Description
Technical field
The present invention relates to a kind of blast furnace top non-toggle structure without counterweight pressure-adjustable diffusion valve.
Background technology
Coal gas tedge of the raw gas through upper blast furnace generated during blast furnace ironmaking, is sent at dust pelletizing system purification
Reason.To keep the stabilization of conditions of blast furnace, the gas pressure in blast furnace need to be stablized in certain scope.Such Top of BF coal
Bleeding valve on Qi Guan roads must be installed, when furnace pressure is excessively high, diffusion valve is opened, furnace pressure is adjusted, in addition, blast furnace goes out
During trouble hunting, diffusion valve is opened, coal gas diffusion is fallen, convenient for safety inspection.
For many years, bleeding valve always using lever counterweight diffusion valve, by counterweight pressure completed by the closing of valve, is tied
Structure is huge, and valve is heavy.Although the common no balance weight diffusing valve on furnace roof of subsequent development is without counterweight, when valve is closed
Mechanism is self-locking state, if furnace pressure raises suddenly, due to mechanism self-locking, valve cannot be opened, and equally exist security risk.
And conventional overturning structure is using hydraulic cylinder when realize self-locking, because there are the reason for moment variations in switching process, nothing
Method accurately controls self-locking pressure.
The content of the invention
In view of the above-mentioned problems, the present invention provides, a kind of blast furnace top for being capable of restraining force suffered by precision control valve lid is non-to be turned over
Rotation structure is without counterweight pressure-adjustable diffusion valve.
In order to achieve the above objectives, the present invention include be arranged on blast furnace roof valve body, with the valve body cooperation valve deck, with
Hinged connector, the flexible dress with two limiting devices of connector both ends cooperation and for constraining valve deck at the top of valve deck
It puts；It is provided at the top of the valve body and diffuses hole；When the valve deck and the valve body are closed, and the axis of the telescopic device
Line is parallel with the axis for diffusing hole.
Further, the limiting device is included at least aligns the upright guide rail of setting with the axially bored line that diffuses, described
The axis of the upright guide rail of two limiting devices and the axis co-planar for diffusing hole；The connector both ends are respectively arranged with and institute
State the idler wheel or sliding block of upright guide rail cooperation.
Further, the telescopic device includes two hydraulic cylinders for being arranged on valve deck both sides, the cylinder body of the hydraulic cylinder
It is connected with blast furnace roof, the piston rod of the hydraulic cylinder is connected with the connector.
Further, the limiting device further includes the horizontal guide rail that is correspondingly arranged with upright guide rail and for being connected
State the arc-shaped guide rail of horizontal guide rail and the upright guide rail.
Further, the distance between axis of the one end of the horizontal rail away from vertical rail and the vertical rail
Not less than valve deck along 1.5 times of the horizontal guide rail axis direction length.
Further, the top outer of the valve body is provided with male-tapered face, is provided on the inside of the valve deck and outer cone
The inner conical face of shape face cooperation, is both provided with flexible gasket on the male-tapered face and the inner conical face.
When valve deck needs to open, telescopic device movement along the track of limiting device, opens valve deck.Due to working as valve deck
When being closed with valve body, the axis of telescopic device aligns with diffusing the axis in hole and parallel, is ignoring the shadows such as gravity and frictional force
After sound, telescopic device is in balance between two forces shape body to the pressure of the valve body suffered by the restraining force and valve deck of valve deck, so this dress
Putting can be with restraining force suffered by precision control valve lid, and after valve body is more than restraining force to the pressure of valve deck, valve deck automatically opens.
