Embodiment
According to accompanying drawing the embodiment of the utility model is done a detailed explanation below.
According to shown in Figure 1, the described a kind of one-way valve that has rapid pipe joint of present embodiment includes the housing 1 of tubulose; Housing 1 one ends are water intake 101; The other end is a water outlet 103, is provided with the valve plate 102 of central opening in the housing 1 near an end of water intake 101, and valve plate 102 is provided with the valve head 9 that stops fluid to flow to water intake from water outlet near water outlet 103 1 ends; Valve head 9 is provided with positioning plate 8 near water outlet 103 1 ends; Be connected with on the positioning plate 8 along the axial valve rod 6 of housing 1, be arranged with spring 7 on the valve rod 6, also be provided with the fixed block 5 that supplies valve rod 6 the other ends to pass and prop up spring 7 in the described housing 1; Described water outlet 103 1 ends also are provided with rapid pipe joint; Described rapid pipe joint includes tube end 13, seal ring 12, circular mounting 10 and snap close 11; Seal ring 12 is installed in tube end 13 inboards, and the mouth of pipe of tube end 13 is anticreep mouths 131 that internal diameter dwindles from the inside to the outside; Circular mounting 10 is installed on the anticreep mouth 131, and promptly the outer ends of circular mounting 10 is in anticreep mouth 131 outsides, and inner end extends anticreep mouth 131 inboards; Circular mounting 10 the inners are provided with a plurality of arc dops corresponding with anticreep mouth 131, and a plurality of arc dops are in the anticreep mouth 131 to deviate from, and the madial wall of arc dop is provided with the metal card article; Snap close 11 is in anticreep mouth 131 outsides and is stuck in the outer end of circular mounting 10.
This one-way valve generally is used to be connected the pure water outlet of RO membrane cartridge bottle, and in the tank pressure arrival setting value of water purification machine, high-voltage switch gear prevents that the water of pressure bucket from completely blowing back into the RO film when breaking off.
