Abstract
PURPOSE: To enable a flow direction of a fluid to be changed by an automatic operation and enable a sure action to be gained as well as enable a loss of flow pressure in a cross section of a laying pipe to be decreased.
CONSTITUTION: An automatic switching-valve V is composed of a drive unit 1, control change-over unit 2 and cylinder part 3, said drive unit 1 being composed of a geared motor 11 with a brake, speed reducer 12, main gear 14 and fitting plate 15. Said change-over unit 2 is formed of a control member 25 consisting of an electrical control mechanism which generates a signal to start and stop said motor 11 on receipt of signals from limit switches 24a, 24b. As cylinder valves 37a, 37b are situated on valve seats 38b, 38d when a sand type filter operates to filter, raw water in a pool may be sent to a haircatcher C through an operating pump and impurities of large size may be eliminated. Then the raw water flowing out of an opening 32 may be filtered through a filter bed.
