Abstract
Description
Technical Field
[0001] This application belongs to the technical field of compressor liquid receivers, and particularly relates to a liquid receiver gas pipe. Background Art
[0002] The liquid receiver is an important component of the compressor, which plays the roles of storage, gas-liquid separation, filtration, silencing, and refrigerant buffering. The main structure of the liquid receiver includes a cylinder body, an intake straight pipe and an outlet elbow pipe respectively arranged at both ends of the cylinder body.
[0003] In the prior art, in order to ensure the stability and reliability of the compressor and the liquid receiver pipeline system, the above-mentioned intake straight pipe is usually made of copper. Most of the traditional intake straight pipes are smooth pipes with smooth outer walls, which have problems such as large positioning difficulty and poor concentricity with the cylinder body during assembly with the cylinder body, and additional solder is required during the welding process with the cylinder body, resulting in low production efficiency, high energy consumption and high production cost. Therefore, in the prior art, a welding boss or a welding flange and other structures are provided at one end of the copper pipe body of the intake straight pipe to facilitate the assembly of the intake straight pipe and the cylinder body, and in the prior art, the welding boss or the welding flange and the copper pipe body of the intake straight pipe are usually connected by welding. In the prior art, the intake straight pipe and the outlet elbow pipe are usually also fixedly connected to the intake port and the outlet port at both ends of the cylinder body by welding. That is to say, welding needs to be carried out on both sides of the welding boss or welding flange and other structures at the end of the copper pipe body.
[0004] However, since the axial dimensions of the existing welding boss or welding flange and other structures are small, the welding points of the above two welding processes are too close, and it is easy to damage or directly penetrate the welding point between the welding boss and the copper pipe body during the welding between the welding boss and the cylinder body, thereby causing the structure of the copper pipe body of the intake straight pipe to be damaged and affecting the normal use of the intake straight pipe and the liquid receiver.
[0005] It can be seen that there are still certain defects in the prior art. Utility Model Content

[0039] As Figure 1-8 shown, a liquid storage container gas pipe 1 is disclosed in this application, which includes a pipe body part 11 and a transition part 12 that are axially connected. The transition part 12 includes a first connection section 121 and a second connection section 122. The pipe body part 11 includes a mating section 111 that is matingly connected with the first connection section 121. At least a part of the first connection section 121 is sleeved outside the mating section 111 along the axis. A first limiting part 1111 is provided on the outer wall of the mating section 111, and the port of the first connection section 121 is in limiting cooperation with the first limiting part 1111; a first welding part 1211 for welding connection with the mating section 111 is further provided at the end of the first connection section 121, and a second welding part 1222 for welding connection with the cylinder body is provided at the end of the second connection section 122. Further, referring to Figure 1 and Figure 2 shown, a welding boss 1221 is formed on the outer wall of the second connection section 122. The welding boss 1221 is provided at one end of the second connection section 122 away from the first connection section 121 and the second welding part 1222 is provided on the welding boss 1221.
[0040] In the above solution, by adopting the structures of the first connection section 121 and the second connection section 122, the transition part 12 in this application has a longer axial length, and by respectively arranging the first welding part 1211 and the second welding part 1222 at the ends of the first connection section 121 and the second connection section 122, the distance between the first welding part 1211 and the second welding part 1222 in this application is greatly extended compared with the distance between the two welding points in the previous prior art, thereby effectively avoiding the problem that the welding point between the welding boss 1221 and the copper pipe body is damaged or directly penetrated. At the same time, referring to Figure 8 shown, by extending the axial length of the transition part 12, the length of the pipe body part 11 can be shortened compared with the existing intake straight pipe products without changing the axial length of the intake straight pipe, thereby reducing the consumption of copper materials and being beneficial to reducing the production cost on the premise of ensuring product quality.
