Abstract

PROBLEM TO BE SOLVED: To connect a joint without disassembling it, and to provide excellent sealing performance by cutting the end part of a polyethylene tube at a right angle to a shaft, and connecting them in a single operation by pushing the cutting end in the opening part of the joint without applying chamfering as it is. SOLUTION: A metallic joint 10 is composed of a constitutive member in the almost same as a conventional joint, and is composed of a main body 11, a box nut 12, a slipping-out preventive split ring 13, a backup washer 14 and tapered cylindrical packing 15. However, a point different from the conventional joint in the joint 10 is that the constitutive member is an integrally assembled assembly and the constitutive member is not disassembled when connecting a polyethylene tube. The polyethylene tube 20 is pushed in an opening of the joint 10 in the arrow 21 direction without applying any chamfering to the end part of the tube, and the connection is completed only by fastening the box nut 12 so as to secure sealing performance.

2. Description of the Related Art There are six types of polyethylene pipes for water supply used as water supply pipes, each having a nominal diameter of 13 mm to 50 mm.
There is a seed tube. The type 1 pipe and the type 2 pipe have the same outer diameter and different inner diameters, and therefore have different wall thicknesses. Conventionally, a polyethylene pipe joint is provided with a thin-walled core pipe that fits into the inner surface of the polyethylene pipe in the main body. Were externally fitted, these were fastened with cap nuts, and the polyethylene tube meat was crimped between the core tube and the packing. There has been a device to reduce the number of parts by integrating the forward / reverse conical taper packing and split ring into an abacus ball-shaped plastic product and making a cut in the axial direction (Japanese Patent Publication No. 54-41252). No.). In a pipe joint having such a core pipe, it is necessary to prepare two different kinds of joints, one for a type 1 pipe and the other for a type 2 pipe, having different wall thicknesses for a polyethylene pipe having the same nominal diameter.
On the other hand, the core tube was eliminated, the packing shape and the cap nut were improved, and the packing and split ring were pressed by the conical taper surface of the inner surface of the main body and the inner conical taper surface of the cap nut to reduce the diameter of the inner ring of the main body. There is an improved pipe joint which is pressed against a conical taper surface and an outer peripheral surface of a polyethylene pipe so as to maintain a sealing property.

In this case, the inner diameters of the packing 65 and the split ring 63 are made smaller than the outer diameter of the polyethylene pipe from the viewpoint of sealing properties and prevention of falling out. In order to fit these into the polyethylene pipe, it is necessary to bevel the pipe end of the polyethylene pipe 20 in advance. Therefore, the polyethylene pipe cannot be inserted into the joint and joined by one-touch. As shown in FIG. 5, the cap nut 62, the split ring 63 for retaining, the ring-shaped washer 64, and the rubber packing 65 are connected to the outer circumference of the polyethylene pipe. It is necessary to screw the cap nut 62 into the main body 61 in advance.

[0006] The apparatus of the present invention which can preferably carry out the above method comprises a main body, a tapered cylindrical packing,
Backup washer, escape prevention split ring,
The inner part of the tapered cylindrical packing is formed slightly larger than the outer diameter of the polyethylene pipe, and the inner circumferential ridge of the escape prevention split ring is one in the opposite direction. A joint for a polyethylene pipe, wherein the joint has a sawtooth cross section that has been tilted by 10 degrees. This joint is a metal joint.

The escape prevention split ring is provided with a slit-shaped split on a part of the circumference and a conical taper on the outer circumference. When a polyethylene pipe is inserted, its inner diameter is set to be substantially equal to the outer diameter of the polyethylene pipe to facilitate insertion. By tightening the outer periphery with the cap nut, the inner circumferential ridge of the sawtooth cross section formed on the inner surface cuts into the outer periphery of the polyethylene tube and prevents the polyethylene tube from coming off. The present invention is characterized in that the sawtooth cross section of the inner circumferential ridge is slightly inclined in the counter-pull-out direction. This fall is 1 to 10 degrees. 1
If the degree is less than 10 degrees, the effect of smooth insertion of the polyethylene tube and the effective prevention of slipping out is insufficient, and if it exceeds 10 degrees, the effect does not increase.

It is considered that the smooth insertion of the escape prevention split ring and the effect of preventing the escape ring are caused by the following reasons. That is, when cutting the escape prevention ring, if a surface perpendicular to the ring axis of the inner circumferential protrusion having a serrated cross section is formed on a surface slightly inclined in the anti-escape direction,
A burr is formed at the same angle as the face lying on the top of the sawtooth section.
The inventor has found that this fallen burr is effective in smoothly inserting the polyethylene tube and effectively preventing the tube from coming out. This burr can be effectively formed by forming the burr so as to slightly fall in a direction opposite to the direction in which the burr is substantially perpendicular to the ring axis. The range of the falling angle is 1 to 10 degrees. A more preferred range is 1 to 5 degrees. Most preferably, it is 1 to 2 degrees.
