A kind of flange for valve body combination connection
Technical field
The present invention relates to flange technical field more particularly to a kind of flanges for valve body combination connection.
Background technique
At present in gas or liquid delivery process, the connection between pipeline is typically all that sealing flange is fixedly connected with progress
Conveying, however sealing flange connection often occurs during the connection process and loosens, cause to occur gap between flange to cause to reveal.Have
This loosening is difficult to detect, and as the time of flanged joint is longer, and it is more unreliable to connect, this is defeated to gas or liquid
It send and causes great security risk.
Those skilled in the art are dedicated to solving above-mentioned technological deficiency.
Summary of the invention
In view of the above drawbacks of the prior art, technical purpose of the invention is a kind of method for valve body combination connection
Orchid can also ensure safety while saving resource, to solve above-mentioned background technique to avoid the leakage of gas or liquid
The defect present in.
To realize the above-mentioned technical purpose, the present invention provides a kind of flanges for valve body combination connection, including left flange
With right flange, the left flange and right flange side close to each other open up it is fluted, on the left flange and right flange
From left to right through several threaded holes are offered, the threaded hole internal screw thread connects clamping screw, the left flange and right flange
It is connected by clamping screw, the right end of the right flange is provided with baffle, is provided with sealing between the left flange and right flange
Pipe, the both ends of the seal pipe are plugged in inside grooves, and the inside and outside of the seal pipe is fixedly installed with seal washer, described
Left flange is fixedly connected with the outer wall of right flange by outer screwed pipe.
Further, the right end screw thread outside the left flange and the left end screw thread outside right flange constitute complete screw thread
Lines, its purpose is to facilitate the connection of outer screwed pipe.
Further, the diameter of the external seal washer is equal with the diameter of left and right flange, opens on the seal washer
Equipped with threaded hole through-hole equal in magnitude, the internal diameter of the internal seal washer is equal with the internal diameter of flange.
Further, several threaded holes are in circular arrangement.
Further, the outer screwed pipe is specially cylindrical round tube, is internally provided with screw thread, the outer diameter of the outer screwed pipe
It is equal with the diameter of baffle.
Beneficial effects of the present invention: the present invention opened up by left flange and right flange side close to each other it is fluted,
From left to right through several threaded holes are offered on the left flange and right flange, the threaded hole internal screw thread connects locking screw
Bolt, the left flange are connected with right flange by clamping screw, and the right end of the right flange is provided with baffle, the left flange and
Seal pipe is provided between right flange, the both ends of the seal pipe are plugged in inside grooves, the fixed peace in the inside and outside of seal pipe
Equipped with seal washer, safety can also be ensured while saving resource to avoid the leakage of gas or liquid.
Detailed description of the invention
Fig. 1 is structure of the invention explosive view.
Figure label: 1 left flange, 2 right flanges, 3 grooves, 4 threaded holes, 5 clamping screws, 6 baffles, 7 seal pipes, 8 sealings
Washer, 9 outer screwed pipes.
Specific embodiment
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.
Embodiment:
Please refer to a kind of flange for valve body combination connection shown in FIG. 1, including left flange 1 and right flange 2, the left flange
1 and the side close to each other of right flange 2 open up fluted 3, from left to right through opening on the left flange 1 and right flange 2
Equipped with several threaded holes 4,4 internal screw thread of threaded hole connects clamping screw 5, and the left flange 1 and right flange 2 pass through locking screw
Bolt 5 connects, and the right end of the right flange 2 is provided with baffle 6, is provided with seal pipe 7, institute between the left flange 1 and right flange 2
The both ends for stating seal pipe 7 are plugged in inside groove 3, and the inside and outside of the seal pipe 7 is fixedly installed with seal washer 8, are worth
It is noted that the diameter of the external seal washer 8 is equal with the diameter of left and right flange, the internal diameter of the internal seal washer 8
It is equal with the internal diameter of flange, it is offered on the seal washer 8 and the through-hole equal in magnitude of threaded hole 4, the left flange 1 and right method
The outer wall of orchid 2 is fixedly connected by outer screwed pipe 9, it is notable that right end screw thread and right flange 2 outside the left flange 1
External left end screw thread constitutes complete screw thread lines, and its purpose is to facilitate the connection of outer screwed pipe 9, the seal washer 8
Diameter it is equal with the diameter of left and right flange, offered on the seal washer 8 and the through-hole equal in magnitude of threaded hole 4, be worth note
Meaning, the outer screwed pipe 9 are specially cylindrical round tube, are internally provided with screw thread, the outer diameter and baffle 6 of the outer screwed pipe 9
Diameter it is equal.
When connection, the groove 3 of left flange 1 and right flange is aligned, one end of seal pipe 7 is then inserted in one of method
In blue groove 3, then the groove of another flange 3 is socketed on 7 other end of seal pipe, it then will by clamping screw 5
Left flange 1 and right flange 2 are pressed and are fixed, and outer screwed pipe 9 is finally threadably mounted to the outside of left flange 1 and right flange 2.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
