Description

Technical Field

[0001] The utility model relates to the technical field of fan coil units, in particular to a new type of precision-cast stainless steel water distribution and collection head. Background Technique

[0002] The main function of the water distribution head is to effectively distribute chilled water or hot water into multiple flow paths. These flow paths pass through the copper tubes in the surface cooler or heater for heat exchange. In this process, the water flow exchanges heat with the surrounding air or other media through the copper tubes. Finally, the water in each flow path will flow to a water collection head for convergence after heat exchange, which can ensure that the system can evenly distribute cold or hot water and improve the overall heat exchange efficiency.

[0003] The existing water distribution and collection heads usually connect multiple water distribution pipes to effectively distribute chilled water or hot water into multiple flow paths. For example, Chinese Patent Publication No. CN217382116U discloses "a stainless steel water distribution and collection head", which is convenient to observe whether there is water or blockage inside through the detection holes opened on the side wall of the main body. Due to the curved surface at the bottom of the main body, the contact area can be greatly increased, facilitating the installation of a larger number of water distribution pipes.

[0004] However, in actual use, since gas is easily mixed into the liquid inside the water distribution and collection head, if the gas is not discharged, it will affect the use effect of the surface cooler or heater, and the impurities in the liquid are likely to accumulate to form large-volume impurities, which will cause liquid blockage. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Refer to Figures 1-3, A new type of precision-cast stainless steel distribution header, including a connecting part 1, a water distribution part 2 is fixedly connected to the connecting part 1, a plurality of water distribution holes 3 are opened on the water distribution part 2, a water distribution pipe is fixedly arranged on the water distribution holes 3, a connecting component 4 is arranged on the water distribution part 2, and the water distribution part 2 is detachably connected with an exhaust valve through the connecting component 4. An installation plate 5 is fixedly arranged on the connecting part 1, and the connecting part 1 and the water distribution part 2 are an integrally precision-cast structure.

[0022] In the present utility model, by arranging an exhaust valve on the water distribution part 2, the gas in the distribution header is discharged, avoiding affecting the use effect of the surface cooler or heater, and the exhaust valve can be detached for cleaning. The connecting part 1 and the water distribution part 2 are an integrally formed structure, made of the same piece of material, so there is no joint, the overall structure is more solid, can better withstand pressure and external forces, has better sealing performance in aspects such as leak prevention, and reduces the risk of leakage.

[0023] Further, in this embodiment, the connecting component 4 includes a threaded hole 41, the threaded hole 41 communicates with the water distribution part 2. In some embodiments, a sealing gasket is arranged in the threaded hole 41. When installing the exhaust valve, the exhaust valve abuts against the sealing gasket to form a sealing structure to prevent leakage.

[0024] Furthermore, in this embodiment, the connecting component 4 further includes a boss 42 integrally formed with the water distribution part 2, and the threaded hole 41 is opened on the boss 42. By arranging the boss 42, the requirements for subsequent tapping can be met. In this way, when the exhaust valve is assembled in the hole later, it is on the side, which will not affect the assembly of other components, and the overall configuration is more reasonable.

[0025] It should be noted that, in this embodiment, a filtering structure 6 is arranged in the water distribution part 2. The liquid passing through is filtered by the filtering structure 6, and the impurities gathered into large volumes are filtered out, so as to avoid causing liquid blockage and ensure smooth liquid circulation.

When the filter cover 61 is installed, the rubber rings 71 will undergo elastic deformation, so that the inner walls of the rubber rings 71 are all in contact with the filter cover 61. The liquid is filtered by the filter cover 61, and the filter cover 61 can be taken out for cleaning and replacement.

[0028] Working mode; during operation, by setting an exhaust valve on the water distribution part 2, the gas in the manifold head is discharged to avoid affecting the use effect of the surface cooler or heater, and the exhaust valve is detachable for cleaning. The connecting part 1 and the water distribution part 2 are integrally formed structures made of the same piece of material, so there is no seam and the overall structure is more solid. By setting the boss 42, the requirements for subsequent tapping can be met.
