Description
Technical field
The present invention relates to a kind of special service valves, more particularly to a kind of air-transport system outlet valve.
Background technology
Pneumatic ash transmitting system is as the part that boiler accessory machinery system is whole boiler system, in order to preferably adapt to pot
The needs of furnace system normal work, avoid improper factor from damaging boiler operatiopn, and it is normal that guarantee does not influence boiler system
It works, durable valve must be used in pneumatic ash transmitting system.In addition in cement, the also extensive use of the industries such as steel.
Currently, the pneumatic ash transmitting system outlet valve generally used is substantially to be mostly lock（Plate）Valve；Although can ensure
Good sealing, but two kinds of valve arrangement complexity, manufacture craft require harshness, maintenance difficult, cost higher, the valve of double gate valves
Plate is that face contacts with valve seat, be easy to cause certain dust stratification, valve is caused to be not closed completely.
The air bleeding valve of other forms cannot all be effectively protected pneumatic ash transmitting system, once breaking down, will cause greatly
Loss.
Invention content
The purpose of the present invention is to provide a kind of air-transport system outlet valves, and outlet valve is using turnover plate type sealing knot
Structure, entire valve shape are square chest type, block and open with the sealing valve plate on turn wall under the action of pneumatic actuation cylinder
Ash handing pipeline comes the opening and closing of control valve, the less convenient disassembly of rotatable parts, and hardly wears.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of air-transport system outlet valve, the outlet valve include suction flange soldering member, outlet(discharge) flange soldering member, soldering
Babinet, buffer stopper, valve plate, sealing ring, sealing cover, round nut, wobble plate, pendulum shaft, right plate, left plate, asbestos pad, bearing
Seat, pneumatic head；The installation gasket of suction flange soldering member and outlet(discharge) flange soldering member and soldering babinet, and pass through bolt, spiral shell
Female, plain washer connection；The installation asbestos pad of right plate and left plate and soldering babinet, and by stud, acorn nut and
Plain washer connects；Bearing block is fixed on by O-ring seal, stud, acorn nut and plain washer on right plate；Pendulum shaft
It is penetrated into bearing block after installing copper sheathing, backbone sealing ring and spacer additional, shaft block ring is used in combination to fix；Pendulum shaft stretches out bearing support part
Divide and connect with pneumatic head, pneumatic head is fixed on by stud, acorn nut and plain washer on bearing block；Wobble plate passes through flat key
It is sleeved in pendulum shaft, and is bolted.
A kind of air-transport system outlet valve, the interior hexagonal flush end holding screw pass through hexagonal (hexagon)nut, spiral shell
The O-ring seal of cap is fixed in wobble plate, buffer stopper, valve plate, round nut, is stacked successively on interior hexagonal flush end holding screw,
It is fixed again with sealing cover.
A kind of air-transport system outlet valve, the pneumatic head outside are equipped with position detecting switch.
A kind of air-transport system outlet valve, the adjustment block are welded on soldering babinet and by adjusting spiral shell
Bolt connecting lateral plate is through nut locking.
Outlet valve is pumped out mounted on storehouse on material mouth pipeline, only when the pressure in defeated ash cellar pump reaches scheduled pressure,
This valve is just opened.It is to avoid diluted phase transport phenomenon occur when defeated ash starts that it, which is acted on, and it is two-phase transportation to make defeated ash initially.
The consumption of compressed air can be reduced in this way, while defeated grey ability can be improved.
Advantages of the present invention is with effect：
1. outlet valve of the present invention uses turnover plate type sealing structure, entire valve shape is square chest type, in the work of pneumatic actuation cylinder
Opening and closing of the ash handing pipeline come control valve are blocked and open with the sealing valve plate on lower band turn wall.Valve mechanism letter
It is single, novel, it is economical and practical.Its sealing element is only simple silica gel sealing ring, this sealing ring is fixed in sealing valve plate, tears open
It unloads conveniently, and hardly wears；Its rotatable parts is less, and corresponding vulnerable part is also smaller, and the maintenance maintenance of valve is extremely convenient.
2. outlet valve of the present invention is also very unique in structure design, using turnover plate type, when unlatching, avoids grey circulation road almost
Do not wear valve plate.

Fig. 2 is discharge valve structure left view of the present invention；
Fig. 3 is discharge valve structure vertical view of the present invention.
Specific implementation mode
The present invention is described in detail for illustrated embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 1 to 3, a kind of air-transport system wear-resistant discharge valve of the present invention, including suction flange soldering member
1, outlet(discharge) flange soldering member 2, with stud, nut 9 be mounted on soldering babinet 3 on.
Buffer stopper 4 is made of silica gel, and support steel valve plate 5 plays cushioning effect.Pass through wobble plate 10, interior hexagonal flush end tightening
Screw 25, sealing cover 6, transfers force on the center of steel valve plate 5 round nut 7, finally arrives sealing ring 8.The bullet of buffer stopper 4
Property also act as the stress on the mouth periphery for correcting sealing ring 8 and suction flange soldering member 1, ensure strict sealing.
Wobble plate 10 connects pendulum shaft 11 and is connected on pneumatic head 17 by bearing block 16.13 supporting bearing base 16 of right plate is used
Stud, nut pass through the asbestos pad 15 as sealing and are connected on soldering babinet 3.Bearing block 16 passes through the O-shaped of bearing block
Sealing ring 20 is fixed on stud, acorn nut on right plate 13.Pendulum shaft 11 installs copper sheathing 18, backbone sealing ring 19 additional
It is penetrated into bearing block 16 with after spacer 24, shaft block ring 22 is used in combination to fix.The effect of backbone sealing ring 19 be prevent material into
Enter to damage bearing.
Wobble plate 10 is sleeved on by flat key 23 in pendulum shaft 11, and is bolted.
Left plate 14 is passed through as the asbestos pad 15 sealed with stud, nut, is connected on soldering babinet 3.
Air-transport system of the present invention realizes on and off with wear-resistant discharge valve wobble plate 10 by about 90 degree of swing,
Sealing valve plate and sealing ring avoid the channel of material when unlatching, prevent valve wear.
The bolt 27 that air-transport system wear-resistant discharge valve adjustment block 31 of the present invention is welded on soldering babinet 3 finely tunes the right side
Side plate 13（Bolt hole on right plate 13 is kidney slot, therefore can be moved）, make steel valve plate 5 and suction flange soldering member 1
Mouth ensure in one plane, after being adjusted in place with adjusting nut 28 lock.
Outlet valve left plate 14 is equipped with hanging ring 33, is convenient for the carrying and installation of valve.
There are position detecting switch in pneumatic 17 outside of head of air-transport system outlet valve of the present invention, for judging valve
On off state.Pneumatic head is remote by the air inlet of two compressed air inlets, outlet 32 on the pneumatic head of solenoid valve control and outlet
The open and close of process control valve.
Air-transport system of the present invention is pumped out mounted on storehouse on material mouth pipeline with outlet valve, only when the pressure in defeated ash cellar pump
When power reaches scheduled pressure, this valve is just opened.It is to avoid diluted phase transport phenomenon occur when defeated ash starts that it, which is acted on, makes defeated ash
It is initially two-phase transportation.The consumption of compressed air can be reduced in this way, while defeated grey ability can be improved.
