Document Type and Number:
WIPO Patent Application WO/2020/049879
Kind Code:
A1
Abstract:
Provided are an installation method and an installation device for a fluid control device, with which the positional accuracy of a valve body inserted into a hole formed in a fluid pipe in a case can be improved, controllability of a fluid in the pipe can be increased, construction equipment such as a flow control valve installation device and an operation valve device can be made more compact and lightweight, and the cost thereof can be reduced. In this installation method, in which a fluid control device (having at least a case 5 installed in a sealed state on a fluid pipe 1, and a flow control valve 10 equipped with a valve casing 12 and a valve body 11 that can be inserted into a hole 1b formed in the fluid pipe 1 in the case 5) is installed in a continuous flow state, an operation valve device 3 equipped with an operation valve body 31 for portioning the interior of the case 5 in an openable/closable manner is attached to an opening 5b formed in a neck portion 5d of the case 5, the operation valve body 31 is opened while an open end portion 5c formed in the neck portion 5d is surrounded in a sealable manner, and the fluid control valve 10, which communicates with the interior of the case 5 in a sealed state, is inserted from the open end portion 5c to an installation position at which the tip end of the valve casing 12 of the flow control valve 10 is inserted beyond the opening 5b of the neck portion 5d, thereby sealing the interval between the peripheral surface of the valve casing 12 and the peripheral surface of the neck portion 5d by means of an annular sealing member 21 in the installation position.
