Description

Patent No. 7319 describes a centrifugal water trap, consisting of a horseshoe-shaped chamber installed above a blind wall, placed inside the boiler, with a steam inlet at the bottom and an exit at the top, the outer wall of which is made bevelled (conical) to enable it to be separated by centrifugal forces of water to flow through a slot in the lower part of the chamber into an annular chamber equipped with water discharge tubes.

In the present invention, an automatic drainage system is applied to the water separator described, consisting of a closed tank, communicating with a water separator slot and fitted with a float with a rack mounted on the bristles mounted on the tail of the plug of the condensate drain plug.

In FIG. 1 shows a vertical section through a centrifugal water separator; FIG. 2 is a horizontal section along the line AB in FIG. one; FIG. 3 is the same, along the line CD in FIG. one.

The centrifugal water separator placed at the top of the reservoir of the diverter 1 consists of a spiral chamber 2 (Fig. 2) with an inlet 3 for parr and an outlet 4, the outer wall 5 of which is made oblique (conical); under the b, the chamber has a tapered shape around the circumference, but does not reach the wall 5, so that a slit 7 is formed along the entire chamber 2 near the outer wall, connecting the chamber 2 with the chamber 8 of the drainage tank 1; the latter is equipped with a conventional hollow closed float 9, connected from above to rod 10, the other end of which is passed through the center of the water separator and has a pressing rod outside the bottom 11 with a nut from the outside; The rod 12 is attached to the bottom of the float at one end, the other end of which is placed in the stuffing box; the rod 12 is equipped with a toothed rack 12a coupled to the gear gear 13, mounted on the tail of the conical plug 14, fitted with a spring 18 and placed in a drain pipe 15 having an inlet for water to the hole 5a and an outlet 156. The pipe 15 is connected to a stand 16 attached bolted to the tide 17. The steam from the boiler through the pipe through the inlet 3 passes through the spiral chamber 2 and due to the rapid passage of steam through the latter and due to the developing centrifugal force, water particles and some impurities, as more

heavy in comparison with dry steam, pressed against the wall 5 of chamber 2, but since the latter has a slope that ends in chamber 8, water and impurities are drawn through the slit 7 into the drainage chamber 8 and when the water level rises, the float 9 automatically rises together with the toothed rack 12a and, rotating the gear 13, turns the tap 14 and opens the window 14a to drain the water through the pipe 15 After the condensate is drained from the chamber 8 in this way, the float 9 is lowered and the rack 12a turns the gear 13 in the opposite direction and closes the valve 14. Released outside Part of the rod 10, the end of which there is a helical spring 11, enables fast

and at the time, determine the operability of the automatic drainage system.

The subject matter of the invention.

The use of a centrifugal water trap 1 in Fig. 1, described in patent No. 7319, with a hollow closed float 9 equipped with a rack 12 o coupled with gear gear 13 mounted on the tail of the plug valve 14, closing the condensate outlet to the drain pipe 15, which the drainage valve communicates with the water trap slot 7, located on the inner side of the wall 5 of the spiral chamber 2 water separator.
