In the present invention, the position relation such as term " upper and lower, upstream side, downstream side " is based on position relationship shown in the drawings, is only the present invention for convenience of description, and can not be interpreted as limitation of the present invention.For example, in Fig. 1 and Fig. 6, upstream side and downstream side are based on upstream side and the downstream side of the fluid flow direction shown in arrow A.
Be installed in the pipeline (not shown) according to the energy-dissipation orifice plate 100 of the embodiment of the present invention, be used for the fluid in pipeline (fluid that the ability of especially wearing and tearing is strong, as the field, mine contain the sand flow body) is carried and carried out energy dissipating.As Fig. 1 and shown in Figure 6, energy-dissipation orifice plate 100 links together by stud 7 and nut 8 with two mounting flanges 5,6 of pipeline, thereby energy-dissipation orifice plate 100 is arranged in pipeline.
In order to increase sealability, be provided with respectively seal ring 9 between energy-dissipation orifice plate 100 and mounting flange 5,6.Energy-dissipation orifice plate 100 is called mounting portion 11 in the part of mounting flange 5,6 center hole peripheries, is used for connecting with mounting flange 5,6.As shown in Fig. 5 and 10, the periphery of the orifice plate main body 1 of energy-dissipation orifice plate 100 reduces along the thickness of part, thereby with mounting flange 5,6 when being connected, the periphery of orifice plate main body 1 can leave little gap along between part and the surface of mounting flange 5,6, and namely mounting portion 11 forms the form of boss, can increase thus the join strength of energy-dissipation orifice plate 100 and mounting flange 5,6.
Therefore in Fig. 1 and Fig. 6, arrow A represents the flow direction of fluid (for example ore pulp) in pipeline, and at Fig. 1, Fig. 5, in Fig. 6 and Figure 10, the upper surface of energy-dissipation orifice plate 100 is called the upstream side surface and lower surface is called downstream side surface.
Below with reference to the energy-dissipation orifice plate 100 of Fig. 1-5 detailed description according to first embodiment of the invention.
As shown in Fig. 1-5, energy-dissipation orifice plate 100 comprises orifice plate main body 1, upper wearing piece 2, and upper periphery wearing piece 3.
Be formed with upstream side groove 13 on the upstream side surface of orifice plate main body 1 and orifice plate main body 1 is formed with the orifice plate main center hole 12 of passing through for ore pulp, upper wearing piece 2 is arranged in upstream side groove 13 and on the inner circle wall in orifice plate main center hole 12.Upper periphery wearing piece 3 is arranged in upstream side groove 13 and is arranged by a plurality of fan-shaped wear-resistant blocks around the periphery of upper wearing piece 2 and forms, and arranges by a plurality of fan-shaped wear-resistant blocks and forms upper periphery wearing pieces 3, makes the processing of upper periphery wearing piece 3 and easier for installation.And because upper periphery wearing piece 3 and upper wearing piece 2 splits form, so energy-dissipation orifice plate 100 is more suitable for being arranged in the larger pipeline of diameter.
As shown in Figure 5, the outer circumferential face of upstream side groove 13 form along from the upstream towards the outward-dipping inclined-plane of the direction in downstream, correspondingly, the outer circumferential face of upper periphery wearing piece 3 forms the inclined-plane adaptive with the outer circumferential face of upstream side groove 13.Here, so-called " adaptive " refer to the outer circumferential face of upper periphery wearing piece 3 form along from the upstream towards the intilted inclined-plane of the direction in downstream, thereby when upper periphery wearing piece 3 is installed on orifice plate main body 1, the inclined-plane of upper periphery wearing piece 3 coordinates with the inclined-plane of upstream side groove 13, has increased the degree that is connected firmly between them.
Orifice plate main body 1 can be made by forged steel, and upper wearing piece 2, upper periphery wearing piece 3 can be made by wear-resistant ceramic based composites (as oxide ceramics, nitride ceramics, carbide ceramics and boride ceramics etc.).Orifice plate main body 1 is made separately by different materials from upper wearing piece 2 and upper periphery wearing piece 3, therefore the manufacture cost of energy-dissipation orifice plate 100 reduces, and after using upper wearing piece 2 of a period of time and 3 wearing and tearing of upper periphery wearing piece, only need to replace with wearing piece 2 and upper periphery wearing piece 3, orifice plate main body 1 can be reused, thereby has further reduced manufacture cost.And then, only replace with the fan-shaped wear-resistant block of a part of peripheral wearing piece 3 according to abrasion condition, further reduced cost.
