Triple valve work during, coil receive electric impulse signal, driving rotor assembly 2 rotate, while drive with
The screw arbor assembly 4 that rotor assembly 2 is fixedly connected rotates；Nut assembly 3 and screw arbor assembly 4 cooperate, and the rotation of screw arbor assembly 4 is transported
Turn becomes being axially moved, and valve head assembly 5 is driven to be axially moved.
The conical surface of first valve head 11 and the first valve port 9 cooperate, and the conical surface of the second valve head 12 and the second valve port 10 cooperate, valve head
When component 5 is in the middle position of the first valve port 9 and the second valve port 10, the first valve port 9 and the equal standard-sized sheet of the second valve port 10；Work as valve head
When component 5 moves axially upwards, 9 aperture of the first valve port is gradually reduced, until completely closing, the second valve port 10 is protected in the process
Hold standard-sized sheet；When valve head assembly 5 is moved axially downwards by middle position, 10 aperture of the second valve port is gradually reduced, until closing completely
It closes, the first valve port 9 keeps standard-sized sheet in the process.Coil component passes through control forward and reverse the first valve of motor adjustment of rotor assembly 2
The aperture of the 9, second valve port 10 of mouth achievees the purpose that control assignment of traffic.
These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
