Description

Technical Field

[0001] The invention relates to the technical field of fresh-keeping devices, in particular to a wine valve. Background Art

[0002] Draft beer is famous for its "pure flavor, fresh and delicious" all over the world, but it must be stored in complex special equipment, which limits its popularity and prevents it from entering thousands of households. Although barreled beer also uses fresh beer, there is not enough pressure in the barrel to maintain the carbon dioxide content in the beer. During the process of loading, transporting and selling the beer, it oxidizes in contact with air, thus destroying the taste and flavor of the beer.

[0003] As the beer in the barrel is continuously taken out, the carbon dioxide content in the barrel will decrease accordingly, which will easily lead to oxidation and deterioration of the beer. For this reason, technicians have designed a beer dispenser with a carbon dioxide gas cylinder, through which the carbon dioxide in the carbon dioxide gas cylinder is filled into the barrel to increase the carbon dioxide content in the barrel, thereby achieving the purpose of preserving freshness. For example, a pressure-regulated carbon dioxide beer dispenser disclosed in a Chinese patent (publication number CN2199973) has the following problems in the installation of the existing wine valve: when the carbon dioxide gas cylinder is first connected to the valve body of the wine valve, the gas in the carbon dioxide gas cylinder will quickly run out of the carbon dioxide gas cylinder. The carbon dioxide cylinder has not yet been sealed and installed with the wine barrel, which leads to the loss of gas in the carbon dioxide cylinder. When the wine valve is sealed and connected to the wine barrel first, the inside of the wine barrel will be connected to the outside through the wine valve, that is, the outside air will run into the wine barrel through the wine valve, which will cause the beer in the wine barrel to deteriorate. Therefore, it is necessary to connect a stop valve to the wine valve. The stop valve is used to prevent the loss of gas in the carbon dioxide cylinder and prevent the outside air from running into the wine barrel through the wine valve. However, connecting a stop valve to the outside of the wine valve makes the overall size of the wine valve larger and the structure more complicated. Therefore, the existing wine valve needs to be improved. Summary of the invention

[0031] like Figure 4 , Figure 6 and Figure 7 As shown: the valve seat 1 is provided with a first accommodating chamber 12, the tube body 2 is provided with a first air guide 24 connecting the air guide port 223 and the first accommodating chamber 12, the valve seat 1 is provided with a second air guide 51 arranged in a direction parallel to the wine outlet chamber 111, the first accommodating chamber 12 is connected with the second air guide 51 through the first valve port 13, the lower end side wall of the valve seat 1 is provided with an air outlet 52 connecting with the second air guide 51, and the carbon dioxide gas in the carbon dioxide gas cylinder finally enters the wine barrel 7 through the air outlet 52. The first accommodating chamber 12 is provided with a push rod 121, a first plug 122 arranged on the push rod 121, and a first elastic member 123 arranged in the first accommodating chamber 12 for driving the push rod 121 to move downward so that the first plug 122 blocks the first valve port 13. The lower end of the valve seat 1 is rotatably provided with a wine plug 4, which is sleeved on the outer periphery of the pipe column 11. The upper end surface of the wine plug 4 is provided with an arc groove 41 centered on the central axis of the wine plug 4 at a position corresponding to the push rod 121, and the lower bottom surface of the arc groove 41 is The distance from the upper end surface of the wine stopper 4 gradually decreases along the extending direction of the arc groove 41. The lower end of the push rod 121 passes through the first valve opening 13 and is abutted against the lower bottom surface of the arc groove 41. The opening and closing of the first valve opening 13 is controlled by the relative rotation of the wine stopper 4 and the valve seat 1. Specifically, in the initial position, the push rod 121 is abutted against the lowest end of the arc groove 41 of the wine stopper 4. At this time, the first plug head 122 on the push rod 121 is in a state of blocking the first valve opening 13. When the wine stopper 4 is equivalent to the rotation of the valve seat 1 The position where the arc groove 41 of the first plug 122 contacts the push rod 121 is gradually rotated from the lowest end to the highest end. During this process, the push rod 121 is gradually pushed up under the action of the lower bottom surface of the arc groove 41, so that the first valve port 13 is gradually opened. When the wine plug 4 is rotated in the opposite direction, the push rod 121 is gradually moved downward under the action of the first elastic member 123, so that the first valve port 13 is gradually closed again. A limit structure is provided between the wine plug 4 and the valve seat 1 to limit the rotation stroke of the wine plug 4 and the valve seat 1.

[0032] The wine valve of the present invention does not require an external stop valve. The opening and closing of the first air duct 24 and the second air duct 51 can be controlled by relative rotation of the wine plug 4 and the valve seat 1, so that gas leakage can be effectively avoided when the wine valve is connected to the wine barrel 7 and the carbon dioxide cylinder 6.

