Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water distribution pipe faucet used when a buried water pipe is connected to water supply equipment in each household.

Conventional water distribution pipe faucets have a structure in which a fixed type plug member is attached to a buried water pipe, and there is a problem in that they cannot absorb vibrations caused by an earthquake or the like.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a water distribution faucet for piping that is capable of absorbing biaxial vibrations even in the event of an earthquake.

In order to achieve this object, the present invention is designed to connect an upright cylinder part that is vertically connected to a water distribution pipe and has a horizontal opening, and a water supply pipe installation port that is horizontally connected to a water supply pipe to be sealed in the pipe axis direction. a horizontal cylindrical part that is movably fitted inward; an external fitting part that is externally fitted to the rising cylindrical part is provided at the base end of the horizontal cylindrical part, and the external fitting part is sealed around the axis of the rising cylindrical part; The water pipes are slidably and rotatably fitted so that the water distribution pipe and the water supply pipe communicate with each other.

An example of implementation will be described below based on the drawings.

In FIG. 1, reference numeral 1 denotes a water pipe, and normally when a water distribution pipe 2 is attached to the water pipe 1, it is installed via a saddle 3.

That is, the saddle 3 holds the water pipe 1 from above and below with an upper saddle 4 that covers the upper half circumferential surface 1a of the water pipe 1 and a lower saddle 5 that covers the lower half circumferential surface 1b of the water pipe 1, and bolts 6 are attached to the opposing edges of each.
Tightening is for fixing.

I is a mounting part of the water distribution faucet 2 provided on the saddle 3, and the mounting part 7 is provided at the upper position of the saddle 3 because the water distribution faucet 2 is installed after the water distribution pipe 1 is buried. There is.

FIG. 2 shows the detailed structure of the water distribution faucet 2. As shown in FIG.

In the figure, 8 has a threaded part 9 at the lower end that is screwed into the mounting part 7 of the water distribution faucet 2, and a threaded part 11 at the upper end to which the blind cover 10 is attached.
It is a rising cylindrical portion having.

The rising tube section 8 is attached to the water pipe 1 in a vertical position, and has a valve body 14 with an operating shaft 13 projecting to the outside at an upper position near the attachment end 12. A predetermined number of horizontal openings 15 are formed in the cylinder wall at equal intervals in the circumferential direction.

Further, the lateral opening 15 is communicated with by an annular groove 16 carved in the cylinder wall.

The cylindrical wall near the annular groove 16 is formed into a sliding surface 17, and a step portion 18 is formed at the bottom of the sliding surface 17.

Note that 19 is a water distribution hole of the valve body 14, and 20 is a water distribution hole for pressing the valve body 14 through a packing 21 and for opening the operating shaft 13.
This is a lid body supported via a ring 22 so as to be slidable and rotatable in a hermetically sealed manner.

Next, 23 is a horizontal cylindrical portion arranged in the horizontal direction.

The horizontal cylindrical portion 23 is capable of sealingly sliding in the pipe axial direction via an O-ring 25 through a water supply pipe attachment port 24 that is horizontally connected to a water supply pipe (not shown) connected to the water supply equipment of each home. It has an external fitting part 26 which is fitted inside and externally fitted onto the sliding surface 17 of the rising cylinder part 8 at its base end.

The lower end of the outer fitting part 26 is locked to the stepped part 18 of the rising tube part 8, and the upper end is positionally regulated by a press ring 27, and a pair of upper and lower O-rings are arranged on the sliding surface 17. 28°29, the horizontal cylindrical portion 23 is connected to the rising cylindrical portion 8.
Enables closed sliding rotation around the axis.

Further, the water supply pipe attachment port 24 has a protrusion 32 that can be engaged with both the stepped portion 30 of the horizontal cylindrical portion 23 and the cap nut 31 to prevent removal.

33 is a communicating hole. When the water distribution faucet 2 having such a configuration is attached to the water pipe 1 with the rising cylinder part 8 in a vertical position and the water supply pipe attachment port 24 is connected to the water supply pipe, the relative horizontal vibration between the water pipe 1 and the water supply pipe is caused by the horizontal vibration of the horizontal cylinder part. 23 and the water supply pipe attachment port 24 in the tube axis direction, and the relative rotational vibration in the horizontal direction can be absorbed by the rotation mechanism of the upright cylinder part 8 and the horizontal cylinder part 23.

As described above, the present invention can absorb the vibrations A and B in directions perpendicular to each other as shown in FIG. 3, and is therefore extremely useful as a water faucet whose damage is expensive and difficult to repair.
