One important component of pipeline engineering, compensator play an important role in terms of ensureing the long-term normal operation of pipeline.
A kind of expansion joint made of FlexbleJoint metal bellows.It can stretch in the axial direction, also allow a small amount of
Bending.Common axial type FlexbleJoint, with carrying out axial length compensation on pipeline.FlexbleJoint in the prior art
Bellows and the flange at both ends be mostly by the way of being welded to connect, due to bellows thinner thickness, welding difficulty compares
Greatly, it is difficult to control welding quality and cost, this connection type has much room for improvement.The connection otic placode of existing flange upper connecting rod simultaneously
All it is on the ring flange of later stage welding, the solder joint position between otic placode itself and ring flange easy tos produce asking for fracture
Topic, influences the quality of entire compensator, this problem is also to have much room for improvement.
Utility model content
To solve the above problems, the utility model proposes a kind of FlexbleJoints of end flanging positioning structure.
The technical solution of the utility model is：A kind of FlexbleJoint of end flanging positioning structure, including bellows and
The ring flange of bellows both ends installation, is connected by screw rod between two ring flanges, it is characterized in that：The ring flange is integrated
The ear of molding ring flange, several upper screw rod installations of the ring flange is an integral molding structure with flange disc main body；
Ear be equipped with screw rod mounting hole, on flange disc main body be equipped with several flanges dock mounting hole, flange dock mounting hole with
Screw rod mounting hole interlaced arrangement, circumference where the diameter of circumference is less than screw rod mounting hole where several flanges dock mounting hole
Diameter；The bellows includes the flange construction section of intermediate bellows segment and both ends, and the bellows segment is divided along its length
It is furnished with several ripples protrusion, flange construction section includes one section of straight pipe being connect with bellows segment, and in straight pipe end
The positioning flange of outside roll forming, for the inner hole sleeve of the ring flange on straight pipe, flange is located at the outside of ring flange
Position limiting structure, the ripple protrusion of the most end of the medial surface face bellows segment of ring flange are formed to ring flange on face.
The ripple protrusion of the most end of the bellows segment, straight pipe, flange collectively constitute the clamping of an annular groove-shaped
Slot, the ring flange is located in the holding tank to be gripped by the ripple protrusion and flange of most end.
If the screw rod between the ring flange at the both ends is the combined type pull rod of a adjustable-length, each combined type pull rod
The left-handed screw and right handed screw for respectively symmetrically passing through the bolt hole on two ring flanges including two, two screw rod inner ends are screwed into
In the two-way nut common to one, the rotation of the two-way nut can adjust the length of the combined type pull rod.
The bellows is integrally made of stainless steel.
The technique effect of the utility model
The FlexbleJoint of the end flanging positioning structure of the utility model, ring flange is an integral structure, in lift method
The arrangement intensity of FlexbleJoint is also improved while blue self-strength, the flange of roll forming is on the one hand as limiting
The structure of ring flange position on bellows is also used as pressing from both sides on the other hand after the compensator and pipe end flanged joint
Tight washer is used, and has sealing function to the connection of pipeline end flanges and compensator flange.On the flange and conventional flange disk
Waterline has the same sealing effect, and eliminates the process of welding, greatly improves product quality, and energy conservation and environmental protection in this way should
Ring flange is not contacted with the medium in pipeline, and ring flange is avoided to be corroded and cause leakage accident.

Specific implementation mode
Embodiment one：Referring to Fig. 1-3, a kind of FlexbleJoint of end flanging positioning structure in figure, including bellows and
The ring flange of bellows both ends installation, is connected by screw rod between two ring flanges, it is characterized in that：The ring flange is integrated
The ear of molding ring flange, several upper screw rod installations of the ring flange is an integral molding structure with flange disc main body；
Ear be equipped with screw rod mounting hole, on flange disc main body be equipped with several flanges dock mounting hole, flange dock mounting hole with
