AI Technical Summary
Existing pipe connection methods have problems such as many installation procedures, complicated operation and high cost. In particular, welded connections are prone to rust and corrosion of exposed sealing rings.
The pipe connection structure adopts a cam-type pipe connection structure, which uses the cam on the pipe end and fastening bolts for connection. Combined with sealing rings and reinforcing parts, a stable connection is achieved through concentric connection holes, avoiding exposure of the sealing ring and leakage under high pressure.
It enables quick and simple pipe connections, reduces costs, and maintains good sealing and corrosion resistance, avoiding deformation and leakage of the sealing ring.

TECHNICAL FIELD
[0001] The utility model relates to a convex disc type pipe connecting structure and belongs to the technical field of pipeline connection. BACKGROUND
[0002] With the improvement of people's living standard, the living space is required to be more perfect, comfortable, modern and humanistic. The environment, facilities and use function of buildings are also required to be higher and higher, and various new equipment, new materials and new technology are constantly updated and emerge in an endless stream. The wide application in building construction is to better meet the increasing material and cultural use function requirements. The pipeline industry is developing rapidly at present, and various pipelines adopt different connecting modes. At present, the commonly used connecting modes of pipelines are various, including sleeve type connection, clamping type connection, hot melting connection, adhesive connection, threaded connection, welding connection, flange connection, socket connection and groove connection. At present, the connecting modes for pipelines mainly include compression type connecting structure and welding type connecting structure.
[0003] The compression type connecting structure is that the pipe material is inserted into the pipe fitting, and then the sealing ring is compressed to play a sealing role through the nut fastening. This connecting mode has many installation procedures and high cost. During installation, the pipe material needs to be expanded by using special tools, and the threads also need to be pre-welded with the pipe body. The welding type connecting structure is that the pipe material is inserted into the pipe fitting, and then the welding is performed at the insertion position. This connecting mode is troublesome to construct. Electricity must be used on site, the temperature of the welded part is high, and the phenomenon of chromium depletion is prone to occur. The solid solution treatment cannot be performed on site, so the welded part is prone to rust. CONTENT OF THE UTILITY MODEL
[0004] In order to make up for the above shortcomings, the utility model provides a convex disc type pipe connecting structure, which aims to improve the problem of many installation procedures and troublesome operation of the connecting structure of the pipeline in the prior art.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A convex disc type pipe connecting structure, which is applied to pipe fitting port connection and includes a pipe fitting, a sealing ring, a reinforcing part and a fastening bolt. The pipe fitting port is provided with a convex disc. When the pipe fitting is connected and assembled, the convex discs on adjacent pipe fittings are connected relative to each other. The sealing ring is located between the relative distribution of the convex discs. The fastening bolt passes through the convex disc, the sealing ring and the reinforcing part for fastening. The reinforcing part is located on the outer wall of the convex disc.
[0007] Preferably, the convex disc includes a connecting section and a limiting section. The limiting section is a boss structure on the port of the connecting section. The connecting section is used for arranging the sealing ring. The limiting section prevents the fastening bolt from excessively extruding the sealing ring during the installation of the fastening bolt, and ensures that the sealing ring synchronizes with the material during thermal expansion and cold contraction.
[0008] Preferably, the convex disc connecting section, the sealing ring and the reinforcing member are provided with concentric connecting holes, so that the connecting structure is stable and displacement is prevented.
[0009] Compared with the prior art, the convex disc type pipe connecting structure has the advantages that the flange type connecting assembly structure is replaced, the sealing ring can be effectively protected and is not exposed outside, flange connection effects can be achieved, the cost is lower than that of the flange connection mode, the convex disc structure can effectively prevent the sealing ring from moving, exposure of the sealing ring to light is avoided, the sealing ring can withstand high fluid pressure, installation personnel are not required to have technical operation skills, the bolt pressure is tightened on the sealing section, pipe fittings and pipe materials can be quickly connected, installation operation is simple, the structure is strong, the cost is low, the sealing part can make the convex disc type pipe connecting structure maintain good sealing performance, long-term deformation-free and leak-free effects can be achieved, and the flange connection effects can be achieved in the optimal connection mode in pipeline connection.
