Description
Technical field
The utility model relates to the mechanical coupling of the field such as oil, chemical industry pipeline, particularly a kind of for being different from traditional internal expanding lock ring shutoff threeway in oil, the perforate of chemical pressure pipeline normal defeated pipeline on-line production, shutoff operation process.
Background technique
In oil, chemical engineering industry, oil gas normally utilizes pipeline to carry out carrying.Pipe-line can often need to carry out perforate or shutoff operation when on-line production oil gas.And existing generally traditional shutoff threeway also exists some following technological deficiencies: (1) this kind of threeway generally has several screw in the outer of flange plate, lock ring is driven to realize the locking blocked and unclamp by the screws in screw.What the accurate location of locking due to lock ring and unclamp was corresponding is the rotation number of turns controlling bolt, and the rotation number of turns of bolt is wayward, then the control of lock ring position is not very accurate, lock ring is easily caused to lock not in place, cause stifled dish do not lock and loosen, cause threeway interior media to be overflowed by screw and bring danger.(2) because multiple bolt will rotate adjustment respectively seriatim, add the whole operating time, operation is not succinct convenience very.
Summary of the invention
The utility model, for above-mentioned problems of the prior art, provides a kind of internal expanding lock ring shutoff threeway, solves complex operation in prior art, the problem that sealing effect is undesirable.
The technical solution of the utility model is as follows:
Comprise blind flange, flange, threeway standpipe, upper guard board and lower backplate, blocking is arranged on threeway riser interiors; Described blocking bottom is blockage body, and the central upper portion position of blockage body arranges cam disk, and cam disk arranges cam path, and pin is arranged in cam path through one end of lock ring bar, and the other end and the lock ring of lock ring bar touch; Flange is sealed mode flange, and the inwall of flange is provided with circular groove, and circular groove and lock ring match; Cam disk is provided with driving mechanism and positioning means.
Described driving mechanism is, the center of cam disk is provided with internal square hole, and internal square hole and blocking machine center-pole match.
Described positioning means is, blockage body is provided with positioning rod, and one end of positioning rod and one end of Regulation spring touch, and the other end of Regulation spring connects screw plug; The side of cam disk arranges positioning hole, and the other end of positioning rod embeds in positioning hole.
Described positioning hole is two, two positioning holes corresponding cam disk lock ring spreading and retracted position respectively.
Described cam path arranges four, and the radius of arc of four cam paths is equal, and four cam paths are on average arranged on cam disk.
Described blocking sidewall is provided with plug for seal circle.
Described blind flange internal surface is provided with blind flange seal ring.
Gland is provided with between described blocking and blind flange.
Described blind flange is provided with lifting bolt.
The utility model has the advantages of as follows:
The utility model avoids the shortcoming of traditional shutoff threeway.Rotating certain angle by blocking machine center-pole just can at the multiple lock ring of blocking internal drive simultaneously to external extension.Its locking, there is corresponding limit stoper unlocked position, can ensure locking, unclamp accurately putting in place of action, lock blocking accurately and reliably, there will not be the such blocking of traditional threeway to get loose phenomenon.And owing to no longer having bolt hole outside flange plate, whole threeway forms enclosed construction, so interior media can not overflow, ensure that safety in production.And just once can drive the simultaneously action of several lock ring due to blocking machine center-pole only need be rotated, make to send that to get the stifled operating time shorter, more fast and convenient safety, flange outward appearance is also more succinctly attractive in appearance.

Embodiment
By reference to the accompanying drawings the utility model is described further.
Embodiment
As Figure 1-4, comprise blind flange 1, flange 2, threeway standpipe 4, upper guard board 5-1 and lower backplate 5-2, it is inner that blocking 3 is arranged on threeway standpipe 4, is provided with gland 8 between blocking 3 and blind flange 1; Described blocking sidewall is provided with plug for seal circle 6; Blind flange internal surface is provided with blind flange seal ring 7; Described blind flange is provided with lifting bolt 9.Described blocking bottom is blockage body 3-1, the central upper portion position of blockage body arranges cam disk 3-5, cam disk is on average arranged four cam paths, the radius of arc of four cam paths is equal, pin 3-4 is arranged in cam path through one end of lock ring bar 3-3, and the other end and the lock ring 3-2 of lock ring bar touch; Flange is sealed mode flange, and the inwall of flange is provided with circular groove, and circular groove and lock ring match; Cam disk is provided with driving mechanism and positioning means.
