[0039] The operation method of this utility model is as follows:

[0040] During the distillation process of winemaking, this utility model is installed on the overflow pressure relief pipe of the earthen pot, and the air outlet pipe 12 is connected to the overflow pressure relief pipe, and the air inlet pipe 13 is connected to the air. Under normal circumstances, the steel ball 4 falls and seals the air inlet 2 due to gravity or the positive pressure of the earthen pot, ensuring that the earthen pot can be used under positive pressure and ensuring the winemaking distillation operation. When the earthen pot drains water as needed, a closed cavity space is generated inside the earthen pot. When the steam is turned off or cold water is introduced into the earthen pot, the temperature of the cavity space decreases, thereby generating negative pressure, which attracts the still and other production equipment together. When the closed cavity space of the earthen pot generates negative pressure, the negative pressure will pull the steel ball 4 away from the air inlet 2, or even directly touch the steel ball stop bar 5. At this time, the outside air will enter the earthen pot through the air inlet pipe 13, the air inlet 2, the cavity 3, the air outlet pipe 12 and the air outlet 1, so that the closed cavity space of the earthen pot is balanced with the outside atmosphere, preventing the earthen pot from being damaged due to negative pressure.

[0041] When draining water from the boiler, if Figure 4 As shown, pulling the external pull rod 9 causes the screw rod 11 to rotate under the action of the rotating joint 10 and the support rod, and further drives the ejector pin 7 to rotate 90° to lift the steel ball 4. At this time, this utility model can be used as an ordinary valve to release water, which can reduce the risk of burns to the operator from the water or steam in the boiler.

[0042] When used in a multi-shift parallel wine conveying pipeline for transferring tail wine, the vent pipe 12 is connected to the first branch pipe of the wine conveying pipeline, and the inlet pipe 13 is connected to the external container for wine storage. The entire one-way valve is set vertically. The pump is used to pump out the wine. The wine lifts the steel ball through the inlet pipe 13 and the inlet 2, or the external pull rod 9 is manually pulled in advance to rotate the pin 7 and lift the steel ball 4. Further, the wine reaches the first branch pipe through the inlet 2, the cavity 3 and the vent pipe 12 and flows to the main pipe. The second branch pipe, which is set in parallel with the first branch pipe, has a downward pressure on the steel ball 4 because the wine enters from the vent pipe 12, making the steel ball 4 fit more closely to the inlet 2, ensuring its airtightness and preventing liquid leakage from adjacent shifts.

[0043] Although the embodiments of the utility model are described in the specification, these embodiments are only as a prompt, should not limit the protection scope of the utility model. In the range without departing from the utility model purposes, various omissions, replacements and changes should be contained in the protection scope of the utility model.
