Abstract
The utility model provides a no weld bond ji huiguandao of high pressure, its characterized in that: include square trunk line, branch road pipeline and be located sealed pad between square trunk line and the branch road pipeline, the branch road pipeline is a butt welding side of having and attaches the blue or round pipe that attaches the connection orchid of connection, the side attaches the connection orchid or the circle attaches the blue and trunk line fixed connection of connection, upward it is provided with the through -hole to correspond the position with the branch road pipeline in square trunk line side, around the through -hole processing have at least four with the side attaches the connection orchid or the circle attaches the flange joint of connecing size assorted screw hole, high -pressure pipeline T -shaped junction welding seam fracture problem has thoroughly been solved to this scheme.
Description
Technical field
The utility model relates to high pressure pipe line interconnection technique field, particularly relates to high voltage charge road and bypass line interconnection technique, is specially high-pressure weldless mouth Ji Huiguandao.
Background technique
From last century the nineties cartridge valve hydraulics after China's popularization and application, the each big-and-middle-sized forging equipment (hydraulic press) in the whole nation is improved, " oil hydraulic press " many pumps direct-supplying type, PLC program control, the time of more than ten years is used widely, in the hydraulic power unit of various press, multiple oil hydraulic pump pipeline all collect be welded on circular high voltage conveying main pipeline on, this T-shaped welded pipe line has the following disadvantages: 1, pipeline is longer, welding capacity is large, and welding procedure is comparatively difficult to ensure card; 2, in equipment running process, no load running and high-pressure service frequency larger, resonance is strong, easily make that tube wall is flexible, expansion probability frequent, cause all pipe welding ports to replace crackle, snap, high-pressure leakage, seriously affect productions, appearance fire hazardous adversely, also to carry out during repairing that gas cutting isolates, polishes, repair welding, very easily raw for inner-walls of duct iron scale, welding slag are fallen in hydraulic oil, major injury is caused to each hydraulic element, blocking, card valve.
Summary of the invention
For thoroughly solving high voltage charge road and bypass line T-shaped joint weld bond snaps the series of problems brought, the utility model provides a kind of high pressure pipe line of new linkage structure.
The scheme that the utility model is taked is: high-pressure weldless mouth Ji Huiguandao, comprise square main pipeline, bypass line and between described square main pipeline and bypass line for seal sealing gasket, bypass line and main pipeline joint are in " fourth " font, bypass line is the pipe of one end side of being welded with attachment flange or circle attachment flange, and the side's attachment flange in bypass line or circle attachment flange are fixedly connected with main pipeline; Square main pipeline side is provided with through hole with bypass line corresponding position, square pipe is communicated with by this through hole with bypass line, the surrounding of described through hole is processed with at least four and is attached flange or the round tapped hole being attached Flange joint size and matching with described side, and bypass line is by being bolted on square main pipeline of mating with described tapped hole.
As optimization, described square main pipeline is forge piece, and for ensureing pipeline strength, square main pipeline wall thickness is not less than 60mm.
As optimization, described square pipe side is arranged at intervals with projection, and the tapped hole that the through hole that square pipe is communicated with bypass line, bypass line are fixed all is positioned in described projection, to strengthen through hole pipeline strength, increases screw thread place wall thickness.
As optimization, described sealing gasket is red copper pad, avoids long-time high temperature, high pressure, oil immersion to the damage of sealing gasket.
As optimization, the through hole that square main pipeline side is arranged with bypass line corresponding position is manhole, convenient processing, and be attached flange or circle with side, to be attached flange matching better.
Compared with prior art, the beneficial effects of the utility model are: connect by changing Placement into bolt by welding, thoroughly solve high pressure pipe line T-shaped connection part weld cracking problem, thus avoid the problem such as leakage of oil, oil contamination.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described clearly and completely.
Embodiment one, according to Fig. 1-3, high-pressure weldless mouth Ji Huiguandao, comprise square main pipeline 2, bypass line 1 and the sealing gasket 3 between square main pipeline 2 and bypass line 1, described bypass line 1 comprises the side's attachment flange 5 and pipe 4 that are welded to connect, be fixedly connected with main pipeline 2 by side's attachment flange 5, side's attachment flange 5 operative norm JB/T2007-84, comprises screw 3, adapter 10 and flange 6; Square main pipeline 2 is obtained by forging, wall thickness is 62mm, described square main pipeline 2 side is provided with protruding 8 with bypass line 1 corresponding position, on protruding 8, is provided with manhole 9, be processed with around manhole 9 at least four with the tapped hole 7 being just attached flange 5 Conncetion cimension and matching; Sealing gasket 3 elects red copper pad as.
Embodiment two, when branch road caliber is larger, the side's attachment flange in embodiment one are replaced by circle attachment flange, and with described, the position dimension of tapped hole 7 and aperture justify that to be attached flange suitable, all the other are with embodiment one.
The above is only preferred implementation of the present utility model; protection domain of the present utility model is also not only confined to above-described embodiment; all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model; should be understood that; for those skilled in the art; do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
