Abstract
A pressure pipeline pressure relief device comprises a screw drill, a spray guard, an escape pipe, a coupling and an oil transporting pipeline, the coupling is welded on the oil transporting pipeline, the spray guard is in threaded connection with the coupling, external threads of the screw drill are screwed with female threads of the upper portion of the spray guard, the escape pipe is welded on the side face of the spray guard, the lower end of the screw drill is conic, hardness of the conic portion at the lower end of the screw drill is HRC 45-55, holes are formed in the oil transporting pipeline simply by rotating the screw drill, oil gases sprayed out after holes are formed are controlled by the spray guard, the oil gases flow out through the escape pipe and are recovered, and therefore the pressure pipeline pressure relief device is safe and reliable during processing of flow stopping of oil gases in winter and solidification of pipelines, no personal injury accidents happen, no environmental pollution is produced, and the pressure pipeline pressure relief device has significant economical benefits and social benefits.
Description
Technical field
The utility model relates to the device on the petroleum pipeline of oil field, is a kind of pressure line pressure relief device.
Background technique
Can solidify after the interior oil gas of pipeline in winter arrheas, cause pipeline to stop up, can't carry oil gas again, need earlier the oil gas that solidifies in the pipeline is added and to carry after pyrolysis is coagulated.Pressure increase when preventing that adding pyrolysis coagulates in the pipeline causes line fracture, need segmentation perforate pressure release on pipeline.The method of pressure release at present is to pound the hammer drill perforate with sledgehammer on pipeline, pound hole-opening after, the high-pressure oil gas in the pipeline can eject at once, cause the loss of environmental pollution and oil gas, operating environment variation, constructional difficulties, also cause personal injury accident easily, produce heavy economic losses.
Summary of the invention
The purpose of this utility model is a kind of pressure line pressure relief device of design, and it can not be sprayed during the perforate pressure release on petroleum pipeline, prevents that human injury from taking place, and avoids environmental pollution.
The purpose of this utility model is achieved in that and comprises a brill, spray guard, blow-down pipe, box cupling, petroleum pipeline, box cupling is welded on the petroleum pipeline, spray guard is threaded with box cupling, the outside thread that silk bores and the box thread on spray guard top screw, blow-down pipe is welded on the side of spray guard, and it is taper that silk bores the lower end.
The tapered portion hardness that silk bores the lower end is HRC45-55.
The beneficial effects of the utility model are: rotation silk just bores can perforate on petroleum pipeline, the oil gas that sprays after the perforate is controlled by spray guard, be recovered through the blow-down pipe outflow, therefore, use the utility model to arrhea when solidifying pipeline handling winter oil gas, safe and reliable, personal injury accident can not take place, do not produce environmental pollution, have remarkable economic efficiency and social benefit.
Description of drawings:
Accompanying drawing 1 is the utility model embodiment's a erection drawing.
Embodiment:
Describe below in conjunction with the example of executing of accompanying drawing the utility model reality.
As seen from the figure, the example of executing of the present utility model comprises silk brill 1, spray guard 2, blow-down pipe 3, box cupling 4, petroleum pipeline 5, box cupling 4 is welded on the petroleum pipeline 5, spray guard 2 is threaded with box cupling 4, the outside thread of silk brill 1 and the box thread on spray guard 2 tops screw, blow-down pipe 3 is welded on the side of spray guard 2, and it is taper that silk bores 1 lower end.The tapered portion hardness that silk bores 1 lower end is HRC45-55.
Blow-down pipe 3 communicates with spray guard 2, when needing the perforate pressure release, the rotation silk bores 1, the tapered portion hardness of silk brill 1 is higher than the hardness of petroleum pipeline 5, be equivalent to drill bit during rotation and drill, petroleum pipeline 5 can be drilled, thereby open hole at petroleum pipeline 5 at petroleum pipeline 5, high-pressure oil gas flows out from drill hole, reclaims through blow-down pipe 3.
Claims (2)
1. pressure line pressure relief device, comprise that silk bores (1), spray guard (2), blow-down pipe (3), box cupling (4), petroleum pipeline (5), box cupling (4) is welded on the petroleum pipeline (5), it is characterized in that: spray guard (2) is threaded with box cupling (4), silk bores the outside thread of (1) and the box thread on spray guard (2) top screws, blow-down pipe (3) is welded on the side of spray guard (2), and it is taper that silk bores (1) lower end.
