Abstract

(57) [Abstract] [Purpose] The present invention relates to a pipe joint. The joint of the present invention comprises a main body having two cavities and a member having a portion for connecting pipes rotatably incorporated in the cavities.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a joint for connecting pipes such as water pipes, gas pipes, and other transportation pipes.

[0002]

[Prior art]

 Conventional pipe joints such as gas pipes and water pipes are connected in a straight line or at a right angle, so the place to lay them is limited, or when force is applied from the outside such as an earthquake, force is applied to the joint part. The damage was concentrated and the joint part was remarkable. Also, in the conventional joint, when the product to be delivered flows through the pipe, the direction and speed of the flow at the joint can be changed, which causes vibration to concentrate on the joint and cause noise. Sometimes the joint part came off due to water pressure or vibration.

[0003]

[Problems to be solved by the device]

 Conventional pipe joints such as water pipes and gas pipes are mainly straight or right-angled. Therefore, when laying the pipes, it was not possible to freely control the pipes and the pipes were wasted, and the construction period was lengthened due to the construction of the unnecessary portions. Also, when vibration or force is applied to the pipe, the vibration or force concentrates on the joint, and the joint may come off. On the other hand, since pipe joints are used in large quantities, if they are difficult to manufacture and assemble, they will not be actually used in terms of cost and labor.

[0004]

[Means for Solving the Problems]

 The structure is as follows. (A) The main body is composed of two parts 1 and 2, and when combined, there are two cavities 3 and 4, which are substantially spherical inside, and they are connected. (B) Into the cavities 3 and 4, members for connecting hollow pipes 3'and 4'having substantially spherical bodies are incorporated. (C) There is a packing 7 on the outside of the member for connecting the hollow pipes 3'and 4'which are substantially spherical. (D) The main bodies 1 and 2 are provided with the tongue-shaped member 6 at least at one end of the cavity.

[0005]

[Action]

 A pipe is attached to the part of the two roughly spherical bodies that are built into the main body that is divided into two parts, and the liquid or gas is delivered.

[0006]

【Example】

 Embodiments of the present invention will be described below. The joint of the present invention is composed of two substantially spherical cavities 3 and 4 in a body which is divided into 1 and 2 and hollow members 3'and 4'having a substantially spherical shape for connecting pipes. Some means for fixing the packing 7 is provided on the outer surface of the member connecting the substantially spherical pipes 3'and 4'in the cavity, and the packing 7 is fitted therein. This prevents the substances delivered in the pipe 5 from leaking from the gap between the substantially spherical members connecting the cavities 3 and 4 of the main body and the pipes 3'and 4 '. The tongue-shaped member of 6 provided on at least one side of the two cavities 3, 4 of the main body is 3'or 4'when one delivered from a substantially spherical member connecting one pipe of 3'or 4 '. Before flowing into the other spherical member that connects the other 4's pipe, stop the flow once to prevent it from flowing between the main body cavity and the substantially spherical member that connects the pipes. Two pipes, 3'and 4 ', are attached to the outside of the main body of the substantially spherical body to attach the pipe 5 to deliver the liquid or gas. The material of the joint body may be concrete, metal, resin, ceramics, or the like. Concrete materials, metals, resins, ceramics, etc. can be considered as the material for the members that connect the substantially spherical pipes.

[0007]

[Effect of device]

 (1) Since the main body is divided into multiple parts, it is possible to assemble by simply inserting the substantially spherical member that connects the pipes into the main body and then fixing the divided parts of the main body, for example, by screwing, so the manufacturing cost is low, Further, the work of assembling the joint becomes easy. (2) Since the pipes can move freely inside the body, the angle between the pipes attached to both ends of the joint can be changed. (3) When laying pipes, the degree of freedom in handling the pipes is great. (4) When laying in the soil, laying a row of pipes using the spherical joint of the present invention for passing an earthquake or a car by making the angles of the pipes obtuse by sandwiching the joint beforehand. Even if the land is deformed, the pipe line including the joint is prevented from coming off the spherical joint by receiving vibration or force from the outside and changing the angle of the joint to expand or contract the entire pipe. (5) Since the joint body is made of concrete, resonance of the pipe can be prevented and noise can be prevented or reduced when the pipe flows through the pipe. (6) Since the outer diameter of the member that connects the substantially spherical pipes is sufficiently larger than the diameter of the openings at both ends of the cavity of the substantially spherical body of the joint body, a member that connects the substantially spherical pipes from the joint body due to water pressure or vibration. There is no worry that it will come off.
