working principle
While having water in water pipe, now tapered plug 5 is opened, and the brace 17 that vertically slides is mentioned (leaving wedge hole), and rotating shaft 19 can be realized normal with water function; When rotating shaft is in pass water level, put, ceramic valve core I 9 and ceramic valve core II 8 are in closed condition, now in water pipe, there is no water, and water can not there are flowing out waste yet again.
When rotating shaft is in boiling water position, be that ceramic valve core I 9 and ceramic valve core II 8 are in opening state, now in water pipe, do not had water, tapered plug 5 moves right and seals cone shape hole 301 under the restoring force effect of crossed strip 2, simultaneously vertical slip brace 17 is because bottom does not have Water Pressure, down sliding under himself gravity and uprighting spring 15 restoring force actings in conjunction, falls into the wedge shape inclined hole of horizontal slide blocks 16, thereby pins horizontal slide blocks 16.In pipe during water, because ceramic valve core I 9 and ceramic valve core II 8 are also in opening state, water enters the cavity I in valve core, but tapered plug 5 now still clogs cone shape hole 301, does not have water to outflow, and can not cause and waste water.
Want water, ceramic valve core I 9 and ceramic valve core II 8 need to be shut, brace 17 bottoms of vertically sliding are subject to huge Water Pressure and move up, and convex surface skids off the wedge shape inclined hole of horizontal slide blocks 16, removes skidding off the locking state of horizontal slide blocks 16, now again that ceramic valve core I 9 and ceramic valve core II 8 is open-minded, water flows to cavity I, and because horizontal slide blocks 16 is not lockable, tapered plug 5 is subject to huge Water Pressure, can be pushed out cone shape hole and form path, can normal water.
