Abstract

The utility model relates to a non-thread angular pipe joint. The non-thread angular pipe joint is mainly characterized in that the non-thread angular pipe joint is composed of right-angle semicircle bending pipes (1, 2) which are in upper and lower halves and are fixedly connected by screws; a semicircle boss (10) is respectively arranged at both ends of the two upper and the lower right-angle semicircle bending pipes (1, 2), and the semicircle bosses (10) are corresponding to each other. A radical sealing ring (94) is respectively arranged on the semicircle bosses (10), and an axial sealing gasket (5) is arranged at the boundary surface of the upper and the lower right-angle semicircle bending pipes. The utility model has advantages that threads do not need to be twisted on connected pipes when vertical pipes are connected; the non-thread angular pipe joint can be rapidly assembled and is convenient in use; the non-thread angular pipe joint does not leak because of reasonable seal; when in installation, the sizes of pipes are convenient to adjust; when in use, the influence of heat expansion and cold contraction can be eliminated, and the non-thread angular pipe joint is safe and reliable to work.

Description

Non-thread angular pipe joint

The utility model relates to the union elbow that a kind of gas-liquid pipeline connects usefulness, particularly relates to a kind of no screw thread union elbow.

The connection of industry or domestic gas, liquid pipeline need be used union elbow, owing on this pipe joint pipe thread is arranged, so the tubulation screw thread also will be twisted in the end of institute's connecting tube.This gives in the construction and makes troubles, and special tool and support to twist the system screw thread, also wants certain operational site.Sometimes because the restriction in piping erection place is installed inconvenient.In addition, the pipe thread connection can be expanded with heat and contract with cold by variation of ambient temperature, joint is produced burst apart, and causes the accident.

The purpose of this utility model is a kind of no screw thread union elbow of design, and two vertical tube do not need connecting tube strand system screw thread during adapter, but quick mounting is easy to use, and can conveniently regulate the pipe range size and eliminate the influence of expanding with heat and contract with cold, and is safe and reliable.

The utility model pipe joint of realization above-mentioned purpose is made up of upper and lower two halves right angle semicircle bend pipe, and the separating surface place of upper and lower right angle semicircle bend pipe is provided with axial gasket.For realizing the firm connection of two halves right angle semicircle bend pipe, the position is corresponding and have an engaging lug of fixing perforation each other respectively four on the upper and lower right angle semicircle bend pipe in the utility model, with screw the right angle semicircle bend pipe of these upper and lower two halves is fixedly fused, and, the semicircle boss that a position correspondence is also respectively arranged in the place, two ends of wherein upper and lower right angle semicircle bend pipe, a radial direction seal ring is respectively arranged on the semicircle boss, realize elbow and connected being tightly connected of straight tube.

Following accompanying drawing has provided embodiment of the present utility model, is described further in conjunction with the accompanying drawings.

Figure 10 a, Figure 10 b are respectively the local enlarged diagram of I among Figure 10, II.

Symbolic representation among Fig. 1-10 is as follows: go up right angle semicircle bend pipe 1, following right angle semicircle bend pipe 2, screw 3, radial direction seal ring 4, axial gasket 5, connected

tube

6,7, engaging lug 8, hole 9, semicircle boss 10, engaging lug 11, tapped hole 12, Baltimore groove 13.The transverse section of radial direction seal ring 4 is

Shape, semicircle boss 10 is pressed in the Baltimore groove 13.The transverse section of axial gasket 5 is

Shape.Radial direction seal ring 4 and axial gasket 5 fuse for rubber die casting.

The utility model is to use like this, an end of waiting to be connected into two pipes that the right angle connects is put radial direction seal ring respectively, then, be placed on down on the right angle semicircle bend pipe 2 and and compress into Baltimore groove 13 semicircle boss 10, to go up right angle semicircle bend pipe 1 again closes up, axial gasket 5 is placed on the separating surface place, passes hole 9 on the engaging lug 8 with screw 3 and is screwed into after screw 12 on the engaging lug 11 tightens screw 3, promptly finishes.

The utility model has the advantages that, connect two vertical tube do not need will be on the connected tube strand screw thread processed, can Fast Installation, easy to use. Because sealing is not rationally leaked, and, be convenient to when mounted adjust the pipe size, can eliminate the impact of expanding with heat and contract with cold during use, safe and reliable.
