In the present embodiment, exhalant canal 105 adopts the water-out manners in two water outlet water route, adopts water to carry out shutoff air, avoids bubble noise.Simultaneously by the changes of section in main water route 101, reduce water flow, current are slowed down, and when fed water has a high pressure, current expired main water route 101, and the current overflow through slowing down enters secondary water route 102, realizes muting function.
Embodiment 2
The water inlet valve body of a kind of overflow-type low noise as shown in Figure 15, Figure 16, comprise inlet valve main body 100, inlet pipeline 200, inlet pipeline 200 is connected with inlet valve main body 100, for inlet valve main body 100 supplies water.Inlet valve main body 100 offers atmosphere entry 400 in the position higher than inlet valve highest water level, and the liquid level in inlet valve leads directly to air by atmosphere entry 400, for realizing anti-siphon; The exhalant canal 105 of inlet valve comprises main water route 101, some secondary water routes 102, main water route 101 is directly communicated with intake tunnel 103, secondary water route 102 is communicated with main water route 101, the water flow in main water route 101 is less than the flow of inlet water of intake tunnel 103, and current overflow to secondary water route 102 and carry out auxiliary water outlet from main water route 101.
As shown in Figure 17, Figure 18, inlet valve main body 100 includes water pipe 104, exhalant canal 105, intake tunnel 103, exhalant canal 105 is sleeved on outside water inlet pipe 104, and the water intake 106 of intake tunnel 103 is opened on main water route 101, and secondary water route 102 is sleeved on outside main water route 101.In the present embodiment, the current that water inlet pipe 104 enters inject intake tunnel 103 from the outlet on water inlet pipe 104 top, after water flow control mechanism 500, flow into exhalant canal 105 from water outlet.
In the present embodiment, secondary water route 102 and the connecting port 113 in main water route 101 are arranged on the top in main water route 101, and current expired main water route 101, flowed to secondary water route 102 from top, main water route 101.Namely secondary water route 102 is nested in periphery, main water route 101, and connecting port 113 is the space that Shang Yufu water route, top, main water route 101 102 communicates.After current fill main water route 101, diffuse out from top, main water route 101, flow into secondary water route 102 from connecting port 113.
In order to prevent the water inlet of water outlet water impact fast valve body, produce noise and splash, the opening in main water route 101 is folding double layer construction, and form the intake chamber 114 that Open Side Down, the water intake 106 of intake tunnel 103 is arranged in the scope of intake chamber 114.Current cushion through intake chamber 114, flow into main water route 101, slow down water flow along intake chamber 114.
In the present embodiment, atmosphere entry 400 is arranged on the end face of inlet valve main body 100.If directly by the opened top of inlet valve main body 100, conveniently produce assembling, but atmosphere entry 400 is excessive, easily there is the situation of current splash, and if atmosphere entry 400 is too little, inlet valve main body 100 is made of one formula structure, assembling is produced in impact again.Cross to prevent atmosphere entry 400 excessive, or the problems such as Assembling Production difficulty is large, in the present embodiment, as atmosphere entry 400 is arranged in upper cover 107 by Figure 19, Figure 20, Figure 21, inlet valve main body 100 opened top, upper cover 107 is buckled in inlet valve main body 100 end face.
In order to reduce the water flow in main water route 101 further, the lower ending opening 111 in main water route 101 is less than the upper end open 112 in main water route 101.In the present embodiment, the inner surface wall 115 inwardly undergauge of inlet pipeline 200, reduces lower ending opening 111 size in main water route 101.
In the present embodiment, exhalant canal 105 adopts two water routes water-out manners, swiftly flowing current are flow to water-filled main water route 101,101 pairs, main water route flow velocity produces larger buffering, reduce the water flow velocity on aqueous vapor border, realize muting function by the water flow velocity reducing aqueous vapor border, make greatly to reduce into water sound.When the water flow pressure that intake tunnel 103 flows out is larger, flow is comparatively large, and the lower ending opening 111 in main water route 101 has little time the current of discharging, and is overflowed by secondary water route 102.
Above-described embodiment is only used to the utility model is described, and is not used as restriction of the present utility model.As long as according to technical spirit of the present utility model, change above-described embodiment, modification etc. all will be dropped in the scope of claim of the present utility model.
