Abstract
The utility model discloses a rapid jointing device for threadless pipelines, which is suitable for connection and seal of the threadless pipeline whose phi is less than 65 mm. The utility model changes the traditional connection that the connected pipelines must be machined with the thread. The device is composed of a pressure bearing body, a fastening nut and a sealing fastening sleeve. The medium of the pipeline is the water or the coal gas, the medium temperature is-30DEG C to 150DEG C, and the operating pressure is 2.5MPa. Because the connected pipelines need not be machined with the thread, the utility model can realize rapid connection, quickening the construction progress, lessening the labour intensity, shortening the construction period. The device is suitable for the butt joint, the movable joint, the elbow joint, the three-way joint, the four-way joint of the pipelines, the joint of the running water tap or the joint of the heating end cover.
Description
The invention belongs to a kind of technological improvement of assembling pipe joint, be applicable to the connection and the sealing of the following threaded tube of φ 65mm, water tap, warm vapour end cap or valve.
At present, both at home and abroad in pipeline construction, being connected between the tube and tube, between pipe and the tap, between pipe and the valve, for medium and small caliber, must process screw thread in the end of connected pipe, again with asbestos rope, the rope made of hemp, paint and the pipeline connecting fitting that has an internal thread is connected and seals.This structure, speed is slow, and fitting operation labor intensity is big, maintenance is also not quite convenient.
The objective of the invention is to provide a kind of improved pipeline Quick Connect Kit, it not only need not give on pipeline and process screw thread earlier, and easy and simple to handle, and it is laborsaving to economize merit.
Invention is achieved in that in the connected pipe outside, and tapped pressure-bearing body is housed, and the sealing adapter sleeve is housed between pressure-bearing body and the pipeline, and an end of pressure-bearing body has individual crossette, is used to prevent to seal adapter sleeve and moves axially.In the pipeline outside fastening nut that is threaded with the pressure-bearing body is arranged, it compresses the sealing adapter sleeve, makes its distortion, thereby compresses the effect that pipeline outer wall reaches connection and closed conduit.
Because the present invention not be used in machining screw on the pipeline, thus have processing ease, economize merit laborsaving, easy to maintenance, be easy to promote, can realize the quick connection characteristics in screw-thread-free pipe road.
Below in conjunction with accompanying drawing invention being done one describes.
Fig. 1 is the sectional drawing of the quick screw-thread-free pipe road connection set of proposition according to the present invention.
During operation, pressure-bearing body (2) need only be inserted on connected pipe (4), (5), will seal adapter sleeve (3) again and be contained in the pressure-bearing body (2), at last fastening nut (1) is screwed in the pressure-bearing body (2), till sealing adapter sleeve (3) is compressed.Sealing adapter sleeve (3) is a nonmetal hollow Cylinder, make with ethylene propylene rubber or teflon, when being subjected to the axial pressure of fastening nut (1), produce compressive strain, thereby generation radial force, this power tightly is pressed on coupled pipeline (4), (5) sealing adapter sleeve (3), has played the effect of quick connection and sealing.The present invention is applicable to the caliber that φ 65mm is following, and medium is water or coal gas, medium temperature-30 ℃-150 ℃, working pressure 2.5MPa.The wall thickness of sealing adapter sleeve (3) is 3mm to 8mm, is advisable with 5mm; Be 15mm to 50mm highly, be advisable with 30mm; With the gap of connected pipe (4), (5) external diameter be 0.1mm to 0.5mm.Butt joint, movable joint, the elbow that the present invention is used for the screw-thread-free pipe road connect, three connect, four-way connects, water tap connects, the heating installation end cap connects or valve connects.
Claims (4)
1, a kind of quick screw-thread-free pipe road connection set, it is made up of fastening nut (1), pressure-bearing body (2), it is characterized in that: between pressure-bearing body (2) and connected pipe (4), (5) sealing adapter sleeve (3) is housed.
2, device according to claim 1, it is characterized in that sealing adapter sleeve (3) is a nonmetal hollow Cylinder.
3,, it is characterized in that sealing adapter sleeve (3) and make with ethylene propylene rubber or teflon according to claim 1,2 described devices.
4, according to the described device of claim 1, the thickness that it is characterized in that sealing adapter sleeve (3) is 3mm to 8mm, highly is 15mm to 50mm.
