Description

TECHNICAL FIELD

[0002] The clamp is a connecting device for connecting the pipe fitting with grooves, valves and pipeline accessories. It is used for tightening the clamp between the quick connectors. Generally, the two connectors have gaskets, rubber and silicone, and tetrafluoride. However, the existing clamp for sealing the pipeline has a simple structure.

[0003] The existing patent with the authorization number CN206522568U discloses a sealing clamp for press plugging pipeline, which comprises a first clamping ring and a second clamping ring. The first clamping ring and the second clamping ring are both semicircular structures, and the first clamping ring and the second clamping ring are connected. A plurality of fixing rods are welded on the inner wall of the side of the first clamping ring and the second clamping ring close to each other. A first fixing plate and a second fixing plate are respectively arranged on the side of the first clamping ring and the second clamping ring close to each other. A plurality of buffer rods are welded on the side of the first fixing plate and the second fixing plate close to the first clamping ring and the second clamping ring. A fixing groove is formed on the side of the fixing rod close to the buffer rod. A spring is fixedly connected to the inner wall of the fixing groove, and the spring is connected to the buffer rod. Glue injection holes are formed on the two sides of the first clamping ring and the second clamping ring close to each other. The device can be used for pipelines with different diameters, effectively improving the use quality of the clamp device. After analyzing the clamp, it can be found that when the press plugging seal is performed, only a small number of glue injection holes are provided, and the space between the inner side of the glue injection hole and the pipeline lacks effective leakage prevention structure, which can easily cause the sealing glue to leak outward. Moreover, when the glue injection is performed, a large amount of glue needs to be injected to seal the leakage points of different sizes, which can easily cause the waste of sealing glue.
