Abstract
Broadside malleable cast iron tube coupling spare, the second extension interface of first interface that is equipped with respectively including pipeline section, pipeline section both ends and second interface, the first extra long interface of connecting first interface, connection second interface, its characterized in that the first extra long interface of an interface connection, the 2nd interface connection second extension interface at pipeline section both ends for casting one shot forming's overall structure. The utility model provides the high corrosion -resistant ability of galvanized pipe improves life, and is safe, sealed, simple to operate's broadside malleable cast iron tube coupling spare.
Description
Technical field
This utility model is related to air delivering pipeline connector, more particularly to broadside malleable cast iron pipeline connector.
Background technology
Gasification is built and is developed, and is to improve one of important measures of city people's living standard and quality.Fuel gas transmission
Too busy to get away pipe-line system, and the connection of pipeline be unable to do without connector, such as threeway, elbow etc..Elbow wherein using at present etc.
Pipe fitting, the internal thread segment of connector is short, causes the external screw thread being attached thereto the galvanized pipe at end to expose, and is highly prone to corrode, leads to
Trommel, mechanical strength weakens, and easily ruptures at screwed connection, reduces the service life of galvanized pipe, combustion easily simultaneously
Diarrhea due to stagnation of QI dew accident.
Utility model content
The technical problems to be solved in the utility model is to provide screw thread at the galvanized pipe that a kind of effective protection connects and does not expose
Outside, improve galvanized pipe corrosion resistance, improve service life, safely,
Sealing, broadside malleable cast iron pipeline connector easy for installation.
Employed technical scheme comprise that：
Broadside malleable cast iron pipeline connector, the first interface being respectively arranged at two ends with including pipeline section, pipeline section and second interface,
Connect the first lengthening interface of first interface, the second of connection second interface lengthens interface.The first of described pipeline section two ends connects
Mouth connects first and lengthens interface, second interface connection the second lengthening interface for casting one-time formed overall structure.
Above-mentioned first lengthening interface and the second lengthening interface be pipeline connecting parts widen outer L, described widen outer L
Inner chamber be provided with the groove h that can encrypt envelope from a section of port.
The above-mentioned outer L that widens removes groove h part for screw thread, and the screw thread consistent with pipeline section interface thread.
This utility model has the lengthening interface of integration respectively by two seams, at the galvanized pipe that energy effective protection connects
Screw thread improves corrosion resistance, improves pipeline service life outside being not exposed to.In addition, improve the security performance of pipeline,
Elbow interface originally is short, and the thread segment that the galvanized pipe of connection exposes leads to trommel because being highly prone to corrode, mechanicalness
Can weaken, sealing effectiveness is poor, easily gas leakage occur, cause the accident.This utility model has the outer L widening, and increased machinery
Performance, groove h is matched with the fluid sealant in construction or adhesive tape, considerably increases sealing, security performance is high, and installation side
Just.
Brief description
Fig. 1 is the structural representation of this utility model embodiment.
Specific embodiment
Broadside malleable cast iron pipeline connector（Taking elbow as a example）, connect including pipeline section 1, pipeline section are respectively arranged at two ends with first
Mouth 2 and second interface 4, the first lengthening interface 3 connecting first interface, the second lengthening interface 5 of connection second interface.Described
The first interface 2 at pipeline section 1 two ends connects the first lengthening interface 3, second interface 4 connects the second lengthening interface 5 and once becomes for casting
The overall structure of type.Described first lengthening interface 3 and the second lengthening interface 5 be pipeline connecting parts widen outer L, described widen
The inner chamber of outer L is provided with the groove h that can encrypt envelope from a section of port.The described outer L that widens removes groove h part for screw thread,
And the screw thread consistent with pipeline section interface thread 6, constitute broadside malleable cast iron pipeline connecting bend.
Claims (3)
1. broadside malleable cast iron pipeline connector, the first interface (2) and second being respectively arranged at two ends with including pipeline section (1), pipeline section
Interface (4), the first lengthening interface (3) connecting first interface, the second lengthening interface (5) of connection second interface, its feature exists
First interface (2) in described pipeline section (1) two ends connects the first lengthening interface (3), second interface (4) connects the second lengthening and connects
Mouth (5) is to cast one-time formed overall structure.
2. broadside malleable cast iron pipeline connector according to claim 1 is it is characterised in that described first lengthening interface
(3) and the second lengthening interface (5) be pipeline connecting parts widen outer L, the described inner chamber widening outer L is provided with from port one
Section can encrypt the groove h of envelope.
3. broadside malleable cast iron pipeline connector according to claim 2 is it is characterised in that the described outer L that widens removes
Groove h part is screw thread, and the screw thread consistent with pipeline section interface thread (6).
