Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing, but is not intended to limit this reality
With novel protection scope.
In the utility model embodiment, a kind of oil-gas gathering and transferring pipeline anti-leak detection shown in Figure 1 and device for plugging,
Including upper slips 5, lower slips 1, upper slips 5 are rectangle, and lower slips 1 are U-shaped, and 1 upper surface of lower slips mounts arc-shaped plugging paste
Gasket 4 is arranged above leak stopping patch 2 for piece 2, and lower slips 1 and upper slips 5 pass through pin shaft 6 and are connected and fixed with split pin 7, on gasket 4
Shaft 8 is connected, lower part connects gland 16, and gland 16 resists the upper surface of leak stopping patch 2, and slot 13 is arranged in 1 side top of lower slips,
Compressed spring 14 is set inside slot 13, and two block keys 15 are linked together and be placed in slot 13, blocked in closing by compressed spring 14
Watts 5 and lower slips 1, block key 15 is popped up, upper lower slips 5,1 can be locked together, be tightened block key 15, open upper slips 5 greatly,
Upper lower slips 5 and 1 can be separated, pressure-sensing device and signal output line are set on one of block key 15, with outside
Pressure sensor connection.Leak stopping patch 2 is connect with gasket 4 by screw 3.Upper lower slips 5 and 1 are by from top to bottom sequentially connecting
Slot 13, bolt 9, thin nut 10, nut 11 and the washer 12 connect is fixedly connected.Lower slips 1 have different diameters, for not
Same pipe diameter selection.Further include shaft, be arranged above gland 16, is connected between shaft and upper slips 5 using trapezoidal thread
It connects, with passing movement, roller end and 16 surface joint of gland use copper gasket 4, and to reduce friction, gasket 4 passes through spiral shell
Nail 3 is fixed on gland 16, and articulation hole is arranged on gland 16, is fastened to leak stopping patch 2 by the second bolt and spherical washer
On gland 16, after the completion of soldering, gland 16 can be made to be detached from leak stopping patch 2 by unscrewing bolt.
As shown in Fig. 2, further including O-ring 17, closure is connected between leak stopping patch 2 and pipeline 18, and O-ring is placed in leak stopping
In the seal groove of 2 inner surface of patch, it is the galvanized wire or copper wire of diameter 3-4mm, seals groove width and groove depth is smaller than O-ring diameter
0.5mm.Hold out against under pressure on top surface F effect to pipeline external surface, the numerical value of F should be greater than thrust caused by leaking medium pressure with
The material selection of the sum of the active force for making O-ring reach required decrement and applying, the size of F and O-ring and leakage defect
Geometry and size are related, what O-ring was deformed under the effect of external force, by patch soldering to pipeline, complete
Leak stopping, while initial sealing is formed than pressing with the shiny surface of pipeline external surface, to achieve the purpose that anti-leak detects.It applies at scene
O-ring is fixed in the seal groove of leak stopping patch 2 by working hour, and the minimum wall thickness (MINI W.) of leak stopping patch 2 is usually not less than the minimum of slips
Wall thickness forms closed sealing cavity, the length and width of sealing cavity in seal groove to guarantee to have after soldering enough intensity
More than the 20-40mm of leakage defect actual size.
The computation model of device for plugging slips is established, in general, the outer diameter of slips is much greater compared with its thickness, and
And two side end faces of slips are free, therefore upper lower slips are in plane stress state, visual slips width direction
Stress is 0, therefore slips is simplified as the compound annulus only acted on by internal pressure, and the main stress in slips is that circumferential stretching is answered
Power.
Work on the spot process includes:
(1) aperture at conveyance conduit outer diameter and pipe leakage is measured, the leak stopping patch 2 of suitable size is chosen；
(2) leak stopping patch 2 is installed on gland 16, completes leak stopping and the integrated early-stage preparations work of leakage measuring instrumentation
Make；
(3) upper slips 5 are opened greatly, after mounting a device on pipeline, quick closedown upper slips 5；
(4) after leak stopping patch 2 being had good positioning, by the quick rotating shaft of handle, so that leak stopping patch 2 is gradually compressed pipeline and let out
Leak, leak stopping pressure are greater than pipe leakage pressure, leakage are forced to stop；
(5) necessary processing, such as decontamination, derusting, paint removal are carried out according to the requirement of welding procedure to pipe leakage region,
Then along the 2 surrounding welding of leak stopping patch, thus by 2 soldering to pipeline of leak stopping patch；
(6) after the completion of soldering, leak stopping patch is write, shaft is unscrewed, put on gland 16, then open upper slips 5, unloading is stifled
Leakage device；
(7) it reloads upper slips 5, the anti-leak pressure oscillation detection after carrying out leak stopping passes through the side of pulsed pressure wave
Formula carries out the detection whether soldering point leaks, and pulsed pressure wave is applied to whithin a period of time at soldering point, acquires at soldering point
Air pressure whether can fluctuate, thus lack it is fixed whether soldering success.
Using the present embodiment, slow, worker can work by force efficiently against blocking speed present in existing leak stopping mechanism
The defects of degree is big and less economical and deficiency, very good solution long distance pipeline do not stop production pressure sealing the problem of, while by leak stopping
Leak detecting device afterwards focuses on one, saves space, achieves preferable economic benefit.
Technical solution provided by the utility model embodiment is described in detail above, it is used herein specifically
A example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above embodiments is only applicable to help
Assistant solves the principle of the utility model embodiment；Those of ordinary skill in the art simultaneously, embodiment according to the present utility model,
