Description

In the proposed device for feeding steam boilers, the spool with a piston receiving a back-and-forth movement is provided with a through cavity in the piston communicating through the cavities in the rods with the water tank, and is intended to receive from it a certain portion of feed water supplied at the corresponding positions x spool into the boiler

through the pipes connecting at this moment the cavity with the steam

and water spaces of the boiler.

In FIG. 1 is a vertical sectional view of a device for feeding steam boilers; FIG. 2-vertical longitudinal section of the spool; FIG. 3-top view of it; Fig. 4 is an end view thereof; FIG. 5 is a vertical section of a modification of the device; FIG. 6 - vertical section of the spool to it; FIG. 7-top view of the spool; FIG. 8 - view from the end; FIG. 9 is a vertical section of the form of the device; FIG. 10-side view of the spool to it; FIG. 11-view spool from the end.

The housing L of the device through pipes 7 communicates with pipe 8, leads to the vapor space of the boiler, and pipe 9 with the water space of the boiler. Gold in the case (236)

A nickname with a piston 2 equipped with a cavity a communicates {it with a cavity b and b in its rods. Through the pipe 10, steam is supplied to the injector 15, which feeds water from the main water supply system to the hermetically sealed tank 11, from which the water flows through pipe III to the spool L. When the spool is positioned in FIG. 1, the steam in the cavity and through the cavity and channels and into the rod enters the pipe K) to the injector, 15, which sucks the hearth from the pipe 12 to the tank 11, from where it comes from. The pipe 13 enters cavity b of spool A, which is closed by a spring-loaded valve to the Z.-Zolotnik L, reciprocating is reported by means of a plug 14 connected to the crank device. When the piston moves () and to the left, under the pressure of water in the cavity (J coming there from pipe 13, valve k will open and water will flow into the cavity l of the piston of the spool. Steam entering pipe 7 in CAVITY 4, both CTOPOHI, The first piston balances the piston 2 of the spool and the control valve G, which is pulled by a spring placed in the pipe 5. At the extreme left position of the valve A, the cavity filled with water A is located under the valve G and above the pipe 9. Steam from pipe 8 will open the valve 6 and water from the cavity and pours through the pipe 9 into the boiler, after which the valve G p The action of the spring closes. When the spool is subsequently moved to the right, the steam from the polo part enters the pipe 10 and t, e. In the modification of the device shown in Figs 5-8, the valve L is equipped with figured windows c, a which alternately in the extreme positions of the spool, they communicate with the boiler through the steam line 9 and the chamber located on the boiler feed line. There is a cavity in the spool, which communicates through the holes provided with valves to, with cavities g. rings on the ends, in those in the cavity of the spool. The bushings are provided with openings through which the cavities g are continuously connected via pipes 7 to the tank 10. When the spool is positioned as shown in FIG. 5, the cavity a of the spool is in communication with chamber b, into which water has flowed from cavity a and, due to the sparseness from this in cavity a, valve 6 is closed. Upon further movement of the spool in any direction in the cavity a, one of the valves k will open, and water from the cavity r will flow into the cavity a, and the cavity r on the opposite side of the spool will suck and fill with water coming through one of the pipes 7 from the tank 10. At the extreme position of the spool, the figured windows in the steam line 9 with chamber b will communicate, at which position the steam pressure on both sides of the valve ti will be balanced, and under the action of the spring valve 6 will fall and the water from chamber b will flow into the boiler. When the spool moves backward, water from the cavity flows back into the tf chamber, etc. The pipe S comes in D case 1 pair, balancing the spool, so that a minimum force is required to move the latter. Water enters from the hermetically sealed tank 10 by gravity, whereby a vacuum is formed in it to suck water from pipe 11. In the embodiment of the device shown in FIG. 9-I steam from the boiler

since g

II Y g} is supplied through pipes 8 into space c formed by bushings 3 on both sides of the valve spool A, from where steam enters chamber 4 located on the feed line of the boiler when the piston passes the channel and said chamber. When the spool moves, for example, to the right, to the extreme position, water from the right cavity flows into the cavity of the spool, and in the left cavity there is suction of water coming from the tank through pipe 7. When the spool is at the extreme position, steam from the space c flows into chamber 4, which is previously filled with water from cavity o; the valve 5, which until this moment is under pressure of steam from the boiler, is balanced by the pressure of steam from the space C and, compressing the spring, opens, while releasing water from chamber 4 into the boiler through pipe C. When the valve moves back, when the water-filled cavity approaches and to the channel of the chamber 4, the steam access to the last of the space c is stopped, and the valve 5 is closed by the action of a spring, after which the water from the cavity flows into the chamber 4, etc. of boilers, characterized by the use of spool A with a piston 2, equipped with a cavity for receiving certain portions of feedwater, which cavity is communicated through cavities bn b in the rods with the water tank 11 and in the corresponding positions of the spool, during its return-and-forward motion, with the boiler to enter it contained in the cavity (I portions of water through pipes 5 and 9. Section 1, characterized in that cavity a communicates with the water tank P by means of pipes 13 and 10, the first of which is intended for supplying water into the cavity a through the cavity closed by valve b in the valve stem and the second - for steam supply from cavity a through polo Item 9 and channels a, and in a brush to the injector 14 .. pipes 7/7 for communicating cavities according to the subject of the invention, 1. Device for power supply - steam 2. Forms of the device according to 3. In the device according to claim 1 use
