The adjusting sleeve is in transmission fit with the limiting sleeve through the external thread structure, so that the adjusting sleeve rotates and the limiting sleeve moves up and down. Because the position of the adjusting sleeve is fixed relative to the shaft sleeve, in order to drive the flashboard to move up and down to realize the opening or closing of the valve, the flashboard is matched with the internal thread of the hollow structure at the lower part of the adjusting sleeve through a screw rod, and the screw rod moves up and down along the axial direction of the adjusting sleeve along with the rotation of the adjusting sleeve.
The utility model has the beneficial effects that:
1. after the valve is completely opened or closed, the upper limit switch or the lower limit switch is triggered, at the moment, the upper limit switch sends a valve body complete opening signal, or the lower limit switch sends a valve body complete closing signal, an operator does not need to carefully observe according to the received signal, and the operator can judge whether the valve is completely opened or completely closed according to working experience, so that the operation convenience and accuracy are relatively better.
2. The display is arranged on the outer wall of the shaft sleeve and used for receiving signals sent by the upper limit switch and the lower limit switch, and when the valve body is completely opened, the corresponding opening indicator lamp is lightened; when the valve body is completely closed and the corresponding closing indicator lamp is lightened, the opening and closing of the valve can be judged according to the conditions of the two indicator lamps, and the operation is particularly convenient at night.

The stop collar 10 is raised or lowered in response to rotation of the adjustment collar 50. Specifically, when the adjusting sleeve 50 rotates to realize the opening of the valve, the stop collar 10 moves upwards, and when the valve is completely opened, the contact 20 triggers the upper limit switch 30, and at this time, the upper limit switch 30 sends a valve complete opening signal, and an operator can know that the valve is completely opened according to the signal, and does not need to further perform opening operation.
When the adjusting sleeve 50 rotates to realize the closing of the valve, the limiting sleeve 10 moves downwards, when the valve is completely closed, the contact 20 triggers the lower limiting switch 40, and at the moment, the lower limiting switch 40 sends a valve complete closing signal, and an operator can know that the valve is completely opened according to the signal, and the closing operation is not needed.
Through the structural design, operators do not need to visually observe, and whether the valve is completely opened or completely closed is judged according to working experience, so that the operation convenience and accuracy are relatively better.
In addition, the top end of the adjusting sleeve 50 is fixedly connected with the hand wheel a so as to drive the adjusting sleeve 50 to rotate through the hand wheel a. The bottom end of the shaft sleeve 60 is still connected with a bearing seat b for fixing the adjusting set 50. The structure and the connection relation are the same as those of the existing valve, and are not changed. Wherein the bearing seat b is not fully shown in the figures.

And when the lower limit switch 40 is triggered by the contact 20, the corresponding turn-off indicator light 72 is turned on after the display 70 receives the information. The operating personnel can judge the opening and closing conditions of the valve according to the conditions of the two indicator lamps, so that the operation of the valve is convenient. The operation is particularly convenient at night.
With continued reference to FIG. 3, in one embodiment, the sleeve 60 is a unitary body of two sleeves that are flanged.
In order to facilitate the processing, assembly and later maintenance of the shaft sleeve 60, the shaft sleeve 60 is designed into a split structure, the two sleeve bodies are more convenient to process the limit groove 61 at the corresponding position, the upper limit switch 30 and the lower limit switch 40 are also respectively placed in the two sleeve bodies, and the installation of the switch is also more convenient. During later maintenance, the two sleeve bodies can be separated for overhauling.

The adjusting sleeve 50 is in transmission fit with the limiting sleeve 10 through an external thread structure, so that the adjusting sleeve 50 rotates and the limiting sleeve 10 moves up and down. Because the adjusting sleeve 50 is fixed relative to the shaft sleeve 60, and in order to drive the flashboard 12 to move up and down to realize the opening or closing of the valve, the flashboard 12 is matched with the internal thread of the hollow structure at the lower part of the adjusting sleeve 50 through the screw 11, and the screw 11 moves up and down along the axial direction of the adjusting sleeve 50 along with the rotation of the adjusting sleeve 50.
