It is an enlarged cross section.

1 to 4, the large gate valve 60 is easy to operate the handle of the present invention is formed in a large size is installed in the opening and closing of the fluid transported at a large flow rate, the installation position is not underground As a gate valve 60 is installed in a position that is difficult and inconvenient for the user to hold the handle (handle, lever, etc.), the user can easily and easily operate the body 10, the disk 30, the screw 20 ) And the yoke portion 40 and the handle portion 50.

As shown in Figure 1 and 2, the body 10, the flange 11 is formed on the inlet and outlet side to be installed between the conduit and the conduit is coupled with the other fluid transfer pipe, the stop of the body 10 The settled part 12 which has a hollow part is formed in the upper side. The settled portion is a space in which the disk 30 moved upward in order to communicate with the tubular body is settled, the length protruding upward from the pipeline of the body 10 is formed at least larger than the height of the disk 30 to When opening the tubular body, it is preferable that the flow of the fluid is not disturbed by the disk 30.

Here, the disk 30 is placed inside the body 10 is to be moved up and down by the screw 20 connected to the upper side to interrupt or open the tubular body. That is, the disk 30 is moved downward by the screw 20 to block the flow path of the tubular body, and the fluid is interrupted. On the contrary, the disk 30 is moved upward and positioned in the settled portion 12 to flow the fluid. In addition, the upper end of the settled portion 12 is opened so that the screw 20 can be mounted.

The screw 20 is connected to the upper surface of the disk 30 by a fitting device (not shown), a screw thread is formed on the outer periphery of the screw 20 to rotate the screw ( 20 is driven to drive the disk 30 up and down, and the end of the screw 20 is formed to protrude upward through the upper surface of the body 10, that is, the upper surface of the settled portion 12.

5 to 7, the disk 30 is usually formed of a circular plate body having a predetermined thickness, so that the outer peripheral surface of the disk 30 close to the pipeline of the body when closed. Therefore, the disk 30 is formed with guide grooves (not shown) on both sides of the body 10 in contact with the outer circumferential surface of the disk 30 to prevent being pushed out by the hydraulic pressure, the disk 30 corresponding to the guide groove The guide base 31 is formed on the outer circumferential surface of the) to prevent the guide base 31 from being pushed by the hydraulic pressure by being inserted into the guide groove to slide up and down.

In this structure, the disk 30 is formed of a synthetic resin having a material having a constant elastic outer surface to improve watertightness. The synthetic resin generates wear faster than a metal material, so that the guide 31 is guided. As the groove moves up and down in the groove, wear of the guide guide is rapidly generated.

Therefore, the watertight cap 32 is detachably mounted to the guide stand, which is the portion where the wear occurs, thereby facilitating replacement by wear, and reducing the maintenance cost.

The watertight cap 32 is preferably formed in a size that can cover the front surface of the guide base 31 sliding in contact with the guide groove, reducing the thickness of the guide base 31 by the thickness of the watertight cap 32 Can be installed. Various methods may be used as the mounting means, and typically, a coupling method using protrusions and grooves may be applied.

That is, as shown in Figure 6, the end of the water-tight cap 32 is formed with a coupling protrusion 321 and the corresponding guide base 31 to form a coupling groove 311 to the coupling of the coupling projection and the coupling groove. It can be attached by. In addition, the shape of the coupling protrusion 321 may be protruded to form a round as a whole, or may form a stepped at a right angle or an acute angle.

In addition, as shown in FIG. 7, the coupling groove 311 may be formed in the watertight cap 32, and the coupling base 321 may be formed in the guide base 31 to allow the watertight cap to be mounted. will be.

As shown in FIG. 1, the yoke portion 40 is fixed to the upper surface of the settled portion 12 of the body 10 so that the end portion of the yoke portion 40 supports the screw 20 driven up and down. Is connected to the outer periphery of the, the yoke portion 40 serves to protect the screw 20 so that the screw 20 is formed through the inside of the yoke portion 40 so as not to be affected by the outside.

As shown in FIGS. 1 to 4, the handle part 50 includes a sleeve 51, a handle wheel 52, and a handle to rotate the screw 20 to drive the disk 30 up and down. It consists of a portion 53 and the support 54, the sleeve 51 is installed between the yoke portion 40 and the screw 20 to rotate the screw 20 by rotation to drive up and down .

Here, the sleeve 51 is driven up and down in the same manner as the screw 20 when rotating, the sleeve 51 should not be driven up and down. In order to do so, the sleeve 51 is formed in a cross-sectional " ㅗ " shape so as to be supported by the yoke portion 40, and the upper side is supported by a support member (not shown).

In addition, the handle wheel 52 is protruded so that one side is connected to the outer periphery of the sleeve 51 to bend obliquely downward, and the handle wheel 52 is radial from the sleeve 51 with reference to FIG. 4. A plurality is formed. As such, since the handle wheel 52 is formed in the downward direction, even if the gate valve 60 is installed at a high position, the handle 53 is provided at a low position so that the user can easily use the handle 50. It can work.

And, the handle portion 53 is formed to be bent horizontally to the end of the handle wheel 52 bent downward, the handle portion 53 is made integrally with the handle wheel 52, the handle portion The sleeve 51 is rotated by the user to rotate the sleeve 51, whereby the screw 20 is driven up and down to operate the disk 30.

In addition, the support 54 is formed by connecting the outer periphery of the plurality of handle wheels 52 so that the bent handle wheel 52 is not damaged by an external force, referring to FIG. ) Can be installed in plurality depending on the size of the handle portion (50).
