Description
Technical field
The present invention relates to a kind of alarming device, more particularly to a kind of safety valve of coal mine hydraulic supporting.
Background technology
Safety valve is control and one of the element of overload protection of coal mine hydraulic supporting, for controlling actual frock resistance simultaneously
It is no more than permissible value, make support that there is contractibility and constant-resistance, its performance quality directly affects support intensity and safety is
Number, influences the performance of support ability, influences support load capacity and deadweight ratio, influences miner's safety.
If support works less than specified setting load or between relatively low working resistance, it will causes following consequence：Top
The too early absciss layer of plate crushes, and causes coal wall caving, end to emit and then expand to kiting back timber, support and surrounding-rock system is lacked of proper care；Or
Support can not cut top in comparatively ideal position after frame, and during top plate deflection deformation, support only serves the work of a strong point
With being fractureed length so as to extend main roof, make working face periodic caving and be caving height to increase, ultimately resulted in
The large area periodic weighting of strength, or even wall caving occurs, kills, damage the serious accidents such as support by pressure.
In real work, setting load is had a great influence by artificial factor, and working resistance is horizontal partially after not only making actual setting load
It is low, and make it that the support works resistance of each support of working face is inconsistent, or even bigger difference be present.
Existing Safety Valve for Hydraulic Powered Support structure is made up of major parts such as valve body, valve element, valve casing, spring, adjusting screws.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art to provide a kind of reflection coal mine hydraulic supporting setting load in time
Setting load, superpressure LED warning high-flow safety valves with operating pressure, reduce roof accident, improve support service life, ensure
Working face is kept the safety in production.
The present invention includes valve body, valve element, valve casing, pressure regulating screw, the cavity of one end insertion valve body of valve element, valve casing and valve body
Threaded connection, it is characterised in that：The other end of described valve casing is threadedly coupled with connector, connector threaded connection end cap；Institute
Switch base, spring base I, spring base II, penetration pipe, voltage regulation screw are provided with the valve casing stated, circuit is provided with described connector
Plate；Installation sealing piston seat, piston seat are fixed with gland nut respectively provided with three piston rods in described valve element；Spring base
It is provided with three holes on I, in three spring lever patchholes for being cased with die springs, spring lever corresponds to piston rod close to same respectively
Axis；Described spring base II is connected with Rectangular Spring, and the other end of Rectangular Spring is fixed on voltage regulation screw；Described switch base
Being provided with includes K1, K2, K3 switch, and adjustment switch K1 contacts a spring lever, switchs K2, K3 and another two spring lever is reserved
Gap, K1, K2, K3 are corresponding with spring lever in same axis respectively；Described circuit board is provided with battery, LED I, LED II,
It is fixed on jump ring on connector；Described switch base is fixed on spring base I with adjustment spring, adjusting screw, passes through sheath
Line connects circuit board, and described RVV passes through penetration pipe；Clear glass, observation window are provided with described end cap.
Operation principle：When hydraulic support fluid injection, liquid passes through valve element, piston seat, under the effect of the pressure, three pistons
Bar promotes three spring levers to compress Rectangular Spring.General setting is when reaching just bulging power 90%, on switch base
Switch K1 to open, battery powered, warning LED I is bright；When beyond first bulging power, switch K2 is opened, and LED I is closed；Work as pillar
During beyond rated operating pressure, switch K3 is opened, and warning LED II is bright.This device warns LED during working face use
The bright explanation support setting load of lamp I is low；The bright explanation support plunger shaft superpressure of LED II is warned, plays warning function, it is ensured that working face
Safety in production.
As shown from the above technical solution, the present invention, which has, is less than setting load, cylinder piston chamber superpressure alarm function, under-voltage,
Superpressure pressure value can be set up on request；When warning LED I bright, illustrate that setting load is inadequate, answer timely ftercompction；Warn LED
II it is bright when, illustrate operating pressure superpressure, safety valve failure, answer timely processing, reduce the generation of accident；Hydraulic support, which can be improved, to be made
With the life-span, production cost is saved, improves production efficiency, it is ensured that working face in the pit safety.
