進(jìn)口高壓?jiǎn)蜗蜷y產(chǎn)品概述：

德國(guó)《DE LOCKE》洛克-進(jìn)口高壓?jiǎn)蜗蜷y是指采用不銹鋼或者碳鋼材質(zhì)，采用整體鍛造，彈簧作用，耐高壓的單向閥，靠管路中介質(zhì)本身的流動(dòng)產(chǎn)生的力而自動(dòng)開啟和關(guān)閉的，屬于一種自動(dòng)閥門。單向閥用于管路系統(tǒng)，其主要作用是防止介質(zhì)倒流、防止泵及其驅(qū)動(dòng)電機(jī)機(jī)反轉(zhuǎn)，以及容器內(nèi)介質(zhì)的泄放。焊接式單向閥只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止方向流動(dòng)。

進(jìn)口高壓?jiǎn)蜗蜷y安裝要點(diǎn)：

1、單向閥安裝位置、高度、進(jìn)出口方向必須符合設(shè)計(jì)要求，注意介質(zhì)流動(dòng)的方向應(yīng)與閥體所標(biāo)箭頭方向一致，連接應(yīng)牢固緊密。

2、閥門安裝前必須進(jìn)行外觀檢查，，安裝前應(yīng)進(jìn)行強(qiáng)度和嚴(yán)密性能試驗(yàn)，合格后方準(zhǔn)使用。強(qiáng)度試驗(yàn)時(shí)試驗(yàn)壓力為公稱壓力的1.5倍，持續(xù)時(shí)間不少于5min，閥門殼體、填料應(yīng)無(wú)滲漏為合格。嚴(yán)密性試驗(yàn)時(shí)，試驗(yàn)壓力為公稱壓力的1.1倍；

3、在管線中不要使單向閥承受重量，大型的單向閥(ae t v  One-way valve)：應(yīng)du立支撐，使之不受管系產(chǎn)生的壓力的影響。

Installation points of imported high pressure check valve:
1. The installation position, height, inlet and outlet direction of one-way valve must meet the design requirements. The direction of medium flow shall be consistent with the arrow direction marked on the valve body, and the connection shall be firm and tight.
2. The appearance inspection must be carried out before the valve is installed, and the strength and tightness test shall be carried out before the valve is installed, and the valve can only be used after it is qualified. During the strength test, the test pressure shall be 1.5 times of the nominal pressure, and the duration shall not be less than 5min. The valve shell and packing shall be qualified if there is no leakage. In the tightness test, the test pressure is 1.1 times of the nominal pressure;
3. Don't make the check valve bear the weight in the pipeline. Large one-way valve should be supported vertically so that it is not affected by the pressure generated by the piping system.
