Pipeline sealing device
Technical Field
The utility model relates to the technical field of sealing devices, in particular to a pipeline sealing device.
Background
The sealing can be divided into static sealing and dynamic sealing. The static seal mainly comprises pad seal, sealant seal and direct contact seal. The static seal can be divided into medium-low pressure static seal and high pressure static seal according to the working pressure. The medium and low pressure static seal is usually sealed by a cushion made of a softer material and wider in width, and the high pressure static seal is sealed by a metal gasket made of a harder material and narrower in contact width. Dynamic seals can be divided into two basic types, rotary seals and reciprocating seals. Whether other parts which move relatively to the sealing element are contacted or not can be divided into contact type sealing and non-contact type sealing; depending on the sealing element and the contact position, these can be further divided into circumferential sealing and end face sealing, which are also referred to as mechanical seals. Centrifugal sealing and spiral sealing in dynamic sealing are sometimes called dynamic sealing because they are sealed by applying power to a medium when a machine is operated.
