Detailed description of the invention
Fig. 1 is a kind of flow shunts valve schematic diagrames such as tiny flow quantity of the present invention.
Specific embodiment
The present invention is further illustrated with attached drawing combined with specific embodiments below.
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Such as Fig. 1 is a kind of embodiment of tiny flow quantity flow shunt valve of the present invention, a kind of flow shunts such as tiny flow quantity
Valve, comprising: valve body 1, the valve body 1 have inlet, are provided at the inlet and wait flow distributors 2, the equal flows
There is valve body fluid path 3, the fluid path with equal flow distributors 2 respectively of valve body fluid path 3 described in two-way in the valve bodies 1 of 2 two sides of distributor
It is connected to, the other end of valve body fluid path 3 described in two-way is connected with the regulating valve seat fluid path 41 of regulating valve seat 4 respectively, described in two
There is spool bore 7 between regulating valve seat 4, be provided with travelling spool 6 in the spool bore 7,7 both ends of spool bore respectively with tune
Section valve seat fluid path 41 is connected, and the 7 bottom both ends of spool bore are respectively arranged with and the perforative first spool fluid path 71 of spool bore 7
With the second spool fluid path 72, the first spool fluid path 71 and the second spool fluid path 72, the travelling spool 6 are split type knot
Structure, respectively includes spool left part and spool right part, and the fit-up gap included between spool left part and spool right part is 0.5-
