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 pneumatic slag flat gate valve.
The technical solution of the utility model is：
A kind of pneumatic slag flat gate valve, including valve body, flange one, flange two, flashboard, pressurize circle, bearing ring, buffering are close
Seal block, holder, piston rod, pneumatic actuating 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 indent on rectangular channel, in indent in rectangular channel be equipped with pressurize circle；Valve body lower portion interface
Equipped with concave rectangular channel in flashboard is accommodated, bearing ring is equipped in concave rectangular channel inside；Valve body upper end passes through bolt and flashboard
Chamber connects；Flashboard chamber upper end is connect by bolt with holder, and pedestal upper end is connected with pneumatic actuating device by bolt；Pneumatic driving
The output end of dynamic device cylinder is equipped with metal o-ring；Cylinder top is equipped with air inlet, and air inlet passes through two-way switch and gas cylinder
Connection；Exhaust outlet is additionally provided on cylinder；Piston rod is provided through in holder, pneumatic actuating device is stung by gear and piston rod
Connection is closed, piston-rod lower end is connect with valve rod, and valve rod is connect with flashboard；Pressurize circle one is that a V-shaped groove structure is opened on rectangular block,
Rectangular block side has hangnail protrusion.
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 pneumatic actuation, 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.
Specific implementation mode
The utility model is further described in 1-2 with reference to the accompanying drawings of the specification.
A kind of pneumatic slag flat gate valve, including valve body 1, flange 1, flange 29, flashboard 3, pressurize circle 4, bearing ring
11, cushion seal block 5, piston rod 6, holder 7, pneumatic actuating device 8；
Valve body 1 is docked by bolt with flange 29 by flange 1 and is formed；1 top interface of valve body is equipped with for flashboard 3
By indent on rectangular channel, in indent in rectangular channel be equipped with pressurize circle 4；
1 lower part interface of valve body is equipped with the interior concave rectangular channel for accommodating flashboard 3, is equipped with bearing ring in concave rectangular channel inside
11；
1 upper end of valve body is connect by bolt with flashboard chamber 10；
10 upper end of flashboard chamber is connect by bolt with holder 7, and 7 upper end of holder is connected with pneumatic actuating device 8 by bolt,
The output end of 8 cylinder of pneumatic actuating device is equipped with metal o-ring；Cylinder top is equipped with air inlet, and air inlet passes through two-way switch
It is connect with gas cylinder；Exhaust outlet is additionally provided on cylinder；
Piston rod 6 is provided through in holder 7, pneumatic actuating device 8 is connected by gear and piston rod 6, piston
6 lower end of bar is connect with valve rod 12, and valve rod 12 is connect with flashboard 3.
Pressurize circle 1 is that a V-shaped groove structure is opened on rectangular block, and rectangular block side has hangnail protrusion.
Flashboard 3 is placed in flashboard intracavitary when valve opening；Flashboard 3 cuts off 1 channel of valve body when valve is closed.
Valve body 1 is facilitated later maintenance and is replaced sealing ring using flange 1 and two combined connecting structure of flange.Flashboard 3 passes through
Bearing ring 5 is worn, 3 end of flashboard is absorbed in bearing ring, and bearing ring deformation is made to be dissolved into valve body 1, is realized to the buffering of flashboard 3 and close
Envelope；
Pneumatic actuating device 8 is pumped by piston rod, and flashboard 3 is driven to be turned on and off.
