Description

The proposed device for automatic regulation of the supply of water and fuel to the steam heating boiler is intended to prevent accidents and reduce exploitation costs by using a metal float closing the valve and electromagnets acting on the valve closing and opening the water access to the boiler, and regulating the supply of fuel into the furnace of the boiler it is produced in such a way that with an increase in pressure in the boiler, steam through the piston and the system of levers covers the lies, podak P1, and its fuel firebox, or depending on the outdoor temperature, regulation takes place by means of a float moving in a thermometer tube placed outside the house through the relay and 1 of the electromagnet whose moving cores act on the ratchet wheels which are aa second crane, supplied with oil .

The drawing shows schematically the boiler with the proposed device.

In the glass tube 8. communicatively, with the boiler 1 on the similarity of the water tube, a hollow metal ball 9 is floating, which closes the conduits of the wires 10 and 14, which are inserted into the lower one and the upper channels of the tube 8 and are connected to the main current source 11 12. Relay 13 and 15 are included in chains 10 and 14 for exciting

electromagnets 5 and 16. Electromagnet 5 has a bark 6, and for an electromagnet 16, a shoulder 17 of a double-arm lever rotating around an axis 18 serves as a core. The armature is kept open by springs 7 and 19 when the depy is unlocked. water is in the boiler, and the second lever arm 17 has a hook-up hook 20, which holds the hook in the upper part of the sleeve 4 and holds the bottom pin 3, while the boiler is filled with water. The tank 21 is connected to the height of the tank by a pipe 22, with a supply network and a pipe 2 with a boiler. The pipe 22 is closed by a valve 23, through the arm 24 of the two shoulders, rotating on the axis 25, the second arm of which is provided with a hollow ball 26 floating on the surface of the water. Water 22 enters through pipe 22, which is obtained when steam is cooled, which heats the room where it enters the boiler through pipe 29. Steam 28 enters steam from a steam boiler to facilitate the movement of water from tank 21 to boiler 1.

In the pilot 31, communicated by means of the tube 32 with the boiler steam drum 1, the piston 30 moves, the stem 33 of which, held by the springs 34, is connected pivotally to the rocker arm 35, acting through the pull 36 on the crane 37, which regulates the flow of fuel from the tank 41 through pipe 38 to the furnace 39 of the boiler 1, with an increase in pressure in the latter, at whose valve 37 can not be closed completely, as there is an emphasis limiting the course of the handle of the crane. The spring 4sO keeps the valve 37 in the open state at normal steam pressure in the boiler.,

To regulate the supply of fuel, depending on the temperature of the outside air, a thermometer 43 is placed outside the house, in which a float .56 moves with a rod 57, at the free end of which there is a metal cross member 58, to which is pivotally attached

two glued plates that form the hinged spring contacts 60, with at one end of the cross member 58 the bottom plate is metal, and the top is from non-conductor, and at the other end is on the back side. Each pair of plates is held in a horizontal position by two springs 61 and 62 attached to a crossmember 58 connected by wire 69 to one of the wires of the highway 68 transmitting current from source 70. To the left and to the right of stem 57 at locations corresponding to degree thermometer m, The pin nlashinkn 63 is located, the virgin side plates are united by a metal plate 64, and the right side is the metal plate 65, which plate through, relays 66 and 67 are connected to another wire of highway 68. Relay 66 n 67 excite parallelly inserted electromagnets 46 and 47, the moving cores of which are equipped with rods 48 and 49, having 50 1 and 51 pawns open at the ends, turning ratchet wheels 44 and 45 with teeth directed from one wheel clockwise, and the other against , stuck on the same axis with the valve 42, feeding fuel from the tank 41 through the pipe 38 to the boiler 39, 1. Between the screws 52, 62 and 54.54 are the protrusions 53 and 55 of the rods 48 and 49, limiting the course of the moving cores of the electromagnets 46 and 47 in such a way that bobachki 50 and 51 turn t ratchet wheels 44 and 45 to a limited number of teeth .;

When there is no water in the cauldron, the ball 9 will close the circuit to the Reija 13, and the electromagnet 5 will be excited, which means that there is no measles 6, which is fastened to the sleeve 4, which rises

upward, the flaps 3, the water pipe 2, and the hook 20, hitting the hook of the sleeve 4, will keep the valve lifted up all the time when the boiler is filled with water through pipe 2 from the bai 21. According to the tank 21 with water 3/3 heights, a ball 26 floats turns the double-arm lever around the axis 25 and the shoulder 24 retracts the valve 23, which closes the water access to the tank 21. Upon filling the boiler 1 with water, the ball 9 floats up and closes the relay 15 circuit, causing an excitation; an electromagnet 16 that attracts the shoulder 17 two shoulders levers, and the hook 20 jumps off the hook LCI 4, whereby the shutter 3, down, closes the access of water to the boiler 1. By increasing the pressure in the boiler 1 steam pressure on the piston 30 with the rod 33, the latter povrachivaet rocker 35 which presses against the thrust 36, and the latter rotates and covers the valve

37 pipelines 38 supplying fuel to the furnace 39. Oil flow depending on the outside air temperature is controlled by means of a float 56 moving under the action of a mercury column in the thermometric tube 43. The stem 57 of the float 56 is raised or lowered depending on the outside air temperature , connects the spring contacts 60 to the contact plate

64 or 65, why relays 66 or 67 are closed and electromagnets 46 or 47 are excited, the movable cores of which 48 or 49, rising, under the influence of impulse currents, turn the ratchet wheels 44 or 45 with their pawns 50 or 51, turn valve 42, thereby reducing or increasing the flow of oil from the pipeline

38in 39, with it, / if the ratchet wheel 44 opens the valve 42 when the temperature drops due to the closing of the chain con-. steps 60 and 64, the xpaiHOBoe wheel 45. at this time, is stationary, and as the temperature rises, the circuit closes 60
