Hydraulic slowly-closing pneumatic ball valve control characteristics and USES

hydraulic controlled pneumatic valve is introduced:
hydraulic controlled pneumatic valve is more advanced pipeline control equipment at home and abroad, mainly installed on the hydraulic turbine, used as a water turbine imported pneumatic valve; Or installed in water conservancy, electric power, water supply and drainage and other kinds of pumping station pumps export, alternative to check the function of the pneumatic valve and gate valve. Work, pneumatic valve and pipeline host to cooperate, in accordance with the principle of the transient process of water through the preset opening and closing procedures, effectively eliminate the pipeline water hammer, realize reliable cutoff of piping, play a role to protect the safety of pipeline system.
hydraulic slowly-closing pneumatic ball valve USES:
hydraulic slowly-closing pneumatic ball valve and flow resistance coefficient, high automatic degree, complete function, stable and reliable performance, etc have been used in all walks of life. Mainly in the following aspects:
, can replace the water pump outlet original electric brake the function of the pneumatic valve, pneumatic valve and check and put the machine, electricity, liquid systems integration as a whole, reduce the area and infrastructure investment.
, electro-hydraulic control function is all ready, no additional configuration can be used as an independent system of single machine on-site debugging and control; Can also be used as a distributed control system ( DCS） An equipment units, by the central computer through the I/O channels for centralized management, and water pumps, water turbine, the ventilation valve and other pipeline equipment to realize linkage operation; When there is no power supply and equipped with manual function, also can realize manual pneumatic valve open and close and meet the special working conditions of debugging, pneumatic valve control requirements.
good, controllable, the adjusting range is big, strong adaptability. Electro-hydraulic control system is equipped with several control points, can be in accordance with the requirements of different pipeline control for opening and closing application Settings, ensure to meet pneumatic valve open and close condition, pneumatic valve can automatically according to the preset time, the Angle open and fast, slow close two stages. And can realize electric pneumatic valve, effectively eliminate the destructive water hammer, to prevent the pump and turbine units runaway accident, reduce the pressure fluctuation of pipeline system, ensure safe and reliable operation of the equipment.
and main pneumatic valve sealing surface for triple eccentric metal seal or double eccentric rubber sealing structure, easy opening and closing, reliable sealing; And there is a additional increase of eccentricity, to close the pneumatic valve has good self, self sealing performance. Bat designed to streamline the medium and small size flat structure, drift diameter bat designed double plate girder structure, the crowd out small, smooth flow, pneumatic valve, flow resistance coefficient is only. ~。 , is far less than the check of the pneumatic valve flow resistance coefficient ( 。 ~。 ） , energy saving effect is obvious.
