Description

[Detailed description of the invention] This invention relates to a pipe joint device used for a connection part of a fluid pipe, and in particular, one of a pair of plug and socket is supported from a fixed part so as to be slightly displaceable, and the other This pipe joint is designed so that there is no problem even if there is a considerable axial center error when the pipe is moved in the axial direction and connected to the pipe.

Generally, in factory work processes, air or liquid pipes are sometimes connected and disconnected at joints, but connecting and disconnecting these fluid pipes is surprisingly time-consuming and labor-intensive when the pipe diameter is large. This is a job that requires a lot of effort from the staff. However, in recent years, there has been a trend toward labor saving and automation in factory operations, and there has been a desire for pipe fittings that can be operated without manual labor.

This invention specifically solves this problem with fluid pipe fittings. Therefore, the purpose of this idea is to
The purpose of this invention is to provide a pipe joint that can be attached and detached by simply pushing or pulling out either the plug or the socket in the axial direction, and the purpose of this invention is to provide a pipe joint that does not cause any problem even if there is considerable eccentricity during connection. In addition, the purpose of this invention is to provide a pipe joint that can be operated remotely without manual effort, and the purpose of this invention is to provide a pipe joint that can save labor and automate factory work. It is on offer.

That is, this invention provides a pipe joint device in which a plug 1 and a socket 2 can be connected and disconnected as a pair, as in the illustrated embodiment, in which the plug 1 and the socket 2 are arranged in the vertical direction. At least one of the plug 1 and the socket 2 has a male and female structure, one of which is a protruding part and the other is a conical funnel part that guides it.
It is surrounded by a frame 21 with a margin so that it can move in the axial direction and in the direction crossing the axis, and within this frame 21 is a conical corle spring 23, with its large diameter portion seated on the frame. fixed in a direction that intersects the axial direction,
In addition, the small diameter portion engages with the plug 1 or socket 2 disposed within the frame 21 to urge and press the plug 1 or socket 2 forward in the axial direction while also centripetally holding it in the direction intersecting the axis. The plug 1 or the socket 2 in which the fluid source is arranged has a built-in valve 18 which is energized to close the flow path when the joint is disconnected. The present invention relates to a pipe joint device characterized in that flange portions 9 and 16 are provided facing each other, and wide packings 10 and 17 are disposed on the flange portions 9 and 16 so as to face each other.

An embodiment of this invention will be described with reference to the drawings. In Figures 1 to 4, plug 1 and socket 2
constitutes a pipe joint as a set. The plug main body 4 connected to the pipe 3 has a conical protruding shape, has an insertion pipe 5 at its center, and is fixed by a stopper 7 via a rubber ring 6. As shown in FIG. 3, the insertion tube 5 is provided with holes 8 in the circumferential direction, so that fluid can flow laterally here. A wide rubber packing 10 is attached to the flange portion 9 of the plug body 4.

The socket 2 has a funnel part 11 provided at the front part,
It is made up of a socket body 12 and a stopper pipe 13 joined in sequence, connected to a flexible hose 14, and tightened with a band 15. The funnel portion 11 widens conically and has a flange portion 16 thereof.
A wide rubber gasket 17 is attached to the .
A valve 18 is built inside the socket body 12,
The valve 18 is closed to the rubber ring 2 by the force of the coil spring 19.
0 serves as a valve seat and is in contact with this to close the flow path. These flange portions 9, 10 and wide packings 10, 17 allow the plug 1 and the socket 2 to be firmly attached even if they are eccentric.

A box-shaped frame 21 is provided around the stopper pipe 13 with a gap therebetween. Frame body 21
has a short cylindrical shape, and is assembled into two halves as shown in FIG. 5, and is attached to a fixed part by its flange part 22. A conical coil spring 23 is interposed between the frame body 21 and the stopper pipe 13 so as to wind the stopper pipe 13. Then,
This conical coil spring 23 has a large diameter portion seated in the frame body 21 and fixed in a direction intersecting the axial direction, and a small diameter portion thereof is a socket disposed within the frame body 21. 2 and the socket 2
It is arranged so that it is biased forward in the axial direction and held centripetally in the direction intersecting the axis.

To connect the plug 1 to the socket 2, which is supported from the fixed part, it is simply necessary to advance the plug 1 in the axial direction. At this time, even if there is an eccentricity error between the mutual axes, the plug 1 is guided by the funnel part 11 of the socket 2 and moves toward connection. The socket 2 moves eccentrically in the direction intersecting the axis without tilting its axis due to the action of the coil spring 23, thereby ensuring the connection with the plug 1.

At this time, if the eccentricity described above is large, the entire socket 2 is connected to the hose 14, so the stopper pipe 13 resists the spring 23 and moves toward the frame 21.
can be displaced until it hits ±
Even if there is a large eccentricity of 5 mm or less, it can be connected without any problem. Finally, the rubber packings 10, 17 attached to the flanges 9, 16 of the plug 1 and socket 2, respectively, come into close contact to maintain airtightness. When connected, the insertion tube 5 hits the valve 18 inside and pushes it open against the spring 19. Since the insertion tube 5 has a circumferential hole 8, a flow path is communicated therewith. At this time, a rubber ring 6 is placed behind the insertion tube 5.
It acts as a buffer.

When the plug 1 is pulled out from the socket 2, the main body of the socket 2 returns to its original position as shown in FIG. 2 by the force of the spring 23, and the valve 18 closes the flow path by the force of the spring 19. In this disconnected state, as described above, the conical coil spring 23 is inside the frame 21.
The large diameter portion is seated on the frame body and fixed in a direction intersecting the axial direction, and the small diameter portion engages with the socket 2 disposed within the frame body 21 to move it forward in the axial direction. Since the socket 2 is placed so that it is centripetal in the direction crossing the axis while being biased and pressed, the socket 2 is always centripetal with respect to the frame 21, and when the socket is next connected, The position will not go out of order, and therefore, if the frame body 21 is firmly fixed, the plug 1 can be easily placed in a suitable position in the socket 2.

Next, we will discuss an example of applying this invented pipe joint to an ice factory. In the ice cube manufacturing process, compressed air is blown into raw water in an ice can to stir the raw water in order to produce transparent ice. Since the lid of the ice can must be opened and closed and the ice can transported each time it is dehydrated and watered, it is necessary to connect and disconnect the main compressed air supply pipe and branch pipes. Conventionally, this was done manually, but with this idea, the air supply branch pipe is supported on the surface of the ice can lid, and
This is extremely advantageous because the air supply branch pipe and the main pipe can be automatically disconnected and connected at the same time by opening and closing the lid.

As explained above, according to this invention, it is sufficient to connect or disconnect the fluid pipe joint by simply advancing or retracting either the plug or the socket in the axial direction, and the eccentricity error of the axis is quite large during the connection. You can easily connect them even if you use them. This simplifies the operation of the fluid pipe joint, thereby enabling unmanned remote control.

Although the above description has been made with reference to the illustrated embodiment, it is also possible to manufacture a plug and socket with the same partial structure reversed to achieve the same effect.
