Background
Ball valves (ball valve) come out in 50 s of the 20 th century, and with the rapid development of ball valve science and technology, the continuous improvement of production process and product structure has rapidly developed into a main valve class. The use of ball valves is increasing year by year in countries with industrially developed western industries.
In China, the ball valve is widely applied to industries such as petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, steel and the like, and plays a significant role in national economy.
The ball valve has the action of rotating 90 degrees, and the cock body is a sphere and is provided with a circular through hole or a channel passing through the axis of the sphere. The ball valve is mainly used for cutting off, distributing and changing the flow direction of a medium in a pipeline, and can be closed tightly only by rotating 90 degrees and a small rotating moment. The ball valve is most suitable for being used as a switch and a stop valve.
However, the existing ball valve has more single valve function and no feedback function, and is not very beneficial to the production requirement of the whole control system.

In order to solve the technical problem, the utility model provides a take feedback function ball valve.
In order to solve the technical problem, the utility model discloses take following technical scheme:
the utility model provides a take feedback function ball valve, includes the ball valve, has the valve rod in the ball valve, the top of valve rod extends the top of ball valve, and the top fixed mounting of valve rod has the handle, and the support is installed at the ball valve top, installs limit switch on the support, and limit switch has the feedback pole, and the erection joint has the switching pole on the handle, switching pole and feedback pole erection joint, and drive switching pole, feedback pole, valve rod synchronous rotation when the handle rotates.
The top end of the valve rod is provided with a threaded hole, the lower part of the switching rod is provided with matched external threads, the lower part of the switching rod penetrates through the threaded hole inserted into the valve rod from the handle to be screwed and locked, and the upper end of the switching rod is fixedly connected with the feedback rod.
The lower part of the switching rod is sleeved with an elastic washer and a locking nut, the elastic washer is tightly pressed on the handle, and the locking nut is tightly pressed on the spring washer.
The upper portion of switching pole is equipped with the draw-in groove, and the feedback rod cartridge is gone into in the draw-in groove and is locked.
The support is a transversely placed U-shaped structure, the open end faces horizontally, and the handle extends out along the open end of the support.
And the limit switch is connected with the bracket in a locking way through a bolt.
The utility model discloses when realizing the valve function, have the feedback of valve state, simple to operate need not occupy more space.
