產品結構特點 Construction features 內螺紋與承插焊鍛鋼閘閥流體阻力小，啟、閉所需力矩較小，可以使用在介質向兩方向流動的環網管路上，也就說介質流向不受限制。全開時，密封面受工作介質的沖 蝕比截止閥小。形體結構比較簡單，制造工藝性較好，結構長度比較短。 The internal thread and the welded steel gate valve are small in the fluid resistance, and the torque is small, and can be used in the two directions of the loop network tube, which also means that the flow of the medium is not restricted. When open, the sealing cover is less than the closing valve of the working medium. The form structure is relatively simple, the manufacturing process is better, the structure length is shorter. 技術規范 Technical specification 閘閥結構長度和外接尺寸 Main connection dimensions
