Abstract

The utility model relates to a universal straight-through pipe joint which is composed of an inner taper pipe joint, a ball head pipe joint and a connecting cap. Floating universal rotating connection of the ball head pipe joint is achieved by conical surface and spherical surface sealing between the inner taper pipe joint and the ball head pipe joint and coupling of two spherical surfaces between the ball head pipe joint and the connecting cap, and after angular deviation of two right angle pipes occurs, universal adjustment in the ball head pipe joint direction is achieved through the universal straight-through pipe joint. The universal straight-through pipe joint has the advantages of being novel in design, reasonable in structure, high in adaptability, convenient to install, labor-saving and time-saving.

Description

A kind of universal free flow coupling
Technical field
The utility model relates to Placement and the Universal rotary structure of a kind of free flow coupling, particularly a kind of free flow coupling, belongs to Machine Design manufacturing technology field.
Background technique
Free flow coupling is pipe joint, is used for connecting the connecting part of two direct pipings.Existing free flow coupling, it is all fixing and nonadjustable that its pipe connects direction.Such pipe joint use and installation process in require the relative linear position of two pipelines higher, if there is the deviation on straightness accuracy between two rectilinear duct, installing is suitable trouble, some treats that different occasion even causes installing connection and can't realize.Therefore design a kind of direction that can universal adjustment free flow coupling in certain scope, when existing between two rectilinear duct in the situation of several angle, can realize smoothly that the free flow coupling that effectively connects is necessary.
Summary of the invention
Can not adjust for the pipe that overcomes traditional free flow coupling connects direction the installation drawback of bringing, the utility model provides a kind of universal free flow coupling, in the situation that there is augular offset in two rectilinear duct, realizes smoothly effectively connecting.
The utility model realizes that the technological scheme of above-mentioned purpose is: a kind of universal free flow coupling, by endosiphuncular tube connect, the bulb pipe connects, attachment cap forms, the end that described endosiphuncular tube connects is provided with the endosiphuncular tube screw thread, the middle part is provided with the straight hole passage; The end that described bulb pipe connects is provided with the endosiphuncular tube screw thread, and the other end is provided with the straight hole passage, it is characterized in that the other end that described endosiphuncular tube connects is provided with an inner conical surface, and its inner conical surface is connected with the straight hole passage at middle part, and the lateral part of inner conical surface is provided with outside thread; The outside one end that described bulb pipe connects is provided with the protruding sphere of two different diameters, and two spheres are concentric; One end of described attachment cap is provided with internal thread, and the other end aperture is provided with recessed sphere, and should recessed sphere to connect a protruding spherical diameter that is provided with identical with the bulb pipe; The outside the other end that described bulb pipe connects passes attachment cap, and make internal thread rotation on attachment cap be combined in endosiphuncular tube to connect on the outside thread that the lateral part is provided with, screw inner conical surface gluing, sealing that attachment cap can make a protruding sphere that the bulb pipe connects and endosiphuncular tube connect, another protruding sphere that the bulb pipe connects and the recessed sphere phase coupling of attachment cap one stomidium mouth.
The protruding sphere phase Hermetical connecting structure that the inner conical surface that the utility model connects by endosiphuncular tube and bulb pipe connect, and the recessed sphere phase coupling structure on the protruding sphere that connects by the bulb pipe and attachment cap, realize that the bulb pipe connects floating type Universal rotary adjustable, two direct pipings have been solved after the linear position deviation occurs, realize that by the utility model the bulb pipe connects the universal adjustment on direction, construction and installation bring beneficial effect to the engineering manifold.
The utlity model has novel in design, rational in infrastructure, strong adaptability, easy for installation, saving of labor, timesaving remarkable advantage.
Description of drawings
Fig. 1 is main sectional structure schematic diagram of the present utility model;
Fig. 2 is that the utility model bulb pipe connects the position view after direction is adjusted.
In Fig. 1,2: 1 endosiphuncular tube connects, 101 inner conical surfaces, 2 attachment caps, 201 recessed spheres, 3 bulb pipes connect, 301 protruding spheres, 302 protruding spheres.
Embodiment
As shown in Figure 1, endosiphuncular tube connects an end of 1 and is provided with the endosiphuncular tube screw thread, and the middle part is provided with the straight hole passage, and the other end is provided with inner conical surface 101, and inner conical surface 101 is connected with the straight hole passage at middle part, and the lateral part of inner conical surface 101 is provided with outside thread; The bulb pipe connects an end of 3 and is provided with the endosiphuncular tube screw thread, and the other end is provided with the straight hole passage, and the outside one end is provided with the protruding sphere 301 and 302 of two different diameters, and two spheres are concentric; One end of attachment cap 2 is provided with internal thread, and the other end aperture is provided with recessed sphere 201, and recessed sphere 201 and bulb pipe to connect 3 protruding sphere 302 diameters that are provided with identical; The bulb pipe connects 3 the outside the other end and passes attachment cap 2, and make internal thread rotation on attachment cap 2 be combined in endosiphuncular tube to connect on the outside thread that 1 lateral part is provided with, screw attachment cap 2 can make the bulb pipe connect on 3 a protruding sphere 301 with inner conical surface 101 gluing, sealings, bulb pipe connect the recessed sphere 201 phase couplings of another protruding sphere 302 and attachment cap 2 one stomidium mouths on 3.
As shown in Figure 2, due to the endosiphuncular tube in the utility model connect 1 and the bulb pipe connect between 3 and to adopt being sealed and matched of inner conical surface 101 and protruding sphere 301, therefore when the bulb pipe connect 3 rotate to an angle after the sealability that connects between 1 of itself and endosiphuncular tube constant; Due to the bulb pipe in the utility model connect 3 and attachment cap 2 between adopt protruding sphere 302 and coupling between recessed sphere 201 to compress, so when the bulb pipe connect 3 rotate to an angle after, the compacted form that attachment cap 2 and bulb pipe connect between 3 is constant.Realized that the bulb pipe connects 3 setting angles that connect between 1 with respect to endosiphuncular tube adjustable.
