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) and a connecting sleeve (3) successively, wherein connecting sleeve (3) is threaded with this large footpath section; Be embedded with a seal ring (4) 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;
Described lower valve body (1b) top is inserted in the large footpath section of upper valve body (1a) through hole bottom, this insertion part is threaded with this large footpath section, and lower valve body (1b) upper-end surface and described seal ring (4) bottom surface are close to, and the path section of lower valve body (1b) through hole can be communicated with wherein metering hole described in any one (1b ') simultaneously.
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.
As optimizing design scheme, the number of described metering hole (1b ') is 4, and its number is moderate.
As preferably, the aperture of the non-insertion part of described lower valve body (1b) is equal with the aperture of upper valve body (1a).
For the ease of connecting external connector, the special blind hole (1b ") that is connected with external connector by the center hole of described connecting sleeve (3) all makes interior threaded hole.
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 the utility model just solves large problem by little change, there is good practicability.
