Description

TECHNICAL FIELD

[0001] The utility model relates to beer filling technology field, specifically at high pressure for the gas control pressure stabilizing valve of froth. BACKGROUND

[0002] For the filling of beer, the solution filled in the interior of the glass bottle is a predetermined amount, and is usually less than the capacity of the glass bottle, therefore, after filling, the liquid level in the glass bottle is lower than the bottle mouth, at this time, there is a section of air from the liquid level to the upper end of the bottle mouth, before capping the glass bottle, high pressure water line with a diameter of about 0.2 millimeters is heated to hit the beer to generate beer froth, and the last air in the neck of the beer bottle is removed, so that there is no oxygen after capping the beer.

[0003] Because the filling speed is variable in the actual beer filling process, sometimes fast and sometimes slow, that is, the time of the glass bottle being hit by the high pressure water line is variable, therefore, it is necessary to strictly control the pressure when the high pressure water line is hit, if the pressure is too large, the froth will overflow from the bottle, causing less beer, if the pressure is too small, it is not possible to remove all the air, therefore, when the filling machine is slow, the froth pressure required is also low, when the filling machine is fast, the froth pressure also needs to be increased.

[0004] However, the response time of this process is very short, because the froth pressure can reach 16 kilograms at the highest, and the aperture of the high pressure water line is only 0.2 millimeters, which is very small, therefore, the accuracy of the response requirement is very high, at present, the control scheme through the proportional valve often causes less beer and high beer loss due to unstable froth pressure.

[0023] In order to better understand the technical content of the present application, specific embodiments are described below with reference to the accompanying drawings.

[0024] In combination with Figure 1 and Figure 2 shown, the present application proposes a gas control pressure stabilizing valve 100 for high-pressure foam, the water inlet is connected to a water medium pressure source 200, the water outlet is connected to a nozzle 400, high-pressure water is injected into the glass bottle through the nozzle, so that the internal solution A generates foam B, and the air is driven out. Due to the difference in conveying speed of the conveying belt, each glass bottle spends different time under the nozzle 400, therefore, the pressure of the nozzle 400 needs to be adjusted according to the conveying speed to ensure that the foam B reaches the bottle mouth.

[0025] In combination with Figure 2 shown, the gas control pressure stabilizing valve mainly includes a valve seat 10, a cylinder seat 20 and a cylinder cover 30, the valve seat 10, the cylinder seat 20 and the cylinder cover 30 are fixedly connected with each other, the valve seat 10 is internally provided with a flow guide channel 202 connecting the liquid inlet 201 and the liquid outlet 203, the flow guide channel 202 is provided with a valve plug 12, the valve plug 12 is used to separate the flow guide channel into a first part and a second part.

[0026] Among them, the first part is in communication with the liquid inlet 201, the second part is in communication with the liquid outlet 203, and the valve plug 12 can control the communication state of the first part and the second part.

[0027] That is, by controlling the position of the valve plug 12, the conduction state of the first part and the second part of the flow guide channel 202 can be controlled, when the opening degree of the valve plug 12 is large, the pressure of the liquid outlet 203 is large, when the opening degree of the valve plug 12 is small, the pressure of the liquid outlet 203 is small, therefore, by controlling the opening degree position of the valve plug 12, the liquid outlet pressure of the liquid outlet 203 can be controlled.

[0028] Specifically, the valve plug 12 is in sliding connection with the valve seat 10, and the sliding direction of the valve plug 12 is parallel to the assembly direction of the valve seat 10 and the cylinder block 20. The bottom of the valve plug 12 is provided with a guide rod 13, and the outside of the guide rod 13 is provided with a spring 14, which has a tendency to push the valve plug 12 to open.

[0029] As shown in Figure 2 , when the valve plug 12 moves towards the cylinder block 20, the opening of the valve plug 12 increases, and when the valve plug 12 moves away from the cylinder block 20, the opening of the valve plug 12 decreases.

[0030] In an optional embodiment, the cylinder block 20 is connected to the valve seat 10, and the cylinder head 30 is connected to the cylinder block 20, and the first cavity 101 is formed between the cylinder block 20 and the cylinder head 30.

