XSTOU 25P導(dǎo)閥型蒸汽減壓閥為導(dǎo)閥型隔膜式，有法蘭和螺紋連接，聯(lián)系在線客戶(hù)可提供樣本；斯派莎克25系列導(dǎo)閥型隔膜式調(diào)節(jié)閥，通過(guò)對(duì)同一主閥、不同型號(hào)導(dǎo)閥的多元化組合，可控制蒸汽壓力。XSTOU 25P導(dǎo)閥型蒸汽減壓閥在普通減壓閥的基礎(chǔ)上做了很大的改進(jìn)。膜片采用了新型材料，并大大加工了工作面積，因此閥門(mén)上游壓力或下游負(fù)荷細(xì)微的變化都能及時(shí)準(zhǔn)確的反饋到主閥膜片，來(lái)調(diào)節(jié)主閥的開(kāi)度，確保下游壓力的穩(wěn)定。
The XSTOU 25P pilot valve steam pressure reducing valve is a pilot valve diaphragm type, with flange and threaded connections. Contact online customers to provide samples; The Spark 25 series pilot valve diaphragm type regulating valve can control steam pressure through diversified combinations of the same main valve and different types of pilot valves. The XSTOU 25P pilot valve steam pressure reducing valve has made significant improvements on the basis of ordinary pressure reducing valves. The diaphragm adopts new materials and greatly processes the working area, so subtle changes in upstream pressure or downstream load of the valve can be timely and accurately fed back to the main valve diaphragm to adjust the opening of the main valve and ensure the stability of downstream pressure.

結(jié)構(gòu)特點(diǎn)：

■ 導(dǎo)閥彈簧：三種顏色的彈簧，可提供從0.2-14bar g范圍內(nèi)不同壓力的準(zhǔn)確控制。

■ 溫度調(diào)節(jié)刻度盤(pán)：快速準(zhǔn)確的設(shè)定所需溫度。

■ 溫度感應(yīng)器：在溫控元件中有無(wú)需補(bǔ)償?shù)囊后w，感應(yīng)瞬時(shí)溫度的變化，提供準(zhǔn)確的控制。

■ 測(cè)試每一個(gè)25系列的調(diào)節(jié)閥在出廠前都經(jīng)測(cè)試，以確保無(wú)故障的操作。

Structural features:

Pilot valve spring: Three colors of springs can provide accurate control of different pressures within the range of 0.2-14 bar g.

Temperature adjustment dial: quickly and accurately set the required temperature.

Temperature sensor: There is an uncompensated liquid in the temperature control element, which senses instantaneous temperature changes and provides accurate control.

Each 25 series regulating valve is tested before leaving the factory to ensure fault free operation.

工作原理：

25P蒸汽減壓閥，斯派莎克減壓閥啟動(dòng)前導(dǎo)閥彈簧處于自由狀態(tài)時(shí)，主閥和導(dǎo)閥處于關(guān)閉狀態(tài)。導(dǎo)閥由彈簧力作用打開(kāi)，蒸汽經(jīng)由導(dǎo)閥進(jìn)入主隔膜室，一部分蒸汽則經(jīng)由控制孔流出，當(dāng)由導(dǎo)閥流入的蒸汽大于由控制孔流出的蒸汽，主隔膜室中的控制壓力增大，打開(kāi)主閥。隨著蒸汽流過(guò)主閥，下游壓力的增量經(jīng)由感應(yīng)管反饋，作用在導(dǎo)閥膈膜下，平衡隔膜上部的彈簧壓力，使導(dǎo)閥逐漸關(guān)閉節(jié)流，維持主隔膜室中的壓力，控制主閥開(kāi)度輸送適量的蒸汽。調(diào)節(jié)導(dǎo)閥隔膜上的彈簧即可改變下游壓力。
