Description
Technical field
The utility model relates to gas pipeline welding technology field, specifically a kind of outdoor wall body fuel gas pipeline welds counterpart
Device.
Background technique
Pipe gas is widely used in civilian and industrial circle as a kind of clean fuel.But combustion gas is inflammable and explosive simultaneously,
The installation maintenance of its pipeline is of crucial importance, and gas pipeline caliber is greater than DN50 or the use of pressure is more than 10KPa under normal circumstances
It is appropriate to the occasion using be welded to connect, currently, the welding of pipeline mostly ground complete, but in some special cases (such as with reserved opening
When connection or rush repair), it needs to weld the pipeline on wall, since wall limits, is not available conventional welding
Contra-aperture device, therefore, it is necessary to design a kind of new welding contra-aperture device, to solve this problem.
Summary of the invention
The purpose of this utility model is to propose that a kind of outdoor wall body fuel gas pipeline welding contra-aperture device can by the present apparatus
To realize the butt welding to wall pipeline, welding quality can be effectively improved, shortens the construction time.
The utility model uses following technical scheme: a kind of outdoor wall body fuel gas pipeline welding contra-aperture device, including upper solid
Determine frame and lower fixed frame, upper holder is fixedly connected by fastening bolt with lower fixed frame；The lower fixed frame is outer by two
The identical V-type card of shape is connected by screw rod and is formed, and V-type card both ends are symmetrically arranged with otic placode, is provided in the middle part of otic placode to pacify
The through-hole of fixing bolt is loaded, VXing Ka bottom centre is provided perpendicular to the connecting plate of V-groove axis, is provided in the middle part of connecting plate
To install the through-hole of screw rod；The upper holder is made up of the identical semicircle snap ring of two shapes screw rod connection,
Snap ring both ends are provided with 90 degree of otic placodes, are provided with the through-hole to install fastening bolt in the middle part of otic placode, in snap ring lateral surface
Portion is provided perpendicular to the connecting plate of snap ring axial line, and the through-hole to install screw rod is provided in the middle part of connecting plate；
The V-type khaki V-groove inner surface is coated with flexible material, the axle center of the through-hole on V-type card bottom connecting plate
Line is parallel to the longitudinal axis of V-groove.
Its inner surface of the snap ring is coated with flexible material, the axis parallel of the connecting hole of the outer middle side part of snap ring in
The axial line of snap ring.
The beneficial effects of the utility model are: the utility model is simple and compact for structure, assembling easy to disassemble, one can be complete
At pipeline butt, welding operation, suitable for the construction in small space；Using the composite structure of V-type card and snap ring, so that clamping
Securely, nozzle is not susceptible to misplace；Clamping position is coated with flexible material, avoids and causes mechanical damage to gas pipeline.
