Abstract
The utility model discloses a kind of reinforcing formula non-metal expansion joints, it includes quiet flange, dynamic flange, adapter tube, nonmetallic mesh belt, reducer pipe and clip.The adapter tube of the reducer pipe smaller diameter end housing clearance fit, reducer pipe larger diameter end and adapter tube free end are separately connected quiet flange, all mating dynamic flange of every quiet flange.The nonmetallic mesh belt is wound into tubular and covers and is attached on adapter tube and reducer pipe larger diameter end outer wall, and both ends lap-joint is clamped with clip respectively, constitutes reinforcing formula axial seal connection structure.Use the nonmetallic mesh belt of clamp connection in the utility model, such connection structure is simple, install convenient, reliable clamping, uniform force, sealed reliable.In addition to this, clip also significantly increases the rigidity of nonmetallic mesh belt in the structure, this invigoration effect is conducive to non-metal expansion joint and makees flexible deformation in normal state, and good operating condition greatly improves the service life of non-metal expansion joint.
Description
Technical field
The utility model belongs to pipe safety engineering device technique field, in particular, the utility model relates to a kind of nonmetallic
Expansion joint, especially a kind of reinforcing formula non-metal expansion joint.
Background technique
Non-metal expansion joint is a kind of traditional pipe safety device, and application is very extensive.The industry is also according to product knot
Non-metal expansion joint is referred to as nonmetallic to be flexible coupling by the feature of structure.Because temperature, pressure changes when heat distribution pipeline is run, phase is generated
The displacement or axial thrust answered, since axial thrust has stronger destructiveness, so must configuring pipes benefit in heat distribution pipeline
Device is repaid, axial thrust is absorbed with this.The reason of heat distribution pipeline of some industries is because of structure must mating non-metal expansion joint.From
Say that non-metal expansion joint is exactly a kind of flexible member in structure, it can be from position caused by multi-faceted absorption or compensation axial thrust
It moves.The non-metal expansion joint of the prior art is made of nonmetallic circle band and both ends metal adapter tube or additional flange, and when installation is usual
It is connect by both ends metal adapter tube or additional flange with pipeline.Between the nonmetallic circle band of non-metal expansion joint and metal adapter tube
Connection, generallys use and is bolted, and since the bore of non-metal expansion joint is relatively large, installation is needed with being much bolted.
Although bolt can be realized effective connection, amount of machining is big, and assembly time is long, consumptive material is more, along with frequent compensating movement is easy
Cause bolt falling, it is also possible to because of circle band edge damage nonmetallic caused by bolt looseness.Generally speaking, heavy caliber or super large caliber
Non-metal expansion joint inside should not be connected with.
Utility model content
The utility model proposes that a kind of main structure is constant, connection is quick, stress is equal mainly for the deficiencies in the prior art
Even, good airproof performance reinforcing formula non-metal expansion joint.
The utility model is achieved through the following technical solutions technical goal.
Reinforcing formula non-metal expansion joint, it includes quiet flange, dynamic flange, adapter tube, nonmetallic mesh belt, reducer pipe and clip.
The adapter tube of the reducer pipe smaller diameter end housing clearance fit, reducer pipe larger diameter end and adapter tube free end are separately connected quiet method
Orchid, all mating dynamic flange of every quiet flange.It is theed improvement is that: the nonmetallic mesh belt is wound into tubular and covers and is attached to
On adapter tube and reducer pipe larger diameter end outer wall, both ends lap-joint is clamped with clip respectively, constitutes reinforcing formula axial seal connection knot
Structure.
In above structure, clip is made of two semicircle shape components, and both ends are tightened by bolts.
In above structure, the radially connected one piece of grounded plate of flange outer wall is moved.
In above structure, the reducer pipe is seamless pipe.
The utility model compared with prior art, has the positive effect that:
1, clip clamping structure is simple, is easy to make, reliable clamping；
2, nonmetallic mesh belt is clamped by clip, and due to uniform force, sealing effect is good；
3, nonmetallic mesh belt is clamped by clip, install convenient, and joint efficiency is high.
Detailed description of the invention
Fig. 1 is the utility model structural profile illustration.
Fig. 2 is that partial structurtes enlarged diagram, displaying clip are tightened by bolts structure at A in Fig. 1.
Specific embodiment
Below according to attached drawing and in conjunction with the embodiments, the utility model is described in further detail.
Reinforcing formula non-metal expansion joint shown in FIG. 1, it include quiet flange 1, dynamic flange 2, adapter tube 3, nonmetallic mesh belt 4,
Reducer pipe 5 and clip 6.The reducer pipe 5 is seamless pipe, and the adapter tube 3 of smaller diameter end housing clearance fit, two are coaxially socketed
Pipeline forms the diversion pipe of expansion joint.5 larger diameter end of reducer pipe and 3 free end of adapter tube are separately connected quiet flange 1, every quiet method
Orchid 1 all configures 1 dynamic flange 2, and the dynamic flange 2 equipped with end face through-hole is for connecting mating heat distribution pipeline.In the utility model, institute
State nonmetallic mesh belt 4 be wound into tubular and cover be attached on 5 larger diameter end outer wall of adapter tube 3 and reducer pipe, both ends lap-joint uses respectively
Clip 6 clamps.The clip 6 of the utility model application is that one kind is made of two semi-circular shape components, uses bolt at the docking of both ends
Thus locking forms reinforcing formula axial seal connection structure.In order to accomplish reliable ground and convenient for ground connection, the utility model is dynamic
The radially connected one piece of grounded plate 2.1 of 2 outer wall of flange, grounded plate 2.1 are equipped with through-hole and are convenient for user's connecting wire.
Use the nonmetallic mesh belt of clamp connection in the utility model, such connection structure is simple, install convenient, clamping can
It leans on, uniform force, sealed reliable.In addition to this, clip also significantly increases the rigidity of nonmetallic mesh belt in the structure, this, which strengthens, makees
Make flexible deformation in normal state with non-metal expansion joint is conducive to, good operating condition greatly improves non-metal expansion joint
Service life.
