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 described in the utility model, one end of its valve body 5 connects an end of a piston/ cylinder 8,8 of valve body 5 and piston/cylinders are connected by connecting thread 7, the outer end cap 10 of piston/cylinder 8 is provided with water control interface 9, water control interface 9 is provided with and connects internal thread 11, piston 12 in the piston/cylinder 8 is connected on the piston rod 4,8 of piston 12 and piston/cylinders are gapped, the end cap 13 of valve end is provided with the piston rod hole, 4 in piston rod hole 14 and piston rod are provided with the gap, and the other end of valve body 5 is an inner water tank interface 2, and the inner water tank interface end of valve body is provided with and connects external screw thread 3, be fitted with seal cover 1 on the inner water tank interface 2, the medial surface of seal cover 1 is provided with sealing ring 15, and seal cover 1 is connected the other end of piston rod 4, and a side of valve body 5 is provided with water interface 6 up and down.
As shown in Figure 2, in application in practice, the utility model connects water control pipeline 29 and tap water pipe line 27 by water control interface 9, connect inner water tank 18 by inner water tank interface 2, be threaded, easy to operate, connect three-way pipes 19 by water interface 6 up and down, one the tunnel connects upper and lower conduit road 20, and another road passes to the breather pipe 17 of inner water tank 18 upper air floor.Each control valve in the use, is regulated as required in water control pipeline 29, tap water pipe line 27, upper and lower conduit road 20 and pick and place and be respectively equipped with control valve 28,26,21,24 on the hot water line 23.
Operation principle:
Heat-obtaining water reaches when going up water, open running water control valve 26, water control pipe-line control valve 28, running water enters the inner chamber of piston/cylinder 8 to water control interface 9 by water control pipeline 29, owing to be subjected to the effect of tap water pressure, make on the piston rod 4 after piston 12 is stressed and move, piston 12 is with 14 shutoff of piston rod hole, simultaneously, 1 of seal cover is by jack-up, opens the path of inner water tank 18 and inner water tank interface 2.At this moment, close the control valve 28 of water control pipeline 29, seal cover 1 still is in by the jack-up position.Pick and place hot water as needs, close running water control valve 26, open upper and lower conduit road control valve 21, the hot water in the inner water tank 18 will flow out by upper and lower conduit road 20, thereby can obtain hot water from tap 25 and shower water tap 22; As water on the need, open running water control valve 26 and upper and lower conduit road control valve 21, just can inject cold water through upper and lower conduit road 20 to inner water tank 18; Use when needing emptying in the winter time, running water control valve 26 is closed, fetch boiling water leading 25, water control pipe-line control valve 28 and upper and lower conduit road control valve 21, because upper and lower conduit road 20 communicates by the air layer of three-way pipe 19 with inner water tank top, water emptying rapidly in water in the upper and lower conduit road 20 and the water control pipeline 29, simultaneously, seal cover 1 falls because of the active force that has lost running water, cut off the path of inner water tank 18 and the utility model inner water tank interface 2, hot water in the inner water tank 18 is in hold mode, upper and lower conduit road 20 and water control pipeline 29 all are in emptying state, have reached the purpose of evacuation and anti-freezing.
As shown in Figure 3, structure is identical with embodiment 1 basically with operation principle, has just set up ventilation interface 30 in a side of valve body, with its breather pipe that directly passes to inner water tank upper air layer, is used for emptying.
