A kind of doubly-closed tube pipeline connector, belong to bulb tube pipeline connector, solve existing bulb tube pipeline connector high to sphere precision, smoothness requirements, sealing surface easy damaged causes the problem of seal failure, for pressurized gas or liquid pipeline system.The utility model comprises spherical joint, connecting-tube nozzle and cap nut, spherical joint is the tubular solid of rotation with axial central through hole, be made up of upper cylindrical section integrally, annular boss, lower cylindrical section and billiard table section, lower cylindrical section surface has annular groove, and it is embedded with O-ring seals.The utility model is when there is wearing and tearing, slight scuffing in the sealing surface that first seals, realize sealing again by second O-ring seals, thus effectively compensate for the defect of spherical joint-taper ozzle sealing configuration, greatly improve joint sealing reliability and life-span.
Description
Technical field
The utility model belongs to pipe joint, is specifically related to a kind of doubly-closed tube pipeline connector, for pressurized gas or liquid pipeline system.
Background technique
Existing pipe joint is mainly used in being interconnected between conduit, it is conventional taper ozzle sealing configuration form, as shown in Figure 1, it comprises spherical joint 10, connecting-tube nozzle 20 and cap nut 30, this structure relies on the extruding of the sphere of spherical joint and the conical surface of connecting-tube nozzle to form potted line, there is joint dimension little, to pipeline fitting to the less demanding advantage of positivity, but high to sphere precision, smoothness requirements.Cause spherical joint, taper ozzle sealing surface degree of finish to decline because manufacturing, filling the processes such as front test, repeated disassembled and assembled or scratch, then can cause sealing structural failure.Because spherical joint is generally welded on conduit two ends, taper ozzle is a part for air path elements structure, once sealing face damage, can only change conduit or air path elements entirety, therefore high to the processing cost that this sealing structure lost efficacy, the cycle is long.
Summary of the invention
The utility model provides a kind of doubly-closed tube pipeline connector, and solve existing bulb tube pipeline connector high to sphere precision, smoothness requirements, sealing surface easy damaged causes the problem of seal failure.
A kind of doubly-closed tube pipeline connector provided by the utility model, comprises spherical joint, connecting-tube nozzle and cap nut, it is characterized in that:
Described spherical joint is the tubular solid of rotation with axial central through hole, and be made up of upper cylindrical section integrally, annular boss, lower cylindrical section and billiard table section successively from top to bottom, described lower cylindrical section surface has annular groove, and it is embedded with O-ring seals;
Described connecting-tube nozzle is also for having the tubular solid of rotation of axial central through hole, and its axial central through hole to be communicated with successively with lower circular hole by upper circular hole, cone shape hole from top to bottom and to form, and connecting-tube nozzle surface has outside thread, for coordinating with described cap nut;
Described cap nut is tubular solid of rotation, and its end face has center hole, and its internal diameter is greater than described upper cylindrical section external diameter but is less than described annular boss external diameter; Cap nut inwall has internal thread, to coordinate with connecting-tube nozzle; Cap nut surface has six terrace with edges, uses to coordinate spanner;
During use, the upper cylindrical section of described joint passes from cap nut center hole, the internal thread of cap nut and the outside thread of connecting-tube nozzle are threaded connection, the conical surface billiard table section of spherical joint being pressed in the cone shape hole of connecting-tube nozzle realizes sealing, the lower cylindrical section of spherical joint coordinates with the upper circular hole of connecting-tube nozzle, realizes secondary seal by described O-ring seals.
The utility model Applicable scope:
A. nominal pressure: be not more than 30MPa;
B. medium temperature :-45 DEG C ~+100 DEG C;
C. working medium: air, HY-8, YH-10.
The utility model is when there is wearing and tearing, slight scuffing in the sealing surface that first seals, realize sealing again by second O-ring seals, thus effectively compensate for the defect of spherical joint-taper ozzle sealing configuration, greatly improve joint sealing reliability and life-span.
The utility model has carried out assembling test on certain product, carry out under loading system mode checking and accepting vibration and qualification vibration test, 600km transport test, 30MPa, 100 inflation/deflation tests, 20 mounting or dismounting tests and 30MPa pressurize in 6 months test, all once pass through, demonstrate its reliable sealability and usability.
