Description
Technical field
The present invention relates to pipeline connection area, and in particular to a kind of saddle electric smelting end cap.
Background technology
Electric smelting saddle type pipe fitting is the passage of fuel gas transmission, is broadly divided into three major types：Straight-through saddle, bypass saddle, closure saddle
Type；Straight-through saddle is used as branch suitable for main pipeline without gas, the not with pressure, pipeline newly laid, replacement threeway, is needed after connection
Special cutting element is wanted, is drilled on main pipeline upon connection, then can be used；Bypass saddle be applied to main pipeline band gas,
Branch is used as in the pipeline of subsidiary low pressure, substitutes threeway, there is the included band of pipe fitting a combination that can cut through supervisor's material wall to cut
Instrument is cut, cuts through supervisor's material using combination cutting element after connection, instrument restores after the completion of cutting, remains in saddle pipe fitting
It is interior, it is the pipe fitting for being constructed with gas；Closure saddle be then exclusively used in repair polyethylene pipe on scratch and tiny air leakage point it is special
Use pipe fitting.
And electric smelting saddle type end cap is then that electric smelting saddle type pipe fitting can be blocked to the device for preventing that combustion gas from flowing out, but it is existing
Electric smelting saddle type end cap simply tightened using bolt electric smelting saddle type end cap be fixed on electric smelting saddle type pipe fitting, easily produce loose
It is dynamic, cause gas leakage.
The content of the invention
The invention aims to provide can place end cap loosen cause gas leakage to cause between end cap and pipe fitting more
Add a kind of saddle electric smelting end cap being brought into close contact.
The present invention is achieved through the following technical solutions：A kind of saddle electric smelting end cap, including end cap body, bolt positioning hole,
First, which is additionally provided with, in the end cap inner body wall shaves shape tooth；Fixing device is additionally provided with the end cap body；The fixing device
Including sealing ring, dynamic clamping head and quiet clamping head, briquetting, trapezoidal pushing block, retaining groove；The sealing ring is arranged in end cap body；Institute
State and be additionally provided with briquetting on the outside of sealing ring；The trapezoidal pushing block is arranged at briquetting both sides；The trapezoidal pushing block is also associated with bullet
Property return unit；The dynamic clamping head and quiet clamping head is arranged in retaining groove；Trapezoidal pushing block on the end cap body also with retaining groove
Coordinate；The dynamic clamping head and quiet clamping head includes the limited block being arranged in retaining groove and the limited block being arranged on trapezoidal pushing block；Institute
State and be arranged with spring between two limited blocks；The end cap body is provided with bolt positioning hole；The retaining groove engages edge
It is arranged to arc；The briquetting is provided with fixture block；The end cap body is provided with the neck coordinated with fixture block.
The present invention promotes the trapezoidal trapezoidal pushing block of pushing block elasticity of compression return unit recessed into screens by pressing briquetting
In groove, the fixture block that briquetting is provided with engages with the neck that end cap body is provided with, this ensures that briquetting can be squeezed closely
Sealing ring is pushed down, the groove coordinated with sealing ring is provided with electric smelting saddle type pipe fitting, briquetting crush seal circle is protected into groove
The effect of sealing has been demonstrate,proved, and has been not easy to slide；It is additionally provided with electric smelting saddle type pipe fitting and shaves shape tooth with first in end cap inner body wall
Second coordinated shaves shape tooth, ensures that it is more not easy to slide so as to cause gas leakage.
The present invention is advantageous in that：1) pressing briquetting promotes trapezoidal pushing block elasticity of compression return unit to cause trapezoidal push away
Block enters in retaining groove, and the fixture block that briquetting is provided with engages with the neck that end cap body is provided with, and ensures that briquetting can be tight
The close groove being expressed on electric smelting saddle type pipe fitting, anti-sliding stop；2) dynamic clamping head and quiet clamping head is provided with two limited blocks, between limited block
Sheathed spring ensures the restoring force of structure, and spring is not easy；3) shape tooth is shaved by first on electric smelting saddle type end cap inwall
With second on electric smelting saddle type pipe fitting shape tooth is shaved to coordinate so that electric smelting saddle type end cap with electric smelting saddle type pipe fitting is even closer is bonded,
Anti- sliding stop and cause gas leakage.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of fixing device of the present invention.
Embodiment
Below in conjunction with the accompanying drawings with embodiment, the invention will be further described.
See Fig. 1 to Fig. 2, a kind of saddle electric smelting end cap, including end cap body 7, bolt positioning hole 4, the end cap body 7
First is additionally provided with inwall and shaves shape tooth 6, fixing device 5 is additionally provided with the end cap body 7；The fixing device 5 includes sealing
Circle, dynamic clamping head and quiet clamping head, briquetting, trapezoidal pushing block, retaining groove, the sealing ring are arranged in end cap body 7, the sealing ring
Outside is additionally provided with briquetting, and the trapezoidal pushing block is arranged at briquetting both sides, and the trapezoidal pushing block is also associated with dynamic clamping head and quiet clamping head,
The dynamic clamping head and quiet clamping head is arranged in retaining groove, and the retaining groove coordinated with pushing block is additionally provided with the end cap body 7；It is described
Dynamic clamping head and quiet clamping head includes the limited block being arranged in retaining groove and the limited block being arranged on trapezoidal pushing block, described two spacing
