Fig. 1 is a schematic view of the cross-sectional structure of the valve body of the present invention.

In the figure: 1. a valve stem; 2. a valve core; 3. a valve port; 4. a valve body; 5. a filler; 6. a nut seat; 7. inputting into a bin; 8. an output bin; 9. a notch; 10. a handwheel.

Detailed Description

As shown in figure 1, a novel straight-through control valve comprises a valve rod 1, a valve core 2, a valve port 3, a valve body 4 and a filler 5, wherein the valve rod 1 is arranged in the valve body 4, the valve core 2 is arranged on the valve rod 1, the filler 5 is arranged above the valve body 4, a nut seat 6 is arranged on the valve body 4 above the filler 5, the lower end of the valve rod 1 is arranged in the valve body 4 after passing through the filler 5, the interior of the valve body 4 is divided into an input bin 7 and an output bin 8, the valve port 3 is arranged on the valve body 4 at the joint of the input bin 7 and the output bin 8, the valve port 3 is engaged with the valve core 2 of the valve rod 1, the end part of the valve port 3 is arranged in an arc shape, the valve core 2 is arranged in a conical shape, the valve core 2 is engaged with the valve port 3 after descending, the valve rod 1 is provided with threads, the valve rod 1 is connected with the nut seat 6, the top of the valve rod 1 is provided with a hand wheel 10.

In actual work, a valve rod 1 is connected with a nut seat 6 in a valve body 4 in a threaded manner, the valve rod 1 rotates through a hand wheel 10 at the top, after the hand wheel 10 is rotated, so that the valve rod 1 descends in the valve body 4, the valve core 2 on the valve rod 1 descends and then is fit with the valve port 3 in the valve body 4, and the bottom of the valve rod 1 is inserted into the notch 9, so that the position of the valve rod 1 can be limited, the deviation can be prevented, when the valve needs to be opened, the hand wheel 10 is rotated reversely to rotate the valve rod 1 out of the nut seat 6, the valve rod 1 is always in the gap 9 of the valve body 4 to prevent the valve rod 1 from deviating and influencing the secondary closing of the valve, an input bin 7 and an output bin 8 are arranged in the valve body 4, liquid enters the valve body 4 through the input bin 7 and enters the output bin 8 through the valve port 3, the filling body 5 above the valve body 4 can effectively prevent the liquid from overflowing from the valve body 4 when the valve body 4 is conveyed out through the output bin 8.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
