Description

Technical Field

[0001] The utility model relates to the technical field of flanges, and particularly relates to a quick-connect flange structure. Background Art

[0002] A flange, also known as a flange convex disc or a flange. A flange is a part used for connecting pipes to each other, and is used for connecting between pipe ends; there are also flanges used at the inlets and outlets of equipment for connecting between two pieces of equipment, such as a reducer flange.

[0003] Traditional pipeline flange connection is achieved by connecting two identical flanges through a sealing gasket, nuts, and bolts. Since the nuts and bolts are independently arranged, during the construction and installation process, a wrench needs to be used to tighten the nuts and bolts simultaneously to tighten the two flanges or the pipeline flange and the equipment flange; the operation process is troublesome, and many tools are used. Workers need to carry many tools to complete the installation. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned existing problems and provide a quick-connect flange structure. During the installation process of this structure, workers do not need to carry many tools either. Only one tool is required, and the operation is very convenient, which can improve work efficiency and reduce the construction difficulty of workers.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A quick-connect flange structure includes a first flange, a second flange, and a connection mechanism for connecting the first flange and the second flange; wherein, the connection mechanism includes a nut and a bolt; the nut is arranged on the first flange, and the nut and the first flange are of an integral structure; the bolt passes through the second flange and is cooperatively connected with the nut.

[0007] The working principle of the above-mentioned quick-connect flange structure is as follows:

[0008] During the production process of the first flange, the originally independent component nut is added to the first flange for production together, so that the first flange and the nut are of an integral structure. In this way, during the actual installation process, it is not necessary to use a wrench to tighten both the nut and the bolt. Only one wrench is needed to tighten the bolt to tighten the flange structure. Workers do not need to carry many tools either. Only one tool is required. This can improve work efficiency and reduce the construction difficulty of workers, especially when performing high-altitude operations, it can greatly improve the work efficiency of workers.

[0009] A preferred embodiment of the present utility model, wherein a protruding portion is provided on the outer end surface of the first flange, and the protruding portion forms the nut. The purpose is to ensure that the thickness of the first flange does not need to be too thick by matching the nut with the bolt, so as to achieve stable connection and make the whole structure very compact.

[0010] Preferably, a through hole for the bolt to pass through is provided on the second flange; a threaded hole is provided on the nut, and the threaded hole extends to the inner end surface of the first flange. With the above structure, when the first flange is connected to the second flange, after the bolt passes through the through hole, it cooperates with the threaded hole. During installation, the bolt can be tightened with a wrench to complete the installation. The threaded hole extends to the inner end surface of the first flange, so that the threaded hole has a longer distance, which can improve the connection stability; or on the premise of ensuring the existing flange connection performance, since the threaded hole extends to the inner end surface of the first flange, the length of the threaded hole is larger than that of the threaded hole of the nut in the prior art. Therefore, the length of the first flange or the nut of the present utility model can be set smaller than that of the prior art, and the connection performance remains unchanged, making the structure more compact.

[0011] Preferably, a chamfer is provided at the position of the threaded hole near the inner end surface of the first flange. The purpose is to facilitate the guiding of the bolt during installation and make it easier to connect the bolt with the threaded hole.

[0012] Preferably, a sealing gasket is provided between the first flange and the second flange. By providing the sealing gasket, the sealing performance between the first flange and the second flange can be improved.

[0013] Preferably, a washer is provided between the bolt and the outer end surface of the second flange. The purpose is to improve the connection stability of the bolt.

[0014] Preferably, the quick-connect flange structure is used to connect two pipelines; the first flange is installed on one pipeline, and the second flange is installed on the other pipeline. The quick-connect flange structure can achieve stable connection of two pipelines, and the connection process is very simple.

[0015] Preferably, the quick-connect flange structure is used to connect a pipeline and a valve body; the first flange is installed on the pipeline, and the second flange is installed on the valve body. The quick-connect flange structure can achieve stable connection of the pipeline and the valve body, and the connection process is very simple.

[0017] The present utility model has the following beneficial effects compared with the prior art:

[0018] In the quick-connect flange structure of the present utility model, the first flange and the nut are of an integral structure. In this way, during the actual installation process, it is not necessary to use a wrench (i.e., a tool) to tighten both the nut and the bolt. Only one wrench is needed to tighten the bolt to tighten the flange structure. Therefore, the staff does not need to carry a lot of tools and only one tool can be used, which can improve work efficiency and reduce the construction difficulty of workers. Especially during high-altitude operations, it can greatly improve the work efficiency of workers. BRIEF DESCRIPTION OF THE DRAWINGS

During installation, tightening the bolt 4 with a wrench can achieve the installation. The threaded hole 7 extends to the inner end face of the first flange 1, so that the threaded hole 7 has a longer distance, which can improve the connection stability; or on the premise of ensuring the existing flange connection performance, since the threaded hole 7 extends to the inner end face of the first flange 1, the length of the threaded hole 7 is larger than the length of the threaded hole 7 of the nut 3 in the prior art. Therefore, the length of the first flange 1 or the nut 3 of the present invention can be set smaller than that of the prior art, and the connection performance remains unchanged, which can make the structure more compact.
