Description

Technical Field

[0001] The utility model relates to the technical field of fan coil unit accessories, in particular to a filterable water flow distributor for a fan coil unit. Background Art

[0002] Water flow distributors are usually divided into water collectors and water distributors. The water distributor is installed at the water inlet of the fan coil unit and is a distribution device that divides one water inlet into multiple water inlets. The water collector is installed at the water outlet of the fan coil unit and is a collection device that collects the multiple water outlets flowing through the fan coil unit into one water outlet. The water distributor distributes the water flow of the system main pipe into the fan coil unit according to the designed flow rate. At the same time, the water collector collects the water flow of each branch circuit out of the fan coil unit and inputs it into the main pipe to achieve circulation operation.

[0003] The patent announcement number previously applied by our company is "CN 113654105 A", which discloses a new water flow distributor for a fan coil unit. The patent disclosure includes a cavity structure and a connecting part that are connected to each other. The cavity structure is open at one end, and a plurality of diversion holes are arranged on the end wall or side wall at the other end. The open end of the cavity structure is provided with a countersunk hole for accommodating the connecting part. One end of the connecting part is fixed in the countersunk hole, and a diversion branch pipe is fixed at the diversion hole.

[0004] There are still some deficiencies in practical application. During long-term use, the above-mentioned patent disclosure may contain impurities in the water, which may easily adhere to the tube wall and affect the use effect. Utility Model Content

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] Reference Figure 1-2A water flow distributor for a filterable fan coil unit comprises a cavity 1 for distributing or converging water flow and a connecting portion 3 with openings at both ends, a plurality of diversion holes are provided on the end wall or side wall of the cavity 1 for fixing a diversion branch pipe 8, an air release valve 7 is also provided on the cavity 1, a connecting portion 2 is provided between the cavity 1 and the connecting portion 3, an extension head 4 is provided which is obliquely connected to the connecting portion 2 and one side of the cavity 1, a filter component 6 is detachably placed inside the extension head 4, and the end of the extension head 4 is blocked by a blocking cover 5.

[0023] A threaded structure is provided at the inner lower end of the connecting part 3, and three groups of ear plates are provided at the upper end of the outer wall of the connecting part 3, and the ear plate and the connecting part 3 are cast as one piece. The water flow distributor adopts a segmented design, and one section is a cavity 1 part with a larger inner diameter, which is used to better accommodate and distribute the water flow. The inner side of the lower end of the connecting part 3 is threaded, which is used to connect with the water inlet or outlet of each circuit of the fan coil unit. Compared with the one-piece water flow distributor, this structure has a connecting part 3 connected to the cavity 1 through a connecting part 2, and the wall thickness of the cavity 1 part is thinner and the inner diameter is larger, so as to better meet the needs of water flow, save the use of materials, and reduce costs while meeting functional needs. The structural form of the connecting part 3 can be selected as needed. In addition, the diversion hole is located on the end wall or side wall of the cavity 1, and a larger number of holes can be arranged to meet the number requirements of the diversion branch pipe 8. When the water flow distributor is used as a water collector, when the fluid flows and bubbles are generated, the air release valve 7 can be opened to exhaust.

[0024] The extension head 4 is extended obliquely upward from the connecting part 2 and the cavity 1; the connecting part 2 is an inverted trumpet-shaped structure as a whole, and the diameter of the bottom of the connecting part 2 is smaller than the diameter of the filter component 6; the diameter of the filter component 6 is compatible with the diameter of the extension head 4, and the length of the filter component 6 is larger than the maximum diameter of the connecting part 2; the blocking cover 5 can be rotatably opened, and the filter component 6 is inserted from the extension head 4 so that the filter component 6 is at the connecting part 2, so that the impurities in the water input into the connecting part 2 can be filtered, and the blocking cover 5 has a boss in the middle of one side facing the extension head 4. When the blocking cover 5 is rotated onto the extension head 4, the boss in the middle of the blocking cover 5 can contact the filter component 6, thereby restricting the filter component 6, so as to facilitate filtering of impurities in the water through the filter component 6.

[0025] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
