Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further illustrated.
As shown in the figure, the utility model provides a kind of SEALING FITTING 5 connecting Bamboo-shaped prestressed flat mouth plastics pipe racks sealing gasket outlet pipe, and described SEALING FITTING 5 is docked by half flat mouthful of pipe 1 and the 2nd half flat mouthful of pipe 4 to be bonded SEALING FITTING 5.
As shown in Figure 1 and Figure 2, the described 1st half flat mouthful of pipe 1 outer rim protrudes the outlet pipe 1b being provided with its half flat mouthful of tube wall through.Outlet pipe 1b endoporus is tapped hole, is convenient to connect outside pipeline and is used as outlet pipe use.Outlet pipe 1b is arranged in the middle part of half flat mouthful of pipe 1 outer rim, and the through hole of outlet pipe 1b connects the gap between two Bamboo-shaped prestressed flat mouth plastic tube 3 ends at SEALING FITTING 5 two ends.
There is symmetrical spaced two first groove 1a and the two second largest groove 4a of structure same position respectively at the described inner ring of half flat mouthful of pipe 1 and the inner ring of the 2nd half flat mouthful of pipe 4, be respectively arranged with an a first sealing gasket groove 1c and second sealing gasket groove 4b in the both sides of the both sides of each first groove 1a and each second largest groove 4a.
Described two first groove 1a and two second largest groove 4a are wrapped in the outer rim of the first large flat mouth muscle 3a in Bamboo-shaped prestressed flat mouth plastic tube 3 end that SEALING FITTING 5 two ends are connected respectively respectively.
The little straight tube 3b position of all first with the described Bamboo-shaped prestressed flat mouth plastic tube 3 end large flat mouth muscle 3a both sides of the described first sealing gasket groove 1c on half flat mouthful of pipe 1 inner ring and the described second sealing gasket groove 4b on the 2nd half flat mouthful of pipe 4 inner ring is corresponding.
In a described first sealing gasket groove 1c and second sealing gasket groove 4b, sealing gasket 2 is housed respectively.
The mating face of the described 1st half flat mouthful of pipe 1 and the 2nd half flat mouthful of pipe 4 docking is flanged surface 1e, and this flanged surface 1e axially protrudes to respective outer rim the mating face formed by the mating face of half flat mouthful of pipe 1 and the 2nd half flat mouthful of pipe 4 along SEALING FITTING 5.
To dock on junction plane with the 2nd half flat mouthful of pipe 4 at half flat mouthful of pipe 1 and be respectively arranged with the first transverse sealing connecting groove 1d being communicated with multiple first its end of sealing gasket groove 1c and the second transverse sealing connecting groove 4d being communicated with multiple second its end of sealing gasket groove 4b.
Described sealing gasket 2 comprises the longitudinal sealing pad 2a of multiple half flat shape of the mouth as one speaks of vertical seal joint 5 axis and is parallel to SEALING FITTING 5 axially and be positioned at the lateral connection sealing gasket 2b at multiple longitudinal sealing pad 2a two ends; Described multiple longitudinal sealing pad 2a is separately positioned on half flat mouthful of pipe 1 inner ring interior with in multiple second sealing gasket groove 4b with the multiple first sealing gasket groove 1c on the 2nd half flat mouthful of pipe 4 inner ring; Described lateral connection sealing gasket 2b is separately positioned in the first transverse sealing connecting groove 1d that half flat mouthful of pipe 1 and the 2nd half flat mouthful of pipe 4 connect on junction plane and in the second transverse sealing connecting groove 4d.
In particular, as depicted in figs. 1 and 2, the companion flange face 1c of half flat mouthful of pipe 1 and the 2nd half flat mouthful of pipe 4 presses close to, can adopt sealing gluing and is connected, bolt-locking connection or adhesive tape bundle be connected to form a pipe SEALING FITTING 5.
As shown in the figure, two first groove 1a and two the second largest groove 4a that half flat mouthful of pipe 1 inner ring and the 2nd half flat mouthful of pipe 4 inner ring are arranged respectively are used for wrapping up the first large flat mouth muscle 3a in Bamboo-shaped prestressed flat mouth plastic tube 3 end.
Have in the second sealing gasket groove 4b in the first sealing gasket groove 1c of each first groove 1a left and right sides and in each second largest groove 4a left and right sides and be all provided with flat shape of the mouth as one speaks sealing gasket 2, flat shape of the mouth as one speaks sealing gasket 2 is connected as a single entity by multiple longitudinal sealing pad 2a and two lateral connection sealing gasket 2b to be put into respectively in the first sealing gasket groove 1c and the second sealing gasket groove 4b.The Thickness Ratio first sealing gasket groove 1c of sealing gasket 2 and the degree of depth of the second sealing gasket groove 4b large, after installing, sealing gasket 2 is from the first sealing gasket groove 1c and the projecting inward part of the second sealing gasket groove 4b, because sealing gasket 2 adopts rubber or other elastic material to make, when half flat mouthful of pipe 1 and the 2nd half flat mouthful of pipe 4 combine compression, on the sealing gasket 2 little straight tube 3b being wrapped in first large flat mouth muscle 3a both sides, Bamboo-shaped prestressed flat mouth plastic tube 3 end tightly, thus play seal action.
As shown in Figure 1, in use, the Bamboo-shaped prestressed flat mouth plastic tube 3 connected is needed to align placement by two, then half flat mouthful of pipe 1 and the 2nd half flat mouthful of pipe 4 that sealing gasket 2 is housed are enclosed within the outer rim of Bamboo-shaped prestressed flat mouth plastic tube 3 end respectively, combined closely in one half flat mouthful of pipe 1 and the 2nd half flat mouthful of pipe 4 mating face and be fixed on Bamboo-shaped prestressed flat mouth plastic tube 3 end, under the pressuring action of sealing gasket 2, be easy to realize vacuum seal and connect.
