Since the present invention adopt floating block be enclosed within valve shell top and with the valve shell matched in clearance, between spool and valve shell spring is housed, the structure that spool and valve shell are slidingly matched; After water acquires a certain degree; Make the floating block levitating, open inlet channel, gas gets in the cavity of spool and valve shell formation; Gas pressure overcomes the elastic force acting and pushes spool, and water is discharged from the bottom of cup through hole.After having arranged water, floating block is fallen by gravity effect, seals the inlet channel that gets into cup, and valve core cavity air pressure reduces, and back-moving spring makes valve core reset, closes drainage channel and prevents that extraneous air from getting in the cup from drainage channel.Therefore, the present invention can carry out draining under the state that does not stop air feed, air feed and draining are carried out synchronously, does not disturb mutually, has improved the effect of saving oneself.
Description of drawings
Fig. 1 is a structure cutaway view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain, but do not constitute any restriction of the present invention.Shown in Figure 1, the present invention includes cup 1 and bowl cover 2, bowl cover 2 is provided with air inlet and air outlet, cup 1 and 2 movable cooperations of bowl cover, said movable cooperate adopt spin, a kind of in clamping and the inserting mode, also can adopt other movable connection method.Said bowl cover 2 is provided with helical blade 3, and air inlet is to living helical blade 3, the air that makes input with helical blade 3 downwards to around rotation.Said cup 1 bottom is provided with through hole, and this through hole epimere is a circular hole, and hypomere is a bellmouth.Valve shell 6 is spirally connected with cup 1 bottom and is one, also can adopt its mode to fix as one, and the bottom of valve shell 6 is provided with osculum, and the top of valve shell 6 is provided with air admission hole 8.Spool 7 is positioned at valve shell 6, and spool 7 tops and valve shell 6 are slidingly matched, and spool 7 bottoms are cone, and this cone is corresponding with the bellmouth of cup 1 bottom, and spool 7 bottoms are provided with steam vent 9.The upper end of back-moving spring withstands on the outer rim bottom on spool 7 tops, and its lower end withstands on the bottom surface of cup 1.Circularhole diameter in cup 1 bottom through-hole is greater than spool 7 diameters through this circular hole.Floating block 4 be enclosed within valve shell 6 top and with valve shell 6 matched in clearance, floating block 4 tops are provided with vent plug 5, vent plug 5 is provided with passage, vent plug 5 centers are over against air admission hole 8, the diameter in spool 7 base bleed holes 9 is less than the diameter of valve shell 6 top air admission holes 8.
The course of work is following: when static state, stop to supply gas no water in the cup 1; At this moment, floating block 4 is fallen by gravity effect and covers on the valve shell 6, and the vent plug 5 at floating block 4 tops is pressed on the air admission hole 8 at valve shell 6 tops; Shutoff air admission hole 8; Simultaneously, the passage on the vent plug 5 makes the inner chamber of valve shell 6 and the current path shutoff between the cup 1 also by the top shutoff of valve shell 6.Can prevent that so outside contaminated air from getting in the cup 1.Under this state, spool 7 is upwards risen by the effect of spring, and the cone until spool 7 bottoms gets in the bellmouth of cup 1 bottom, and till being close to bellmouth.Though the steam vent 9 of spool 7 bottoms communicates with the external world, outside air can not get in the cup 1.
When supplying gas, treated standard compliant gas gets into from the air inlet of bowl cover 2, and gas gets into after-blow on helical blade 3; Under the effect of helical blade 3; Gas produces rotation, and the aqueous vapor in the gas receives action of centrifugal force to collision of cup 1 inwall and friction, on cup 1 inwall, condenses into water and flows to cup 1 bottom; And flow out at the air outlet on bowl cover 2 under the gas pressure effect on the more frivolous upper strata in cup 1 of dry gas.State when at this moment, miscellaneous part keeps static.After water runs up to certain altitude, floating block 4 is floated, floating block 4 drives vent plug 5 and rises; The no longer shutoff of air admission hole 8 at valve shell 6 tops, and the passage on the vent plug 5 is also no longer by shutoff gets in the cavity that is made up of valve shell 6 and spool 7 than the gas of hyperbar; Because the diameter of steam vent 9 is less than the diameter of air admission hole 8, the air pressure of spool 7 inner chambers rises gradually, and the cavity volume that is made up of valve shell 6 and spool 7 expands; Spool 7 overcomes the elastic force of spring and outwards releases; The cone of spool 7 bottoms forms drainage channel away from the bellmouth of cup 1 bottom, and the ponding in the cup 1 flows out from cup 1 bottom through the osculum on the valve shell 6.After water was discharged to a certain degree, floating block 4 suffered buoyancy reduced, and the gravity of floating block 4 also slowly falls greater than buoyancy; Vent plug 5 is the air admission hole 8 of shutoff spool 7 gradually, and spool 7 internal gas pressures slowly reduce, and spring progressively resets; Prolong the time of draining; Water is drained, block vent plug 5 fully, till spool 7 resets fully until floating block 4.Above process moves in circles, and makes air feed and draining synchronous working, has improved the effect of saving oneself.
