Abstract
The utility model discloses a flange connector for a high temperature pipeline. The flange connector comprises a flange body, a through hole is formed at the center of the flange body, a step groove is formed in the peripheral surface of the flange body, a seal ring is covered on the step groove communicated with a temperature reducing channel port, and a temperature reducing channel is formed between the seal ring and the step groove. The flange connector for the high temperature pipeline is reasonable in structure, convenient to use and good in seal performance.
Description
Technical field
The utility model relates to a kind of high-temperature pipe flanged joint.
Background technique
The flange arrangement form is varied, and most flanges connects as flange docking in the left and right sides connects, and at the docking end face seal ring assurance sealing is set, but because the life-span of seal ring is limited, and under some hot environments, use causes sealing to reduce easily for a long time, leaks.
The model utility content
It is a kind of rational in infrastructure, easy to use that the utility model provides, and good airproof performance effectively reduces the high-temperature pipe flanged joint of the temperature of flange.
The utility model technical solution problem provides following scheme:
A kind of high-temperature pipe flanged joint, comprise flange body, it is characterized in that: the center of described flange body is provided with through hole, the outer circumference surface of described flange body is provided with stepped recesses, be stamped seal ring on the described stepped recesses, described stepped recesses is communicated with the cooling passway, forms the cooling passage between described seal ring and the stepped recesses.
Described cooling passway connects water intake, and the sidewall of described flange body is provided with the bolt hole matrix.
The utility model adopts the sidewall at flange that the cooling passage is set, and effectively reduces the probability that some hot environment lower flange seal rings lost efficacy, and structure is more firm, good airproof performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of high-temperature pipe flanged joint, comprise flange body 1, the center of described flange body 1 is provided with through hole 2, the outer circumference surface of described flange body 1 is provided with stepped recesses 3, be stamped seal ring 4 on the described stepped recesses 3, described stepped recesses 3 is communicated with cooling passway 5, forms cooling passage 6 between described seal ring 4 and the stepped recesses 3.
Described cooling passway 5 connects water intake 7, and the sidewall of described flange body 1 is provided with bolt hole matrix 8.
Claims (2)
