Description

Technical Field

[0001] This utility model relates to the field of check valve body positioning technology, and in particular to a positioning fixture for a check valve body. Background Technology

[0002] Existing check valve body positioning fixtures are mostly used for fixing the check valve during installation. However, they are difficult to adjust the installation position and angle of the check valve during installation, increasing the installation difficulty. A Chinese patent discloses a "Check Valve Body and Valve Plate Drilling and Positioning Fixture" (application number CN202020937929.8), which includes a mounting base with a detachable mounting block. The mounting block has a first positioning block that fits against the inner wall of the external valve body. A second positioning block for positioning the external valve plate is slidably mounted on the first positioning block. The second positioning block has a positioning recess that mates with the mounting protrusion of the external valve plate. Above the positioning recess is a positioning element that engages with the mounting protrusion of the external valve plate to reserve an installation position for the external sealing plate. However, the fixture is difficult to adjust the installation position and angle of the valve body, lacking flexibility. Utility Model Content
