Abstract
The utility model pertains to the technology field of pipe connection and in particular to a ferrule metal pipe joint. The joint is composed of a shell, a conical seal ring, a butterfly ring and a nut. The taper of the conical seal ring matches with a conical inclined plane at the end of the shell; the external diameter of the butterfly ring matches with steps at the bottom of the nut. While in installation, telescope the nut, the conical seal ring and the butterfly ring on the pipe, insert the pipe into the joint and wind up the nut and the shell. The utility model has good sealing performance, long service life and firm and stable connection between the joint and the pipe.
Description
Technical field
The utility model metal conduit interconnection technique field is specifically related to a kind of FERRULETYPE metallic pipe coupling.
Technical background
Pipe coupling in the market is various, and thread type butt joint, FERRULETYPE joint, nonmetal joint etc. are arranged.1, the thread type joint is had relatively high expectations to the wall thickness of material, therefore causes user cost too high, and trouble is installed, in case the screw thread preparation is bad, just occurs seepage easily.2, the FERRULETYPE joint adopts the annular seal circle, and is nonmetallic material, and its fixed performance is poor, and the time is long, and nonmetal seal ring easily takes place aging, also can cause seepage.3, nonmetal joint adopts adhering method to connect, and is unable to undergo vibrations, expanded with heat and contract with cold to influence its withstand voltage properties also poor, and the sticky object of abutting edge is apt to deteriorate, aging, also seepage can take place.All there is short defective in working life in product in the market in sum.
Summary of the invention
The purpose of this utility model be to design a kind of be difficult for aging, can seepage, thereby the FERRULETYPE metallic pipe coupling of long service life.
The FERRULETYPE metallic pipe coupling of the utility model design, its structure as shown in Figure 1.It is constituted by housing 1, cone-shaped sealing ring 3, butterfly ring 4 and nut 2, wherein, the port part of housing 1 outside is an outside thread, and inwall is a tapered slope 5, nut 2 inwalls are and the internal thread of the outside thread of housing 1 port part coupling that one step 6 is arranged at the internal thread bottom; Cone-shaped sealing ring 3 and butterfly ring 4 are between housing 1 and nut 2, and the tapering of the outer side surface of this cone-shaped sealing ring is consistent with the angle on the inboard inclined-plane of housing 1 port part, mate the internal diameter coupling of the external diameter of butterfly ring 4 and nut 2 bottom stage 6 mutually; Cone-shaped sealing ring 3 all can adopt nonferrous materials with butterfly ring 4.Use cone-shaped sealing ring, after joint was tightened, tube contacts was tight, improved sealability.Use the butterfly circle can make pipeline and joint connecting tube, make the joint firm by compressing the generation Baltimore groove, stable.
Metallic pipe coupling of the present utility model is compared with pipe joint in the market has the relatively more outstanding advantage in following two aspects:
1, simple installation: need only be during installation with nut, conical seal ring, dish-shaped ring, be enclosed within on the specification pipeline corresponding with joint, then pipeline is inserted on housing, to screw in the joint and with nut and get final product, need not be in the installation process by any equipment and technology, thus certain manpower and materials saved.
2, good quality: adopt nonferrous materials to make tapered collar and butterfly ring, have good sealing property and stationarity and high pressure resistant, thereby make the possibility that seepage takes place very little, prolonged the working life of product.
Description of drawings
Fig. 1 is the utility model structural diagrams.
Number in the figure: 1 is housing, and 2 is nut, and 3 is cone-shaped sealing ring, and 4 is the butterfly ring, and 5 is the tapered slope of shell ends oral area, and 6 is the step of nut bottom.
Embodiment
According to shown in Figure 1, according to the diameter of connecting tube, the pipe coupling of design different model.Wherein, in the housing 1, the tapered slope 5 of port part, its angle of inclination is 20 °-40 °.Cone-shaped sealing ring 3 taperings are consistent with the inclination angle size of tapered slope 5, and its ring wall internal diameter is consistent with the internal diameter of housing, and its height is consistent with the height of taper lap 5, is generally 3-4.5mm; The internal thread coupling of the external diameter of butterfly ring 4 and nut 2 highly is 2.5-3.5mm.During installation,, then pipeline is inserted in the joint, nut 2 is screwed on housing get final product as long as it is corresponding with joint on pipeline that nut 2, cone-shaped sealing ring 3, butterfly ring 4 are enclosed within specification.Awl table seal ring 3 and butterfly ring 4 can adopt nonferrous materials.
After pipeline and joint install, the pipeline that inserts in the connection port is outwards stretched to a certain degree, and test result proves, joint pressurized place ne-leakage, and the seal ring pulling force characteristic has improved 10%, and this function has remedied in the market that in a single day some pipelines have micro-stretching will produce the defective of seepage.
