Description

It is known that injectors of this pair, the use of a donolyntel channel for supplying direct steam into the chamber of this pair, with control of the inlet body, carried out a termination of the supply of one or another pair and the desired pair.

In the proposed injector for supplying the ocTpord of steam to the working chamber, an additional cone of hot steam is used, and for controlling the inlet, the steam inlet valve and gold fik are used to control the steam channel.

FIG. 1 shows a longitudinal section of the injector .m of that pair, and on the fpg. 2-longitudinal section of the automatic injector flow valve. The starting valve 2, the hot steam valve 3, the hot steam cone 4, the hot steam additional cone 5, the water cone 6, 7 and 5 m In addition, a pair, a cone, and a pressure cone 9 and a pressure cone 10. A cone 4 sharp steam and an additional cone 5 sharp steam are screwed into the upper part of the body / injector.

The water cone 6, the cones 7 and 5 m of the vapor and the condensation cone 9 are mounted in a common bush, //. The starting valve 2 is connected to the finishing handle 12.

In the left (according to the drawing) part of the body / injector of that pair are located: valve 13 of the inlet of that pair, screw jaw J4 and spool J5 for closing the channel of the live steam supply. The slide valve / 5 is moved by the lever 16.

In the right side of the housing. The injector has a water divider on the plug 17, on which a handle 18 is fitted.

In the lower part of the injector housing 7 there is a vesta chamber 19, to which an automatic valve of the vest consists of the trophy housing 20, the plunger 2J, the lever 22, the springs .2-3, (Vestova 24, the tube 25 and the cap 26.

On box 27, where you connect the additional channel B and channel B for supplying acute bunker, an adjuvant regulator 28 is located. The nutritional box is equipped with feeding and shut-off valves, is separate from the injector and is not shown in the drawing. The presence of a separate feed box allows you to take the injector from the boiler, not cooling the engine.

When the injector is inoperative, the start-up valve, ac 2 separates the .4 steam from the cone — the steam and the additional channel B of the steam. Valve 13 of the inlet of that pair separates the pipe of that pair and chamber G from the working chamber D of the injector.

The water divider into a plug / 7 in the left-turned position separates the water intake tube and chamber E from the water chamber of the interceptor.

Messenger valve 24 sits loosely in the messenger housing 20. Plunger 21 by means of a spring 23 and lever 22 is placed in the lower position. :.

Before starting the action of the injector, the handle 18 should be turned to the extreme position. Then the water intake pipe and chamber E will be connected to the water chamber W of the injector of that pair. A minor lift of the finishing handle 12 raises the starting valve 2, and the steam from the hot steam chamber A goes through the side openings in the valve 3 and the hot steam goes to the cones and injectors into the messenger chamber 19, lifts the middle valve 24 and comes out. The vapor, which flows at a higher speed along the cones, creates a vacuum in the water chamber F, sucks water from chamber E through the water chamber. W and cones 6, 7, 8 v 9 v drives her through the messenger chamber 19 outward; with this messenger valve, 24 rises. As soon as the suction of water occurs, the end handle 12 should be lifted to the full. Then the starting valve 2, with its shoulder, lifts the hot steam valve 3, and the steam from chamber A through the side openings in the hot steam cone 4 enters the additional hot steam channel B and further to the hot steam channel B and the additional hot steam cone 5. The steam and water entering the injector are mixed and the cones 7, 8 E 9 pass. The water velocity increases due to the steam velocity.

When water passes through the pressure housing JO, its velocity decreases, but the pressure increases and becomes larger than in the boiler. Pass the discharge chamber and the water enters the feed box, raises the feed valve and enters the boiler.

As soon as the normal operation of the injector is established, part of the water from the injection chamber // flows through the tube 25 under the plunger 21 and lifts it. In doing so, the lever 22 rotates, presses on the cap 26, compresses the spring 23 and closes the messenger valve 24 for the entire duration of the injector operation.

At the end of the work of the injector, the pressure in the pressure chamber And drops; spring 23 lowers plunger 21 and messenger valve 24 sits

free.

Switching the injector to work with steam is performed by turning the lever 16 to the left, approximately 180 °. When this happens, the screw rod 14 rises up and the spool 15 closes the channel B of the live steam.

Simultaneously with the raising of the screw rod 14, the associated steam valve 13 also rises. The last of the chamber: D m that pair enters the working chamber D and the cones 7 and S m that pair.

The start of the injection of the steam injector is performed only by direct steam with the valve / 5 inlet of the steam steam closed.

Switching the injector to the operation with crushed steam should be carried out only when the locomotive regulator is open and the steam is brought to the injector.

Subject invention

An injector of that steam using, for supplying steam into the chamber of that steam, an additional channel blocked by the valve of that steam, controlled by a single lever by letting in steam, and stopping the steam supply, characterized in that to feed the steam into the working chamber an additional steam cone has been applied, and an inlet of the steam inlet and a spool for closing the channel of the steam are applied to control the inlet-impregnated steam and the valve.
