By adopting technique scheme, structure arranges rationally, and switch axle covers out dirty passage and valve body drain outlet, and sewage just around filters through filter screen, and the dirt filtering down is stayed dirt through filter screen drain outlet in foreign material storing cavity, so just complete filtration; When switch axle is opened out dirty passage and valve body drain outlet, sewage just completes blowdown through going out dirty passage and valve body drain outlet.
The utility model is further set to: position, the corresponding valve body drain outlet of described switch axle front end offers pollution discharge groove, described pollution discharge groove goes out dirty channel setting and has connecting passage near going out the wall correspondence of dirty passage, uses dirty passage, connecting passage, pollution discharge groove, valve body drain outlet be communicated with and realize automatic pollution discharge by rotary switch axle.By this setting, switch axle structure arranges rationally, is communicated with or cuts off dirty passage and valve body drain outlet is easy to operate.
The utility model is also further set to: described pollution discharge groove is rectangle groove.By this setting, described pollution discharge groove structure arranges rationally, and rectangle groove blowdown is more smooth and easy, and efficiency is high.
The utility model is also further set to: between described switch axle two ends and valve interior wall face, be provided with several O RunddichtringOs.By this setting, switch axle and valve seal are good.
The utility model is also further set to: described switch axle rear end is socketed with gland, and described gland and valve rear end clamping.By this setting, gland can prevent that dust from entering switch axle front end, makes work more reliable.
The utility model is also further set to: described switch axle ear end face exposes gland, and switch axle rear end is provided with handle, and described handle is connected and fixed by screw and switch axle ear end face.By this setting, in switch axle outer end, handle is set, more convenient to operate.
The utility model has the advantages that: compared with prior art, the utility model structure arranges rationally, switch axle covers out dirty passage and valve body drain outlet, sewage just around filters through filter screen, and the dirt filtering down is stayed dirt through filter screen drain outlet in foreign material storing cavity, so just complete filtration; When switch axle is opened out dirty passage and valve body drain outlet, sewage just completes blowdown through going out dirty passage and valve body drain outlet.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Brief description of the drawings
