Grease Injector at Seat Ring and Disc of Globe Valve. 截止閥的閥座環(huán)和閥瓣上的潤滑油注入器。
Globe valves are usually installed with the inlet below the valve seat. 安裝截止閥時(shí)，通常把進(jìn)口安裝在閥座下方。
Where an air distribution valve manifold is used and its air sub-header shutoff valve is not accessible from the manifold, a shutoff valve at the manifold shall be provided. 如果使用了空氣分布閥門(mén)集管，其空氣分支總管切斷閥不應通過(guò)此集管，而應為集管安裝切斷閥。
Each instrument requiring an air supply shall be supplied with an individual combination air filter and relief type reducing regulator and an adjacent individual shutoff valve. 要求使用儀表風(fēng)的每個(gè)儀表應配備單獨的混合空氣過(guò)濾器和泄壓型調壓閥及相鄰的單獨切斷閥。