[0041] The technical solution of the present application will be further explained and illustrated through two embodiments as follows:
[0042] Embodiment 1: Referring to Figure 1-3 As shown, in this Embodiment 1, the pipe body portion 11 further includes a main body section 112 connected to the mating section 111. A second limiting portion 1212 is further formed on the inner wall of the first connecting section 121. The port of the mating section 111 is in limiting cooperation with the second limiting portion 1212. Along the circumferential direction of the second connecting section 122, a third limiting portion 1223 is provided on the side of the welding boss 1221 away from the first connecting section 121. The third limiting portion 1223 is used for limiting cooperation with the air inlet port of the cylinder body. Through the setting of the second limiting portion 1212 and in cooperation with the foregoing first limiting portion 1111, a two-way limit can be formed on the first connecting section 121 and the mating section 111 in the axial direction, improving the matching accuracy and efficiency between the mating portion and the first connecting section 121. At the same time, through the setting of the third limiting portion 1223, it is convenient for the welding boss 1221 to cooperate with the air inlet port on the cylinder body, which is beneficial to ensuring good concentricity when the air inlet straight pipe is connected to the cylinder body.
[0043] Preferably, continuing to refer to Figure 2 As shown, the third limiting portion 1223 is a limiting step, including an axial limiting portion 12231 extending radially along the second connecting section 122 and a radial limiting portion 12233 extending axially along the second connecting section 122. The axial limiting portion 12231 has a first limiting surface 12232, and the radial limiting portion 12233 has a second limiting surface 12234 connected to the first limiting surface 12232. The first limiting surface 12232 extends radially along the second connecting section 122, and the included angle between the first limiting surface 12232 and the second limiting surface 12234 is an obtuse angle. Along the axial direction of the second connecting section 122, an arc-shaped guiding portion 12235 is provided at one end of the second limiting surface 12234 away from the first limiting surface 12232. In the above solution, the structure of the limiting step is simple and convenient to set. Moreover, the limiting step in the above solution is arranged circumferentially around the second connecting section 122, so that good concentricity between the air inlet straight pipe and the cylinder body can be ensured through the cooperation between the limiting step and the air inlet port of the cylinder body. At the same time, since the included angle between the first limiting surface 12232 and the second limiting surface 12234 is an obtuse angle, that is, the second limiting surface 12234 is inclined in the horizontal direction, and in cooperation with the arc-shaped guiding portion 12235 provided at the end of the second limiting surface 12234, it is convenient to guide the air inlet port of the cylinder body to achieve limiting cooperation with the limiting step. In addition, continuing to refer to the figure Figure 3As shown, the second limiting surface 12234 is inclined, which also facilitates the solder to converge and form along the second limiting surface 12234 towards the connection between the second limiting surface 12234 and the cylinder air inlet port during the welding process, improving the welding quality and efficiency. Similarly, as a preferred implementation of Embodiment 1, refer to Figure 1 and Figure 3 As shown, the first limiting portion 1111 is a limiting inclined surface, and a guiding arc surface 1213 is provided on the inner wall of the port of the first connecting section 121.
[0044] Embodiment 2: Refer to Figure 4-6 As shown, the difference between this Embodiment 2 and the aforementioned Embodiment 1 is that the pipe body portion 11 only retains the fitting section 111 and the length of the fitting section 111 is extended compared to the fitting section 111 in Embodiment 1. However, since the axial length of the transition portion 12 in this Embodiment 2 is also extended, the axial length of the pipe body portion 11 in this Embodiment 2 is reduced compared to the pipe body portion 11 in Embodiment 1, further saving copper material.
[0045] It should be noted here that the above examples are only the preferred embodiments of the present application. The structure of the intake straight pipe in the present application is not limited to the above embodiments, and it can also adopt other more different structural schemes.
[0046] As another implementation of the present application, refer to Figure 7 As shown, the pipe body portion 11 and the transition portion 12 are integrally formed of steel. Adopting this implementation method eliminates the welding operation between the pipe body portion 11 and the transition portion 12, and also eliminates the use of copper material, further reducing the production cost.
[0047] What is not described in the present application can be achieved by adopting or referring to the existing technology.
[0048] Each embodiment in this specification is described in a progressive manner. The same or similar parts between each embodiment can be referred to each other, and the key points of each embodiment are the differences from other embodiments.
[0049] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
