Abstract

PURPOSE:To effectively prevent ol leakage from an injection port of nozzle at fire extinguishing operation by closing a solenoid value in an appropriate lapse of time after the stoppage of an electromagnetic pump when fire of burner is extinguished. CONSTITUTION:For extinguishing fire of a burner 8, when an electromagnetic pump 6 is stopped, with a solenoid valve 4 being opened, delivery oil pressure of the pump 6 is released to an oil tank to be rapidly damped, because a passage is established from the electromagnetic pump 6 through a nozzle 1, an electromagnetic proportional control valve 3, the solenoid valve 4 to an oil feed line 5. In this manner, when the solenoid valve 4 is closed after the outlet pressure of the pump 6 has been sufficiently damped, and also after a lapse of time when leakage of oil from an injection port 9 of a nozzle 1 can be avoided, leakage of oil from the injection port 9 can be prevented after the fire extinguishing of the burner 8.

Detailed Description of the Invention (Industrial Application Field) The present invention is a method for preventing oil leakage from an oil injection port during extinguishing of a gun-type burner that sprays and burns fuel oil such as kerosene from a bypass nozzle. It is related to.

(Prior Art) As a gun type burner using a bypass nozzle, there is one shown in FIG. 3, for example. This burner a is provided with a bypass nozzle b as an oil spray nozzle, and the oil sprayed from the injection port C is ignited and burned by discharge from a spark plug d.

Oil for spraying is stored in an oil tank e and is supplied to the nozzle b via an oil supply line f, pressurized by an electromagnetic pump g. A part of the oil supplied to the nozzle is sprayed from the injection port C, but the remaining part is returned to the bypass system path, passes through the electromagnetic proportional control valve i and the electromagnetic shut-off valve j, and becomes oil. It flows into the supply line f and is again supplied to the nozzle b by the electromagnetic pump g.

The electromagnetic proportional control valve i can linearly change the opening degree by changing the voltage applied to its excitation coil (not shown), and by controlling this,
The amount of oil returned from the nozzle b to the bypass path, and therefore the amount of combustion of the burner a, can be adjusted steplessly over a wide range.

ためのものである。
Since the electromagnetic on-off valve j does not have a check mechanism in the electromagnetic proportional control valve i, for example, the oil tank e is connected to the electromagnetic proportional control valve i.
If the electromagnetic pump g is stopped when the burner a is extinguished, the oil in the oil tank e will flow back into the bypass system path, and the electromagnetic proportional control valve i will not be able to operate with only the electromagnetic proportional control valve i. This is to prevent this from occurring, as it flows into the nozzle b through the nozzle b and then leaks out from the injection port C.

Conventionally, oil leakage from the injection port C when the burner a is extinguished is prevented by closing the electromagnetic on-off valve j at the same time as the electromagnetic pump g is stopped.

(Problem to be Solved by the Invention) As described above, in the conventional method, the electromagnetic on-off valve j is closed at the same time as the electromagnetic pump g is stopped.
From nozzle b, electromagnetic proportional control valve i, and electromagnetic on-off valve j
There is a problem in that the output pressure of the electromagnetic pump g remains in the system leading to the pump g, which is not shown in the shaded area A of the time chart in Figure 4, and this residual pressure causes oil to leak from the injection port C. .

The present invention aims to solve such problems.

(Means for Solving the Problems) Means for solving the problems described above will be explained based on FIGS. 1 and 2 corresponding to Examples.
A bypass nozzle 1 is provided as an oil spray nozzle, and a bypass line 2 of this nozzle 1 is connected to an electromagnetic pump 6 of an oil supply line 5 to the bypass nozzle l via an electromagnetic proportional control valve 3 and an electromagnetic on/off valve. In the gun type burner 8 which has returned to its proper position on the upstream side of the oil tank 7 and downstream of the oil tank 7,
When extinguishing the burner 8, the electromagnetic on-off valve 4 is closed after an appropriate amount of time has elapsed after stopping the electromagnetic pump 6.

(Operation and Examples) When extinguishing the burner 8, when the electromagnetic pump 6 is stopped while the electromagnetic on-off valve 4 remains open, the electromagnetic pump 6 supplies the nozzle 1, the electromagnetic proportional control valve 3, the electromagnetic on-off valve 4, and the oil supply. Since the yarn path leading to the system 5 is in communication, the oil output pressure of the electromagnetic pump 6 escapes to the oil tank and rapidly attenuates as shown by the shaded area A in the time chart 1- in FIG.

このようにして、電磁ポンプ6の出力圧が充分に減衰し

In this way, if the electromagnetic on-off valve 4 is closed after a period of time has elapsed for the output pressure of the electromagnetic pump 6 to sufficiently attenuate and there is no need to worry about oil leaking from the injection port 9 of the nozzle l, then after the burner 8 is extinguished. No oil leakage occurs from the injection port 9.

(Effects of the Invention) As described in Part 2, the method of the present invention can effectively prevent oil leakage from the nozzle injection port when extinguishing a gun-type burner using a bypass nozzle, thereby preventing the generation of residual flames. This has the effect of reducing wasteful oil consumption.
