The present invention relates to a temperature-type pressure regulating valve for maintaining regulation within a range.

方法が取られることが多い。BACKGROUND TECHNOLOGY Conventionally, when a liquid containing a dissolved gas, such as a carbonated drink such as beer, is stored in a container, if the temperature changes, the gas pressure of the contents changes, so when the contents are poured out. There is a phenomenon in which the degree of foaming changes drastically. In order to avoid this phenomenon, storage containers are insulated, but this is not a foolproof method. Therefore, a method is often taken in which a safety valve is provided to allow pressurized gas to be supplied to the storage container via a pressure reducing valve and to prevent the internal pressure from becoming too high.

る。Ｈは抜出しコツクである。 When applying such a gas pressure adjustment method to a beer tank, for example, it is necessary to replenish carbon dioxide gas as the content decreases, and it also functions as a pressure reducing valve for supplying carbon dioxide gas and a safety valve for releasing it. Some attempts have been made to make it easier to adjust the internal pressure by using a device configured so that the set pressure changes depending on the temperature. Such a pressure regulation system is configured as shown in FIG. 5, for example, and carbon dioxide is supplied from a carbon dioxide cylinder A to a beer tank E via a first pressure reducing valve B, a pressure gauge C, and a temperature-type pressure reducing valve D. If the internal pressure becomes too high, the temperature relief valve G
After that, carbon dioxide gas is released out of the system. Here, the first pressure reducing valve B is adjusted so that the outlet gas pressure does not exceed the allowable pressure of the tank E. H is for extraction.

For example, one having a structure as shown in Fig. 6 is used, and carbon dioxide gas can be supplied at a higher pressure to compensate for the decrease in solubility of carbon dioxide gas as the temperature increases. It's summery. That is, the pressure of the temperature-sensitive fluid in the temperature-sensitive tube D1 causes the diaphragm D2 to move between the actuating plate D3 and the connecting rod D4.
actuates to open valve body D 5 through secondary chamber D 6
When the pressure increases, valve body D5 is operated to close. In addition, D 7 is the valve and the valve spring for closing.
D 8 is the spindle for setting the operating pressure of the valve.

動圧力を設定するためのスピンドルである。 Further, the temperature relief valve G of the above system has a structure as shown in FIG. 7, for example, and is designed to prevent carbon dioxide from increasing in solubility as the temperature decreases. It is designed to release water and lower the pressure. In other words, when the pressure of the temperature-sensitive fluid inside the temperature-sensing cylinder G1 decreases, the diaphragm G2
The actuating plate G3 , which had been pushed by the valve spring G4 , is pushed in the opposite direction via the actuating rod G5 , and operates to open the valve body G6 , allowing the gas in the primary chamber G0 to escape through the relief port G8. flowing to,
If the pressure in the primary chamber G7 decreases, the valve body G6 will open as a relief port.
Operates to close G 8 . Note that G9 is a spindle for setting the operating pressure of the valve.

設定をやり直す必要があり、至つて不便である。 However, in such a system, satisfactory operation can only be achieved by selecting pressure reducing valves D and relief valves G with similar temperature-operating pressure characteristics, setting the operating points slightly different from each other, and combining them. However, it is not easy to find and combine valves with similar temperature-operating pressure characteristics over a wide temperature range (Fig. 4a), and there is also the problem of poor compatibility. be. If you try to use a combination of valves with different temperature-operating pressure characteristics, as shown in Figure 4 b or c, if you adjust the gas pressure to an appropriate level at a certain temperature, a pressure difference will open up at other temperatures. So much so that it becomes impossible to adjustb,
Alternatively, the pressure difference may be reversed, causing gas to constantly flow out, and the pressure setting of each valve must be reset depending on the operating temperature, which is extremely inconvenient.

４が閉じて炭酸ガスの補給が停止する。 When the pressure regulating valve of the present invention is incorporated into such a system, high-pressure carbon dioxide gas is supplied to the primary chamber 3a, and the secondary chamber 3c communicates with the beer tank. When the pressure in the beer tank is low, use pressure equalization path 3.
The pressure in the pressure regulating chamber 3e communicated by d is also low, and the movement of the actuating plate 6 pushed by the diaphragm 2 is caused by the second valve element 8, the second valve seat 9a, and the connecting rod 11. The signal is transmitted to the first valve body receiver 4a, and the first valve body 4
and the first valve seat 3b are opened and carbon dioxide gas flows into the secondary chamber 3c.
After that, it is refilled into the beer tank. Then, when the pressure in the beer tank reaches the set pressure, the first valve body 4 closes and replenishment of carbon dioxide gas is stopped.

る。 When the temperature of the beer tank rises in this state, the pressure of the temperature-sensitive fluid in the temperature-sensing cylinder 1 increases, the force applied to the diaphragm 2 increases, and the actuating plate 6 is pushed. On the other hand, since the solubility of carbon dioxide gas in beer decreases, the pressure inside the beer tank E also increases, but at normal beer storage temperatures, the increase in pressure due to the decrease in the solubility of carbon dioxide gas is relatively small, so the diaphragm 2 The actuating plate 6 is moved so as to compress the first spring 5 and the second spring 7. As a result, as the temperature rises, carbon dioxide gas is forced into tank E, thereby compensating for the decrease in solubility of carbon dioxide gas. Then, after the pressure within the tank E increases in proportion to the temperature, the first valve body 4 closes.
この後、ビールタンクＥの温度が低下すると、

ヤフラム２は元へ戻つて逃し弁が閉止する。 After this, when the temperature of beer tank E decreases,
Since the pressure drop of the temperature-sensitive fluid in the temperature-sensing cylinder 1 is more significant than the pressure drop due to the increase in the solubility of carbon dioxide in the beer tank E, the force of the diaphragm 2 pushing the actuating plate 6 becomes smaller, and the actuating plate 6 Pushed by the spring, it moves upward together with the second valve body 8. On the other hand, the first valve element 4 remains seated on the first valve seat 3b, and the first valve element receiver 4a and the relief valve body 9 connected thereto by the connecting rod 11 do not move, so the second valve element 4 remains seated on the first valve seat 3b. The body 8 is separated from the second valve seat 9a, and the carbon dioxide in the tank E flows from the secondary chamber 3c to the pressure equalization path 3d, the pressure adjustment chamber 3e,
The gas discharge port 1 passes through the second valve seat 9a and the relief passage 9b.
0 to the outside. As a result, the pressure in the tank E, and therefore the pressure in the pressure regulating chamber 3e, decreases, the diaphragm 2 returns to its original position, and the relief valve closes.

It is possible to adjust the difference in operating pressure between the relief valve composed of the second valve body 8 and the second valve seat 9a, and also adjust the second spindle 7b to
By moving the spring receiver up and down and adjusting the pressing force of the second spring 7, the operating pressure of the relief valve can be set. Therefore, tank E
When trying to reset the pressure to a higher value, set the

できる特長を有する。Effects of the invention The temperature-type pressure regulating valve of the invention has the functions of a pressure reducing valve and a relief valve in one valve.
These pressure reducing valves and relief valves are operated in conjunction with each other to adjust the pressure by means of temperature-sensitive cylinders.The higher the temperature of the temperature-sensing cylinder, the higher the regulated pressure is, and the lower the temperature, the higher the regulated pressure. It has an operating characteristic of controlling by moving it lower. Therefore, it can not only be used advantageously for adjusting the carbon dioxide pressure in beer storage containers, but also has the feature that the operating pressure can be arbitrarily reset while maintaining the difference between the operating pressures of the pressure reducing valve and the relief valve. .
