The circuit structure diagram of Fig. 1, fuel pipe internal heater;
Fig. 2, fuel pipe internal heater integral structure schematic representation;
Fig. 3, circuit construction of electric power figure;
Embodiment
Further explanation in detail in conjunction with the accompanying drawings; 9 are shown fuel pipe among the figure, and arrow is shown fuel oil and flows to;
As shown in Figure 1, the circuit structure of fuel pipe internal heater is to have electrically-heated-wire L, one termination power negative pole, its other end series connection thermal cut-off RD
1Meet bi-metal temperature controller ZK afterwards, another termination positive source of this controller; Described heater welding assembly and injection moulding are packaged as a whole, and power supply is introduced by socket, electrically-heated-wire L then with the detachable property of temperature control circuit link together; When the fuel oil temperature in the fuel pipe is lower than 7 ℃ or when reaching 24 ℃, bi-metal temperature controller ZK then is switched on or switched off power supply automatically, realizes beginning or stops heating, in case bi-metal temperature controller ZK lost efficacy and was in the circuit on-state, at this moment, the interior fuel oil temperature of pipe is if be elevated to thermal cut-off RD
1Fusing-off temperature, its automatically fusing and disconnect heater circuit stops heating, realizes reliable safety protection.
As shown in Figure 2, fuel pipe internal heater integral structure is, the top of the main body 1 of injection moulding packaging body has the circular locating shoulder 2 of evagination, and its upside is close to then power supply introducing joint 3, is exposing thermal cut-off RD respectively on two relative sides of the main body 1 of injection moulding packaging body
1And the surface of the main body of bi-metal temperature controller ZK, so that its correct temperature information that transmits fuel oil, the lower end of the main body 1 of injection moulding packaging body is close to the then circuit jointing 4 of electrically-heated-wire L; Use when being equipped with, described heater inserts in the fuel pipe by the end interface place that three-way interface 5 is contained in fuel pipe, locating shoulder 2 is pressed on the by-pass port of three-way interface 5 by sealing gasket 6, and be fixed by the locking nut on the by-pass port 7, electrically-heated-wire L links together by connector 8 and circuit jointing 4 detachable property; When electrically-heated-wire L double-end type directly was connected with the detachable property of temperature control circuit ground by circuit jointing 4, the fuel pipe internal heater should be contained in the inlet end of fuel pipe, and electrically-heated-wire L prolongs fuel oil and flows to storing in fuel pipe; When the end of electrically-heated-wire L connect power cathode with the ground connection formula of forging iron, electrically-heated-wire L passed through after the fuel pipe and ground connection.Described connector is two-way double-end type socket, in order to the introducing power supply or the connecting circuit of detachable property; Injection moulding must be satisfied anti-fuel oil, high temperature resistant, ageing-resistant and insulation with material, and the intensity height.
As shown in Figure 3, the structure of power circuit is, with power supply on vehicle E interlocking, power supply on vehicle E draws the positive and negative electrode of power supply by power switch DYK, the positive pole fus RD that connects successively
2After the moving together contact interlock switch LSK of relay J, connect the positive pole of bi-metal temperature controller ZK, moving together contact interlock switch LSK prepares the retaining interlocking by the motor of relay J and car key switch DSK, when negative pole is succeeded electrical equipment J, connects the negative pole of bi-metal temperature controller ZK; Using method, earlier power switch DYK is placed the power connection state, afterwards, place motor to prepare retaining car key switch DSK, then the power supply of circuit is promptly connected, bi-metal temperature controller ZK is in running order automatically, prepares retaining as long as car key switch DSK is in motor, and is promptly like this always.
The fuel pipe internal heater generally be fitted in fuel tank in the oil-fired system to 30 microns filter cleaners of precipitator-promptly, precipitator to oil-water separator-promptly 10 microns filter cleaners and oil-water separator to the fuel pipe between the oil transfer pump, and independent respectively temperature automatically controlled and carry out safety protection.
Bi-metal temperature controller ZK produces for the well-informed Electrical Appliances Co., Ltd of Zhejiang Province's Yuyao City, and its operating temperature range is pressed customer requirements and decided.
Thermal cut-off RD1 is that the red valuable Electronics Co., Ltd. in Dongguan, Guangdong produces, and general fusing-off temperature is 100 ℃.
Electrically-heated-wire L is Jiangsu Province's Xinghua City non-conducting material head factory production, and the electrically-heated-wire used of electric mattress roughly the same, its surrounding layer must satisfy anti-fuel oil and high temperature, ageing-resistant and insulation, and the intensity height, below the general 8W/ rice of power; The power of the electrically-heated-wire L of oil pipe internal heater should with corresponding thermal cut-off RD
1Coupling.
