Technical field
The utility model relates to a kind of technology of hydro-pneumatic field, specifically a kind of general rotary valve reversal valve.
Background technology
Current reversal valve is to be divided into spool-type valves, rotary valve according to the switch forms of fluid path or gas circuit difference
Reversal valve, ball-valve type reversal valve and cone valve type reversal valve.Reversal valve is the relative motion with spool and valve body, and oil circuit is made to connect
The direction of logical, shutdown or transformation oil stream, to realize the startup, stopping or change of hydraulic pressure or pneumatic apparatus and its driving mechanism
Change the Important Components of the direction of motion.The structure of traditional reversal valve is higher but interior to the requirement on machining accuracy of each component of valve
Portion's leakage problem happens occasionally, this just gives one to bring difficulty to the multidirectional valve body structure arrangement of multidirectional or multidirectional switching is switched.
Utility model content
The utility model is directed to deficiencies of the prior art, proposes a kind of general rotary valve reversal valve, structure
Simply, easily manufactured, it can be achieved that interface generalization and standardization.
The utility model is achieved through the following technical solutions：
The utility model includes：Spool, valve body and spool location structure, wherein：Spool and valve body coaxial arrangement, spool are fixed
Bit architecture is set in the hole that valve body is radially beaten and is in contact with the locating slot on spool.
The outer surface of the spool is equipped with taper inclined-plane, which is provided with the ditch to match with the bore of to be switched pipeline
Slot, at least provided with one group of radial duct and with axial semi-enclosed hole link.
The tail portion of the spool is equipped with manually rotated handle, and head is equipped with locking nut.
The spool location structure includes：Fixing screws, spring and positioning ball, wherein：The bottom of positioning ball is convex
It is contacted for valve body and with the locating slot on spool, spring is located at the top of positioning ball, and fixing screws are set to the upper of spring
Side.
Technique effect
Compared with prior art, it is multidirectional to multidirectional or multidirectional switching is switched can to design one according to actual needs for the utility model
Reversal valve, while can ensure its sealing effect.

2 inner surface of valve body is equipped with taper inclined-plane and taper is identical as the taper of the outer surface of spool 1.
Duct 103 of the surface of the valve body 2 equipped with radial direction is simultaneously corresponding with the groove of spool 1 102.
The spool location structure 3 includes：Fixing screws 301, spring 302 and positioning ball 303, wherein：Position steel
The bottom of pearl 303 protrudes from valve body 2 and is contacted with the locating slot 101 on spool 1, and spring 302 is located at the top of positioning ball 303
Portion, fixing screws 301 are set to the top of spring 302.
Said mechanism works in the following manner：
Pipeline will be output and input when use to be respectively connected at 2 corresponding duct of spool 1 and valve body, rotary spool 1 to finger
Determine operating position, and ensure that 1 position of spool is correct by spool location structure 3, tightens locking nut 6 and ensure non-access sealing,
Hereafter it connects oil circuit or gas circuit is started to work.When commutation, oil circuit or gas circuit are closed, locking nut 6, rotary spool 1 to finger are unscrewed
Determine operating position, and ensure that 1 position of spool is correct by spool location structure 3, tightens locking nut 6 and ensure non-access sealing,
Hereafter it connects oil circuit or gas circuit is started to work.
Above-mentioned specific implementation can by those skilled in the art under the premise of without departing substantially from the utility model principle and objective with
Different modes carries out it local directed complete set, and the scope of protection of the utility model is subject to claims and not by above-mentioned specific
Implementation is limited, and each implementation within its scope is by the constraint of the utility model.
