Description

Technical Field

[0001] This utility model relates to the field of pressure welding technology for thermal pipelines, specifically a device for simultaneous pressure welding of thermal pipelines. Background Technology

[0002] Heat pipelines are widely used in urban heating, industrial heat energy transmission and other fields. With the acceleration of urbanization, the demand for heating is gradually increasing, and the construction and maintenance of heat pipelines are particularly important. The simultaneous pressure testing and welding construction technology of heat pipelines is an important innovation to address the shortcomings of traditional construction methods. With the continuous development and application of technology, this method will be more widely promoted and applied in the construction of heat pipelines.

[0003] After the existing heating pipelines are welded, strength and tightness tests are usually conducted according to the actual site conditions. Water pressure tests are generally used on site, which usually take a long time. During this time, pipeline welding cannot be carried out, which has a certain impact on the overall pipeline construction efficiency, thereby reducing construction efficiency and increasing construction costs. Moreover, the plugs must be cut before welding can be carried out, thus reducing the adaptability of the heating pipeline pressure welding device. Utility Model Content

[0004] The purpose of this invention is to provide a device for simultaneous pressure testing and welding of thermal pipelines, which solves the problem in the prior art that welding operations can only be carried out after the plug is cut.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A device for simultaneous pressure testing and welding of thermal pipelines, comprising:

[0007] A first heating pipe has a second heating pipe installed at one end. A pressure testing end is fixedly installed at the end of the first heating pipe away from the second heating pipe, and a welding end is fixedly installed at the end of the second heating pipe away from the first heating pipe. The first and second heating pipes are welded to the pressure testing end and the welding end, respectively. The heating pipe material has high hardness, strength, and bending resistance to facilitate pressure testing and welding of the pressure testing end and the welding end.

[0008] The connecting and sealing assembly includes a pipe plug fixedly installed between a first heating pipe and a second heating pipe. An auxiliary fixing component is fixedly installed between the pipe plug and the first and second heating pipes. The pipe plug is connected to the heating pipe by welding and ribs, which on the one hand ensures the pressure testing quality of the heating pipe and keeps the pressure testing area in a sealed environment; on the other hand, it serves to separate the pressure testing area from the welding area.

[0009] Preferably, the auxiliary fixing assembly includes a plurality of fixing mounting plates fixedly installed on the pipe plug, and the plurality of fixing mounting plates are fixedly installed on the first heating pipe and the second heating pipe respectively at one end near the first heating pipe and the second heating pipe.

[0010] Preferably, an auxiliary pressure testing assembly is provided at the top of the first heating pipe. The auxiliary pressure testing assembly includes a pressure testing port fixedly installed at the top of the first heating pipe. The pressure testing port is located between the pressure testing end of the heating pipe and the pipe plug. The pressure testing port serves as the location for controlling the pressure testing pressure in the pressure testing area and for installing the pressure gauge. The installation of the pressure testing port facilitates the pressure testing process after the device is installed.

[0011] Preferably, a water pressure testing assembly is provided at the top of the first heating pipe. The water pressure testing assembly includes a water inlet fixedly installed at the top of the first heating pipe. The water inlet is located between the pressure testing port and the pipe plug. The water inlet serves as the water injection point for the water pressure test. The water inlet facilitates the water pressure test after the pressure testing of the first heating pipe and the pressure testing end of the heating pipe is completed, so as to facilitate the subsequent use and processing of the pressure testing end of the heating pipe and the first heating pipe. Moreover, it avoids leakage between the pressure testing end of the heating pipe and the first heating pipe, thereby improving the sealing performance of the pressure testing end of the heating pipe and the first heating pipe.

[0012] Preferably, an installation assembly is provided between the pipe plug and the first and second heating pipes. The installation assembly includes two inner-lined joint pipes fixedly installed at both ends of the inner-lined joint pipe. The two inner-lined joint pipes are respectively fixedly installed on the first and second heating pipes. Both inner-lined joint pipes are located inside the first and second heating pipes. The inner-lined joint pipes can effectively improve the stability of the pipe plug and the first and second heating pipes, preventing the pipe plug from falling off the first and second heating pipes, so as to facilitate the pressure testing and welding of the heating pipes. At the same time, it can reduce some shaking, making the pressure testing end and welding end of the heating pipe more stable during pressure testing and welding, thereby improving the pressure testing and welding efficiency of the pressure testing end and welding end of the heating pipe.

[0013] Preferably, the pipe plug is provided with an auxiliary welding hole, which is used to fix the two inner lining joint pipes to the first and second heating pipes. The auxiliary welding hole can quickly weld and fix the inner lining joint pipes to the first and second heating pipes, so as to improve the stability of the first and second heating pipes during welding pressure testing.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] 1. This utility model, through the setting of connecting sealing components and auxiliary fixing components, enables simultaneous construction of thermal pipeline welding and pressure testing, overcoming the limitation of existing devices that cannot weld and pressure test thermal pipelines. Moreover, the thermal pipeline device has a simple structure and high construction efficiency. Compared with ordinary pressure testing plugs, there is no need to wait for the plug to be cut before welding, resulting in higher work efficiency and a wider range of applications, greatly improving the adaptability of the thermal pipeline pressure testing and welding device.

[0016] 2. By setting up the installation components, the auxiliary components of this utility model can ensure the accurate position of the heat pipe during welding and pressure testing, while reducing the subsequent adjustment time. They can also provide stable support for the heat pipe, and the installation process is simpler and more intuitive, reducing installation difficulty and improving work efficiency. At the same time, it can prevent the heat pipe from slipping during simultaneous pressure testing and welding, ensuring the safety of operators and greatly improving the safety of the device.
