[0002] A valve is a device used to control the flow of gases, liquids, gases or liquids containing solid powders in various pipelines and equipment. With the continuous development of R&D technology, the functions and types of valves are also constantly being improved and updated. The existing CNC heat network valve is used in areas where hot water or cold water is the controlled medium. The intelligent actuator controls the water supply through the equipment. During use, in order to improve the quality of water flow, a filter is usually provided to filter the water source passing through.

[0003] For example, the CNC heat network valve with application number CN202223458874.0 includes a valve body, a first flange, a hollow groove, a long groove, a filter and a block. After the valve body is connected to the external water pipe through the first flange, when the water source passes through the valve body and the top pipe, the filter can be used to filter a certain amount of calcium ions and magnesium ions.

[0004] The filter in the above patent is limitedly installed on the circumferential inner wall of the first valve body, and a certain amount of calcium ions and magnesium ions in the water are filtered through the filter. The filtered calcium ions and magnesium ions are attached to one side of the filter. The long-term attachment of calcium ions and magnesium ions will form scale, which will cause blockage of the filter mouth. When the operator cleans the filter, he needs to disassemble a set of installed flanges first, and then he can take out and clean the filter placed on the circumferential inner wall of the valve, which is more troublesome.

[0005] Therefore, we proposed a digitally controlled hot network valve with filtering and anti-clogging functions to solve the above problems. Utility Model Content

[0028] The filter assembly 33 includes a filter mesh block 331 and an extension block 332 fixedly installed in the middle of the upper end of the filter mesh block 331. The filter mesh block 331 is placed in the middle of the inner cavity of the hollow circular ring 311 to filter the water flowing through.

[0029] A sealing arc block 333 is fixedly installed on the upper end of the extension block 332 , and the filter screen block 331 drives the extension block 332 to be movably installed in the inner cavity of the circular embedding groove 312 and the connecting groove 313 .

[0030] A fitting plate 334 is fixedly installed on the upper end of the sealing arc block 333. The sealing arc block 333 is set at the upper end of the inner cavity of the connecting groove 313 for sealing.

[0031] In this embodiment: when the operator needs to remove the filter screen block 331 for cleaning, the operator first rotates the hollow round block 41 threadedly connected to one end of the outer surface of the external double-threaded pipe 1 to move the hollow round block 41 out from the outer surface of the support mechanism 31, and uses a screwdriver to remove the screws fixed in the inner cavity of the fixing groove 335, and pulls the fitting plate 334 to drive the sealing arc block 333, the extension block 332 and the filter screen block 331 to withdraw from the inner cavity of the circular embedding groove 312 and the connecting groove 313, and then takes out the filter screen block 331.
