When replacing the existing valve, first, the lifting member is attached to the existing valve, and the lower cover body is arranged under the water supply pipe line near the valve including the existing valve. Next, the replacement valve is housed in the lower cover body, and the connection between the existing valve and the water supply pipe with a bolt or the like is released. Next, the upper cover body is attached to the lower cover body from above so that the water supply pipe line is sandwiched. As a result, the surroundings of the existing valve are watertightly covered by the upper and lower cover bodies. Next, the existing valve is hoisted by the hoisting member, and the replacement valve is moved by the driving member to the mark so that the axes are aligned. After the arrangement, the pipe joint is extended by the actuating member provided on the replacement valve, and the opening surfaces on both sides thereof are brought into contact with the opening surface of the pipe line. After the contact, the drain valve is opened to drain the water in the upper and lower cover bodies to the outside. next,
Remove the upper cover from the lower cover and connect the replacement valve and the water supply line with bolts. After that, if the lower cover body is removed, the replacement work is completed. In the above, the water in the water supply line tries to flow out from between the existing valves that have been removed, but the upper and lower cover bodies prevent the water from leaking to the outside, and therefore the existing valve can be opened without water interruption. It can be replaced.
