Abstract
The utility model belongs to a hydraulic controlling device, which concretely relates to a three-position five-way fluid control rotary valve used in the hydraulic controlling device of a log splitter. The utility model is characterized in that: one side of a through hole of a valve body is equipped with a rotary valve, and the other side is equipped with a one-way valve. The rotary valve consists of a rotary valve sleeve of a valve cover and a slide valve core of the rotary valve sleeve; the one-way valve consists of a spring plugged and blocked in a chamber of the valve body and a steel ball matched with an oil inlet and an oil outlet. Three actions of forwarding, backing and stopping of an oil cylinder, which obtains three-position control, and avoids that there has need of adding a protection apparatus on a two-position five-way rotary valve to prevent wrong actions of an operation. The hydraulic controlling device has the advantages of safety, reliability, long service life and low manufacturing cost.
Description
Technical field: the utility model belongs to hydraulic control device, is specifically related to a kind of three-position five-way pilot operated rotary valve of using at the wood splitting machine hydraulic control device.
Background technique: at present, the hydrovalve that horizontal splitter uses adopts guiding valve and two-position five-way hydraulic reversing valve more, and its shortcoming is that the spool of guiding valve blocks at pressure Gao Shiyi, and the life-span is short; And the two-position five-way hydraulic reversing valve, though overcome above-mentioned shortcoming, it because the operating handle spacing is too small, needs to increase protective equipment in actual use, reduces operational misoperation, has the high defective of manufacture cost.
Summary of the invention: the purpose of this utility model provides the three-position five-way pilot operated rotary valve of long, low cost of manufacture of a kind of safe and reliable, life-span.
The technical solution of the utility model is: a kind of three-position five-way pilot operated rotary valve, on valve body, establish oil pump oil inlet hole, oil pump oil sump tank hole, oil cylinder oil inlet hole and oil cylinder spill port, the oil sump tank hole; Between oil pump oil inlet hole and oil sump tank hole, establish relief valve; It is characterized in that: a side is established rotary valve in the through hole of valve body, and opposite side is established one-way valve.Wherein, described rotary valve is made up of the sliding spool in rotary valve housing in the valve pocket and the rotary valve housing; Establish handle on the rotary valve housing, valve body is stretched out by the limited cap mesopore in the handle outer end, is provided with Returnning spring between sliding spool one end and the rotary valve housing; The other end and one-way valve join; Valve pocket and rotary valve housing corresponding position be provided with through hole respectively with valve body on the corresponding connection in oil sump tank hole, oil pump oil sump tank hole; The oil cylinder spill port is provided with through hole by valve pocket and rotary valve housing corresponding position and is communicated with the rotary valve housing cavity; The oil pump oil inlet hole is communicated with the oil cylinder oil inlet hole; Be provided with annular groove with oil cylinder spill port corresponding position on the valve pocket cylindrical; Be provided with annular groove with the through hole corresponding position on the valve sleeving inner wall.Described one-way valve is to be closed in the spring in the valve body cavity and to be constituted with the steel ball that matches into and out of oilhole by plug, and oil outlet is positioned at the annular groove on the valve body.
Owing to adopt technique scheme, in the forward and back of oil cylinder, stop three actions and realized three controls, avoided needing to increase protective equipment on the two-position five-way rotary valve and prevent operational misoperation, have safe and reliable, the life-span long, advantage of low manufacturing cost.
Description of drawings: the technical solution of the utility model is described in further details below in conjunction with the drawings and specific embodiments.Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A---A sectional view of Fig. 1, and Fig. 3 is the B-B sectional view of Fig. 1, and Fig. 4 is the C-C sectional view of Fig. 1.
