Background technique
The STEAM TRAP of conventional art adopts the float-ball type structure more, in order to make ball float can in water, be in float state all the time, ball float adopts thin walled structures usually, be generally about 1mm, because the ball float many places are impacted under the operating conditions in the frequent steam of pressure surge, under the effect of steam impact force, very easily deform or damage, consequently directly cause discharging the water hole shutoff and lost efficacy, cause air leakage amount to increase or draining malfunctioning.
In addition, adopt the mode of structure draining (being the definite value discharging) of decide draining of bore discharge orifice because prior art, under system loading changes big situation, when the water yield hour, ball float will frequently float or fall, and very easily causes the ball float damage; When the water yield is big, can't get rid of because of unnecessary water, directly have influence on the heat exchange of up-stream system.That is to say: because the drainage works of prior art STEAM TRAP belongs to the discontinuity draining, can't realize the continuity discharging, this just directly has influence on downstream flash distillation effect.
Summary of the invention
Purpose of the present invention is just at existing deficiency in the above-mentioned prior art, and a kind of structure is more reasonable, the discharging water yield is adjustable and the balanced shearing type air water separation steam trap of energy continous-stable discharging and provide.
Purpose of the present invention can realize by following technique measures:
Balanced shearing type air water separation steam trap of the present invention comprises and is provided with the tank body that vapour, water are mixed into inlet, and be arranged on drain valve in the tank body, described drain valve comprise two ends be enclosed construction tubular valve body, be arranged on the upper shed formula effluent pipe mouth of tubular valve body intermediate portion and be positioned at the under shed formula water inlet pipe mouth that plays balance water inlet effect of effluent pipe mouth both sides; Be provided with the water yield controlling mechanism that constitutes by the dynamic and static valve plate that cooperatively interacts in the valve pocket between drain valve water inlet pipe mouth and effluent pipe mouth, the center portion of described dynamic and static valve plate respectively is processed with an axis hole with concentric manner, be processed with the water inlet that quantity equates, the aperture is identical, the position, hole is corresponding mutually around separately axis hole, and between the peritreme of per two adjacent water inlets distance more than or equal to the aperture of water inlet; Being used for driving device that the moving valve plate of water yield controlling mechanism rotarily opens is made up of the live axle that combines with moving valve plate, the buoyancy-driven mechanism that is made of balanced connecting rod, hollow pontoon and balance mass that combines with the live axle overhanging end; The volume of described hollow pontoon is greater than the volume of counterweight thing, but it is identical in quality.
Be provided with the erosion control web plate in vapour, the water of tank body is mixed into inner chamber between inlet and the drain valve, the inner chamber that is to say tank body is divided into the drain valve installation cavity by the erosion control web plate and vapour, water are mixed into the chamber.
More specifically say, respectively be provided with a water yield controlling mechanism in the tubular valve body inner chamber of the present invention between left side water inlet pipe mouth and effluent pipe mouth, between right side water inlet pipe mouth and the effluent pipe mouth; Described moving valve plate is installed in the tubular valve body inner chamber by the live axle that crosses tubular valve body, respectively be provided with a horizontal balanced connecting rod at the two ends of described live axle, and two balanced connecting rods 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 valve body both sides, the counterweight thing all is installed in balanced connecting rod by link two ends.
In addition, described hollow pontoon should adopt 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:
After vapour, water mixture enter tank body from water intake, by having filtering solid particles and preventing that the erosion control web plate of percussion from entering in the tank body chamber that drain valve is installed, increase along with inflow, water in the tank body just can enter by the left and right water inlet pipe mouth that is arranged on drain valve tubular valve body bottom in the valve pocket between water yield controlling mechanism and the water inlet pipe mouth (at this moment, the water inlet on the dynamic and static valve plate in the drain valve water yield controlling mechanism is in closed state with the fit system of mutual dislocation).When water level is elevated to hollow pontoon height and position of living in, because hollow pontoon is bigger than mass volume, the suffered buoyancy of hollow pontoon is also just greater than mass, the imbalance of buoyancy makes hollow pontoon and the mass disequilibrium that is in state of equilibrium when anhydrous state, and then make the balanced connecting rod that is connected between hollow pontoon and the mass unbalance and produce rotating power, meanwhile, live axle drives moving valve plate rotation under the effect of balanced connecting rod rotating force, the water inlet on water inlet and the quiet valve plate on the valve plate is rotated to overlapping conducting direction gradually by the closed state of mutual dislocation.Along with the increase of inflow, the rising of tank body middle water level, moving valve plate also can continue rotation under the drive of live axle, overlap fully with water inlet on the quiet valve plate until moving valve plate.At this moment, the water-outlet quantity of balanced shearing type steam-water separator also will reach peak work capacity.
When the inflow of tank body reduces, drawdown in the tank body, hollow pontoon also descends thereupon, meanwhile, live axle drives moving valve plate counterrotating under the effect of balanced connecting rod counterrotating moment, make water inlet on water inlet and the quiet valve plate on the valve plate by overlapping on state,, make water-in and water-out reach balance by changing the coincidence conducting area of water inlet gradually to the closed state rotation of mutual dislocation.
After the tank body water inlet stops, when water level in the tank body is lower than hollow pontoon height and position of living in, hollow pontoon and mass just can be got back to initial equilibrium conditions automatically, water inlet on the dynamic and static valve plate in the drain valve water yield controlling mechanism returns to the closed state that mutual dislocation cooperates again, and carbonated drink is cut off fully.
Because drain valve adopts both sides balanced type water inlet mode among the present invention, this just makes dynamic and static valve plate both sides in the water yield controlling mechanism stressed equate and is balanced, overcomes because uneven frictional force or the single load bearing problem that head pressure may cause.Moreover because of the rotation of moving valve plate is to drive by the moment of torsion that both sides buoyancy-driven mechanical device is produced, and the generation of moment of torsion changes by water buoyancy and realizes.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 moving valve plate rotating power of generation driving of the balanced connecting rod that is connected between hollow pontoon and the mass, this has also just guaranteed after the tank body water inlet stops, thoroughly the closing of drain valve when water level in the tank body is lower than hollow pontoon height and position of living in fundamentally stopped the generation of steam leakage accident.
In addition, because the dynamic and static valve plate of drain valve adopts the water outlet of dislocation type variable-area among the present invention,, make turnover water yield autobalance so the water displacement of drain valve can be adjusted automatically according to the size of inflow, operating range is wide, can reach 10%~100% of design maximum amount.
