Technical Field

[0001] This utility model relates to the field of valve fittings technology, and in particular to a universal valve feedback connector. Background Technology

[0002] In traditional industrial production scenarios, there are a large number of valves. Valves and positioners come in many varieties, and it is often impossible to ensure that the brands and specifications are consistent when purchasing them. Therefore, maintenance personnel will purchase different types of positioners as spare parts.

[0003] Currently, existing valve fittings have been found to have at least the following technical problems during actual use;

[0004] Due to various reasons such as cost and storage, it is difficult to ensure that there are enough spare parts for all types of positioners on site. Therefore, when a positioner fails and needs to be replaced, there will be problems such as poor compatibility and difficulty in installation when replacing it with a positioner of different specifications. Utility Model Content

Four threaded holes are distributed on the surface of the fixed base, and each of the four threaded holes is threaded with a locking screw. The feedback mechanism includes a first tightening nut and a height adjusting screw. A square column is fixedly mounted on the top of the height adjusting screw, and a transmission rod mounting plate is provided on the surface of the square column. A retaining spring is provided at one end of the height adjusting screw that passes through the transmission rod mounting plate. A transmission rod body is provided at the end of the transmission rod mounting plate away from the height adjusting screw. A transmission rod tightening nut is threadedly connected to the connection between the transmission rod body and the transmission rod mounting plate.

[0008] Preferably, a threaded hole is provided at the center of the top surface of the fixed base, and the height adjustment screw is threadedly connected to the threaded hole.

[0009] Preferably, the portion where the height adjusting screw connects to the threaded hole is threadedly connected to the first tightening nut.

[0022] This application provides a universal valve feedback connector, which effectively solves the problem of existing valves and positioners lacking compatible structures and being difficult to install. Example

[0023] like Figures 1-4As shown, the technical solution in this application embodiment effectively solves the technical problem of existing valves and positioners lacking adaptable structures and being difficult to install. The overall idea is as follows:

[0024] To address the problems existing in the prior art, this utility model provides a universal valve feedback connector, including a fixed base 1, a cavity on the inner side of the fixed base 1, a feedback mechanism on the top surface of the fixed base 1, and four threaded holes distributed on the surface of the fixed base 1, each threaded hole being threadedly connected to a locking screw 2. The feedback mechanism includes a first tightening nut 3 and a height adjusting screw 4. A square column is fixedly mounted on the top of the height adjusting screw 4, and a transmission rod mounting plate 6 is mounted on the surface of the square column. A retaining spring 5 is mounted on one end of the height adjusting screw 4 that passes through the transmission rod mounting plate 6. A transmission rod body 8 is mounted on the end of the transmission rod mounting plate 6 away from the height adjusting screw 4, and a transmission rod tightening nut 7 is threadedly connected to the connection between the transmission rod body 8 and the transmission rod mounting plate 6.

[0025] A threaded hole is provided at the center of the top surface of the fixed base 1, and the height adjustment screw 4 is threadedly connected to the threaded hole.

[0026] The height adjustment screw 4 is connected to the threaded hole and the first tightening nut 3 by thread.

[0027] The height adjustment screw 4 has a slot in the middle section of the square column.

[0028] The transmission rod mounting plate 6 is sleeved with the square column, and the retaining spring 5 is engaged with the retaining groove of the square column. The retaining spring 5 is C-shaped.

[0029] The transmission rod mounting plate 6 has a through hole at the end away from the height adjustment screw 4, and the transmission rod body 8 is inserted into the inside of the through hole.

[0030] Fixed base 1: It is installed on the feedback shaft at the top of the valve cylinder through a cavity, and is fixed to the feedback shaft by four threaded holes and locking screws 2, providing a support foundation for the entire device.
