Description
Technical field
The present invention relates to a kind of method for blocking, in particular, the present invention relates to a kind of method that temporary plugging gas pipe line FlexbleJoint leaks.
Background technique
At present, most of iron and steel enterprises in industrial production, under PRODUCTION STATUS, often there is suddenly the leakage problem of gas pipe line FlexbleJoint, if do not processed when leak source is very little, As time goes on, leak source will be increasing, so that replacing of being forced to stop production the FlexbleJoint of leakage occurs or carries out repair welding to becoming large leak source.
But stop production in process on the impact of manufacturing schedule, general enterprises does not do timely process to less leak source, just arranges warning region and monitors in real time leak source, treat that leak source to develop into when must stop production just directly to stop production and process.
Those skilled in the art are known, such processing mode, although temporarily can keep the normal state of the production order, there is following shortcoming:
(1) leakage problem (even if leak source is very little) of not process has in time left greatly potential safety hazard;
(2) become large leak source gradually and can increase accident probability and equipment stop production to overhaul rate;
(3) the leakage process of being forced to stop production, extends the off-time, affects manufacturing schedule.
Summary of the invention
Object of the present invention is exactly the shortcoming overcoming prior art, and provides a kind of method that temporary plugging gas pipe line FlexbleJoint leaks for this reason.The enforcement of this inventive method, can process the little leak source that FlexbleJoint occurs in time, thus the potential safety hazard effectively avoiding gas leakage problem to bring and production loss.
The method that temporary plugging gas pipe line FlexbleJoint of the present invention leaks, comprises the following steps:
(1) outside dimension occurring the FlexbleJoint of leak source is measured;
(2) the bow brick that its inwall radian is coincident with described FlexbleJoint external diameter ripple radian is made;
(3) on the pull bar sidewall of leak source side, its plane orthogonal is welded in the stainless steel strut of this pull bar sidewall at FlexbleJoint;
(4) on described stainless steel strut, with front and back, the symmetrical and mode evenly arranged in left and right is processed with several borings and in described boring, welds the nut communicated with it;
(5) long full silk screw rod is installed in described nut;

Embodiment
In order to make technological scheme of the present invention more easily be understood, below in conjunction with drawings and Examples, the method that temporary plugging gas pipe line FlexbleJoint leaks is described in detail.
There is the situation of leak source in Fig. 1 FlexbleJoint shown for gas pipe line.
As seen from Figure 1, the two ends of FlexbleJoint 1 are arranged through the pull bar sidewall 2 that pull bar 3 is connected respectively, and in the illustrated embodiment, the leak source 8 on described FlexbleJoint 1 appears at the ripple top near one end pull bar sidewall 2.
Fig. 2 shows the side structure of the bow brick of leak source on shutoff FlexbleJoint.
As seen from Figure 2, the side view of bow brick 5 has certain thickness circular arc, and this circular arc interior is the trough radius of FlexbleJoint 1 ripple through R1, and the external diameter R2 of this circular arc is the radius of FlexbleJoint 1 crest.
Fig. 3 shows the situation of leak source on device shutoff FlexbleJoint that the present invention utilizes temporary plugging gas pipe line FlexbleJoint to leak.
As seen from Figure 3, the waviness width of described FlexbleJoint 1 is M, and the crest of described FlexbleJoint 1 ripple is N to the distance of trough.
With reference to Fig. 1, Fig. 2, Fig. 3, the method for the device shutoff leak source that the present invention utilizes temporary plugging gas pipe line FlexbleJoint to leak, comprises the following steps:
(1) outside dimension occurring the FlexbleJoint 1 of leak source 8 is measured, this outside dimension comprises the crest of ripple and trough radius, waviness width M and the crest distance N to trough, in order to ensure the construction safety of survey crew, require that survey crew dresses air respiratorresuscitator, if high-lift operation, must fasten seat belts;
(2) according to the outside dimension data of measured described FlexbleJoint 1 and the position of described leak source 8 on it, with the steel plate setting-out blanking of thickness 10mm, the bow brick 5 that its inwall radian is coincident with described FlexbleJoint 1 external diameter ripple radian is made:
If leak source 8 is positioned at ripple top, then the width of described bow brick 5 is a waviness width;
If leak source 8 is positioned at ripple bottom, then the width of described bow brick 5 is two waviness widths;
(3) on the pull bar sidewall 2 of leak source 8 side, weld the thick and stainless steel strut 4 be positioned at above described leak source 8 of 20mm at described FlexbleJoint 1, the plane orthogonal of described stainless steel strut 4 is in described pull bar sidewall 2 (being parallel to described pull bar 3);
(4) position corresponding to described leak source 8 on described stainless steel strut 4 arranges 4 borings by the mode that all around is symmetrical respectively and in described boring, welds the nut 6 communicated with it respectively;
(5) the long full silk screw rod 7 of difference precession in described nut 6, makes it can apply a stretch pressure to described bow brick 5;
(6) between the inwall and the external diameter of described FlexbleJoint 1 of described bow brick 5, fill the asbestos cloth 10 being stained with bath of glass, require that the filling thickness of described asbestos cloth 10 is not less than 20mm.
(7) screw the full silk screw rod 7 of described length, to make described bow brick 5 be pressed on the leak source 8 of described FlexbleJoint 1, complete the interim leak stopping of non-stopping production;
(8) leak case of leak source 8 described in gas alarm instrument Real-Time Monitoring is utilized, to determine maintenance down at any time depending on leakage situation, hidden danger of stopping a leak.
In the method for aforementioned shutoff leak source, if described leak source 8 is in the ripple bottom of described FlexbleJoint 1, can the asbestos cloth 10 being stained with bath of glass be filled up the whole wave bottom of described leak source 8 position in advance and compress compacting, again by the requirement of abovementioned steps (6), between the inwall and the external diameter of described FlexbleJoint 1 of described bow brick 5, fill the asbestos cloth 10 being stained with bath of glass.
In the method for aforementioned shutoff leak source, specification, the quantity of described nut 8 and long full silk screw rod 7 can be selected in the following manner:
Generally, the specification of described nut 8 and long full silk screw rod 7 is M22, and quantity is 4;
If stretch pressure is not enough, then the specification of described nut 8 and long full silk screw rod 7 can be selected in M24 or M26, or the quantity of described nut 6 and long full silk screw rod 7 is increased to 6 or 8 respectively.
In the method for aforementioned shutoff leak source, if produce bending by screwing described length full silk screw rod 7 to described bow brick 5 stainless steel strut 4 applied described in stretch pressure season, then can weld a diagonal brace 9 between described stainless steel strut 4 and described pull bar sidewall 2, thus improve the intensity of stainless steel strut 4.
In order to ensure best plugging effect, when the leak source 8 described in shutoff, the base of described bow brick 5 should be made not touch the ripple trough of described FlexbleJoint 1, and the thickness a when asbestos cloth 10 of filling between the inwall of described bow brick 5 and the external diameter of described FlexbleJoint 1 is compacted should be not less than 10mm.
Above with reference to drawings and Examples, schematically describe technological scheme of the present invention, this description is not restricted.Those of ordinary skill in the art will be understood that in actual applications, and in the inventive method, some change likely occurs some step, and other staff also may make similar Design under its enlightenment.Special needs to be pointed out is: only otherwise depart from design aim of the present invention, all apparent changes or similar Design, be all included within protection scope of the present invention.
