進(jìn)口靜音止回閥質(zhì)量就是好德國(guó)洛克《DE LOCKE》

 一、進(jìn)口靜音止回閥描述：

德國(guó)LOCKE洛克進(jìn)口靜音止回閥由閥體、閥座、導(dǎo)流體、閥瓣、軸瓦及彈簧等零件組成。內(nèi)部流道采用流線型設(shè)計(jì)，壓力損失小，閥瓣啟閉行程很短，停泵時(shí)可快速關(guān)閉，防止巨大的水錘聲，形成靜音效果。該閥主要用于給水、排水、消防、暖通系統(tǒng)，可安裝于水泵出口處，防止介質(zhì)倒流及水錘對(duì)泵的損壞。

German lock lock imported silent check valve is composed of valve body, valve seat, guide body, valve disc, bearing bush and spring and other parts. The internal flow passage adopts streamlined design, with small pressure loss and short opening and closing stroke of valve disc. When the pump is stopped, it can be closed quickly to prevent huge water hammer sound and form a silent effect. The valve is mainly used in water supply, drainage, fire fighting, heating and ventilation systems, which can be installed at the outlet of the water pump to prevent medium backflow and water hammer damage to the pump.
