碳鋼截止閥 內螺紋截止閥 絲扣S型截止閥J11H16C
產品概述
碳鋼截止閥J11H-16C是一款采用內螺紋連接的通用閥門，專為控制流體通斷設計。其閥體材質為優質碳鋼（WCB），具有耐高溫、耐壓及耐腐蝕特性，適用于水、蒸汽、油品等介質的管路系統。該閥門采用S型流道結構，通過旋轉手輪驅動閥瓣垂直升降實現啟閉，密封面堆焊硬質合金，確保長期使用的密封可靠性。產品結構緊湊，安裝便捷，廣泛應用于石油、化工、電力、制藥等工業領域。124
結構特點
J11H-16C采用內螺紋（絲扣）連接方式，閥體與管道通過螺紋直接緊固，適用于DN15-DN50的小口徑管道。其S型流道設計降低了流體阻力，閥瓣與閥座密封面采用錐面接觸，啟閉過程中磨損小且密封性能穩定。閥桿經調質處理，抗擦傷性強；手輪操作輕便，啟閉行程短，可快速完成流體控制。此外，閥門整體發黑處理，無需額外噴漆即可防銹，適合高溫或腐蝕性環境。61219
性能優勢
該閥門在設計中兼顧實用性與經濟性。與閘閥相比，其結構更簡單，維修方便且密封面壽命長；流體單向流動設計（建議介質從閥瓣下方流入）進一步提升了密封效果。缺點是流體阻力略大，但通過優化流道可減少壓力損失。閥門適用于常壓至16MPa的工作環境，溫度范圍覆蓋-29℃至425℃，能滿足大多數工業場景需求。91115
應用場景
J11H-16C碳鋼截止閥適用于建筑給排水、暖通系統、工業設備管道等場景，尤其適合空間受限的安裝環境。在化工領域可用于弱腐蝕性介質控制，在電力系統中則能穩定處理高溫蒸汽。其內螺紋連接方式簡化了小型管道的安裝流程，而S型閥體結構便于在復雜管路布局中靈活部署。72227
Product Overview
The J11H-16C carbon steel globe valve is a threaded-end valve designed for fluid shut-off applications. Constructed from WCB carbon steel, it exhibits high-temperature resistance, pressure tolerance, and corrosion durability, making it suitable for water, steam, and oil pipelines. The S-shaped flow path minimizes turbulence, while the handwheel-operated stem ensures precise vertical movement of the disc. Hard-faced sealing surfaces enhance longevity, and compact dimensions allow easy integration into industrial systems such as petrochemical plants, power stations, and pharmaceutical facilities. 1414
Design Features
Featuring NPT/BSP threaded connections (DN15-DN50), this valve adopts a conical disc-to-seat contact for leak-tight closure. The forged body undergoes black oxide treatment for rust prevention, and the tempered stem resists wear. Its short-stroke operation reduces manual effort, and the low-profile design suits confined spaces. The unidirectional flow design (recommended inlet under disc) optimizes sealing under pressure. 61218
Performance Highlights
Balancing efficiency and cost-effectiveness, the J11H-16C outperforms gate valves in simplicity and maintenance. Though slightly higher flow resistance exists, the streamlined S-path mitigates pressure drop. It handles pressures up to 16MPa and temperatures from -29°C to 425°C, ensuring versatility across utilities, HVAC, and light corrosive media. The threaded ends eliminate flange complexity, ideal for retrofit projects. 91526
Typical Applications
Ideal for compact piping in buildings, industrial machinery, and process lines, this valve excels in steam distribution, water treatment, and chemical dosing systems. Its threaded ends simplify small-pipe installations, while the robust carbon steel construction supports long-term use in demanding environments like thermal power plants or chemical processing units. 72225
