Specific implementation mode
Referring to Fig. 1 and Fig. 2, a kind of float-type steam-water separation valve that can overcome the failure phenomenon that builds the pressure of the present invention, in valve body 1
Top and bottom end be connected separately with outlet 7 and entrance 13, be equipped with outlet(discharge) flange 5, the outlet(discharge) flange 5 in the bottom end of the outlet 7
The bottom end of the outlet 7 is covered, and is equipped with gas passage 8；The top of the valve body 1 is sealed by valve flange 4 and the outlet(discharge) flange 5
Connection；Floating drum 2 is equipped in the valve body 1, which is characterized in that the gas passage 8 is located at the side of valve body 1,
Between 8 lower end of gas passage and the side of close valve body 1 be equipped with strut 6, the lower end of the strut 6 by fulcrum shaft 3 with
One end of float counter balance 11 is hinged, and the other end of the float counter balance 11 is connect with the top for the floating drum 2 being disposed below；At this
Float counter balance 11 is equipped with the seal disc 9 stretched out upwards, and the upper surface of the seal disc 9 is opposite with the lower end of gas passage 8
It answers.
It is equipped with position-limit mechanism 10 in the both sides of the float counter balance 11（Float counter balance 11 is located at therebetween by n shapes）, ensure
Float counter balance 11 will not be deviated when moving up and down, and floating drum 2 is avoided to shift when moving up and down and form retardance.
Gasket 12 is equipped between the valve flange 4 and outlet(discharge) flange 5.
Referring to Fig. 2, the cross section of the strut 6 is rectangle, the float counter balance 11 and the hinged one end of the strut 6
Equipped with U-board 14, U-board 14 is clipped in the both sides of the strut 6 of rectangle, and is hinged by fulcrum shaft 3.
The present invention reaches the sealing effect of lift-off seal disk 9 using leverage, meanwhile, using rectangle strut 6 with
Position-limit mechanism limits the movement locus of floating drum 2, ensures that valve can also work normally in the environment for shaking or waving.
The present invention is in gas-liquid environment, and when liquid level is relatively low, the gravity torque of floating drum 2 is in main function status, floating drum 2
It falls, seal disc 9 leaves the lower end of gas passage 8, valve opening（As shown in Figure 2）, ensure that gas passes through；When liquid level is increased to
When to a certain degree, the buoyancy torque of floating drum 2 overcomes gravity torque, floating drum 2 to float, and seal disc 9, which moves up, makes valve close, and prevents liquid
Body passes through.When liquid level declines, since the gravity torque of floating drum 2 is more than the torque that gas pressure difference generates inside and outside valve, to make
Valve can overcome the generation of " build the pressure failure " phenomenon.
The innovation of the invention consists in that：
（1）Floating drum 2 is rotated around fulcrum shaft 3, reduces the possibility of the deformation of floating drum 2 card resistance in valve body.
（2）Using lever principle, amplify the effect of power：When liquid level rises, floating drum 2, which floats, drives seal disc 9 to lead to gas
Road 8 is closed, and liquid is prevented to pass through；When liquid level declines, floating drum 2 is fallen, valve opening, ensures that gas passes through.
（3）Using the synergy of position-limit mechanism 10 and the strut 6 of rectangle, the movement locus of floating drum 2 is limited, to avoid dress
It sets and occurs uncontrollable risk under vibrations or swinging condition.
（4）Valve top uses flanged joint, and easy disassembly, maintenance, upper and lower side is also simple and efficient to realize using flange
Installation fix.
The seal disc 9 of the present invention, which is located at below gas passage 8, has special technique effect.If seal disc 9 is located at
The upper surface of gas passage 8（It is upward through and seal disc 9, fulcrum and the seal disc 9 of lever out of gas passage 8 by connecting rod
Place-exchange）, when liquid level is high, gas pressure is big in use environment, floating drum 2 is increased with liquid level, and seal disc 9 is under
Row.But but have the tendency that uplink, the movement tendency of this " contradiction " can be cut under the action of outer gas pressure difference including seal disc 9
Weak sealing effect, it is more likely that cause to reveal；And high pressure gas act as " opening " work to seal disc in the structure valve body
With.In contrast, structure of the invention be not present this problem, valve because liquid level increases close after, overcome inside and outside valve
Draught head reopens valve, overcomes the pressure torque that builds the pressure using the gravity torque of floating drum.
One of the present invention uses example：
Shanghai east China-middle sea 135K-TEU container ship electrolysis handles ballast water project, is electrolysed flow 16m3/h, arranges hydrogen flowrate
3.17m3/h.The valve is installed on electrolysis cells surge tank dehydrogenation pipeline, gas-liquid separation effect is good：When low liquid level, floating drum
It falls, valve opening, gas passes through；When liquid level is increased to floating drum submergence 95mm or more, floating drum floats, and valve is closed, resistance
Every liquid；And after valve closing, during liquid level decline, 2.2bar gas pressures can be overcome, reopened, avoided
The phenomenon that " build the pressure failure ".