[0031] In this way, the first cavity 101 can be provided with pressure by an external gas source, so that one side of the valve plug 12 is water pressure and the other side is air pressure. By adjusting the size of the air pressure, the opening of the valve plug 12 can be changed, that is, the opening of the valve plug 12 can be quickly responded and accurately maintained at the response opening position.

[0032] Among them, the valve seat 10 is provided with a first diaphragm 11 on the side facing the cylinder block 20, the valve plug 12 is attached to the first diaphragm 11, a second cavity 103 is formed between the cylinder block 20 and the valve seat 10, and the first cavity 101 and the second cavity 103 are communicated.

[0033] As shown in Figure 2 , the liquid inlet 201 is connected to the water medium pressure source 200, so that the liquid inlet 201 has a first pressure, the first cavity 101 is connected to the gas medium pressure source 300, so that the second cavity 103 has a second pressure, and the opening of the valve plug 12 is set to be adjusted according to the difference between the first pressure and the second pressure, so that the liquid outlet pressure of the liquid outlet 203 is at a preset value.

[0034] It should be understood that one side of the valve plug 12 is a water medium, and one side of the first diaphragm 11 is an air medium. When the water medium pressure is greater than the pressure of the air medium, the valve plug 12 is opened, and the high-pressure water flow enters the nozzle 400 from the liquid inlet 201-liquid guide channel 202-liquid outlet 203. By changing the pressure in the second cavity 103, the opening of the valve plug 12 changes to adjust the output pressure of the nozzle 400.

[0035] Optionally, the first cavity 101 is connected to the gas medium pressure source 300 through a proportional valve 40, and the gas medium pressure source 300 includes a compressed air source 50. The proportional valve 40 is used to control the air intake amount in the first cavity 101.

[0036] Thus, the pressure of the second cavity 103 can be controlled by the proportional valve 40, and fast response is achieved, when the pressure of the first cavity 101 needs to be increased, the proportional valve 40 allows more gas to enter the second cavity 103, so that the pressure of the first cavity 101 increases, when the pressure of the second cavity 103 needs to be reduced, the proportional valve 40 allows less gas to enter the second cavity 103, and more gas is discharged to the outside, so that the pressure of the second cavity 103 is reduced.

[0037] Specifically, by monitoring the pressure change in the second cavity 103 in real time, the parameters of the proportional valve 40 are adjusted as needed.

[0038] In an optional embodiment, the cylinder base 20 and the cylinder cover 30 are fixedly connected by bolts, the inner wall of the cylinder cover 30 is provided with a second diaphragm, and the cylinder cover 30 is provided with a gas pipe joint, the first end of the gas pipe joint extends to the outer wall of the cylinder cover 30, and the second end extends to the first cavity 101 through the second diaphragm.

[0039] Among them, the proportional valve 40 is connected to the gas pipe joint through the gas pipe, and gas is input into the first cavity 101.

[0040] In an optional embodiment, the valve seat 10 and the cylinder base 20 are threadedly connected, and when the valve seat 10 and the cylinder base 20 are connected, the first cavity 101 and the second cavity 103 form a sealed cavity. To ensure reliable sealing, the gas entering the second cavity 103 through the control of the proportional valve 40 can ensure the stability and accuracy of the pressure.

[0041] In an optional embodiment, the first diaphragm 11 is a stainless steel diaphragm, which can be deformed, and when the opening of the valve plug 12 changes, the stainless steel diaphragm deforms, so that the opening of the valve plug 12 changes according to the change of the gas pressure while the strength is ensured.

[0042] In combination with the above embodiments, the gas control pressure stabilizing valve divides the valve body into two independent spaces by the diaphragm, the bottom valve body can pass through high-pressure water, the top cylinder base can pass through high-pressure gas through the proportional valve, and the valve plug is kept at a specific position under the double action of water pressure and gas pressure, that is, kept at a suitable opening position. By adjusting the input gas pressure, the water pressure output by the valve body can be changed, and the response speed is fast through the gas pressure adjustment mode. On the basis of a large pressure adjustment range, the valve plug can also ensure a reliable opening position, realizing the advantages of fast response, high precision and large pressure adjustment range.

[0043] Although the utility model has disclosed as above with preferable embodiments, it is not used to limit the utility model. Those skilled in the art to which the utility model belongs can make various changes and decorations without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model is accurate according to the definition of the claims.
