The middle section of the inner cavity of the valve body 1 is provided with a valve core 2, and the valve core 2 is connected with a rotary switch 3. By rotating the switch 3, the valve element 2 can be controlled to be opened and closed. The inlet and outlet ends of the inner cavity of the valve body 1 are provided with stepped grooves 4, and limiting pieces 5 are arranged in the stepped grooves 4. The inner ring of the limiting piece 5 is provided with a magnetic clamping strip 6, and the fixing and the moving of the limiting piece 5 are realized through the interaction of the magnetic clamping strip 6 and the moving opening and closing piece 8. The outer ring of the end part of the moving opening and closing piece 8 is outwards extended with a screw rod lug 9, and the screw rod lug 9 is connected with one end of a pushing screw rod 10. The other end of the pushing screw rod 10 is connected with a conducting gear 11 arranged in a planetary gear slot 14. The transmission gear 11 rotates to drive the pushing screw rod 10 to move, so that the movement of the moving opening and closing piece 8 is realized. The rotary sleeve 18 is provided with planetary tooth grooves 14 formed by an inner plate 13 and an outer plate 12, and the planetary tooth grooves 14 are used for fixing the conductive gear 11 and are matched with the conductive gear to rotate.

The valve core 2 is controlled to be opened and closed by the rotary switch 3, so that the on-off and flow control of the pipeline are realized. The design of the stepped groove 4 and the limiting piece 5 improves the sealing performance of the valve and effectively prevents medium leakage. The magnetic clamping strips 6 in the limiting piece 5 interact with the moving opening and closing piece 8, so that the fixing and moving of the limiting piece 5 are more convenient and quicker. The motion opening and closing piece 8 is matched with the pushing screw rod 10 and the transmission gear 11, so that the valve action is more accurate and stable. The design of the planetary gear grooves 14 on the rotary sleeve 18 improves the fixability and rotational stability of the conductive gear 11. The stainless steel ensures high corrosion resistance and long service life of the valve.

The rotary sleeve 18 is sleeved on the outer ring of the inlet and outlet ends of the valve body 1 and is clamped by a limiting plate.

In the stainless steel plug-in high-tightness quick-plug pipe valve, a rotary sleeve 18 is sleeved on the outer ring of the inlet end and the outlet end of a valve body 1 and is clamped by a limiting plate. This design further enhances the sealing performance and stability of the valve. When the rotary sleeve 18 is sleeved on the outer ring of the inlet end and the outlet end of the valve body 1, a tight fit is formed between the rotary sleeve 18 and the valve body 1, and leakage of medium from a gap between the rotary sleeve 18 and the valve body 1 can be effectively prevented. In addition, the design of the rotary sleeve 18 can also play a certain role in protecting the valve core 2, and direct scouring and corrosion of external impurities or fluid to the valve core 2 are avoided. The position of the rotary sleeve 18 can be further fixed by clamping the limiting plate, so that the tight fit between the rotary sleeve and the valve body 1 is ensured. The design of the limiting plate can effectively prevent the rotary sleeve 18 from loosening or shifting in the operation process, so that the high sealing performance and stability of the valve are ensured. The combination of the swivel 18 and the limiting plate improves the sealing performance and stability of the valve, and ensures the reliability and safety of the pipeline system.

The planetary gear slot 14 is provided with a gear limiting end cover 15, the gear limiting end cover 15 is provided with a screw rod through hole 16, and a tightening spring 17 is arranged between the bottom of the planetary gear slot 14 and the conductive gear 11.

The gear limiting end cover 15 arranged on the planetary tooth groove 14 is mainly used for limiting the position of the transmission gear 11, ensuring the stable rotation of the transmission gear 11 in the planetary tooth groove 14 and preventing the transmission gear from shifting or falling off. A screw through hole 16 is provided on the gear limiting end cap 15 so that the pushing screw 10 can pass through the through hole to be connected with the transmission gear 11. The design ensures smooth transmission between the screw rod and the transmission gear 11, and avoids friction and abrasion between the screw rod and the end cover. A tightening spring 17 is arranged between the bottom of the planetary gear slot 14 and the transmission gear 11. The function of the jack spring 17 is to provide a certain elastic force, so that the conductive gear 11 always keeps a certain contact pressure with the bottom of the planetary gear slot 14. Therefore, vibration and noise in the transmission process can be reduced to a certain extent, and the stability and accuracy of transmission are improved.

The outer ring of the rotary sleeve 18 is provided with a magnetic clamping strip 6. The rotating sleeve 18 is made of a non-magnetic material. The number of the transmission gears 11 is at least three.

The magnetic clamping strips 6 arranged on the outer ring of the rotary sleeve 18 are used for interacting with the magnetic clamping strips 6 in the valve body 1 to fix and unlock the rotary sleeve 18. This design of the magnetic clamping strip 6 simplifies the operation process and facilitates the installation and removal of the swivel sleeve 18. To ensure that the function of the magnetic card strip 6 is not affected, the swivel sleeve 18 is made of a non-magnetic material. The choice of non-magnetic material avoids magnetic interference and ensures a stable fit between the swivel sleeve 18 and the valve body 1. At least three transfer gears 11 are designed to increase the stability and reliability of the valve drive. The matched use of the plurality of conductive gears 11 disperses the stress and reduces the load born by a single gear, thereby prolonging the service life of the gear.

The working principle is that when an external air pipe is needed, the planetary tooth groove 14 drives the gear to rotate by rotating the rotary sleeve 18, so that the screw rod transversely moves to drive the moving opening and closing piece 8 to transversely move, the tail end of the screw rod pushes the elastic clamping plate 7 open, then the air pipe is inserted into the air pipe, the end of the air pipe is pushed to the bottom of the stepped groove 4, at the moment, the rotary sleeve 18 is reversely rotated, so that the moving opening and closing piece 8 returns to the original position again, the elastic clamping plate 7 can clamp the air pipe due to the barb shape of the elastic clamping plate 7, the quick insertion of the air pipe is completed, and when the air pipe is needed to be pulled out, the rotary sleeve 18 is controlled again to drive the moving opening and closing piece 8, so that the elastic clamping plate 7 is pushed open, and the external air pipe can be pulled out.
