Description
Technical field
The utility model is related to spheroidal graphite pipe fitting technical field, in particular, is related to a kind of spheroidal graphite pipe fitting flexible mechanical
Formula interface.
Background technology
Nodular cast iron pipe fittings are applied to pipe water, liquid, gas and other fluids for having pressure.Existing spheroidal graphite casting
Iron pipe part uses flexible interface, by interface pattern be divided into mechanically, the class of slide-in type two, mechanical interface pattern is divided into N1 types, x again
Three kinds of type and s types, Slide -in joggle pattern are T-shaped.But existing mechanical interface dismounting is pretty troublesome, and fixed form is simultaneously
It is not firm, over time, or after pipeline axially loaded, sealing effectiveness can be influenceed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of spheroidal graphite pipe fitting flexible mechanical formula interface, the interface
More firm, convenient disassembly, long service life are connected compared to traditional structure.
Technical problem to be solved in the utility model is realized using following technical scheme.
A kind of spheroidal graphite pipe fitting flexible mechanical formula interface, it includes socket and terminal pad, and described socket inserts terminal pad
Inside bellmouth, described socket outside is sequentially provided with pressing plate, waterproof sealing gasket and fastener from the inside to the outside, and described pressing plate is transversal
Face is frustum shape, and sealing ring is fixed with described pressing plate frustum inclined-plane, and described fastener includes baffle plate and fastening post, institute
The fastening post end stated is provided with connection external screw thread, and described terminal pad top is provided with through hole, and described fastening post is logical through through hole
Cross nut to fix, described pressing plate and waterproof sealing gasket being bolted on spheroidal graphite pipe fitting by both sides.
Further, described baffle plate inner side is provided with cushion pad.
Further, height of the height of described pressing plate cross section more than bellmouth.
Further, width of the described waterproof sealing gasket width less than pressing plate.
The cross section of this interface center platen is frustum shape, and frustum inclined-plane is provided with sealing ring, for filling up socket and holding
Gap between mouthful, the waterproof sealing gasket above pressing plate, the sealing of common guarantee interface, pressing plate and waterproof sealing gasket are logical
The baffle plate crossed on fastener is inwardly compressed, and further improves sealing, using nuts and bolt come fixed component, can be caused whole
Body structure is more firm.
Compared with the prior art, the beneficial effects of the utility model are embodied in：
The utility model uses sealing ring and waterproof sealing gasket, with reference to the compression of baffle plate, it is ensured that the sealing of interface, tears open
Only needing to unload screw bolt and nut successively during dress can just complete, and convenient maintenance and install；Pressing plate and annular waterproof sealing
Pad is bolted on spheroidal graphite pipe fitting by both sides, improves the stability of interface unit, can bear bigger axial direction and
Radial load.

Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that utility model is realized are easy to understand, below
With reference to being specifically illustrating, the utility model is expanded on further.
As shown in Figure 1, Figure 2 and Figure 3, a kind of spheroidal graphite pipe fitting flexible mechanical formula interface, it includes 4 disks of socket 1 and connection, inserts
Mouth 1 is inserted inside the bellmouth of terminal pad 4, and the outside of socket 1 is sequentially provided with pressing plate 6, waterproof sealing gasket 2 and fastener 7 from the inside to the outside,
The cross section of pressing plate 6 is frustum shape, and sealing ring 3 is fixed with the frustum inclined-plane of pressing plate 6, and fastener 7 includes baffle plate 71 and fastening 72
Post, fastening post 72 end is provided with connection external screw thread, and the top of terminal pad 4 is provided with through hole, and fastening post 72 is solid by nut through through hole
Fixed, pressing plate 6 and waterproof sealing gasket 2 are fixed on spheroidal graphite pipe fitting by the bolt 9 of both sides, and the inner side of baffle plate 71 is provided with cushion pad 5, presses
The height of the cross section of plate 6 is more than the height of bellmouth, width of the width of waterproof sealing gasket 2 less than pressing plate 6.
, it is necessary to socket 1 is inserted into inside the bellmouth of terminal pad 4 first during installation, the pressure of upper and lower side is sequentially embedded afterwards
Plate 6 and waterproof sealing gasket 2 (inclined-plane is needed towards in bellmouth when pressing plate 6 is installed), are then fixed up and down by two bolts 9 in left and right
The pressing plate 6 and waterproof sealing gasket 2 at end, then install fastener 7, and baffle plate 71 withstands pressing plate 6 and the outside of waterproof sealing gasket 2, passes through
Nut 8 is fixed together post 72 is fastened with the through hole in terminal pad 4, completes to install, during dismounting, can be anti-in the order described above
To operation, the interface structure is firm, good airproof performance, convenient disassembly, long service life.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
