Embodiment
See also Fig. 1 to Fig. 7, it has illustrated the non-return device for flow regulation that the first embodiment of the present invention provided.
As shown in Figure 1, this non-return device for flow regulation comprises a body 100, a flow adjusting element 200, a check sheet 300, a loam cake 400 and a Sealing 500, wherein: described Flow-rate adjustment part 200 and described check sheet 300 are divided into described body 100 both sides, described check sheet 300 has the axis 310 of a projection to be fixed in described body 100, described loam cake 400 is covered on the described body 100, and described Sealing 500 is sheathed on outside the described body 100.
As shown in Figure 2, described body 100 has the feed-water end at a connection water source, an and waterexit end, be installed with a supporting base 110 in it, form an attaching slot 111 between described supporting base 110 and the described body 100, its groove face center is provided with a protruding axle 114, one attaching hole 113 is opened in the described protruding axle 114, and a through hole 112 is located at groove face, and the top outer circumferential face of described body 100 is provided with a guide ledges 150, its section area successively decreases from top to bottom, therefore the outer circumferential face of described guide ledges 150 is inclined wall, and like this, this non-return device for flow regulation can more easily be installed in the pipeline, and be not easy directly to be taken out, increased the reliability of installing;
Described Flow-rate adjustment part 200 is an annular elastic element, and it is positioned at described attaching slot 111, and sheathed described protruding axle 114 also is positioned on the described through hole 112; Described check sheet 300 is one can produce elastically-deformable flexible material, it is suitable with described attaching hole 113 that it has an axis 310, therefore, described check sheet 300 can be fixed under the described supporting base 110, described body 100 is provided with a seal boss 130 with the touching position of described check sheet 300, can strengthen the sealing effect of 300 pairs of described through holes 112 of described check sheet; Described loam cake 400 has cross structure 420, current can flow into described body 100 from this cross structure 420, and, the periphery of described loam cake 400 is provided with an annular flange flange 410, and the top of described body 100 is provided with an inverted steps structure 120, when described loam cake 400 was covered on the described body 100, it cooperated by described annular flange flange 410 and described inverted steps structure 120, and it is more firmly firm to make lid establish; Described Sealing 500 is sheathed on described body 100 peripheries, has strengthened the sealability when this non-return device for flow regulation is installed on pipeline.
Described body 100 also is provided with a plurality of protruding 140, Fig. 3, Fig. 4 has illustrated described protruding 140 diverse location, as shown in Figure 3, described protruding 140 are located on the inwall of the described body 100 in the described attaching slot 111, but be not limited thereto, among Fig. 4, described protruding 140 are located on the periphery wall of described protruding axle 114, described protruding 140 will match with described Flow-rate adjustment part 200, when described Flow-rate adjustment part 200 is subjected to hydraulic action and when being crushed, because the effect of projection 140, described Flow-rate adjustment part 200 can not blocked described through hole 112 fully, and the discharge area of just having reduced described through hole 112 reaches the effect of regulating flow.
Fig. 5, Fig. 6 have illustrated the working principle of this non-return device for flow regulation, among Fig. 5, the pressure of feed-water end is less than or equal to the pressure of waterexit end at this moment, therefore described check sheet 300 will be subjected to the effect of waterexit end pressure and the elasticity of self and be close to described seal boss 130, described through hole 112 will be disconnected the waterexit end, the also not water outlet of this non-return device for flow regulation; Among Fig. 6,, make its pressure greater than the waterexit end if increase the pressure of feed-water end, described check sheet 300 will be subjected to the effect of feed-water end pressure and bend downwards, no longer be close to the described seal boss 130 of sealing, therefore described through hole 112 will be connected the waterexit end, the water outlet of this non-return device for flow regulation; Along with the increase of feed-water end current, described Flow-rate adjustment part 200 will produce elastic strain and be crushed, so the discharge area of described through hole 112 of its below reduces, and make the current of flowing through described through hole 112 and flowing out from the waterexit end reduce, thereby regulate the water yield.
Fig. 7 has illustrated the non-return device for flow regulation of the second embodiment of the present invention, itself and first embodiment's structure is roughly the same, difference is, described Flow-rate adjustment part 200 is to be located near the waterexit end, and described check sheet 300 is to be located near feed-water end, promptly be positioned at described Flow-rate adjustment part 200 tops, described body 100 comprises that one is positioned at the supporting base 110 of bottom, described supporting base 110 has an attaching slot 111 with the described Flow-rate adjustment part 200 of attaching, one protruding axle 114 is positioned at the groove face of described attaching slot 111, one through hole 112 also is located on the described groove face, and described Flow-rate adjustment part 200 sheathed described protruding axles 114 also are positioned on the described through hole 112; Described body 100 also comprises a fitting seat 160, described fitting seat 160 has a plurality of spokes 162, affixed described body 100 inwalls of one end of described spoke 162, the other end is pooled to a bit, it is the center of described fitting seat 160, one mounting hole 161 is positioned at this central point, and the axis 310 of described check sheet 300 is fixed in described mounting hole 161 to be fixed under the described fitting seat 160.
Among second embodiment, the working principle of this non-return device for flow regulation is with first embodiment, also be to have utilized hydraulic pressure, promptly, when the pressure of feed-water end is less than or equal to the pressure of waterexit end, described check sheet 300 is subjected to waterexit end pressure and self elastic reaction and is close to and is sealed in described seal boss 130, this moment described through hole 112 with the not water flowing of described feed-water end; When the pressure that continues to increase feed-water end, make its pressure greater than the waterexit end, described check sheet 300 is subjected to the effect of feed-water end pressure and bends downwards, no longer described seal boss 130 is close in sealing, this moment, current entered described attaching slot 111 from feed-water end, flow out the waterexit end from described through hole 112, make the non-return device for flow regulation water outlet, when hydraulic pressure increases to certain value, make described Flow-rate adjustment part 200 that elastic strains take place and when being crushed, the discharge area of described through hole 112 reduces, and therefore the water yield of flowing through also diminishes, and has realized the purpose of Flow-rate adjustment.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process according to this, i.e. the equivalence of doing according to claim of the present invention and description changes and modification, all should still belong in the scope that the present invention contains.
