弁の防振装置。 The valve body is housed in a valve box attached to the lower part of the valve body via a relay pipe, and the valve stem, which is inserted from the valve body to the valve body via the relay pipe, is composed of an upper valve stem and a lower valve stem. A long-shaft type in which an upper connecting part that bendably connects the valve stem and the lower valve stem is provided inside the valve body, and a lower connecting part that bendably connects the lower valve stem and the valve body is provided inside the valve box. In a needle valve, vibration isolating rings are installed at two locations on the outer diameter surface of the upper and lower ends of the lower valve stem, and these are brought into contact with the inner diameter surface of the valve body and the inner diameter surface of the valve box, respectively, and the vibration isolation rings are attached to the upper and lower ends of the lower valve stem. A vibration isolating device for a long-shaft needle valve, characterized in that vibration isolating rings are attached to the outer diameter surface of the valve body at two locations, and these rings are brought into contact with the inner diameter surface of the valve body.
