进口先导活塞式蒸汽减压阀

德国巴赫进口先导活塞式蒸汽减压阀概述：

进口先导活塞式蒸汽减压阀属于先导活塞式减压阀。由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、缸套、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力、利用膜片传感出口压力变化，通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能。

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.

进口先导活塞式蒸汽减压阀主要用于蒸汽管路，起减压稳压作用。

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

进口先导活塞式蒸汽减压阀的定义：

进口先导活塞式蒸汽减压阀在普通减压阀基础上做了以下改进，加大了活塞面积，改变了节流结构。改变了密封形式，加大了过流面积等等，从而在提高灵敏度、流量、寿命等方面大大改善了性能。

使用优点：

1、提高了对出口压力变化的传感效能，提高了灵敏度，大大降低了因上游压力变化，流量变化等因素引起的压力偏差。
2、改善了流线分布，降低了噪声。
3、改进了密封面结构，延长了密封面寿命。
4、本质安全，可用于危险区域(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).
