す。Next, the operation will be described. Since the heat-sensitive chamber 8 is filled with hot water or water below the set temperature at the initial heating of ventilation,
The temperature sensitive actuator 9 contracts as shown in FIG. 1, and the valve rod 6a moves upward due to the resultant force of the pressure acting on the valve element 6 from the valve hole 5 and the assisting force of the bias spring 12 in this embodiment. Then, the valve element 6 is separated, and the high temperature condensate is discharged through the inlet 1a, the valve hole 5 and the radial outflow holes 4b into the heat-sensitive chamber 8 and then through the porous material 13 at the outlet 1b to be discharged. Brings up internal temperature.

細かくなることにより凝縮時の騒音や振動は小さくな
る。At this time, even if the steam is mixed, the bubbles of the steam are finely crushed by the porous body 13, so that the condensation of the bubbles in the constant temperature tank A is efficiently performed, the heating efficiency is improved, and the bubbles become fine. This reduces noise and vibration during condensation.
そして、感熱室８内の湯温が徐々に高温になるにつれ
て、感温応動体９は徐々に伸長し、Ｅリング10を介して
弁棒6aを下方へ押すので、設定温度で弁子６は強制的に
着座され、弁孔５が閉じられる。Then, as the temperature of the hot water in the heat-sensitive chamber 8 gradually increases, the temperature-responsive body 9 gradually expands and pushes the valve rod 6a downward via the E-ring 10, so that the valve 6 is set at the set temperature. The seat is forcibly seated and the valve hole 5 is closed.
このように弁子６は湯温の低下と上昇とによつて開閉を
繰り返し、高温復水の供給と停止が繰り返され、恒温槽
Ａ内の湯温はほぼ一定に保たれる。In this way, the valve 6 is repeatedly opened and closed by the decrease and rise of the hot water temperature, the supply and stop of the high temperature condensate are repeated, and the hot water temperature in the constant temperature bath A is kept substantially constant.

状記憶の場合はバイアスばね12により押し戻される。Further, according to the present invention, the normal scale or the like in the constant temperature bath A is blocked by the mesh holes 13b of the porous material 13 and is prevented from flowing back into the outlet 1b. However, a fine scale that passes through the mesh holes 13b gradually flows backward and adheres to the valve element 6 and the valve hole 5 due to long-term use, causing valve leakage. At this time, when the inside of the heat-sensitive chamber 8 is heated to a temperature higher than the desired temperature (abnormal), the sudden-change heat-sensitive element 11 made of shape memory alloy, which is normally inoperative, exceeds the reverse transformation temperature to cause martensite transformation. Extend. Therefore, an overwhelmingly large force acts as the valve closing force as compared with the bimetal temperature sensitive body 9, so that the accumulated scale and the like are crushed and the valve is completely closed. After that, when the temperature in the heat-sensitive chamber falls below the transformation temperature of the shape memory alloy, it returns to the original shape by itself in the case of bidirectional shape memory, and in the case of unidirectional shape memory as in this embodiment, the bias spring. Pushed back by 12.
