Description
Technical field
The utility model belongs to control valve unit, relates in particular to the control valve unit that utilizes aqueous medium Control work fluid.
Background technique
The water seal check valve is set, the connection and the cut-out of control gas pipe line in the RECOVERY OF CONVERTER GAS pipeline.Current, the water seal check valve of employing is connected and composed by valve body, flap, immersion tube, driving mechanism and level meter.The valve body symmetry, flanged surface is placed in the middle, is positioned under the water seal face, and flap and immersion tube are located in the valve body; The flap both sides are established minor axis and are fixed on the valve body by axle envelope and bearing integral mechanism respectively, and driving mechanism is connected with minor axis; Level meter directly is connected with valve body.Water-filling in the valve body, water seal face is higher than flanged surface, and profit uses water as sealing medium and opens and closes gas pipe line.When opening, rotate flap, make its complete leaving water front cover, passage turns on the gas-fire.When closing, the backward rotation flap immerses under the water seal face its end opening fully, closes gas passage.Its defective is: adopt symmetrical valve body, water seal face is higher than flanged surface, and flange leaks, and drawdown is if accident to leak the coal gas easily takes place in untimely moisturizing; Adopt axle envelope and bearing integral mechanism, when the axle envelope was damaged, corrosive liquids entered bearing, and bearing is short service time, changed the axle envelope and must remove bearing earlier, safeguarded inconvenience; Be located at flap both sides minor axis and be difficult to be subjected to the moment difference during rotation with one heart, easily jam, not even action; Minor axis and excessive, the rapid wear of flap joint load, even also damage flap and make flap distortion; Level meter directly links to each other with valve body, and under the influence that flap opens and closes suddenly or bessemerizes, the sealing water level fluctuations is big, and level meter can not show sealing water level real conditions in real time, brings very big difficulty for operation control; The equipment failure rate height, maintenance workload is big, directly influences converter and produces continuously.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model provides a kind of asymmetric water seal check valve, avoids flange to leak, leak gas, stable and reliable operation, reduce equipment failure rate and maintenance workload, reduction consumption, help pneumatic steelmaking production direct motion.
Asymmetric water seal check valve, form by valve body, flap and oil hydraulic cylinder, immersion tube and level meter, valve body is established suction port, air outlet, in establish flap and immersion tube, flap places immersion tube oral area top, be characterized in: described valve body is a non-symmetry structure, flanged surface is located at valve body top, the water seal face of being positioned at top can make internals easy for installation, can solve again that flange leaks, the gas leakage problem; Described immersion tube is provided with hollow steel pipe, flap is provided with long axis, long axis passes hollow steel pipe and the valve body that immersion tube is established, by axle envelope and valve seal, be packed on the valve body by bearing, oil hydraulic cylinder is connected with long axis, the Driven by Hydraulic Cylinder flap rotates, flap rotates flexibly, no longer is subjected to the torsion jam, has also strengthened the reliability that flap is connected with long axis; Described level meter two ends are connected with valve body, immersion tube respectively, and employing connecting tube structure can in time be reflected to SEA LEVEL VARIATION on the level meter, the coal gas that brings in the water in time can be entered in the valve body again, does not influence SEA LEVEL VARIATION; Valve body lower portion also is provided with blowdown valve, is connected with the dump tank of peripheral hardware, is used for the water seal check valve and gets rid of dirt.
Further improvement of the utility model, the upper shell of described valve body and lower shell body are connected and composed by its flange, and upper shell is little, and lower shell body is big, is non-symmetry structure.Upper shell sets out gas port, and coal gas is flowed out by the air outlet.Lower shell body establishes suction port and the immersion tube end opening connects.When flap was closed, coal gas was entered in the cavity that immersion tube, flap and water seal face constitute by suction port.When flap was opened, coal gas directly flowed out by the air outlet.Lower shell body is established the interface that connects the level meter intake pipe, connects through intake pipe and level meter.Establish the last stop block and the following stop block of flap in the lower shell body, the control flap stops state, and flap is parked in stop block, and the flap end opening immerses under the water seal face, and check valve is in closed condition; Flap is parked in down on the stop block, and flap is opened, and check valve is in opening state.The lower shell body bilateral symmetry is established through hole and the bearing spider that installs long axis, and long axis passes through hole, loads onto bearing fixing on bearing spider.Lower shell body also is provided with the blowdown valve connection interface, is connected with dump tank by blowdown valve, discharges the dirt of deposition.
The utility model further improves, and described flap is a semi-cylindrical shaped, and is concentric with valve body, be movably connected in air outlet and immersion tube suitable for reading between; Flap is established long axis, establishes an axle envelope and a bearing on the long axis, and long axis passes the steel pipe that the through hole established the valve body both sides and immersion tube are established, and is sealed and valve seal by axle, and the bearing fixing that establish at long axis two ends is on bearing spider; Long axis one end is connected with oil hydraulic cylinder, drives flap and rotate the passage of closing or turn on the gas-fire between last stop block and following stop block.
The another step of the utility model improves, and described immersion tube end opening is connected with the valve body suction port, and is suitable for reading relative with the air outlet across movable flap, exceeds water seal face; Immersion tube is established steel pipe, and is corresponding with the axis hole that long axis and valve body are established, and the center that promptly installs the through hole that back long axis, steel pipe, valve body establish coexists on the straight line, and pipe diameter is greater than long axis diameter, and long axis transmission is jam not, and rotation is flexible; Steel pipe is connected with immersion tube tightly, and water seal water is every outside immersion tube.Immersion tube is also established the interface that connects the level meter outlet pipe, is connected with the level meter outlet pipe, and the coal gas in the level meter is discharged in the immersion tube.
Last improvement of the utility model, described level meter is established intake pipe and outlet pipe; Intake pipe is communicated with the intake pipe interface that is located at lower shell body, water seal water enters in the level meter thus, in time show the water seal level change, outlet pipe connects with the exhaust port that is located on the immersion tube, the coal gas of being brought in the level meter by water enters in the immersion tube thus, eliminate the gases affect SEA LEVEL VARIATION, more can not cause coal gas to enter in the atmosphere with overflow.
During application, this water seal check valve is connected gas pipe line, rotates, open or close gas pipe line according to arts demand, instruction Driven by Hydraulic Cylinder flap.
Compared with prior art, advantage is: novel, compact structure, reasonable, and installation, operation and maintenance are conveniently stopped to leak, leak gas; Long axis transmission is jam not, and flap rotates flexibly, and equipment failure rate is low, and prolong working life, has reduced consuming and engineering time, guarantees the gas pipe line safe and stable operation, helps the continuous direct motion of STEELMAKING PRODUCTION.
