2. Description of the Related Art A slide valve provided in a pipeline and used for opening and closing the pipeline generally has a structure as shown in FIGS. That is, the valve body 1 of the conventional slide valve is composed of two parts, a fully open part 1A having the valve hole 1a formed therein and a fully closed part 1B having no valve hole 1a formed therein. 1C is slidably fitted to the guide portions 4 and 4 on the side of the valve box 2 and the bonnets 3 and 3 connected to the valve box 2 to be stored in the valve box 2 and the bonnets 3 and 3, and through the valve rod 5. It is connected to a reciprocating mechanism (not shown). Therefore, the valve body 1 opens the pipeline 6 by sliding it to the fully open position shown in FIG. 5 by the operation of the reciprocating mechanism, and shuts off the pipeline 6 by sliding it to the fully closed position shown in FIG. Will be done. However, with conventional slide valves,
Since the valve body 1 is composed of two parts, the fully open part 1A and the fully closed part 1B, the dimension in the sliding direction of the valve body 1 becomes long, and the large bonnets 3 for storing the long valve body 1 are formed. You will need it. Therefore, there is a problem that the slide valve becomes large and heavy.

DISCLOSURE OF THE INVENTION According to the present invention, in a slide valve in which both widthwise ends of a valve body are slidably fitted in guide portions on the valve box side, the valve body is constituted only by a fully closed portion. In addition, a seal member made of an elastic plate material, which extends in the width direction of the valve body and has both ends fitted to the guide portions, is attached to the tip end of the valve body. The size of the bonnet is reduced by reducing the size of the slide valve and the size of the slide valve is reduced to achieve the purpose of reducing the weight.

According to the present invention, since the valve body is constituted only by the fully closed portion, the dimension of the valve body in the sliding direction is shortened. Further, when the valve body is slid to the fully open position, the seal member made of the elastic plate member is reversed to the bonnet side and is interposed between the valve box and the bonnet, and the valve box and the bonnet move in the moving space of the valve body and the guide. The seal state is secured so that they do not communicate with each other through the section.

With such a structure, the pipe 6 is shut off by sliding the valve body 1 to the fully closed position shown in FIG. 1 by operating a reciprocating mechanism (not shown). in this case,
As shown in FIG. 2, the seal member 7 is pushed down by the valve body 1 to form a semicircular groove 1 formed on the inner surface of the lower portion of the valve box 2.
Fit to 0. The valve body 1 is operated by the operation of the reciprocating mechanism.
3 is slid toward the fully open position, at the intermediate opening position shown in FIG. 3, the central portion in the width direction of the seal member 7 and the vicinity thereof are in an inverted initial posture in which they protrude in a mountain shape. By sliding from the position to the fully open position, the state shown in FIG. 4, that is, the seal member 7 is inverted to the bonnet 3 side and interposed between the valve box 2 and the bonnet 3, and the valve box 2 and the bonnet are inserted. 3 secures a seal state in which the valve 3 does not communicate with each other through the moving space of the valve body 1 and the guide portions 4 and 4, and prevents the fluid flowing through the pipe line 6 from leaking to the bonnet 3 side. When the valve body 1 in the fully open position is slid toward the fully closed position, the seal member 7 returns to the state of FIG. 1 by the reverse operation of the above operation.

As described above, since the valve body 1 is constituted only by the fully closed portion 1B, the dimension of the valve body 1 in the sliding direction is shortened, and the bonnet 3 for storing the valve body 1 is connected to one side of the valve box 2. It is sufficient to connect only to the side. Therefore, since the bonnet 3 is reduced, the slide valve can be downsized and its weight can be reduced. Further, when the valve body 1 is slid to the fully open position, the seal member 7 is reversed to the bonnet 3 side and interposed between the valve box 2 and the bonnet 3, and the valve box 2 and the bonnet 3 are connected to the valve body 1. Since the seal state in which the valve body 1 and the guide portions 4 and 4 do not communicate with each other is ensured, it is possible to reliably prevent the fluid from leaking when the valve body 1 is fully opened.

As described above, according to the present invention, since the valve body is constituted only by the fully closed portion, the dimension of the valve body in the sliding direction is shortened, and the bonnet for storing the valve body is used in the valve box. Only one side should be connected. Therefore, since the bonnet is reduced, the slide valve can be downsized and the weight thereof can be reduced. Further, when the valve body is slid to the fully open position, the seal member made of the elastic plate member is reversed to the bonnet side and is interposed between the valve box and the bonnet, and the valve box and the bonnet move in the moving space of the valve body and the guide. It is possible to securely prevent the fluid from leaking when the valve body is fully opened by ensuring a seal state in which the valve body does not communicate with each other.
