進口鍛鋼閘閥工作原理:

鍛鋼閘閥適用于適用于水、蒸汽、油品、硝酸、醋酸、氧化性介質、尿素以及石油管道上。鍛鋼閘閥采用縮徑設計，與同口徑的鑄鋼閘閥相比流量要稍小，但承受的壓力與溫度范圍要比鑄鋼閥門要高，密封性能也要比鑄鋼閘閥要好許多，壽命更長，介質流動方向同其他閘閥一樣不受限制。

Working principle of imported forged steel gate valve:
Forged steel gate valve is suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and oil pipeline. The forged steel gate valve adopts the reduced diameter design. Compared with the cast steel gate valve with the same diameter, the flow rate is slightly smaller, but the pressure and temperature range are higher than those of the cast steel gate valve. The sealing performance is much better than that of the cast steel gate valve, and the service life is longer. The medium flow direction is not limited as other gate valves.

進口鍛鋼閘閥產品簡介:

德國洛克《DE LOCKE》進口鍛鋼閘閥有三種閥蓋設計形式。*種是螺栓式閥蓋，按這種設計形式設計的閥門，其閥體與閥蓋用螺栓螺母連接，纏繞式墊片(316夾柔性石墨制造)密封，客戶有特殊要求時也可采用金屬環連接；*種設計形式是焊接式閥蓋，按這種設計形式的閥門，其閥體與閥蓋用螺紋連接，全焊密封，客戶有特殊要求時也可采用全焊逶連接；第三種是壓力自緊式閥蓋，按這種設計形式設計的閥門，其閥體與閥蓋用螺紋連接，內壓自密封環密封。

Brief introduction of imported forged steel gate valve products:
There are three kinds of bonnet design forms for the imported forged steel gate valve of German Locke de Locke. The first type is bolted bonnet. The valve body and bonnet are connected by bolts and nuts, and sealed by spiral wound gasket (made of 316 clip flexible graphite). When customers have special requirements, metal ring connection can be used. The second type is welded bonnet. The valve body and bonnet are connected by thread and sealed by full welding When there are special requirements, full welded connection can also be used; the third type is pressure self tightening bonnet. For the valve designed according to this design, the valve body and bonnet are connected by thread, and the internal pressure self sealing ring is used for sealing.
