Abstract
The utility model relates to a pipeline sealing connection device, which is characterized in that both ends of a pipe 1 are provided with connection clamp heads 2. A connection flange 3 is sheathed on the outer edge of the connection clamp head 2 and is connected and fixed by a bolt 4, the sealing element between the two pipes is a curved surface sealing ring 5, and the flange can connect and fix the two pipes. The utility model overcomes the disadvantages of existing pipeline sealing connection devices with slip connection fixing and keystone ring sealing, and has the advantages of small size, light weight, good sealing performance, convenient operation, low cost and antitheft performance. The utility model is suitable for connecting the pipes of transporting high temperature and pressure liquid and gas.
Description
The utility model proposes and be applied to the line seal connection set that mechanical field is used for the pipeline connection.
Existing pipeline connecting device has following several:
1, pipe collar screwed connection, having shortcoming is the dismounting inconvenience, is not suitable for the connection of big caliber pipeline, and sealing is poor, is not suitable for high temperature, the use of high pressure occasion.
2, the Flange Plane sealing gasket connects, and exists shortcoming to be, be subjected to the heat-resisting withstand voltage condition restriction of gasket material, and sealing is poor, and the seal operation difficulty.
3, the slips cambridge ring connects, and is suitable for carrying high temperature and high pressure gas or liquid, also is applicable to the connection of heavy caliber pipeline, but exist shortcoming to be, slips heaviness, horizontal firm operation inconvenience, the installation requirement pipeline is straight and concentric, inner cambridge ring sealing is poor, and natural contraposition is poor, thereby, the fitting operation difficulty is big, it is improper to install, and causes the joint rupture and leakage easily, the phenomenon that slips comes off.
The purpose of this utility model is, provides a kind of fitting operation easy, and the line seal connection set of good airproof performance.
Realize that scheme of the present utility model is, the pipe joint in flat oblique outcurve garden in the two ends of pipe are provided with, and use the flange that mates with the bent garden of pipe joint outer rim face to be connected and fixed another pipe flange by bolt and pipeline parallel direction with recessed bent garden end face.The curved surface seal ring is installed in the middle of the flat incline plane in two pipe joints.
The seal connection that adopts the utility model scheme to make.Because seal ring is curved-surface structure, contact with the pipe joint flat incline plane is that loop wire contacts, and pressure is big, and sealing plane is not parallel also can reach the better seal effect.Because flange has the concave curved surface that is complementary with pipe joint, make it have self-aligning again,, also have under the situation of decentraction effect is installed preferably even not parallel in two tube's axis.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is the utility model structure sectional view.
Fig. 2 connects the dop sectional view for the utility model pipe.
Fig. 3 is the utility model curved surface seal ring sectional view.
Fig. 4 is the utility model flange sectional view.
Among Fig. 1, (1) is pipe, be connected with connection dop (2) respectively at pipe (1) two ends, adpting flange (3) is enclosed within on connection dop (2) outer rim of pipe (1), between two pipes that needs are fixed curved surface seal ring (5) is installed, the adpting flange (2) that is enclosed within on two pipes connects locking by firm bolt (4).
Among Fig. 2, (1) is pipe, is provided with at an end of pipe to connect dop (2), seals inclined-plane (2a) and outer fastening curved surface (2b) in being provided with on connecting the outer fastening curved surface (2) of dop.
Among Fig. 3, (5) are the curved surface seal ring, are the curved wall (5a) of curved surface in the outer rim of encircling, and the ring lumen orifice is ring cavity (5b).
Among Fig. 4, (3) are adpting flange, and adpting flange (3) is provided with and is connected the fastening curved surface (3a) that dop (2b) radian matches, and are provided with several fastening screw keyholes (3b) with axis parallel around it.
Embodiment's explanation:
Make oil field high-temperature steam delivery pipe connection set with technical solutions of the utility model.
The seamless steel pipe of intercepting certain-length is pipe (1), makes with same material to connect dop (2) again, and will connect dop (2) and be welded on pipe (1) two ends, and outer rim turning is processed.Make adpting flange (3) with metal, be enclosed within on the pipe (1), two tube heads of as above structure are relative, install curved surface seal ring (5) betwixt, connect two flanges also firm by firm bolt (4), the curved wall (5a) of curved surface seal ring (5) is contacted with interior sealing inclined-plane (2a) on being connected dop (2), play the effect of sealing.
This connection set through using proof, has and installs easily, the contraposition good seal performance, and it is low that labor intensity is installed, and do not have the hidden danger of leakage, the characteristics of safety.
Claims (4)
1. line seal connection set, the isostructural pipe of two-phase is relative, by the flange bolton, two pipes are connected, it is characterized in that, be provided with connection dop (2) at pipe (1) two ends, adpting flange (3) is enclosed within pipe (1) and connects dop (2) outer rim, two pipes with bolt (4) connection and fastening, are equipped with curved surface seal ring (5) relatively between two pipe clamp heads.
2. connection set according to claim 1 is characterized in that pipe connects dop (2) and is provided with interior sealing inclined-plane (2a) and outer fastening curved surface (2b).
3. connection set according to claim 1 is characterized in that, has curved wall (5a) and ring cavity (5b) on the curved surface seal ring (5).
