Description
Technical field
The utility model is related to a kind of pressure-reducing valve, refers in particular to a kind of emulsification for coal mine fully-mechanized mining working hydraulic support
Liquid pressure-reducing valve.
Background technology
It is medium that existing pressure-reducing valve is mainly suitable for hydraulic oil, for the decompression with emulsion as working media for the colliery
The valve also not better suited product of ratio, the pressure-reducing valve used by fully-mechanized mining working is mainly used in pressure requirements than relatively low gateway belt
The effects such as the tensioning of the machinery such as wheel, scratch board machine chain, coal-winning machine, elevating conveyor, cooling.
Chinese patent once disclosed a kind of Double-mouth direct-action (200720195809.X), by housing, valve element, valve element
Set, locking nut, spring, inlet, the Double-mouth direct-action of liquid outlet composition.Significantly expand many low pressure tool-class to produce
The instruments such as range in high-pressure system for the product, such as emulsion boring machine, emulsion saw, emulsion spanner are in down-hole emulsion
Usage amount in system will greatly increase, and improve the energy utilization efficiency of high-pressure system, in particular improve coal mine inferior
The mechanized operation level of harsh environments.
Utility model content
The purpose of this utility model is to provide a kind of emulsion pressure-reducing valve, its compact conformation, long service life, output
Pressure stability, output pressure can adjust.
For reaching above-mentioned purpose, the solution that the utility model is taken is：A kind of emulsion pressure-reducing valve, in main valve body
Offer valve pocket and P mouth and O mouth, valve pocket, built with main valve plug and spring, has damping hole, main valve plug and main valve body in main valve plug
Formed liquid gap, equal about the sealing area of main valve plug；Guide's valve pocket is had on guide valve blocks, fills successively in guide's valve pocket
Enter valve seat, pilot valve, guide's spring, spring base, screw plug is screwed into guide's valve pocket and is contacted with valve seat, swivel nut and guide valve blocks screw thread
Connect, adjusting screw rod is screwed into big nut and is contacted with spring base with swivel nut, and handwheel primary nut is fixed on above adjusting screw rod, guide
Spring one end props up spring base, the other end props up pilot valve, and the conical surface of pilot valve forms conical surface hard sealing structure with valve seat,
Guide valve blocks are provided with the leakage opening of drainage；Spring one end props up main valve plug, the other end props up guide valve blocks；Cover plate, main valve
Body and guide valve blocks, make three be fastenedly connected by the screwed hole bolt at main valve body two ends.
The utility model compared with prior art, has the advantages that：When to P confession liquid, liquid is through main valve body
Flow into O mouth with the liquid gap of crossing that main valve plug is formed, flow into guide's valve pocket through damping hole on main valve plug, set when O mouth pressure is more than
Pilot valve in guide's valve pocket during value overcomes guide's spring force and frictional force, liquid through the liquid pass hole in valve seat, from leakage opening
Flow out, due to equal about the sealing area of main valve plug, the pressure that pilot valve is opened on the right side of rear main valve plug is less than the pressure in left side
Power, main valve plug overcomes spring and hydraulic coupling to move right, and the liquid gap of crossing that now main valve plug and main valve body are formed diminishes, and pressure damages
Lose and become big, the pressure drop of O mouth, reach setting value.It has compact conformation, long service life, and output pressure is stable, output pressure
The features such as power can adjust.
