Abstract
The utility model discloses a safety controller of thermal oil-stove, which belongs to the safety facility of thermal furnace. Oil supply and oil return lines of the thermal oil-stove are provided internally with electromagnetic valves and replacement oil circuits for cold oil; and an electromagnetic valve and an additional oil circuit are arranged between a low oil storage groove and a circulating pump, and an oil-level control switch of floating ball is arranged in a high oil storage groove; an inlet of oil stove is provided with an automatic flowmeter for controlling the closure of each electromagnetic valve. When power down or shortage of oil supply occurs, the supplementary and replacement device of cold oil is started up automatically to effectively control the coking of pipe wall produced by decomposition of oil due to fast rising of oil temperature, and supplements automatically thermal oil to safe liquid level when power supply comes back so as to ensure safe circulating and running of device and reduce loss.
Description
Technical field
The utility model belongs to heating stove safety devices scope, particularly a kind of heat-conducting oil furnace safety control.
Technical background
Heating boiler generally with water or steam as the medium medium, heat energy is offered the hot equipment of using, be that last decade just occurs with oil as the heating stove of medium medium because operating pressure is low, general enterprise pays little attention to safely it, accident is continuous every year.Because general heat-conducting oil furnace only is provided with attemperating unit, the flow that manual cold oil is replaced the heat-conducting oil furnace that is in operation does not ensure, be in the low discharge operation for a long time, cause too high, the decomposition of oil product temperature, manual cold oil is replaced needs 15-20 minute, causes warm rapid rising of oil in the heating furnace, surpass decomposition temperature, coking carbon deposit on furnace wall causes oil circuit to block, and has an accident.
Summary of the invention
The purpose of this utility model provides a kind of heat-conducting oil furnace safety control.It is characterized in that: at first with the by-passing valve 14 between oil feed line 15 and the return line 13 by manually changing magnetic valve into, and magnetic valve 12 is installed, and between heat-conducting oil furnace 16 oil-outs and low level oil storage tank 1, connect cold oil displacement pipeline 9 and magnetic valve 8 between heat-conducting oil furnace 16 oil-outs of oil feed line 15 and by-passing valve 14; Between return line 13 and triple valve 5, install magnetic valve 11 additional, and oil level float switch 7 is installed in high-order oil storage tank 4, also at heat-conducting oil furnace 16 oil-in places, the automatic oil mass flowmeter 10 of induction type is installed in addition, low level oil storage tank 1 and circulating pump 6 are communicated with by additional line 2 and magnetic valve 3.
The beneficial effect 1. that the utility model reaches is opened and closed by the automatic oil mass flowmeter control of induction type bypass solenoid valve, and the oil inlet quantity of the oil-in of heat-conducting oil furnace is remained in the setting range, and the whole system systemic circulation is normally moved.2. by being installed in oil feed line and return line, and the magnetic valve on the additional line and oil level float switch have been formed, and cold oil is replaced automatically, auto-feeding device.When taking place to have a power failure, the hot equipment of automatic disconnection starts cold oil displacement and additional oil circuit automatically automatically, replenishes cold oil rapidly and replace in the oil guide pipe of heat-conducting oil furnace.Guarantee that oily Wen Buhui raises rapidly in the heat-conducting oil furnace, controlled generation because of oil decomposition coking carbon deposit phenomenon on tube wall.The incoming call back replenishes conduction oil automatically to safe liquid level.
Description of drawings
Fig. 1 is a heat-conducting oil furnace safety control structural representation.
The specific embodiment
Figure 1 shows that heat-conducting oil furnace safety control structural representation.This heat conduction oil circuit safety control is: at first with the by-passing valve 14 between oil feed line 15 and the return line 13 by manually changing magnetic valve into, and magnetic valve 12 is installed between heat-conducting oil furnace 16 oil-outs of oil feed line 15 and by-passing valve 14, and between return line 13 and triple valve 5, install magnetic valve 11 additional, be convenient to when having a power failure, automatically consumer 17 and heat-conducting oil furnace 16 are disconnected, magnetic valve 8 on the displacement of the cold oil between heat-conducting oil furnace 16 oil-outs and the low level oil storage tank 1 pipeline 9 is opened simultaneously, carries out the cold oil displacement.Control oil temperature is returned and is fallen rapidly, guarantees below decomposition temperature, avoids heat-conducting oil pipes inwall coking carbon deposit.During incoming call, open the magnetic valve 3 on the additional line 2 automatically, open magnetic valve 11,12, close magnetic valve 8.And oil level float switch 7 is installed in high-order oil storage tank 4, and the automatic oil mass flowmeter 10 of induction type is installed at heat-conducting oil furnace 16 oil-in places, control opening or closing of magnetic valve 14, the flow of guaranteeing oil in the stove is within setting range.
