Description
Technical field
The utility model relates to a kind of pipeline pressure testing device, specifically a kind of plug-in type PRESSURE TESTING BLIND FLANGE.
Background technique
In the construction and maintenance process of petrochemical equipment, pressure testing need be carried out to pipeline, common pressure testing mode installs at pipeline peak or distalmost end to carry out pressure testing with blow-down pipe and manometric PRESSURE TESTING BLIND FLANGE, but the blow-down pipe of existing most PRESSURE TESTING BLIND FLANGE and pressure gauge are all the end faces being arranged on blind plate, for the equipment that some structures are compacter, its pipeline peak or distalmost end place do not have enough spatial placement blow-down pipes and pressure gauge, therefore be difficult to complete pressure testing to whole pipeline, when equipment runs, there is certain potential safety hazard.In order to reduce the blow-down pipe on blind plate and the pipeline axial space shared by pressure gauge, those skilled in the art propose in blind plate, arrange curved hole, the outlet in curved hole is arranged on the annular sidewall of blind plate, but difficulty of processing is very big under prior art conditions for the curved hole in blind plate, in working process, hole wall is fragile splits, cause defect rate in production process higher, be difficult to carry out large-scale industrial production.
Model utility content
The purpose of this utility model be overcome that existing pipeline pressure test blind plate exists defect, provide a kind of blow-down pipe and pressure gauge to be arranged on blind plate annular sidewall and be easy to the plug-in type blind plate produced.
The utility model for achieving the above object, be achieved through the following technical solutions: comprise blind plate, groove is offered in the center of circle of a blind plate end face between outer edge, groove is arranged along the radial direction of blind plate, install bend pipe in groove, bend pipe comprises the first straight tube and the second straight tube, is connected between the first straight tube with the second straight tube by elbow, second straight tube embeds in groove, arranges sealing obturator between the second straight tube and groove.Described sealing obturator is solder.Described sealing obturator comprises gland, gland and groove fit, and gland is arc shaped surface near the one side of the second straight tube, and gland both sides arrange fixed plate, and fixed plate is connected with blind plate by bolt.Described fixed plate offers counter sink, and the head of bolt is positioned at counter sink.The second straight tube periphery wall in groove arranges rubber gasket.Second straight tube outer wall arranges bulge loop, and bulge loop contacts with rubber gasket.
The utility model has the advantage of: take pipeline axial space minimum, the pipeline peak of limited space or distalmost end can be arranged on and the position such as between pipeline and the flange of equipment interconnection, pressure testing is carried out to whole piece pipeline, be conducive to the potential safety hazard eliminating petrochemical equipment, its structure fabrication is easy, need, in blind plate internal bore, not be conducive to carrying out large-scale industrial production etc.

Embodiment
Plug-in type PRESSURE TESTING BLIND FLANGE described in the utility model comprises blind plate 1, groove 2 is offered in the center of circle of blind plate 1 one end faces between outer edge, groove 2 is arranged along the radial direction of blind plate 1, in groove 2, bend pipe is installed, bend pipe comprises the first straight tube 3 and the second straight tube 4, be connected by elbow between first straight tube 3 with the second straight tube 4, the second straight tube 4 embeds in groove 2, arranges sealing obturator between the second straight tube 4 and groove 2.The utility model can realize pressure gauge and the blow-down pipe that is connected with pressure gauge to be arranged in the annular side of blind plate 1, enable PRESSURE TESTING BLIND FLANGE described in the utility model be arranged on the pipeline peak of limited space or distalmost end and the position such as between pipeline and the flange of equipment interconnection, take pipeline axial space minimum.Only need offer groove 2 and need in blind plate 1 internal bore when the utility model makes on blind plate 1, manufacture difficulty is low, be conducive to carrying out large-scale industrial production.
Sealing obturator described in the utility model can adopt solder, namely, after installation bend pipe, the second straight tube 4 in bend pipe is welded with the gap between groove 2, plays seal action, but the manufacturing efficiency of this sealing means is lower, and welder is needed to possess higher welding technical ability.In addition, sealing obturator described in the utility model also can adopt modular construction, its preferred structure is as follows: described sealing obturator comprises gland 5, gland 5 coordinates with groove 2, and gland 5 is arc shaped surface 6 near the one side of the second straight tube 4, and gland 5 both sides arrange fixed plate 7, fixed plate 7 is connected with blind plate 1 by bolt 8, this structure is by unified Mold Making, and manufacturing efficiency is high, requires relatively low to the operative skill of assembler.
The utility model is the sealing state preventing bolt 8 from affecting blind plate 1 and tube contacts face, and can offer counter sink 9 on described fixed plate 7, the head of bolt 8 is positioned at counter sink 9.
The utility model is strengthen the sealing effect in groove 2 further, can arrange rubber gasket 10 by the second straight tube 4 periphery wall in groove 2.Rubber gasket 10 can fill up the gap around the second straight tube 4 after extruding by groove 2 and gland 5.Cause seal failure for preventing the aging rear elasticity of rubber gasket 10 from reducing, can arrange bulge loop 11 at the second straight tube 4 outer wall described in the utility model, bulge loop 11 contacts with rubber gasket 10.Bulge loop 11 can strengthen the crushing strength to rubber gasket 10, prevents the seal failure of rubber gasket 10.
