Description
Technical field
The invention belongs to low concentration coal-bed gas pipe conveying equipment field, more particularly, to a kind of abandoned mine gas utilization
Unit antiseize gas control valve.
Background technology
In low concentration abandoned mine, coal bed gas (device in Gas) pipe-line transportation system, gas inlet control valve is generally used for watt
The control of this generating set air inflow size.Existing control valve uses pneumatic control valve and motor-operated control valve.Gas inlet control
The installation of valve processed is predominantly located at position between 500KW gas electricities unit and device in Gas secondary air inlet valve.Control valve is main by 24V
Direct current generator, valve body, valve plate, valve rod rotary shaft etc. are constituted, and its valve plate is fixed by valve rod, and valve rod two ends are fixed on valve body both sides
In axis hole, by Electronic control module controls gas control valve aperture by controlling valve rod to rotate, regulation device in Gas tolerance is supplied
Give, ensure gas electricity unit safety even running.Because aqueous in coal bed gas, coal dust amount is larger, and moisture content is more in gas
For faintly acid, there is stronger corrosiveness to gas control valve critical piece, gas electricity unit through operation after a while,
Gas control valve valve rod and valve plate are to be corroded or dust jam, cause electric control system failure, cause unit to exceed the speed limit, seriously
Cause control module or motor burning etc. endanger.So as to add equipment operating cost and equipment safety hidden danger.It is at present
Only, gas electricity unit air intake control valve is all this class formation.
The content of the invention
The purpose of the present invention is to overcome the defect of prior art there is provided a kind of antiseize, the gas electricity of service life length
The gas control valve that unit is used.
Technical solution of the present invention is as follows：
A kind of abandoned mine gas utilization unit antiseize gas control valve.The control valve includes combustion gas control valve body, bearing
Bore, valve rod, bearing cap, bearing saddle bore is provided with bearing valve body, bearing is arranged in bearing saddle bore.Valve rod is nested in axle
In bearing bore, positioned at valve body both sides, its function is mainly position and valve rod outermost contacts and the 24V direct currents of fixed combustion gas valve plate
The neck connection of the electronic contact of machine, is realized to valve plate 0-90 by control system module0Opening and closing.The master of valve body
It is the bridge that gas secondary air intake valve is connected with Gas Generator Set to want function.It is anti-that rolling bearing or sliding bearing are installed in valve body
Only gas control valve valve rod and valve plate are corroded or dust jam, prevent electric control system failure.It is provided with outside bearing block
Bearing cap, can add lubricating grease, ensure that valve rod rotates flexibly not jam, while prevent corrosion and dust from entering, it is convenient regular
Maintaining, prevents scaling loss electronic control module and motor, increases the service life, and reduces operation expense.
The present invention has following effect：Now install control valve and motor connection end additional rolling bearing or sliding bearing, every time dimension
Mobile bearing or sliding axle during shield maintenance at control valve two ends add moderate lubrication fat, can eliminate that to hold valve rod rotating shaft stuck existing
As.With cost input is few, features simple structure, it is easy to implement, while can effectively prevent gas electricity unit gas control valve from opening
Outpost of the tax office plug, failure, prevent valve rod from corroding, and reduce control module and motor burning, maintain easily maintenance, and extension is dropped using receiving the order
Low operation expense.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of abandoned mine gas utilization unit antiseize gas control valve.The control valve bag
Include and be provided with bearing saddle bore 4, axle on combustion gas control valve body 1, bearing saddle bore 2, valve rod 3, bearing cap 4, bearing 5, valve body 1
5 are held to be arranged in bearing saddle bore 4.Valve rod 3 is nested in bearing hole, positioned at valve body both sides, and its function is mainly fixed gas valve,
6 position and valve rod outermost contacts are connected with the neck of the electronic contact of 24V direct current generators, are realized by control system module
To valve plate 0-900Opening and closing.The major function of valve body is the bridge that gas secondary air intake valve is connected with Gas Generator Set
Beam.It is to prevent gas control valve valve rod and valve plate to be corroded or dust jam that rolling bearing or sliding bearing are installed in valve body, is prevented
Only electric control system failure.Bearing cap 4 is installed outside bearing block, the axis hole of both sides external valve rod 3 of gas control valve body 1
Position is provided with rolling bearing 5, and valve rod 3 is installed on the endoporus of bearing 5, and the spindle nose end of valve rod 3 is protrusion strip 8 and electronically controlled motors
Axle groove 9 is connected.The present invention is rotated by valve rod 3 and realizes valve plate in use, rotor rotational band ovable valve stem 3 is rotated
Closure.Bearing cap 4 is provided with rolling bearing, lubricating grease can be added by dismantling bearing cap, increase bearing service life.
