【進口可調(diào)式蒸汽減壓閥】詳細說明：

減壓閥，可用于蒸汽、壓縮空氣及其它氣體的壓力控制。下游壓力經(jīng)由內(nèi)部或外部的壓力感應(yīng)管反饋至壓力導閥，由主閥隔膜操作，調(diào)節(jié)主閥的開度。即使在上游壓力和蒸汽負載變化時，仍可準確的控制下游壓力。為了適應(yīng)不同的需要，減壓閥的閥體采用了不同的材質(zhì)，分別為球墨鑄鐵、鑄鋼和不銹鋼。對不同型號的閥，內(nèi)部組件采用統(tǒng)一的不銹鋼材質(zhì)，以方便維修保養(yǎng)和更換。

Pressure relief valve can be used for pressure control of steam, compressed air and other gases. The downstream pressure is fed back to the pressure guide valve through the internal or external pressure induction tube, which is operated by the main valve diaphragm to adjust the opening of the main valve. Even when the upstream pressure and steam load change, the downstream pressure can be accurately controlled. In order to meet different needs, the valve body of pressure relief valve adopts different materials, namely ductile iron, cast steel and stainless steel. For different types of valves, the internal components are made of uniform stainless steel to facilitate maintenance and replacement.

內(nèi)螺紋連接先導活塞式蒸汽減壓閥屬于先導活塞式減壓閥。由主閥和導閥兩部分組成。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。

The internal thread connection pilot piston type steam pressure reducing valve belongs to the pilot piston type pressure reducing valve. 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)式蒸汽減壓閥】工作原理：

1，本閥由閥體、波紋管組件、閥座、調(diào)節(jié)彈簧等組成，波紋管組件的閥桿和閥體相配合待波紋管受到介質(zhì)壓力后，推動閥桿移位，改變密封面與閥座間的距離。

2，本閥出廠時，密封面與閥座是關(guān)閉的，需要使用時，通過順時針方向旋轉(zhuǎn)螺絲，使調(diào)節(jié)彈簧壓向閥桿，頂開密封面。當受到介質(zhì)壓力時，介質(zhì)分二路，一路由閥體至出口，另一路由閥體上的平衡孔到波紋管的內(nèi)腔，并使閥桿向上和調(diào)節(jié)彈簧力的平衡。當進口壓力增加時，波紋管組件的閥桿向上移位，密封面和閥座之間的間隙減小，當調(diào)節(jié)彈簧和波紋管的力平衡時，則出口處的壓力就穩(wěn)定在需要值上，當進口壓力減小時則反向移動，仍使出口壓力穩(wěn)定在需要值上。
