Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings, but not as to restriction of the present utility model:
A kind of normally-open normally-close two-way proportional control valve, including valve seat 3, it is characterised in that: being symmetrically arranged with A valve 1, B valve 2 on described valve seat 3, A valve 1 includes electromagnetic valve component A102, it is provided with static iron core assembly A103 in electromagnetic valve component A102, in static iron core assembly A103, is provided with dynamic core assembly A101；B valve 2 includes electromagnetic valve component B202, is provided with static iron core assembly B203 in electromagnetic valve component B202, is provided with dynamic core assembly B201 in static iron core assembly B203；The duct being arranged symmetrically with it is provided with in valve seat 3, it is provided with reversing valve core A105 in the duct of the valve seat 3 corresponding with A valve 1, it is provided with reversing valve core B205 in valve seat 3 duct corresponding with B valve 2, A valve oil mouth 104 it is provided with on the duct of the valve seat 3 corresponding with A valve 1, it is provided with B valve oil mouth 204 on valve seat 3 duct corresponding with B valve 2, the middle part of valve seat 3 is provided with pressure oil import 301, and A valve oil mouth 104 is positioned at the left upper portion of valve seat 3, and B valve oil mouth 204 is positioned at the lower right side of valve seat 3；Line along A valve oil mouth 104, B valve oil mouth 204, pressure oil import 301, A valve oil mouth 104 constitutes isosceles triangle；Described pressure oil import 301 is provided with duct with A valve oil mouth 104 and communicates；Described pressure oil import 301 is provided with duct with B valve oil mouth 204 and communicates；The lower section being provided above drain tap A106, B valve oil mouth 204 of described A valve oil mouth 104 is provided with drain tap B206.
When being embodied as, as in figure 2 it is shown, open mode of the present utility model: A valve 1 electric, automatically controlled ECU instruct electric after, A valve oil mouth 104 pressure, close drain tap A106, pressure rises, and the characteristic working curve figure of A valve 1 electric current and air pressure is as shown in Figure 5；B valve 2 obtains electric, after automatically controlled ECU instruction, to be pressed under reversing valve core B205 by electromagnetic force, carry out the work changing pressure, size of current adjust the delivery outlet pressure changing B valve oil mouth 204, the characteristic working curve figure of B valve 2 electric current and air pressure as shown in Figure 6, when completely closing pressure oil import 301, B valve oil mouth 204 communicates with drain tap B206, reaches the purpose of the complete pressure release of B valve oil mouth 204；A valve oil mouth 104 communicates with pressure oil import 301.
