Abstract
A sluice valve installation method includes attaching a housing and a work valve to a fluid pipe, opening and closing the work valve to perforate the fluid pipe to form a through-hole, and opening and closing the work valve to attach a valve cover incorporating a valve body to the housing. Opening and closing the work valve to attach the valve cover includes inserting a valve cover-side bayonet claw portion into a fitting groove portion through a claw insertion portion at a valve cover attachment/detachment position where the valve cover-side bayonet claw portion does not interfere with a housing-side bayonet claw portion to insert the valve body of the valve cover into a valve cover mounting opening portion, and rotating the valve cover with respect to the housing in a state in which the valve cover-side bayonet claw portion is fitted into the fitting groove portion.
