用途 use to

進口蓄能器式液控止回蝶閥應用于水泵出口時，與水泵實現泵閥聯動，方便實現先啟泵后開閥；在停泵或水泵事故跳閘時能實現兩級關閉，對停泵過程中產生的升壓造成的水錘危害，水泵機組倒轉等有顯著的消除和抑制作用，是保證水泵機組和管網系統安全可靠運行的有效設備。

When the imported accumulator type hydraulic control check butterfly valve is applied at the outlet of the water pump, it achieves pump valve linkage with the water pump, making it convenient to start the pump first and then open the valve; The two-stage shutdown can be achieved in the event of pump shutdown or pump accident tripping, which significantly eliminates and suppresses the water hammer hazards caused by pressure rise during pump shutdown and the reverse rotation of the pump unit. It is an effective equipment to ensure the safe and reliable operation of the pump unit and pipeline system.

主要構件材料 Main component materials

液壓系統電磁換向閥控制特征一般為正作用型The control characteristics of the electromagnetic reversing valve of the hydraulic system are generally the positive action type.

即：電磁閥得電蝶閥開閥、失電蝶閥關閥為反作用型，即電磁閥失電蝶閥開閥、得電蝶閥關閥、常規配套電磁換向閥為正作用型，?采用反作用型應在訂貨時說明。

Namely: the solenoid valve got electric butterfly valve open valve, electric butterfly valve closing valve is counterproductive type, that is, the solenoid valve lost electric butterfly valve open valve, electric butterfly valve closing valve, conventional supporting electromagnetic change valve is positive type,?The reaction type shall be indicated when ordering.

臥式布置時，傳動機構-般采用正向安裝；受現場空間限制時也可根據用戶要求采用反裝型（即傳動裝置位于閥體的另一側）

For horizontal arrangement, the transmission mechanism adopts forward installation, or according to the requirements of the user (namely, the transmission device is located on the other side of the valve body
