Generally, a rotary valve is equipped with a device that restricts the rotation of the valve stem so that when the valve stem rotates between the valve open position and the valve closed position, it stops accurately at the valve open position or the valve closed position. ing. Conventionally, such a valve stem rotation regulating device has a structure in which a stopper plate is attached to the valve stem on the outside of the valve body, and a portion for regulating the rotation of the stopper plate is formed in the valve body. Due to space constraints, such conventional external stoppers have to be relatively thin, and there is a risk that they may become deformed due to some external force and become unable to stop at a specified position. There is. In addition, since the stopper plate is provided outside the valve body, foreign matter such as mud, sand, and stones may become clogged between the stopper plate and the valve body, making it impossible to obtain the desired valve stem rotation regulating action. This may interfere with the operation of the valve stem itself.

In order to eliminate these drawbacks of the external stopper mechanism, a built-in stopper mechanism has recently been proposed in which a stopper disk is attached to the valve stem inside the valve and a stopper pin is implanted inside the valve body. However, with this structure, once the valve is assembled,
It is not possible to adjust the stop position of the valve stem from the outside, and the valve must be disassembled when necessary. Further, when the valve is operated, the inside of the valve body may be scraped by the stopper disk provided inside the valve, resulting in damage. Furthermore, in the case of a valve with such a structure, if a gland leak occurs and the gland cap is removed to replace or repair the gland packing, the valve stem itself will fall out, resulting in fluid outflow and, therefore, Repairing a ground leak requires cumbersome work such as stopping the flow of fluid.

Furthermore, the present invention has a type of stopper mechanism built into the valve body, and in order to prevent gland leaks, the gland packing can be freely replaced regardless of whether the flow path provided with this valve is opened or closed. Another object of the present invention is to provide a device that prevents the valve stem from falling out even when the ground cap is removed.

Embodiments of the present invention shown in the drawings will be described below. The first feature of the present invention is that the valve body 1 of the rotary valve
In a device for regulating the rotation of a valve stem 3 so as to correctly stop the rotation of the valve stem 3 for operating a valve element 2 provided therein at a different opening position or a valve closing position,
A stopper drum 4 is integrally formed in the middle of the valve stem 3, stopper receiving surfaces 5, 5 are formed on its circumferential surface, and a chamber 6 for receiving the stopper drum 4 is formed in the upper part of the valve body. A stopper drum 4 is built into the chamber 6, and stopper pins 7, 7 are screwed into the side wall of the valve body on the circumferential surface of the stopper drum 4 so as to protrude from the outside into the chamber 6.
The inner end of this stopper pin is arranged in the valve body 1 at a position where it comes into contact with the stopper receiving surface 5 of the stopper drum 4, and the position of the inner end of this stopper pin can be adjusted from outside the side wall of the valve body. It's what I did. In the figure, 8 indicates a lock nut that fixes the stopper pin in the adjusted position, 9 indicates a first gland packing mounted between the valve stem 3 and the valve body under the stopper drum 4, and 10 indicates a lock nut mounted on the valve body. A removably attached ground cover,
11 shows a second gland packing on which a gland cover and a valve stem are mounted on the stopper drum.

Furthermore, the second feature of the present invention is that in the above device, a stopper drum 4 is integrally formed in the middle of the valve stem 3, and a groove 12 is formed on the circumferential surface of the stopper drum 4. A gland having stopper receiving surfaces 5, 5 formed on its bottom surface, a chamber 6 for receiving the stopper drum 4 formed in the upper part of the valve body, and having a hole above the valve body through which the upper part of the valve stem 3 passes. A cover 10 is detachably attached to close the upper side of the chamber 6, and the stopper drum 4 is built into the chamber 6.
A stopper pin 7 is provided on the side wall of the valve body around the valve body so as to protrude from the outside into the chamber 6, and the inner end of the stopper pin 7 is inserted into the groove 12 on the circumferential surface of the stopper drum 4. The gland packings 11 and 9 are placed between the valve stem 3, the gland cover 10, and the valve body 1 above and below the stopper drum 4. It is because of the placement.

According to this invention, when a ground leak occurs, as shown in FIG. 3, even if the ground cover 10 is removed, the stopper pin 7 is engaged in the concave groove of the stopper drum. The rod 3 will not come off, and by removing the gland cover 10 and replacing the gland packing 11, leaks can be prevented at this portion.

However, in such a structure, if the upper and lower surfaces of the stopper drum 4 are made completely circular and tightly engaged in the chamber 6, there will be no sharp points that could scrape the inner surface of the valve body when the valve stem is rotated. No sharp corners are formed, and the corners of the cutout formed to obtain a stopper function are prevented from scraping the inner surface of the valve body during valve operation, as in the conventional case.
