Description
Technical field
The present invention relates to valve field, in particular to a kind of rotational positioning reversal valve.
Background technique
Reversal valve is a kind of for switching the valve of fluid flow direction, is widely used in liquid gas pressure field；But it is existing
The spool of reversal valve is mostly Direct Action Type, and the reversal valve of this structure is unfavorable for system there are the structure of spool and valve body is larger
The shortcomings that miniaturization；Meanwhile the spool of existing reversal valve does not have locking structure, this be easy to cause spool in use process being situated between
It is voluntarily acted under matter effect, leads to the system failure.
Summary of the invention
For the big problem of the structure of reversing valve of spool Direct Action Type of the existing technology, the purpose of the present invention is to provide
A kind of rotational positioning reversal valve.
To achieve the above object, the technical solution of the present invention is as follows:
The top surface of a kind of rotational positioning reversal valve, including valve body, the valve body is equipped with the cylindrical valve chamber of indent, valve body
Top is removably connected with valve deck, uniformly sets on the same circumference of the valve chamber inner wall logical there are four what is be connected to valve outer wall
Hole, the valve chamber is interior to be equipped with spool compatible with valve chamber, and the valve deck is equipped with through-hole compatible with spool, the top of spool
It stretches out outside through-hole to valve body, uniformly sets that there are two the arcs that are spaced apart on the same circumference of the spool side wall in valve chamber
Runner, each arced flow path are configured to and two through-hole faces；The spool is equipped with locking device, and the locking device is used for
Spool is locked when through-hole is connected to arced flow path.
Preferably, the cross sectional dimensions of the arced flow path is equal to the diameter of through-hole.
Preferably, the cross section of the arced flow path is semicircle.
Further, the inner wall of the through-hole is equipped with annular seal groove, is equipped with ring type seal in annular seal groove.
Preferably, the locking device includes the cross bar being hinged on the top of the spool and is uniformly arranged on valve deck top
Four on the same circumference in face are used to accommodate the groove of the cross bar other end.
Preferably, there are two the cross bar is set, two cross bars are symmetrically hinged on the two sides of spool.
Another preferred, the locking device includes the spring catch being arranged on valve deck top surface and is uniformly arranged on spool
Four pin holes on the same circumference of outer wall, the spring catch is perpendicular to valve core axis.
Preferably, there are two the spring catch is set, two spring catch are symmetrically arranged on the valve deck of spool two sides.
By adopting the above technical scheme, due to the through-hole on valve chamber inner wall, the arced flow path being spaced apart in spool outer wall
Setting so that spool, when rotating to a position, a certain through-hole is connected to adjacent through-hole by arced flow path, then is rotated
At 45 °, a certain through-hole can be connected to the through-hole adjacent with another volume by arced flow path again and be connected to, and realize the commutation of two-position four-way
Structure；The present invention has the characteristics that small in size, commutation stroke is small, commutation is quick；The setting of locking device, so that reversal valve makes
Used time, spool will not malfunction under the action of medium.
