Fluororesin flowmeter sealing device

The invention discloses a fluororesin flow meter sealing device which comprises a fluororesin cover and a fluororesin body, the upper portion of the fluororesin body is open, a fluid containing part is formed in the fluororesin body, an insertion part is arranged at the bottom of the fluororesin cover, the insertion part is combined in the fluid containing part, and an O-shaped pad insertion hole is formed in the insertion part. And an O-shaped pad is arranged in the O-shaped pad insertion hole. The purpose of the present invention is to provide a sealing device for a fluororesin flow meter, in which an insertion part for forming an O-pad is extended from the lower part of a cover, and the open upper part of a body is closed, thereby preventing the generation of a gap due to a temperature change, and preventing liquid leakage. 本发明公开了一种氟树脂流量计密封装置，包括：氟树脂盖、氟树脂本体，所述氟树脂本体的上部开放，内部形成有流体收容部，所述氟树脂盖的底部配置有插入部，所述插入部结合于流体收容部内，并且所述插入部上具有O型垫插孔，所述O型垫插孔内配置有O型垫。本发明的目的在于提供一种氟树脂流量计密封装置，通过在盖的下部延长形成供O型垫形成的插入部，封闭本体的开放上部，防止因温度变化而产生间
