Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
With reference to Fig. 1-3, a kind of check-valves of regulating flow quantity, including valve body 1, the both ends of valve body 1 are equipped with flange ring 3,
The upper end of valve body 1 is equipped with body 2, and valve body 1 and the junction of body 2 are equipped with baffle 12, and the top of body 2 is equipped with scale 14, machine
Worm screw 7 is equipped with body 2, the side of worm screw 7 is equipped with the first worm gear 6, and worm screw 7 engages with the first worm gear 6, the opposite side of worm screw 7
Equipped with the second worm gear 13, and worm screw 7 engages with the second worm gear 13, fixed at the wheel bore of the first worm gear 6 and the second worm gear 13 to connect
Shaft 5 is connected to, the one end of each shaft 5 away from the first worm gear 6 and the second worm gear 13 through body 2 and is fixedly connected with turntable
4, body 2 is run through on the top of worm screw 7, is equipped with cavity 8 in valve body 1, is equipped with current limiting plate 9 vertically in cavity 8, the bottom of worm screw 7 is passed through
