SOLUTION: A deaerator comprises a base unit 2 operating feed water, a deaeration unit 3 of a dissolved gas in raw water, a control unit 4 performing control operation, and a pump unit 5 equipped with a vacuum pump. The aeration unit 3 is arranged between the base unit 2 and the control unit 4, and the pump unit 5 is arranged below the base unit 2 and the deaeration unit 3. The base nut 2 is equipped with a flow rate control valve 12, a sealing water storage part, and a heat exchanger 13. Extension of the deaeration unit is completed by installing a module bed having an extension unit placed thereon to the control unit 4 and connecting respective kinds of pipe lines. Thereby, the whole of the degasifier 1 becomes compact, the installing space is small, the aeration module can be easily extended, and deaeration efficiency can be improved by water seal cooling of the vacuum pump.

摘要： PROBLEM TO BE SOLVED: To sharply reduce a cost by arranging a flow rate variable element to adjust a flow rate by elastic deformation by fluid pressure at water feeding time and a cutoff member to cut off the opening part of the flow rate variable element by back pressure at water feed stopping time. SOLUTION: The opening part 4 of a flow rate variable element 3 is deformed in a funnel shape on the basis of fluid pressure of raw water flowing in from the primary side to adjust a flow rate of the raw water. The raw water flows outside through an outflow passage 8 and a raw water outlet 13. The flow of the raw water is not hindered since the space part is generated between the opening part 4 and a valve element 5 after the valve element 5 moves to the secondary side by fluid pressure at raw water supply time from this primary side. The flow rate variable element 3 is restored by resiliency when supply of the raw water is stopped. The valve element 5 moves to the flow rate variable element 3 side since back pressure is applied to the inside of the umbrella-shaped part of the valve element 5 when the raw water flows backward from the secondary side, so that the umbrella-shaped part of the valve element 5 is brought into pressure contact with the opening part 4 to check a ounterflow of the raw water.
