Abstract

The utility model relates to a pipe joint for rapid connection and plugging, which mainly solves the technical problem that the prior pipe fitting adopts a welded choke plug for temporarily plugging to cause complex operation and influence the performance of the pipe fitting due to welding. The technical scheme is as follows: the pipe joint for rapid connection and plugging comprises a pipe port plugging cone and a screw rod with a cone, wherein the two cones have the same conicity; the pipe port plugging cone is sleeved on the screw rod with a cone through an axial hole of the pipe port plugging cone; the front section of the screw rod is provided with an external thread which is rotatably connected and fastened with a nut and a washer; rubber rings used by a plurality of fastening pieces with screw threads are tightly embraced on the cone of the screw rod with a cone and the pipe port plugging cone to keep coaxial; the pipe port plugging cone is fixed on a pipeline port which is needed to be connected and plugged through a lug boss arranged at the bottom of the cone, and the pipeline port is provided with a sealing gasket. The utility model can rapidly connect the pipelines to be connected to pipelines with different calibers on the construction field and can be also used as an end enclosure for on-site pressure test, and the like or communicated pipe fitting.

Description

A kind of quick connection and shutoff pipe joint
Technical field:
The utility model relates to a kind of pipeline and connects and closeouts, be particularly related to a kind of quick connection and shutoff pipe joint, it can be connected to the pipeline that will connect on the different tube diameters pipeline of job site fast, also can be used as end socket or connecting pipe uses such as on-the-spot pressure test simultaneously.
Background technique:
In the construction, need often to make water, pressurized air etc. at the scene, can often run into the inconsistent situation of pipe fitting caliber on on-the-spot pipeline and the tool using, need take long to does homework; In addition, field maintenance at present in that pipeline making part is carried out pressure test, is adopted the interim plug method for blocking of welding, cuts off after the test again, and such way not only needs instrument, work post many (oxygen, acetylene; Welder, pincers worker), and to polishing to the mouth of pipe after the welding, for some alloy steel materials, welding also can influence pipe performance.So, how to address the above problem, improve device maintenance efficient, be exactly the problem that the utility model is attempted solution.
The model utility content:
The purpose of this utility model provides a kind of quick connection and shutoff pipe joint, mainly solves the interim shutoff of existing pipe fitting and adopts the complicated operation of welding plug existence and weld the technical problem that influences the pipe fitting performance.The utility model uses simple tools, just can finish the connection and the pipe plugging of different tube diameters pipeline.
The technical solution of the utility model is: a kind of quick connection and shutoff pipe joint, comprise screw rod and the tube opening shutoff cone of being with cone, the tapering of two cones is identical, tube opening shutoff cone is enclosed within on the screw rod of band cone by its axle center hole, screw rod leading portion band outside thread, tightening nut and pad spin on it, the threaded fastening sheet of multi-disc is closely embraced on the cone and tube opening shutoff cone of the screw rod of being with cone with rubber band, keep coaxial, tube opening shutoff cone is fixed on by the cone base boss to be needed to connect, the pipe end of shutoff, and sealing gasket is set at pipe end.
Cone α angle>150 ° of the screw rod of band cone.
When as quick Connector coupling, the axle center perforate of the screw rod of band cone.
When as the quick blocking pipe joint, the screw rod of band cone is a solid member; When the axle center perforate of screw rod of band cone, the end of the screw rod of the band cone Screw-thread sealing plug that spins, and seal ring is set in the joint.
The beneficial effects of the utility model are: 1): the frictional force that the fastening force of bolt is changed into screw thread; 2): press in the frictional force opposing pipeline by screw thread; 3): realize the quick connection shutoff of different tube diameters pipeline; 4): make simple, easy to use.
Description of drawings:
Fig. 1: be the utility model structural representation
Fig. 2: be the A-A sectional view of Fig. 1
Among the figure: screw rod, 2-tube opening shutoff cone, the threaded fastening sheet of 3-, 4-rubber band, 5-pad, 6-tightening nut, 7-sealing gasket, 8-Screw-thread sealing plug, 9-seal ring, the 10-of 1-band cone needs to connect, the pipeline of shutoff.
Embodiment:
With reference to Fig. 1,2, a kind of quick connection and shutoff pipe joint comprise that the tapering of the screw rod 1 of being with cone and 2, two cones of tube opening shutoff cone is identical, cone α angle>150 of the screw rod of band cone °.Tube opening shutoff cone 2 is enclosed within on the screw rod 1 of band cone by its axle center hole, screw rod leading portion band outside thread, tightening nut 6 and pad 5 spin on it, the threaded fastening sheet 3 usefulness rubber bands 4 of multi-disc are closely embraced on the cone and tube opening shutoff cone of the screw rod of band cone, keep coaxial, tube opening shutoff cone is fixed on by the cone base boss to be needed to connect, pipeline 10 ports of shutoff, and at pipe end sealing gasket 7 is set.
During practical operation, tightening nut 6 is threaded onto on the screw rod 1 of band cone, when tightening nut 6 screws, promoting tube opening shutoff cone 2 moves, threaded fastening sheet 3 parallel sliding on cone, gradually to need to connect, the pipeline of shutoff is 10 close, contact closely, promptly, its effect changes the fastening force of screw thread into the frictional force of threaded fastening sheet 3 screw threads, opposing pipeline medium thrust.Be provided with sealing gasket 7 at tube opening shutoff cone 2 ends with needing to be connected, to stitch between the stifled pipeline 10, improve sealing; When the utility model during as link, directly the be threaded pipeline of tool using of screw rod 1 end of band cone, when model utility during as closeouts, screw rod 1 center of band cone can not perforate, if perforate adopts Screw-thread sealing plug 8 and seal ring 9 to carry out shutoff; 3 numbers of threaded fastening sheet are many, with cone with the inner tube wall area of contact is big, bearing capacity is strong; Be noted that in the installation process earlier with tube opening shutoff cone 2 with need to be connected, to stitch pipeline 10 mouths of pipe that block up and hold out against, screw tightening nut 6 again; The utility model purpose is to improve the field maintenance working efficiency, and therefore, the utility model is good with interim use.