[0033] In some embodiments: Figure 6 , Figure 8 and Fig. 9 The limiting structure includes a limiting block 15 arranged on the valve seat 1, and the wine plug 4 is provided with an arc-shaped avoidance groove 42. The limiting block 15 can rotate along the arc-shaped avoidance groove 42, and the rotation stroke of the wine plug 4 and the valve seat 1 is limited by the limiting cooperation between the limiting block 15 and the end face of the arc-shaped avoidance groove 42.

The wine stopper 4 is provided with a flat-cut groove 43 at a position corresponding to the deeper depth of the arc groove 41, and the flat-cut groove 43 is arranged on the wine stopper 4 in a centrally symmetrical manner. Through the above-mentioned arrangement, when the wine stopper 4 is assembled with the valve seat 1, there is no need to consider whether the wine stopper 4 is installed upside down, and it only needs to be aligned with the flat-cut groove 43 and inserted.

[0035] In some embodiments: Figure 7 The valve seat 1 is provided with a through hole penetrating the lower end surface of the valve seat 1 at the lower end corresponding to the first valve port 13, and a first annular cavity 14 is formed between the hole wall of the through hole and the outer periphery of the push rod 121. The valve seat 1 is provided with a sealing ring 54 sealingly matched with the push rod 121 at the bottom of the first annular cavity 14 corresponding to the first valve port 13, and the second air guide 51 is connected with the first accommodating cavity 12 through the first annular cavity 14.

[0036] In some embodiments: Figure 6-7 The valve seat 1 corresponds to a sleeve 5 fixedly mounted on the outer periphery of the pipe column 11, and a second air duct 51 is formed between the sleeve 5 and the pipe column 11. The air outlet 52 is arranged on the side wall of the sleeve 5 and is communicated with the second air duct 51. The sleeve 5 is provided with a step hole 53 for the push rod 121 to pass through. The step hole 53 is a structure with a larger upper part and a smaller lower part. The sealing ring 54 is sealingly installed at a position where the aperture of the step hole 53 is larger. Through this design, the problem of the difficulty in processing the second air duct 51 can be effectively solved. The second air duct 51 is formed by the sleeve-type design of the pipe column 11 and the sleeve 5, and it is also more convenient to design the sleeve 5 separately, thereby improving the processing efficiency of the second air duct 51.

The pressure relief rod 1621 and the second plug 1624 tend to move downward under the action of the second elastic member 1623, so that the second plug 1624 blocks the second valve port 161. By setting the structure of the overflow valve 162, the on-off of the second valve port 161 can be controlled manually and automatically. When the gas pressure in the first air guide channel 24 is greater than the set pressure, part of the gas can be discharged to the outside of the valve seat 1 through the overflow valve 162. Specifically, part of the gas passes through the second valve port 161 and then is discharged to the outside of the wine valve through the second accommodating chamber 16 and the second annular cavity 1625; when the push rod 121 is manually lifted, the second valve port 161 is opened so that part of the gas can be discharged to the outside of the valve seat 1 through the overflow valve 162.

By designing the pressure reducing valve structure 21, the depth of the plug 226 extending into the third accommodating chamber 22 can be adjusted as needed to adjust the set pressure value (the pressure value of the output carbon dioxide) of the pressure reducing valve structure 21, and the adjustment is relatively convenient.

[0044] When the gas cylinder installation port 2312 is not connected to the carbon dioxide gas cylinder 6, the piston 221 drives the push rod 121 to move toward the side of the compressed fourth elastic member 233 under the elastic force of the third elastic member 222, so that the fourth valve port 2311 is in an open state. After the gas cylinder installation port 2312 is connected to the carbon dioxide gas cylinder 6, the carbon dioxide gas pushes the piston 221 to move toward the side of the compressed third elastic member 222 through the fourth valve port 2311. After the forces on both sides of the piston 221 reach a balance, the pressure on the side of the piston 221 close to the fourth accommodating chamber 23 gradually increases and breaks the balance. , the ejector pin 232 blocks the fourth valve port 2311 under the elastic force of the first elastic member 123. At this time, the carbon dioxide gas cannot enter the third accommodating chamber 22 through the fourth valve port 2311, and the gas in the third accommodating chamber 22 gradually enters the first accommodating chamber 12 through the gas guide port 223 and the first gas guide channel 24. At this time, the pressure on the side of the piston 221 close to the fourth accommodating chamber 23 gradually decreases. The piston 221 pushes the ejector pin 232 again under the action of the third elastic member 222 to open the fourth valve port 2311 again. Through the above arrangement, the pressure reduction effect is achieved.

[0045] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
