DEVICE TO TAKE SAMPLES OF LIQUIDS

摘要

FIELD: measurement technology. SUBSTANCE: device to samples of liquids has sampling cylinder with cover and valve to make sample leak-tight. Piston with rod fitted with stopping-disconnecting mechanism having spring-loaded fixing arm are mounted inside cylinder for interaction of fixing arm with rod. Sample-taking mechanism is provided with lower cover. Spring-loaded fixing arm is anchored in upper cover and interacts with one of cheeks. Cheeks are put on spring-loaded plungers in upper over. Pressing bearing are placed in bearings in cheeks. Valve to let in atmospheric air is mounted inside spring- loaded rod with piston in its upper part. Tail part of valve is mounted for sliding along spring-loaded pusher and for interaction with the latter at end of stroke via pin. Pin is fixed in lower part of tail part. Its end carries valve making sample leak-tight that is installed in lower cover. System of holes to let liquid in and to discharge it is located in cover. Device makes it feasible to take samples with the aid of manipulator of robotic aid which is very actual problem in environment hazardous for man. It allow samples to be taken from various depths, including shallow water up to small pools. EFFECT: expanded application field of device. 1 cl, 2 dwg
