Detailed description of the invention
As Figure 1-4, this utility model one hydraulic control one-way valve, including: valve body 1；Valve body 1 include oil-in 11,12,
Oil-out 14 and control port 13.(spiral assembling or clamping) fast patch plug is installed at oil-out 14.Fast patch plug
Including left chamber 23, right chamber 24 and spool 3, wherein the right chamber 24 of fast patch plug is connected with oil-in 11,12.Spool 3
Run through left chamber 23 and the right chamber 24 of fast patch plug, and spool right-hand member stretches out to the right right chamber 24.Spool is hollow structure, and spool
On have connection valve core cavity, the aperture in the left chamber of fast patch plug；Valve core cavity is connected with fast patch plug oil-out to the left simultaneously.
Additionally between left chamber 23 and right chamber 24, it is provided with valve seat 25, coordinates with the flap with spool.Spool 3 include standard-sized sheet station and
Fully closed station, when spool is in standard-sized sheet station, the flap of spool 3 separates with valve seat 25, the left chamber 23 of fast patch plug and the right side
Chamber 24 is connected；When spool 3 is in fully closed station, the flap of spool 3 and valve seat 25 formed sealing pair (conical surface seal or
Ball face sealing), left chamber 23 and the right chamber 24 of fast patch plug are isolated from each other.
Being provided with mobile piston 4 in the oil-out 14 of valve body 1, on the right side of fast patch plug, mobile piston 4 is by control port 13
Completely isolated with oil-out 14；Mobile piston 4 includes left station and right working position, and when mobile piston 4 is in left station, it will
Spool 3 pushes standard-sized sheet station to；When mobile piston 4 is in right working position, spool 3 is affected by oil pressure at oil-in 11,12
Switch between standard-sized sheet station, fully closed station.
Further, fast patch plug includes end to end plug body 21 and fixed piston 22；Wherein plug body 21 is interior
Chamber forms left chamber 23, and the inner chamber of fixed piston 22 forms right chamber 24.Why fast patch plug is designed to plug body 21 with solid
The assembly of fixed piston 22, it is therefore intended that: the 1. convenient installation to spool 3 and maintenance；2. fixed piston 22 is fuel-displaced with valve body
Sealed environment is formed, it is to avoid hydraulic oil is revealed, and then ensure that fast patch plug fastness at oil-out 14 between mouth 14.
The operation principle of a kind of hydraulic control one-way valve of this utility model is as follows:
When at control port 13, no pressure oil is connected, hydraulic oil flows into fast patch plug from the first oil-in 11/ second oil-in 12
Right chamber 24: 1. when enter right chamber 24 oil pressure be insufficient to big time, then spool 3 is in fully closed station, as shown in Figure 1；2. when
Enter the oil pressure in right chamber 24 sufficiently large time, then spool 3 is moved to the left standard-sized sheet station, and hydraulic oil flows into the left chamber of fast patch plug
23, and then after valve core cavity and fast patch plug oil-out, flow out valve body successively, as shown in Figure 2；
When having pressure oil to connect at control port 13, pressure oil promotes mobile piston 4 to move to left station to the left, then moves
Piston 4 promotes spool right-hand member to make spool 3 be moved to the left standard-sized sheet station, thus valve port is opened, the most no matter oil-in 11,
Oil pressure at 12 has much, and hydraulic oil homomergic flow enters the left chamber of fast patch plug, and then successively through valve core cavity and fast patch plug oil-out
Rear outflow valve body, as shown in Figure 3.
Embodiment described above is only to be described preferred implementation of the present utility model, not to of the present utility model
Scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this utility model
The various deformation made of technical scheme and improvement, all should fall in the protection domain that this utility model claims determine.
