The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See Fig. 1-4, water supply device capable of controlling water level accurately described in the utility model is made up of water tank 2, altitude valve assembly, water inlet pipe 1, outlet pipe.The upper and lower water inlet pipe 1 and the outlet pipe of connecting respectively of water tank 2, the altitude valve assembly is contained in the water tank 2, and it comprises valve pocket, seal gasket 33, packing ring, pad, fore-set 39, fore-set hold-down arm 37, briquetting 8, floating drum 4.Valve pocket is made of epicoele cover 31 and cavity of resorption cover 36, and the epicoele cover connects with the cavity of resorption external threading, and the top of epicoele cover has water inlet, and water inlet pipe 1 inserts valve pocket from this hole, and the sidewall of epicoele cover 31 evenly is provided with a plurality of discharge outlet 30.The bottom of cavity of resorption cover 36 has groove 35, the bottom of cavity of resorption cover is provided with the mounting platform 34 of packing ring and pad, a cylinder 32 is stretched out in the bottom of cavity of resorption cover, the centre bore of seal gasket 33 is enclosed within on the bottom cylinder 32 of cavity of resorption cover, centre bore and cylinder 32 are with matched in clearance, the water that enters in the valve pocket from water inlet pipe 1 flows in the working chamber that bottom and cavity of resorption cover by seal gasket surround from the gap of 32 on centre bore and cylinder, seal gasket 33 is the ageing-resistant of food-grade requirement, wear-resisting silica gel material makes, its structure cutaway view is referring to Fig. 5, one metal washer and a metallic gasket are housed on the outer rim of seal gasket 33, prevent that seal gasket deflection under the hydraulic pressure effect is too big.See Fig. 4, in the bottom of cavity of resorption cover relief hole 7 is arranged, relief hole 7 belows are provided with briquetting 8, and briquetting 8 is in fore-set 39, and fore-set 39 is fixedlyed connected with floating drum 4.See Fig. 3, the fixing hold-down arm 37 of fore-set under cavity of resorption cover, hold-down arm is made up of upper and lower plate, and upper and lower plate pivots in the left side and connects, and curves a spacing platform 38 in the hold-down arm upper plate is downward, and the hold-down arm lower plate rides on the platform 38.Have circular hole on the upper and lower plate correspondence position of hold-down arm, wherein the circular hole aperture of upper plate is greater than the circular hole of lower plate, the top external diameter of fore-set 39 makes the top of fore-set 39 be clipped between the hold-down arm upper and lower plates greater than lower outer diameter, and the bottom of fore-set 39 is passed the hold-down arm lower plate and is fixed on the floating drum 4.
Fig. 6-9 is the structural representation of this described water supply device capable of controlling water level accurately to water level water inlet control.Water yield liquid level in water tank 2 descends, floating drum 4 fore-set 39 of ining succession drops to lower position (this moment hold-down arm lower plate ride on the spacing platform 38 of upper plate), briquetting 8 leaves relief hole 7, water in the working chamber flows to water tank from relief hole, seal gasket 33 is to bottom offset, and away from water inlet pipe mouth, the water of water inlet pipe injects valve pocket inside, discharge outlet 30 from the epicoele cover enters in the water tank 2 on the one hand, enters in the water tank 2 from relief hole 7 on the other hand.When the water level of boiling water generating means rose to the control metal line of system, water level rose in the water tank, and the air pressure at floating drum top strengthens and floating drum is up pushed away, and moves on the fore-set 39, and briquetting 8 roof pressures are on the aperture of relief hole 7.Seal gasket 33 is in valve pocket, its top and bottom all are subjected to the effect of hydraulic pressure, as Fig. 8 and shown in Figure 9, the hydraulic pressure area of seal gasket 33 bottom surfaces (12) is greater than the hydraulic pressure area of upper plane (11), and the hydraulic pressure area of its upper plane 11 is greater than the outer warp of water inlet pipe 1, surround the working chamber that seal gasket is closed water inlet pipe by seal gasket bottom 12 and cavity of resorption cover 36, when relief hole 7 is closed, water in the working chamber to the pressure of seal gasket 33 greater than the pressure of the water in the epicoele cover 31 to seal gasket 33, seal gasket 33 upwards is moved to upper limit position, closes water inlet pipe mouth this moment.
Figure 10 is applied in the electric water boiler structural representation for the utility model, the boiling water generating means of electric water boiler is communicated with the water side of water tank 2, when boiler is worked, after boiling water flows out, the liquid level of boiling water generating means descends, A represents the liquid level control line of boiling water generating means, when B is illustrated in into the water state, flow to the glide path of the water of boiling water generating means from water inlet pipe, shown in Figure 10 is the core component of electric water boiler, and the structural representation of boiling water generating means and water level control system is as shown in the drawing, in the boiling water generating means, be arranged side by side many heating pipes 5, all heating pipes all are that the bottom is communicated with, and the heating pipe also is communicated with water level control system, therefore, waiting under the air pressure conditions, respectively the water level in the water tank of heating pipe side by side and water level control system is contour.See Figure 10, each heating pipe's 5 upper end position is that height arranges that its lowest position is established the charge for remittance mouth and communicated with the outlet conduit of boiling water generating means, and such layout makes boiling water successively be spilled over to the charge for remittance mouth, there is not the situation of arrheaing, makes boiler can export boiling water continuously.Specifically be the highest away from heating pipe's delivery port position of charge for remittance mouth, near more from the charge for remittance mouth, then heating pipe's delivery port is low more.Heating pipe 5 outer wall evenly is provided with multistage Electric radiant Heating Film 9, and when heating pipe 5 Electric radiant Heating Film 9 energising work, Electric radiant Heating Film 9 is immediately to the heating of the water in managing, make its boiled boiling, boiling water after each pipe boiling overflows, and flow to the charge for remittance mouth from high to low, discharges electric water boiler from the charge for remittance mouth again.Be provided with water vapour recover 6 at the top of boiling water generating means, control in the waterworks from water vapour recover 6 channelling roads water level described in the utility model from the water vapour that heating pipe's 5 boilings are overflowed, steam carries out heat exchange by the discharge outlet 30 that the epicoele of this device overlaps 31 sidewalls, both reached the recovering effect of steam, also can carry out preliminary preheating, improve utilization efficiency of energy current.During this time, heating pipe's material is selected the quartz glass tube of high temperature resistance and high strength.
As another embodiment, the briquetting 8 in fore-set 39 can replace with thimble, and thimble is fixed on the top of fore-set 39, thimble is conical, and the central lines of the center line of thimble and relief hole 7 is when moving on the fore-set 39, thimble is seen Fig. 7 to relief hole 7 sealings.In addition, floating drum 4 also can replace with ball float.
The utility model is with design cleverly, utilize the principle of linker, make the displacement of floating drum and heating pipe's 5 height of water level synchronous, displacement by floating drum promotes the relief hole that fore-set 39 is closed the altitude valve assembly, impel the pressure of the hydraulic pressure that is subjected to of seal gasket bottom greater than top, and in valve pocket, upwards move, close water inlet pipe.The product of using the utility model design can be realized microminiature, ultra-thin effect, save raw material greatly, reduced cost, and the reliability of products height, can be widely used on the product that to control water level as boiler, water dispenser etc., have the huge social economic benefit.
