進(jìn)口先導(dǎo)活塞式蒸汽減壓閥

德國(guó)巴赫進(jìn)口先導(dǎo)活塞式蒸汽減壓閥概述：

進(jìn)口先導(dǎo)活塞式蒸汽減壓閥屬于先導(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(pán)、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(guò)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(guò)導(dǎo)閥啟閉驅(qū)動(dòng)活塞調(diào)節(jié)主閥節(jié)流部位過(guò)流面積的大小，實(shí)現(xiàn)減壓穩(wěn)壓功能。

Import pilot piston type steam pressure reducing valve

Introduction of Bach inlet pilot piston steam pressure reducing valve:

Import pilot piston type steam pressure reducing valve belongs to the pilot piston type pressure reducing valve. By the main valve and pilot valve composed of two parts. The main valve mainly by the valve seat, the main valve plate, piston, cylinder liner, springs and other parts. Pilot valve is mainly composed of valve seat, valve disc, diaphragm, spring, adjusting spring and other parts. By adjusting the spring pressure to set the outlet pressure, the use of diaphragm sensing outlet pressure changes, through the pilot valve to open and close the piston to adjust the main valve throttle area over the size of the valve, to achieve the pressure regulator function.

進(jìn)口先導(dǎo)活塞式蒸汽減壓閥主要用于蒸汽管路，起減壓穩(wěn)壓作用。

Import pilot piston steam pressure relief valve is mainly used in the steam pipeline, from the role of pressure reduction.

進(jìn)口先導(dǎo)活塞式蒸汽減壓閥的定義：

進(jìn)口先導(dǎo)活塞式蒸汽減壓閥在普通減壓閥基礎(chǔ)上做了以下改進(jìn)，加大了活塞面積，改變了節(jié)流結(jié)構(gòu)。改變了密封形式，加大了過(guò)流面積等等，從而在提高靈敏度、流量、壽命等方面大大改善了性能。

使用優(yōu)點(diǎn)：

1、提高了對(duì)出口壓力變化的傳感效能，提高了靈敏度，大大降低了因上游壓力變化，流量變化等因素引起的壓力偏差。
2、改善了流線分布，降低了噪聲。
3、改進(jìn)了密封面結(jié)構(gòu)，延長(zhǎng)了密封面壽命。
4、本質(zhì)安全，可用于危險(xiǎn)區(qū)域(E型除外)。

Import pilot piston type steam pressure reducing valve:

Import pilot piston type steam pressure reducing valve on the basis of the general valve to do the following improvements, increasing the piston area, changing the throttle structure. Change the sealing form, increase the flow area and so on, so as to improve the sensitivity, flow, life and other aspects of greatly improved performance.

Use advantage:

1, improve the efficiency of the pressure change of the outlet, improve the sensitivity, greatly reducing the pressure changes due to upstream pressure, flow changes and other factors.

2, improve the streamline distribution, reduce the noise.

3, improve the sealing surface structure, prolong the sealing surface life.

4, intrinsically safe, can be used in hazardous areas (except E).
