[0027] Embodiment 2:

[0028] On the basis of the first embodiment, in order to realize the convenience of connecting the upper valve and the lower valve, an upper valve 3 is provided on the upper surface of the lower valve 1, a connecting groove 15 is provided on the surface of the upper valve 3, and an electromagnetic 4 is fixed on the surface of the upper valve 3, and the electromagnetic 4 can control the opening and closing of the lower valve 1;

[0029] There are multiple groups of connecting grooves 15, which are symmetrically distributed on the upper surface of the upper valve 3. There are multiple groups of clamping plates 2, which are symmetrically distributed on the arc surface of the rotating shaft 16. The clamping plates 2 correspond to the connecting grooves 15. The clamping plates 2 are clamped in the connecting grooves 15. Under the restriction of the multiple groups of clamping plates 2, the connection between the upper valve 3 and the lower valve 1 is realized, and the two are movably connected.

[0030] The arc surface of the push rod 8 is sleeved with a spring 9. Due to the elasticity of the spring 9, the spring 9 resets and pushes the limit plate 6 to move. The inner wall side surface of the groove 7 is provided with a sliding groove 12 to position the movement of the slider 19. The slider 19 is fixed to the side surface of the limit plate 6.

[0031] There are multiple groups of slide grooves 12, which are symmetrically distributed on the inner wall side surface of the groove 7. There are multiple groups of sliders 19, which are symmetrically distributed on the side surface of the limit plate 6. The sliders 19 correspond to the slide grooves 12. The sliders 19 are clamped in the slide grooves 12 to position the sliders 19. The two are movably connected.

[0032] The size of the notch 13 is the same as that of the push rod 8, the size of the storage groove 14 is the same as that of the baffle 18, the size of the baffle 18 is larger than that of the push rod 8, the baffle 18 corresponds to the storage groove 14, the baffle 18 is stuck in the storage groove 14, and the notch 13 prevents the push rod 8 from escaping from the storage groove 14.

[0033] The specific scheme is as follows: the lower valve 1 is installed in the pipeline, and then the upper valve 3 is placed on the upper surface of the lower valve 1 and aligning it sideways, and the gear 5 is rotated. The rotation of the gear 5 will drive the rotating shaft 16 to rotate, and the rotation of the rotating shaft 16 will drive the clamping plate 2 to rotate. When the clamping plate 2 is completely stuck in the connecting groove 15, the rotation of the gear 5 is stopped. At this time, under the restriction of multiple groups of clamping plates 2, the connection between the upper valve 3 and the lower valve 1 is achieved. At the same time, due to the elasticity of the spring 9, the reset of the spring 9 will push the limit plate 6 to move, so that the limit block 17 is stuck in the tooth groove of the gear 5, so that the gear 5 cannot rotate. The inability of the gear 5 to rotate will cause the clamping plate 2 to be unable to separate from the connecting groove 15, thereby achieving the stability of the connection between the upper valve 4 and the lower valve 1. This structure is simple and easy to operate. No tools are required when separating or connecting the upper valve 3 and the lower valve 1, which is conducive to improving its use effect.
