The purpose of the utility model is realized like this: a pressure test tool for a pipeline comprises a bent pipe, a connecting piece, a fixing piece and a sealing piece, wherein a groove is formed in the joint of the bent pipe, the connecting piece is arranged on the groove, the fixing piece is arranged on the outer side of the connecting piece, a threaded hole is formed in the fixing piece, and a bolt with a locking effect is arranged in the threaded hole; the elbow joint outer end sets up the sealing member, the sealing member passes through hex bolts fixed connection on the connecting piece.
As the utility model discloses a further preferred scheme, corresponding the position all is equipped with a plurality of screw holes on sealing member and the connecting piece, hexagon bolt runs through a plurality of screw holes and constitutes the sealing member to be connected with the connecting piece.
As a further preferred scheme of the utility model, all be equipped with the flat gasket that is used for reducing the space, increases compact structure between sealing member and the connecting piece on the hex bolts.
As a further preferable aspect of the present invention, the connecting members are two semicircular structures having the same size.
As a further preferred scheme of the utility model, mounting outside limit is equipped with two screw holes, and the bolt passes through the screw hole and blocks the connecting piece.
As the utility model discloses a further preferred scheme, scribble sealed glue between sealing member and the elbow fitting.
As a further preferred scheme of the utility model, the elbow fitting is both ends, and its both ends structure is the same.
As a further preferable aspect of the present invention, the bolt vertically passes through the threaded hole to act on the connecting member.
Compared with the prior art, the utility model discloses the beneficial effect who has as follows: the groove is formed in the outer surface of the elbow joint, namely the elbow and the groove are integrally formed, so that the connecting piece can be clamped in the groove, the occupied space is reduced, and the material cost is saved; because the flat gaskets are arranged on the hexagon bolts, the compact structure between the sealing element and the connecting piece can be increased, and meanwhile, the sealant is coated between the sealing element and the elbow joint, so that double guarantee is achieved, the sealing effect is increased, and the sealing performance is improved; because set up the screw hole outside the mounting and the bolt passes the screw hole and pushes up on the connecting piece, can be with two semi-circular connecting pieces that have the structure more firm compacter, increase intensity.
