Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The high-volume hydraulic that is applicable to energy-storing workover rig described in the utility model is controlled formula duplex reversing slide valve, by two two position three way directional control valve stack combinations shared same valve body 1; Specifically, comprise valve body 1 and two two position three-way valves; Two two position three-way valves are up and down, are arranged in valve body 1 to axis horizontal, and the axis of two two position three-way valves is in same vertical plane.A upper two position three-way valve includes piston 2-3, pilot port flange 2-1 and 2-2, the be placed in both sides of valve body 1 of two pilot port flange 2-1 and 2-2, and being respectively equipped with guide's filler opening Xa and guide's oil return import Ya, piston 2-3 is placed in the valve body between two guide's flange 2-1 and 2-2; The going out of this two position three-way valve offers oil outlet A on oil pocket A5 and valve body 1 and interlinks.Next two position three-way valve includes piston 3-3, pilot port flange 3-1 and 3-2, itself and a upper two position three-way valve are up and down layout accordingly, two pilot port flange 3-1 and 3-2 are respectively equipped with guide's filler opening Xb and guide's oil return import Yb, and the going out of this two position three-way valve offers oil outlet B on oil pocket B5 and valve body 1 and interlink.The drainback passage A3 of a upper two position three-way valve and oil inlet passage A4 interlink with drainback passage B3 and the oil inlet passage B4 of next only upper two position three-way valve respectively, and the oil inlet P of offering on oil inlet passage A4 and valve body interlinks, the oil return inlet T that oil inlet passage B4 and valve body are offered interlinks.On valve body 1, offer the auxiliary oil inlet P 1 interlinking with oil inlet passage A4.
During work, oil inlet P of the present utility model is connected with oil return inlet T with other oil inlet P a plurality of of the present utility model with oil return inlet T, forms oil supply system; Auxiliary oil inlet P 1, guide's filler opening Xa, Xb are connected with oil feed pump with guide's oil return import Ya, Yb; Oil outlet A is connected without device with the hydraulic pressure of energy-storing workover rig with B.
When the upper two position three-way valve fuel feeding of needs, first, to guide's filler opening Xa fuel feeding, hydraulic oil fills up guide's oil suction chamber A1 chamber, promotes piston 2-3 and arrives valve body 1 right-hand member, now go out oil pocket A5 and communicate with oil inlet passage A4, and oil inlet passage A4 and oil return inlet T is obstructed; Then, to auxiliary oil inlet P 1 fuel feeding, hydraulic oil is through oil inlet passage A4 and go out oil pocket A5, exports the hydraulic element of energy-storing workover rig from oil outlet A to.And when the upper two position three-way valve fuel feeding commutation of needs, first to guide's oil return filler opening Ya fuel feeding, hydraulic oil fills up guide's oil suction chamber A2 chamber, promotes piston 2-3 and arrives valve body 1 left end, now go out oil pocket A5 and communicate with drainback passage A3, and oil inlet passage A4 and auxiliary oil inlet P 1 are obstructed; Then, oil return inlet T fuel feeding, hydraulic oil is through drainback passage A3 and go out oil pocket A5, exports the hydraulic element of energy-storing workover rig from oil outlet A to.
When next two position three-way valve fuel feeding of needs, first, to guide's filler opening Xb fuel feeding, hydraulic oil fills up guide's oil suction chamber B1 chamber, promotes piston 3-3 and arrives valve body 1 right-hand member, now go out oil pocket B5 and communicate with oil inlet passage B4, and oil inlet passage B4 and oil return inlet T is obstructed; Then, to auxiliary oil inlet P 1 fuel feeding, hydraulic oil is through oil inlet passage B4 and go out oil pocket B5, exports the hydraulic element of energy-storing workover rig from oil outlet B to.And when next two position three-way valve fuel feeding commutation of needs, first to guide's oil return filler opening Yb fuel feeding, hydraulic oil fills up guide's oil suction chamber B2 chamber, promotes piston 3-3 and arrives valve body 1 left end, now go out oil pocket B5 and communicate with drainback passage B3, and oil inlet passage B4 and auxiliary oil inlet P 1 are obstructed; Then, oil return inlet T fuel feeding, hydraulic oil is through drainback passage B3 and go out oil pocket B5, exports the hydraulic element of energy-storing workover rig from oil outlet B to.
When the hydraulic system of energy-storing workover rig need large flow, while commutating fast, upper and lower two two position three-way valves are worked simultaneously.
