Title (EN) NON-RETURN VALVE
(FR) CLAPET ANTI-RETOUR
(JA) 逆流防止弁
Abstract:
(EN) [Problem] To provide a non-return valve capable of suppressing the occurrence of damage such as splitting and deformation. [Solution] The non-return valve opens and closes an opening provided in a body and prevents backflow of fluid that passes through the opening, the non-return valve being provided with: a flexible base 71; and a valve part 72 connected to the base 71 in a state of being surrounded by the base 71, the valve part 72 having a thinner thickness than the thickness of the base 71 and opening and closing the opening. The valve part 72 is biased in advance toward the body by the elasticity of the base 71 and seals the opening in a normal state, and opens the opening when fluid passes through the opening in one direction.
(FR) Le problème décrit par la présente invention consiste à fournir un clapet anti-retour capable de supprimer l'apparition de dommages tels qu'une division et une déformation. La solution selon l'invention porte sur un clapet anti-retour qui ouvre et ferme une ouverture ménagée dans un corps et empêche un reflux de fluide qui passe à travers l'ouverture, le clapet anti-retour comprenant : une base flexible (71) ; et une partie de soupape (72) raccordée à la base (71) dans un état entouré par la base (71), la partie de soupape (72) présentant une épaisseur plus fine que l'épaisseur de la base (71) et ouvrant et fermant l'ouverture. La partie de soupape (72) est sollicitée à l'avance en direction du corps par l'élasticité de la base (71) et assure l'étanchéité de l'ouverture dans un état normal et ouvre l'ouverture lorsque le fluide passe à travers l'ouverture dans une direction.
(JA) 【課題】裂けや変形などの破損が生ずることを抑えることができる逆流防止弁を提供すること。 【解決手段】逆流防止弁は、本体に設けられた開口部を開閉し、開口部を通過する流体の逆流を防止する逆流防止弁であって、可撓性を有する基部71と、周囲を基部71に囲まれた状態で基部71に接続され、基部71の厚さよりも薄い厚さを有し、開口部を開閉する弁部72と、を備える。弁部72は、基部71の弾性により本体に向かって予め付勢され通常状態で開口部を密閉し、流体が開口部を一方向に通過する際に開口部を開放する。
