Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

The following embodiments are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0031] The utility model discloses a biological airtight valve, including: Figure 1 The utility model discloses a biological airtight valve, including:

[0032] The housing 101 is provided with a first opening at the bottom and a second opening at the side. A first control shaft 213 is arranged in the housing 101, and the bottom end of the first control shaft 213 extends out of the first opening. The bottom end of the first control shaft 213 is connected to the valve core of the valve, and the bottom end of the first control shaft 213 forms a connecting end 214. The cross section of the connecting end 214 is rectangular, and the connecting end 214 is inserted into the valve core to connect the biological airtight valve and the valve core of the valve.

[0033] The manual control assembly is arranged in the housing 101 and provided with a manual control end 105 corresponding to the second opening. The manual control assembly is drivingly connected to the first control shaft 213.

[0034] The electric drive assembly is arranged in the housing 101 and drivingly connected to the manual control assembly.

[0035] The hand control assembly controls the rotation of the first control shaft 213, so that the first control shaft 213 can control the valve opening degree of the valve. When the electric drive assembly loses the control effect due to the influence of the environment, the rotation of the first control shaft 213 is controlled by the hand control assembly to control the valve opening degree of the valve.

[0036] In a preferred embodiment of the biological airtight valve, as shown in Figure 3 and Figure 4 The first control shaft 213 includes a shaft rod and a control gear 207 arranged on the side of the shaft rod, and the control gear 207 is in the shape of a sector. The hand control assembly includes a hand control lead screw 212 engaged with the control gear 207, and the end of the hand control lead screw 212 forms a hand control end 105, which is a rectangular or polygonal connecting groove. By inserting a corresponding four-angle wrench or hexagonal wrench into the connecting groove, the rotation of the hand control lead screw 212 can be manually controlled.

[0037] Preferably, the housing 101 is provided with a hand control plate 206 corresponding to the position of the hand control end 105, which is used to strengthen the strength of the corresponding position of the housing 101.

[0038] Further, as shown in Figure 3 and Figure 4 The electric drive assembly includes a motor 201, a gear transmission set and a fifth gear 205. The motor 201 is arranged in the housing 101, and the motor 201 has a rotatable motor 201 shaft. The first gear is connected to the motor 201 shaft and engaged with the gear transmission set. The fifth gear 205 is connected to the hand control lead screw 212 and engaged with the gear transmission set. Through the rotation of the motor 201 shaft, the first gear rotates to drive the gear transmission set to transmit power. The design of the gear transmission set ensures the stable transmission of power and reduces energy loss. When the gear transmission set is driven by the first gear, the fifth gear 205 also rotates to drive the hand control lead screw 212 to rotate. This design enables the electric drive assembly to effectively control the rotation of the hand control assembly, thereby achieving precise adjustment of the valve opening degree of the valve. In addition, the use of the gear transmission set also enhances the stability and durability of the entire device, so that the biological airtight valve can maintain excellent performance in various environments.

Such a cascading gear transmission design not only ensures the continuous transmission of power, but also increases the torque through multi-stage speed reduction, so that the hand control assembly is more labor-saving when adjusting the valve opening. The entire gear transmission set is designed precisely, the engagement between the gears is tight and gapless, effectively reducing energy loss during transmission and improving the working efficiency of the biological containment valve.

[0040] Preferably, the shaft rod near the top is provided with an indicating gear, and the top end of the shaft rod is provided with an indicating plate 210, which is marked with OPEN, CLOSE and turning indications.

[0041] Preferably, as shown in Figure 1 , Figure 2 and Figure 5 , the shell 101 forms a first cavity 107 corresponding to the position of the motor 201, a second cavity 108 corresponding to the position of the gear transmission set, and a third cavity 111 corresponding to the position of the first control shaft 213 and the hand control assembly. The first cavity 107 and the second cavity 108 are communicated, a communication port 109 is arranged between the third cavity 111 and the second cavity 108, the outer wall of the second cavity 108 is connected with the first cover plate 104, the top of the third cavity 111 is connected with the second cover plate 102, and the second cover plate 102 is provided with an observation window 103 made of transparent material, which is convenient for the staff to watch the indicating plate 210.

The first sensor 211 is used to detect the rotation state of the first control shaft 213. When the first control shaft 213 rotates, the indicating gear rotates, thereby driving the sixth gear 209 to rotate. The first sensor 211 accurately captures the rotation state of the sixth gear 209, and converts the rotation information into an electrical signal through the internal sensing element. This electrical signal is then transmitted to the motor 201. The motor 201 determines the opening or closing state of the biological containment valve and the direction and speed of rotation according to the received signal. Such a design not only improves the automation degree of the biological containment valve, but also ensures the real-time monitoring of its working state, which provides great convenience for subsequent maintenance and troubleshooting.

The third sensors also convert the position information into electrical signals through internal sensing elements and transmit the signals to the motor 201. After the control system in the motor 201 receives the signals, the current state of the biological containment valve can be determined in real time, such as whether it is fully open, fully closed or at an intermediate position. Such a design further enhances the intelligent degree of the biological containment valve, enabling the operator to more accurately understand and control the running state of the valve.

[0046] Preferably, by arranging the first mounting plate 208 in the shell 101 and arranging the first control shaft 213 through the first mounting plate 208, not only the stable rotation of the first control shaft 213 is ensured, but also the sixth gear 209 and the control gear 207 can be arranged on the upper and lower sides of the mounting plate respectively, thereby realizing effective isolation and precise control of gear transmission. Such a structural design not only improves the overall stability of the biological containment valve, but also reduces the wear between the components and prolongs the service life of the equipment.

[0047] Preferably, the fourth cavity 110 is formed in the shell 101 corresponding to the positions of the support frame and the first mounting plate 208, and the second cover plate 102 is arranged on the fourth cavity 110.
