Description

Stainless steel connecting pipe assembly

Technical Field

The utility model relates to a refrigeration annex technical field, more specifically say and relate to a connecting pipe subassembly of stainless steel.

Background

The air conditioning system is applied to connecting pipes in a large number, and the air conditioning system has the following effects that four air conditioning parts are used: the compressor, the condenser, the evaporator and the throttling device are connected to form a loop. At present, red copper is basically used. However, as the price of nonferrous metals such as red copper and the like continuously rises, the stainless steel replacing the red copper has become common knowledge in the air conditioning industry, particularly for pipelines which only play a connecting role, the requirement on the material is not very high, and the use of the stainless steel replacing the red copper becomes more meaningful. Typically, the system lines will include other auxiliary components such as fill valves, pressure switches, process tubes, etc. When adopting the full copper pipeline before, only need be responsible for on drill hole can, the customer can be very convenient with above-mentioned spare part with be responsible for the welding, but change into behind the stainless steel, the welding of implementation stainless steel that the customer can't be light and red copper.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a need not drilling, connect convenient stainless steel's connecting tube subassembly to the not enough of prior art.

A stainless steel connecting pipe assembly comprises a main pipe, wherein connecting pipes are arranged at two ends of the main pipe, and a plurality of transition pipes are sleeved on the main pipe; the two sides of the transition pipe are provided with bulges, the main pipe is provided with a lug boss communicated with the opening of the inner hole, and the bulges are abutted against the lug boss; the connecting pipe and the transition pipe are made of red copper. Need not to punch and can connect, be responsible for and transition pipe location convenience, firm in connection. And the customer can conveniently connect other parts.

As a further improvement and supplement to the above solution, the present invention further comprises the following additional technical features:

the boss is of a hole-pulling and flanging structure and of an integrated structure, welding is not needed, and the structure is reasonable.

The transition pipe is of a straight cylinder type, a necking type or a flaring type structure, and has a wide application range.

The main pipe is made of stainless steel, and the cost is low.

The main pipe, the connecting pipe and the transition pipe are brazed by adopting a tunnel furnace or high-frequency induction, and the connection is convenient and firm.

Use the utility model discloses following beneficial effect can be reached: the main pipe is made of stainless steel, so that the production cost is reduced. Be responsible for and set up and pull out hole flanging structure, the transition pipe sets up the arch, and the location is convenient, firm in connection. Through the connecting pipe made of red copper, welding of a client and a system pipeline is facilitated. Set up the transition pipe of red copper material, make things convenient for the customer to connect some other auxiliary components, if fill valve, pressure switch, the butt joint of red copper and red copper is directly carried out to the technology pipe, also need not to punch.

Detailed Description

The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1-8, the present invention is a stainless steel connector tube assembly.

The connecting pipe component of stainless steel described in this embodiment, including being responsible for 3, the material of being responsible for 3 is the stainless steel, and the shape of being responsible for 3 can be the return bend, also can be the straight tube, and the shape of return bend needs the installation that adapts to the customer, accomplishes not to interfere. At a suitable position of the stainless steel main pipe 3, a hole drawing and flanging are carried out to form a boss 31 communicated with the opening of the inner hole so as to connect the transition pipe 2 with the boss.

The main pipe 3 is provided with a connecting pipe 1, the connecting pipe 1 is made of red copper, and the connecting pipe is used for connecting the main pipe 3 of the stainless steel with a welded part and is arranged at two ends of a pipeline part. The butt joint of the red copper and the red copper is convenient for customers to use the red copper material. The interface size of the take-over 1 can be adapted according to the customer's configuration.

Be responsible for 3 and go up many places covers and be equipped with transition pipe 2, transition pipe 2 materials be red copper, generally, can set up some other auxiliary component on the system pipeline, like filling valve, pressure switch, technology pipe etc.. When adopting full copper pipeline before, only need be responsible for 3 go on drill holes can, the customer can be very convenient with above-mentioned spare part with be responsible for 3 welding, nevertheless change into behind the stainless steel, because the unable easy implementation stainless steel of customer and red copper's welding, so need design a transition pipe 2, make things convenient for customer's welding.

Two pairs of sides are equipped with arch 21 on the transition pipe 2, and arch 21 is the arc structure, and arch 21 and boss 31 are supported and are leaned on, and location and connection are convenient.

Further, the transition pipe 2 is of a straight cylinder type, a reduced mouth type or a flaring type structure, which is mainly used for adapting to different interface sizes.

Furthermore, the main pipe 3, the connecting pipe 1 and the transition pipe 2 are brazed by a tunnel furnace or high-frequency induction, and the solder can be tin bronze solder or brass solder.

When the stainless steel connecting pipe assembly is used, one end of the connecting pipe 1 is connected with a main pipe 3 of the stainless steel, and the other end is reserved for a customer to be welded with a system pipeline. The transition duct 2 is connected to some other auxiliary components, such as filling valves, pressure switches, process ducts, etc.

The above is the preferred embodiment of the present invention, and the protection scope of the present invention is not limited, and the deformation and improvement made by the design idea of the present invention for those skilled in the art should be considered as the protection scope of the present invention.
