Description
Technical field
The utility model is a kind of floating ball preventing dry burning device of boats and ships oil intensification electric heater.
Background technique
If the fuel oil heavy oil that uses on the boats and ships, heavy oil heat temperature raising that need viscosity is big is to reach combustion requirements; When temperature is low, use lubricant oil, lubricant oil heat temperature raising that need viscosity is bigger is to reach lubrication effect.The oil intensification heater of common use on the boats and ships is to adopt electric heater, cold oil is heated into deep fat after, deliver to the place that needs and go.The temperature of electric heater is to show, regulate, control with temperature controlling instrument.But do not have oil when running in not defeated full oil pocket cylindrical shell of cold oil or the oil pocket cylindrical shell, at this moment, electric heater just is in dry-fire condition, if temperature controlling instrument is malfunctioning, and the accident of will blasting.Adopt the dry burning preventing device of heat responsive element, can play the effect of dry combustion prevention, but when the defeated full oil of oil pocket barrel; Not dry-fire condition, because the oil temperature is higher, when reaching the heat responsive element setting temperature; Heat responsive element also can move, the electric heater outage, and oil can not get heating.If the setting temperature of heat responsive element is higher, cold oil is failed in the full oil pocket cylindrical shell or is not had oil in the oil pocket cylindrical shell, and when being in dry-fire condition, heat responsive element can not move, and electric heater continues energising, carries out dry combustion method, the accident of will blasting.
Summary of the invention
The utility model technical problem to be solved: be that a kind of floating ball preventing dry burning device for the boats and ships oil intensification electric heater that prevents explosive accident will be provided.
For solving the technological scheme that above technical problem adopts is such: to horizontal oily intensification electric heater, side is adorned ball float housing off-centre is welded on electric heater oil pocket cylindrical shell right-hand member, fluid through eccentric side charge of oil mouth into and out of side dress ball float housing.In the side dress ball float housing the microscler ball float of heat resisting and pressure resisting is installed, when pasta rose, microscler ball float head was because of floating function; Move upward around ball lever, when reaching 11 degree angles, horizontal oily intensification electric heater is that horizontal electrical heating elements is initially located in the normal heating state; Magnetic reed switch in the wire connection cavity receives the influence of arm end magnet, makes " often opening " contact become " normally closed " contact, the energising of side wiring road; Horizontal electrical heating elements is connected, and begins heating; When pasta descended, microscler ball float head moved downward around ball lever because of floating function; When reaching 11 degree angles; Horizontal oily intensification electric heater is that horizontal electrical heating elements is initially located in dry-fire condition, and " normally closed " contact becomes " often opening " contact, horizontal electrical heating elements down circuitry; Stop heating, prevent dry combustion method.Vertical oily intensification electric heater is taken over the vertical oil pocket cylindrical shell of connection and is pushed up dress ball float housing with two hollows, and fluid is adorned the ball float housing through two hollows adapters into and out of the top.In the dress ball float housing of top the circular ball float of upper and lower two heat resisting and pressure resistings is installed, there is ring magnet circular ball float hollow and inside, in airtight non-magnetic pipe, dry reed-pipe are installed; When pasta rose, circular ball float rose because of floating function, when reaching a certain position; Vertical oily intensification electric heater is that vertical electrical heating elements is in the normal heating state, and dry reed-pipe produces the effect of adhesive, output " closure " signal; Vertical electrical heating elements circuit is connected, and begins heating; When pasta descended, circular ball float descended because of floating function, when reaching a certain position; Vertical oily intensification electric heater is that vertical electrical heating elements is initially located in dry-fire condition; Dry reed-pipe produces the action of " disconnection ", output " disconnection " signal, and vertical electrical heating elements circuit breaks off; Stop heating, prevent dry combustion method.Upper and lower two circular ball floats, the dress ball lever descends or rises along the top, so that keep the action of " disconnection " or " closure ".
Dismounting, when changing the electrical heating elements of boats and ships oil intensification electric heater, to horizontal electric heater, the dismounting of electrical heating elements along continuous straight runs; Vertical electric heater, electrical heating elements is dismounting vertically.In the equipment compartment of boats and ships, the space is less, and the space that electric heater is installed is limited.For saving the space, the dismounting of float-ball type dry burning preventing device ball float also should be consistent with the direction of electrical heating elements dismounting.To horizontal electric heater, require the dismounting of ball float along continuous straight runs; Vertical electric heater requires vertically dismounting of ball float.The floating ball preventing dry burning device of the utility model is unscrewed or is tightened flange bolt, dismounting ball float easily just, and the dismounting direction meets above-mentioned requirements.
Adopt above technological scheme, its effect is conspicuous:
1, effectively prevent the dry combustion method explosive accident: need only in the electric heater oil pocket cylindrical shell when oil starvation taking place or not having oil, this device can break off the electrical heating elements power supply, prevents dry combustion method safely, reliably.
2, heat resisting and pressure resisting: this device can bear 200 ℃ of temperature and 3Mpa pressure.
3, ball float easy accessibility, and dismounting direction meets requirement peculiar to vessel.
