Description

Technical Field

[0001] The utility model relates to the technical field of rotor compressors, in particular to an integrated threaded connection liquid reservoir connection structure and a rotor compressor. Background Art

[0002] During the operation of the rotary compressor, Figure 6 As shown, the compressor performs air intake and gas-liquid separation through a liquid storage assembly, so the location where the intake pipe is connected to the shell needs to be sealed to avoid leakage of internal high-pressure gas, or leakage of high and low pressure inside the shell, to prevent leakage from causing the compressor to fail to work normally. Currently, welding is usually used for sealing, and the interior is sealed through an intake connecting pipe. The existing rotor compressor has the following technical problems: leakage may be caused by the intake connecting pipe being out of round or of unqualified size, and leakage may be caused by unqualified welding. Summary of the invention

[0003] The utility model aims to reduce the leakage rate of the intake pipe connection and provides an integrated threaded connection liquid reservoir connection structure and a rotor compressor.

[0004] The specific scheme of the utility model is: an integrated threaded connection liquid reservoir connection structure, including a liquid reservoir and a cylinder seat, an air intake pipe is provided at the lower end of the liquid reservoir, the air intake pipe is fixedly connected to the liquid reservoir, an outer wall surface of one end of the air intake pipe facing the cylinder seat is provided with an external thread, and the inner wall of the air intake hole of the cylinder seat is provided with an internal thread matching the air intake pipe.

[0005] Furthermore, the air intake pipe and the liquid reservoir are integrally formed.

[0006] Furthermore, the air inlet hole of the cylinder seat is composed of two sections, the section facing outwards is a threaded hole, and the section facing inwards is a smooth hole.

[0007] Furthermore, the diameter of the smooth hole is smaller than the diameter of the threaded hole.

[0008] The utility model also provides a rotor compressor equipped with the above-mentioned integrated threaded connection liquid storage device connection structure.

[0009] Compared with the prior art, the utility model has the following advantages: by making the liquid reservoir assembly and the intake connecting pipe as an integrated structure, and setting the tail end of the intake pipe and the cylinder intake hole in a threaded connection manner, the welding leakage rate is reduced and the leakage caused by poor internal sealing is reduced, thereby avoiding blowby, improving the efficiency of the compressor, and increasing the reliability of the compressor.

[0017] See also Figure 1-5 The present embodiment is an integrated threaded connection structure of a liquid reservoir 1, comprising a liquid reservoir 1 and a cylinder seat 4, an air intake pipe 2 is provided at the lower end of the liquid reservoir 1, the air intake pipe 2 is fixedly connected to the liquid reservoir 1, an outer wall surface of one end of the air intake pipe 2 facing the cylinder seat 4 is provided with an external thread 3, and an inner wall of an air intake hole 5 of the cylinder seat 4 is provided with an internal thread matching the air intake pipe 2.

[0018] Furthermore, the air intake pipe 2 and the liquid reservoir 1 are integrally formed.

[0019] Furthermore, the air inlet hole 5 of the cylinder seat 4 is composed of two sections, the section facing outward is a threaded hole, and the section facing inward is a smooth hole.

[0020] Furthermore, the diameter of the smooth hole is smaller than the diameter of the threaded hole.

[0021] The utility model also provides a rotor compressor equipped with the above-mentioned integrated threaded connection structure of the liquid reservoir 1. When assembling the compressor, the air inlet pipe 2 of the liquid reservoir 1 is inserted into the air inlet hole 5 of the cylinder, and then the liquid reservoir 1 is rotated several times to be threadedly connected and tightened with the cylinder seat 4; when connected in place, the liquid reservoir 1 is in a position as shown in FIG. Figure 6 The vertical state shown in the figure is then welded between the portion of the intake pipe 2 extending outside the housing and the sheath pipe of the housing. By changing the original connection mode, leakage between the intake pipe 2 and the cylinder intake hole 5 is prevented, and leakage between the intake pipe 2 and the compressor housing is also prevented.
