Compared with the prior art, the novel pipeline connection device not only can realize the 360-degree rotation of the junction of the joint and a valve body in an automobile pipeline system, but also saves the finished automobile assembling space, optimizes the pipeline arrangement quality and reduces the manual assembling cost. The novel pipeline connection device has the characteristics of reasonable design, simple structure, good sealing performance, high pressure resistance, firmness for connection, shock resistance, safety, reliability and the like, and can be used in different environments and under different working conditions.
Description
Technical field
The invention belongs to a kind of novel pipeline coupling arrangement that can 360 ° of rotations; Comprise New Rotary pipe joint in many industries such as lathe, engineering machinery, boats and ships, mould manufacturing, household electrical appliances, medical apparatus, precision type instrument, Aero-Space; A kind of rotary pipe joint that is applied to the automobile pipe-line system especially is provided, and working medium relates to gas and liquid.
Background technique
The numerous areas of pipe connection system in industry born important effect; Automobile pipeline requisite system in the vehicle especially particularly, it has occupied crucial status in chassis braking system and steering system, and wherein the good of pipe joint is the important indicator of the whole vehicle safety of influence; What generally adopt in the present commercial car system at home all is the non-rotating pipe joint; When this pipe joint was connected with frame part, after threaded end was screwed, the nylon tube joining end can't be rotated; Cause the car load connecting pipeline disorderly and unsystematic, influence attractive in appearance; The workman very easily causes because of the space is too small and can't assemble when assembling simultaneously, thereby has strengthened the complexity of workman's assembling, has also increased the assembly space of car load, has increased cost of labor.
Summary of the invention
The object of the present invention is to provide a kind of novel pipeline coupling arrangement that can 360 ° of rotations, utilize O RunddichtringO double sealing structure, guaranteed that the gas tightness of swivel joint has reached technical requirements; Utilize circlip that joint body and swivel head body are connected, guaranteed that like this threaded end of swivel joint is fixing after, the joint body end still can carry out 360 ° of rotations, and does not take place axially to come off.So both guarantee sealing, also realized 360 ° of rotations of joint, and efficiently solved pipeline and connect problem disorderly and unsystematic and that the too small workman in space can't assemble, also reduced overall cost simultaneously.
Technological scheme of the present invention is: a kind of New Rotary pipe joint comprises a joint body, two O RunddichtringOs, a circlip and a swivel joint body.A step hole is arranged in the joint body successively, a groove, a conical surface is arranged at the top, bottom; Circlip is round ring bodies, and an opening slot is arranged in the middle of the ring bodies; The swivel joint body has three annular grooves successively, and wherein the bottom outside wall near the top annular groove is the conical surface.The O RunddichtringO is contained in two annular groove places of the bottom of swivel joint body, and circlip is contained in the annular groove place near end face of swivel joint body; In the step hole with swivel joint body press-in connector body, wherein circlip also gets in the groove in the joint body simultaneously then.The ingenious intrinsic elasticity of utilizing back-up ring of the present invention; When assembling, utilize the conical surface of joint body that circlip is compressed, when circlip gets into the groove of joint body; Circlip relies on elasticity to automatically spring open, and reaches the fixedly purpose of swivel joint body and joint body.Like this, only need during use to get final product the threaded end of swivel joint body is fixing.
Beneficial effect:
The present invention utilizes the double seal of two O type circles to reach the sealing index that pipeline connects; Utilize the intrinsic elasticity of circlip simultaneously; The ingenious difficult problem that press-fits that has solved when assembling; Satisfy the technical requirements of swivel joint, solved existing pipe-line system and arranged rambling situation, reduced the labor intensity the when workman assembles.
