Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, the technical solution of the utility model will be described in detail below.Obviously, described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, other embodiments all that those of ordinary skill in the art are obtained on the premise of not making creative work, broadly fall into the scope that this utility model is protected.
As it is shown in figure 1, this utility model provides a kind of check-valves, including entrance 1, outlet 2, first chamber the 3, second chamber 4, pipeline 5, buoyancy aid 6, sealing baffle 7, displacement connector 8；Entrance 1 is connected with the first chamber 3, buoyancy aid 6 and lime set outlet 9 it is provided with below first chamber 3, outlet 2 is connected with the second chamber 4, first chamber 3 is connected by pipeline 5 with the second chamber 4, second chamber 4 and pipeline 5 junction are provided with sealing baffle 7, and sealing baffle 7 is connected by displacement connector 8 with buoyancy aid 6.
Described buoyancy aid 6 is magnetic ball float.The first described chamber 3 is communicated with liquidometer 13, is provided with float 14 in liquidometer 13.Described check-valves also includes buoyancy enlarger, described buoyancy enlarger includes slip transformation actuator 15, electric magnet 18, the connection brush 17 of the outfan of slip transformation actuator 15 connects electric magnet 18, the brush 17 of connecting on slip transformation actuator 15 connects the float 14 inside liquidometer 13 by connector 16, and the lifting of float 14 can be dynamically connected the movement of brush 17 by band.Described connector 16 is insulated connecting piece 16.Described electric magnet 18 is positioned at the lower section of magnetic ball float.It is provided with baffle plate 10 at described entrance 1.Steam it is additionally provided with except mist net 11 in first chamber 3.Described displacement connector 8 and the boundary of first chamber the 3, second chamber 4 are provided with seal sleeve 12, and displacement connector 8 passes through from seal sleeve 12.
Steam condensate discharger, this device includes check-valves, drain valve 19, lime set system 20；The lime set outlet 9 of check-valves connects drain valve 19, and drain valve 19 connects lime set system 20.
During work, steam can lean on the pressure of steam to open inlet baffle 10 after entrance 1 pipeline entrance system, after steam is except mist net 11, opens sealing baffle 7, and then steam discharges out-of-bounds system through steam (vapor) outlet 2.This is normal steam flow trace.
If containing a small amount of lime set in steam, can flow to inside the condensate tank of the first chamber 3 bottom by steam except mist net 11 when, and it is discharged to lime set system 20 by the drain valve 19 being connected.
nullIf moment occurs that substantial amounts of water exists in steam，Drain valve 19 cannot completely removal system when，The liquid level of condensate tank just will rise，Liquid level goes up when，On the one hand magnetic lime set ball float can pass through buoyancy rise slowly，Still further aspect，Liquid level goes up when，Float level meter 13 also can start rise slowly，The when that float level meter 13 going up，By insulation connecting material，Connect brush 17 and also can start rise slowly，The when that connection brush 17 going up，Faradic current also can start to go up，The when that faradic current increasing，The anti-push magnetic of energising Magnet 18 also will rise，That is the rise displacement of ball float increases as well as the increase of liquid level，The when that liquid level at condensate tank increasing to certain displacement amount，By displacement connection member，Sealing baffle 7 also can be closed，The when of until completely closing，Now the lime set in condensate tank can lean on the pressure reduction between steam and lime set to be discharged to lime set system 20.When the liquid level of water is reduced to certain displacement amount when, the propulsive thrust of ball float also can reduction slowly, now ball float will decline slowly, finally open sealing baffle 7.After the complete removal system of lime set, ball float also can be reduced to minimum, connects brush 17 and also can be reduced to minimum, and faradic current also can be reduced to almost nil state, now sealing baffle 7 also can fully open again, by supply the outlet downstream system of steam fluxoid.
There is the phenomenon ruptured in the ball float of entrance system, and the operation of system can also be by regulating faradic size, it is ensured that anti-push magnetic also can valve for feeding；If there is the phenomenon of power-off in system, on the one hand can maintain the properly functioning of system by using ups system, if not having ups power system, the only buoyancy system by ball float can also strengthen the displacement of system, also can effectively prevent lime set from entering down-stream system, be dual fail-safe system.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; change can be readily occurred in or replace, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with scope of the claims.
