The specific embodiment:

With reference to accompanying drawing, this float-ball type baroswitch comprises the valve body 1 that has intake tunnel 18 and exhalant canal 19, switch module and the Control Component that can open or cut out described intake tunnel and exhalant canal, and Control Component comprises ball float 9 and floating ball rod 8 thereof.Described switch module comprises the elastic switch pad 4 that is arranged at intake tunnel 18 and exhalant canal 19 intersections, is arranged at the pad support 6 on the elastic switch pad, the sealing cap 3 that is arranged at the sleeve 5 between elastic switch pad 4 and the pad support 6 and the edge of elastic switch pad 4 is pressed on valve body 1 inner edge, the pad support is " drawing pin " shape, its nail face 62 is provided with water hole 61, its nail pin 63 runs through elastic switch pad 4, nail pin 63 vertically on, be provided with 2 two water inlet grooves 64; On the adjacent end face of sleeve 5 and pad support 6, be provided with 4 fins 51, the purpose that fin 51 is set is to make between pad support 6 and sleeve 5 upper surfaces and produces the gap, so that produce the passage between connection intake tunnel 18 and the sealing cap 3 inner chamber B; Above sealing cap 3, be provided with the exhaust spilled water hole 11 of holding one's breath, described sealing cap 3 is anchored on it on valve body 1 by end cap 2, floating ball rod 8 is connected for adjustable angle with water level control lever 7, so that adjust the control water level in pond, water level control lever 7 is hinged on the end cap 2 by bearing pin 17, below water level control lever 7, be provided with diaphragm seal 10, diaphragm seal 10 can with described exhaust spilled water hole 11 involution mutually of holding one's breath.

When preventing to cut off the water, tank water backflow pollution water system on described exhalant canal, is provided with flap valve.Flap valve comprise tubular check valve body 12, place " ten " shape support 14 in the tube, be arranged at support the inner gasket seal 13, can with the external activity pipe of support just in the locking plate on the check valve body 12 15 and place support 14 and locking plate 15 between spring 16, the inner of check valve body is provided with external screw thread and can be connected with the exhalant canal 19 of valve body 1, the outer end of check valve body is provided with internal thread, can match with locking plate 15, locking plate 15 is provided with water hole.

The utility model is used when being installed in the pond, its operating principle is: when drawdown ball float 9 also descends thereupon, connecting rod 8 drives water level control lever 7 and does counterclockwise to rotate around bearing pin 17, the exhaust this moment spilled water hole 11 of holding one's breath is opened, the pressure of the cavity B that is made of sealing cap 3 and switch elastomeric pad 4 equates with atmosphere, be the pressure of the interior pressure of cavity B less than hydraulic pressure, under the effect of hydraulic pressure, switch elastomeric pad 4 is lifted, thereby opened the passage of intake tunnel 18 and exhalant canal 19, to the pond water-filling, the water inlet direction is " A ", be that switch is in opening state, simultaneously, a small amount of tap water slowly enters cavity B by water inlet groove 64, releases from the exhaust spilled water hole 11 of holding one's breath, the sluicing direction is that " B is shown in Fig. 2 B.

When the water level in the pond rises and when driving ball float 9 and being raised to certain water surface, connecting rod 8 drives water level control lever 7 and does the clockwise direction rotation around bearing pin 17, push down the exhaust spilled water hole 11 of holding one's breath until diaphragm seal 10 envelopes of water level control lever 7 left surfaces, be that the exhaust spilled water hole 11 of holding one's breath is closed, because the effect of the screen resilience of switch elastomeric pad 4, tap water slowly enters cavity B by water inlet groove 64, pressure until cavity B equates with the hydraulic pressure of tap water, because the pressure of exhalant canal equates with atmospheric pressure, therefore the pressure in the cavity B is greater than atmospheric pressure, switch elastomeric pad 4 is closely attached on the inlet of exhalant canal 19, promptly closed exhalant canal 19, stop to the pond water-filling, promptly switch is in closed condition, shown in Fig. 2 A.

The operating principle of flap valve is: the float-ball type baroswitch is in opening state, and the hydraulic pressure of tap water is during greater than the pressure of spring 16, and gasket seal 13 is opened, to the pond water-filling.Generally speaking, the water in pond is full.After finishing to the pond water-filling; the float-ball type baroswitch is in closed condition; under the effect of spring 16; gasket seal 13 is sealed the exhalant canal of float-ball type baroswitch; when running water system is cut off the water; water in the pond can not flow backwards yet, and can not pollute water system, plays the effect of protection running water system.
