Description

(S) FUEL FLOW REGULATOR.

one

The invention relates to hydraulics.

A device for controlling the flow rate of a liquid is known, which includes a housing with inlet and outlet fittings, a float mechanism and a dispenser 1.

The amount of fuel consumption is set by the metering unit depending on the level of liquid in the fuel chamber and does not depend on the operation modes of the consumers of fuel consumption.

The closest to the technical essence of the invention is a device for regulating a continuous flow of fluid, comprising a housing with inlet and outlet fittings in which the inlet and outlet valves are located, the float valve; Anism associated with the dispenser, a safety device associated with the inlet valve 2.

In this case, the regulation of the flow rate of the liquid is carried out by float

mechanism together with the dispenser, as well as two safety devices according to the level and temperature of the liquid. The fuel consumption through the regulator remains enabled, even with the development of abnormal combustion conditions in heating furnaces in the event of a leakage of the fuel lines, accumulation and ignition of fuel in the furnace. As a result

To the fuel enters the furnace operating in a fire situation, until the fuel in the controller warms up from the flame to the temperature at which the fuse of the 5th device operates according to the temperature of the liquid.

The aim of the invention is to increase the reliability of the controller by preventing a fire situation.

This goal is achieved in that a safety device is installed in the controller, which contains a spring-loaded hammer with a latch, under which a hinged lever connected to the exhaust valve spool, a spring-loaded two-arm lever connected by a smaller shoulder through the hinge to the spring-loaded drummer, and a large shoulder with a preservative element, made in the form of a thread and a cap made of elastic polymer, mounted on a rod installed in the furnace pan. FIG. 1 shows the regulator, a longitudinal section; in fig. 2 - the same, a cross-section with a section of the exhaust valve. The regulator consists of a housing 1 with inlet and outlet fittings, a lid 2 containing an adjustment knob 3 interconnected with a spring-loaded exhaust valve C, a float mechanism 5 fixed on the lever 6 with prismatic projections on which the dispenser 7 is mounted. The lever 6 is fixed to the axis 8 of the bracket 9 and serves to communicate the float mechanism 5 with the saddle 10 of the dispenser 7- On the bracket 9 the safety device of the fluid level in the regulator consisting of a lever 11 and a spring-loaded latch 12 interacting with the lever is hinged 13 on the lid 2 with screws H in the housing 15 secured the device without danger, containing a spring-loaded drummer 16, held in the cocked position by a latch 17 and a spring-loaded two-arm lever 18 connected by a smaller arm through a hinge with the latch 17 of the spring-loaded drummer 16, and shoulder with a safety element, made in de thread 19 and the cap 20 of elastic polymer with an internal annular ledge mounted on the annular groove made on the rod 21 installed in the pan 22 of the furnace. The device can be used in conjunction with several control systems. The fuel consumption regulator is as follows. A hinge 23 is placed between the latch 17 and the two shoulders lever 18, the roller 2 is fixed at the latch 12, the sump with filter 25 is located at the entrance to the regulator, and the hinge lever 2b is located under the drummer 16 at the inlet of the regulator. The fuel enters the settling tank with the filter 25 through the inlet fitting and enters the internal cavity of the regulator through the channel of the seat 10, raises the float mechanism.5 until the metering unit 7 adjusts the fuel consumption equal to the flow rate established by the exhaust valve k. If the tightness of the fuel line breaks down at the point of its connection with the burner, fuel leaks to the furnace pan 22, the fuel accumulating in pan 22 affects the material of the cap 20 and destroys it. The double-shouldered lever 18 is released from fixation and, under the action of a spring, turns, down and presses the hinged lever 2b. The latter, acting on the exhaust valve k, closes the fuel outlet to the furnace. When a burning fuel enters the furnace tray 22, the thread 19 burns out and the safety device operates in the same way. Thus, the fuel consumption regulator helps prevent a fire situation in the event of a malfunction of the furnace. Claims of Invention A fuel consumption regulator for a furnace, comprising a housing with inlet and outlet fittings, in which the inlet and exhaust valves are located, a safety device and a float mechanism associated with the inlet valve, characterized in that, in order to improve the reliability of the controller by preventing fire situation in case of malfunction of the furnace; a safety device is installed in it, containing a spring-loaded drummer with a latch, under which a ball-lever is installed, a release connected to the spool A spring-loaded two-arm lever connected to the smaller arm through a hinge with a spring loaded latch, and a large arm with a safety element made in the form of a thread and a cap made of an elastic polymer, is fixed by Horq on a rod installed in the furnace pan.
