Description
Technical field
The invention belongs to pipe technology fields, more particularly to a kind of closure threeway anti-rotation device.
Background technique
During oil, feed channel block, blocking threeway is core equipment, but after blocking completion, blocks threeway
It can stay on pipeline, the stifled limit setting that rotates in a circumferential direction not filled in due to blocking threeway, so may during pipeline performance
There is backplate and fills in stifled rotation, it is more difficult to later period pipe-line maintenance, it is interior to detect wiper ball when leading to ball, even stifled ball, some situations
Under also need to re-start plugging construction.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of closure threeway anti-rotation device, energy after closure
Enough limitations block that threeway plug is stifled and saddle shaped plate rotation, can be effectively solved difficult in maintenance caused by blocking threeway rotation and detection
When there is the problems such as abnormal.
The technical solution adopted by the present invention is as follows：
A kind of closure threeway anti-rotation device, including a position-arresting disk, two limited blocks；Two limited blocks are bolted on
On the blank flange for blocking threeway；The plug that the position-arresting disk is bolted on closure threeway blocks；Saddle shaped plate passes through spiral shell
Bolt is fixed on the stifled another side of plug.
Further, screw hole is opened on blocking threeway blank flange, bolt passes through screw hole for blank flange and limited block phase
Connect, the screw hole opened up is connected in straight line and passes through the center of circle, right on blank flange after being installed with two limited blocks of guarantee
Claim and same diametrically.
Further, two limited blocks are symmetrical arranged on blank flange in the center of circle, the telecentricity of two limited blocks
The distance between end is less than the diameter dimension of position-arresting disk.
Further, limiting slot and screw hole there are two being set on the position-arresting disk；The connecting hole that position-arresting disk and plug block up utilizes
The stifled connecting hole of original plug, does not influence plug and blocks up original function, be the closure during under complete plug it is stifled after, seal blank flange
Position-arresting disk plug is bolt-connected to before to block.
Further, two limiting slots are symmetrical arranged, and are connected across the position-arresting disk center of circle；The depth of limiting slot
The depth dimensions of size and limited block are consistent, and the width of limiting slot is greater than the width 3-5mm of limited block, specific width according to
The model of threeway is blocked to determine, the closure threeway width of different model is different.
Blank flange is covered after the completion of blocking, while limited block is fallen into the limiting slot of position-arresting disk, realization limitation is filled in stifled
Axial-rotation limits the rotation of saddle shaped plate.
Beneficial effects of the present invention：
In the case where no influence blocks the original function of threeway, limit function is realized with the easiest way, effectively
It limits and blocks the stifled rotation of threeway plug, and then avoid saddle shaped plate and rotate issuable risk, be convenient for pipe-line maintenance, significantly
It is the phenomenon that reducing maintenance difficulty, wiper ball, even stifled ball are avoided when detecting logical ball inside, easy to operate, it uses manpower and material resources sparingly.
