Description
Technical field
The present invention relates to the automatic control of liquid technical field, relate in particular to a kind of float-controlled valve, this float-controlled valve is mainly used on the special water purifier for drinking machine, and the water level in the control drinking machine bucket also can be used for other similar occasion.
Background technique
The float-controlled valve of control drinking machine bucket middle water level in the special water purifier for drinking machine, the structure of known technology as shown in figure 11, it comprises float 18, flap 19, nut 20, conical gasket 21 and valve body 25; Conical gasket 21 fixedly is assemblied on the flap 19, flap 19 is fixed assembling with float 18 again, valve body 25 is provided with ostium excurrens 26, assembly parts easy on and off motion within the specific limits after float 18, flap 19 and conical gasket 21 assemblings, effect that 25 pairs of flaps 19 of nut 20 and valve body have spacing (or guiding), valve body 25 sealing and fixing are in the bottom of following barrel 22 of special water purifier for drinking machine, and float is suspended in the drinking machine bucket 17.
When the user when drinking machine is fetched water, the water level in the bucket 17 can descend thereupon, so float also descends thereupon, conical gasket 21 will leave ostium excurrens 26, float-controlled valve is opened, the water in following barrel 22 of the special water purifier for drinking machine will flow to drinking machine bucket 17; When the user stops to fetch water, the water in the following bucket 22 will continue to flow to drinking machine bucket 17, so the water level in the bucket 17 will rise gradually, float 18 also rises thereupon; After a period of time, water level rises to when enough high, conical gasket 21 will push up to ostium excurrens 26 under the floating function that float 18 is produced, ostium excurrens 26 is sealed and makes it sealing, at this moment, water in following barrel 22 of the special water purifier for drinking machine will stop to flow to drinking machine bucket 17, thereby the water level in the bucket 17 is controlled.
Yet, above-mentioned float-controlled valve is not at every turn can both be reliable as described above in use, this be because: 1. radially and between valve body 25 or the nut 20 there is the gap in flap 19, place the impossible abswolute level in ground of drinking machine, special water purifier for drinking machine produces inclination-conical gasket 21 when how much also existing certain inclination, these factors all may cause float 18 to rise axis does not overlap with the axis of ostium excurrens 26;
2. more seriously, the current that flow out from ostium excurrens 26 flow through from the upper surface of float 18, and in a single day small skew appears in float 18, and these current will mainly flow through from the lower zone of float 18 upper surfaces, make float 18 tilt more, and make float 18 keep heeling condition to rise.
The float 18 of heeling condition can not guarantee that the normal incidence top is to ostium excurrens 26 in the conical gasket 21, and this just certainly will cause float-controlled valve to leak water level Control Failure (Figure 12).
In order to improve the sealing reliability (sealing reliability) of float-controlled valve, common improvement way is to strengthen the guide function of float-controlled valve, and its specific practice is lengthening guiding length and reduces the guiding clearance.After guiding length lengthening and guiding clearance reduce, can guarantee that conical gasket 21 can both middle normal incidence push up to ostium excurrens 26 at every turn.Through such improvement, the sealing good reliability picture of float-controlled valve should be no problem, yet actual conditions are really not so.Because absolute pure water is non-existent, even how many purified water also exists certain impurity, in addition, airborne tiny dust also can enter in the water, and these micro-impurity will gather in the guiding clearance, accumulate over a long period, cumulative, it is dumb to cause flap 19 to move up and down at last, even stuck, finally causes the float-controlled valve sealing unreliable.This flap 19 that causes owing to impurity in the water dumb unreliable problem of float-controlled valve sealing that produces that moves up and down,, guiding clearance less float-controlled valve long for guiding length, situation is even more serious.
To sum up, the float-controlled valve that is used to control drinking machine bucket middle water level on the special water purifier for drinking machine also has further improved necessity.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of float-controlled valve at the deficiency of above-mentioned prior art present situation, and this float-controlled valve is mainly used on the special water purifier for drinking machine, and the water level in the control drinking machine bucket also can be used for other similar occasion.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: a kind of float-controlled valve, and it comprises float, valve body, flap, conical gasket, guiding (or spacing) mechanism; Conical gasket fixedly is assemblied on the flap, and flap fixedly is assemblied on the float, and valve body is provided with ostium excurrens; Guide mechanism has guiding (or spacing) effect to flap, to guarantee that the normal incidence top is to ostium excurrens in the conical gasket energy; Float-controlled valve has the structure that the current that flow out from ostium excurrens do not flow through from the upper surface of float-controlled valve; Valve seal is fixed in the bottom of following barrel of special water purifier for drinking machine, and float is suspended in the drinking machine bucket.
Described float and flap can be two parts independently separately, also can be parts that is integrally combined.
Described guiding (or spacing) mechanism can be the annulus that extends downwards from valve body lower portion, also can be the independent guide elements that is provided with.
The structure that the described current that flow out from ostium excurrens do not flow through from the upper surface of float-controlled valve can have following dual mode to realize:
First kind of mode: float is designed to the cirque structure that the longitudinal section is " ∏ " shape, this structure comprises inner core and urceolus, uncovered between inner core and the urceolus at top seal, bottom, be provided with flow channel in the inner core, this flow channel is lower than the float-controlled valve upper surface, the current that flow out from ostium excurrens do not flow through from the upper surface of float, but flow into the drinking machine bucket through this flow channel.
The second way: anti-current guard shield is set above float, makes the current that from ostium excurrens, flow out flow to the drinking machine bucket, and do not flow through from the upper surface of float through the upper surface of anti-current guard shield.
The current that flow out from ostium excurrens do not flow through from the upper surface of float, and this has just fundamentally eliminated the float tilt problem that causes because of current.
Further technical measures of the present invention are: float inside is provided with water-stop sheet, so that float is separated into the inner chamber that several can independently produce buoyancy, each inner chamber all has the top and sidepiece seals, the uncovered structure in bottom.Float is as small skew (promptly departing from middle positive position) occurring, then the inner chamber of the low side of float will immerse more in the water (promptly drinking water is darker), this inner chamber is relatively large with the buoyancy that produces buoyancy earlier or produced, under this buoyancy function, force the low side of float to be raised, make positive position in the float recovery, promptly float will be ajusted under this floating function automatically.
Float-controlled valve of the present invention, because the horizontal equilibrium of float is not subjected to the influence of float-controlled valve water outlet current, and float has ajusts function automatically, guarantee that the normal incidence top is to the reliability of ostium excurrens thereby greatly raising in the conical gasket, so float-controlled valve can suitably reduce the requirement of guiding, the length that promptly leads can suitably reduce, and the guiding clearance can suitably be strengthened.After guiding length reduces to strengthen with the guiding clearance, the flap that causes owing to impurity in the water dumb unreliable problem of float-controlled valve sealing that produces that moves up and down will greatly be eased.
The beneficial effect of the technology of the present invention is: the float in the float-controlled valve has ajusts function automatically, and to the less demanding of (or spacing) that lead, the sealing reliability of float-controlled valve is greatly improved.
