Abstract
The utility model provides a flexible connection sealer for high pressure pipeline which mainly comprises a positioning sealing ring, a connecting positioning sealing ring, a connecting sleeve and a circular sealing rubber ring, wherein, the positioning sealing ring and the connecting positioning sealing ring are respectively connected with the two ends of a pipe, the connecting sleeve is sheathed on the sealing ring, and the circular sealing rubber ring is arranged in a circular cavity which is arranged on the positioning sealing ring, the connecting positioning sealing ring and the connecting sleeve. Pipeline is flexibly connected, and the circular sealing rubber ring is abutted on the connecting sleeve under the pressure of high-pressure medium. The bigger the circular sealing rubber ring receives the pressure, the better the sealing effect is. When the device is detached, the device does not need to move in the axial direction. Not being limited by the mouth of the pipe and the space, the operation is very convenient, and the quality of installation and sealing is guaranteed. Replacing flange, union and hoop, the utility model has broad application to oilfield and other high-pressure line connecting point.
Description
The utility model relates to the connection sealing of rigid pipe, and the flexibility that particularly adopt elastic sealing ring between pipe and splice sleeve, is used for high pressure line connects seal arrangement.
It is that flange, union, steel ring formula clip are first-class that high pressure line connects the most frequently used.This all is the rigid joint mode, and major defect is to move axially, and operation is trouble very.If often mount and dismount flowmeter at the point of attachment of high pressure line, because seal request is very high, and nozzle position can't move, and installing space is restricted, and just feels more that inconvenience, installation quality also are difficult to guarantee.
In view of the deficiency of above-mentioned rigid joint mode, the purpose of this utility model just is to provide a kind of high pressure line the flexible seal arrangement that connects.It need not move axially, and does not require bigger axial clearance yet, not limited by the spatial position, just can connect installation easily, and installation and airtight quality are guaranteed easily.
Above-mentioned purpose of the present utility model is realized by following technical proposals.This device is connected location seal ring, splice sleeve and ring packing cushion rubber and is formed by pipeline location seal ring, pipeline.Location seal ring and connection location seal ring and coupled ends of tubes connect and are one.Splice sleeve is enclosed within outside the seal ring of location, and its front end has internal thread and connects the outside thread of the locating seal ring connection that matches.The ring packing cushion rubber is contained in the toroidal cavity of above-mentioned three parts formation.The outer surface of O-ring seal contacts with the conical inner surface of two location seal rings, between coupled two pipe ends gap of being convenient to by O-ring seal is arranged, and generally selects 2～8 millimeters.Location seal ring and the relative opening in outer that connects the location seal ring have the gap of laying O-ring seal, are at least more than 5 millimeters.The internal circular surfaces of location seal ring and connection location seal ring is the ganoid Yuan Cone face that tilts to opening.
The thickness of ring packing cushion rubber can be 1～3 millimeter, generally selects 2 millimeters, and its inner and outer surface can be the cylndrical surface, also can be the cambered surface of outside protrusion, should have elasticity preferably.
The utility model and traditional rigid joint structure contrast, its major advantage is: simple in structure light and handy, all very convenient in all places mounting or dismounting, can guarantee to install and airtight quality.Connect if be used for the electromagnetic flowmeter joint of high pressure line, can replace original clamp band type rigid joint mode, required annex Master Cost is reduced to 100 yuan by 800 yuan every of past.In addition, connect seal arrangement, also can be widely used in the connection of the high pressure line of the drilling well in oil field and underground work etc. by the special use of this new structure design.
Accompanying drawing is that overall structure of the present utility model is partly cutd open schematic representation.Wherein 1 is pipeline location seal ring, the 2nd, and pipeline connects location seal ring, the 3rd, splice sleeve, the 4th, ring packing cushion rubber, the 5th, pipeline A, the 6th, pipeline B.
Details are as follows to embodiment of the present utility model in conjunction with the accompanying drawings.At first splice sleeve 3 is enclosed within the end of pipeline 5.Then pipeline location seal ring 1 is welded on the end of pipeline 5, again pipeline is connected location seal ring 2 and be welded on the end of pipeline 6, and make the slit between two pipes be in central position.Refill into ring packing cushion rubber 4.The outer slightly screw thread that at last internal thread of splice sleeve 3 left ends is connected location seal ring 2 with pipeline is tightened.Under the effect of high-pressure medium pressure, ring packing cushion rubber 4 outside swollen rising abut against the relative opening with 2 outers of location seal ring 1, and pressure is high more, and it is good more to seal.The radial pressure of high-pressure medium is herein mainly born by splice sleeve 3, its axial pressure mainly by the location seal ring 1 and 2 and splice sleeve 3 bear.Can guarantee the high pressure no seepage and no leakage, not have when pressure ring packing cushion rubber 4 and can inwardly shrink recovery.Also it should be noted that, though splice sleeve 3 and the location seal ring 1 between for movingly, but its gap with little for well, generally all can 0.2 millimeter 1/2nd to ring packing cushion rubber thickness, make it neither hinder the installation of splice sleeve, can prevent that again O-ring seal 4 is squeezed into location seal ring 1 and 2 and the gap of 3 of splice sleeves.
Claims (4)
