Technical Field

[0001] The invention relates to the technical field of heating, ventilation and air conditioning systems, and in particular to a standard prefabricated pipe and process for phase-change cold storage and heating air conditioning equipment. Background Art

[0002] At present, there are many valves and valve parts near one end of the fan coil units and air-cooled heat pumps in the society. Due to the uncertainty of the on-site environment and the rapid replacement requirements of factory production, there is an urgent need for a pipe fitting that can be quickly replaced and applied in any scenario, saving labor. The main defects of the traditional on-site installation of single valve parts are:

[0003] (1) When installing a single valve, the on-site working space is narrow and it is difficult for personnel to enter and exit.

[0004] (ii) When installing valves one by one, it is easy for them to be installed loosely, resulting in water leakage.

[0005] (III) As it involves a variety of valve components, it is easy for the site to be incompletely prepared, thus delaying the construction period.

[0006] (IV) Traditional valve installation is not suitable for rapid processing and does not meet the needs of emergency repairs. For this reason, we have improved the above-mentioned existing technology based on actual usage. Summary of the invention

After the purchase arrives at the site, conduct a trial combination with the prefabricated pipes. From the trial combination, check the matching of the valves and prefabricated pipes and the reliability evaluation of factory prefabrication. At the same time, further clarify the relative position relationship and corresponding assembly direction of each valve. According to the combination size, determine the length of the connection section of the prefabricated pipe and the thread processing specifications, and reserve enough prefabricated pipe length according to the specification requirements, and reasonably arrange the direction of the external valve stem of the valve fittings;

[0013] S2: For standard pipe fittings, the outlet and inlet ends are clearly defined to facilitate factory prefabrication personnel to process different joints at both ends separately to prevent processing errors.

[0022] A process for manufacturing a standard prefabricated tube for phase change cold storage heating air conditioning equipment, characterized in that the process comprises the following steps:

[0023] S1: According to the specific needs of design and installation, determine the appropriate valves and valve parts. Because the water pipe runs for hot and cold water exchange (45 degrees Celsius in winter and 7 degrees Celsius in summer), pay attention to the cold and heat resistance requirements of the pipe when selecting materials, that is, the solenoid valve 2, the ball valve 3 and the Y-type filter 6. It should be noted that when installing the Y-type filter 6, the water outlet and water supply directions must be considered, and it must not be installed in reverse. The selection, specifications and technical parameters of the valves and valve parts on the prefabricated pipe 9 are reviewed. After confirmation, the valves and valve parts are purchased. After the purchase arrives on site, the prefabricated pipe 9 is included in the trial combination. From the trial combination, check the matching of the valve and the prefabricated pipe 9 and the reliability evaluation of the factory prefabrication. At the same time, further clarify the relative position relationship and corresponding assembly direction of each valve. According to the combination size, determine the length of the connection section of the prefabricated pipe 9 and the thread processing specifications, and leave enough prefabricated pipe 9 length in accordance with the specification requirements. Reasonably arrange the direction of the external valve stem of the valve fittings. The direction of the valve stem should be combined with the on-site decorative surface and on-site position to facilitate later operation;

[0024] S2: For standard pipe fittings, the outlet and inlet ends are clearly defined to facilitate factory prefabrication personnel to process different joints at both ends separately to prevent processing errors. The outlet end adopts a groove connection form to facilitate rapid installation on the construction site. The groove pressure groove depth and width meet the requirements of the specification. The inlet end adopts an external thread. When making, the thread specifications of the inner sleeve of the metal hose 4 connected to the equipment are measured in advance, and the installation sequence of the valve equipment is combined. For conventional diameters below 80mm, threaded connections are uniformly used, and the rubber pads selected in the groove must adapt to the changes in cold and hot expansion caused by the cold and hot exchange of the water pipe;

[0025] S3: After the standard pipe fittings are manufactured, they are assembled on site for trial and any problems encountered during the assembly process are promptly adjusted.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
