Abstract

The utility model provides an air collection pipe component, has the gas collection to be responsible for and the gas collection branch pipe, the gas collection is responsible for and is connected with gas collection branch pipe vertical welding, it has the through -hole to open on the pipe wall that the gas collection was responsible for, the drill way of through -hole has the turn -ups, the gas collection branch pipe one end mouth of pipe has two extend portion, and welded connection is responsible for together in the turn -ups outside and with the gas collection to this mouth of pipe cover. The outer diameter phi 1 that the gas collection was responsible for and the outer diameter phi 2 of gas collection branch pipe satisfy the relational expression between the two: 1.1 2 >= phi of phi, 1 >= 0.9 phi 2, the orificial border of gas collection branch pipe one end line is the shape of a saddle. The utility model discloses welding strength has effectively been strengthened, moreover the welded connection of applicable pipe in the same pipe diameter or close pipe diameter. And simultaneously, the utility model discloses owing to being that welded connection is responsible for together to gas collection branch pipe one end mouth of pipe cover outside the turn -ups and with the gas collection, can make the aperture change of junction through -hole very little, therefore it is less to the flow reduction range of refrigerant, refrigeration effect is better.

Description

A kind of collecting pipe component

Technical field

The utility model relates to a kind of air-conditioning duct, is specifically related to a kind of collecting pipe component for air-conditioning.

Background technology

At present, collecting pipe component more and more adopts vertical linkage arrangement, and connect with the pipe vertical welding reaching close external diameter, Zai Fenji road is circulation separately.And the collecting pipe component be connected with heat exchanger, as shown in Figure 4, primarily of being welded in the through hole inserting gas collecting main pipe vertical after gas-collecting branch pipe reducing.But this connected mode needs first gas-collecting branch pipe to be carried out reducing process, weld strength is not high, and pipe internal diameter after reducing diminishes, and adopts this connected mode to reduce amplitude to the flow of cold-producing medium comparatively large, affects refrigeration.

Summary of the invention

It is high that the purpose of this utility model is to provide a kind of weld strength, reduces amplitude less, the better collecting pipe component of refrigeration to the flow of cold-producing medium.

To achieve these goals, the technical solution of the utility model is: a kind of collecting pipe component, there is gas collecting main pipe and gas-collecting branch pipe, described gas collecting main pipe is connected with gas-collecting branch pipe vertical welding, the tube wall of described gas collecting main pipe has through hole, its improvement is: the aperture of described through hole has flange, described gas-collecting branch pipe one end mouth of pipe has two extensions, and this mouthpiece cover is welded together with gas collecting main pipe outside flange.

In technique scheme, the outside dimension Φ of described gas collecting main pipe ₁with the outside dimension Φ of gas-collecting branch pipe ₂meet relational expression between the two: 1.1 Φ ₂>=Φ ₁>=0.9 Φ ₂.

In technique scheme, the edge line of described gas-collecting branch pipe one end mouth of pipe is the shape of a saddle.

The good effect that the utility model has is: because the aperture of junction through hole has flange, gas-collecting branch pipe one end mouth of pipe has two extensions (edge line of the mouth of pipe is the shape of a saddle), this mouthpiece cover is outside flange and be welded together with gas collecting main pipe, thus effectively strengthen weld strength, and be applicable to being welded to connect of pipe of identical or close caliber.Simultaneously, prior art needs to carry out reducing process to gas-collecting branch pipe and just can insert in the aperture of through hole, the internal diameter of junction through hole is changed greatly and causes the flow of cold-producing medium reduction amplitude larger, on the contrary, the utility model is owing to being that gas-collecting branch pipe mouthpiece cover is outside flange, thus the varying aperture of junction through hole is very little, and reduce amplitude to the flow of cold-producing medium less, refrigeration is better.

Fig. 2 is schematic top plan view of the present utility model;

Fig. 3 is that master of the present utility model looks cross-sectional schematic;

Fig. 4 is that the master of prior art looks cross-sectional schematic.

Detailed description of the invention

Below in conjunction with accompanying drawing and the embodiment that provides, the utility model is further described.

As shown in Figure 1, 2, 3, a kind of collecting pipe component, there is gas collecting main pipe 1 and gas-collecting branch pipe 2, described gas collecting main pipe 1 is connected with gas-collecting branch pipe 2 vertical welding, the tube wall of described gas collecting main pipe 1 has through hole 3, it is characterized in that: the aperture of described through hole 3 has flange 1-1, described gas-collecting branch pipe 2 one end mouth of pipe has two extension 2-1, and this mouthpiece cover is welded together with gas collecting main pipe 1 outside flange 1-1.

As shown in Figure 1, 2, 3, the outside dimension Φ of described gas collecting main pipe 1 ₁with the outside dimension Φ of gas-collecting branch pipe 2 ₂meet relational expression between the two: 1.1 Φ ₂>=Φ ₁>=0.9 Φ ₂.Thus the utility model be specially adapted to two outside dimensions close to and being welded to connect of the pipe be more or less the same.

As shown in Figure 1, the edge line of described gas-collecting branch pipe 2 one end mouth of pipe is the shape of a saddle.

The collecting pipe component of following specific embodiment 1, embodiment 2 can be obtained by table 1:

Table 1:
