Benefits of technology

【0008】 第1技術によると、流体導入路である一次側通路(弁体より上流側の通路)だけでなく、流体導出路である二次側通路(弁体より下流側の通路)についても、凍結した流体(以下、凍結流体と称する)を解凍することができる。すなわち、バルブ装置内の流体流路全体において、凍結流体を解凍することができる。低温環境下において流体流路内に凍結流体が生じても、凍結流体を効率的に解凍することができ、バルブ装置の機能が損なわることを抑制することができる。

Abstract

To provide a valve device capable of efficiently thawing frozen water generated in a fluid channel.SOLUTION: A valve device is equipped with a housing, a primary side passage that is provided in the housing and in which a fluid is introduced from the outside, a first lead-out portion that is provided at a downstream side end portion of the primary side passage, a secondary side passage that is provided in the housing, communicates with the first lead-out portion and extends in a different direction from the primary side passage, and leads out the fluid to the outside, a communication chamber that is provided between the first lead-out portion and the secondary side passage, and communicates with the first lead-out portion and the secondary side passage, a valve seat that is formed at the first lead-out portion, a valve body that can contact with the valve seat and opens / closes the first lead-out portion, the heater, and a heat transfer plate that is provided in the housing, extends along the primary side passage, and transfers the heat of the heater to the fluid. In the valve device, the primary side passage is formed so as to approach the secondary side passage toward the first lead-out portion side.SELECTED DRAWING: Figure 2
