体７を押圧している。 A first diaphragm 5 is disposed within the outlet passage 3 so as to receive the pressure within the outlet passage 3, and the first diaphragm 5 slides in the vertical direction via a rod 6 to open the port 4. It supports a valve body 7 that adjusts opening and closing. A spring 9 is inserted between the valve body 7 and a spring receiver 8 located below the valve body 7, and presses the valve body 7 in a direction to close the port 4.
上記スプリング受け８は前端側を係止部１０で

し、出口通路３内の水圧P2を受ける。 The three-pronged valve 13 is operated by an input signal from a control device (not shown), and when the input signal is ON, the inlet passage 2 and the second diaphragm 11 communicate with each other, and the second diaphragm 11 It receives the water pressure P 1 in the passage 2. Conversely, when the input signal of the control device is OFF, the second diaphragm 11 is cut off from the inlet passage 2, communicates with the outlet passage 3, and receives the water pressure P2 in the outlet passage 3.
尚、上記三又弁１３は、オン・オフ弁に限定せ

いる。 The adjustment screw 16 can be rotated to move vertically, and the set value of the first diaphragm 5 can be changed via the spring 18. However, the pressure setting by this adjustment screw 16 is the primary one, and once the pressure is set, it is fixed except for selecting and changing the set value, and after that, the above-mentioned three-pronged valve that exclusively uses water pressure is used. 13, the setting value is changed. Further, the inside of the connecting member 15 communicates with the outside through a ventilation hole 19 formed in the peripheral wall thereof.
次にこの発明に係る水ガバナの動作について説
明する。 Next, the operation of the water governor according to the present invention will be explained.
まず、調整ネジ１６を上下に螺合移動させるこ
とによつて、スプリング１８を介して第１のダイ
アフラム５に与える設定値が定められる。 First, by screwing and moving the adjusting screw 16 up and down, a set value to be applied to the first diaphragm 5 via the spring 18 is determined.
一方図示しない出力発信源からの入力信号が供

ム５に伝達される。 On the other hand, when an input signal is supplied from an output source (not shown) and the three-pronged valve 13 is turned on, the inlet passage 2 and the second diaphragm 11 are communicated with each other.
Water pressure P 1 in the inlet passage 2 of the second diaphragm 11
is received and transmitted to the first diaphragm 5 via the spring 9.

１３に出力信号を供給し、三又弁１３をOFFの
状態に切換えると第２のダイアフラム１１は出口
通路３と連通し水圧P2を受けるので、設定値は２
段階に変更できる。 Then, in order to change the set value and supply the required amount of water at the appropriate time, an output signal is supplied from the output signal source to the three-pronged valve 13, and when the three-pronged valve 13 is turned off, the second The diaphragm 11 communicates with the outlet passage 3 and receives water pressure P2 , so the set value is 2.
Can be changed in stages.
さらに三又弁１３として制御弁を使用し、ON

れば、入口通路２内の水圧P1が与えられた第２の
ダイアフラム１１は順々に減圧した状態に設定さ
れるので、設定値は無段階的に可変できる。 Furthermore, a control valve is used as the three-pronged valve 13, and the ON
If you arbitrarily switch from the state to the OFF state, the second diaphragm 11 to which the water pressure P 1 in the inlet passage 2 is applied will be set to a state in which the pressure is sequentially reduced, so the set value will be null. Can be changed in stages.

３ａを配置した実施例である。 FIG. 2 shows another embodiment of the valve 13 and pipe 14 for introducing water pressure into the diaphragm 11, in which a pipe 14a communicating with the inlet passage 2 and a pipe 14b communicating with the outlet passage 3 are connected to the second diaphragm 11, respectively. In addition to direct communication, a forked valve 1 is connected to the pipe 14b.
This is an example in which 3a is arranged.

ける。 The forked valve 13a is also operated by an input signal from a control device (not shown), and in the ON state, the inlet passage 2 and the second diaphragm 11 communicate with each other, and the second
The diaphragm 11 of is subjected to the water pressure P 1 in the inlet passage 2 .
また逆に制御装置の入力信号がOFFの状態で

口通路３と連通する。従つて、第２のダイアフラ
ム１１はONの状態の入口通路２内の水圧P1から
OFFの状態の水圧P2まで減圧でき設定値を変更
できる。 Conversely, when the input signal of the control device is OFF, the second diaphragm 11 communicates with the inlet passage 2 and the outlet passage 3. Therefore, the second diaphragm 11 receives water from the water pressure P 1 in the inlet passage 2 in the ON state.
The water pressure can be reduced to P 2 when it is OFF, and the set value can be changed.
ここでも上記二又弁１３ａもオン・オフ弁に限
定せず、制御弁を使用すれば、設定値を無段階的
に可変できる。 Here again, the forked valve 13a is not limited to an on/off valve, and if a control valve is used, the set value can be varied steplessly.
