本発明はビールなどの炭酸飲料の容器におけるガス圧を
調整するための感温式ガス圧力調整弁に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a temperature-sensitive gas pressure regulating valve for regulating gas pressure in a container for carbonated beverages such as beer.
従来、ガスを溶解した液体、たとえばビールなどの炭酸
飲料を容器中に貯蔵するに当って温度の変動があると、
内容物のガス圧が変化するために内容物を注ぎ出すとき
に発泡度が大幅に変化する現象がある。このような現象
を避けるために貯蔵容器を断熱することが行われるが、
万全な方法ではない。そこで、減圧弁を介して加圧ガス
を貯蔵容器に供給できるようにすると共に内圧が高くな
りすぎることを防止するための安全弁を設ける方法が採
られることが多い。Conventionally, when a liquid containing dissolved gas, such as a carbonated drink such as beer, is stored in a container, if there are temperature fluctuations,
There is a phenomenon in which the degree of foaming changes significantly when pouring out the contents due to changes in the gas pressure of the contents. To avoid this phenomenon, storage containers are insulated, but
It's not a foolproof method. Therefore, a method is often adopted that allows pressurized gas to be supplied to the storage container via a pressure reducing valve and also provides a safety valve to prevent the internal pressure from becoming too high.
このようなガス圧力調整方法を、たとえばビールのタン

圧弁および放出用安全弁として共に温度によって設定圧
力が変化するように構成したものを用いることによって
内圧の調整を容易に実施できるようにしようとしたもの
がある。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 devices have attempted to easily adjust the internal pressure by using a device configured such that the set pressure changes depending on the temperature.
しかしながら、このようなシステムでは、減圧弁と逃し

わせることは容易でなく、従ってまた互換性も乏しいと
いう難点がある。However, in such a system, a pressure reducing valve and a relief valve that have similar temperature-operating pressure characteristics are selected, and the operating points are set to be slightly different from each other in order to operate satisfactorily. It is not easy to find and match valves with similar temperature-operating pressure characteristics over a wide temperature range, and therefore there is also the problem of poor compatibility.
このような圧力＃ＪＩ整弁の特性の差による不便を解消
するために、減圧弁と逃し弁とを一個の弁本体内に組み

過ぎると圧力調整弁Ｄから炭酸ガスを系外に放出するよ
うになっている。ここでＦは容器Ｅに対する圧力計、Ｈ
は注ぎ出しコックである。In order to eliminate the inconvenience caused by the difference in characteristics of the pressure #JI valve, a pressure reducing valve and a relief valve are incorporated into one valve body, and these are connected by a pressure responsive mechanism connected to a single temperature sensing cylinder. Temperature-sensitive pressure regulating valves that are linked together (Fig. 4)
A pressure regulating system (Fig. 5) using this has been proposed (Utility Model Application No. 62-96172). In this pressure regulation system, carbon dioxide gas is supplied from the carbon dioxide pressure vessel A to the beer tank via the first pressure reducing valve B, pressure gauge C, and thermal pressure regulating valve D, and the internal pressure of the tank E becomes too high. The carbon dioxide gas is released from the pressure regulating valve D to the outside of the system. Here, F is the pressure gauge for container E, and H
is a pouring cock.
このような惑温式圧力調整弁においては、ビール等の容
器の温度に碁いてガス圧力の調整を行なうもので、容器
の交換のたびに感温筒の着脱作業を繰返さなければなら
ず感温筒の連結チューブが破ｔ員し易い問題がある。In such temperature-controlled pressure regulating valves, the gas pressure is adjusted based on the temperature of the beer container, etc., and the temperature-sensitive cylinder must be repeatedly attached and detached each time the container is replaced. There is a problem that the connecting tube of the cylinder is easily broken.
さらにまた、ビール等の注ぎ出し管の途中に冷却器を設
けて温度調整を行なうようにしたとき、容器の温度が低
いとガス圧力が不足し、注ぎ出し流量が少なくなるとい
う問題もある。Furthermore, when a cooler is installed in the middle of a pouring pipe for beer or the like to adjust the temperature, there is a problem that if the temperature of the container is low, the gas pressure will be insufficient and the pouring flow rate will be reduced.
そこで本発明は、容器の交換に際しても特に取付取外し

を目的とした。Therefore, the present invention has developed a temperature-sensitive gas pressure system that does not require any trouble when replacing the container and can increase the flow rate of beer, etc. by increasing the gas supply during pouring. The purpose was to provide a regulating valve.

特徴とするものである。The temperature-sensitive gas pressure regulating valve of the present invention that can achieve the above object includes a gas pressure reducing valve provided between the primary side and the secondary side, and a gas relief valve provided between the secondary side and the outside. and an automatic valve operated by a single diaphragm to adjust the gas pressure necessary to maintain the amount of dissolved gas in the liquid in the container connected to the secondary side within a predetermined range. A delivery conduit section through which the liquid can flow is provided adjacent to a thermostatic section communicating with a pressure chamber on the outer surface side of the diaphragm, and the pressure of the dissolved gas can be introduced into a pressure regulating chamber on the inner surface side of the diaphragm. A gas introduction path is provided, and the gas pressure reducing valve is opened when the temperature of the liquid increases by 1 F or the pressure of the dissolved gas decreases, and the gas relief valve is opened when the temperature of the liquid decreases or the pressure of the dissolved gas increases. It is characterized by the fact that

の変化が自動的に補正される。In the temperature-sensitive gas pressure regulating valve of the present invention, the conduit through which the fluid sent from the liquid container passes is provided adjacent to the thermostatic section, so that the pressure of the temperature-sensitive medium corresponding to the temperature of the delivered liquid is adjusted to the diaphragm. If the pressure of the dissolved gas is applied to the outside surface of the diaphragm, and the pressure of the dissolved gas is applied to the inside surface of the diaphragm, the gas pressure on the secondary side of the gas pressure regulating valve is determined by the balance of these pressures, and the pressure of dissolved gas is applied to the inside of the diaphragm. gas dissolution■

に復帰する。Furthermore, when pouring out drinks, etc., the amount of gas replenishment is automatically increased so that the pressure within the container does not drop. Furthermore, if you want to temporarily increase the gas pressure in the container to ensure the pouring flow rate, you can lower the pressure in the pressure regulating chamber by temporarily opening it. can also be increased arbitrarily. After performing such temporary pressure control, if the gas pressure inside the container is applied again to the pressure regulating chamber, the excess gas inside the container is released and the pressure returns to the previous pressure.
