Abstract
The utility model relates to a pipeline joint matching A and V surfaces of a conical surface, which solves the problems that power and energy are inadequately used and transmitted materials are lost and wasted due to air and liquid leakages caused by high pressure in the pipe and strong mechanical vibration and the like for the joint with a smooth section and the joint is inconvenient to disassemble and the like. The pipeline joint matching the A and V surfaces of the conical surface consists of a forwarding end of the pipeline joint, a succeeding end of the pipeline joint and a joint fixing cap. The utility model is characterized in that the forwarding end of the pipeline joint is provided with a forwarding end of the joint and threads, a V surface of the conical surface and a fixed hole; the succeeding end of the pipeline joint is provided with a succeeding end of the joint and threads and an A surface of the conical surface. The joint fixing cap is provided with a joint cap and internal threads, a small screw hole on the joint cap, a fixed small bolt and a protruding handle. According to the flowing direction of the transmitted materials, the joint succeeding end and the threads at the joint connection along with the flowing direction of the transmitted material protrude in cone-shape and the joint forwarding end and the threads at the joint connection along with the flowing direction of the transmitted material are in internally convex cone-shape. The joint forwarding end and the threads and the joint succeeding end and the threads are buckled by the joint matching the A and V surfaces of the conical surface at the pipeline joint. The design is strong in gas tightness and is convenient, and has low cost.
Description
Technical field:
The design relates to a kind of interface of pipeline, particularly requires strong bubble-tight interface.
Technical background:
Existing common pipe interface all is the waterpipe jointing in smooth cross section; Outer all taps or screw are tied mutually, and the tightness of this interface is not good enough, especially in pipe, produce high pressure; Or under the strong situation of mechanical vibration, this smooth cross section interface just becomes the not good fragile link of tightness in the route of pipe line.Such as: present oil engined water pump turnover water pipe interface is a side grain; Rely on periphery screw thread or many Luo wire connections to close; The changing of the relative positions or situation such as loosening take place and cause the gas leakage of intake pipe interface, the phenomenon that the outlet pipe interface leaks in such interface smooth mating face under the internal-combustion engine judder easily.
This plane longitudinal section interface causes gas leakage easily, leaks under situation such as pipe inner high voltage, mechanical judder.This will waste power source, the loss transport materials.And that many silk nails dismounting is also inconvenient.
Summary of the invention:
The design's purpose be for solved smooth cross section interface under situation such as pipe inner high voltage, mechanical judder, cause gas leakage, leakage and do not make full use of power source, the problems such as waste transport materials and dismounting inconvenience that run off, and provide a kind of conical surface AV to agree with the type pipe joint.
Technological scheme:
The utility model is made up of pipe joint precursor end, the follow-up end of pipe joint, interface locking cap; Pipe joint precursor end is provided with the V face of interface precursor end and screw thread, the conical surface, fixing little screw; The follow-up end of pipe joint is provided with the A face of the follow-up end of interface and screw thread, the conical surface; The interface locking cap is provided with little screw on interface cap and internal thread, the interface cap, fixedly stove bolt, outstanding handle.Flow to according to transmission matter; Follow-up end of interface and the tapered protrusion of screw thread that said interface flows to along transport materials; Said interface longshore current to interface precursor end and screw thread be the indent taper, follow-up end of interface precursor end and screw thread and interface and screw thread adopt conical surface AV to agree with the type interface and are interlockingly connected at said pipe joint place; Interface precursor end and screw thread periphery adopt the design of plus thread silk mouth, and follow-up end of interface and screw thread adopt the design of left-hand thread silk mouth; And have four fixing little screws that diameter is the same and do not penetrate in interface precursor end and screw thread and the equal symmetry of follow-up end of interface and screw thread end; Interface cap and internal thread with interface precursor end and screw thread, the follow-up end of interface and screw thread on fixing little screw corresponding section little screw on four interface caps of the same size is arranged; With four of little screw coupling on the interface cap fixedly stove bolt be connected and fixed interface cap and internal thread, interface precursor end and screw thread, the follow-up end of interface and screw thread; Adopt AV to agree with the type conical surface on interface precursor end and screw thread, the follow-up end of interface and screw thread and closely connect, be installed on the interface precursor end and screw thread, the follow-up end of interface and screw thread that have connected with interface cap and internal thread again; The screw thread of interface cap and internal thread is complementary with the screw thread of interface precursor end and screw thread again, and the outstanding handle of interface cap and interior threaded surface is rotatable, and it is tightened, and twists tightly more, and it is just big more to produce pressure, and said interface air-tightness is strong more.
Beneficial effect: the design can make said interface tightness strong; AV agrees with conical surface ratio more can resist the external pressure that stream material produces in smooth cross section longitudinally, and this project organization is simple, easy to use, technology realizes easily, cost is low.
