While opening air valve by above-mentioned rotary switch head, it is indoor that gas can enter installation cavity from suction valve doorway, and discharge through gas outlet valve doorway; Owing to silencer element being set at least one place in suction valve doorway and gas outlet valve doorway, gas can carry out noise reduction through silencer element in above-mentioned flow path, realizes the reduction of noise.Wherein, the microcellular structure of above-mentioned silencer element has the effect of noise reduction, filtration and decompression to gas flow; Above-mentioned spool can be controlled the opening and closing of air valve.
In an embodiment, described silencer element is made up of macromolecular material therein.Thereby, be conducive to realize above-mentioned microcellular structure, and then make silencer element can realize silencing function.
In an embodiment, described valve body comprises valve seat and bibcock therein, and bibcock is arranged on valve seat, and this bibcock and valve seat surround described installation chamber, and described suction valve doorway and gas outlet valve doorway are all located on described valve seat.
In an embodiment, described valve seat and bibcock match and are formed with annular groove therein, and described silencer element is cylindric, and this silencer element is arranged in described annular groove, and the gas outlet valve doorway stated, the partial occlusion residence of silencer element.Thereby, can prevent that silencer element from getting loose, make silencer element block more securely suction valve doorway or gas outlet valve doorway.
In an embodiment, described bibcock is provided with port therein, and described rotary switch head stretches out from this port.Thereby rotary switch head also just can stretch out from chamber is installed, thereby just can control by rotation turn switch head the switch of described air valve in outside.
In an embodiment, on described rotary switch head, be provided with knob therein.Thereby, by turning knob driven rotary switch head, can realize the control to air valve opening and closing.
In a word, the beneficial effects of the utility model are: air valve of the present utility model can reduce noise in use, realizes silencing function.
