進(jìn)口緩閉式止回閥德國(guó)洛克 

一、進(jìn)口緩閉式止回閥描述：

德國(guó)LOCKE洛克進(jìn)口緩閉式止回閥是安裝在高層建筑給水系統(tǒng)以及其他給水系統(tǒng)的水泵出口處、防止介質(zhì)倒流、水錘及水擊現(xiàn)象的智能型閥門。該閥兼具電動(dòng)閥、逆止閥和水錘消除器三種功能，可有效地提高供水系統(tǒng)的安全可靠性、并將緩開、速閉、緩閉消除水錘的技術(shù)原理一體化，防止開泵水錘和停泵水錘的產(chǎn)生。只需操作水泵電機(jī)啟閉按鈕，閥門即可按照水泵操作規(guī)程自動(dòng)實(shí)現(xiàn)啟閉，流量大、壓力損失小。 

The slow closing check valve imported from Locke lock, Germany, is an intelligent valve installed at the water pump outlet of the water supply system of high-rise buildings and other water supply systems to prevent medium backflow, water hammer and water hammer. The valve has three functions of electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the water supply system, and integrate the technical principles of slow opening, quick closing and slow closing to eliminate water hammer, so as to prevent the occurrence of water hammer of opening pump and stopping pump. Just operate the water pump motor on / off button, the valve can automatically realize on / off according to the water pump operation regulations, with large flow and small pressure loss.

二、進(jìn)口緩閉式止回閥技術(shù)特點(diǎn)：

1、閥體采用全通道、流線型設(shè)計(jì)，流體阻力小、流量大；

2、閥體、閥蓋內(nèi)外采用環(huán)氧樹脂粉體涂裝，可防止閥體、閥蓋的腐蝕；

3、采用可拆卸閥座的先進(jìn)技術(shù)，結(jié)構(gòu)巧妙，維修更換方便（無須整臺(tái)閥門拆除）；

4、在管路中可任意立式或臥式安裝，其可靠性不變；

5、閥體、閥蓋、活塞缸連接處采用密封墊或密封環(huán)雙重保護(hù)；

6、活塞缸采用導(dǎo)流孔，適當(dāng)增加阻力，使活塞運(yùn)動(dòng)更加平穩(wěn)、靈活；

7、全不銹鋼活塞缸、整體活塞、丁晴橡膠密封環(huán)，完全組合大大延長(zhǎng)使用壽命。

1. The valve body adopts full channel and streamline design, with small fluid resistance and large flow;

2. The inside and outside of the valve body and valve cover are coated with epoxy resin powder to prevent the corrosion of the valve body and valve cover;

3. Adopting the advanced technology of detachable valve seat, the structure is ingenious, and the maintenance and replacement are convenient (the whole valve is not needed to be dismantled);

4. It can be installed in any vertical or horizontal way in the pipeline, and its reliability remains unchanged;

5. The joint of valve body, valve cover and piston cylinder is protected by sealing gasket or ring;

6. The piston cylinder adopts a guide hole to increase the resistance properly, so that the piston movement is more stable and flexible;

7. All stainless steel piston cylinder, integral piston, NBR seal ring, complete combination greatly extend the service life.