Upper wearing piece 2 can be bonded on orifice plate main body 1 by Bond (as epoxy adhesive).Simultaneously, on the upstream side surface of orifice plate main body 1, upper wearing piece 2 can be additionally with screw fastening on orifice plate main body 1.Equally, the fan-shaped wear-resistant block of each of upper periphery wearing piece 3 can be bonded on orifice plate main body 1 with Bond, then utilizes screw fastening by the tapped hole 16 that forms on the hole 31 that forms on upper periphery wearing piece 3 and orifice plate main body 1.
As Fig. 1 and shown in Figure 5, installation and carrying for the ease of energy-dissipation orifice plate 100, can be formed with handle hole 17 on the periphery wall of orifice plate main body 1, handle hole 17 for example can be tapped hole, when needs carrying and installation energy-dissipation orifice plate 100, in operating stem (as threaded stem) update hole 17, thereby can carry easily and install energy-dissipation orifice plate 100.
When ore pulp during along arrow A from the upstream flow further downstream, ore pulp clashes into energy-dissipation orifice plate 100 and by energy dissipating, be positioned at the upstream side surface that the lip-deep upper wearing piece 2 of orifice plate main body 1 upstream side and upper periphery wearing piece 3 prevent fluid erosion orifice plate main body 1, and the upper wearing piece 2 on orifice plate main center hole 12 inner circle walls can prevent the inner circle wall in fluid abrasion orifice plate main center hole 12.When upper wearing piece 2 and upper periphery wearing piece 3 may wear to a certain degree, upper wearing piece 2 and upper periphery wearing piece 3 (or wherein a part of fan-shaped wear-resistant block) are changed, need not to change orifice plate main body 1, thereby reduced cost, increased the life-span of energy-dissipation orifice plate 100.

Be understandable that, upstream side groove 13 also can be thought the radial dimension that orifice plate main center hole 12 is positioned at the part of upstream extremity is enlarged and form.
As shown in figs. 1 and 3, the thickness of flange 22 is less than the degree of depth of upstream side groove 13, thus, when being installed to upper wearing piece 2 on orifice plate main body 1, flange 22 does not expose the upstream side surface of orifice plate main body 1, thereby in carrying and installation process, can unexpectedly not cause damage to wearing piece 2.Certainly, the thickness of flange 22 also can equal the degree of depth of upstream side groove 13.
In addition, as Fig. 1 and shown in Figure 5, in order to increase energy-dissipation orifice plate 100 and mounting flange 5,6 fastening forces that connect also can form downstream side groove 14 in the downstream side surface of orifice plate main body 1, thereby when connecting, mounting flange 5,6 only contact the mounting portion 11 on orifice plate main body 1 downstream side surface, as mentioned above, and because the thickness on orifice plate main body 1 periphery edge also reduces, therefore, mounting flange 5,6 can not contact the part in the 11 interior outsides, mounting portion of orifice plate main body 1, thereby can increase fastening force.
As shown in Figure 5, in order to increase the sealability between energy-dissipation orifice plate 100 and mounting flange 5,6, annular seal groove 15a and lower annular seal groove 15b have been formed respectively on the upstream side surface of orifice plate main body 1 and downstream side surface.more specifically, upper annular seal groove 15a and lower annular seal groove 15b are respectively formed on the mounting portion 11 of upstream side surface and downstream side surface, in the example depicted in fig. 5, the cross section of upper annular seal groove 15a and lower annular seal groove 15b is triangle, for example the degree of depth is 1 millimeter or 2 millimeters, but the present invention is not limited to this, thereby in use, if the ore pulp in pipeline is from mounting flange 5, 6 and energy-dissipation orifice plate 100 between the gap ooze out, fluid enters annular seal groove 15a and lower annular seal groove 15b, thereby formation potted line, further increased sealability.
