This utility model discloses a self-circulating saturated water heat extraction system, which includes a reactor metal cylinder, a steam drum jacket outside the reactor metal cylinder, a steam drum heating rod inside the steam drum jacket, and a steam drum insulation on the outside. The steam drum jacket is filled with metal packing, and a packing pressure plate is located at the top of the steam drum jacket. The packing pressure plate has multiple small holes and multiple steam guide pipes. The top of the steam drum jacket is connected to the end cap at the bottom of the tube side of the steam condenser through a steam-condensate flow pipe. The end cap at the top of the tube side has a vent, a cooling water inlet is located at the bottom of the shell side, and a cooling water outlet is located at the top of the shell side. Because the steam drum contains saturated water, even a small increase in the reactor surface temperature will locally disrupt the temperature and pressure balance of the water, causing the water in contact with the reactor surface to vaporize. Simultaneously, since water vaporization requires the reactor wall to transfer heat equivalent to the latent heat of water vaporization, the system achieves the purpose of rapidly removing the heat released by the reaction.

This invention relates to the field of valve technology and discloses a C-type wear-resistant ball valve with a non-external leakage double stuffing box system for cryogenic devices. The valve valve includes: a valve body with a horizontally oriented through-flow channel inside; a valve seat embedded in the valve body; a valve seat sealing ring on the valve seat; a C-shaped ball that mates with the valve seat in the center of the valve body's inner cavity; a valve stem connected to the upper end of the C-shaped ball; a valve cover at the upper opening of the valve body; a first packing inside the valve cover, fitted onto the outside of the valve stem; a first packing sleeve at the upper end of the first packing; a bracket at the upper end of the valve cover; a second packing inside the bracket, fitted onto the outside of the valve stem; a second packing sleeve at the upper end of the second packing; a packing pressure plate at the upper end of the second packing sleeve; and a control module electrically connected to the C-shaped ball and an operating device. The control module controls the operation of the operating device. This invention ensures reliable sealing through its double stuffing box structure.
