燃气调压柜（箱）Gas regulating cabinet
把调压、切断、放散、计量装进一个箱体，落地即用，适合场地紧张的门站末端、厂区与小区。Regulation, slam-shut, relief and metering inside one cabinet for tight sites.
产品概述Product overview
调压柜是撬的“紧凑版”：不设独立基础平台，箱体本身做防护，占地只有撬的三分之一左右。800 Nm³/h 柜的进口压力 0.9–0.99 MPa、出口 20–25 kPa，一级调压即可满足；400 Nm³/h 单路柜（HBTR-NG/400）多用于厂区与商业用户；880 Nm³/h 调压箱用于小区与公建。A cabinet is the compact form: 800 Nm³/h at 0.9–0.99 MPa inlet and 20–25 kPa outlet in a single stage; 400 and 880 Nm³/h units serve plants and residential areas.
2026 年这类产品拿到了 EAC 认证，可以进入俄语区市场——对出口项目来说，这是能否投标的前置条件，而不只是加分项。EAC certification obtained in 2026 opens Russian-speaking markets — a bid prerequisite, not a bonus.
工作原理：把一座小站装进箱体Working principle: a small station inside a box
调压柜是“站”的浓缩版：调压器、过滤器、安全切断阀、放散阀、计量与仪表全部装进一个可运输的箱体，现场只需基础与进出口接管。省掉的是土建与站房，不是功能。A regulating cabinet is a station in miniature: regulator, filter, slam-shut valve, relief, metering and instruments inside a transportable enclosure. What is saved is civil works and a building — not function.
箱体本身也是安全设备。它要保证通风（泄漏气体不能积聚）、防雨防尘、防爆（电气与照明按区域选型）、以及放散口的安全朝向。很多现场问题不是调压器不好，而是柜内通风不足、放散管朝向不对、或检修空间被塞满。The enclosure is safety equipment in its own right: it must ventilate so leaked gas cannot accumulate, keep rain and dust out, use Ex-rated electrics and lighting, and aim the vent safely. Many site problems trace to poor ventilation, a wrongly aimed vent, or no room left to service anything.
与独立调压站相比，柜的优势是占地小、工期短、可整体迁移；劣势是散热与检修空间受限，大流量、高压差的场合仍建议做站。选型判断标准是流量与压差，而不是“柜子便宜”。Against a built station, the cabinet wins on footprint, schedule and relocatability; it loses on heat dissipation and service room. For large flow or large ratios a station is still the right answer. The deciding variables are flow and ratio, not price.

常见问题FAQ
柜子能放在室内吗？Can the cabinet sit indoors?
可以，但要满足通风、泄爆与防火分隔要求，且不能放在人员密集或封闭无通风的房间。多数项目放在室外或有独立通风的房间。Yes, with ventilation, explosion relief and fire separation, and never in an occupied or unventilated room. Most projects place it outdoors or in a separately ventilated room.
放散管要多高？How tall should the vent be?
按规范与现场条件确定，原则是排放物不能进入人员活动区、不能靠近进气口与火源。设计阶段就要定，不要现场临时加高。Per code and site conditions: discharge must not reach occupied areas or sit near air intakes and ignition sources. Fix it at design stage, not on site.
冬天取压管结冰怎么解决？How is an iced sensing line solved?
加电伴热并保温，或把取压点移到温度更稳定的位置；也可在取压管加隔离罐。结冰会让调压器读错压力，出口压力异常升高。Trace and insulate, relocate the tap to a warmer point, or add a isolating pot. Ice makes the regulator read a false pressure and drives the outlet high.
柜内可以加计量吗？Can metering be added inside?
可以，一体化调压计量柜很常见。但要为计量段留出直管段与校验接口，并考虑换表时的吊装空间。Yes — integrated cabinets are common — but reserve straight lengths and a calibration port, and allow room to lift a meter out.
柜体需要接地吗？Does the cabinet need earthing?
需要。柜体、管道与电气设备都要可靠接地，防雷与防静电按规范做，接地电阻要实测记录。Yes. Enclosure, pipework and electrics all need reliable earthing, with lightning and static protection to code and measured resistance recorded.
