Abstract
The invention discloses a flange type connecting device which comprises a connector body, a hexagon head, a flaring type connector body and an O-shaped sealing ring. The flange type connecting device is characterized in that a groove is formed in the conical face of the end socket of the flaring type connector body, the O-shaped sealing ring is arranged in the groove, the connector body is sealed by adopting a flange structure, and expansion tensile stress sealing is achieved between the conical face of the flaring type connector body and the O-shaped sealing ring making contact with a conical face matched with the conical face of the flaring type connector body. A hexagon flange structure is adopted by the hexagon head. Outer connecting threads are arranged on the connector body, and a through hole is formed in the middle of the connector body. The flange type connecting device is based on a normally-used flaring type transition connector and aims to solve the current problem of leakage of low pressure pipelines of an engine, the O-shaped sealing ring is used, and the hexagon flange structure is adopted. Leakage can be prevented effectively, the sealing performance of the pipelines can be improved, and manufacturing and machining cost can be lowered. Through the adoption of the hexagon flange structure, the pressure bearing area of a sealing face is enlarged, parts are protected against damage, the metal and metal combined sealing is replaced by the sealing of the rubber ring, and the flange type connecting device is easy to manufacture, convenient to use, good in sealing performance, multiple in sealing layer and high in reliability.
Description
Technical field
The invention belongs to a kind of flange-type connection set of diesel low-voltage line seal.
Background technique
Between commercially available or existing flared type transit joint and joint, seal form adopts metal covering and metal covering sealing, has poorly sealed hidden danger.Use common flared fitting sealing surface requirement machining accuracy high, process roughness 1.6 left and right and control the form and position tolerances such as its planeness, perpendicularity, parallelism, coaxality, and with heat treatment process, softening surface increases sealing.Adopt firmly+hard sealing means of general flared fitting sealing surface, sealing surface is easy to wear, causes leakage.General transit joint is tightened position and is adopted hexagonal structure, and pressure-bearing surface is little, and easily contacts with part attachment face in assembly process, injuring part surface.
Summary of the invention
The object of the present invention is to provide and a kind ofly on the flared fitting conical surface, process a groove for mounting O-shaped seal ring, during two joint sealings contacts, utilize between it pressure that O RunddichtringO is expanded and form seal action.Hexagon head adopts hexagonal flange structure, increases pressure-bearing surface, and protection part is injury-free, and this transit joint is simple in structure; easy to manufacture, easy to install, in the flared fitting conical surface mounting O-shaped rubber seal of transit joint; good seal performance, multi-layer sealing structure, reliability is high.
Technical solution of the present invention is such, a kind of flange-type connection set, comprise fittings body, hexagon head, flaring type joint body, O RunddichtringO, it is characterized in that being processed with groove on the conical surface of flaring type joint body (3) termination, O-ring seals (4) is housed on groove, and fittings body (1) adopts flange arrangement sealing.
Flaring type joint body (3) bevel is fluted, and O RunddichtringO (4) is housed on groove.
Hexagon head (2) adopts hexagonal flange structure.
Fittings body (1) has outer connecting screw, intermediate throughholes.
On flaring type joint body (3) external diameter, have groove mounting O-shaped seal ring (4).
Advantage of the present invention is: utilize hexagonal flange structure, strengthen pressure-bearing surface, alleviate transit joint weight, processing is simple, by the contact between the flared fitting conical surface and the conical surface, RUBBER O RunddichtringO is expanded and play seal action, replace hard+hard sealing means general in flared fitting.Easy to manufacture, easy to install, cost is low, good seal performance, and resistance to pressure is good, and parallelism, perpendicularity, coaxality are good.Easy to manufacture, easy to install, cost is low, good seal performance, and resistance to pressure is good, and parallelism, perpendicularity are good, and coaxality is good.
