Body, 2a are groove spool, and 2b is pectination slot spool, and 5a is dual flow path pedestal.
Specific embodiment
Present invention design fluid control valve structure type is as shown in Figure 1.Fluid control valve composition parts are main
Including：Valve body (1)；Spool (2)；Cover board (3)；Rocking arm (4)；Pedestal (5)；Attachment screw (6).Wherein valve body (1), cover board (3),
Pedestal (5) is fixed structure, and spool (2) and rocking arm (4) are turntable.
The fluid control valve that the present invention designs, valve body (1) is equipped with grid-like runner, as shown in Figure 2.Spool (2)
Outer surface base shape is cylindrical surface, and grid-like runner also is provided in spool (2), as shown in figure 3, runner passes through spool (2)
Cylindrical surface, runner one end be equipped with guiding angle, reduce flow losses.
Control valve for fluids designed by the present invention, rocking arm (4) and spool (2) link together, and pass through outer power drive rocking arm
(4) band movable valve plug (2) rotates, and realizes break-make control and the traffic organising of flow path.As shown in figure 4, under the effect of outer power drive, shake
Arm (4) can -45 °~+45 ° of deflection angle, making the spool to link together (2), the rotation of spool sends out runner around axial-rotation
Changing makes flow path close or connect.
The fluid control valve that the present invention designs, the external cylindrical surface of spool (2) can design partial groove, modified
Groove spool (2a) and the contact area of valve body (1), cover board (3) reduce, and can reduce the risk of abrasion and clamping stagnation.
Fluid control valve designed by the present invention can adjust stream according to required flow or the demand of circulation area
Height, the length equidimension in road, valve body (1) and spool (2) runner are cell structure in fluid control valve of the invention, are led to
It crosses grid and booster action is risen to runner, pass through the length to valve body (1) and spool (2) and quantity, height, width of grid etc.
Size is adjusted, and can realize different circulation areas, meets different valve flow requirements.
Fluid control valve designed by the present invention can modify to the structure of valve body (1) and pedestal (5), respectively
Increase a channel, obtain dual flow path valve body (1a) and dual flow path pedestal (5a).As shown in Figure 5 and Figure 6, in spool (2), groove
After spool (2a) combines respectively with dual flow path valve body (1a) and dual flow path pedestal (5a), can realize fluid break-make control and
The traffic organising of both direction.As shown in fig. 7, after the angle change of rocking arm (4) driving groove spool (2a), runner occurs therewith
Variation closes flow path or fluid is made to be flowed out along different flow paths.
Fluid control valve designed by the present invention is also designed to the continuous groove of pectination on the cylindrical surface of spool (2),
As shown in figure 8, at this point, the exradius of pectination slot spool (2b) is smaller 0.1~1mm than the diameter of bore of valve body (1), cover board (3),
It is contactless between pectination slot spool (2b) and valve body (1), cover board (3), the sealing between them is real by pneumatic action
It is existing, after non-contact seals, the risk of control valve for fluids abrasion or clamping stagnation can be further reduced, while be suitable for fluid
Control the operating condition of valve member thermal deformation at high temperature.As shown in figure 9, pectination slot spool (2b) and dual flow path valve body (1a),
After dual flow path pedestal (5a) combination, the break-make control of fluid and the traffic organising of both direction can also be realized.
