Description
Technical Field
[0001] The utility model belongs to the technical field of double vacuum structure valves, in particular to a double vacuum structure valve. Background Art
[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium (such as temperature, pressure, and flow rate, etc.). The two-way valve uses a single valve core and valve seat structure to easily control the on and off of the medium. The vacuum valve refers to a vacuum system component in a vacuum system that is used to change the direction of airflow, adjust the amount of airflow, and cut off or connect the pipeline.
[0003] Existing double vacuum valves usually need to be connected to pipelines when in use. However, when connected to pipelines, multiple bolts are usually required to be connected and fixed through flanges on the pipelines. This method is not only difficult to operate during installation and increases the operating steps of the staff, but also has low installation efficiency and cannot quickly complete the docking of pipelines. Therefore, we propose a double vacuum structure valve. Utility Model Content
[0004] The purpose of the utility model is to provide a double vacuum structure valve, which is installed by setting an installation component, specifically, after the connecting pipe and the fixed pipe are plugged in, the threaded ring is rotated counterclockwise to drive the threaded ring to move to the left side. When the moving block moves to the left side, the clamping block will push the plug block to the left side, so that the right side of the connecting pipe is tightly attached to the left side of the fixed pipe, and the installation is completed. There is no need to use multiple bolts to fix, which reduces the operation steps and improves work efficiency. It solves the problem of needing to use multiple bolts to connect and fix through the flange on the pipe, which is not easy to operate during installation and increases the operation steps of the staff.
