Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As attached Figure 1-5 The gas pipeline purging head shown has a diversion and delivery component set on the guide cylinder 1. The airflow is delivered to the guide cylinder 1 and the diversion chamber 2 through the connector 6. It is then diverted through various reinforcing pipes 3, regulating valves 4 and hoses 5, which makes it easy to deliver the airflow to different areas without the need to add or remove different connectors and pipelines, thus improving the convenience of purging. The specific structure of the component is as follows.

[0024] The diversion and conveying assembly includes a diversion chamber 2 located at the bottom of the diversion cylinder 1. Several reinforcing pipes 3, each used for diversion, are arranged on the outside of the diversion chamber 2. One end of each reinforcing pipe 3 is fitted with a regulating valve 4 via a clamp, and one end of each reinforcing pipe 3 is fitted with a flexible hose 5 via a flange.

[0025] A connector 6 is provided on one side of the surface of the guide tube 1. The connector 6 is connected to the guide tube 1. An upper ring 7 is provided on the top of the guide tube 1. Several mounting plates 8 are provided on the outer side of the upper ring 7.

[0026] A connecting cover 9 is inserted into the top of the upper ring 7. A vertical tube 10 is fixedly installed on the top of the connecting cover 9. A filter element 11 is threaded inside the vertical tube 10. The filter element 11 passes through the vertical tube 10 and the connecting cover 9 and extends into the guide cylinder 1. Several through holes 12 are opened through the outside of the diversion chamber 2. One end of each reinforcing tube 3 extends into the corresponding through hole 12 and is rotatably connected to the through hole 12. An inner liner 13 is provided inside the upper ring 7. The inner liner 13 wraps around the outside of the filter element 11.

[0027] When using the above structure, the staff will install the device at the designated location. When purging the gas pipeline, first connect one end of the connector 6 to the connecting pipe of the compressed air equipment, so that the gas discharged from the compressed air equipment enters the interior of the connector 6 through the connecting pipe. The airflow is then transported through the connector 6 to the guide cylinder 1 and the diversion chamber 2, and then diverted through various reinforcing pipes 3, regulating valves 4 and hoses 5. This makes it easy to transport the airflow to different areas without the need to add or remove different connectors and pipelines, thus improving the convenience of purging.

[0028] Meanwhile, during use, the airflow from the reinforcing pipe 3 to the hose 5 can be adjusted by the regulating valve 4, which is easy for the staff to control. When the airflow enters the guide cylinder 1, it can be filtered by the filter element 11 first, so as to prevent dust mixed in the airflow from being blown into the gas pipeline.

[0029] Unlike existing technologies, this application discloses a gas pipeline purging head. By connecting one end of the connector 6 to the connecting pipe of a compressed air device, the gas discharged from the compressed air device enters the interior of the connector 6 through the connecting pipe. The airflow is then transported through the connector 6 to the guide cylinder 1 and the diversion chamber 2, where it is diverted through various reinforcing pipes 3, regulating valves 4, and hoses 5. This facilitates the delivery of airflow to different areas without the need for additional connectors or pipes, improving the convenience of purging. During use, the airflow volume delivered from the reinforcing pipe 3 to the hose 5 can be adjusted by the regulating valve 4, making it easy for operators to control. Furthermore, when the airflow enters the guide cylinder 1, it is first filtered by the filter element 11, preventing dust mixed in with the airflow from being blown into the gas pipeline.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
