Abstract
The utility model relates to a blocking and clamp device with pressure, which is composed of an upper hoop, a lower hoop and a fastening bolt. The upper hoop and the lower hoop are jointed via a pin shaft or a hinge. The upper hoop is provided with a pressure relief device which is composed of a screw rod, a valve and a pressure relief channel. The screw rod is connected with the valve; the upper hoop is provided with a tapered table top over against the upper part of the valve, and the tapered table top can realize the sealing with the valve can be concentric sphere or a circular truncated cone. The inner surface of the upper hoop is provided with a groove. The utility model has the advantages of safe operation, convenience, and favorable effect when the utility model is used for blocking in high-pressure pipe.
Description
The utility model relates to a kind of Pipe leakage stopper, is particularly suitable for the mending-leakage after high pressure oil transportation (gas, water) pipe perforation is used in the oil field.
The leak stoppage tool of field use is to severing with dry pipe at present, shed the pressure (promptly stop production) of leakage pipeline, the two halves dry pipe is wrapped in perforation place of pipeline, tightly wrap with steel wire then, or more renewing pipeline section, its deficiency is: the ability leak stopping 1, must stop production; 2, sealing is poor, and is not high pressure resistant; 3, complex structure, operation inconvenience.
The objective of the invention is to overcome shortcoming of the prior art, a kind of simple in structure, handling safety is provided, need stopping production and good airproof performance, high voltage bearing pipe plugging reading card device.
The purpose of this utility model is achieved in that blocking and clamp device is made up of front band, lower catch hoop, tight state bolt, front band is connected by bearing pin or hinge with lower catch hoop, pressure relief device is arranged on the front band, pressure relief device is made of screw rod, valve, pressure release passage, in front band, there is a garden conical surface to realize sealing with valve, during leak stopping, open pressure relief device, in the front band inner surface recesses, tumble in asbestos packing or rubber pad, with clamping bolt fixedly front band and lower catch hoop, close pressure relief device again, promptly finish leak stopping
The utility model handling safety, easy, applied widely, when the high pressure pipe line leak stopping of several places, all obtained satisfied effect.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a pressure sealing reading card device structural representation
Among the figure: front band-1, screw rod-2, valve-3, groove-4, clamping bolt-5,6,7, lower catch hoop-8, bearing pin or hinge-9, pressure release passage-10, taper table top 11.
Fig. 1 is the utility model most preferred embodiment:
The pressure sealing reading card device is by front band 1, lower catch hoop 8, clamping bolt 5,6,7, form, front band 1 is connected by bearing pin or hinge with lower catch hoop 8 one sides, opposite side has bolt hole, use for clamping bolt, front band 1 is more bigger or identical than the caliber of pipeline to be blocked up with the caliber that lower catch hoop 8 forms, front band 1 is provided with a pressure relief device, it is by screw rod 2, valve 3, pressure release passage 10 constitutes, valve 3 can be the garden platform, adopted ball mechanism in the ball in the present embodiment, be that screw rod 2 bottoms are a bead, valve ball 3 encases bead and can rely on bead that inclined to one side biography takes place and finds sealing station automatically, and front band 1 is a taper table top 11 over against the position of valve ball 3, can realize sealing with valve ball 3, the internal surface of front band 1 has a groove 4, can inlay asbestos packing or rubber pad.According to the pipeline internal medium difference, select corresponding asbestos packing or rubber pad before the leak stopping, be embedded in the groove 4, turn screw rod 2 during leak stopping valve 3 is moved down, leave the garden conical surface, pressure release passage 10 is opened like this, leakage flows out by pressure release passage 10, utilize pipe wrench or other instrument that front band 1 and lower catch hoop 8 are closed tightly, fastening by clamping bolt 5,6,7, finish and check card, turning screw rod 2 then moves up, make valve 3 and taper table top 11 be adjacent to sealing, pressure release passage 10 is closed, and finishes leak stopping.
