Abstract
The invention discloses a U-shaped pipe used for an air duct heater, and relates to the technical field of heating devices. The U-shaped pipe comprises a U-shaped pipe body. A transverse connector and a longitudinal connector I perpendicular to the transverse connector are arranged at one end of the U-shaped pipe body, and a longitudinal connector II and a perpendicular connector perpendicular to the longitudinal connector II are arranged at the other end of the U-shaped pipe body. A blocking piece which can freely move is arranged in the transverse connector. A heating exchanger is arranged at the bent position of the U-shaped pipe body. The U-shaped pipe is reasonable in design and simple in structure, the defects that connectors of an existing U-shaped pipe are not enough and heat exchange can not be controlled are overcome, the fluid heat conveying can be adjusted through the heat exchanger and the blocking piece, and therefore the adaptability of the U-shaped pipe can be improved, and use is convenient.
Description
Technical field
The present invention relates to firing equipment technical field, particularly relate to a kind of duct insert heater U-shaped pipe.
Background technology
Air duct type electric heater is mainly used in the air heat in air channel, and specification is divided into low temperature, middle temperature, high temperature three kinds of forms, and something in common structurally adopts steel plate to support electrothermal tube to reduce the vibration of electrothermal tube, all ultra-temp. control device is housed in terminal box.Another in control except overtemperature prote is housed, also between blower fan and heater, install linkages additional, to guarantee that electric heater starting must after blower fan starts, a differential pressure device is added before and after heater, in case fan trouble, the gas pressure of pathway heater heating generally more than 0.3Kg/cm2, as exceeded above pressure, should please not select circulation heater; Low form heater air heating maximum temperature is no more than 160 DEG C; Middle warm type is no more than 260 DEG C; High temperature modification is no more than 500 DEG C.
But a lot of coupling part of electric heater is connected by different junction blocks, general joint connects inconvenient, existing U-shaped interface tube very little, arranges also unreasonable, and heat energy conveying is inconvenient, energy loss is large, and former U-shaped interface tube is not enough, and the uncontrollable defect of heat exchange.
Summary of the invention
For solving above-mentioned technological deficiency, the object of the invention is to provide a kind of duct insert heater U-shaped pipe.
The solution of the present invention is as follows: a kind of duct insert heater U-shaped pipe, comprise U-shaped tube body, described U-shaped tube body one end end is provided with horizontal interface and the longitudinal interface I vertical with horizontal interface, and the other end is provided with longitudinal interface II and the vertical joint vertical with longitudinal interface II; The jam that setting can be freely movable in horizontal interface; U-shaped tube body bending place is provided with heat exchanger.
Described jam is fixed with the screw front end on the adjustable ring be arranged on outside U-shaped tube body.
The present invention is reasonable in design, and structure is simple, changes former U-shaped interface tube not enough, and the uncontrollable defect of heat exchange, can be regulated the transmission of fluid heat, the using adaptability of this U-shaped pipe is increased by heat exchanger and jam, and easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein: 1, U-shaped tube body; 2, horizontal interface; 3, adjustable ring; 4, longitudinal interface I; 5, longitudinal interface II; 6, vertical joint; 7, heat exchanger; 8, jam.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, a kind of duct insert heater U-shaped pipe, comprise U-shaped tube body 1, described U-shaped tube body 1 one end end is provided with horizontal interface 2 and the longitudinal interface I4 vertical with horizontal interface 2, and the other end is provided with longitudinal interface II5 and the vertical joint 6 vertical with longitudinal interface II5; The jam 8 that setting can be freely movable in horizontal interface 2; U-shaped tube body 1 bending place is provided with heat exchanger 7.
Described jam 8 is fixed with the screw front end on the adjustable ring 3 be arranged on outside U-shaped tube body 1.
Although give detailed description and explanation to the specific embodiment of the present invention above; but what should indicate is; we can carry out various equivalence according to conception of the present invention to above-mentioned embodiment and change and amendment; its function produced do not exceed that description contains yet spiritual time, all should within protection scope of the present invention.
