Embodiment Construction
[0028] Below in conjunction with accompanying drawing and specific implementation method, the present invention will be described in further detail:
[0029] Such as figure 1 As shown, the present invention proposes a two-position three-way high-temperature reversing valve directly driven by a double voice coil motor, which is characterized in that it includes a valve body 1, a valve core 2, a sleeve 3, a baffle 4, a heat shield 5, Motor housing 6, flexible sealing ring 12, flexible sealing ring 13, lock nut 16, left and right voice coil motors; the voice coil motors include voice coil motor stator 7 and voice coil motor mover 8;
[0030] Both ends of the spool 2 press the flexible graphite sealing ring 13 tightly through the baffle plate 4 to form a dynamic seal. The locking nut 16 can adjust the compression degree of the flexible graphite sealing ring 13 through threads; the end of the spool 2 and the voice coil motor mover 8 are connected by threads and locked by nuts; the...

A two-position three-way high-temperature reversing valve directly driven by a double voice coil motor, including a valve body, a valve core, a sleeve, a baffle, a heat shield, a motor cover, a flexible sealing ring, a lock nut, left and right tone coil motor; the voice coil motor includes a voice coil motor stator and a voice coil motor mover; the two ends of the valve core press the flexible graphite sealing ring through the baffle to form a dynamic seal, and the lock nut can be adjusted by threads degree of compression; the end of the spool and the voice coil motor mover are connected by threads and locked by nuts; a heat shield is set between the voice coil motor and the valve body; the stator of the voice coil motor is connected to the motor cover by screws, and the motor cover , the heat shield, and the valve body are fixed by bolts and nuts, the sleeve compresses the flexible sealing ring, and the sleeve and the valve body are connected by screws. When the voice coil motor on one side generates thrust, the voice coil motor on the other side generates pulling force. Each voice coil motor independently controls a spool. The double spool is a ball-to-top structure. Movement under the action to control the on-off of the two outlet gases.
Description
technical field [0001] The invention relates to a two-position three-way reversing valve used in a high-temperature environment, which is used in the field of direct force control. Background technique [0002] At present, in the field of direct force control, there is no mature application of gas direct force in China, and for anti-tank missiles, there is no mature product at present because it requires gas direct force products with small space, light weight and high thrust. Two-way three-way high-temperature directional valve is a key component in the field of direct force control. At present, there is no mature product application in China. The existing high-temperature directional valve cannot achieve the field of direct force control with small size, light weight, fast response and large thrust. High temperature reversing valve requirements. Contents of the invention [0003] The technical problem solved by the present invention is: to overcome the deficiencies of t...
