INCREASING THE EFFICIENCY OF SHUT-OFF AND CONTROL VALVES IN WATER SUPPLY SYSTEMS OF AGRICULTURAL ENTERPRISES
The role of water resources and the efficiency of their use in the national economy are considered. An analysis of the operation of elements of pipeline fittings is presented. It is shown that today the efficiency of the use of water resources in the agro-industrial complex leaves much to be desired. The main impact on the efficiency of the use of water resources is provided by water losses during transportation and the low control ability of pipeline valves. On the example of currently widely used elements of shut-off and control valves: valves and gate valves, it is shown that the efficiency of the work of shut-off and control valves has a decisive influence on the efficiency of the entire pipeline. Therefore, the main reason for unproductive water consumption is not the attitude of consumers to save water, but first of all, this is due to technical conditions. Obviously, in order to reduce water consumption, it is necessary to develop new designs of water fittings that can meet the requirements of control capacity. Based on the research, the authors believe that one of the ways to improve the efficiency of shut-off and control valves can be the use of a valve design with preliminary hydraulic control.
