In valve body 1 ', valve element 2 ' can be along the endoporus axis direction linear reciprocating motion of valve body 1 ', and valve element 2 ' processes on demand logical oil groove, valve body
2 commutation hole A, B holes and 1 fuel feed hole P are machined with 1 ' and 1 is returned hole O, by moving axially valve element 2 ' logical oil groove connection is made
Oilhole on logical or cut-off valve body 1 ', reaches the purpose of liquid stream commutation；But this traditional valve core of hydraulic reversing valve 2 ' is axially past
There is inertia force when commutating again, inertia force causes greatly vibration when commutating at a high speed, while there is machinery between valve element 2 ' and valve body 2 '
Friction, high-speed and continuous commutation, abrasion can be produced between the valve body of valve element 2 ' 1 ' quickly and cause liquid to flow Lou, thus cannot high frequency it is continuous
Commutation, actually many plant equipment need high frequency continuous hydraulic reversal valve, for example：High power hydraulic jump bit, hydraulic pile
Machine, because cannot continuously being worked using Normal hydraulic reversal valve, can only work and resting for a moment for a moment, have a strong impact on operating efficiency.
The content of the invention
The present invention for solve the problems, such as it is set forth above arrive, provide a kind of valve element contactless type high frequency direction changing ratio rotary valve for this,
Including valve body, valve element, needle bearing, valve body end cap and seal, the valve element is arranged on valve inner, and the needle bearing sets
Put between valve body and valve element, the valve body end cap is arranged on valve body end positions, and is fixedly connected with the valve body by screw, institute
State valve body and valve element is assembled into and rotates secondary, distribution is provided with the valve element and hole is gone back to, the distribution extends with time hole from end face
To valve inner, and some hole positions are respectively branched out, the sealing ring is arranged on distribution and returns the side position of hole two, the spool end
Locating slot is provided with outer ring, several commutation holes are provided with the valve body.
Preferably, the commutation hole includes A commutation holes and B commutations hole.
The invention has the beneficial effects as follows：Present configuration is reasonable in design, is rotated by valve element or valve body and realizes distribution, Hui Kong
With commutation hole break-make, realize carrying out pipeline commutation under the expanding-contracting action of oil cylinder or cylinder, high frequency state, and continuously work and need not stop
Breath, can be greatly improved the efficiency of many machineries, and meeting must apply the needs of high frequency continuous directional valve plant equipment.
