Abstract
The utility model relates to a quick pipe joint. The utility model is formed by that the inner part of a screw hole with internal threads and a conical table at a port is provided with a rubber sealing ring with conical outer side and a gasket, the outer side is a conical opening sleeve, and then a pipe joint hollow bolt with a taper hole is screwed. The utility model utilizes the pressing to the rubber sealing ring of radial pressure and axial component generated by the pipe joint hollow bolt to the opening sleeve to realize tight seal to the port of a steel pipe and the connection of the steel pipes. The utility model has the advantages of reliable connection, rapid and convenient assembly and disassembly and small size. The utility model has various types, such as a through type, a three-way type, a four-way type and a right-angle pipe joint type, and is used for connecting oil, gas and water pipes.
Description
The utility model relates to a kind of quick coupling.
Generally adopt now the pipe joint with taper pipe thread, it is fastening, connect and sealing must be with stuffing such as greasy filth, fibers.Install, dismantle difficulty, labor intensity is big.For overcoming above-mentioned shortcoming, the someone proposes quick and convenient joint, and representational is the pipe joint nut of 86210986.8 " loading and unloading pipeline connector fast " at application number, and the pipe joint of tapered opening cover is installed.It is than high several times of taper pipe thread pipe joint construction efficiency.Owing to adopt and have externally threaded fittings body and the pipe joint nut that tapered opening cover and seal ring are housed, its opening sleeve that connects screw thread, seal ring, fastening steel pipe is axially linking to each other in proper order, so more particularly axial dimension is longer for volume, the tapering of its tapered opening cover is little in addition, pipe joint nut and tapered opening cover produces self-locking in installation process, influences construction quality and speed.
The purpose of this utility model is in order to overcome the deficiency of aforementioned tube joint, provides that a kind of volume is less, loading and unloading are more convenient, the pipe joint of reliable performance.
To achieve these goals, the utility model is taked following structure: it is made of fittings body, rubber seal, packing ring, opening sleeve, pipe joint hollow bolt.Each port of fittings body has internal thread, and the part that the fittings body inner chamber links to each other with internal thread is the taper platform, and its oblique angle is 40 °～60 °; The outside of rubber seal is taper, and its tapering is complementary with the tapering of the taper platform that links to each other with internal thread in the fittings body, and the internal diameter of its external diameter and fittings body internal thread is complementary; The outside of opening sleeve is taper, and its oblique angle is 8 °～12 °; The hole of the threaded end of pipe joint hollow bolt is taper, and its tapering equates with opening sleeve; In the cone shape hole of opening sleeve insertion tube joint hollow bolt, rubber seal is installed on the interior taper platform of fittings body port, the external diameter of packing ring and the external diameter of rubber seal are complementary and press rubber seal, and the pipe joint hollow bolt is screwed into the internal thread of fittings body port and makes the end face of opening sleeve press packing ring.
But fittings body of the present utility model adopts straight coupling body, tee union body, cross fitting body, angle coupling body and other elbow joints body form right angle pipe joint, three-way union, union cross, union elbow and other swan neck joint.
When connecting steel pipe, successively the pipe joint hollow bolt, opening sleeve, packing ring, rubber seal is enclosed within an end of steel pipe, then steel pipe one end is inserted the fittings body inner chamber, rubber seal, packing ring, opening sleeve, the pipe joint hollow bolt is installed in the port of fittings body and tightens the pipe joint hollow bolt, its cone shape hole produces radial component and axial thrust load at opening sleeve, radial component dwindles the opening sleeve internal diameter and is fastenedly connected steel pipe, axial thrust load makes the end face of opening sleeve push to rubber seal by packing ring, produces radial component extruding steel pipe by its outside conical surface and plays seal action.
Because the utility model is taked said structure, the outside for the rubber seal of taper, packing ring, have cone shape hole and in the pipe joint hollow bolt of dress opening sleeve be installed in and carry out the steel pipe connection in the screw of fittings body, reliable, the fastening and favorable sealing property of its connection, volume are less, opening sleeve and pipe joint hollow bolt do not produce self-locking, installation, convenient disassembly, efficiency of construction is higher 10～15 times than common tube joint, need not twist screw thread at steel pipe, can reduce thickness of steel pipe, save steel.
Detailed structure of the present utility model is provided by embodiment and accompanying drawing thereof.
Fig. 1 is a free flow coupling sectional view of the present utility model.
Fig. 2 is the tee union body sectional view of three-way union of the present utility model.
Fig. 3 is the cross fitting body sectional view (having two ports that corresponding element is installed) of union cross of the present utility model.
Fig. 4 is the angle coupling body sectional view (port is installed corresponding element) of union elbow of the present utility model.
With reference to Fig. 1, embodiment one of the present utility model is made of the female straight coupling body 6 of port and the rubber seal 5, packing ring 4, opening sleeve 3, the pipe joint hollow bolt 2 that are installed in straight coupling body 6 ports.Opening sleeve 3 is installed in the cone shape hole of pipe joint hollow bolt 2, cone shape hole equates with the tapering in the opening sleeve outside, its oblique angle is 8 degree～12 degree, and the oblique angle of the taper platform in straight coupling body 6 ports is 40 degree～60 degree, and the tapering and the taper platform in rubber seal 5 outsides are complementary.Tighten pipe joint hollow bolt 2, opening sleeve 3 just shrinks chucking steel pipe 1, and rubber seal 5 is also stressed simultaneously presses steel pipe 1 to radially shrinking, and reaches the effect of sealing.
Embodiment two of the present utility model is three-way unions, and the structure of its tee union body 7 as shown in Figure 2.
Embodiment three of the present utility model is union crosss, the structure of its union cross 8 as shown in Figure 3, wherein two ports are equipped with rubber seal 5, packing ring 4, opening sleeve 3, pipe joint hollow bolt 2.
Embodiment four of the present utility model is union elbows, its union elbow 9 as shown in Figure 4, one of them port is equipped with rubber seal 5, packing ring 4, opening sleeve 3, pipe joint hollow bolt 2 and steel pipe 1.
Embodiment five is swan neck joints, and its fittings body is the elbow joints body.
