PROBLEM TO BE SOLVED: To provide a hot water passage, a water passage, a mixed water passage, a hot water side sheet portion, a water side sheet portion, the hot water side sheet portion, and water depending on the position between the hot water side sheet portion and the water side sheet portion. It consists of a spool-shaped mixing valve that determines the mixing ratio of hot water supplied from the water passage, and a temperature-sensitive drive element that drives the mixing valve depending on the temperature of the hot water mixed water. The unit body forming a part of the water passage is arranged on the inner peripheral portion of the spool-shaped mixing valve, and the hot water passage and the water passage are from the inner peripheral portion to the outer peripheral portion of the spool-shaped mixing valve. Since the spool-shaped mixing valve is configured to communicate with the mixed water passage at the outer peripheral portion of the spool-shaped mixing valve, the outer diameter of the spool-shaped mixing valve is large and the valve stroke is small even with the same unit outer diameter as the conventional one. By being able to do so, good temperature control performance can be obtained.
湯通水路、水通水路、混合水通水路、湯側シート部、水側シート部、前記湯側シート部、水側シート部間の位置に応じ、前記湯通水路、水通水路より供給される湯水の混合比を決定するスプール状の混合弁、湯水混合水の温度に依存し前記混合弁を駆動する感温駆動素子より成り、前記湯側シート部、水側シートが別体であり、前記湯側シート部と水側シートの距離が組立て時に微調整可能であるため、弁ストロークのばらつきを小さくすることができ、ユニット部の圧力損失や温度調整性能のばらつきも小さくできる。
It is supplied from the hot water passage, the water passage, the mixed water passage, the hot water side seat part, the water side seat part, the hot water side seat part, and the water side seat part according to the position between the hot water side seat part and the water side seat part. that the hot and cold water mixing ratio spool-like mixing valve of determining, depending on the temperature of the hot and cold water mixing water consists heat sensing drive element for driving the mixing valve, the hot water side sheet portion, the water-side sheet is separate, Since the distance between the hot water side sheet and the water side sheet can be finely adjusted at the time of assembly, the variation in the valve stroke can be reduced, and the pressure loss of the unit portion and the variation in the temperature adjustment performance can also be reduced.
