Embodiment 1
As shown in Figure 1-Figure 3, the present invention provides a kind of ceramic-lined straight-through reduced pipe, including reducing outer tube 1, ring flange 2, liner
Layer 11, ring flange 2 is located at 1 both ends of outer tube, for connecting adjacent outer tube 1, reducing outer tube 1 include big straight pipe 3, contraction pipeline section 4,
Small straight pipe 5, liner layer 11 are located at 1 inner wall of outer tube, and liner layer 11 includes the transition zone and corundum layer being integrally formed, reducing
Outer tube 1, liner layer 11 are integrally formed, and 3 bottom both ends of big straight pipe are fixedly connected with annular horizontal support plate 6, for fixing
Abrasive rubber, is flexibly connected fixed cover 7 in support plate 6 by screw, and fixed cover 7 is shunk for further fixing abrasive rubber
4 inner wall of pipeline section is equipped with high temperature resistant hexsteel 8, improves the bonding degree of transition zone and 1 tube wall of outer tube, and 8 both ends inner wall of hexsteel is set
There is fixed plate 9, for fixing hexsteel 8, fixed plate 9 is equipped with through-hole 10, shrinks 4 inner wall of pipeline section and is correspondingly provided with through-hole, tortoise plastron
Net 8 is flexibly connected by bolt across corresponding through-hole with pipeline section 4 is shunk.
Liner layer 11 is stretched out in 6 one end of support plate, and 7 one end of fixed cover are held in support plate edge and are screwed, separately
One end is screwed on big straight pipe 3, and the thickness of rubber pad is greater than liner layer, and fluid is made to be stayed along rubber pad arc
Under, to reduce the abrasion of corner's liner layer, it is trapezoidal and court that fixed cover 7, which uses high temperature resistant stainless steel net, 7 mesh of fixed cover,
It is outside macropore, is inward from aperture, in liner layer process, partial molten iron is flowed into along mesh in fixed cover 7 with aluminium oxide,
The smooth corundum layer that one layer thin is formed on fixed cover 7, further increases the rub proofness at rubber pad, and trapezoidal mesh is conducive to solid
Determine corundum layer, fills heat resistant and wear resistant rubber in fixed cover 7, rubber bottom is bonded in by hard rubber in support plate 6, fixed plate
9 are surrounded by groove 12 in through-hole 10, are equipped with seal washer in groove 12, prevent fluid from being flowed out from through-hole 10, improve reducing
Composite pipe tightness, liner layer 11 are corundum ceramic liner.
In the use of the present invention, increase from big straight pipe 3 to the flow velocity of 4 fluid of contraction section, and because there are one for pipeline at this
Fixed angle so that frictional force when fluid flows at this is larger, more serious to the abrasion of liner layer 11, therefore big straight
Arc buffering rubber pad is arranged in 3 bottom of pipeline section, can effectively reduce abrasion of the fluid to reduced pipe corner liner layer, rubber pad bottom
Portion is bonded on fixed support plate 6, and fixed cover 7 is arranged to further fix rubber pad on rubber pad surface, shrinks pipeline section inner wall
Hexsteel 8 is wrapped up, because hexsteel 8 is fixed on reduced pipe 1, is improved by upper setting hexsteel 8, liner layer transition zone when being formed
The bonding degree of transition zone and reduced pipe 1, to improve the firmness that liner layer 11 is connect with reduced pipe 1.
Finally it should be noted that：It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, although
Present invention has been described in detail with reference to the aforementioned embodiments, for those skilled in the art, still can be right
Technical solution recorded in foregoing embodiments is modified or equivalent replacement of some of the technical features.It is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in the protection of the present invention
Within the scope of.
