The water water level autocontrol valve of going up of the present invention; Utilize buoyancy of water, pressure and suction physical property; Rely on the height of regulating water water level on highly automated control water tank of float or the water tower; Solved the single tube problem of water water spill-over stream up and down, existingly gone up water water level autocontrol valve to have a volume little, installed simple and easyly than other; The advantage of stable performance, its structure can be divided into three kinds of patterns and manufacture use: water water level autocontrol valve such as Fig. 3 on water water level autocontrol valve such as Fig. 2, the straight-through valve body formula on water water level autocontrol valve such as Fig. 1, the bend pipe valve body formula on the three way valve formula.

Auxilliary figure explanation: Fig. 1 is a water water level autocontrol valve on the three way valve formula.

Fig. 2 is a water water level autocontrol valve on the bend pipe valve body formula.

Fig. 3 is a water water level autocontrol valve on the straight-through valve body formula.

1 is three way valve among Fig. 1, is called for short valve body in the specification, and 2 is valve block, and 3 is connecting rod, and 4 is float, and 5 is reduction valve, and 6 is porose pad, and 7 is plug, and 8 is permeable hole on the relief valve body, and 9 is spring, and 10 is ball.

Embodiment and working principle: the present invention works in solar water heater and explains, during work with water water level autocontrol valve such as Fig. 1 on the three way valve formula; Insert last water water level autocontrol valve in the solar water heater water tank lower water inlet by the float end, valve body upper end internal thread is spun on the solar water heater inlet interface external thread, the connecting tube at place, water inlet, valve body middle part; When in solar water heater water tank, going up water, current are crossed porose pad 6 through channel flow and are got into reduction valve 5 inside, are flowed out by permeable hole around the reduction valve right part; Water outlet flows into water tank through the solar water heater lower water inlet from the valve body upper end; When water level rises to float certain altitude position, float receives the buoyancy of water drivening rod, valve block rises, during valve block to valve body upper end water shutoff mouth; Water inlet is closed, and stops to go up water; When the outside draining of solar water heater water tank, valve block receives the suction drivening rod of water, and float falls, and water flows out in solar water heater water tank, and is opposite when water (flow) direction and last water.The reduction valve working principle: when water water supply pressure was big on the solar water heater water tank, water flow drives ball right-hand member in relief valve body moved, and spheroid occupies in the reducing valve body than small end flowing water space; Making in the reduction valve becomes an orifice than small end, and restriction can only be passed through by the part current, and hydraulic pressure is big more; The power of water flow drives ball pressuring spring is big more; Ball is big more to the right-hand member mobile range, and it is many more that ball occupies the space of right-hand member smaller portions in the relief valve body, and the current that can pass through are few more; Hydraulic pressure is more little, and water flow drives ball right-hand member smaller part mobile range in relief valve body is more little, and it is few more than the space of small end that ball occupies reduction valve, and the space that current can pass through is big more, and the decompression amplitude is little.Hydraulic pressure or water velocity are basic identical in the time of when hydraulic pressure varies in size, can keeping on the solar water heater water like this; Reach and stablize the hydraulic pressure effect; Do not receive the influence of tap water hydraulic size when making the work of water water level autocontrol valve; Can proper functioning in various hydraulic pressure vary in size environment, reduction valve also can cooperate a shell or ectosome independently to insert pipeline or insert in the miscellaneous equipment other liquid or gas decompression.

Water water level autocontrol valve such as Fig. 2 on the bend pipe valve body formula; Water water level autocontrol valve body has compared the aperture, lower end less on its valve body such as the syphon shape, internal structure and three way valve formula, without plug; Other structural attachment is all identical, and water water level autocontrol valve is identical on working principle and the three way valve formula.

Water water level autocontrol valve such as Fig. 3 on the straight-through valve body formula; Its valve body shape such as straight-run of pipe; Its valve inner structure has been lacked middle aperture than water water level autocontrol valve body on the three way valve formula, quite with middle aperture and internal structure, annex integral body has moved on to position, valve body lower end aperture, and water intake is in the lower end; Inner other annex valve block, connecting rod, float, reduction valve, porose pad are all identical, and water water level autocontrol valve is identical on working principle and the three way valve formula.

In the water water level autocontrol valve, the three way valve formula makes up easily, stable performance, easy to maintenance on above three kinds of valve body structures; Bend pipe valve body formula combination is difficult slightly, and stable performance, maintenance are not too convenient; The combination of straight tube valve body formula is easy, and easy to maintenance, stability is relatively poor.Compare down, preferred implementation is a water water level autocontrol valve on the three way valve formula.
