進(jìn)口重錘式液控止回蝶閥應(yīng)用于水泵出口時(shí)，與水泵實(shí)現(xiàn)泵閥聯(lián)動(dòng)，方便實(shí)現(xiàn)先啟泵后開(kāi)閥；在停泵或水泵事故跳閘時(shí)能實(shí)現(xiàn)兩級(jí)關(guān)閉，對(duì)停泵過(guò)程中產(chǎn)生的升壓造成的水錘危害，水泵機(jī)組倒轉(zhuǎn)等有顯著的消除和抑制作用，是保證水泵機(jī)組和管網(wǎng)系統(tǒng)安全可靠運(yùn)行的有效設(shè)備。

When the imported heavy hammer hydraulic control check butterfly valve is applied at the outlet of the water pump, it realizes 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.

性能參數(shù) performance parameter

原理

1.靠重錘勢(shì)能可自動(dòng)關(guān)閥  Close the valve automatically by heavy hammer potential energy

2.密封可靠、流阻系數(shù)小  Reliable seal and small resistance coefficient.?

3.采用PLC智能控制系統(tǒng)，可實(shí)現(xiàn)文本、觸摸屏等多種人性化操作界面 The PLC intelligent control system can realize various humanized operation interfaces such as text and touch screen

4.可以實(shí)現(xiàn)遠(yuǎn)程、本地控制 Remote and local control can be achieved.?

5.能按預(yù)定程序?qū)崿F(xiàn)與其他管路設(shè)備聯(lián)動(dòng)操作 It can realize the linkage operation with other pipeline equipment according to the predetermined procedure

6.具有快、慢可調(diào)的關(guān)閉功能 6. Has a fast and slow and adjustable shutdown function

7.具有截止、止回功能 With cut-off and check functions.

?8.關(guān)閉時(shí)能實(shí)現(xiàn)緩閉功能，有效消除水錘危害，保護(hù)水輪機(jī)、?水泵及管網(wǎng)系統(tǒng)的安全When closing, it can realize the slowing and closing function, effectively eliminate the harm of the water hammer, and protect the water turbine?Safety of the water pump and pipe network system.

液壓系統(tǒng)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(kāi)閥、失電蝶閥關(guān)閥為反作用型，即電磁閥失電蝶閥開(kāi)閥、得電蝶閥關(guān)閥、常規(guī)配套電磁換向閥為正作用型，?采用反作用型應(yīng)在訂貨時(shí)說(shuō)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.

主要構(gòu)件材料 Main component materials

臥式布置時(shí)，傳動(dòng)機(jī)構(gòu)--般采用正向安裝；受現(xiàn)場(chǎng)空間限制時(shí)也可根據(jù)用戶(hù)要求采用反裝型（即傳動(dòng)裝置位于閥體的另---側(cè)，見(jiàn)圖1-圖2）

For horizontal arrangement, the transmission mechanism adopts forward installation; and the reverse installation type can also be used according to the user requirements (i. e., the transmission device is located on the other- - -side of the valve body, see Figure 1-Figure 2)
