Abstract

The invention discloses an elbow for various pipelines. The exterior angle of the through portion of semi-circumferences on the outer sides of two through straight tubes is in arc transition, the interior angle of the through portion of the inner sides of the two straight tubes is 90 degrees, an axial notch is formed in the center of each of the semi-circumferences of the inner sides of the two straight tubes, the inner ends of the two notches are communicated, the outer ends of the two notches are arranged at tube openings of the corresponding straight tubes, each end of each notch is not exposed out of the circumferential end of the inner side of the corresponding straight tube, and accordingly, an open or sealed straight channel between the tube openings of the two straight tubes is formed. The invention further discloses another elbow for various pipelines. The two straight tubes are communicated through a small-radian bent tube. The open or sealed straight channel is formed between the two straight tubes, so that the distance of the route that an object passes through the straight tubes is reduced, obstacles at the interior angle of the straight tubes are avoided, and the object can pass through the straight tubes conveniently. The bending radian of the elbow is lowered, liquid can pass more smoothly, and the pipelines are prevented from being blocked.

Description

Multiple types channel bend

(1) technical field:

The present invention relates to field construction equipment, be specially one kind of multiple class channel bends.

(2) background technique:

I has formerly applied for " multiple types channel bend " (patent of invention number: 201310347900.9) by name to State Patent Office; because product and composition are comprehensively and in electrically and in the construction of automatic system wiring work of industry and civil building, the normal object adopting the mode laying spool to reach protection cable, facilitate maintaining cables, keep building wall neat and artistic.

In Specific construction, such as cable need be arranged in each section of spool successively, for the turning of wiring, need adopt the connection that 90 ° of elbows realize between two sections of straight tubes, and cable threading is the most unfeasible in construction in 90 ° of elbows; Existing 90 ° of elbows are passed through mutually by two straight vertical siphunculus to form, in threading process, cable in pipe is often blocked by ° bent angle of 90 in pipe, be difficult to light turnover, particularly thick line cable is to small diameter winding pipe threading, need are manually constantly bending, and cable could a section be walked by cable, and causing work progress loaded down with trivial details, is the major reason affecting construction period progress.

Relate to the various pipes elbow of turning in addition, as carried the channel bend of gas or liquid, for convenience of the making of mould, many employings 90 ° of bend pipes, because its crooked radian is comparatively large, all there is obstruction obstacle in various degree, as sewerage is often stopped up by the grease accumulated.

(3) summary of the invention:

For the deficiency that existing elbow exists, the object of this invention is to provide a kind of multiple types channel bend effectively can avoided bent angle and hinder.

A kind of technological scheme of multiple types channel bend of the present invention, comprise the orthogonal two sections of straight tubes of center line, the center of described two sections of straight tube mouths of pipe is equal to the distance of intersection point, difference is that described two sections of straight tubes vertically pass through mutually, outside two sections of straight tubes, semicircle phase passes through the exterior angle arc transition at place, inside two sections of straight tubes, the interior angle at the semicircle phase place of passing through is 90 °, inside two sections of straight tubes, semi-circumference offers axial notch respectively between two parties, the inner of described two notches communicates, the outer end of two notches terminates in the mouth of pipe of corresponding straight tube, every side of two notches is no more than the inside circumference side of corresponding straight tube, thus form the put-through channel opened wide between two sections of straight tube mouths of pipe, described put-through channel makes the path between two sections of straight tube mouths of pipe no longer become more smooth and easy through the inner side bent angle of straight tube.

Conventionally, described put-through channel plate body surrounds closed channel, and can be used for liquid conducting pipes installation, meets taking advantage of a situation of fluid and is unlikely to produce the Laws of Mechanics circling round and flow.

Described plate body comprises header board and both sides side plate, and the upper/lower terminal of described header board is connected to the outer end of two notches, and described side plate is the side of mouth of connecting trough and the side of header board respectively.

The another kind of technological scheme of multiple types channel bend of the present invention, comprise the orthogonal two sections of straight tubes of center line, the center of described two sections of straight tube mouths of pipe is equal to the distance of intersection point, difference is communicated with by bend pipe between described two sections of straight tubes, for effectively reducing bending amplitude, the central angle of described bend pipe is less than 90 °.

As further preferred, the central angle of described bend pipe is less than 60 °.

For avoiding bending amplitude too small and line-like pipe, the central angle of described bend pipe should be greater than 20 °.

For being easy to die sinking, the nozzle diameter of described two sections of straight tubes is greater than the nozzle diameter of bend pipe.

Connect for ease of installing, the length of described two sections of straight tubes is chosen as 1/4 ~ 3/4 of its nozzle diameter.

Advantage of the present invention:

1, multiple types channel bend of the present invention is by the mode of fluting, defines open or enclosed put-through channel, shortens the path of object by straight tube, avoid the obstacle at straight tube interior angle place, facilitate object walking in straight tube between two straight section pipes.

2, multiple types channel bend of the present invention adopts the bend pipe of 20 ° ~ 60 ° of central angles to connect two sections of straight tubes, effectively reduces crooked radian, is more conducive to cable and walks the unimpeded mistake with liquid stream, prevent line clogging.
