Description
Technical field
The utility model is suitble in nominal diameter for 1000mm hereinafter, the circulation and resistance of liquid mixed ore pulp, clinker pipeline
Disconnected gate valve.
Background technology
Now nominal diameter be 1000mm or less, nominal pressure 16MPa hereinafter, the operating modes occasion such as transfer ore pulp, lime-ash
General slag flat gate valve, bottommost are commonly designed concavity, and during valve switch, and fluid and dregs can leak
Into valve cavity, after a period of use, in bottom, recess has dregs accumulation, and flashboard is caused to fit badly.On valve body top
Packing padding formula crush seal is usually selected in sealing between ram movement, and ram movement resistance is larger, and occurs often
Leakage, influences valve tightness and service life.
Invention content
The purpose of this utility model is to provide one kind being avoided that above-mentioned insufficient hydraulic pressure slag flat gate valve.
The technical solution of the utility model is：
A kind of hydraulic pressure slag flat gate valve, including valve body, flange one, flange two, flashboard, pressurize circle, bearing ring, buffering are close
Seal block, holder, piston rod, fluid pressure drive device；
Valve body, which by flange one is crossed bolt with flange two-way and docked, to be formed；Valve body top interface be equipped with for flashboard by
Rectangular channel in indent is equipped with pressurize circle in indent in rectangular channel；
Valve body lower portion interface is equipped with the interior concave rectangular channel for accommodating flashboard, is equipped with bearing ring in concave rectangular channel inside；
Valve body upper end is connect by bolt with flashboard chamber；
Flashboard chamber upper end is connect by bolt with holder, and pedestal upper end is connected with fluid pressure drive device by bolt；Hydraulic pressure
The output end of driving device is equipped with metal o-ring；Fluid pressure drive device top is equipped with inlet, and inlet passes through switch and liquid
Cylinder pressure bottle connects；Leakage fluid dram is additionally provided on fluid pressure drive device；
Piston rod is provided through in holder, fluid pressure drive device is connected by gear and piston rod, under piston rod
End is connect with valve rod, and valve rod is connect with flashboard；
Pressurize circle is that a V-shaped groove structure is opened on rectangular block, and rectangular block side has hangnail protrusion；
Bearing ring is that indent wedge groove is offered on rectangular block, and wedge groove lower part is equipped with gill shape compression groove.
The utility model advantageous effect is：
1, the utility model is annular seal ring, and close contact reaches two-way in flashboard in opening in a compressed state
Sealing, sealing are reliable and stable.The valve body cavity inner product quantity of slag is small, and flashboard moves up and down flexible.It reduces since the sealing of material filling type is made
It is excessive at frictional resistance, it opens and closes more flexible.By the way of hydraulic-driven, valve is sealed, and movement is flexible,
The stroke controllable precise system of flashboard.
2, the utility model pressurize circle compression spreading mode is internal expanding type, and when compression is closely against on flashboard, sealing effect
Well.Again because material selection is abrasion resistant polyurethane, belong to soft seal, frictional resistance is small.
Description of the drawings
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the pressurize loop knot composition of the utility model.
Fig. 3 is the bearing ring structure chart of the utility model.
Specific implementation mode
The utility model is further described in 1-3 with reference to the accompanying drawings of the specification.
A kind of hydraulic pressure slag flat gate valve, including valve body 1, flange 1, flange 29, flashboard 3, pressurize circle 4, bearing ring
