The present invention has abandoned the pattern that lever adds spring fully.
Utilizing static pressure to realize closing the automatic full-automatic oil tank water cut-off device of protecting of direct floating of valve is to take following technical scheme to realize:
Utilize static pressure realize to close valve automatically the full-automatic oil tank water cut-off device of direct floating of protection comprise the water cut-off device exterior bowl, go up the centralized positioning orifice plate, debugging flange port, debugging flange port flange, advance/oil return opening, keg float, go up centralized positioning conduit (debugging pipe), centralized positioning cover, draining valve and outlet pipe down.
Be provided with a debugging flange port that is higher than vaulted end socket at water cut-off device exterior bowl top, the bottom is provided with the centralized positioning orifice plate in the debugging flange port, is provided with center positioning hole in the middle part of the last centralized positioning orifice plate, debugs flange port top the debug port flange is installed; Being provided with one in water cut-off device exterior bowl top one side advances/oil return opening; In the water cut-off device exterior bowl keg float is housed, described keg float is cylindrical, and hollow is vertically placed, and this keg float height approximately is about 1.5 times of keg float diameter.Described keg float top is provided with centralized positioning conduit (debugging pipe), last centralized positioning conduit (debugging pipe) is communicated with keg float, last centralized positioning conduit (debugging pipe) is inserted in the debugging flange port by the center positioning hole dress at last centralized positioning orifice plate middle part, and sealing cap is equipped with in last centralized positioning conduit (debugging pipe) upper end.
The bottom of keg float is provided with draining valve, and draining valve has valve head and valve seat, and valve head is assembled by valve rod, catch, sealing ring, pad, nut.Valve rod is installed in the keg float bottom by connector, in water cut-off device exterior bowl bottom valve seat is housed, catch, sealing ring, pad and nut are housed on the valve rod successively, on valve seat top centralized positioning cover down is housed, centralized positioning cover top is provided with centre bore, is provided with the water outlet filtering holes around the centralized positioning cover, valve rod passes the centre bore that centralized positioning cover top is provided with, the sealing ring of valve head cooperates with valve base sealing, and outlet pipe is equipped with in water cut-off device exterior bowl bottom, and outlet pipe top is communicated with the valve seat delivery port.
In the described keg float weight instrumentality can be housed, the weight instrumentality adopts liquid weight instrumentality or solid weight instrumentality.
Describedly advance/oil return opening is equipped with into/oil return pipe and advancing/the oil return opening adpting flange.
The present invention utilizes static pressure realize to close the valve operation principle of the full-automatic oil tank water cut-off device of direct floating of protection automatically: when oil-water mixture by the user big jar through advance/oil return opening, by advance/after oil return pipe enters in the water cut-off device exterior bowl; through precipitate and separate; open fire is sunken to bottom in the water cut-off device exterior bowl, oil product through advance/oil return opening returns in big jar of the user.Water cut-off device of the present invention through advance/big jar of oil return opening and user's discharge outlet is connected, and after opening big jar of user's water discharging valve, water cut-off device of the present invention has just formed the Communicating device relation for big jar with the user.Owing to the static pressure difference edge that the difference in height between big tank level of user and the water cut-off device bottom discharge valve produces is solid; even the buoyancy of open fire keg float generation more after a little while is equal to or slightly greater than the deadweight of keg float in water cut-off device; keg float still can not float; valve still keeps original tight closing state, can utilize static pressure to realize closing valve and protect automatically.When water level in the water cut-off device rises to 85% left and right sides of keg float height, the buoyancy that this moment, keg float produced will tend to gradually greater than the deadweight of keg float and the static pressure sum on the draining valve port.In case buoyancy is greater than these two sum, keg float begins come-up, and draining valve is mentioned by force to be opened.And in a single day valve is opened, airtight condition is promptly destroyed, and the static pressure that was subjected to originally on the valve head of water cut-off device draining valve disappears immediately, and the buoyancy that produces on the keg float rises sharply because of the disappearance buoyancy of this static pressure, thereby to highest point, make draining valve open fully the valve head fast lifting.
After draining valve was opened, water level descended thereupon in the water cut-off device, and keg float descends with the oil-water interfaces line as a free buoyancy aid this moment.When the oil-water interfaces line dropped to floating 10% left and right sides of disclosing height, the valve head of keg float below had fallen in the draining valve valve seat, with drain shut valve (blocking).Meanwhile big innage produces immediately to the static pressure of valve port, makes the tighter of drain shut valve, utilizes static pressure to realize closing valve and protects automatically.So go round and begin again.
Because the upper and lower concentric locating hole that all is provided with in the water cut-off device defines keg float and can only do straight line elevating movement up and down.Thereby guarantee that valve head can both not fall in the valve seat all the time with not moving partially.
In addition because the delivery port of outlet pipe is located at the bottommost of the vaulted end socket in water cut-off device bottom, the deposit in the capital will be deposited at the bottom of the water cut-off device jar in the time of each draining is gone out outside the jar, has played the effect of self-cleaning.
It is reasonable in design that the present invention utilizes static pressure to realize closing the automatic full-automatic oil tank water cut-off device of protecting of direct floating of valve; simple in structure, compact; utilization is treated the deadweight of liquid in the large-scale storage tank of draining and the static pressure that produces; act on the valve head back side of the draining valve of the full-automatic oil tank water cut-off device of direct floating, thereby pressurize self-insurance behind the valve of realization pass.Make the switch valve process realize quick, reliable, tight, watertight ideal effect.The present invention utilizes static pressure to realize that the full-automatic oil tank water cut-off device of direct floating that closes the automatic protection of valve can be widely used in storing various oil; in the storage tank of chemical liquid and liquefied gas, the open fire that separates deposition discharges automatically and can close automatically before open fire is about to rack up.Because water cut-off device open and close draining valve of the present invention by upper and lower twice control line control, has a time period to open next time respectively between the valve after closing valve.This time interval is very beneficial near nearly step separation of the oil-water emulsion layer the oil-water interfaces, thereby has reduced the oil content in the draining.
