進口可調(diào)式膜片式減壓閥(德國OLES奧萊斯)

【進口可調(diào)式膜片式減壓閥】詳細(xì)說明:

隔膜可調(diào)式減壓穩(wěn)壓閥是安裝于高層建筑給排水系統(tǒng)管道上，將進口壓力臧至某一需要的出口壓力的特種閥門。隔膜式可調(diào)減壓閥依靠本身能量使出口壓力保持穩(wěn)定在設(shè)定值，即出口壓力不因進口壓力及流量的變化而變化并且閥門控制系統(tǒng)的進口處裝有一個自清潔濾網(wǎng)，利用流體特性，使比重較大、直徑較大的懸浮顆粒不會進入控制系統(tǒng)．確保系統(tǒng)循環(huán)暢通無阻，使閥門能安全可靠地運行。系統(tǒng)動作靈敏，使用壽命長。

Diaphragm adjustable pressure reducing and stabilizing valve is a special valve which is installed in the water supply and drainage system of high-rise buildings, and it can evaluate the import pressure to a certain required outlet pressure. Diaphragm-type adjustable pressure relief valve relies on its own energy to keep the outlet pressure stable at the set value, that is, the outlet pressure does not change with the change of inlet pressure and flow rate, and a self-cleaning filter is installed at the inlet of the valve control system. By utilizing the fluid characteristics, the suspended particles with larger specific gravity and diameter will not enter the control system. To ensure the smooth circulation of the system, so that the valve can operate safely and reliably. The system operates sensitively and has a long service life.

【進口可調(diào)式膜片式減壓閥】結(jié)構(gòu)特點：

本系列減壓閥屬于先導(dǎo)活塞式減壓閥。由主閥和導(dǎo)閥兩部分組成。主閥主要由閥座、主閥盤、活塞、缸套、彈簧等零件組成。導(dǎo)閥主要由閥座、閥瓣、膜片、彈簧、調(diào)節(jié)彈簧等零件組成。通過調(diào)節(jié)調(diào)節(jié)彈簧壓力設(shè)定出口壓力，利用膜片傳感出口壓力變化，通過導(dǎo)閥啟閉驅(qū)動活塞調(diào)節(jié)主閥節(jié)流部位過流面積的大小，實現(xiàn)減壓穩(wěn)壓功能。本產(chǎn)品主要用于蒸汽管路，起減壓穩(wěn)壓作用。

This series of pressure relief valves belong to pilot piston type pressure relief valves. It consists of main valve and pilot valve. The main valve is mainly composed of seat, main disc, piston, cylinder liner, spring and other parts. The guide valve is mainly composed of seat, disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting the spring pressure, the diaphragm is used to sense the outlet pressure change, and the pilot valve is used to open and close the driving piston to adjust the size of the throttle area of the main valve so as to realize the function of reducing pressure and stabilizing pressure. This product is mainly used in steam pipeline, which can reduce pressure and stabilize pressure.

【進口可調(diào)式膜片式減壓閥】性能:

可調(diào)式減壓穩(wěn)壓閥減小較高的上游壓力并產(chǎn)生一個穩(wěn)定的較低的下游壓力,不受上游壓力或流量變化的影響。 可調(diào)式減壓穩(wěn)壓閥既可減動壓又可減靜壓. 閥門下游壓力可依據(jù)系統(tǒng)要求在一定范圍內(nèi)連續(xù)可調(diào) 。閥門在其下游管線突然關(guān)閉的情況下可以迅速關(guān)閉以減靜壓。一般情況下，所得閥后壓力不會高于相應(yīng)的動壓的10%。可調(diào)式減壓閥是由管道壓力啟動，導(dǎo)閥自動控制，既減動壓、又減靜壓的減壓閥。閥門將減小較高的上游壓力并產(chǎn)生一個穩(wěn)定的較低的下游壓力，不受上游壓力和流量變化的影響。所獲得的下游壓力可根據(jù)需要通過調(diào)節(jié)減壓導(dǎo)閥上的螺栓來改變.。當(dāng)上游壓力降至所需壓力設(shè)定值時,導(dǎo)閥使主閥開至zuida程度。當(dāng)下游壓力超過設(shè)定壓力值時(例如，在消防栓系統(tǒng)中由于減壓閥門下游管線水不流動所產(chǎn)生的靜壓情況下)，可調(diào)式減壓穩(wěn)壓閥立即關(guān)閉以減靜壓，所以不但可以滿足常規(guī)供水系統(tǒng)的減壓要求，而且對于更苛刻的消防靜壓保持系統(tǒng)，也有*的可靠性，從根本上避免了串壓等系統(tǒng)問題。
