Belimo搏力謀電動球閥蝶閥:
Belimo搏力謀已成為暖通空調(diào)領(lǐng)域的者，產(chǎn)品包括belimo風(fēng)門執(zhí)行器、風(fēng)閥執(zhí)行器、belimo電動蝶閥、belimo電動調(diào)節(jié)閥、belimo電動球閥、belimo電動兩通閥。
belimo搏力謀控制球閥的技術(shù)：特殊的流量配置裝置—配流盤
搏力謀belimo解決球閥的控制穩(wěn)定性問題。搏力謀控制球閥在的特殊裝置---配流盤。配流盤是一側(cè)為凹型的球面，與球型閥芯表面良好配合。流量通過球型閥芯的配流盤V型開口之間的開度得到精密控制。因而將球閥C值減小到相同規(guī)格座閥的C值。配流盤確定了閥門的特性。備有不同形狀開口的配流盤，因而每種規(guī)格的閥門可以有不同的C值。
作為一家始創(chuàng)于1975年6月1日的瑞士公司，Belimo已經(jīng)從一家小型公司成長為現(xiàn)在的上市公司,不僅在世界各地設(shè)立了分公司及辦公網(wǎng)點(diǎn)，并成為了暖通空調(diào)領(lǐng)域的者。在過去的30年里，Belimo的品牌，產(chǎn)品得到了眾多客戶及終端用戶的一致認(rèn)可；Belimo象征著的產(chǎn)品，快速的供貨和永無止境的創(chuàng)新。為了繼續(xù)加大Belimo的成功步伐，Belimo亞太將全力以赴的為廣大客戶提供應(yīng)用在加熱，通風(fēng)及空調(diào)等領(lǐng)域的*品質(zhì)的風(fēng)門和控制閥。
