Description
Technical field
The present invention relates to valve field, in particular to a kind of high sealing rotary reversing 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；And the sealability of existing annular plate valve is also not good enough, not only can be there is a situation where leaking, but also can damage
Lose system pressure.
Summary of the invention
Spool Direct Action Type of the existing technology structure of reversing valve is big, poor sealing performance aiming at the problem that, it is of the invention
It is designed to provide a kind of high sealing rotary reversing valve.
To achieve the above object, the technical scheme is that：
A kind of high sealing rotary reversing valve, including valve body, the valve body is interior to be equipped with cylindrical valve chamber, and the valve chamber runs through valve
The top of body, top end of the valve body are equipped with valve deck for blocking valve chamber, uniformly set on the same circumference of valve chamber inner wall there are four with
The through-hole of valve outer wall connection, the valve chamber is interior to be equipped with spool compatible with valve chamber, and the top of spool stretches out valve deck, is located at valve
It is uniformly set on the same circumference of intracavitary spool side wall there are two the arced flow path being spaced apart, each arced flow path is configured to
It can be connected to two through-holes；The spool side wall is equipped with twice annular seal groove, is equipped with ring packing in annular seal groove
Circle, between twice annular seal groove, the spool side wall between two arced flow paths is equipped with axial close the arced flow path
Sealing groove, the both ends of axial seal grooves are connected to twice annular seal groove respectively, and sealing strip is equipped in axial seal grooves.
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.
Preferably, the sealing strip and ring type seal are integrally formed.
Further, the top of the spool is equipped with rotational handle.
Further, dustband is equipped between the valve deck and spool.
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；Twice annular seal groove and its annular sealing
The setting of circle, so that the medium of system will not leak；The setting of two axial seal grooves between two arced flow paths and
The setting of its interior sealing strip so that medium in two arced flow paths will not there is a phenomenon where crossfire, can effectively maintain be
System pressure.

Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
As shown in Figure 1-3, a kind of high sealing rotary reversing valve is set on the top end face of valve body 1 including cylindrical valve body 1
There is the cylindrical valve chamber of indent, 1 top of valve body is equipped with the valve deck 5 for blocking valve chamber, and valve deck 5 is bolted with valve body 1,
Uniformly set on the same circumference of valve chamber inner wall there are four the through-hole 2 that be connected to the outer wall of valve body 1, in valve chamber equipped with and valve chamber phase
The spool 3 of adaptation, spool 3 be it is ladder-like, valve deck 5 is equipped with through-hole compatible with the top of spool 3, and the top of spool 3 is stretched out
Through-hole is located at outside valve body 1, and in order to guarantee that outer wall dust does not enter, the inner wall of through-hole is equipped with annular groove, is provided in annular groove
Dustband 9.
The arced flow path 4 being spaced apart there are two uniformly being set on the same circumference of 3 side wall of spool in valve chamber, often
A arced flow path 4 is configured to be connected to two through-holes 2, and the cross sectional dimensions of arced flow path 4 is equal to the diameter of through-hole 2, arc stream
