Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification,
The basic structure of the present invention is described the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
As shown in Figure 1-2, change-over valve core two-stage hydraulic control structure of the present invention, including commutation valve body (1) and set
Put the reversing valve core 2 in commutation valve body 1.Commutation valve body 1 two ends are provided with the first end cap 3 and the second end cap 4,
Having this connection guide's oilhole one 3-K2 on first end cap 3, on the second end cap, 4 have this connection guide's oilhole two 4-
K1.Commutation valve body 1 has other connection guide oilhole 1-K1 near the side of the first end cap 3.
Being provided with spring base 5, ring 6 and spring, spring base 5 and ring 6 in first end cap 3 can be at the first end cap 3
Interior slip, spring base 5 one end is connected with reversing valve core 2, and the other end is connected with spring in stretching into ring 6, institute
The spring stated passes in the ring of described ring 6 and is fixed on the inwall of the first end cap 3, the cylindrical table of ring 6
Face and the groove on the inwall of the first end cap 3 form the first cavity volume 3-R1 and the second cavity volume 3-R2 sealed.
Set up and connecting of intercepting the first cavity volume 3-R1 and the second cavity volume 3-R2 as it is shown on figure 3, have on ring 6
Groove 6-C, groove 6-C be oval-shaped slot, groove 6-C has 4 and circumference is distributed on ring 6, the first end cap 3
On have a runner hole 3-K1,3-K1 one end, runner hole connect with other connection guide oilhole 1-K1, the other end and
First cavity volume 3-R1 connection.
Spring base 5 has near one end of reversing valve core 1 and prevents spring base 5 from all stretching into the flange collar one in ring 6
7, on ring 6, the one end near spring base 5 has flange collar 28.
Operation principle: when on the second end cap 4 of reversing valve core 2, this connection guide's oilhole two 4-K1 is passed through first drain
During force feed, reversing valve core 2 moves right together with spring base 5, when acting surface 5-A contact on spring base 5
First acting surface 6-A1 on ring 6, band rotating ring 6 moves right together, is at this moment used on ring 6 introducing other connection
4 symmetrical shallow slot 6-C of guide oil can open, the first cavity volume 3-R1 on the first end cap and the second cavity volume 3-R2
Connection, i.e. can introduce other connection guide oils and pass through the first cavity volume 3-R1 to second cavity volume 3-R2 on the first end cap,
The pressure of other connection guide oils acts on the second acting surface 6-A2 on ring 6, and ring 6 can be joined guide by other
Oil to ring 6 active force to the left, then final reversing valve core 2 can this connection guide oil active force to the right and its
He join guide oil active force to the left make a concerted effort under keep balance, eventually settle out.
