Abstract
The utility model provides a top-pressing double fasten apparatus for tube heat-exchanger composed of a plurality of single branch pipes, which can simultaneously solve the problems of fastening the heat pipes and heat expansion with simple structure. The utility model is convenient in installation and maintenance, which can improve the dismounting efficiency to 5-10 times.
Description
The present invention is a kind of jack unit of being used by the heat exchange of heat pipe that many single arms are formed of only being suitable for.
The jack unit of existing heat exchange of heat pipe is divided into two classes substantially, and a class is that spring pursues the pipe roof pressure; Another kind of is that steel bar divides row roof pressure.The former overlaps a spring on the top of every heat pipe, adds the steel cover above, pushes down the edge of cover in addition with pad, pushes down pad with holding screw again.This apparatus structure complexity, the installation and maintenance trouble, dismounting is inconvenience very, and the latter holes on steel bar earlier, compresses every heat pipe respectively with holding screw in addition.This device can not solve the problem of expanded by heating, and not tightening when cold conditions does not then have pressuring action; If tightening during cold conditions, then hot expansion makes the heat pipe bending.
The invention provides a kind of two-restriction jack unit, simple in structure, can solve tightening heat pipe and thermal expansion problem simultaneously, installation and maintenance are convenient, and removal efficiency can improve 5～10 times, makes easily, and is with low cost.
This explanation is with the schematic diagram of two-restriction jack unit, its concrete structure is that spring (1) is positioned on each heat pipe top earlier, use hole-drilled press strip (2) to be enclosed within every heat extraction tube end again with pressing spring, two ends with press strip (2) are enclosed within respectively on the little axle (3) of heat exchanger shell sidewall top in addition, and carve tightly with carving son (4).
Press 5～20 millimeters deflections in cold conditions during installation, press strip (2) is given be pressed in heat pipe end and tightening; Its dilatancy amount is absorbed by spring (1) when hot, thereby has prevented the heat pipe bending.
For guaranteeing press strip (2) intensity, should adopt the bonding jumper of cast iron or steel construction piece, to make for convenient, its press strip (2) section configuration and size are not limit.
Claims (3)
1, spring (1) jack unit used of a kind of heat exchange of heat pipe, it is fastening to it is characterized in that adopting simultaneously press strip (2) and little axle (3) to carve son (4).
2, a kind of as right 1 described jack unit, it is characterized in that the metal material of its press strip (2) for cast iron or steel construction piece.
3, a kind of as right 1,2 described jack units, it is characterized by press strip (2) section configuration and size and do not limit.
