Description

Technical Field

[0001] The utility model relates to the technical field of gas source pipe joints, in particular to a gas source pipe joint device. Background Art

[0002] The air source pipe, also known as the pneumatic pipeline or pneumatic signal pipeline, is a pipeline system used to transport compressed air or other gases. It is usually composed of clean compressed air that is dry, oil-free, and free of mechanical debris, and sometimes nitrogen is used as a medium. The working pressure of the air source pipeline is generally between 0.7 and 0.8 MPa. These pipeline systems are widely used in many fields such as industry, medical care, and energy, such as pneumatic tools, pneumatic control systems, and air supply for medical equipment. The material of the air source pipeline is usually stainless steel seamless steel pipe to ensure its durability and safety. In addition, the connection of the air source pipeline is usually carried out through steel pipes or copper pipes to ensure the stability and efficiency of gas transportation.

[0003] However, the joints used in the connection of gas source pipes are all sleeved on the gas source pipes, and the diameter of the joints is larger than the gas source pipes. In order to reduce the space occupied by the gas source pipes, the gas source pipes are often changed from separate pipes to densely arranged pipes. However, the thicker joints occupy a larger space when the gas source pipes are connected. Therefore, under the premise of ensuring that the gas source pipes are closely arranged and routed, the position of the gas source pipe joints requires the staff to bend and stagger the gas source pipes to complete the connection. This method is not only time-consuming and labor-intensive, but also reduces work efficiency, is not beautiful, and occupies a relatively large space. Therefore, we propose a new gas source pipe joint device. Utility Model Content
