The specific embodiment

The utility model is described in further detail in conjunction with the foregoing description accompanying drawing

As shown in Figure 1, solar water heater emptying valve jockey described in the utility model, its jockey bottom has screw thread silk 9 to be connected with emptying valve body 15, jockey inner casing 3 shell walls are provided with through hole 7, jockey inner casing 3 inner chambers have a sealing to cut off 5, and the upper strata 4 of partition is a body to upper open type; Cut off upper strata 4 built-in buoyancy sealing gaskets 10; Buoyancy sealing gasket 10 is connected by floating ball rod 11 with the ball float 37 that places inner water tank, gapped between jockey inner casing 3 and the shell, the uncovered of screw thread silk arranged at the top of shell 2, be inner bag interface 1 connection that is threaded with inner bag, one end of valve body 15 connects an end of a piston/

cylinder

17,17 of valve body 15 and piston/cylinders are connected by screw thread 16, the outer end cap 19 of piston/cylinder 17 is provided with water control interface 18, water control interface 18 is provided with and connects internal thread 20, piston 21 in the piston/cylinder 17 is connected on the

piston rod

14,17 of piston 21 and piston/cylinders are gapped, the other end of valve body 15 is a jockey interface 13, the jockey interface end of valve body is provided with and connects external screw thread 9, be fitted with seal cover 12 on the jockey interface 13, the medial surface of seal cover 12 is provided with sealing gasket, and seal cover 12 is connected the other end of piston rod 14, and a side of valve body 15 is provided with water interface 23 up and down.

As shown in Figure 2: in actual applications, the utility model is by water control interface 18, connect water control pipeline 36 and tap water pipe line 34, connect coupling arrangement inner casing 3 by jockey interface 13, connect inner water tanks 28 by shell 2, it is easy to operate to be threaded, and connects three-way pipes 30 by water interface 23 up and down, one the tunnel connects upper and lower conduit road 31, and there is the breather pipe 27 of the pipeline connection inner water tank 28 upper air floor of check valve 29 on another road by string.Water control pipeline 36, tap water pipe line 34, upper and lower conduit road 31 are respectively equipped with control valve 35 and mixed water valve 32, in the use, regulate getting final product as required.

Operation principle

Heat-obtaining water reaches when going up water, open running water control valve 35, running water enters the inner chamber of piston/cylinder 17 to water control interface 18 by water control pipeline 36, owing to be subjected to the effect of tap water pressure, make on the piston rod 14 after piston 21 is stressed and move, piston 21 is with 24 shutoff of piston rod hole, simultaneously 12 of seal covers are by jack-up, open the path of jockey interface 13 and jockey inner casing 3, through hole 7 by shell side wall in the jockey is communicated to shell 2 and jockey inner casing 3 gaps, to inner bag interface 1, joining water box inner bag 28, pick and place hot water as needs, open the mixed water valve 32 on upper and lower conduit road, the hot water of inner water tank 28 will flow out by upper and lower conduit road 31, thereby can obtain hot water from shower water tap 33, as water on the need, open running water control valve 35 and upper and lower conduit road and mix water valve 32, through upper and lower conduit road 31, can inject cold water to inner water tank 28 along above-mentioned path, when cold water reaches certain water level, because the effect of ball float 37, drive on the buoyancy sealing gasket 10 and move, reach automatic loading water until with 1 shutoff of inner bag interface, the purpose of the full automatic stop of water.Because the effect of check valve 29, cold water can be by this path to inner water tank 28 during last water.

When needing emptying in the winter time, running water control valve 35 is closed, open the upper and lower conduit road and mix water valve 32, put to mixing water level, because upper and lower conduit road 31 communicates with inner water tank upper air floor by three-way pipe 30, water emptying rapidly in water in the upper and lower conduit road 31 and the water control pipeline 36, seal cover 12 falls because of the effect that loses tap water pressure simultaneously, the path that cuts off inner water tank 28 and the utility model jockey interface 13, hot water in the inner water tank 28 is in hold mode, upper and lower conduit road 31 and water control pipeline 36 all are in emptying state, have reached the purpose of evacuation and anti-freezing.
