Description

Technical Field

[0001] The utility model relates to the technical field of pipe sealing, and more specifically, to a simple pipe sealing device. Background Art

[0002] There are several common ways to seal pipe fittings: 1. Welding sealing. Welding sealing is to fix the connection of pipes and pipe fittings together by welding to form a complete closed system. Generally, welding sealing is suitable for engineering occasions with high requirements and good sealing, such as chemical, petroleum and other industries; 2. Threaded sealing. Threaded sealing is to use threads to connect the connection of pipes and pipe fittings to form a tight closed system. Generally, threaded sealing is suitable for small-diameter pipes and low-pressure pipes; 3. Clamp sealing. Clamp sealing is to use clamp-type pipe joints to connect. The clamping ring of the clamp-type pipe joint is fixed between the pipe and the pipe fitting through a nut to form a tight closed system. Generally, clamp sealing is suitable for smaller pipes and low-pressure pipes; 4. Flange sealing. Flange sealing is to connect the connection of pipes and pipe fittings through flanges to form a tight closed system. Generally, flange sealing is suitable for high-pressure, large-diameter pipes and occasions with certain docking requirements. In addition to the above common pipe opening sealing methods, there are other sealing methods such as rubber ring sealing, clamp sealing, etc. The specific sealing method to be selected needs to be judged according to the actual situation.
