[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2As shown, this static balancing valve includes a valve body 3 with an inlet 1 and an outlet 2. A flow pipe 4 for water supply is provided inside the valve body 3. A detection component 5 for detecting the liquid state is provided on the valve body 3 and relative to the flow pipe 4. A valve cover 6 is provided on the valve body 3. A valve core 7 and a valve stem 8 are provided inside a connecting sleeve. A handwheel assembly 9 for controlling the rotation of the valve stem 8 is provided on the valve body 3. The valve core 7 is fixedly mounted on the valve stem 8. A filter screen 10 is provided at the inlet 1. A mounting part 11 is provided on the inner wall of the valve body 3 relative to the inlet 1. A connecting post 12 is provided on the mounting part 11. A connecting hole 13 is provided on the filter screen 10 for the connecting post 12 to pass through. A snap-fit ​​mechanism 14 is symmetrically provided on the connecting post 12. 4. The activity space 15 for the operation is provided. The snap-fit ​​mechanism 14 includes a snap-fit ​​spring 16 and a snap-fit ​​block 17. When disassembling or assembling, the snap-fit ​​block 17 can be pressed into the activity space 15, allowing the snap-fit ​​mechanism 14 to release its constraint on the filter screen 10, thus enabling the filter screen 10 to be quickly disassembled and assembled for easy cleaning. The filter screen 10 is provided with a mounting post 18, and a magnet 19 is provided on the mounting post 18. The filter screen 10 is provided with a detachable adsorption cover 20 to protect the mounting post 18. When water flows through the filter screen 10, the magnet 19 will adsorb iron-containing impurities in the water onto the adsorption cover 20. When cleaning later, the adsorption cover 20 can be removed, and the iron-containing impurities can be easily rinsed away with water after losing the adsorption force of the magnet 19, making subsequent cleaning convenient.

[0016] To elaborate further, the detection assembly 5 consists of two detection elements 21. The detection element 21 includes a sealing plug 22, a plug 23, and a test head 24. The valve body 3 has two openings 25 for connecting the detection elements 21. The test head 24 is fixedly installed on the openings 25 of the valve body 3.

[0017] To elaborate further, the valve core 7 has a plug head 26 at its front end, and the front end of the plug head 26 is circular.
