[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] like Figure 1-Figure 3 As shown, a universal filtering device for water supply, drainage and heating includes a filter tube 1, an adapter seat 3 is fixedly installed in the center of the outer ring of the filter tube 1, a valve 2 is installed through the top end of the filter tube 1 and located behind the adapter seat 3, a filter mesh frame 4 is arranged through the top end of the filter tube 1 and located at the position of the adapter seat 3, a locking head 5 is fixedly installed through the bottom end of the adapter seat 3, a locking threaded sleeve 6 is arranged on the outer ring of the locking head 5, and a collecting assembly 7 is arranged at the bottom end of the locking head 5.
[0019] The collecting assembly 7 includes a collecting tube 701, inside of which a vertical filter screen 702 is fixedly installed, and a transfer metal hose 8 is provided at the bottom of the collecting tube 701. The collecting assembly 7 is provided to facilitate the collection of foreign matter left after filtering, and facilitate the subsequent cleaning of foreign matter.
[0020] The filter screen frame 4 is arranged to be tilted forward, and the filter screen frame 4 is snap-connected with the filter tube 1 and the adapter 3. The water entering the filter tube 1 is filtered by setting the tilted filter screen frame 4. At the same time, the snap-connection setting facilitates the disassembly of the filter screen frame 4, and facilitates the installation and replacement of the filter screen frame 4.
[0021] The locking threaded sleeve 6 is threadedly connected to the locking head 5, and the locking head 5 is communicated with the interior of the filter tube 1. The locking threaded sleeve 6 is provided to facilitate the closing of the locking head 5 after tightening.
[0022] The top end of the collecting tube 701 is engaged with the locking head 5 , and the foreign matter intercepted by the filter frame 4 passes through the locking head 5 and falls into the collecting tube 701 , where the foreign matter is collected.
[0023] The bottom of the collecting pipe 701 is threadedly connected to one end of the transition metal hose 8, the other end of the transition metal hose 8 is fixedly connected to the vertical section of the filter tube 1, and the transition metal hose 8 is connected to the interior of the filter tube 1. The vertical filter screen 702 is arranged in a hollow cone shape. After foreign matter follows the water flow into the collecting pipe 701, the foreign matter is intercepted by the vertical filter screen 702. After the water flow passes through the vertical filter screen 702, it flows back to the filter tube 1 through the transition metal hose 8.
[0024] It should be noted that the utility model is a universal filter device for water supply, drainage and heating. When in use, the universal filter device for water supply, drainage and heating is first connected to the water supply pipeline of the HVAC equipment, one end of the filter tube 1 close to the valve 2 is connected to the water supply pipeline, and the other end of the filter tube 1 is connected to the water inlet of the HVAC equipment;
[0025] After the installation of the universal filter device for water supply, drainage and heating is completed, water flows into the filter tube 1 through the water supply pipe and is filtered by the filter frame 4. The foreign matter intercepted after filtration follows part of the water flow through the locking head 5 and enters the collection tube 701 of the collection assembly 7, and the other part of the water flow continues to flow through the filter tube 1 to the HVAC equipment;
[0026] After the foreign matter and water flow enter the collection pipe 701, the foreign matter is intercepted by the vertical filter screen 702, and the water flow passes through the vertical filter screen 702 and flows back to the filter pipe 1 through the transfer metal hose 8;
[0027] After closing the valve 2, the filter frame 4 is pulled out for easy cleaning and replacement of the filter frame 4. At the same time, after loosening the locking threaded sleeve 6, the locking head 5 is opened, and the collecting assembly 7 is removed to separate the collecting tube 701 from the locking head 5, so as to facilitate pouring out the foreign matter in the collecting tube 701 and cleaning the foreign matter after filtration and interception. After cleaning, the top end of the collecting tube 701 is reinserted into the locking head 5, and the locking threaded sleeve 6 is tightened again to make the locking head 5 close and clamp the collecting tube 701.
