Equipped with sealing ring 5, the valve body 1 is equipped with filter mechanism 6, and the filter mechanism 6 includes the first filtering layer 61, the second filtering layer successively
62 and third filtering layer 63, first filtering layer 61 is with magnetic metal mesh, and the second filtering layer 62 includes first chamber 621 and the
Two chambers 622, are equipped with water-supply-pipe 64 between the first chamber 621 and second chamber 622, the wherein sealing of first chamber 621 is set
It sets, first chamber 621 is equipped with apopore 623, and water-supply-pipe 64 is connected with pump 8, and the water of second chamber 622 is conveyed by pump 8
It sprays or overflows to first chamber 621, and then from apopore 623, water enters second chamber 622, so recycles, to flowing through
Gas washed, the dust particle being wherein mingled with is filtered, second chamber 622 is equipped with water inlet, third filtering layer 63 and the
One filtering layer 61 is placed in right over water inlet, is fallen into second chamber 622 convenient for the particulate matter on the first filtering layer 61 and third
Liquid or impurity in filtering layer 63 are fallen into second chamber 622, are directly incorporated in water, prevent that secondary pollution occurs to gas,
It is convenient to clean simultaneously.When installation, first chamber 621 is placed in top, and second chamber 622 is located at lower section, prevents water therein from flowing out；
