エツクバルブ。 A valve case having an inflow port is formed with a valve chamber that communicates with the inflow port via a valve seat, and also has a cylindrical guide tube that guides the spherical valve body relative to the valve seat in an opening/closing direction. A lid protruding around the valve seat and having an outlet communicating with the valve chamber is assembled to the open end of the valve case,
Furthermore, a coil spring is disposed in the guide tube to urge the valve element against the valve seat with a predetermined pressing force, and the coil spring has a smaller diameter than the inner diameter of the guide tube in the valve case. A check valve characterized in that it is provided with a spring guide part that regulates the inclination of the check valve.
