Description
Technical field
The utility model relates to hydrovalve technical field, particularly relates to a kind of sliding type selector valve.
Background technique
Hydrovalve is the Automation Elements of a kind of pressure oil operation, and it is by the control of voltage distribution valve pressure oil, and usual and electromagnetic distributing valve combinationally uses, and can be used for the break-make of distant control water power plant oil, gas, water piping system.Be usually used in the oil circuits such as clamping, control, lubrication.
Hydrovalve is the control unit in hydraulic system, and its function is the flow direction of liquid in hydraulic control system, pressure and flow, with make the operation mechanism of hydraulic actuator and driving thereof obtain required for moving direction, movement velocity and thrust etc.
Gap between the spool of sliding hydraulic valve and valve opening is very little, when guiding valve pair has error in geometrical form (foozle) and concentricity (positional error), spool will be subject to the effect of lateral hydraulic force due to radial hydraulic pressure skewness, spool is subject to the effect of lateral hydraulic force, make the throw of eccentric between spool and valve opening increasing, until surface both contact, at this moment lateral hydraulic force reaches maximum, can spool jam be made like this, affect the normal use of valve.
Model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of sliding type selector valve, can reduce the selector valve hydraulic coupling problem because error in geometrical form and concentricity cause, prevent spool jam.
The utility model is achieved through the following technical solutions:
A kind of sliding type selector valve, comprise selector valve housing, columned valve body hole is offered along its axial direction in described selector valve housing, columned spool is slidably fitted with in described valve body hole, spool can slidably reciprocate along the centerline direction of valve body hole, and leave gap between the outer wall of described spool and the inwall of valve body hole, the external cylindrical surface of described spool is provided with multiple cylinder ring, and described cylinder ring is evenly arranged on spool, the outer diameter of cylinder ring is greater than the diameter of spool, and elasitic layer is provided with on the external cylindrical surface of cylinder ring, described elasitic layer is curved along extending radially outwardly of cylinder ring.
As optimal technical scheme of the present utility model, the quantity of described cylinder ring is even number, when liquid flows through the gap between spool and valve body hole, and the mutual counteract of the instantaneous hydraulic dynamics that it can be made to produce, improve the stability of spool in valve body hole, reduce noise and vibration.
As optimal technical scheme of the present utility model, the quantity of described cylinder ring is eight, and the distance between adjacent cylinder ring is equal.
As optimal technical scheme of the present utility model, described elasitic layer is bonded in the outer surface of cylinder ring by adhesive.
As optimal technical scheme of the present utility model, described elasitic layer adopts polyurethane material to make, and its maximum ga(u)ge is 0.85mm.
As optimal technical scheme of the present utility model, the shaft axis of described spool and valve body hole is located on the same line.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by being provided with cylinder ring, the selector valve hydraulic coupling problem because error in geometrical form and concentricity cause can be reduced, by being provided with elasitic layer, improve its frictional behaviour on the one hand, prevent spool jam on the other hand, strengthen the using effect of spool.
