本発明は、ゴム製ダイヤフラムを用いたガス調節弁にお
いて、周囲温度の変化により、特性が変化するのを抑制
するための機構に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mechanism for suppressing changes in characteristics due to changes in ambient temperature in a gas control valve using a rubber diaphragm. .
ガス調節弁の一つとして、例えば第５図に示すガスガバ

ことにより、出力部ｊのガス圧を安定するものである。As one example of a gas control valve, there is a gas governor a shown in FIG. 5, for example. This is a diaphragm e that partitions the device body into a valve chamber C and a control chamber d.A valve body f is provided on the valve chamber C side, and a mm spring h is installed between the control screw g and the diaphragm e on the control chamber d side.
The resultant force of the force of the gas pressure at the input part i of the valve chamber C pushing the diaphragm e toward the adjustment side d, the elastic force of the adjustment spring h in the opposite direction, and the elastic force of the diaphragm e itself is mutually By moving the valve body f in a balanced manner, the gas pressure at the output section j is stabilized.
また、ガス調節弁の他の例として、前記の調節スプリン
グｈに代えて、ムービングマグネットやムービングコイ
ルを調節機構に用いたものもある。Further, as another example of the gas regulating valve, there is also one in which a moving magnet or a moving coil is used as the regulating mechanism in place of the above-mentioned regulating spring h.

によって出力部ｊのガス圧を所望の値に設定できる点が
異なる。This causes the moving net or moving coil to generate an electromagnetic force that pushes the diaphragm e toward the valve chamber C, and similarly to the case using the adjustment spring h described above, this electromagnetic force is combined with the elastic force of the diaphragm e itself. The valve body r is moved so that the resultant force balances the gas pressure at the input section i, and the gas pressure at the output section j is stabilized.The gas pressure at the output section j is adjusted to the desired value by adjusting the electromagnetic force. The difference is that it can be set to the value of .

防ぐために、例えば調節機構に特別な温度補償回路を追

い実用的でないという問題点がある。When the surrounding temperature rises, the rubber diaphragm e softens and stretches, weakening its elastic force, which weakens the force resisting the gas pressure at the input section i, and as a result, the output section j
There is a problem that the gas pressure of the gas decreases. Also,
For gas control valves that use an electromagnetic force control mechanism, there is a way to prevent this by adding a special temperature compensation circuit to the control mechanism, but this has the problem of being too expensive and impractical. .

圧のガスを出力するものである。The gas control valves 8 shown in FIGS. 1 to 3 each have a valve chamber 2.
The force of the gas pressure in the input section 12 pushing the rubber diaphragm 4 toward the adjustment chamber 3, the elastic force of the diaphragm 4 itself in the opposite direction, and the adjustment mechanism such as the adjustment spring 7 provided in the adjustment chamber 3 are combined. The valve body 5 is moved relative to the valve seat 13 so that the resultant force with the force pushing the diaphragm 4 toward the valve chamber 2 is balanced, and the gap between the valve body 5 and the valve seat 13 is changed to adjust the flow rate. The pressure is then adjusted to output gas at a constant pressure from the output section 14.

An electromagnetic force is generated to move O toward the valve chamber 2, and the resultant force of this force and the elastic force of the diaphragm 4 itself is made to oppose the gas pressure. Similarly, in the example shown in FIG. 3, an electromagnetic force is generated between the moving magnet ll and the current flowing through the coil 16, and this is utilized.

がって出力ガス圧の低下を改善することができる。In the present invention, a tension reinforcing layer 9 made of cloth or mesh is newly provided on the rubber diaphragm 4 of such a gas control valve 8, and the tension reinforcing function of this reinforcing layer 9 prevents the ambient temperature from rising. Even in this case, the elongation of the diaphragm 4 and the decrease in its elastic force can be suppressed within a certain limit, and therefore the decrease in output gas pressure can be improved.

材または網材により構成して良いのはもちろんである。The reinforcing layer 9 may be constructed by using, for example, Tetron cloth and gluing it onto one side of the diaphragm 4 as shown in FIG. In some cases, this reinforcing layer 9 may also be integrally formed, and one or more Tetoron cloths may be sandwiched inside the diaphragm 4 in the form of a sandwich, as shown in FIG. 4(b). Tetron cloth is the most suitable material for the reinforcing layer 9 because its degree of softening when the ambient temperature rises is much smaller than that of rubber, and it is also mechanically strong and inexpensive. It goes without saying that it may be constructed of any other appropriate cloth or mesh material that has similar characteristics.

ある。As described above, the temperature compensation mechanism of the gas control valve of the present invention is as follows:
In a gas control valve using a rubber diaphragm, changes in its characteristics due to changes in ambient temperature, that is, a decrease in output gas pressure when the ambient temperature rises, can be compensated for by adjusting the diaphragm without using a special temperature compensation circuit. There is an effect that this can be improved by an extremely simple means of simply providing a tension reinforcing layer made of cloth or net made of Tetoron cloth or the like.
