In gas-entered passageway 21, be provided with the body import dirt removing device 7 of calming the anger.Described steam condensate inlet check valve 15 and water outlet safety check 16 can place the outside or inner of resevoir.

Working procedure of the present utility model is: be to have pressure vapour (gas) to be used as power, to realize that steam condensate flows to the high pressure place from low pressure.Steam condensate is in vapor condenses water inlet dirt removing device 14, steam condensate inlet check valve 15 flow into the resevoir of being made up of resevoir housing 1 and resevoir loam cake 2, and (stream passage 20, exhaust passage 22 and demister drain into atmosphere to the gas in the resevoir through pilot chamber 23, main vapour.Resevoir is interior along with the increase that flows into the water yield, liquid level in the resevoir raises, band arm float 9 is floated, when float arm is in level and ball float lateral deviation when high, under the effect of spring 11, band arm ball float 9 can produce the rapid uplift action, promotes reversing piston 6 by connecting rod 10 and produces a radical and short and small stroke, and consequently: reversing piston 6 at first cuts off (the connection of stream passage 20 and exhaust passage 22 of main vapour; (stream passage 20 is communicated with to make admission (gas) passage 21 and main vapour afterwards; Have pressure vapour (gas) body through admission (gas) passage 21, (stream passage 20 at first enters pilot chamber 23 to main vapour; Promote reversing piston 6 and move up, make in pilot chamber 23 and the resevoir and connect fully, have pressure vapour (gas) body to enter and make its pressure rising (having approached pressure vapour (gas) body pressure) in the resevoir; Owing on resevoir, be provided with steam condensate inlet check valve 15 and water outlet safety check 16, make steam condensate can only realize flowing to the outside network direction, so under the effect that pressure vapour (gas) body pressure is arranged, steam condensate inlet check valve 15 is closed, water outlet safety check 16 is opened, and steam condensate is pressed into the higher outside water of condensation pipe network of pressure; Make the realization draining.Along with water of condensation is discharged, drawdown in the resevoir, when drawdown during (this moment water outlet safety check 16 still be in the water of condensation) to certain altitude, float is loss of buoyance gradually, under the effect of gravity and spring tension, band arm float 9 descends fast, moves downward by connecting rod 10 pulling reversing pistons; At first cutting off has pressure vapour (gas) body (connection of stream passage 20 makes the (connection of stream passage 20 and exhaust passage 22 of main vapour then through admission (gas) passage 21, main vapour; Recover normal pressure in the resevoir.Water outlet safety check 16 externally cuts out under the effect of ductwork pressure, and steam condensate begins again to flow in the resevoir.Again and again steam condensate is discharged to the higher pipe network of pressure from the pressure lower with this.

Because the pressure of water of condensation is higher than barometric pressure, pressure reduces behind the inflow atmosphere, can produce secondary steam (so-called " flash distillation "); For reducing flash distillation, behind exhaust passage 22, be provided with the demister of forming by damping net 17, heat conducting fiber 18, gland 19, make and remain certain pressure in the resevoir, the gas in the resevoir 1 is discharged the generating capacity of minimizing " flash distillation " vapour having under the situation of pressure; Part steam condenses into water of condensation and flow back in the resevoir in demister.

After guide-type condensed-water recovering device was directly installed on the STEAM TRAP of steam heat-exchanging equipment, drain opening was connected to pipe network.Guide-type condensed-water recovering device is through the supercooled state working condition tests, and through the cold conditions working condition tests, its performance has reached designing requirement.
