The valve assembly of described drain valve comprise two ends be enclosed construction tubular body, be arranged on the water outlet of tubular body intermediate portion and be positioned at the water intake that plays balance water inlet effect of water outlet both sides; Respectively be provided with a water yield controlling mechanism in the tubular body inner chamber between left side water intake and water outlet, between right side water intake and the water outlet, fixedly valve block in the water yield controlling mechanism respectively is processed with an axis hole (18) with the center portion of rotating valve block with concentric manner, and around separately axis hole be processed with that quantity equates, the aperture is identical, corresponding water inlet (17) mutually, position; Described rotation valve block is installed in the tubular body inner chamber by the live axle that crosses tubular body, respectively be provided with a horizontal balanced connecting rod at the two ends of described live axle, and two balanced connecting rods respectively are arranged on the two ends of live axle in the mode that is parallel to each other, and lay respectively at the hollow pontoon of tubular body both sides, the counterweight floating drum all is installed in balanced connecting rod by link two ends.
The volume of described hollow pontoon is greater than the volume of counterweight floating drum, but it is identical in quality.In addition, described hollow pontoon adopts the high-strength structure design, it not only can be worked under hyperbaric environment, and can bear the frequent impact power of water, vapour.
Working principle of the present invention is as follows:
Vapour, water enter body cavity from being mixed into hose nozzle, enter again in the valve assembly that tubular valve block cavity is installed, increase along with inflow, water just can enter in the cavity between water yield controlling mechanism and the water intake (at this moment, the fixedly valve block in the water yield controlling mechanism is in closed state with the water inlet of rotating on the valve block with the fit system of mutual dislocation) by left and right water intake.When water level is elevated to hollow pontoon height and position of living in, because hollow pontoon is bigger than counterweight floating drum volume, the suffered buoyancy of hollow pontoon is also just greater than the counterweight floating drum, when inflow reduces, water level descends, hollow pontoon also descends thereupon, meanwhile, live axle drives under the effect of balanced connecting rod counterrotating moment and rotates the valve block counterrotating, make the water inlet on the water inlet of rotating on the valve block and the fixing valve block pass through state and rotate to the closed state of mutual dislocation gradually by overlapping, pass through area by the coincidence that changes the water inlet, make water-in and water-out reach balance.
After water inlet stops, when water level is lower than hollow pontoon height and position of living in, hollow pontoon and counterweight floating drum just can be got back to initial equilibrium conditions automatically, and the fixedly valve block in the water yield controlling mechanism returns to the closed state that mutual dislocation cooperates again with water inlet on rotating valve block, and carbonated drink is cut off fully.
The beneficial effects of the utility model:
Because the utility model adopts both sides balanced type water inlet mode, fixedly valve block and stressed equate and balanced of rotating the valve block both sides that this just makes in the water yield controlling mechanism overcome uneven frictional force or the single load bearing problem that may cause owing to head pressure.Moreover, because the rotation of rotating valve block is to drive by the moment of torsion that both sides buoyancy-driven mechanical device produces, and the generation of moment of torsion changes to realize by water buoyancy, that is to say, have only the inflow of working as to reach floating drum present position height, and can overcome himself weight and make floating drum do the come-up motion time, just can make the unbalance and generation driving rotation valve block rotating power of the balanced connecting rod that is connected between hollow pontoon and the counterweight floating drum, this has also just guaranteed after water inlet stops, when water level is lower than hollow pontoon height and position of living in, drain valve is thoroughly closed, and has fundamentally stopped the generation of steam leakage accident.
In addition, because the fixedly valve block in the utility model adopts the water outlet of dislocation type variable-area with rotating valve block, so the water displacement of drain valve can be adjusted automatically according to the size of inflow, make turnover water yield autobalance, operating range is wide, and its scope can reach 10%～100% of design maximum amount.
