                                                                                                                                                                                                             側裝磁翻板液位計底部一般常規會有一個排污閥,作用就是液位機里面液體排出作用。磁翻板液位計常用的排污閥有哪些:

                                                                                                                                                                                                             第一:絲堵用于管道的末端,防止管道的泄露,起到密封的作用,是水暖系統安裝中常用的管件,公稱壓力為1-1.6Mpa。

                                                                                                                                                                                                            第二:常溫常壓的情況下使單片球閥。

                                                                                                                                                                                                            第三:溫度稍微高一些例如150度以上,壓力在1.6MPA左右可以選用雙片球閥。

                                                                                                                                                                                                            第四:高溫(250度以上,壓力4MPa以上建議使用針閥。

                                                                                                                                                                                                            區別:

                                                                                                                                                                                                            單片式球閥和雙片式球閥的工作原理不同:一片式球閥工作原理是閥桿的機械施壓作用; 兩片式球閥的工作原理是靠旋轉閥戀來使閥門暢通或閉塞。

                                                                                                                                                                                                            針閥:針閥是一種微調閥,其閥塞為針形,主要用作調節氣流量。微調閥要求閥口開啟逐漸變大,從關閉到開啟最大能連續細微地調節。針形閥塞即能實現這種功能。針形閥塞一般用經過淬火的鋼制長針,而閥座是用錫、銅等軟質材料制成。閥針與閥座間的密封是依靠其錐面緊密配合達到的。閥針的錐度有1:50和60錐角兩種,錐表面要經過精細研磨。閥桿與閥座間的密封是靠波紋管實現的。
                                                                                                                                                                                                            以上就是側裝磁翻板液位計常用的閥門,如需進一步咨詢或者了解,您可以撥打相遠服務熱線:400-101-2883.
