Abstract

PURPOSE: To obtain the high performance sealing operating elastic force to the sealing surface of the armored body, by fitting a check valve body made of flexible material in wring fit in the hard armored body formed with a tapered or arc surface for a part of circumferential surface of the fitting inner wall.
CONSTITUTION: An annular fitting 5 is fitted if the opening at the top surface of the tank 3. An armored body 6 with an air inlet 7 is fitted with a flange 6 provided around the center of its outer surface in the fitting 5, A projection 5' in the inner surface of the fitting 5 and a concave portion on the outer surface of the armored body 6 are fitted. While a check valve 11 is made of flexible material, a valve installing plate 13' with a through hole 13" in the upper groove is fitted, a pressure response valve 13 is fitted in the center inlet of the valve installing plate 13', a lower portion separated with the valve installing plate 13' is used for an inner pressure chamber 12. The check valve body 11 is fitted in the armored body 6 in wring fit, an upper portion of the check valve body 11 is contracted in deformation by the tapered sealing portion of the armored body 6, and sealing operation can be obtained.
