[0014] The specific implementing method of the utility model is further explained in detail in combination with the drawings.

[0015] By Figures 1 to 3 The utility model discloses a disc-shaped shell 1, the upper side wall of shell 1 has water inlet cylinder 2, the side wall of shell 1 is fixed with multiple water outlet cylinders 3, one end of water outlet cylinder 3 is placed in the cavity of shell 1, and the cavity of shell 1 has multiple small balls 4 that are evenly distributed in a circle, and multiple small balls 4 correspond to multiple water outlet cylinders 3 one by one;The cavity of shell 1 has horizontal and active rotating gear 5, the outer circular surface of small ball 4 is provided with arc rack 6, rack 6 is engaged with gear 5, and the inner side of shell 1 is provided with tooth structure engaged with rack 6;Gear 5 rotates and drives multiple small balls 4 to roll along the inner wall of shell 1 through multiple racks 6, and when small ball 4 reaches the corresponding water outlet cylinder 3, small ball 4 can block water outlet cylinder 3.

[0016] In order to ensure that rack 6 and gear 5 are engaged, the upper side wall of shell 1 is in contact with the upper side wall of rack 6, the lower side wall of shell 1 is in contact with the lower side wall of rack 6, and the upper side wall and the lower side wall of shell 1 can clamp rack 6 to ensure that rack 6 and gear 5 remain in engagement.

[0017] To facilitate the smooth flow of cooling water, there is a gap between the rack 6 and the upper side plate of the housing.

[0018] The gear 5 is connected to a motor 7, which is fixed to the outer side of the lower side wall of the housing 1.

[0019] The cross-section of the outer shell 1 is dumbbell-shaped.

[0020] It is worth noting that the length of the rack 6 is less than the circumference of the ball 4. The structure of the rack 6 and the ball 4 is similar to that of an incomplete gear 5. The upper and lower side plates of the outer shell 1 limit the rack 6, ensuring that the rack 6 and the gear 5 can mesh. When the ball 4 reaches the water outlet cylinder 3, the ball 4 can just block the water outlet cylinder 3. The motor 7 is controlled by the PLC unit, and the temperature conduction is carried out by the temperature sensor.

[0021] When using, such as Figures 1-3 As shown, when the reactor temperature is too high and the valve is opened, cooling water enters the outer shell cavity 1 through the upper inlet. The cooling water fills the entire outer shell cavity 1 through the gap between gear 5 and large gear 5, and then enters the cooling pipes on the reactor through multiple outlet pipes 3 to cool the reactor. After a period of time, when the reactor temperature is suitable, the valve needs to be closed. Specifically, motor 7 drives gear 5 to rotate, and gear 5 drives multiple small balls 4 to rotate simultaneously via rack 6. Figure 3 As shown, when ball 4 reaches the outlet of cylinder 3 and forms a blockage, the entire valve closes and cooling water cannot flow.

[0022] In this design, the ball 4 is driven by the gear 5. The structure formed by the ball 4, the gear 5, and the outer shell 1 is similar to that of the planetary gear 5. The ball 4 acts as a sealing element. During the process of sealing or opening the water outlet cylinder 3, the ball 4 rolls instead of sliding, which greatly reduces friction loss and can effectively extend the overall life of the valve.

[0023] This utility model has a clever structure. Compared with the sealing components of traditional valves, it uses rolling instead of sliding, which can greatly reduce the frictional loss of the sealing components, greatly extend the overall service life of the valve, improve the heat preservation effect of the reactor, and facilitate safe production.
