drives the connecting rod 5, and the connecting rod 5 drives the switch assembly 1 to move, and its normally open contact is closed, indicating that the main valve core is in the non-closed position; when the main valve core moves in the closing direction, the main valve core drives the connecting rod 5, and the connecting rod 5 drives the switch assembly 1 to move back, and its normally open contact is in the reset state, indicating that the main valve core is in the closed position.

[0029] In this embodiment, the switch bracket 2 is provided with a first positioning hole 4, and the valve body is provided with a bracket mounting hole corresponding to the first positioning hole 4. A positioning adjustment assembly 8 passes through the first positioning hole 4 and the bracket mounting hole, and the positioning adjustment assembly 8 is bolted to the valve body and the switch bracket 2. The first positioning hole 4 is a special-shaped hole, and its diameter is larger than that of the bracket mounting hole. Because the diameter of the first positioning hole 4 is larger than that of the bracket mounting hole, the relative position of the switch bracket 2 and the valve body can be adjusted to meet actual usage requirements by adjusting the relative position of the first positioning hole 4 and the bracket mounting hole and securing them with the positioning adjustment assembly 8.

[0030] Example 2

[0031] Reference Figure 1 Based on Example 1, in this embodiment, the switch bracket 2 is a frame structure. The switch bracket 2 is bilaterally symmetrical, with the switch mounting hole located in the center. Positioning adjustment assemblies 8 are symmetrically positioned on either side of the switch bracket 2. Furthermore, two symmetrical switch assemblies 1 can be provided, each with two symmetrical switch mounting holes formed in the switch bracket 2. This ensures that the detection positions of the switch assemblies 1 are consistent, thus resolving the issue of two main and auxiliary non-off switches being unable to operate simultaneously.

[0032] The switch bracket 2 includes: a crossbeam, a side plate, a bottom plate and a reinforcement plate. The center of the crossbeam is the symmetry center of the switch bracket 2. The two ends of the side plate are vertically connected to the crossbeam and the bottom plate respectively to form a stable side support. Figure 1 As shown, both ends of the reinforcing plate are respectively connected to the side plate and the bottom plate to form a diagonal rod structure, which improves the overall structural strength of the switch bracket 2 and also improves the seismic resistance of the switch bracket 2.

[0033] In this embodiment, the first positioning hole 4 can be a strip-shaped hole, the width of the first positioning hole 4 is adapted to the aperture of the bracket mounting hole, and the length of the first positioning hole 4 is greater than the aperture of the bracket mounting hole, allowing the relative position of the switch bracket 2 and the valve body to be adjusted within a certain range to adapt to different installation requirements.

[0034] In this embodiment, the aperture of the switch mounting hole is larger than the switch assembly 1, so that the relative position of the switch assembly 1 in the switch mounting hole can be adjusted, that is, the installation position of the switch assembly 1 can be changed, and the position of the switch assembly 1 can be adjusted in all directions such as up and down, left and right, and front and back as needed.

[0035] Example 3

[0036] Based on Examples 1 and 2, this embodiment further includes a base 6, which is disposed on the side of the valve body of the main valve core and can be secured by welding. A positioning adjustment assembly 8 is connected to the switch bracket 2 and the base 6, respectively. The positioning adjustment assembly 8 is used to adjust the relative position of the switch bracket 2 and the base 6 and to limit and secure the switch bracket 2. Since the base 6 is detachably mounted on the valve body, the base 6 need only be installed within the range of motion of the connecting rod 5. The installation position of the base 6 can be adjusted according to installation requirements, thereby adjusting the position of the switch bracket 2. This avoids a direct rigid connection between the switch bracket 2 and the valve body, thereby further improving seismic resistance.

[0037] Example 4

[0038] Based on Example 1, Example 2, and Example 3, this embodiment further includes an extension connection assembly 3, one end of which is connected to the switch assembly 1, and the other end of the extension connection assembly 3 is provided with a connecting rod mounting hole along the axial direction of the connecting rod 5, and a second positioning hole 7 is provided radially of the connecting rod mounting hole. The connecting rod 5 is slidably connected to the connecting rod mounting hole, and a positioning groove corresponding to the second positioning hole 7 is provided on the connecting rod 5. One end of the extension connection assembly 3 is connected to at least one switch assembly 1. By providing the extension connection assembly 3, the extension connection assembly 3 is used to connect one or more switch assemblies 1, and the number of switch assemblies 1 to be installed can be selected according to actual needs; the distance between the connecting rod 5 and the switch assembly 1 can be adjusted by the second positioning hole 7 and the positioning groove on the connecting rod, thereby adjusting the range of motion of the connecting rod 5, making the adjustment of the entire switch bracket 2 more flexible.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. 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.
