Description
Technical field
The utility model relates to the manual 3-position 4-way reversing rotary valve of a kind of end face seal.
Background technique
Hand-operated direction valve is aircraft support equipment and other hydraulic machinery hydraulic services commonly used, and according to the kinematic relation of spool and valve body, hand-operated direction valve has guiding valve and two kinds of forms of rotary valve.The selector valve structure of seeing on the market at present mostly is guiding valve.A kind of two-position four-way rotary valve is arranged in the navigation mark, and this kind rotary valve adopts the cylindrical body spool, by the spool cylinder come on the sealed valve body into and out of hydraulic fluid port, seal form is identical with the guiding valve seal form.This kind two-position four-way rotary valve finds that by producing and test its structural type is high to requirement on machining accuracy, is easy to overproofly, and up-to-standard rate is low, and poor sealing, and internal oil passages is gone here and there oil easily.
Summary of the invention
The purpose of this utility model is to provide the manual 3-position 4-way reversing rotary valve of end face seal of a kind of good airproof performance, economy and durability, easy processing.Technical solution of the present utility model is, rotary valve is made up of upper valve body, following valve body, rotatable handle, running shaft, spring, axle sleeve, seal ring, rotary spool, steel ball, steel ball seat, upper valve body is formed valve body with following valve body, have two center oil throughs and a bottom oil through on the upper valve body, following valve body has an oil through, oil through on the following valve body is communicated with two intercommunicating pores, and two center oil throughs on the upper valve body are corresponding with two intercommunicating pores on the following valve body; Steel ball seat and rotary spool are housed in the valve body, between rotary spool and the steel ball seat steel ball are housed, in two center oil throughs on the upper valve body and two intercommunicating pores on the following valve body axle sleeve, spring are housed respectively, seal ring is socketed on the axle sleeve; Rotatable handle is contained on the running shaft, and running shaft passes the upper valve body center and is connected on the rotary spool.Advantage that the utlity model has and effect,
The utility model adopts a kind of new end face seal form, and just oil through contacts with the rotary spool end face, and the contact of non-traditional cylinder has so just changed traditional form that hole axle quality of fit guarantees the oil circuit sealing of passing through.Have different holes, groove on the rotary spool,, hole on the rotary spool, groove are communicated with oil through on the upper and lower valve body, realize the commutation of hydraulic circuit by rotary spool.In order to guarantee fully contacting of oil through and rotary spool end face, in each oil through axle sleeve is housed, axle sleeve is eliminated contact gap with the rotary spool end face by spring, between axle sleeve and the oil through seal ring is housed, sealing axle sleeve and oil through.
The maximum difference of the structural type of the utility model and guiding valve is: guiding valve by spool the moving axially of valve body, thereby connect, disconnect different oil circuits, the sealing between the oil circuit guarantees by hole axle quality of fit.The utility model is by the rotation of rotary spool in valve body, finishes the commutation of oil circuit, and the sealing between the oil circuit contacts with the rotary spool end face by axle sleeve and guarantees.The utility model valve body adopts split-type structural up and down, is convenient to processing and assembling; Rotary spool adopts the rotating disk form, has effectively reduced the axial size of selector valve; End face seal is adopted in the oil circuit sealing, and uses spring compression, good sealing effect, and spool long service life, and it is convenient to repair behind the end wear; The utility model easy processing, Placement is flexible, can satisfy the usage requirement of some special equipments.
