Specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model one kind can overcome the float-type steam-water separation valve for the failure phenomenon that builds the pressure,
The top and bottom end of valve body 1 are connected separately with outlet 7 and entrance 13, are equipped with outlet(discharge) flange 5, the outlet in the bottom end of the outlet 7
Flange 5 covers the bottom end of the outlet 7, and is equipped with gas passage 8；The top of the valve body 1 passes through valve flange 4 and the outlet(discharge) flange
5 are tightly connected；Floating drum 2 is equipped in the valve body 1, which is characterized in that the gas passage 8 is located at close to the side of valve body 1
Place is equipped with strut 6 between 8 lower end of gas passage and the side of close valve body 1, passes through fulcrum in the lower end of the strut 6
Axis 3 and one end of float counter balance 11 are hinged, and the other end of the float counter balance 11 and the top for the floating drum 2 being disposed below connect
It connects；Be equipped with the seal disc 9 that stretches out upwards on the float counter balance 11, the upper surface of the seal disc 9 under the gas passage 8
It holds corresponding.
It is equipped with position-limit mechanism 10(n shape in the two sides of the float counter balance 11, float counter balance 11 is located at therebetween), it ensures
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 two sides of the strut 6 of rectangle, and is hinged by fulcrum shaft 3.
The utility model reaches the sealing effect of lift-off seal disk 9 using leverage, meanwhile, use the strut of rectangle
6 and position-limit mechanism, the motion profile of floating drum 2 is limited, guarantees that valve can also work normally in the environment for shaking or waving.
The utility model is in gas-liquid environment, and when liquid level is lower, the gravity torque of floating drum 2 is in main function status,
Floating drum 2 is fallen, and seal disc 9 leaves the lower end of gas passage 8, and valve opening (as shown in Figure 2) guarantees that gas passes through；Work as liquid level
When increasing to a certain extent, the buoyancy torque of floating drum 2 overcomes gravity torque, and floating drum 2 floats, and seal disc 9, which moves up, closes valve,
Liquid is prevented to pass through.When liquid level declines, since the gravity torque of floating drum 2 is greater than the torque that gas pressure difference generates inside and outside valve,
To allow valve to overcome the generation of " build the pressure failure " phenomenon.
The innovative point of the utility model is:
(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) utilize 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, guarantees that gas passes through.
(3) using the synergy of position-limit mechanism 10 and the strut 6 of rectangle, the motion profile of floating drum 2 is limited, to avoid dress
It sets and occurs uncontrollable risk under vibration or swinging condition.
(4) valve top uses flanged joint, easy disassembly, maintenance, and upper and lower side also uses flange simple and efficient to realize
Installation fix.
The seal disc 9 of the utility model, which is located at below gas passage 8, has special technical effect.If seal disc 9
The upper surface of gas passage 8 is located at (to be upward through out of gas passage 8 by connecting rod and seal disc 9, the fulcrum and seal disc of lever
9 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 therewith
Downlink.But but have the tendency that uplink, the movement tendency meeting of this " contradiction " under the action of outer gas pressure difference including seal disc 9
Weaken sealing effect, it is more likely that cause to reveal；And high pressure gas is " opening " to the effect of seal disc in the structure valve body
Effect.In contrast, this problem is not present in the structure of the utility model, after valve is closed because of liquid level raising, overcomes valve
Door internal and external pressure difference reopens valve, overcomes the pressure torque that builds the pressure using the gravity torque of floating drum.
One of the utility model uses example:
Shanghai east China-middle sea 135K-TEU container ship electrolysis method handles ballast water project, is electrolysed flow 16m3/h, arranges hydrogen
Flow 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 is fallen, and valve opening, gas passes through；When liquid level is increased to floating drum submergence 95mm or more, floating drum floats, and valve closes
It closes, liquid barrier；And after valve closing, during liquid level decline, 2.2bar gas pressure can be overcome, reopened, kept away
The phenomenon that having exempted from " build the pressure failure ".
