タフライ弁において、弁箱下部に位置している弁
座の上流位置と直下流位置とを結ぶバイパス通路
が形成され、このバイパス通路に前記弁体の開閉
作動に応動して選択的に開閉作動するバイパス弁
が介設されていることを特徴とする異物堆積防止
装置を備えたバタフライ弁。 In a butterfly valve in which a valve seat, on which the valve body moves toward and away from the valve body, protrudes from the inner periphery of the valve box, a bypass passage is formed that connects the upstream position of the valve seat, which is located at the bottom of the valve box, and the position directly downstream of the valve seat. A butterfly valve equipped with a foreign matter accumulation prevention device, characterized in that a bypass valve is provided in the passageway and selectively opens and closes in response to the opening and closing operations of the valve body.
