Abstract
The utility model relates to a quick acting joint for water or gas pipelines. The quick acting joint for water or gas pipelines is characterized in that a rubber cutting sleeve with conical surface outer rounds on both ends is sheathed on the outer diameter of a connected pipe end, and an outer sleeve of the cutting sleeve is provided with a union body. The union body is provided with a nut with same inside and outside threads. The other end of each of the nut and the union body is respectively provided with an inner cone surface corresponding to both ends of the rubber cutting sleeve. When the nut is screwed tightly on the union body, the two inner cone surfaces respectively press the conical surfaces on both ends of the cutting sleeve to cause the cutting sleeve to generate elastic deformation, to clamp a pipe, and to realize the connection and the sealing of a pipe fitting. The utility model overcomes the disadvantage that both ends of a pipe with an old type joint must be turned and tapped, and relieves assembling and disassembling labor intensity.
Description
The utility model is the form of the joint form in a kind of water, the gaspipe line, particularly a kind of rapid pipe joint.
Common water, the joint in the gaspipe line, comprise that socket, union, elbow, threeway, four-way, pipe plug, water (or coal gas) are shown, the fire hose is first-class and connecting of pipeline all adopted straight pipe thread or taper pipe thread, thereby coupled pipe two ends must possess corresponding thread.The thread processing difficulties of this mode on pipe, pipe connects inconvenient during installation with corresponding pipe fitting.Particularly water, coal delivery line construction site is usually unfavorable and operation, installation difficulty is then bigger, leaks easily and maintenance difficult.
The purpose of this utility model is the shortcoming that overcomes above-mentioned old-fashioned pipe joint, provide a kind of at the pipe two ends car, the tapping pipe joint that can connect fast or dismantle not.
The technical solution of the utility model is such: the rubber card cover that the two ends cylindrical is the conical surface is placed in coupled pipe end external diameter, cutting ferrule is set with nut and the union body that an end has identical internal and external threads respectively outward, nut and union body are spun on together, and the other end of nut and union body is respectively equipped with and the corresponding inner conical surface in rubber cutting ferrule two ends.When nut screwed on union body, the inner conical surface of nut and union body compressed the conical surface at cutting ferrule two ends respectively like this, made cutting ferrule produce resiliently deformable, clamping tube, thereby the connection and the sealing of realization pipe fitting.
The utility model has overcome old-fashioned joint pipe two ends must car, tapping, the shortcoming that must rotate pipe during installation can under high pressure prevent to leak, and has alleviated the labor intensity of installation, dismounting greatly.It is simple in structure, and use, easy to maintenance is fit to the quick connection of all kinds of joints in the water gas pipeline.
Describe the novel embodiment of this reality in detail below in conjunction with accompanying drawing.
Half section structural representation when Fig. 1 is the utility model with the footpath.
Half section structural representation when Fig. 2 is the utility model reducing.
As shown in Figure 1, this joint is made up of cutting ferrule 1, connecting body 2, nut 3, and the tapered cutting ferrule 1 in cylindrical two ends is placed on the coupled pipe end external diameter, and internal taper hole that matches with an end conical surface of cutting ferrule 1 and the screw thread that is connected with nut 3 are arranged on the connecting body 2.Nut 3 is spun on connecting body 2, and the other end conical surface of taper hole on it and cutting ferrule 1 matches.When nut 3 screwed with connecting body 2, their taper hole compressed the two ends conical surface of cutting ferrule 1 respectively, made cutting ferrule 1 produce resiliently deformable, was clamped on the coupled tube outer diameter, played sealing and connection.
Fig. 2 is the joint semi-section schematic representation of the utility model when connecting the pipe fitting of different tube diameters.Connected body 2 two ends of adopting among this embodiment are rotary with nut 3 respectively, tighten corresponding cutting ferrule 1 respectively, thereby realize the connection and the sealing of the pipe fitting of different tube diameters.
