在工業(yè)自動化控制系統(tǒng)中，調(diào)節(jié)閥是執(zhí)行器的“王牌”——它不像閘閥那樣只負(fù)責(zé)“開”和“關(guān)”，而是根據(jù)控制信號實時調(diào)整閥門開度，合理控制介質(zhì)的流量、壓力、溫度和液位。良工閥門集團(tuán)的調(diào)節(jié)閥產(chǎn)品線覆蓋了從-200℃深冷到560℃超高溫的出彩端工況，是工業(yè)自動化領(lǐng)域不可或缺的“智能調(diào)節(jié)師”。

In the industrial automation control system, the regulating valve is the "ace" of the actuator - it is not only responsible for "opening" and "closing" like the gate valve, but also for adjusting the opening of the valve in real time according to the control signal to accurately control the flow, pressure, temperature and liquid level of the medium. The regulating valve product line of Lianggong Valve Group covers extreme working conditions from -200 ℃ deep cold to 560 ℃ ultra-high temperature, and is an indispensable "intelligent regulator" in the field of industrial automation.

一、調(diào)節(jié)閥的工作原理與核心價值

1、 The working principle and core value of regulating valves

調(diào)節(jié)閥的核心任務(wù)是“調(diào)節(jié)”——根據(jù)來自控制系統(tǒng)的4-20mA電流信號或0-10V電壓信號，改變閥芯與閥座之間的流通面積，從而實現(xiàn)對介質(zhì)流量的準(zhǔn)確控制。與普通開關(guān)閥不同，調(diào)節(jié)閥的閥芯可以在任意位置停留，實現(xiàn)從全關(guān)到全開的無級調(diào)節(jié)。

The core task of a regulating valve is "regulation" - based on the 4-20mA current signal or 0-10V voltage signal from the control system, it changes the flow area between the valve core and the valve seat, thereby achieving precise control of the medium flow rate. Unlike ordinary on-off valves, the valve core of the regulating valve can stay at any position, achieving stepless adjustment from fully closed to fully open.

良工調(diào)節(jié)閥的技術(shù)優(yōu)勢體現(xiàn)在高精度、高可靠性、強(qiáng)適應(yīng)性三個維度。以ZXP型新系列氣動薄膜直通單座調(diào)節(jié)閥為例，它采用頂導(dǎo)向結(jié)構(gòu)，配用多彈簧執(zhí)行機(jī)構(gòu)，具有結(jié)構(gòu)緊湊、重量輕、動作靈敏、流體通道呈S流線型、壓降損失小、閥容量大、流量特性準(zhǔn)確、拆裝方便等優(yōu)點。該系列產(chǎn)品公稱壓力等級有PN10、16、40、64；閥體口徑范圍DN20至200mm；適用流體溫度從-200℃到560℃范圍內(nèi)多種檔次；泄漏量標(biāo)準(zhǔn)可達(dá)IV級或VI級。

The technical advantages of Lianggong regulating valves are reflected in three dimensions: high precision, high reliability, and strong adaptability. Taking the ZXP new series pneumatic thin film straight through single seat regulating valve as an example, it adopts a top guide structure and is equipped with a multi spring actuator. It has the advantages of compact structure, light weight, sensitive action, S-shaped fluid channel, low pressure drop loss, large valve capacity, precise flow characteristics, and easy disassembly and assembly. The nominal pressure rating of this series of products includes PN10, 16, 40, and 64; Valve body diameter range DN20 to 200mm; suitable for fluid temperatures ranging from -200 ℃ to 560 ℃ in various grades; The leakage standard can reach level IV or level VI.

