Abstract

The utility model relates to a hard-seal universal four-way pipe joint which consists of a pipe joint main body, branch pipe joints and connection caps. According to the hard-seal universal four-way pipe joint, the floating type universal rotary adjustment for the branch pipe joints is realized through a structure that an inner conical face of the pipe joint main body and convex spherical faces of the branch pipe joints are in sealed connection and a structure that the convex spherical faces of the branch pipe joints and concave spherical faces of the connection caps are coupled, so that the universal adjustment for branch pipes in branch pipe joint directions can be achieved through the hard-seal universal four-way pipe joint after the branch pipes are subjected to position deviation. A beneficial effect is brought for project pipe manifold construction. The split-assembled universal four-way pipe joint has the remarkable advantages of novel design, reasonable structure, strong applicability, and convenience, labor saving and time saving in mounting.

Description

The universal union cross of a kind of hard sealing

Technical field

The utility model relates to Placement and the Universal rotary structure of a kind of union cross, particularly a kind of union cross, belongs to Machine Design manufacturing technology field.

Background technique

Union cross is pipe joint, connects the connecting part of two or three laterals for main pipeline.The structural type of tradition union cross is more, but the current known no matter any union cross of people, it is all fixing and nonadjustable that its pipe connects direction.Such pipe joint is quite high with respect to the status requirement of main pipeline for branch pipe(tube) in use and installation process, if there is the angle upper deviation in branch pipe(tube) with respect to main pipeline, adjusting is quite to bother, and some treats that different occasion even causes installing connection and can't realize.Therefore design a kind of can be in certain scope the direction of universal adjustment union cross, in the situation that branch pipe(tube) off-design angle realizes that the union cross effectively connected is necessary smoothly.

Summary of the invention

Can not adjust brought installation drawback for the pipe that overcomes traditional union cross connects direction, the utility model provides a kind of hard sealing universal union cross, in the situation that there is augular offset in branch pipe(tube) with respect to main pipeline, realizes smoothly effectively connecting.

The utility model realizes that the technological scheme of above-mentioned purpose is: the universal union cross of a kind of hard sealing, by pipe joint body, branch pipe connection, attachment cap, formed, be provided with the cross four-way in described pipe joint body, and be equipped with screw thread on the outer dia of every passway, it is characterized in that the orifice end of described pipe joint body inner cross shape four-way is equipped with an inner conical surface; Described branch pipe connection is four, is provided with port hole in it, and an end of port hole is provided with Internal Pipe Thread, and the outside one end is provided with the protruding sphere of two different diameters, and two spheres are concentric; Described attachment cap is four, and the one end is provided with internal thread, and the other end aperture is provided with recessed sphere; The other end of described four branch pipe connections is respectively through the attachment cap matched with it, and four internal threads on attachment cap are screwed respectively on the screw thread be provided with in pipe joint body inner cross shape four-way outside, screw attachment cap and can make a protruding sphere on branch pipe connection and the inner conical surface gluing, sealing in pipe joint body inner cross shape four-way aperture, another the protruding sphere on branch pipe connection and the recessed sphere phase coupling of attachment cap one stomidium mouth.

The structure that the utility model is tightly connected mutually by the inner conical surface on pipe joint body and protruding sphere on branch pipe connection, and by the structure of the recessed sphere phase coupling on the protruding sphere on branch pipe connection and attachment cap, realize that the floating type Universal rotary of branch pipe connection is adjustable, solve branch pipe(tube) after the occurrence positions deviation, can realize the universal adjustment on the branch pipe connection direction by the utility model.To the engineering manifold, construction has brought beneficial effect.

The utlity model has novel in design, rational in infrastructure, strong adaptability, easy for installation, saving of labor, timesaving remarkable advantage.

The accompanying drawing explanation

Fig. 1 is main sectional structure schematic diagram of the present utility model;

Fig. 2 is left view of the present utility model;

Fig. 3 is the position view after the utility model branch pipe connection direction is adjusted.

In Fig. 1,2,3: 1 pipe joint body, 101 recessed spheres, 2 attachment caps, 201 recessed spheres, 3 branch pipe connections, 301 protruding spheres, 302 protruding spheres.

Embodiment

As shown in accompanying

drawing

1,2, be provided with the cross four-way in pipe joint body 1, the orifice end of four-way is equipped with inner conical surface, and is equipped with screw thread on the outer dia of every passway; Branch pipe connection 3 is four, is provided with port hole in it, and an end of port hole is provided with Internal Pipe Thread, and the outside one end is provided with the

protruding sphere

301 and 302 of two different diameters, and two

spheres

301 and 302 are concentric; Attachment cap 2 is four, and the one end is provided with internal thread, and the other end aperture is provided with recessed sphere 201; The other end of four branch pipe connections 3 is respectively through the attachment cap 2 matched with it, and four internal threads on attachment cap 2 are screwed respectively on the screw thread be provided with in pipe joint body 1 inner cross shape four-way outside, screw the recessed sphere 201 phase couplings that attachment cap 2 can make a protruding sphere 301 on branch pipe connection 3 and inner conical surface 101 gluing, sealings in pipe joint body 1 inner cross shape four-way aperture, another the protruding sphere 302 on branch pipe connection 3 and attachment cap 2 one stomidium mouths.

As shown in Figure 3, owing to adopting being sealed and matched of inner conical surface 101 and protruding sphere 301 between the pipe joint body 1 in the utility model and branch pipe connection 3, therefore after branch pipe connection 3 rotates to an angle, the sealability between itself and pipe joint body 1 is constant; Owing to adopting the coupling between protruding sphere 302 and recessed sphere 201 to compress between the branch pipe connection 3 in the utility model and attachment cap, therefore, after branch pipe connection 3 rotates to an angle, the compacted form between attachment cap 2 and branch pipe connection 3 is constant.Realized that four branch pipe connections 3 are adjustable with respect to the setting angle between pipe joint body 1.
