[0026] See also Figure 1 The controllable regulating device of the liquor multi-pressure valve of this embodiment is arranged on the multi-pressure valve, including an actuator located on the multi-pressure valve, a pressure sensor 10 located inside the multi-pressure valve, and a controller located outside the multi-pressure valve for sending a control signal.

[0027] In the utility model, the pressure sensor 10 detects the pressure change in the liquor production process in real time and transmits the detection signal to the controller; the controller compares and processes the received detection signal and the preset pressure control parameters to generate a corresponding control signal; the actuator drives the multi-pressure valve to perform corresponding actions according to the control signal, thereby realizing accurate control of the pressure in the liquor production process.

[0028] See also Figure 1-2 In this embodiment, the multi-pressure valve includes a valve body 1 and a valve core located in the valve body 1, wherein the valve core includes a valve stem 6 slidably installed in the valve body 1 and a valve plug 7 fixedly connected to the lower end of the valve stem 6, and an inlet 3 is opened on one side of the valve body 1, and an outlet 4 is opened on the other side;

[0029] It should be noted that the inlet 3 and the outlet 4 are distributed up and down in the valve body 1, and the inlet 3 and the outlet 4 are connected by the inner cavity in the valve body 1, and the valve plug 7 is located in the connecting part of the inner cavity of the valve body 1, and a return spring 8 is installed between the valve plug 7 and the inner wall of the valve body 1 to push the valve plug 7 to move and return.

[0030] In a specific implementation, since the inner cavity of the valve body 1 from the inlet 3 to the outlet 4 extends toward the middle to form a partition and is blocked by the valve plug 7, it can be understood that the flow pressure of the multi-pressure valve is adjusted by increasing the distance between the valve plug 7 and the inner cavity wall of the valve body 1, that is, adjusting the flow area.

[0031] In addition, the inner cavity of the valve body 1 extends upward, and a reed 9 is fixedly mounted on the top of the valve body 1 . The pressure sensor 10 is fixedly mounted at a position where the reed 9 faces the valve stem 6 , and the valve stem 6 abuts against the pressure sensor 10 .

[0032] With this design, since the reed 9 itself has a certain elasticity, the pressure sensor 10 can be closely attached to the valve stem 6, and the change value of the liquid pressure on the reed 9 can also be directly transmitted to the pressure sensor 10 for sensing.

[0033] See also Figure 1 In this embodiment, a penetration plate 5 is fixedly mounted on the inner wall of the valve body 1 , and the valve stem 6 is slidably connected to the penetration plate 5 .

[0034] Since the penetration plate 5 is located in the valve body 1 , the up and down movement of the valve stem 6 can be guided and pulled, thereby improving the movement stability of the valve stem 6 .

[0035] In this embodiment, the actuator includes an outer shell 2 fixedly connected to the valve body 1, a pressure structure built into the outer shell 2, and an electric motor 18 connected to the pressure structure as a power element, wherein the electric motor 18 is controlled by a controller signal, and a bracket 17 fixedly connected to the outer shell 2 is fixedly installed on the outside of the electric motor 18;

[0036] The pressure-applying structure includes a nut 13 fixedly mounted on the outer shell 2 , an actuator rod 14 threadedly connected to the nut 13 , and a pressure-adjusting spring 12 located at the bottom of the actuator rod 14 .

[0037] In a specific implementation, the controller sends an execution signal to the motor 18 , and the motor 18 drives the power end to pull the execution rod 14 to move, thereby changing the pressure value of the pressure regulating spring 12 .

[0038] Specifically, the top end of the actuator rod 14 is fixedly connected with a connecting pin 20, and the power end of the motor 18 is fixedly installed with a shaft sleeve 19, and the shaft sleeve 19 is slidably connected to the connecting pin 20;

[0039] Preferably, a hole is opened at one end of the shaft sleeve 19, and the openings of the connecting pin 20 and the shaft sleeve 19 correspond to each other and are both hexagonal.

[0040] In this design, by the mutual insertion of the connecting pin 20 and the sleeve 19, the sleeve 19 can pull the connecting pin 20 to rotate when rotating, and at the same time, the connecting pin 20 can slide relative to the sleeve 19, so that the actuator rod 14 can extend toward the outer shell 2 when rotating.

[0041] See also Figure 1 In order to improve the contact stability of the actuator rod 14 relative to the pressure-adjusting spring 12, a turntable 15 is fixedly installed on one end of the actuator rod 14 extending into the outer shell 2, and a tray 16 is rotatably installed outside the turntable 15. A mounting frame 11 located in the outer shell 2 is also fixedly installed on the top of the reed leaf 9. One end of the pressure-adjusting spring 12 is fixedly connected to the tray 16, and the other end is fixedly connected to the mounting frame 11, so that the pressure-adjusting spring 12 can be stably built into the outer shell 2.

[0042] The working principle of the above embodiment is:

[0043] During the liquor production process, the pressure changes during the process of flowing through the inlet 3 to the outlet 4. For example, when the pressure value increases, the reed 9 located at the top of the valve body 1 is pushed upward by the pressure. At this time, the reed 9 drives the pressure sensor 10 to lift up, and the return spring 8 located at the lower end of the valve plug 7 pushes the valve plug 7 to lift up, so that the valve stem 6 at the upper end of the valve plug 7 continuously abuts against the pressure sensor 10. During this process, the return spring 8 pushes the valve plug 7 to lift up, so that the elastic potential energy stored in the return spring 8 is reduced, so that the pressure difference received by the pressure sensor 10 can be changed, and the pressure sensor 10 transmits the detection signal to the controller. The controller compares and processes the received detection signal and the preset pressure control parameters to generate a corresponding control signal; the actuator drives the motor 18 according to the control signal, and the motor 18 drives the sleeve 19 and the connecting pin 20 connected to the output end to pull the actuator rod 14 to move. The actuator rod 14 is threadedly engaged with the nut 13 through a rotation action, and the turntable 15 at the end of the actuator rod 14 pushes the tray 16. When the tray 16 is close to the mounting frame 11, it can squeeze the pressure regulating spring 12, thereby increasing the spring force of the pressure regulating spring 12 to force the upper and lower pressure difference values ​​of the spring leaf 9 to maintain a balance, that is, to achieve a quick response.
