Abstract

A connection structure of pipes of heat exchanger of gas water heater comprises a water inlet pipe, a water outlet pipe, a U-shaped pipe, a straight pipe, and a welded ring. The water inlet pipe, water outlet pipe, U-shaped pipe are respectively sleeved on the straight pipe. A flaring is disposed on one end of the connection part, and a block is disposed on the other end of the connection part, whereby the flaring is cooperated with the block. The welding ring is fixed on the circular cavity constituted by the inner wall of the flaring, block and the outer wall of the inner connecting pipe of the sleeved pipes, which can solve the problems such as lack of weld and uneven weld caused by the loss of the solder on the welding part of the water inlet pipe, water outlet pipe, U-shaped pipe and straight pipe. The firmness of the solder can be enhanced, and the quality as well as appearance of the products can be improved.

Summary of the invention: technical problem to be solved in the utility model is that the syndeton between the pipe fitting in a kind of gas heater heat exchanger will be provided, it can solve water inlet pipe, outlet pipe, U type pipe effectively and produce Lou weldering and welding non-uniform phenomenon in the loss of weld solder with straight tube respectively, improve the firm degree of soldering, improve the quality and the outward appearance of product.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises water inlet pipe, outlet pipe, U type pipe, straight tube, weld-ring, described water inlet pipe, outlet pipe, U type pipe carry out socket with straight tube respectively, the mouth of pipe of junction one end is provided with enlarging, the other end is provided with block, in the annular chamber that the outer wall three of pipe constituted in described block and enlarging coupling, described weld-ring were fixed in inwall, block and the socket pipe fitting of enlarging.
The mouth of pipe of straight tube is located in described enlarging, and described block is located at respectively on water inlet pipe, outlet pipe, the U type pipe.
Described block is a heading.
The mouth of pipe of water inlet pipe, outlet pipe, U type pipe is located in described enlarging respectively, and described block is located at the outer cover of heat exchanger limit.
Described water inlet pipe, outlet pipe, U type pipe, straight tube are that stainless steel material is made.
Described water inlet pipe, outlet pipe, U type pipe, straight tube are that copper or Cu alloy material are made.
Described water inlet pipe, outlet pipe, U type pipe, straight tube are made for the aluminum or aluminum alloy material.
By soldering processes water inlet pipe, outlet pipe, U type pipe are connected in one with straight tube respectively.
The utility model is compared the beneficial effect that is produced with background technology:
1, the utility model provides the syndeton between the pipe fitting in a kind of gas heater heat exchanger, owing to increased enlarging and block in the junction of pipe fitting and both are matching structure, liquid solder in the soldering termination process after the fusing flows to heat exchanging water pipe's fit clearance, so it can solve water inlet pipe, outlet pipe, U type pipe effectively and produce weldering in the loss of weld solder with Louing and weld non-uniform phenomenon with straight tube respectively, improve the firm degree of soldering, improve the quality and the outward appearance of product.
