The utility model discloses a regulating valve and cooking utensil, the regulating valve includes valve body and valve seat, the valve seat is equipped with the air inlet hole, at least part of valve body is located in the valve seat, the valve body is equipped with the first air outlet hole and the second air outlet hole of interval arrangement, the regulating valve still includes the supplementary airflow channel, the first air outlet hole is linked together with the air inlet hole, and the second air outlet hole is linked together with the air inlet hole through the supplementary airflow channel. The regulating valve of utility model embodiment is good in spill-proof effect, and high in safety.

The utility model relates to the technical field of temperature uniformizing plates, and particularly provides a temperature uniformizing plate with a specially arranged wick, which comprises an upper cover plate, a lower cover plate and a lower cover plate, the upper liquid absorbing core is arranged in the upper accommodating groove; a plurality of upper fixing holes are formed in the upper liquid absorbing core; the lower liquid absorbing core is provided with a plurality of lower fixing holes which are in one-to-one correspondence with the upper fixing holes; the lower cover plate is provided with a lower accommodating groove, and the lower liquid absorbing core is arranged in the lower accommodating groove; the plurality of backflow supporting columns are arranged in the plurality of lower fixing holes and the plurality of upper fixing holes; the two ends of the backflow supporting columns abut against the upper cover plate and the lower cover plate respectively. A multi-dimensional channel is constructed through the axial backflow gaps and the radial backflow gaps, the capillary suction force of the backflow supporting columns is enhanced, a working medium evaporated and rising to the upper cover plate in the heating area can be efficiently drained to the heating area of the lower cover plate, rapid circulation is formed, and therefore the heat resistance is remarkably reduced, and the temperature equalizing capacity is improved; the problem that a traditional columnar supporting structure can only provide mechanical supporting and cannot accelerate working medium backflow is solved.

The utility model discloses a tester for the wet density flow change rate of foam light soil, and belongs to the technical field of buildings. The slurry cylinder is provided with a containing cavity, a first pipeline connector and a second pipeline connector, and the first pipeline connector and the second pipeline connector are arranged at the bottom of the slurry cylinder; the hose pump comprises a suction inlet and a discharge outlet, a feeding pipe is arranged between the discharge outlet and the first pipeline connector, and a discharging pipe is arranged between the suction inlet and the second pipeline connector. One end of the supporting pipe is communicated with the feeding pipe through the first pipeline connector, the other end of the supporting pipe penetrates through the discharging disc, and a backflow gap is reserved between the discharging disc and the slurry cylinder. The device can effectively simulate the phenomenon that foam floats on the surface and slurry sinks into the bottom in the construction process of foam light soil, so that more accurate data support is provided for construction quality control.
