Background technique
When between with pipe fitting, interconnecting, need to use pipe joint usually.And it is very important to guarantee that jointing between pipe fitting and pipe joint has good sealing property.One of method of using in the existing technology is that the interior edge face of pipe joint one end is arranged to inner conical surface; And on the periphery of the end of pipe fitting to be connected cutting ferrule of welding; A pipe of the outer installation of cutting ferrule nut; Wherein, pipe nut internal surface be provided with the pipe joint periphery on the internal thread that matches of outside thread.To manage nut and pipe joint is tightened, and at this moment, be welded under the effect that being fastened in the pipe nut on the pipe fitting and compress, form sealing surface thereby make between cutting ferrule and the pipe joint in pipe joint.The defective of such method is; Can only form a sealing surface between cutting ferrule and the pipe joint; And the formation of the sealing surface that this is unique receives the influence of numerous factors such as whether accurate the welding position of machining accuracy and cutting ferrule of cutting ferrule itself, and its sealing effect is difficult to be guaranteed.
Summary of the invention
The technical problem that desire of the present invention solves is to provide a kind of pipe fitting that is used for to connect cutting ferrule and method, is that the pipe fitting connection is more simple and convenient, and has better sealing effect.
For solving the problems of the technologies described above, cutting ferrule provided by the invention has following shape and structure:
A kind of cutting ferrule that is used for the pipe fitting connection comprises that integral body is the cutting ferrule body of tubular body, and the first end end face of said cutting ferrule body is provided with wedge angle.
Preferably, said wedge angle evenly is provided with for the circumference along cutting ferrule body end face.
Preferably, the inner conical surface of the male cone (strobilus masculinus) of the wedge angle of first end of said cutting ferrule and pipe joint is suitable.
Preferably, the pipe face of second end of said cutting ferrule body is provided with convexity.
Preferably, said convexity evenly is provided with for the circumference along the cutting ferrule body.
Preferably, the end surface shape of second end of said cutting ferrule body is suitable with the corresponding position shape of pipe nut.
The present invention also provides a kind of method that pipe fitting connects that is used for, and comprises pipe fitting is connected with pipe joint that said pipe fitting is connected with pipe joint may further comprise the steps:
The pipe nut sleeve is loaded on the connecting end of pipe fitting;
Aforementioned arbitrary described cutting ferrule is set in the connecting end of pipe fitting;
Pipe joint is connected with said pipe fitting;
Said pipe joint and said pipe fitting are tightened.
Preferably, described pipe fitting is connected with pipe joint also comprises the step of using frock that the end to be connected of pipe fitting is risen and no longer gets loose to cutting ferrule greatly.
Compared with prior art, use cutting ferrule of the present invention and method, greatly simplified pipe fitting connection work, and effectively improved the sealing effect between pipe fitting and the pipe joint.

Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention is described in detail, but is to be understood that protection scope of the present invention does not receive the restriction of embodiment.
As shown in Figure 1, described cutting ferrule of the present invention comprises that integral body is the cutting ferrule body 1 of tubular body, and first end, 3 end faces of said cutting ferrule body 1 are provided with wedge angle 5.Wherein said wedge angle 5 evenly is provided with for the circumference along cutting ferrule body 1 end face, and the inner conical surface of the male cone (strobilus masculinus) of wedge angle 5 and pipe joint 9 is suitable.The pipe face of second end 2 of said cutting ferrule body 1 is provided with protruding 4.Wherein said protruding 4 for the circumference along cutting ferrule body 1 evenly is provided with, and forms the boss shape, and the end surface shape of second end 2 of cutting ferrule body 1 is suitable with the corresponding position shape of pipe nut 10.
Below will the method for using of this cutting ferrule be elaborated, the purpose of this method for using is pipe fitting as shown in Figure 2 and pipe joint as shown in Figure 3 are coupled together, and guarantees to have good sealing effect.This method for using specifically may further comprise the steps:
1, pipe nut 10 is set in the connecting end 6 of pipe fitting;
2, cutting ferrule body 1 is set in the connecting end 6 of pipe fitting, can also use this moment frock that the connecting end 6 of pipe fitting is risen greatly to cutting ferrule body 1 and no longer get loose.This step can prevent that cutting ferrule from getting loose, the sealing effect that can also strengthen connecting;
3, pipe joint 9 is connected with said pipe fitting, as shown in Figure 4, the seam 7 in the pipe joint 9 cooperatively interacts with the end face of pipe fitting connecting end 6 at this moment, forms primary sealing area 11;
4, pipe joint 9 and said pipe fitting are tightened;
As shown in Figure 5, because the outer surface of pipe joint 9 is provided with outer nut, the internal surface of pipe nut 10 is provided with inner nut, can be connected through screw thread each other between pipe joint 9 and the said pipe joint 9.When swivelling pipe nut 10, cutting ferrule body 1 moves to pipe joint 9 under the promotion of pipe nut 10, compresses until first end 3 and the pipe joint 9 of cutting ferrule body 1, and second end 2 of cutting ferrule body 1 compresses with pipe nut 10.Because the end surface shape of second end 2 of cutting ferrule body 1 is suitable with the corresponding position shape of pipe nut 10, form secondary sealing area 12 between cutting ferrule body 1 and the pipe nut 10.When continuing to screw pipe nut 10, cutting ferrule body 1 continues to compress to the inner conical surface of pipe joint 9, and the wedge angle 5 until cutting ferrule body 1 first end 3 places deforms.Because the male cone (strobilus masculinus) of said wedge angle 5 and the inner conical surface of pipe joint 9 are suitable, the inner conical surface of wedge angle 5 conical surfaces and pipe joint 9 forms the 3rd sealing surface 13.
Compared with prior art because this cutting ferrule be free state in use, make between pipe fitting and the pipe joint be connected more convenient simply, and make the primary sealing area that can fully form good seal between connection end face and the pipe joint of pipe fitting.Simultaneously, use this cutting ferrule can make between pipe fitting and the pipe joint and form multi-layer sealed, farthest guaranteed sealing effect.
More than disclosedly be merely a specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
