Example 1

Embodiment 1 is provided with an opening and closing adjustment handle, and has a configuration that the opening and closing adjustment handle is extended or bent around the hinge member.

1A and 1B show an installation space reduced ball valve assembly according to Embodiment 1 of the present invention, which is shown in front view in FIG. 1A and in side view in FIG. 1B.

As shown in the drawing, the installation space reduction type ball valve assembly 10 has fasteners 12a and 12b made of ring nuts at each end of the adapters 14a and 14b, similarly to the general ball valve assembly. The ball member 16 is located in the flow path between the adapters 14a and 14b. In addition, the body 18 provided in the radial direction of the flow path between the adapters 14a and 14b has a structure in which the stem 20 connected to interlock with the ball member 16 is rotatably inserted. Accordingly, the ball member 16 is also interlocked by the opening / closing rotation of the stem 20, wherein the hole drilled through the ball member 16 coincides with the flow path direction of the ball valve assembly 10. If the flow is made, if the hole in the ball member 16 is rotated in a state away from the flow path is blocked. Since the operation of opening and closing according to the rotation of the ball member 16 is the same as the opening and closing rotation of the ball member of the general ball valve assembly, detailed description thereof will be omitted.

Here, in the present invention, the stem 20 is inserted into the body 18, wherein the upper end of the stem 20 is inserted in a state where a part of the stem 20 is drawn out. And the hinge hole 22 is formed in the horizontal direction at the upper end of the stem 20 withdrawn from the body 18.

Opening and closing handle 24 is connected to the upper end of the stem 20 is interlocked. The opening / closing adjustment handle 24 includes a hinge portion 26 corresponding to both outer surfaces of the stem 20, a connection portion 28 connecting the two hinge portions 26 to each other, and a stem between the hinge portions 26. It is composed of an opening groove 30 in which the lead portion of the 20 can be accommodated.

In addition, the hinge hole 32 of the hinge hole 32 formed in the hinge portion 26 of the opening and closing adjustment handle 24 and the stem 20 is coupled to the hinge member 34 in a penetrating state. Accordingly, the opening and closing adjustment handle 24 is rotated to be bent or extended in the longitudinal and transverse direction with respect to the hinge member 34. Here, the hinge member 34 uses a hinge pin made of a pin shape. (See FIG. 1B)

If the opening and closing adjustment handle 24 can take a structure that can be opened or bent around the hinge member 34 as described above, the opening and closing adjustment handle 24 is occupied by the opening and closing adjustment handle 24 when the opening and closing adjustment handle 24 is bent. Installation space is reduced by the space area (D), and furthermore, space can be utilized as much as the installation space area (D).

For example, when the ball valve assembly 10 according to the present invention is installed in a narrow space, the opening / closing drive can be performed with the opening / closing adjustment handle 24 bent in a horizontal direction, if necessary, so that the space is narrow. It is possible to ensure both the elimination of installation constraints and the quick and easy opening and closing operation of the system.

On the other hand, between the hinge hole 32 and the hinge member 34 of the opening and closing adjustment handle 24 is coupled in a state in which the pressing member 36 is disposed. The pressing member 34 is preferably used O-ring (O-ring) having an elastic force is coupled in a state surrounding the hinge member 34.

When the pressing member 36 is disposed between the opening and closing adjustment handle 24 and the hinge member 34 as described above, the pressing member 36 is an elastic force is applied to the opening and closing adjustment handle 24 and the hinge member 34. The pressing force is applied in a state to form a strong friction force. This frictional force formation prevents the opening and closing adjustment handle 24 from easily bending or unfolding in the transverse direction in the longitudinal arrangement or in the longitudinal direction in the transverse arrangement.

That is, when the user uses the opening / closing control handle 24 to open and close the drive word, it is possible to prevent the drive word from being easily made by the occurrence of interference to be bent or extended.

2A and 2B are plan views of FIG. 1A, in which FIG. 2A shows an on mode, and in FIG. 2B, an off mode is shown.

As shown in the figure, the ball valve assembly 10 according to the present invention is shown to take an on mode in which the open / close adjustment handle 24 is opened in a horizontal state and an off mode in a vertical state. In addition, the angular ranges for the on mode and the off mode are shown to be perpendicular.

As described above, when the opening and closing adjustment handle 24 is rotated to take the on mode and the off mode, the hinge member 34 interlocked with the opening and closing adjustment handle 24 protrudes on one side of the upper surface of the body 18. Opening / closing rotation of the opening / closing adjustment handle 24 is set by coming into contact with the side surfaces S1 and S2 of the stopper 38.

[Example 2]

Embodiment 1 described above is provided with an opening and closing adjustment handle, the opening and closing adjustment handle is to rotate around the hinge pin, Example 2 is to open and close the driving drive with the removal of the opening and closing adjustment handle to further reduce the installation space area It has a structure that can be secured.

3A and 3B show an installation space reduced ball valve assembly according to Embodiment 2 of the present invention, which is shown in front view in FIG. 3A and in plan view in FIG. 3B. 4A and 4B are schematic plan views of the stem and the stopper pin of FIG. 3B, which show an on mode in FIG. 4A and an OFF mode in FIG. 4B.

As shown in the figure, the installation space reduction type ball valve assembly 20 is inserted with the stem 40 accommodated inside the body 18. The stem 40 has an opening and closing adjustment groove 44 is formed in the upper center portion, the outer surface is formed with a long groove 46 along the circumference of the stem 40.

On one side of the body 18, a stopper pin 48 is coupled through to the center of the body 18. One end of the stopper pin 48 facing the stem 40 has a coupling structure that is received into the long groove 46 of the stem 40.

In the ball valve assembly 20 according to the present invention, the opening and closing adjustment groove 44 is shown to take an on mode that is opened when placed horizontally and to take an off mode that is closed when placed vertically.

For reference, a tool suited to the opening and closing adjustment groove 44 is used to rotate the stem 40, and as the tool used here, a “-” shaped screwdriver used to turn a screw is often used. However, the opening and closing adjustment groove 44 is not necessarily limited to the structure of the "-" shape, the groove shape or structure of the opening and closing adjustment groove 44 may be variously changed as necessary.

When the opening and closing adjustment groove 44 is to take the on or off mode as described above, the stem 40 to interlock with the opening and closing adjustment groove 44 is rotated, according to the selected opening and closing mode of the long groove 46 When the stopper pin 48 comes into contact with the inner walls P1 and P2, opening and closing rotation is set.

For example, when the ball valve assembly 20 according to the second embodiment is installed, it is possible to further reduce the installation space area than the ball valve assembly 10 of the first embodiment, which is very advantageous for installation, and particularly, in a narrow space. Easy opening and closing drive can be ensured.
