Abstract
The utility model discloses a positioning flange hole check valve. The structure of the traditional check valve with one flange hole on each edge is changed to the structure that both edges at the outer side of the valve body of the check valve are correspondingly provided with four positioning flange holes. The positioning flange hole check valve is characterized in that four positioning flange holes are directly and correspondingly welded or cast on the two edges at the outer side of the valve body of the check valve. After the two edges at the outer side of the valve body of the traditional check valve are correspondingly provided with four positioning flange holes, the positioning flange hole check valve has the advantages of convenient installation and good stability, and the service life of the valve is correspondingly prolonged. The positioning flange hole check valve is characterized in that the four positioning flange holes are directly and correspondingly welded or cast on the two edges at the outer side of the valve body. The positioning flange hole check valve has the advantages that after the two edges at the outer side of the valve body of the traditional check valve are correspondingly provided with four positioning flange holes, the check valve has convenient installation and good stability, and the service life and the valve is correspondingly prolonged.
