Description

A pipe connection device for connecting stainless steel pipes

technical field

The utility model relates to a stainless steel pipe joint, in particular to a pipe connection device for connecting stainless steel pipes.

Background technique

In modern life water supply and drainage and direct drinking water pipeline systems, stainless steel pipe fittings are the most widely used pipe fittings. Because the metallographic structure of stainless steel is very stable and corrosion-resistant, it is widely used in water transportation, oil transportation pipelines and various liquid chemical materials. Conveyor pipeline, its installation methods mainly include argon arc welding type and compression type. Since argon arc welding requires high welding technology, long-term professional training is required for the factory, and the relative cost is relatively high. High pressure is required, and when fittings of different specifications are installed, different crimping jaws are required, which is relatively troublesome to replace. How to design a pipe connection device that is easy to install, high in installation efficiency, and stable and reliable in connection is a problem that needs to be solved.

Utility model content

In order to solve the technical problems such as inconvenient connection, high cost, difficult installation, and troublesome disassembly and replacement of the existing pipe joints, the utility model provides a pipe connection device for connecting stainless steel pipes to achieve simple structure, convenient installation, and High efficiency, stable and reliable connection, easy replacement and disassembly.

The technical scheme adopted by the utility model to solve the above technical problems is: a pipe connection device for connecting stainless steel pipes, including a pipe joint, a pipe joint assembly and a pipe connection structure, the pipe joint assembly consists of a sealing ring installation groove and a sealing ring The pipe connection structure is composed of threaded holes, screws and the fixing part of the outer wall of the pipe joint. The pipe joint is provided with a pipe socket, and at least one seal ring installation groove is arranged in the pipe socket, and the seal ring installation groove is provided with A sealing ring; a step for axially positioning the pipeline is arranged in the pipe socket; there are threaded holes and screws for fixing the stainless steel pipe on the outside of the pipe joint, and the threaded holes are located outside the installation groove of the sealing ring.

The number of the sealing ring installation grooves is 6.

The screws are hexagon socket head screws.

The number of said threaded holes is 2 to 8, distributed on the outside of the pipe joint.

Compared with the prior art, the beneficial effect of the utility model is that: the utility model has at least one or more threaded holes for fastening the pipe body on the outside of the pipe joint, and the stainless steel pipe is inserted into the inside of the pipe joint, and is fixedly connected by external threads , Abandoning the traditional argon arc welding and clamping installation methods, the installation and disassembly are more convenient and simple, without high technical requirements and expensive installation tools, ordinary workers can construct smoothly after simple training; pipe joints can be used repeatedly for many times Second, it is not easy to be damaged, can be recycled and reused, and saves resources; the pipe joint assembly of the utility model is composed of a sealing ring installation groove and a sealing ring, and the sealing ring ensures that the pipeline is firmly connected and has excellent sealing performance.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

As shown in the figure, a pipe connection device for connecting stainless steel pipes includes a pipe joint 1, a pipe joint assembly and a pipe connection structure. The pipe joint assembly is composed of a sealing ring installation groove 3 and a sealing ring 4. The hole 5, the screw and the fixing part of the outer wall of the pipe joint 1 are formed. The pipe joint 1 is provided with a pipe socket 2, and the pipe socket 2 is provided with at least one seal ring installation groove 3, and the seal ring installation groove 3 There is a sealing ring 4 inside; the pipe socket 2 is provided with a step for axial positioning of the pipe; there are threaded holes 5 and screws for fixing stainless steel pipes on the outside of the pipe joint 1, and the threaded holes are located in the sealing ring installation groove 3 outside.

The above is the basic implementation mode of the present utility model, further improvements, perfections and limitations can be made on the basis of the above: the number of sealing ring installation grooves 3 as described is 6.

The above is the basic implementation of the utility model, further improvement, perfection and limitation can be made on the basis of the above: the screw as described is a hexagon socket head screw.

The above is the basic implementation of the present utility model, further improvements, improvements and limitations can be made on the basis of the above: as mentioned, the number of threaded holes 5 is 2 to 8, and they are distributed outside the pipe joint 1 .

When working normally, insert the connecting end of the stainless steel pipe into the pipe socket 2, and closely cooperate with the seal ring 4 placed in the seal ring installation groove 3, and the pipe socket 2 is provided for the axial positioning of the pipe. The steps can ensure the axial positioning of the pipe and prevent deflection and other phenomena; the positioning part, that is, the hexagon socket head screw is screwed in through the threaded hole 5 to generate tension, so that the fixed part of the pipe joint 1 is closely matched with the stainless steel pipe, that is, Tight connection of pipes can be realized.

The utility model has the advantages of simple structure, convenient installation, high installation efficiency, stable and reliable connection, easy replacement and disassembly, and solves the technical problems such as inconvenient connection, high cost, difficult installation, troublesome disassembly and replacement of the existing pipeline connectors, and has a great improvement on the prior art.
