Title: Apparatus for blocking supply of extremely low temperature medium
Inventor: TANABE NOBUO
IPC: C02F1/22
Filed: 1985-06-27
Abstract: PURPOSE:To prevent trouble at start and stop times, by providing a nozzle injecting an extremely low temp. medium in the liquid phase of a receiving can and connecting a supply pipe having an extremely low temp. medium main valve to the nozzle. CONSTITUTION:When a LNG main valve 37 is opened in starting operation, the pressure of a pressure gauge 39 rises and, after the pressure gauge 39 reached predetermined pressure, even if the nozzle main valve 35 is opened, sea water 3 is not reversely flowed and the freezing of a nozzle communication pipe 34 and a LNG supply pipe 36 due to reverse flow can be prevented. When LNG is injected toward sea water 3 in a crystallization boiler 1 from a nozzle port 27A through the communication orifice 27 of a nozzle 28, the sea water in the crystallization boiler 1 generates precipitation to form a slurry having an ice crystal stream suspended therein and said slurry is transferred to a washing and melting tank. At a stop time, both main values 35, 37 are closed to discharge LNG in the supply pipe 36 between first and second liquid seal preventing valves 38, 40 and the supply pipe 36 between the preventing values 38, 40 is filled with seal gas.

Abstract: PURPOSE: To prevent the abrasion of the contact portions through the increasing of the contact area by making guide holes set in a carriage correspond to outer diameters of all opposite guide rails and supporting other guide rails with plate springs.  
     CONSTITUTION: The area of contact portions of a carriage 2 with guide rails 3  and 4 are taken at maximum, and together with fixing the one end thereof to a  frame 8 with screw 15 in order to prevent the abrasion of the contact portion of  another end is fixed to the guide rail 4 with screw 16, whereby the carriage 2 is allowed to slide horizontally along the guide rail 3 by a first guide hole 17 being inserted into the guide rail accurately mounted to supporting plate springs 11 and 12  and the carriage 2. Further, the guide rail 3 is supported movably in forward and  rear direction by the plate springs 11 and 12, and because the force acting to the  rotative direction with the guide rail 3 as a center is regulated, the abrasion can be  prevented by the increase of the contact area.
