Description
Technical field
Reduced pipe technical field is the utility model is related to, more particularly to a kind of straight-through reduced pipe.
Background technology
Straight-through concentric reducer is called commonly using straight-through reduced pipe, straight-through reduced pipe in pipeline connection, its tube body is along microcephaly
The direction of stub end is directed toward at end, the gradual increase of the inside and outside equal uniformity in footpath, and along small head end or stub end axis direction, greatly
Head end and small head end are concentric, have a slope surface between the stub end of reduced pipe and small head end due to leading directly to, when medium is by major part one end
When flowing to microcephaly one end, the tube wall part impact that medium gradually changes tube body caliber is very big, and inside pipe wall is even perforated by cavitation erosion,
Therefore some straight-through reduced pipe coated with buffer layer on the inner wall of reducing pipeline section of in the market, reduce the stream by fluid herein
Speed, thereby protects inside pipe wall, though this structure can protect inside pipe wall, cushion be connected with inside pipe wall it is insecure, in fluid
Washing away under gradually come off, cause pollution to fluid or even block, meanwhile, the cushion of this structure is not easy to replace, once
When going to pot or safeguard replacement, workload is very big.
Utility model content
The utility model is above-mentioned in order to overcome the shortcomings of, there is provided a kind of straight-through reduced pipe, including big straight pipe and small straight
Pipeline section, is equipped with reducing pipeline section, the reducing pipeline section and small straight pipe are structure as a whole, described between big straight pipe and small straight pipe
Big straight pipe is equipped with concave step at the port outer rim of one end of reducing pipeline section, and step is equipped with external screw thread, reducer pipe
The internal thread coordinated with external screw thread is equipped with the corresponding external screw thread of section, reducing pipeline section and big straight pipe are connected through a screw thread, described
Baffle ring is equipped with the inside of rank, side of the baffle ring away from reducing pipeline section is equipped with rubber ring, and the reducing pipe segment inner surface is equipped with ceramics
Inner sleeve, the inner surface of ceramic inner sleeve is frustum cone structure, and the bottom surface of ceramic inner sleeve is bonded with baffle ring, ceramic inner sleeve it is interior
The scope of the included angle A of surface busbar and axis is 5-30 degree, and the angle of included angle A is smaller, and inside pipe wall is gentler, the stream of buffer fluid
Effect is better.Preferably, the big straight pipe and baffle ring are structure as a whole.Preferably, the cross section of the rubber ring is
Central angle is 90 degree of sector.Preferably, the inner ring of the rubber ring is facing to inside big straight pipe, the outer ring face of rubber ring
The inner surface of big straight pipe is bonded with bottom surface, the rubber ring of this structure, which is met to the side of fluid, is the arcwall face of inner ring, and has
Certain elasticity, aids in the flow velocity of buffer fluid.Preferably, the included angle A is 10 degree.
The beneficial effects of the utility model are：The utility model is simple in structure, and ceramic inner sleeve and rubber ring can play very
The effect of good buffer fluid, ceramic inner sleeve is stuck between baffle ring and reducing pipeline section, therefore is connected firmly tightly with reducing pipeline section
It is close, and ceramic inner sleeve is wear-resisting, corrosion-resistant, service life length, it is difficult to come off, when replacement unscrew external screw thread on big straight pipe and
Internal thread on reducing pipeline section can remove ceramic inner sleeve, and it is convenient to replace, and reduces workload.
