Problems solved by technology

The above sealing structures all focus on how to seal better or prolong the life of the seal; however, even the best seals also have a service life
Once the leakage of one seal leads to shutdown and maintenance, the pressure of the whole system must be released. Therefore, the seals of the whole system will receive different damages and have to be replaced, resulting in huge waste
Shutdown maintenance not only delays the production cycle, but also causes a lot of waste in logistics, and the handling of related materials is not a small cost

Embodiment 1

[0053] like figure 1 As shown, the pipe connector of the Kalan method is composed of left and right symmetrical pipe connectors 7, which are clamped together by ferrules 8, and the bolts 9 or nuts 10 are tightened, so that the distance between the two ferrules 8 is shortened, and the two pipes are connected. The parts 7 are squeezed by the ferrule 8 and come close to each other, and clamp the sealing ring of the pipe connector installed between the pipe connecting parts 7; it plays a role of sealing. The pipe connector sealing ring can also be as Figure 4 As shown, it is used in pipe connectors with flange connection. The pipe connector 7 has a flange, and by tightening the bolts 9 or nuts 10, the distance between the two pipe connectors 7 is shortened, and the pipe connector sealing ring installed between the pipe connectors 7 is clamped; to the sealing effect.

[0054] like figure 2 As shown, the sealing ring of the pipe connector includes a two-part structure of the l...

Embodiment 2

[0062] The glue injection part 3, the connecting part 2 and the lip part 1 in the embodiment 1 are provided integrally; as Figure 16 In this embodiment shown, several examples in which the glue injection part 3 , the connecting part 2 and the lip part 1 are provided separately are listed; those skilled in the art can also make changes and combinations. Figure 16 The sealing ring of the middle pipe connector is divided into three rings: lip part 1, connecting part 2 and glue injection part 3, and the three rings are nested together in sequence; the connection part 2 makes the glue injection part 3 of the outer ring and the lip part of the inner ring The distance between 1 remains fixed; the thickness of the ring of the connecting part 2 is smaller than the thickness of the ring of the lip 1 and the injection part 3, and a cavity is formed on both sides of the connecting part 2 as a plugging container for the plugging glue. slot. can also be like Figure 17 As shown, the con...

Embodiment 3

[0065] The high-pressure self-tightening flange has been improved, and a leak-stopping ring is added. The leak-stopping ring is a T-shaped ring or an I-shaped ring, and the socket on one side is provided with a glue injection hole. When in use, a certain cavity is formed between the plugging ring and the socket, and a glue injection hole is provided at the position corresponding to the cavity. When leakage occurs, a certain gap is formed between the leak plugging ring and the socket directly through the glue injection hole. The cavity is treated with glue injection to form an annular sealing rubber ring, which plays the role of plugging. Glue to achieve the effect of sealing on both sides.

[0066] There is at least one glue injection hole on the plugging ring, and the glue injection hole is connected with the glue injection valve through the gap between two kalans, or a through hole is provided on the kalan, communicated with the glue injection hole, and connected with the gl...

Abstract

The invention discloses a pipe connector sealing ring. The pipe connector sealing ring comprises an annular rib part extending in the radial direction and an annular lip part extending in the axial direction; the two sides of the rib part are each provided with an annular sealing groove; the sealing grooves on the two sides are mutually communicated; a plurality of glue injecting holes are formedin the circumferential direction of the rib part; the sealing grooves are communicated with the glue injecting holes; and the outer ends of the glue injecting holes are provided with a glue injector connector. According to the pipe connector sealing ring, by arranging a reserved standby sealing cavity and the glue injecting connector; after a sealing piece leaks, sealing glue is injected in from the glue injecting connector so that the standby sealing cavity can be filled with the sealing glue, and secondary sealing on a pipe connector is achieved. Due to secondary sealing, system shutdown overhauling caused by leaking of a certain sealing piece is avoided, the cost for replacing the system sealing piece is reduced, and besides, the extra high cost generated due to system shutdown overhauling is saved; and very high economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of pressure pipeline equipment, in particular to a pipeline connector sealing ring. Background technique [0002] A pipeline system often contains dozens or even hundreds of pipeline connectors, and if any pipeline connector fails to seal and leaks, the pipeline system is a work with injuries. If the flow of the pipeline is toxic, harmful fluid, or flammable or explosive fluid, any failure of the seal of the pipeline connector will force the entire pipeline system to be shut down for maintenance, otherwise it will easily lead to major accidents. [0003] At present, pipe connectors, such as flanges and collars, all adopt a gasket or sealing ring structure. Common gaskets, such as corrugated gaskets, winding gaskets, asbestos gaskets, rubber gaskets, etc., and even soft metal gaskets, such as copper gaskets; common sealing rings, such as: convex lens rings, octagonal rings, self-tightening seals Ring etc. The above-...
