Description

Technical Field

[0001] The utility model relates to the technical field of low-pressure circulating liquid supply devices, in particular to a pipeline anti-frost mechanism of a low-pressure circulating liquid supply device. Background Art

[0002] The liquid supply refrigeration system is a refrigeration system with different characteristics connected by different pipes. It is a device used in close combination with multiple types of work such as construction, structure, water supply and drainage, heating and ventilation, mechanical transmission, electric power and lighting, and automatic control. The low-pressure circulating liquid supply device is a transmission pipeline used in the liquid supply refrigeration system. Its function is to ensure that low-pressure liquid or gas is fully supplied to the liquid supply refrigeration system. There are at least the following disadvantages in the use of the existing low-pressure circulating liquid supply device pipeline anti-frost mechanism: during the circulation process, the low-temperature liquid inside the pipeline will form a temperature difference with the outside air temperature, so that the outer wall of the pipeline has a lower temperature, so that the moisture in the air is condensed into frost by its low temperature and adheres to the outer surface of the pipeline, thereby causing frost on the outside of the pipeline. The frosted pipeline will cause the expansion valve to freeze and block, causing the pipeline to rupture, affecting the normal operation of the machine, and the protection is poor; therefore, we introduce a low-pressure circulating liquid supply device pipeline anti-frost mechanism. Utility Model Content

[0003] The main purpose of the utility model is to provide a low-pressure circulating liquid supply device pipeline anti-frost mechanism, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A low-pressure circulating liquid supply device pipeline anti-frost mechanism comprises a pipeline, the inner wall of the pipeline is fixedly connected with a heating device, the lower part of the outer surface of the pipeline is movably connected with a bearing device, the upper end of the bearing device is clamped with a connecting device, the upper four corners of the bearing device are threadedly connected with fixing bolts, and four fixing bolts are provided;

[0006] The heating device includes an inner tube, an inner groove is opened in the middle of the right end of the inner tube, a button is arranged at the front of the right end of the inner tube, a circular groove is opened on the outer surface of the inner tube, a plurality of heating rods are fixedly connected between the left groove wall and the right groove wall of the circular groove, and the inner tube is fixedly connected to the inner wall of the pipeline.

[0007] Preferably, the supporting device includes a lower connecting plate, the four corners of the upper end of the lower connecting plate are fixedly connected with short screws, the inner plate wall of the lower connecting plate is fixedly connected with a first insulation layer, and the lower connecting plate is located at the lower part of the outer surface of the pipe.

[0008] Preferably, the connecting device includes an upper connecting plate, the upper end of which is provided with through holes at four corners, the inner plate wall of the upper connecting plate is fixedly connected with a second insulation layer, and the upper connecting plate is located on the upper outer surface of the pipeline.

[0009] Preferably, the positional dimensions of the four short screws are matched with the positional dimensions of the four through holes.

[0010] Preferably, the positional dimensions of the four short screws are matched with the positional dimensions of the four fixing bolts.

[0011] Preferably, the structure of the upper connecting plate is the same as that of the lower connecting plate and they are symmetrically distributed up and down.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting a heating device, a plurality of heating rods are controlled manually through an external control device to heat the inner tube so that the inner tube is kept at room temperature. The temperature can be controlled at a constant temperature to form a low-temperature heating rod. In combination with the insulation effect of the first insulation layer and the second insulation layer, the temperature of the outer wall of the inner tube is constant during the inner tube working and conveying process. This avoids the phenomenon that the temperature of the outer wall of the inner tube continues to drop after a long period of work due to the continuous conveyance of low-temperature liquid by the inner tube, thereby avoiding the phenomenon that the liquid in the inner tube is frosted again, thereby improving the anti-frost performance of the present application.

[0014] 2. By setting the bearing device and the connecting device, since the position size of the four short screws is adapted to the position size of the four insertion holes, the short screws are passed through the insertion holes and are threadedly fixed with fixing bolts, so that the upper connecting plate and the lower connecting plate are fixedly installed on the outer surface of the pipeline, which can protect the pipeline and adopt the threaded installation method, which is convenient for disassembly and assembly.
