Abstract

The utility model discloses a novel high-pressure-bearing three-way combined connection pipe. One end of the three-way pipe main body is provided with a trumpet-shaped interface, the three-way pipe joint is made of elastic plastic, and one end of the three-way pipe joint is plugged. It is inserted into the horn-shaped interface of the main body of the tee pipe, and the edge of the outer tee pipe joint of the plug is provided with an integrated outer layer ferrule, the diameter of the outer end opening of the outer layer ferrule is smaller than the inner diameter, and the outer layer ferrule is fitted and sleeved together Outside the flared interface, a compression nut for compressing the outer ferrule is screwed on the upper end of the main body of the tee pipe and the outer periphery of the compression threaded pipe. The utility model is divided into two parts, when the tee pipe is under pressure, the greater the pressure, the more closely the inner side wall of the outer ferrule and the outer side wall of the trumpet-shaped interface are contacted, thereby effectively ensuring the main body of the tee pipe and the tee pipe. The firmness of the joint fixed connection is more secure and reliable.

Description

Novel high-pressure-bearing three-way combined connecting pipe

Technical Field

The utility model relates to the technical field of valves, a novel high pressure-bearing tee bend built-up connection pipe specifically says so.

Background

The pipe joint with three openings is called a three-way pipe. The three-way pipe is widely used in pipe networks for conveying liquid and gas. Because of the different conveying media, the material of three-way pipe divide into: cast iron, cast steel, cast copper, cast aluminum, plastic, glass, and the like. The existing tee joint is generally connected by adopting a rigid structure, such as metal, elastic materials such as plastic and the like cannot be used for bearing high pressure, and plastic materials have great advantages in certain aspects such as corrosion resistance, low cost and the like.

Disclosure of Invention

In order to solve the problem, the utility model aims at providing a novel high pressure-bearing tee bend built-up connection pipe.

In order to achieve the above purpose, the technical scheme of the utility model is that: a novel high-pressure-bearing three-way combined connecting pipe comprises a three-way pipe main body and a three-way pipe joint, wherein one end of the three-way pipe main body is provided with a connector with a horn-shaped cross section, the three-way pipe joint is made of elastic plastics, and one end plug of the three-way pipe joint is inserted into the horn-shaped connector of the three-way pipe main body, the plug is composed of two sections of annular bulges with the diameter of the outer end larger than that of the inner end, the edge of the peripheral three-way pipe joint of the plug is provided with an integrated outer layer cutting sleeve, the diameter of the outer end opening of the outer layer cutting sleeve is smaller than that of the inner side, and the outer layer cutting sleeve is jointed and sleeved outside the trumpet-shaped connector, the outer side wall of the pipe body at the upper end part of the three-way pipe main body is provided with an external thread structure, and a compression threaded pipe with an external thread structure is arranged at the bottom corresponding to the pipe body at the upper end part of the three-way pipe main body, and compression nuts for compressing the outer-layer clamping sleeve are screwed on the pipe body at the upper end part of the three-way pipe main body and the periphery of the compression threaded pipe.

Further, the outer end wall body thickness of outer layer cutting ferrule is greater than inboard.

Furthermore, a circle of rubber sealing ring tightly attached to the horn-shaped interface is embedded in the inner side wall of the outer end opening of the outer-layer cutting sleeve.

The utility model discloses divide two parts, the outer end of outer cutting ferrule is thicker, forms the laminated structure that the cross-section is triangle-shaped at tubaeform interface position, and when the three-way pipe pressure-bearing, pressure is big more, and outer cutting ferrule is equivalent to more toward outer, and under gland nut clamping action, the inside wall that makes outer cutting ferrule on the contrary is inseparabler with tubaeform interface lateral wall contact to three-way pipe main part and three-way pipe head fixed connection's fastness has effectively been guaranteed, safe and reliable more.

Drawings

The present invention will now be further described with reference to the accompanying drawings.

Fig. 1 is a schematic view of the structure of the present invention.

Detailed Description

As shown in figure 1, a novel high-pressure-bearing three-way combined connecting pipe comprises a three-way pipe main body 1 and a three-way pipe joint 2, wherein one end of the three-way pipe main body 1 is provided with a horn-shaped connector 3 with a section, the three-way pipe joint 2 is made of elastic plastics, a plug 4 at one end of the three-way pipe joint 2 is inserted into the horn-shaped connector 3 of the three-way pipe main body 1, the plug 4 is composed of two sections of annular bulges with outer end diameters larger than inner end diameters, an integrated outer-layer cutting sleeve 5 is arranged at the edge of the peripheral three-way pipe joint 2 of the plug 4, the outer-end opening diameter of the outer-layer cutting sleeve 5 is smaller than inner side diameters, the outer-end wall thickness of the outer-layer cutting sleeve 5 is larger than inner sides, the outer-layer cutting sleeve 5 is attached to and sleeved outside the horn-shaped connector 3, a circle of, a compression threaded pipe 6 with an external thread structure is arranged at the bottom corresponding to the pipe body at the upper end part of the three-way pipe main body 1, and compression nuts 7 for compressing the outer-layer clamping sleeve 5 are screwed on the pipe body at the upper end part of the three-way pipe main body 1 and the periphery of the compression threaded pipe 6.
