Abstract

The invention relates to devices for removing condensate from heat consuming apparatuses while simultaneously controlling the level of condensate in collector (C) 1. The invention improves reliability by stabilizing the flow characteristics. Condensate flow from C 1 enters the drain pipe (T) 4. From T 4 through the throttle opening 8, condensate enters the cup 6 and through choke 9 further into T 4. In case of filling C 1 above the connecting level of the impulse tube 10, part of the condensate flow through the adjustable throttle 12 into the control cavity (P) 11. In the throttle 12, the condensate boils and depending on its initial heat content in P 11 a certain pressure is established, which at a certain position of the cup 6 becomes equal to the pressure in it. A gap is established between the cup 6 and the saddle 7, through which the corresponding flow of condensate passes, thus maintaining its constant level in C 1. When the level of condensate in C 1 is lowered, condensate (steam) with a higher heat content enters the tube 10. The pressure in П 11 increases, the cup 6 moves downwards, the flow area of the throttle 9 decreases, the pressure in the canal station b increases and with a certain decrease (Condensate consumption cup 6 is set in an intermediate position. 1 ill.

Description

The invention relates to a device for draining condensate from heat-consuming devices while controlling the level of condensate in the collectors.

The purpose of the invention is to increase reliability.

The drawing shows a device for condensate drainage, General view.

The condensate drainage device comprises a condensate collector 1 with heating surfaces 2 arranged therein. A drain pipe 4 is connected to the condensate volume 3 with an outlet valve 5 installed therein, having a shut-off member made in the form of a movable inverted nozzle 6 and a seat 7. In the saddle 7 a central throttle hole 8 is made, the edges of the nozzle 6 interact with the seat 7 to form an alternating throttle 9. The impulse tube 10 reports the vapor volume of the collector 1 (at the phase separation) with the control cavity 11 of the nozzle 6 n hell with its bottom, while an adjustable throttle 12 is installed on the tube 10 'up to the cavity 11. A throttle 13 is installed on the part of the tube 10 connecting the collector 1 to the drain pipe 4 behind the valve 5.

The condensate stream flows from the collector 1 to the drain pipe 4 and through it through the throttle hole 8 under the glass 6 and through the throttle 12 then to the drain pipe 4 and the drain line. At this time, part of the condensate stream (when filling it in the collector 1 above the junction of the impulse tube 10) passes through an adjustable choke 12 into the control cavity

11. In this case, the condensate boils in the throttle 12 and, depending on its initial heat content, a certain pressure is established in the cavity 11, which at a certain position of the nozzle 6 becomes equal to the pressure in the nozzle 6. A certain clearance is established between the nozzle 6 and the seat 7 (throttle value 12 ) through which the corresponding condensate flow passes, maintaining a constant level ⁵ in collector 1. When the condensate level in collector 1 decreases, condensate (steam) with a higher heat content enters the pulse tube 10 by virtue of which, the pressure in the control strip 10 11 of the nozzle 6 increases, the latter moves down, the passage section of the throttle 9 decreases, the pressure in the nozzle 6 increases and with a certain reduced flow rate of condensate, the nozzle 6 is set in an intermediate position.

The invention relates to devices for draining condensate from heat consuming apparatuses with simultaneous regulation of the level of condensate in collectors. The purpose of the invention is to increase reliability. The drawing shows a device for draining condensate, a general view. A device for draining condensate contains a collector 1 of condensate with heating surfaces placed in it. 2. The condensate volume 3 is connected to a drain pipe 4 with an exhaust valve 5 installed in it, having a shut-off member in the form of a movable inverted cup 6, and a saddle 7. In the saddle 7 there is a central throttle opening 8, the edges of the cup 6 interact with the saddle 7 with the formation of a variable throttle 9.

The flow of condensate flows from collector 1 to the discharge conduit 4 and through it via the orifice 8 and 6 under the glass through the throttle 12 further into the discharge conduit 4 and the drain line. At this time, part of the condensate flow (when it is filled in the collector 1 above the connecting point of the impulse tube 10) passes through the adjustable choke 12 into the control cavity 11. At the same time, the condensate boils in the choke 12 and depending on its initial heat content pressure, which at a certain position of the glass 6 becomes equal to the pressure in the glass 6. A certain gap is established between the glass 6 and the saddle 7 (the value of throttles 12). Through which the corresponding flow rate of condensate passes, maintaining a constant level in the collector 1.
