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 logical oil groove, valve body on demand
2 commutation hole A, B holes and 1 fuel feed hole P are machined with 1 ' and 1 is returned hole O, joins logical oil groove by moving axially valve element 2 '
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, can produce abrasion between the valve body of valve element 2 ' 1 ' and cause liquid to flow Lou quickly, thus can not 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, can not continuously be worked because using Normal hydraulic reversal valve, can only work and rest for a moment for a moment, have a strong impact on operating efficiency.
Utility model content
The utility model for solve it is set forth above to the problem of, provide a kind of valve element contactless type high frequency direction changing ratio turn for this
Valve, including valve body, valve element, needle bearing, valve body end cap and seal, the valve element are arranged on valve inner, the needle roller axle
Hold and be arranged between valve body and valve element, the valve body end cap is arranged on valve body end positions, and fixes company by screw and valve body
Connect, the valve body and valve element, which are assembled on revolute pair, the valve element, to be provided with distribution and go back to hole, the distribution and go back to hole from end face
Valve inner is extended to, and respectively branches out some hole positions, the sealing ring is arranged on distribution and returns the side position of hole two, the valve element
It is provided with end face outer ring on locating slot, the valve body and is provided with several commutation holes.
Preferably, the commutation hole includes A commutation holes and B commutations hole.
The beneficial effects of the utility model are：The utility model reasonable in design, is rotated by valve element or valve body and realized
Distribution, time hole and commutation hole break-make, realize progress pipeline commutation under the expanding-contracting action of oil cylinder or cylinder, high frequency state, and continuously
Many mechanical efficiency can be greatly improved without rest in work, and the need of high frequency continuous directional valve plant equipment must be applied by meeting
Will.
