                                                                                                                                船用閥門品種規格多,這是它的特點,同時又是阻礙閥門技術提高的問題所在。

                                                                                                                                龐大的品種、規格,對于閥門標準的編制、修訂,圖紙的繪制,組織的專業化生產、閥門的質量控制等都帶來一系列的困難。

                                                                                                                                船用閥門標準
