Generally adopt hydraulic prop to control mine roof pressure, particularly hydraulic prop under the mine, more extensive in the colliery down-hole application.The turnover of liquid in the hydraulic prop, the removal of a column load, the measurement of roof pressure, and safeguard protection all must be installed various valves on hydraulic prop, and instrument is measured and is controlled, and grasps the ore deposit and presses Changing Pattern, the prevention roof accident.The domestic and international at present device that adopts, advanced is hydraulic prop pressure measurement triple-use valve, it is by feed liquor one way valve, safety valve, pressure measurement one way valve, the composite set that pressure meter and feather valve are formed.But the safety valve in the existing pressure measurement triple-use valve; all be to adopt plate armature; its spillway discharge maximum has only 3 liters/minute; in the Coal Production process; the down-hole top board is usually pressed very big suddenly; or other shock loading appears; though action time is extremely short; but top board can sink rapidly, contract under the post of living and the instantaneous lifting rate that forms is very big, and the flat safety valve in the existing pressure measurement triple-use valve just has little time discharge opeing; can't fast discharging; cause the pillar bending, even post takes place, do not have the effect of safeguard protection.Simultaneously at safety valve and feather valve; in the structure that liquid-filling valve connects; the shaft structural strength of long connecting screw rod too a little less than; often fractureed, damaged, cause pressure measurement triple-use valve self in addition part very easily damage, bear top board high pressure or when meeting other impact type load suddenly when pillar especially; the fluid pressure that row does not go out heightens; the pressure that acts on each other part of triple-use valve overloads greatly, causes the interior long connecting screw rod of triple-use valve very easily to damage, and does not have the safeguard protection effect.
In order to overcome the shortcoming of existing pressure measurement triple-use valve; must redesign from the structure of safety valve and link thereof; make safety valve increase intensity of spillway discharge and each other part of reinforcement; satisfy the mine hydraulic prop and can Enough bear the mine top board suddenly under high pressure or other impact loading, can play the safeguard protection effect.That is to say, make the pressure measurement triple-use valve can have big spillway discharge of sufficient Enough and intensity, when pillar bears big dynamic overload, can still play the safeguard protection effect firmly, reliably.Counted the big flow pressure measurement of the utility model triple-use valve for above-mentioned purpose is ad hoc.For providing a kind of safe, reliably under the coal mine, be applicable on the hydraulic prop fluid injection, pressure measurement, unloading, the good three-in-one unit of safeguard protection performance.
The technology of big flow pressure measurement triple-use valve constitutes, the composite set of being made up of fluid injection one way valve, feather valve, safety valve, pressure measurement one way valve and pressure meter.The valve core structure of this safety valve makes the slide-valve plunger pattern into by original plate armature, maximum spillway discharge expands 16 liters/minute to by original 3 liters/minute, the shaft of the long connecting screw rod that is connected with feather valve, fluid injection one way valve on the safety valve can extend, increase the intensity of connecting screw rod, strengthened the reliability of triple-use valve self.Make original consumable accessory become firm part, the also corresponding lengthening of overflow ducts when also impelling simultaneously the hydraulic prop overload.The safety valve of this slide-valve plunger pattern; be with the sealing of side direction " O " type rubber seal between spool and the valve seat; one end of spool has several (being generally 8) radial holes; penetrate the spool wall; when top board promotes spool suddenly during high pressure; after making the end that radial hole is arranged in the spool surpass sealing ring; Gao hydraulic fluid Ti Calipering flows out from spool wall several apertures on every side; spillway discharge can reach in the discharge orifice that 16 liters of/minute Calipering can open rapidly in some seconds; discharging is big spillway discharge so, in the time that can extremely lack the energy of shock loading is dropped to rapidly in the limit that hydraulic prop can bear, and plays the effect that the pillar dynamic overload is protected.Behind impact type dynamic loading removal, can prevent to produce in the hydraulic system vibration, and can Li Calipering closed safe valve; thereby restriction continues to fall post; make pillar and top board keep excellent contact, really pillar is control effectively and overload protective function, protection pillar not reason overloads and is damaged.
The largest benefit of big flow pressure measurement triple-use valve; be exactly that spillway discharge is big, the intensity height is applicable under the coal mine under the harsh environmental conditions; hydraulic prop is carried out fluid injection, pressure measurement, unloading start to control making usefulness, and high pressure and other shock loading play the safeguard protection effect suddenly to top board.It is the triple-use valve valve combining device that hydraulic prop is most economical under the coal mine, performance good, function is many.
Accompanying drawing 1 is the structure general assembly drawing of big flow pressure measurement triple-use valve.
Accompanying drawing 2 is a part partial enlarged drawing in addition such as safe spool and valve seat in the big flow pressure measurement triple-use valve.
