Abstract
The invention relates to an electric heater unit used in a water pipe, relating to the technical field of freeze protection by means of electric boosting heating The electric heater unit mainly comprises an internal electric heater (2), a support frame (3), an electric wire (4), a temperature sensor (5), a temperature controller (6), etc. When the temperature sensor (5) senses that the water temperature in the water pipe 1 falls to approach the freezing point, the temperature controller (6) is turns on the internal electric heater (2) to heat the water in the water pipe (1), so that the water pipe (1) is prevented from being damaged by frozen water. Compared with the ways of laying an electric tracing belt outside a pipe, and the like, the invention has the advantages that the heat energy generated by the electric heater unit inside the pipe can be completely transmitted into the cold water, and the work environment in the water pipe is stabler than that outside the pipe, so that the service life of the electric heater unit can be prolonged, and the internal electric heater (2) is easier to be maintained and replaced by being placed inside the water pipe (1) than being placed outside the water pipe (1).
Description
Technical field:
The present invention relates to the especially interior electric heater unit of water pipe of a kind of electric heater unit.
Background technology:
Usually can make outdoor water pipe freezing the severe winter in the north, the auxiliary heating and anti-freezing mode of present electricity is the outer electric-heating belt that lays of pipe, but electric-heating belt can not pass to heat energy 100% ground the interior water of pipe and cause waste of electric energy like this, and because is sandwiched in water pipe and middle not easy care and the replacing of heat insulating material.
Summary of the invention:
A kind of electric heating apparatus in water pipe, it relates to the auxiliary heating and anti-freezing technology of electricity of water pipe, mainly is made up of electric heater, electric wire, temperature pick up, bracing frame, temperature controller in the pipe.Electric heater is arranged at water pipe inside, a temperature pick up that contacts with water in the water pipe is set in pipe again, the water temperature signal that temperature controller records with temperature pick up is as electric heater being carried out control foundation such as switch.For electric heater is directly contacted with pipe inner wall, with several bracing frames with the electric heater frame in the middle of water pipe, bracing frame does not hinder water and flows through simultaneously.When recording water temperature, temperature pick up is reduced to when freezing temperature, the signal that temperature controller root temperature pick up transmits, open electric heater in the pipe, electric heater is started working in the pipe, water temperature raises in the water pipe, when temperature pick up records water temperature and is elevated to safe temperature, i.e. can not freeze in the short time, the circuit of electric heater disconnected in temperature controller will be managed.
Description of drawings:
Fig. 1 has illustrated the schematic diagram of electric heating apparatus in water pipe, and Fig. 2 is its sectional view.
1: water pipe; 2: electric heater in the pipe; 3: bracing frame; 4: electric wire; 5: temperature pick up;
6: temperature controller; 7: pipe inner wall; 8: control.
The specific embodiment:
Electric heater unit in a kind of water pipe mainly is made up of electric heater 2, bracing frame 3, electric wire 4, temperature pick up 5, temperature controller 6 in the pipe.Electric heater 2 is selected MI heat production cable for use in the pipe, increases the service life under the prerequisite of guaranteed performance and its straightness accuracy preferably in pipe.At first bracing frame 3 is inserted on the electric heater, the two enters water pipe 1 together, make that electric heater 2 directly contact with pipe inner wall 7 in the pipe, every a segment distance bracing frame 3 is set on the electric heater 2 in pipe, several bracing frames 3 can be middle in water pipe 1 with 2 of the interior electric heaters of pipe; In isolated tube, accomplish not hinder flowing of water in the electric heater 2 for bracing frame 3.The interior electric heater 2 of diameter compensating pipe that increases water pipe 1 takes up space.A temperature pick up 5 is set in water pipe 1 again,, the control foundation is provided for temperature controller 6 in order to water temperature in the automatic measurement water pipe 1.To record water temperature normal when temperature pick up 5, promptly water temperature be higher than the temperature that freezes (can be made as 5 degrees centigrade voluntarily), in the time of can not freezing water pipe 1 in the short time, temperature controller 6 is not to electric heater 2 any operations in managing; Cross low when freezing temperature (can limit is 4 degrees centigrade) when temperature pick up 5 records water temperature, temperature controller 6 control power supplys 4 are opened, electric heater 2 is started working in the pipe, water temperature raises gradually, when temperature pick up 5 records water temperature again when freezing temperature, temperature controller 6 controls power supply 4 again and cuts out, and electric heater 2 quits work in the pipe.
Electric heater 2 was arranged on the inside of water pipe in the present invention will manage, and compared with the electric-heating belt that present outside is laid, and advantage and innovation part are: the first, and the heat energy that electrical heating 2 produces in the pipe can pass to cold water in 100% ground; The second, it is stable outward that the aspect working environments such as the temperature difference in the water pipe are compared water pipe, so just can prolong the application life of electric heater 2 in the pipe; The 3rd, electric heater (2) places water pipe (1) inside in will managing, and does not destroy to be convenient to maintenance under the situation of insulation layer and to change.
Claims (3)
1, a kind of electric heating apparatus in water pipe mainly is made up of electric heater (2), bracing frame (3), electric wire (4), temperature pick up (5), temperature controller (6) in the pipe.It is characterized in that:
Electric heater (2) is in the inside of water pipe (1) in the pipe, and electric heater (2) is supported by bracing frame (3) in the pipe.
2, a kind of electric heating apparatus in water pipe according to claim 1 is characterized in that:
Electric heater (2) was positioned between water pipe (1) and the electric heater (2) in bracing frame (3) will be managed, and contacted with the two.
