Abstract

The utility model discloses a quick opening fixture used for U-shaped heat exchange tube pressure testing. The quick opening fixture comprises a bottom die which is arranged on a bottom base seat and is provided with a bottom groove. The bottom of an upper die above the bottom die is provided with an upper groove. A connecting block with a bolt hole is arranged above the upper die. A fastening bolt is arranged in the bolt hole, and a protruding block at the lower end of the fastening bolt is movably clamped in a concave cavity in the top of the upper die. One end of a circular arc fixedly connected with the connecting block is hinged to one side of the bottom base seat. The other end of the circular arc is provided with a lower clamping hook. A circular-arc-shaped buckling ring is hinged to the other side of the bottom base seat. The other end of the circular-arc-shaped buckling ring is provided with an upper clamping hook. When the upper clamping hook is buckled onto the lower clamping hook, the fastening bolt is rotated to enable the upper groove to be buckled with the bottom groove, so that a U-shaped heat exchange tube can be clamped. A fixing supporting frame with a screw rod is further arranged on the bottom base seat. A head part of the screw rod is fixedly provided with a plug. An orifice of the U-shaped heat exchange tube clamped by the upper groove and the bottom groove can be blocked after the screw rod is rotated.

Further, the pressure testing of aforesaid U-shaped heat exchanger tube is with opening soon fixture, and wherein, the afterbody of described screw rod is provided with handle.
The utility model has the advantages that: simple and practical, the clamping of U-shaped heat exchanger tube and dismounting be unusual rapid and convenient all, thereby greatly improved the operating efficiency of pressure testing test.
Accompanying drawing explanation
Fig. 1 is that U-shaped heat exchanger tube pressure testing described in the utility model is with opening soon the structural representation of fixture.
Fig. 2 is the structural representation of the left apparent direction of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, the pressure testing of U-shaped heat exchanger tube is with opening soon fixture, comprise: bottom base 1, in bottom base 1, be fixedly installed bed die 2, on bed die 2, be provided with bottom groove recessed down 21, the top of bed die 2 is provided with patrix 3, the bottom of patrix 3 is provided with the recessed upper grooves 31 that makes progress, after bottom groove 21 is involutory with upper grooves 31, can clamp U-shaped heat exchanger tube 9, the top of patrix 3 is provided with contiguous block 5, in contiguous block 5, run through from top to bottom and be provided with bolt hole 51, fastening bolt 6 is arranged in bolt hole 51, the lower end projection 61 of fastening bolt 6 is movably connected in the Reentrant Cavity 41 on the fixed block 4 that is fixed on patrix 3 tops, making between fastening bolt 6 and patrix 3 can only radial rotating and can not move axially, contiguous block 5 is fixedly connected on circular arc snap ring 7, one end of circular arc snap ring 7 is hinged on a side of bottom base 1, the other end of circular arc snap ring 7 is provided with the upwards lower grab 71 of bending, the opposite side of bottom base 1 is provided with circular arc clasp 8, one end of circular arc clasp 8 is hinged in bottom base 1, the other end of circular arc clasp 8 is provided with the upper grab 81 of downward bending, when the upper grab 81 on circular arc clasp 8 is held on the lower grab 71 on circular arc snap ring 7, rotate fastening bolt 6 can make the upper grooves 31 of patrix 3 and the bottom groove 21 of bed die 2 involutory and clamp U-shaped heat exchanger tube 9, in bottom base 1, be also provided with fixing support rack 10, on fixing support rack 10, be provided with screw rod 11, the head of screw rod 11 is fixedly installed plug 12, rotating screw bolt 11 can make plug 12 move forward until shutoff at the mouth of pipe of the U-shaped heat exchanger tube 9 being clamped by upper grooves 31 and bottom groove 21.In order to facilitate rotating screw bolt 11, at the afterbody of screw rod 11, be provided with handle 13.
