a pump case pressure-proof type hydrostatic test tool comprises an inlet end flange sealing cover plate, a pressure-proof support column, a connecting end sealing cover plate and an outlet end flange sealing cover plate, wherein the inlet end of a tested workpiece is fixed on the inlet end flange sealing cover plate through four first screws and is axially sealed, the four first screws are fixed through first nuts, the outlet end of the tested workpiece is fixed on the outlet end flange sealing cover plate through second screws, the axial sealing is adopted, the four second screws are fixed through second nuts, a water injection hole is formed in the center of the outlet end flange sealing cover plate, and the water injection hole is used as a pressurizing hole;
the link seals up the clearance fit location of apron and the link of being surveyed the work piece through the hole axle, compresses tightly through the top jar of pressure testing machine, adopts radial seal, the exhaust hole is seted up at the center of the sealed apron of link, the below of the sealed apron of link is equipped with prevents pressing the support column, prevent pressing the support column and be fixed in the inner chamber of being surveyed the work piece, prevent pressing the support column and be by one section bar machine-shaping that is greater than exhaust hole aperture, and the both ends terminal surface is opened there is the tye, and the exhaust hole is connected to one end, and the water injection hole is.
Preferably, a flat gasket is arranged between the second nut and the outlet end flange sealing cover plate.
Preferably, a spring washer is arranged between the first nut and the inlet end flange sealing cover plate.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a top jar compresses tightly the sealed apron of pump case link, prevents the effect of pressing the support column because of radial seal and inner chamber, and the product is atress not, and the power that the top jar produced is whole to be fit for batch production and use on the frock through preventing pressing the support column conduction, effectively avoids leading to the product to warp to scrap because of top jar pressure, improves the product quality qualification rate.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
