碳鋼截止閥 內(nèi)螺紋截止閥 絲扣S型截止閥J11H16C
產(chǎn)品概述
碳鋼截止閥J11H-16C是一款采用內(nèi)螺紋連接的通用閥門(mén)，專(zhuān)為控制流體通斷設(shè)計(jì)。其閥體材質(zhì)為優(yōu)質(zhì)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(zhì)的管路系統(tǒng)。該閥門(mén)采用S型流道結(jié)構(gòu)，通過(guò)旋轉(zhuǎn)手輪驅(qū)動(dòng)閥瓣垂直升降實(shí)現(xiàn)啟閉，密封面堆焊硬質(zhì)合金，確保長(zhǎng)期使用的密封可靠性。產(chǎn)品結(jié)構(gòu)緊湊，安裝便捷，廣泛應(yīng)用于石油、化工、電力、制藥等工業(yè)領(lǐng)域。124
結(jié)構(gòu)特點(diǎn)
J11H-16C采用內(nèi)螺紋（絲扣）連接方式，閥體與管道通過(guò)螺紋直接緊固，適用于DN15-DN50的小口徑管道。其S型流道設(shè)計(jì)降低了流體阻力，閥瓣與閥座密封面采用錐面接觸，啟閉過(guò)程中磨損小且密封性能穩(wěn)定。閥桿經(jīng)調(diào)質(zhì)處理，抗擦傷性強(qiáng)；手輪操作輕便，啟閉行程短，可快速完成流體控制。此外，閥門(mén)整體發(fā)黑處理，無(wú)需額外噴漆即可防銹，適合高溫或腐蝕性環(huán)境。61219
性能優(yōu)勢(shì)
該閥門(mén)在設(shè)計(jì)中兼顧實(shí)用性與經(jīng)濟(jì)性。與閘閥相比，其結(jié)構(gòu)更簡(jiǎn)單，維修方便且密封面壽命長(zhǎng)；流體單向流動(dòng)設(shè)計(jì)（建議介質(zhì)從閥瓣下方流入）進(jìn)一步提升了密封效果。缺點(diǎn)是流體阻力略大，但通過(guò)優(yōu)化流道可減少壓力損失。閥門(mén)適用于常壓至16MPa的工作環(huán)境，溫度范圍覆蓋-29℃至425℃，能滿(mǎn)足大多數(shù)工業(yè)場(chǎng)景需求。91115
應(yīng)用場(chǎng)景
J11H-16C碳鋼截止閥適用于建筑給排水、暖通系統(tǒng)、工業(yè)設(shè)備管道等場(chǎng)景，尤其適合空間受限的安裝環(huán)境。在化工領(lǐng)域可用于弱腐蝕性介質(zhì)控制，在電力系統(tǒng)中則能穩(wěn)定處理高溫蒸汽。其內(nèi)螺紋連接方式簡(jiǎn)化了小型管道的安裝流程，而S型閥體結(jié)構(gòu)便于在復(fù)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
