Description

Fastening fixture for pipe fastening

technical field

The utility model relates to a fastening fixture, in particular to a simple and fast fastening fixture for pipelines, which belongs to the technical field of machinery. the

Background technique

Various fluids are often used in chemical experiments and chemical production to participate in reactions and collect products. The most straightforward way to transfer fluids is through pipes. In chemical experiments, pipelines need to be frequently installed and disassembled to replace internal experimental equipment. the

At present, when encountering pipe flange butt joints without reserved fastening devices, it is usually necessary to change the design and replace the pipe and flange. For this type of pipe, tools are usually required for installation and removal. During the installation and disassembly process, all fastening screws usually need to be assembled and disassembled, so the installation and disassembly steps are cumbersome, which wastes manpower and time. Therefore, there is an urgent need for a fast butt joint fastening fixture to improve work efficiency and achieve a reliable sealing effect at the same time. the

Utility model content

Aiming at the deficiencies of the existing technology, the purpose of this utility model is to provide a fast butt joint fastening fixture for pipes with simple structure, convenient use, low cost, improved work efficiency and reliable sealing effect, so as to meet the market demand . the

In order to achieve the above object, the technical scheme that the utility model takes is as follows:

A fast butt joint fastening fixture for pipelines, including two pipelines to be connected and pipeline flanges, one side of the pipeline flange is provided with an integrated part, and the other side of the pipeline flange is provided with a first flange plate, integrated The integrated part and the first flange plate are flexibly connected by a wing nut; the integrated part includes a second flange plate, and there is a "U"-shaped bayonet in the middle of the second flange plate, which is stuck on the pipe and fixed on both sides There are connecting screws and fixing nuts; there is a "U"-shaped bayonet in the middle of the first flange plate, and holes for installing screws are provided on both sides of the bayonet away from the bayonet. the

As a preferred solution, in the above-mentioned quick-joint fastening fixture for pipelines, a gasket is provided between the pipeline flanges. the

As a preferred solution, the sealing pad of the above-mentioned quick-joint fastening fixture for pipelines is made of silica gel. the

The beneficial effects of the utility model are: it is suitable for but not limited to butt joints and sealing fixation of pipelines that require frequent disassembly and assembly in various catalytic experiments, and is especially suitable for workplaces where the original pipeline flange does not have a fastening device reserved; the utility model through Tighten and loosen the wing nut by hand to achieve the purpose of quick installation and disassembly of the pipe butt joint, and effectively play a sealing role; tighten the wing nut to tighten the clamp to play the role of sealing and fixing; according to the aforementioned reverse steps, The pipe can be disassembled by loosening the butterfly nut and loosening the clamp; the installation and disassembly process can be done manually; the structure is simple, easy to use, low cost, can improve work efficiency, and at the same time achieve a reliable sealing effect. the

Detailed ways

Below in conjunction with accompanying drawing and embodiment thereof, the utility model is described in further detail. the

The utility model is used for quickly installing and dismantling the butt joint sealing of gas pipelines, taking the gas-phase catalytic reaction device installed in the research group of mesoporous and low-dimensional nanomaterials of Shanghai Institute of Ceramics, Chinese Academy of Sciences as an example. The gas pipeline of the original reaction device did not reserve pipeline flanges for butt fastening during design, and it required frequent installation and disassembly. the

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4: the utility model is a fast butt joint fastening fixture for pipes, which includes two pipes 7 and 8 to be butted, pipe flanges 9 and 10, and one side of the pipe An integrated part is provided outside the flange, and a first flange plate 1 is provided outside the flange of the pipe on the other side, and the integrated part and the first flange 1 are movably connected by a wing nut 6; the integrated part includes the first The second flange plate 2 has a "U"-shaped bayonet in the middle of the second flange plate 2, which is stuck on the pipe 7, and the two sides are fixed with connecting screws 4 and fixing nuts 5; the middle of the first flange plate 1 has a "U"-shaped bayonet, on both sides of the bayonet far away from the bayonet are provided with holes for mounting screws. Tighten the butterfly nut 6 to tighten the fixture to play the role of sealing and fixing. Unscrew the wing nut 6 to loosen the clamp and the pipeline can be disassembled. The installation and disassembly process can all be realized manually. A gasket 3 is provided between the pipeline flanges 9 and 10. The gasket 3 is made of silica gel, which depends on the nature of the fluid transmitted in the pipeline during actual use. the

With the utility model, all the installation and disassembly processes can be realized manually, and the installation and disassembly processes only need a few seconds. After the seal is installed as described in this example, when the air pressure in the pipeline reaches 0.2MPa, the measured sealing performance is good, which can meet the experimental requirements. the

Finally, it should be noted that the above description is not a limitation of the present utility model, and the present utility model is not limited to the above-mentioned examples. Those of ordinary skill in the art can make changes, modifications, Addition or replacement should belong to the protection scope of the present utility model. the
