Float head heat-exchanger pressure test tool, comprise dummy-flange, movable tube sheets heat exchanger housing, V-type rubber seal, pressure testing mold and clamp, described dummy-flange is arranged on the stationary tubesheet end of movable tube sheets heat exchanger housing, described pressure testing mold is arranged on the floating tubesheet end of movable tube sheets heat exchanger housing by bolt and clamp, and described V-type rubber seal is arranged on inside pressure testing mold.
More excellent, offer V-type groove inside described pressure testing mold, described V-type rubber seal is arranged in V-type groove.
More excellent, described V-type groove is 2-3 bar.
More excellent, described pressure testing mold each V-type groove corresponding offers seal groove through hole, and described seal groove through hole is spot-facing.
More excellent, described clamp is forging, and clamp is fan-shaped ring, and the inner ring end face of clamp is corresponding with the periphery of pressure testing mold, and the outer shroud end of clamp is provided with annular boss.
More excellent, described clamp offers the threaded hole mated with described bolt.
More excellent, described dummy-flange and movable tube sheets heat exchanger housing junction are provided with gasket seal.
More excellent, described bolt is stud bolt, and the quantity of described clamp is identical with the quantity of bolt.
The utility model connects pressure testing mold by clamp, improves the versatility of float head heat-exchanger pressure test tool, separately adopts V-type rubber seal at floating tubesheet end, improves the sealing in pressure testing process.
