FIELD: agricultural engineering. ^ SUBSTANCE: invention relates to devices for filling and/or draining liquids from containers for storage and transportation of liquid products, namely, to devices for locking liquid at bottom forced filling of container or draining, for instance, when filling section of tank with milk. Proposed device has housing connected to bottom in hole of which shutoff member is installed interacting with seat of housing and fitted on spring-loaded rod mechanically coupled with drive, and rod control mechanism. Shutoff member is installed for movement along rod vertically installed in housing along groove of length equal to length of travel of shutoff member between middle and lower positions. Travel of shutoff member by length of groove corresponds to area of through section of device. Rod is provided with stop to hold shutoff member in extreme upper position. Surface of shutoff member engaging with groove of rod is made of material featuring low sliding friction coefficient, and gasket is installed between stop of rod shutoff member and. ^ EFFECT: prevention of liquid losses at filling and draining when pump is switch off. ^ 1 dwg |
