Description
Technical field
The utility model relates to the emulsion power pack of underground coal mine support system.
Background technique
In underground coal mine hydraulic prop system, emulsion power pack is needed to produce hydraulic power.Current emulsion power pack has pneumatic type and electrodynamic type.No matter pneumatic type or electrodynamic type, be all at least be provided with emulsion tank, break pressure cistern, water pump, oil pump, power engine and combinaing valve body on chassis; Wherein the power engine of pneumatic type is pneumatic pump, and DYN dynamic power engine is motor-drive pump, is also provided with the float valve of automatic feeding water in break pressure cistern.At work, will need autostop when pumping plant reaches rated working pressure, when autostop no longer needs to supply water easily there is spilling water phenomenon in break pressure cistern, namely affects subsurface environment, waste water source again; Analyze reason; mainly hundreds of rice in down-hole is dark; tap water pressure from ground is far longer than the pressure (but being less than pumping plant working pressure) of break pressure cistern float valve, and pumping plant shuts down float valve when no longer needing to supply water and can not automatically cut out, and causes break pressure cistern generation spilling water.
Model utility content
The purpose of this utility model overcomes the deficiencies in the prior art, proposes a kind of Emulation Concentration in Coal Mine movable pump station with overflow-proof function.
Have an Emulation Concentration in Coal Mine movable pump station for overflow-proof function, it is on chassis, be provided with emulsion tank, break pressure cistern, water pump, oil pump, one-way valve and combinaing valve body; In break pressure cistern, be wherein also provided with the float valve of automatic feeding water, it is characterized in that, it also comprises a water stopping valve be connected on float valve water intake, and the pressure duct of this pumping plant connects a threeway again; The structure of water stopping valve is, comprises a valve body, is provided with upper and lower chamber in valve body, is provided with higher than tap water intake pressure and lower than the pressure spring of pumping plant rated working pressure, be provided with the piston rod that seal ring is housed in cavity of resorption, piston rod withstands on pressure spring in epicoele; The top of epicoele is provided with the water inlet interface be connected with running water pipe, and the side of epicoele is provided with the tap water be connected with float valve and exports, and the bottom of cavity of resorption is provided with and is connected high pressure liquid import with threeway; When pumping plant reaches rated working pressure shutdown; hydraulic pressure in pressure duct enters water stopping valve cavity of resorption by threeway, and promotion piston rod overcomes pressure spring resistance and moves up, and blocks the tap water outlet of epicoele; thus cut off the tap water entering float valve, prevent break pressure cistern generation spilling water.
In order to prevent too tight by pressure spring top of piston rod, be provided with step or pin in the epicoele of water stopping valve valve body, step or pin play position-limiting action to piston rod.
The utility model utilizes the pressure of pumping plant self to solve the hydraulic overflow problem of break pressure cistern dexterously, namely protects subsurface environment, again saves nervous water resources.
