Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment:
Fig. 1 to Fig. 5 is please referred to, the present invention provides a kind of technical solution:
A kind of Dual sealed valve, including valve body 1, turning handle 2, Bidirectional-screw 3, worm gear 4, worm screw 5, sealing plate 6, connection frame
7, sleeve 8 and sealing ring 9, in which:
One end of valve body 1 is water inlet, the other end is water outlet, and wherein the water inlet of valve body 1 is respectively equipped with water outlet
Two rectangular openings 11, turning handle 2 are rotatably installed on valve body 1 by bearing and are through to the inside of valve body 1, wherein turning handle 2 and valve
1 contact portion of body is sealing installation, and the both ends of Bidirectional-screw 3 pass through bearing respectively and are mounted in valve body 1, wherein Bidirectional-screw 3
For the thread rotary orientation at both ends on the contrary, worm gear 4 is solidly set on the middle of Bidirectional-screw 3, one end of worm screw 5 is mounted on valve body by bearing
1 is interior, the other end is fixedly connected with the turning handle 2 being through to inside valve body 1 by shaft joint, and worm gear 4 and worm screw 5 cooperate
