Describe a preferred embodiment of the present utility model below with reference to accompanying drawings in detail.
Fig. 1 is the sectional view of a preferred embodiment of the water feed apparatus of the automatic control water level of the utility model.
Referring to accompanying drawing, the water feed apparatus of this automatic control water level is made of a float-controlled valve 1 connected to one another, a hydraulic pressure conduit 2 and a water intaking valve 3.Float-controlled valve 1 has the float valve body 11 of a upper end open, and the bottom of this valve body has the inlet 16 that a feed tank water flows into, and it links to each other with a water tank 4 by a pipe 17.The upper end of float valve body 11 is connected with the end flange of a little hydraulic pressure cylinder body 12.Little hydraulic pressure cylinder body 12 is inverted T shape, and its end flange limits a float cavity with float valve body 11, and the inside holds a float 13 moving up and down.Little hydraulic pressure cylinder body 12 has an endoporus that runs through, and holds a valve piston 14 in the endoporus slidably, the lower end of this valve piston project into can with float 13 contacted positions.The medium position place of valve piston 14 is provided with an O-ring seals 15, to prevent the mistake of letting out of water pressure.
The upper end of little hydraulic pressure cylinder body 12 is connected with an end of hydraulic pressure conduit 2 by methods such as welding.Be full of water or other liquid in the conduit 2, with the hydraulic pressure transfer of realizable force.The other end of hydraulic pressure conduit 2 is connected in water intaking valve 3.Water intaking valve 3 has a diaphragm valve 19, and this diaphragm valve 19 comprises a barrier film valve body 20.Barrier film valve body 20 has the water supply outlet 22 that a water source inlet 21 and that communicates with the water source communicates with water tank 4.21 places that enter the mouth, water source are provided with a filter screen 33, are used for the impurity of elimination water.Be provided with members such as barrier film pressing plate 23, barrier film 24 and spool 25 in the valve body 20.Valve body 20 is connected with a barrier film valve gap 26 by bolt, thus the inner chamber of sealing diaphragm valve 19.Be connected with a big hydraulic cylinder body 28 that is elongate by nut 27 on the barrier film valve gap 26, cylinder body has an endoporus that runs through, and holds a big piston 29 in the endoporus slidably.The left end of big piston 29 stretches in the diaphragm valve 19 by a through hole in the barrier film valve gap 26, and engages with the right side of spool 25.One compression spring 30 is sheathed on this big piston 29, is used for when hydraulic pressure removes big piston 29 being pushed away to the right and it being resetted.In hydraulic pressure cylinder body 28 He in the barrier film valve gap 26, be provided with an O-ring seals 30 and 32 respectively on the piston 29, be used for passing through of anti-sealing.
During use, the float-controlled valve of this water feed apparatus 1 links to each other with water tank 4 by pipe 17, and the water source inlet of diaphragm valve 21 links to each other with the water source, and water supply exports 22 and communicates with water tank 4.When the water in the water tank 4 does not reach the water level of being controlled, when just the water level in the float valve body 11 does not reach certain altitude, float 13 drops on the bottom of float valve body 11, thereby the spring in the water intaking valve 3 30 jack-up big piston 29 easily, make the barrier film 24 in the diaphragm valve 19 be in the enable possition, allow the inflow of water into water tank 4.As traditional diaphragm valve, barrier film 24 left and right chambeies all are communicated with current, and no matter source pressure is much, but the pressure balance of barrier film 24 and arranged on left and right sides, and this feasible promotion spool 25 is closed barrier film 24 required power can be very little.When the water level in the water tank 4 raise and make water in pipe 17 inflow float valve bodies 11, float 13 was floated.The buoyancy gradually big deeply and gradually with float 13 submergences produces hydraulic pressure on valve piston 14, hydraulic pressure is passed to big piston 29 through hydraulic pressure conduit 2.According to the Basque theorem, the ratio of the buoyancy that the thrust that big piston produced and valve piston are suffered is the ratio of the diameter square of large and small piston, thereby pressure is amplified.The power of this amplification is enough to close water intaking valve and stops to supply water.But during water tank 4 waters, water level falls, the float-controlled valve dehydration, and then valve piston 13 loss of buoyance supporting, and displacement space has been arranged.Because hydraulic pressure conduit 17 seals, the motion of valve piston 13 under action of gravity produces pull of vacuum, and the elasticity of spring 30 and barrier film 24 all acts on the big piston 29, realizes the automatic water supplement function so can open water intaking valve easily.