二、良工調(diào)節(jié)閥的主流產(chǎn)品系列

2、 The mainstream product series of Lianggong regulating valves

氣動薄膜調(diào)節(jié)閥是良工調(diào)節(jié)閥的“當(dāng)家花旦”。ZXP型氣動薄膜直通單座調(diào)節(jié)閥廣泛應(yīng)用于控制氣體、液體、蒸汽等介質(zhì)，非常適用于允許泄漏量小、閥前后壓差不大的工作場合。ZXN型氣動薄膜雙座調(diào)節(jié)閥采用雙導(dǎo)向結(jié)構(gòu)，非常適用于允許壓差較大的場合。

Pneumatic thin film regulating valve is the "leading actress" of Lianggong regulating valve. The ZXP type pneumatic thin film straight through single seat regulating valve is widely used to control media such as gas, liquid, steam, etc., especially suitable for working environments with small allowable leakage and small pressure difference before and after the valve. The ZXN pneumatic thin film double seat regulating valve adopts a dual guide structure, which is particularly suitable for situations where a large pressure difference is allowed.

電動調(diào)節(jié)閥則適用于需要遠(yuǎn)程自動化控制的場景。ZDLP電動單座調(diào)節(jié)閥由PSL系列和3810L系列電子式執(zhí)行機(jī)構(gòu)和單座調(diào)節(jié)閥組成，電源為220V.AC 50Hz，可直接接受工業(yè)控制儀表或計算機(jī)輸出的4-20mADC或1-5VDC信號進(jìn)行閥門的開度控制。該閥具有精度高、流量大、泄漏量小的特點，廣泛用于化工、石油、輕工、電站、冶金等要求流量大、泄漏量小的工業(yè)自控系統(tǒng)中。

Electric control valves are suitable for scenarios that require remote automation control. The ZDLP electric single seat regulating valve consists of PSL series and 3810L series electronic actuators and single seat regulating valves. The power supply is 220V, AC 50Hz, and can directly receive 4-20mADC or 1-5VDC signals output by industrial control instruments or computers for valve opening control. This valve has the characteristics of high precision, large flow rate, and small leakage, and is widely used in industrial automation systems such as chemical, petroleum, light industry, power plants, metallurgy, etc. that require large flow rate and small leakage rate.

電動套筒調(diào)節(jié)閥（ZAZME） 公稱通徑由20至200mm，公稱壓力有1.0、1.6、4.0、6.4MPa，使用溫度范圍由-40℃～450℃。其中電動單座調(diào)節(jié)閥適用于壓差較小、介質(zhì)粘度較大或稍有顆粒雜質(zhì)的場合；電動套筒調(diào)節(jié)閥適用于壓差較大的場合。

The nominal diameter of the electric sleeve regulating valve (ZAZME) ranges from 20 to 200mm, with nominal pressures of 1.0, 1.6, 4.0, and 6.4MPa. The operating temperature range is from -40 ℃ to 450 ℃. The electric single seat regulating valve is suitable for situations with small pressure difference, high medium viscosity, or slight particle impurities; Electric sleeve regulating valves are suitable for situations with large pressure differentials.

自力式調(diào)節(jié)閥（ZZYP） 無需外加能源，利用被調(diào)介質(zhì)自身能量為動力源，引入執(zhí)行機(jī)構(gòu)控制閥芯位置，改變兩端的壓差和流量，使閥前或閥后壓力穩(wěn)定，具有動作靈敏、密封性好、壓力設(shè)定點波動小等優(yōu)點。

The self regulating valve (ZZYP) does not require external energy and uses the energy of the regulated medium as a power source. It introduces an actuator to control the position of the valve core, changes the pressure difference and flow rate at both ends, and stabilizes the pressure before or after the valve. It has the advantages of sensitive action, good sealing performance, and small pressure set point fluctuations.

手動調(diào)節(jié)閥（T40H） 適用于工作壓力≤1.6MPa、介質(zhì)溫度≤200℃的蒸汽或熱水管路上調(diào)節(jié)流量。其調(diào)節(jié)性能優(yōu)于閘閥和截止閥，具有近似線性的調(diào)節(jié)性能，能有效改善供熱條件和水力工況。

The manual regulating valve (T40H) is suitable for regulating flow on steam or hot water pipelines with working pressure ≤ 1.6MPa and medium temperature ≤ 200 ℃. Its regulating performance is superior to gate valves and globe valves, with approximately linear regulating performance, which can effectively improve heating conditions and hydraulic conditions.
