Description
Technical Field
The invention relates to the technical field of high-temperature blocking of pipelines under pressure, in particular to a high-temperature barrel type blocking head.
Background
In the use process of an oil gas conveying pipeline, the pipeline is locally corroded, deformed or damaged due to self or external factors and the like, so that potential safety hazards of the pipeline are generated.
SUMMERY OF THE UTILITY MODEL
The invention provides the high-temperature barrel type plugging head which is simple in structure, safe, reliable and better in sealing effect.
A high-temperature barrel type plugging head aims to solve the problem that the existing plugging technology cannot meet the plugging operation at high temperature.
The technical scheme adopted by the invention for solving the technical problem is as follows: the invention relates to a high-temperature barrel type plugging head which comprises an arc-shaped copper sheet 1, a body 2, a slide way 3, a fastening screw 4, a pin shaft 5, an upper sliding plate 6, a positioning rod 7, a spring 8 and a lower sliding plate 9. The method is characterized in that: the top board 6, lower slide 9 link together through round pin axle 5 with both sides slide 3, and when the relative direction motion was done with lower slide 9 to top board 6, round pin axle 5 can freely slide in the chute of both sides in top board 6, lower slide 9, when top board 6 and lower slide 9 moved to the inboard simultaneously, outwards extruded slide 3 simultaneously through the tapering of top board 6 and lower slide 9 both sides to drive both sides arc copper sheet 1 and expand to the outside simultaneously. The arc copper sheet 1, the body 2 and the slide 3 are connected and fastened together through the fastening screw 4, the upper sliding plate 6 is in threaded connection with the positioning rod 7, the lower end of the positioning rod 7 penetrates through a center hole of the lower sliding plate 9, and the spring 8 is assembled between the upper sliding plate 6 and the lower sliding plate 9.
The slideway 3 is matched with the upper sliding plate 6 through a groove.
The slideway 3 is matched with the lower slide plate 9 through a groove.
The pin 5 can slide freely in the chutes at the two sides of the upper sliding plate 6 and the lower sliding plate 9.

Detailed Description
As shown in figure 1, the high-temperature barrel type blocking head comprises an arc-shaped copper sheet 1, a body 2, a slide way 3, a fastening screw 4, a pin shaft 5, an upper sliding plate 6, a positioning rod 7, a spring 8 and a lower sliding plate 9. The method is characterized in that: the device comprises an arc copper sheet 1, a body 2, a slide way 3, a fastening screw 4, a pin shaft 5, an upper sliding plate 6, a positioning rod 7, a spring 8 and a lower sliding plate 9. The method is characterized in that: the top board 6, lower slide 9 link together through round pin axle 5 with both sides slide 3, and when the relative direction motion was done with lower slide 9 to top board 6, round pin axle 5 can freely slide in the chute of both sides in top board 6, lower slide 9, when top board 6 and lower slide 9 moved to the inboard simultaneously, outwards extruded slide 3 simultaneously through the tapering of top board 6 and lower slide 9 both sides to drive both sides arc copper sheet 1 and expand to the outside simultaneously. The arc copper sheet 1, the body 2 and the slide 3 are connected and fastened together through the fastening screw 4, the upper sliding plate 6 is in threaded connection with the positioning rod 7, the lower end of the positioning rod 7 penetrates through a center hole of the lower sliding plate 9, and the spring 8 is assembled between the upper sliding plate 6 and the lower sliding plate 9.
The slideway 3 is matched with the upper sliding plate 6 through a groove.
The slideway 3 is matched with the lower slide plate 9 through a groove.
The pin 5 can slide freely in the chutes at the two sides of the upper sliding plate 6 and the lower sliding plate 9.
The plugging process of the high-temperature barrel type plugging head is shown in fig. 2: welding a plugging cross joint, cutting off a cut-off hole, sending a high-temperature barrel type plugging head into a four-way pipe fitting by using a lower plugging device, aligning arc-shaped copper sheets 1 on two sides of the high-temperature barrel type plugging head with a pipeline cut, then pressing down the plugging head to enable a positioning rod 6 of the plugging cross joint to be inserted into a positioning hole of the plugging cross joint, and simultaneously pressing outwards a slide 3 through the tapers on two sides of an upper slide plate 6 and a lower slide plate 9 when the upper slide plate 6 and the lower slide plate 9 move inwards at the same time, so as to drive the arc-shaped copper sheets 1 on two sides to expand outwards at the same time, continuously pressing down the plugging head, and enabling a sealing surface of the copper sheet 1 to be tightly attached to the position of the section of the opening of the pipeline, thereby completing plugging.
