The utility model discloses a pressure stabilizing pipeline for a water pressure test of an air storage tank, and relates to the technical field of pressure containers. The input end of the first stop valve is connected to the output end of the pressure test pump, and the output end is connected to the input end of the first pipeline; the output end of the first pipeline is connected to the input end of the surge tank assembly; the output end of the surge tank assembly is connected to the input end of the second pipeline; the output end of the second pipeline is connected to the input end of the second stop valve; the output end of the second stop valve is connected to the water injection port of the air storage tank; the piezometric tube is of a bent buffer structure, one end of the piezometric tube is fixedly connected to the top of the surge tank assembly, and the other end of the piezometric tube is detachably connected to the pressure gauge. Therefore, the pressure change generated by the pressure test pump can be effectively buffered, and the test pressure is always maintained in the preset range, so that the risks of equipment damage and process failure possibly caused by pressure fluctuation are reduced.

The utility model discloses a cement strength anti -break testing machine relates to cement performance test field, including equipment main part, equipment main part top one side is provided with the pressure -bending detection mechanism, is provided with the pressurizing mechanism in equipment main part, and the pressurizing mechanism includes elevating support, and the elevating support is rotationally connected with worm wheel, and the elevating support front side is fixed with second motor, and second motor output is fixed with worm, and worm is engaged with worm wheel, and the middle screw thread of worm wheel is connected with elevating stud, and the bottom hinged of equipment main part has pressurizing lever, and two connecting sliding blocks are slidably connected on pressurizing lever, and connecting sliding block is hinged with elevating stud, and another connecting sliding block is connected with pressure -bending detection mechanism. Advantageous effects lie in: second motor drives elevating stud to go up and down through worm and worm wheel, and elevating stud drives force transmission vertical pole to go up through pressurizing lever, and can pressurize cement test block like this, utilizes the big transmission ratio and self -locking characteristic of worm and worm wheel, can fine control pressure and the stability of pressure.
