寶德burkert0280/一級代理寶德隔膜閥0280帶有伺服隔膜和強(qiáng)制提升裝置的先導(dǎo)式直通閥有兩種類型,即在無流量時(shí)關(guān)閉或在無流量時(shí)打開。當(dāng)作用方式 A 為關(guān)閉狀態(tài)時(shí),芯體會在彈簧力的作用下將先導(dǎo)式孔眼關(guān)閉。經(jīng)由一個(gè)隔膜節(jié)流孔,在隔膜上方形成介質(zhì)壓力,進(jìn)而關(guān)閉閥門。接通時(shí),芯體先打開先導(dǎo)式孔眼。隔膜上方的關(guān)閉壓力被卸除,且閥門由介質(zhì)壓力打開。為了*打開閥門,所需的差壓不能低于 0.5 bar
寶德burkert0280/一級代理There are two types of pilot direct valves with servo diaphragm and mandatory lifting device, which is to shut or open when there is no flow. When the action mode A is closed, the core will close the pilot hole with the force of spring. Through a diaphragm throttling hole, a medium pressure is formed over the diaphragm to close the valve. When connected, the core opens the pilot perforation. The closing pressure above the diaphragm is removed and the valve is opened by medium pressure. To fully open the valve, the required differential pressure must not be lower than 0.5 bar
