Described upper valve body (1a) has vertically the through hole of a 3 stops, the large footpath section of upper and lower part is center hole section, the path section at middle part is eccentric opening section, and the large footpath section on top is equipped with one piece of described filter screen (2), the outward edge of this filter screen embeds in the annular mounting groove bottom the section of large footpath; A seal ring (3) is embedded with at the bottom of the large footpath sector hole of described upper valve body (1a) through hole bottom, sealing circle is positioned at outside the path section of upper valve body (1a) through hole, and the underpart of this large footpath section has an annular spacing groove;
The path section on described lower valve body (1b) top is inserted in the large footpath section of upper valve body (1a) through hole bottom, the annular stop boss of this insertion part (1b " ') snaps in the annular spacing groove of this large footpath section; and lower valve body (1b) upper-end surface and described seal ring (3) bottom surface are close to, and the path section of upper valve body (1a) through hole can be communicated with wherein metering hole described in any one (1b ') simultaneously in metering hole described in any one (1b ') be communicated with.
During use, lower valve body (1b) and upper valve body (1a) can be relatively rotated, thus allow the path section of lower valve body (1b) through hole and different metering hole (1b ') be communicated with, so just can change and control flow, thus make this Proportional valve have the function of adjust flux, and then overcome conventional construction because can not regulable control flow and need the defect of plurality of specifications Proportional valve for subsequent use, and the utility model just solves large problem by little change, there is good practicability.And, because lower valve body (1b) and upper valve body (1a) are connected by annular stop boss (1b " '); axial displacement can not occur when these two valve bodies relatively rotate; so just can ensure sealing well; thus very effectively avoid the path section of lower valve body (1b) through hole to be communicated with two metering holes (1b ') simultaneously, so just can ensure normal work of the present utility model.
As optimizing design scheme, the number of described metering hole (1b ') is 4, and its number is moderate.
For the ease of connecting lower valve body (1b) and upper valve body (1a), the end face of described annular stop boss (1b " ') is inclined-plane, and this inclined-plane is outer low and inner high, and the gradient on inclined-plane is 15 °-30 °.
As preferably, the aperture of the non-insertion portion of described lower valve body (1b) is equal with the aperture of upper valve body (1a).
Beneficial effect: the utility model can relatively rotate lower valve body and upper valve body, thus allow the path section of lower valve hole be communicated with from different metering hole, so just can change and control flow, thus make this Proportional valve have the function of adjust flux, and then overcome conventional construction because can not regulable control flow and need the defect of plurality of specifications Proportional valve for subsequent use, and can not axial displacement be there is when relatively rotating in two valve bodies, so just can ensure sealing well, thus very effectively avoid the path section of lower valve hole to be communicated with two metering holes (1b ') simultaneously, so just can ensure normal work of the present utility model.
