Fixture for detecting airtightness and water pressure of 3D printing valve body blank

The utility model discloses a 3D printing valve body blank airtightness and water pressure detection clamp comprising a sealing plate acting on a valve body port, the outer edge of the sealing plate is provided with a plurality of fixed clamping grooves, and the fixed clamping grooves are internally provided with C-shaped clamps capable of moving along the axial direction of the sealing plate. One end of the C-shaped clamp extends out of the inner side face of the sealing plate and forms a hook claw used for hooking the end edge of the valve body, the other end of the C-shaped clamp extends out of the outer side face of the sealing plate and forms a limiting part, a locking screw is screwed into the limiting part through threads, the locking screw abuts against the outer side face of the sealing plate, and therefore the extending amount of the hook claw is limited, and clamping is achieved. According to the clamp, reliable and convenient sealing of the port of the valve body is achieved, stable pressing force
