Abstract
The invention provides a method for plugging or repairing a pressurized fluid pipe. The method includes: connecting a ball valve to one end of a sleeve with two end openings to form a ball valve unit which opens or closes the end of the sleeve by opening or closing the ball valve; opening the ball valve of the ball valve unit, sleeving the outside of the pressurized fluid pipe with the ball valve unit, allowing branch fluid pipes to be branched from a master fluid pipe of the pressurized fluid pipe which is filled with fluid; welding the other end of the sleeve to the outer wall of the master fluid pipe, and closing the ball valve of the ball valve unit. The pressurized fluid pipe can be plugged or damaged parts of the pressurized fluid pipe can be repaired by the method without affecting normal operation of pipelines, and accordingly unnecessary economic loss to factories caused by production halt for pipe maintenance is avoided.

Describe below with reference to accompanying drawings embodiments of the invention in detail.
Fig. 1 shows the schematic representation according to the method for the shutoff fluid hose with pressure of one exemplary embodiment of the present invention.Fig. 2 shows the schematic representation according to the method for the reparation fluid hose with pressure of another exemplary embodiment of the present invention.
As shown in Figure 1, in the once industrial water pipe maintenance construction of certain cold rolling mill, four branching pipes (DN50 pipe) of place industry water pipe (water main is DN200) need to be cut away then shutoff.Can not affect cold rolling mill and normally produce in whole maintenance construction, water main can not be cut off the water.After branching pipe is cut away, there are current with pressure to flow out always, can't directly weld with electric welding.
Therefore, first DN65 ball valve of a connection at sleeve pipe (for example, steel pipe DN65, long 200mm) (for example, the two ball valve adopts with steel pipe and is threaded) is to form a ball valve unit.Then, open the DN65 ball valve of ball valve unit, and the ball valve unit is sleeved on the branching pipe of DN50.Here, if the length of branching pipe is not less than 200mm, then need be cut to length less than 200mm, so that in branching pipe can be sleeved on fully by the ball valve unit.Next, with other end and the water main welding of DN65 steel pipe, shown in the welding part among Fig. 1; Welded and rear ball valve has been closed, so just reached the effect of branching pipe shutoff.This exemplary embodiment can make the current of branching pipe normally flow out by the ball valve unit is set, thereby can weld in situation not with pressure the welding part, and then has improved welding quality.In this exemplary embodiment, sleeve pipe is identical with the ball valve diameter, so that the two directly connects by screw thread.The diameter of sleeve pipe is not more than the diameter of water main, thereby can finish welding.Gap between the internal diameter of sleeve pipe and the external diameter of branching pipe preferably is set to 5～20mm.
Fig. 2 shows the schematic representation according to the method for the reparation fluid hose with pressure of another exemplary embodiment of the present invention.
As shown in Figure 2, when the little slight crack repair water main (branching pipe also can) by the method for reparation of the present invention fluid hose with pressure on, hole etc., directly with ball valve (for example, the DN65 ball valve) sleeve pipe that is connected to both ends open (for example, steel pipe DN65, long 200mm) on the end, to form the ball valve unit, a described end of sleeve pipe can be realized by the opening and closing of ball valve opening and closing in this ball valve unit; Open the ball valve of ball valve unit, and the other end of the sleeve pipe of ball valve unit is covered and is welded on the outer wall at place to be repaired of water main; Close the ball valve of ball valve unit.Here, the projector distance of slight crack should be not more than the diameter of water main, and the maximal projection diameter of hole should be not more than the diameter of water main; The external diameter of sleeve pipe must be able to cover slight crack, small holes fully.
Although the above has described the present invention with exemplary embodiment by reference to the accompanying drawings, those of ordinary skills should be clear, in the situation of the spirit and scope that do not break away from claim, can carry out various modifications to above-described embodiment.
