Detailed Description
The invention is described in detail below with reference to the drawings and examples of the specification:
fig. 1 to 8 are schematic views illustrating an embodiment of a fabricated air conditioner branching pipe according to the present invention.
The assembled air conditioner branching pipe comprises a three-way pipe 1 and a branch pipe component 2, wherein each pipe orifice of the three-way pipe 1 is in threaded connection with the branch pipe component 2.
The three-way pipe 1 is a y-shaped three-way pipe 1.
The outer wall surface of each pipe orifice of the three-way pipe 1 is provided with an external thread 11, and the branch pipe component 2 comprises a branch pipe 21 and a nut component 22 which is sleeved on the periphery of the branch pipe 21 and is in threaded connection with the external thread 11 of the pipe orifice of the three-way pipe 1; the front end port of the branch pipe 21 is a connecting port 211 which is integrally processed and is horn-shaped, the inner wall surface of the connecting port 211 of the branch pipe 21 is attached to the outer wall surface of the edge of the pipe orifice of the three-way pipe 1, and the branch pipe 21 is connected with the three-way pipe 1 by screwing the nut member 22 with the pipe orifice of the three-way pipe 1.
The trumpet-shaped connection port 211 of the front end port of the branch pipe 21 can be manufactured in real time by using an expander on the air conditioner installation construction site. The manufacturing method of the branch pipe 21 comprises the following steps: cutting a roll of copper tube at a proper position to obtain a copper tube with a required length for manufacturing the branch tube 21, and then expanding one end of the cut copper tube by using an expander to form a horn shape, thus obtaining the branch tube 21 with the horn-shaped connecting port 211.
The nut member 22 is axially slidable along the branch pipe 21.
The outer wall surface of the edge of the pipe orifice of the three-way pipe 1 is an inner inclined surface 12 matched with the inclined surface formed by the connecting port 211.
The front end of the nut member 22 is provided with an internal thread 221 matched with the external thread 11 of the pipe orifice of the three-way pipe 1, and the inner wall surface of the rear end of the nut member 22 is an external inclined surface 222 matched with the inclined surface formed by the connecting port 211 of the branch pipe 21.
The inner slope surface 12 and the outer slope surface 222 are defined according to whether the surfaces are attached to the inner wall surface of the connection port 211 or the outer wall surface of the connection port 211. Since the outer wall surface of the nozzle edge of the three-way pipe 1 is in contact with the inner wall surface of the connection port 211, the inclined surface formed by the nozzle edge of the three-way pipe 1 along the outer wall surface is defined as an inner inclined surface 12. Since the inner wall surface of the rear end of the nut member 22 is in contact with the outer wall surface of the connection port 211, the inclined surface formed on the inner wall surface of the rear end of the nut member 22 is defined as an outer inclined surface 222.
The branch pipe 21 and the connecting port 211 of the branch pipe 21 are made of red copper; the three-way pipe 1 and the nut piece 22 are made of brass.
Because the connection port 211 is made of red copper, and the red copper is soft, the horn-shaped connection port 211 can be used as a sealing element, and the whole assembled air conditioner branch pipe does not need to use other sealing elements. The inner wall surface of the connecting port 211 is attached to the outer wall surface of the edge of the pipe orifice of the three-way pipe 1, and the connecting port 211 is tightly attached to the outer wall surface of the edge of the pipe orifice of the three-way pipe 1 under the action of the nut member 22, so that the sealing effect is achieved.
The assembling mode of the assembled air conditioner branch pipe is as follows: firstly, the nut piece 22 is sleeved on the branch pipe 21, then the nut piece 22 is slid to the connecting port 211 of the branch pipe 21, then the inner wall surface of the connecting port 211 of the branch pipe 21 is tightly attached to the outer wall surface of the edge of the pipe orifice of the three-way pipe 1, the nut piece 22 is screwed to connect the pipe orifice of the three-way pipe 1, and then the three-way pipe 1 and the branch pipe member 2 are connected. The pipe orifices of the three-way pipe 1 are connected with the branch pipe components 2 in the above mode.
It should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various changes, improvements and decorations without departing from the scope of the present invention, and these changes, improvements and decorations should be considered as the protection scope of the present invention.
