It on door machine seat 300 and is oppositely arranged, valve engine base 300 provides the support to each functional component, and associated load is transmitted to
The utricule of near space dirigible.First valve system 100 is identical with the structure of the second valve system 200, with the first valve system
It is described in detail for 100.
First valve system 100 includes valve deck 1, driving mechanism 2, transmission mechanism 3 and link mechanism 4, and driving mechanism 2 is used
In output torque, it is fixed on the outside of valve engine base 300, driving mechanism 2 includes motor 21 and in mating connection with the motor
Gear-box 22, the motor 21 of driving mechanism 2 is fixedly connected by motor support base 23 with stent 5.
Transmission mechanism 3 includes differential leading screw 31, left-handed nut 32 and right-handed nut 33, and transmission mechanism 3 is pacified by stent 5
On valve engine base 300, valve deck 1 is connect by link mechanism 4 with transmission mechanism 3, and driving mechanism 2 can drive differential leading screw
31 rotations so as to which left-handed nut 32 and right-handed nut 33 be driven to be moved on differential leading screw 31, and then drive valve deck 1 to move,
Realize being turned on and off for valve deck 1.
The both ends of differential leading screw 31 are connect by bearing with stent 5, and one end of differential leading screw 31 passes through spline and gear-box
22 connections.Differential leading screw 31 is equipped with the left hand thread to match with left-handed nut 32 and the right side to match with right-handed nut 33
Revolve screw thread so that left-handed nut 32 and right-handed nut 33 can move on differential leading screw 31, so as to which valve deck 1 be driven to move.
The other end of differential leading screw 31 is equipped with rotation dependent element (not shown), for measuring the angle that differential leading screw 31 rotates,
And then pass through the Lift of software monitors valve deck 1.
