Description

Joint flange structure improvement

This creation mainly reveals a joint flange, especially an improved joint structure for improving the tightness.

According to the arrangement of the pipeline, various fluid (liquid, gas) transmission paths are provided to increase the convenience, and various telescopic pipe joints connected in the pipeline mainly expand or contract due to temperature changes in the absorption pipeline. In order to avoid the expansion and elongation of the pipeline, the bending or shrinkage becomes shorter and breaks, and the situation of fluid leakage in the pipeline is reduced. For example, if the fluid conveyed by the pipeline is oil, liquefied petroleum gas, toxic chemical fluid, high pressure gas, then the fluid is outside. The leakage condition will cause dangers such as pollution, gas explosion or toxic gas diffusion, so the telescopic pipe joints provided in the pipeline have an important position for the whole pipeline device.

Moreover, the main uses and transmission fluids of various telescopic pipe joints are different. The conventional technical means must be specially made with the telescopic pipe joints, so the price is relatively expensive, difficult to install, and easy to displace or partially when the bolt locking force is uneven. Deformation.

In view of this, how to eliminate the above-mentioned deficiencies is the technical difficulty point that the creators of this case want to solve; however, the creators of this case are based on years of experience in relevant industries, and after many years of painstaking research, trial improvement, finally The successful completion of the case and the creation of this creation to enhance the efficacy.

In view of the above disadvantages, the present invention is designed to improve the joint flange structure, and includes: a sealing member which is an annular body. And a joint flange (Flange), the joint surface is provided with an annular groove, the sealing element is installed in the annular groove, thereby clamping a telescopic pipe joint and locking it in a pipeline The flange is joined to tightly clamp the sealing member to achieve a liquid-tight or airtight effect.

The main purpose of the improvement of the joint flange structure of the present invention is to improve the adhesion between the joint flange and the pipe and the pipeline.

The secondary purpose of the improved joint flange structure is that the sealing element is clamped in the groove of the joint flange so that it is not easily displaced or deformed.

In order to make it easier for your review committee to understand the content of this creation and the functions it can achieve, please refer to the specific examples in the diagram, as detailed below:

First, referring to the first figure, in the first embodiment of the present invention, the inventive joint flange 1 is improved in structure, comprising: a sealing member 10 and a joint flange 20. among them

The sealing member 10 is an annular body. The upper end of the inner ring of the sealing member 10 is formed with a flange 11 inwardly. The flange 11 is an annular body.

The joint flange 20 has an annular groove 22 recessed in the joint surface 21, and the joint flange 20 is provided with a plurality of screw holes 23. When assembled, the sealing member 10 is formed in the annular groove 22 of the joint flange 20.

Please refer to the second figure, which is a second embodiment of the improved joint flange structure. The shallow groove 221 is disposed on the side of the annular groove 22 of the joint flange 20, and the shallow groove 221 is adjacent to the annular groove 22, and the shallow groove 221 is annular. A bent portion 41 formed by bending the end portion of the bellows joint 40 is formed, and the bent portion 41 abuts against the inner edge of the sealing member 10 to form a better sealing structure.

Please refer to the second figure, which is a third embodiment of the improved joint flange structure. The side of the annular groove 22 of the joint flange 20 is further provided with a shallow groove 221 which is the same as the implementation. For example, the inner ring wall surface of the sealing member 10 is provided with a concave ring 12 for inserting the bent portion 41 at the end of the telescopic pipe joint 40 to provide a better sealing structure.

Please refer to the third figure, which is a fourth embodiment of the creation of the combined flange structure. The engaging portion 13 of the sealing member 10 has a round shape.

In the implementation, please refer to the fourth figure, which is a cross-sectional view showing the state of use of the sealing member 10 and the joint flange 20 in the first figure. A telescopic pipe joint 40 is mounted on the joint flange 20, and the expansion pipe joint 40 is pressed by the sealing member 10. The sealing member 10 is correspondingly engaged with the groove 22 of the joint flange 20, and a plurality of bolts A are provided for connection. The screw hole 23 of the flange 20 is locked to the joint flange 31 of a pipe 30, and is engaged by the plurality of nuts B, so that the joint flange 20 and the joint flange 31 of the pipe 30 are tightly coupled to each other. Density or airtight effect.

Please refer to the fifth drawing, which is a cross-sectional view showing the state of use of the sealing member 10 in the third figure. Since the engaging portion 13 of the sealing member 10 has a round shape, the groove 22 of the joint flange 20 also needs to match its shape to achieve an optimum gas-liquid tightness effect.

Referring to the sixth embodiment, the sealing member 10 is a variation of the third embodiment. The cross section of the sealing member 10 has an inverted shape and has a concave ring 12 facing the inner side, thereby joining the bent portion 41 of the telescopic joint 40. And achieve the best gas-liquid tight effect.

The detailed description above is for the specific description of the possible embodiments of the present invention, but the embodiment is not intended to limit the scope of the patents of the present invention, and equivalent implementations or changes that are not departing from the spirit of the present invention should be included in the present case. In the scope of patents.

In summary, under the previous technical structure, this creation has indeed achieved the desired effect, and it is not easy for the skilled person to think about it. Moreover, this creation has not been disclosed before the application. The progressiveness and practicability have already met the requirements for the application of new patents, and new applications have been filed according to law. You are requested to approve the application for this new type of patent to encourage creation.
