Description

Technical Field

[0001] The utility model relates to the field of flat valve control, in particular to a combined switch actuator. Background Art

[0002] The flat plate valve is a common type of industrial valve, also known as a plate valve. It is usually used to control the flow of fluid (liquid or gas), and plays a role in regulating, cutting off or controlling the flow direction of fluid in the pipeline system.

[0003] A flat plate valve is usually composed of a valve body, a valve disc, a valve stem and other basic components. When used in daily connection with liquid and gas pipelines, most of the time, the valve disc is rotated manually to control the valve stem to drive the valve body to open or close. For this reason, an electronic control unit controller is currently introduced to control the closing and opening of the flat plate valve.

[0004] However, when the existing electronic control unit controller operates the flat valve, it is necessary to change the structure of the flat valve according to the type of the flat valve, so as to realize the electronic control of the flat valve. However, its practicality is poor and it cannot be applied to some common flat valves. Therefore, a combined switch actuator is proposed to solve the above problem. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3 The utility model provides an embodiment of a combined switch actuator, comprising a mounting seat 1, a connecting plate 5 is fixed at the bottom end of the outer wall of the mounting seat 1, and the inner wall of the mounting seat 1 is threadedly connected with multiple groups of threaded rods 2, and the bottom ends of the outer walls of the multiple groups of threaded rods 2 are fixedly connected with clamping blocks 3. By rotating the multiple groups of threaded rods 2, the multiple groups of clamping blocks 3 can be moved relative to each other, so as to be connected and fixed with the same flat valve surface on the market, and the bottom end of the outer wall of the connecting plate 5 is rotatably connected with a rotating plate 6, and the top end of the outer wall of the connecting plate 5 is detachably installed with a sensor 4 through a bolt, and the sensor 4 is electrically connected to the rotating plate 6, and the electrical connection between the two can control the rotating plate 6 to rotate through the sensor 4, so that the circular handle of the flat valve is automatically closed or opened through two groups of positioning rollers 81, and the slider 71 is slidably connected to the inner wall at the bottom end of the rotating plate 6, and the inner wall of the rotating plate 6 is provided with a guide groove that fits the slider 71, so that the slider 71 can only move on the inner wall of the rotating plate 6.

[0034] Reference Figure 2-Figure 3The cam 72 is provided with a locking plate 77 for locking the locking plate 74 so as to lock the locking plate 70 in the locking position.

[0035] Reference Figure 2-Figure 5 The positioning assembly 8 includes a positioning roller 81. The positioning roller 81 is provided with two groups, one group is connected to the slider 71, and the other group can be directly connected to the connecting plate 5. The inside of the connecting plate 5 is also provided with a bottom end of the positioning roller 81 and a corresponding card slot of the pressing block 82. The surface of the slider 71 is provided with a cavity. The bottom end of the outer wall of the positioning roller 81 contacts the inner wall of the cavity of the slider 71. The contact between the two can position and fix the installation position of the positioning roller 81. The inner wall of the positioning roller 81 is elastically fixed by the reset spring 83. A pressing block 82 is connected, one end of a return spring 83 is fixedly connected to the outer wall of the pressing block 82, and the other end of the return spring 83 is fixedly connected to the inner wall of the positioning roller 81. The function of the return spring 83 is to reset the position of the pressing block 82 after it moves. The pressing block 82 is slidably connected to the inner wall of the positioning roller 81, and a slot is provided on the inner wall of the slider 71. The bottom end of the outer wall of the pressing block 82 is plugged into the inner wall of the slot. The plugging between the two fixes the positioning roller 81 on the inner wall of the slider 71 to prevent it from falling off during use.

[0036] Working principle: when used on a flat valve, multiple groups of threaded rods 2 can be rotated to bring multiple groups of clamping blocks 3 closer to each other, thereby fixing the whole on the outer wall of the flat valve. At this time, the positions of the two groups of positioning rollers 81 can be adjusted according to the width of the connecting column of the flat valve handle. At this time, the plug block 73 can be pulled to make its bottom end disengage from the through hole at the current position of the connecting disk 6, and the plug block 73 will cause the limit spring 72 to be elastically compressed during the movement. At this time, the slider 71 can be directly moved to drive the positioning rollers 81 on its surface to move, thereby adjusting the distance between the two groups of positioning rollers 81, and after the adjustment is completed, the plug block 73 is released and it will be elastically acted upon by the limit spring 72 to restore it to its initial position, thereby plugging into the through hole at the current position of the connecting disk 6, thereby fixing the positioning roller 81 connected to the slider 71.

[0037] At the same time, the pressing block 82 can also be moved on the inner wall of the positioning roller 81, so that its bottom end can be disengaged from the through hole at the current position of the connecting disk 6, and the reset spring 83 can be elastically compressed, and the bottom end of the pressing block 82 can be disengaged from the through hole inside the slider 71, so that the positioning roller 81 can be taken out, making it convenient to disassemble and replace it.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
