Description

(The invention relates to the type of devices for vdotnyh boilers for signaling the position of the water level in them, using a vessel with a float connected by branch pipes from the steam and water areas of the boiler. If the water level in the boiler falls below the limit, the furnace may expose the boiler, causing metal to burn out, causing cracks, bulges, leakage of pipes, anchor bolts, etc. Increasing the water level above the limit causes water to be thrown through the cylinders, and hence excessive fuel consumption, damage to the cylinders and engine This is important in locomotive boilers, where the height of the level in the boiler, during the movement of the engine, depends on a whole number of reasons, ng / example, prfil path, train weight, speed of movement, weather conditions and many / other .

In the proposed device, the vessel is equipped with two g. Separate, installed at the lowest and the highest limit levels, x-floats associated with the piston. supplied with spring spools and moving in the transverse septum of the vessel. Moving a single out of the floats, in case of violation of one or another limit level, causes movement

236);

the spool opening the channel for the steam outlet either to the signal whistle or to a special cylinder, the piston of which acts on the valve supplying steam to the injector,

In FIG. 1 is a side view of a device with a steam boiler for indicating the position of the water level therein; FIG. 2 is a vertical section of it; FIG. 3-horizontal section of the partition; FIG. 4-vertical section of it; FIG. 5 is a diagram of the connection of the device with the injector.

The cylindrical body / fixture is attached to the boiler by the flanges of taps 2 and 3 at the same level as the water glass taps. - B. Case 1 two floats 4 and 5 are inserted, of which the float 4 is supported by screws 6 at the level of the lowest permissible water limit in the boiler , and the float 5 is on the screws 7 at the level of the highest permissible limit of water in the boiler. The float 4 is connected by a rod 8, passing in the middle of the through channel of the float 5 with a piston I, in which a spool 10 is inserted, pressed by the coil spring 77 (Fig. 2). In the upper part of the housing 7 there is a pendulum partition 12 with three cylindrical holes drilled in it, from; which two are connected 75 and 16. The bore of the middle hole is a piston P with a spool 10 closing channel 15. The float 4 below has a guide rod / 5 which enters the tide 14. The upper float 5 is connected to two pistons 18 and 19, which enter the side openings of the partition. The piston 18 is provided with a spool 20, which is loaded with a coil spring 25 and closes channel 16. The piston / serves to direct and balance the float 5. A lubricant whistle 27 is attached to the output channel 75 of the housing 7, and to lubricate the pistons there is an oil can 22, and to blow the device down The tap 25 is screwed on the top. The housing 7 is closed by a cover 2 /. For free circulation of water and steam, there is an opening 26 in the device in the septum 72 (Fig. 3). When the water level in the steam boiler begins to fall below the permissible limit, the float will also begin to fall, and the piston 9 associated with it with the spool 10 will lower and open the channel 75 to allow steam to pass into the whistle 27, which will begin to act and will pay attention to the staff. When v the water level rises again, the float also rises, causing the valve 10 to close the channel 75, and the steam output to the whistle 27 will stop. When the water level begins to rise above the limit, and the float 5 also begins to rise, the piston 18 will rise along with neither the spool 20, which opens the channel 75, from where the channel 75 will go to the signal whistle 27.

Instead of a whistle, a special cylinder 27 (Fig. 3) with a piston 28 is connected, the KOTopofo rod 29 is connected to the handle 30 of the steam valve 57 from the injector 52. In this case, the channels 75 And 7 do not interconnect with each other, but do themselves as shown in fig. 3 dotted line. Through the channel / 5, steam is supplied to the cylinder in the projectile under the pile 28, which is

the upward movement lifts the handle 30 from the injector, which causes water to be pumped into the boiler. Channel 16 -76 is connected to the upper part of cylinder 27, and steam enters the cylinder in space above 28, lowers knob 50 with valve 57 downwards, which stops the action of injector 52. In this case, separate cylinders 27 are needed for each injector. 27 steam for pumping water through the channel 75 is supplied to the lower part of the cylinder 27, and to signal the need to stop the action of the injector, the steam through the channel 16 is supplied to the signal whistle 27 of the tool. At the same time, the attendants, having heard the whistle signal, terminate the action of the injector. The device can be applied to stationary boilers as well as to locomotive and steamboat ..

The subject matter of the invention.
