Abstract
The utility model relates to a technology tee bend is pressed in oil gas pipeline area, including tee bend backplate, tee bend takeover, tee bend main part, flange and stopper handle, the last port of tee bend main part is equipped with the head admittedly, has a keyway in tee bend main part outer fringe axial system, and the axial round pin is equipped with a locking key in this keyway, plane inner edge system has an annular on the flange, and coaxial arrangement has the sealed pad in rim of the mouth in this annular, should seal and install the sealing washer between pad and the tee bend main part. This shutoff three -way flange is connected with tee bend main part thread engagement to it is radially fixed to adopt the locking key to go on, and the rim of the mouth is sealed fills up sealedly, and the back is accomplished in the shutoff construction, stays burying on the pipeline and can not cover the blind plate after the ground tee bend is sealed through the welding head, does not keep the bolt, as staying the pipe fitting on the pipeline, accords with the requirement that the long distance pipeline buried the ground permanence more, has reduced leakage hidden danger, and the effect of preventing burglary is very good, has effectively avoided the potential safety hazard.
Description
Technical field
The utility model belongs to oil gas transmission field, relates to the threeway of a kind of oil and gas pipes band compression technology.
Background technique
Shutoff threeway is the technique threeway of a kind of indispensability implementing press and open holes shutoff operation on oil and gas pipes.Threeway main body, shutoff backplate, plug handle, blind plate, bolt, distinguish snap ring is included in traditional a set of shutoff threeway, threeway main body radial direction is packed on shutoff backplate, in threeway main body, coaxial positioning is packaged with plug handle, mount cover blind plate in threeway main body upper end, it is fastening that this blind plate carries out encapsulation by bolt.As publication (title: a kind of shutoff threeway, publication number CN201764181U) described in, this shutoff threeway comprises blind flange, has the fluting flange of operation path, the threeway plug handle be arranged in described operation path, threeway backplate and the snap ring mechanism that is arranged on described fluting flange; One end of described fluting flange is fixedly connected with described threeway backplate, and the other end and described blind flange removably connect; Described threeway plug handle outer surface is provided with plug handle seal groove and snap ring locking groove, is provided with plug handle seal ring in described plug handle seal groove.
The shutoff threeway of above-mentioned public technology file, after installing, leaves blind plate and outer connecting bolt, impacts follow-up corrosion prevention operation in outside.And this mode of structure, opens blind plate to robber's unthread bolts and steals oil gas and provide condition, and therefore anti-theft effect is poor; Meanwhile, stolen result also produces the leakage of pipeline, and potential safety hazard is comparatively large, does not meet the buried permanent requirement of long distance pipeline.
By retrieval, not yet find the patent document identical with the present patent application.
Model utility content
The purpose of this utility model is the deficiency overcoming original technology, provide that a kind of design science is ingenious, good anti-theft effect, oil and gas pipes band compression technology threeway with low cost.
The purpose of this utility model is achieved in that
The threeway of a kind of oil and gas pipes band compression technology, comprise threeway backplate, t-joint, threeway main body, flange and plug handle, threeway backplate radial through weld the t-joint that is fixedly mounted with and threeway main body coaxial welding is fixedly mounted with, be communicated with t-joint and threeway backplate in threeway main body, in threeway main body, coaxial radial location is packaged with plug handle, in threeway main body outward by thread engagement mode mounting flange, it is characterized in that: the upper end-hole of described threeway main body is fixed with end socket, axially a keyway is shaped with in threeway main body outer rim, in this keyway, axial pin is equipped with a locking key, this locking key radial location is fixedly mounted with flange, on flange, plane inner edge is shaped with an annular groove, is coaxially installed with rim of the mouth sealing gasket in this annular groove, is provided with seal ring between this rim of the mouth sealing gasket and threeway main body.
And what described end socket adopted is hemisphere shape.
And the upper plane of described rim of the mouth sealing gasket protrudes plane on flange.
And described threeway inner major diameter adopts packing to position to the plug handle of positioning package.
Advantage of the present utility model and good effect are:
1, the flange of this shutoff threeway and threeway main body screw are connected with a joggle, and adopt locking key carry out radial direction fix, the sealing of rim of the mouth sealing gasket, after plugging construction completes, stays buried threeway on pipeline by can not lid blind plate after the sealing of welding end socket, do not stay bolt, as the pipe fitting stayed on pipeline, more meet the buried permanent requirement of long distance pipeline, decrease leakage hidden danger, anti-theft effect is very good, effectively prevent potential safety hazard.。
2, can by demounting flange after this shutoff threeway installing stopper handle with pressure, at the welding end socket suitable for reading of threeway main body, can not study in France after welding orchid and blind plate, be convenient to the corrosion prevention operation of postorder more.
3, the flange of this shutoff threeway is reusable after removal, and can cut the finished product expense of blind plate, bolt, flange, greatly reduces cost, and design science is reasonable, is skillfully constructed.
Accompanying drawing explanation
Fig. 1 is form structure schematic diagram of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.
The threeway of a kind of oil and gas pipes band compression technology, comprise threeway backplate 6, t-joint 5, threeway main body 4, flange 3 and plug handle 9, threeway backplate radial through weld the t-joint that is fixedly mounted with and threeway main body coaxial welding is fixedly mounted with, be communicated with t-joint and threeway backplate in threeway main body, in threeway main body, coaxial radial location is packaged with plug handle, in threeway main body outward by thread engagement mode mounting flange.
Innovative point of the present utility model is:
The upper end-hole of 1, threeway main body adopts welding manner to be welded with end socket 1, and what this end socket adopted in the present embodiment accompanying drawing is hemisphere shape, also can adopt other shapes.Threeway main body adopts welding end socket mode, can make to close with the external world in threeway main body, avoids leaking and stolen.
2, be axially shaped with a keyway in threeway main body outer rim, in this keyway, axial pin is equipped with a locking key 10, and this locking key radial location can be fixedly mounted with flange; On flange, plane inner edge is shaped with an annular groove, is coaxially installed with rim of the mouth sealing gasket 2 in this annular groove, is provided with seal ring 7 between sealing pad and threeway main body; The upper plane of rim of the mouth sealing gasket protrudes plane on flange, to realize the seam location fit with valve.
3, threeway inner major diameter adopts packing 8 to position to the plug handle of positioning package.
Using method of the present utility model is:
After plugging holes operation completes, installing stopper handle with pressure, after being blocked by flange inner spout, is rotated counterclockwise flange, flange can be laid down, and then at upper orifice place welding end socket, completes the sealing work of shutoff threeway.Locking key is control flange location, and namely rim of the mouth sealing gasket plays the effect of location, flange rim of the mouth, plays again the seal action that O RunddichtringO coordinates with threeway flange.
