焊接針型閥J61W/Y160P高溫高壓對焊針型閥 電站專用針型截止閥
產(chǎn)品概述
焊接針型閥J61W/Y-160P是一種專為高溫高壓工況設(shè)計的高性能閥門，廣泛應(yīng)用于電站、石油化工、電力系統(tǒng)等領(lǐng)域的管道控制。該閥門采用對焊連接方式，確保與管道系統(tǒng)的緊密集成，具有優(yōu)異的密封性能和耐壓能力。其閥芯采用錐形設(shè)計，能夠精確控制小流量介質(zhì)，適用于蒸汽、油品、水及弱腐蝕性化學(xué)介質(zhì)的啟閉與調(diào)節(jié)。閥體材質(zhì)可選碳鋼、不銹鋼（304/316/316L）或耐熱合金鋼，滿足不同介質(zhì)和溫度環(huán)境的需求。工作溫度范圍覆蓋-29℃至570℃，壓力等級可達(dá)32MPa，適用于極端工況。169
結(jié)構(gòu)特點
該閥門采用上螺紋閥桿結(jié)構(gòu)，避免介質(zhì)與螺紋直接接觸，延長使用壽命。密封面采用硬質(zhì)合金堆焊或紫銅/四氟材料，確保高溫高壓下的可靠密封。閥體設(shè)計帶散熱片（部分型號），有效降低高溫對操作部件的影響。連接方式為對焊或承插焊，安裝便捷且無泄漏風(fēng)險。此外，閥門支持手輪、條鋼等多種操作方式，顏色可選紅、藍(lán)、黑等，便于現(xiàn)場識別。3511
應(yīng)用場景
J61W/Y-160P主要用于火力發(fā)電廠的蒸汽管路、儀表測量系統(tǒng)及熱循環(huán)水管道，作為截止或流量調(diào)節(jié)裝置。其緊湊的設(shè)計和高壓耐受性使其成為電站一次門、壓力表配套閥門的理想選擇。同時，該閥門也適用于化工裝置的腐蝕性介質(zhì)控制，以及石油行業(yè)的油品輸送系統(tǒng)。安裝時需注意介質(zhì)流向與閥體箭頭標(biāo)識一致，焊接需牢固以確保長期穩(wěn)定運(yùn)行。2821
Product Overview
The J61W/Y-160P welded needle valve is a high-performance valve designed for high-temperature and high-pressure applications, widely used in power plants, petrochemical industries, and pipeline systems. Featuring a butt-welded connection, it ensures seamless integration with pipelines while delivering exceptional sealing and pressure resistance. The tapered valve core enables precise flow control for small-volume media such as steam, oil, water, and mildly corrosive chemicals. The valve body is available in carbon steel, stainless steel (304/316/316L), or heat-resistant alloys, catering to diverse operational environments with a temperature range of -29°C to 570°C and pressure ratings up to 32MPa. 6915
Design Features
This valve incorporates an upper-threaded stem structure to prevent direct media contact, enhancing durability. Sealing surfaces utilize hard alloy overlays, copper, or PTFE materials for reliability under extreme conditions. Some models include heat-dissipating fins to mitigate thermal effects. The butt-weld or socket-weld connections facilitate easy installation with zero leakage risks. Manual operation options include handwheels or lever handles, available in multiple colors for identification. 31119
Applications
Primarily deployed in steam pipelines, instrumentation systems, and thermal water circuits of thermal power plants, the J61W/Y-160P serves as a shut-off or flow-regulation device. Its compact design and high-pressure tolerance make it ideal for primary isolation valves and pressure gauge installations. It also suits corrosive media control in chemical plants and oil transportation systems. Installation requires aligning the medium flow direction with the valve’s arrow marking and ensuring robust welding for long-term stability. 2823
