進口鑄鋼絲扣閘閥
德國巴赫進口鑄鋼絲扣閘閥概述：
進口鑄鋼絲扣閘閥屬于強制密封式閥門，所以在閥門關閉時，必須向閥瓣施加壓力，以強制密封面不泄漏。當介質(zhì)由閥瓣下方進入閥體時，操作力所需要克服的阻力，是閥桿和填料的磨擦力與由介質(zhì)的壓力所產(chǎn)生的推力，關閥門的力比開閥門的力大，所以閥桿的直徑要大，否則會發(fā)生閥桿頂彎的故障。
Imported steel wire buckle gate valve
Germany Bach imported steel wire buckle gate valve overview:
Imports of cast steel gate valve is a mandatory seal valve, so the valve is closed, the valve must be applied to force the sealing surface does not leak. When the medium into the valve body from the bottom of the valve, the operating force required to overcome the resistance, is the stem and the packing friction and pressure generated by the media thrust force than the valve off the valve opening force, so the diameter of the valve stem, otherwise it will bend the stem top of the fault.
進口鑄鋼絲扣閘閥的定義：
1.結(jié)構(gòu)簡單，制造和維修比較方便。
2.工作行程小，啟閉時間短。
3.密封性好，密封面間磨擦力小，壽命較長。
Definition of imported steel wire buckle gate valve:
1 simple structure, easy to manufacture and maintenance.
2 working stroke is small, open and close time is short.
3 good sealing, sealing surface friction between small, long life.
