產(chǎn)品結(jié)構(gòu)特點(diǎn) Construction features 內(nèi)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(zhì)向兩方向流動(dòng)的環(huán)網(wǎng)管路上，也就說介質(zhì)流向不受限制。全開時(shí)，密封面受工作介質(zhì)的沖 蝕比截止閥小。形體結(jié)構(gòu)比較簡單，制造工藝性較好，結(jié)構(gòu)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(shù)規(guī)范 Technical specification 閘閥結(jié)構(gòu)長度和外接尺寸 Main connection dimensions
