Description

Technical Field

[0001] This utility model relates to the field of air compressor components, and in particular to a quick-connect tee for an air compressor nitrogen generation assembly. Background Technology

[0002] An air compressor contains a nitrogen generator. Air compressors that need to produce oxygen can also produce nitrogen. Currently, most air compressors typically compress air first, then use a gas conversion machine to convert the oxygen in the air into nitrogen. The nitrogen generator consists of a nitrogen generator, conversion unit, gas pipeline, and pneumatic valve. Traditionally, nitrogen transmission within the air compressor relies solely on fixed pipelines. During compressor operation or over time, these pipelines are prone to aging, damage, and nitrogen leakage. Furthermore, the pipelines typically have tees with pneumatic valves controlling the airflow, posing a risk of high-pressure rupture within the pipeline. Fixed gas pipeline connections also require the entire nitrogen generator assembly to be removed for maintenance or replacement, which is very inconvenient. Therefore, to facilitate maintenance and repair of the nitrogen generator, it is necessary to improve the pipeline structure. Utility Model Content

[0003] To address the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide an integrated tee that can be installed in a nitrogen pipeline, allowing for quick installation and disassembly of the tee and the pneumatic valve core, facilitating maintenance, and making it more robust and durable.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] A quick-connect tee for a nitrogen generator assembly in an air compressor includes a tee and two pipes installed in the nitrogen generator assembly of the air compressor. The tee includes a double-ended pipe and a side pipe extending from the side of the double-ended pipe and communicating with it. The side pipe is obliquely arranged with the double-ended pipe. A quick-connect structure is provided between the double-ended pipe and the first and second pipes. A pneumatic valve core is provided on the side pipe.

[0006] Furthermore, the quick-assembly and disassembly structure of this utility model includes a flange 1 located at one end of pipe 1 and pipe 2 near the double-ended pipe, and flange 2 located at both ends of the double-ended pipe. The flange 1 and flange 2 are fastened together by a number of screws.

[0007] Furthermore, a sealing ring is provided between flange one and flange two in this utility model.

[0008] Furthermore, the pneumatic valve core of this utility model is provided with a pipe three, and a thread is provided at the outer end of the side pipe, and a nut is provided on the pipe three to connect to the thread.

[0009] Furthermore, in this utility model, the side tube has a 45° oblique angle on one side of the double-ended tube.

[0010] Furthermore, the tee in this utility model is integrally cast.

[0011] In summary, the advantages of this utility model over the prior art are:

[0012] This utility model features a tee valve on the nitrogen generator pipeline, which can be used to add a pneumatic valve core for gas flow control. It also allows for quick installation and removal of the tee valve and the pneumatic valve core within the nitrogen generator pipeline. In case of pipeline problems, the valve can be removed for repair or maintenance at any time. The tee valve can be removed without interfering with the nitrogen generator pipeline through its quick-installation and removal structure. The pneumatic valve core can also be removed from the tee valve by unlocking it with a nut, without interfering with the nitrogen generator pipeline. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0018] like Figures 1 to 4The present invention preferably provides a quick-connect tee for a nitrogen generator assembly of an air compressor, including a tee 1 and pipe 11 and pipe 2 12 installed in the nitrogen generator assembly of the air compressor. The tee 1 includes a double-ended pipe 2 and a side pipe 3 extending from the side of the double-ended pipe 2 and communicating with it. The side pipe 3 is obliquely arranged with the double-ended pipe 2. A quick-connect structure 4 is provided between the double-ended pipe 2 and pipe 11 and pipe 2 12. A pneumatic valve core 5 is provided on the side pipe 3. Pipeline 1 and Pipeline 2 are stainless steel pipes installed in the nitrogen assembly of the air compressor for outputting nitrogen. In this technical solution, a tee is installed in the stainless steel pipe, connected through the double-ended pipe of the tee, and can be quickly installed and disassembled through a quick-release structure, ready to be removed for repair or maintenance in case of any problems in the stainless steel pipe. The pneumatic valve core is installed on the side pipe of the tee to control the opening and closing of nitrogen entry. The flow of nitrogen is from top to bottom or from bottom to top in the double-ended pipe. The side pipe contains the movable end of the pneumatic valve core and extends to the double-ended pipe, used to block or open the double-ended pipe to allow nitrogen to flow.

[0019] The quick-installation structure 4 described in this utility model includes a flange 41 located at one end of pipe 11 and pipe 21 near the double-ended pipe 2, and flanges 42 located at both ends of the double-ended pipe 2. The flanges 41 and 42 are fastened together by a number of screws. The flanges 41 and 42 are movably fitted onto the double-ended pipe and pipes 1 and 2. When the screws are removed, the double-ended pipe can be laterally removed from pipes 1 and 2. After maintenance and repair, the double-ended pipe is laterally inserted between pipes 1 and 2, and the screws are tightened to complete the installation.

[0020] In this invention, a sealing ring 6 is provided between flange 41 and flange 42 to reduce air leakage and increase sealing performance.

[0021] The pneumatic valve core 5 of this invention is provided with a pipe 3 51, and a thread is provided at the outer end of the side pipe 3. A nut is provided on the pipe 3 51 and connected to the thread. The pneumatic valve core can be installed on the side pipe by connecting the pipe 3 to the thread through the nut and the thread. After the pneumatic valve core is installed, the valve head, as the movable end, will extend into the double-ended pipe. The movement of the valve head in the side pipe can close or open the double-ended pipe and control the air flow.

[0022] In this invention, the side tube 3 is angled at 45° on one side of the double-ended tube 2. This allows nitrogen gas to impact the valve head at an angle, reducing the pressure on the valve head.

[0023] The tee 1 described in this invention is integrally cast. This makes it more robust and less prone to damage.

[0024] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
