Its performance is more superior, completely replace the intermediate water tank, save the cost of building the intermediate water tank, and expand the use area of the building.
安装要求及示意图
安装请参考可调式减压阀安装要求和以下要求：
1、建议在管网系统中安装排气阀，以便减压阀能稳定工作。
2、安装时应注意阀体箭头标注方向。为方便维护保养应在减压阀周围留一定空间。
3、进出口压力应不小于0.2Mpa,小于0.2Mpa稳压性能变差(出口压力误差加大)。
Installation requirements and schematic diagram
Please refer to the installation requirements of the adjustable pressure reducing valve and the following requirements:
1, it is recommended to install an exhaust valve in the pipe network system, so that the pressure reducing valve can work stably.
2. Pay attention to the direction marked by the arrow of the valve body during installation. In order to facilitate maintenance, leave a certain space around the pressure reducing valve.
3, the import and export pressure should not be less than 0.2Mpa, less than 0.2Mpa pressure regulator performance deteriorates (outlet pressure error increases).

结构特点
可调式减压阀阀就是用水压控制的阀门，它由一个主阀及其附设的导管、导阀、针阀、球阀和压力表等组成。根据使用目的、功能及场所的不同可演变成遥控浮球阀、减压阀、缓闭止回阀、流量控制阀、泄压阀、水力电动控制阀等水力控制阀分隔膜型和活塞型两类，工作原理相同，都是以上下游压力差△P为动力，由导阀控制，使隔膜(活塞)液压式差动操作，完全由水力自动调节从而使主阀阀盘完全开启或完全关闭或处于调节状态。当进入隔膜(活塞)上方控制室内的压力水被排到大气或下游低压区时，作用在阀盘底部和隔膜下方的压力值就大于上方的压力值，所以将主阀阀盘推到完全开启的位置，当进入隔膜(活寒)上方控制室的压力水不能排到大气或下游低压区时，作用在隔膜(活塞)上方的压力值就大于下方的压力值，所以就会把主阀阀盘压到完全关闭的位置，当隔膜(活塞)上方控制室内的压力值处于入口压力与出口压力中间时，主阀阀盘就处于调节状态，其调节位置取决于导管系统中的针阀和可调导阀的联台控制作用。可调导阀可以通过下游的出口压力并随它的变化而开大或关小其自身的小阀口，从而改变隔膜(活塞)上方控制的压力控制主阀阀盘的调节位置。
Structural characteristics
The adjustable pressure reducing valve is a valve controlled by water pressure, which is composed of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. According to the purpose of use, function and different places can be evolved into remote control float valve, pressure reducing valve, slow closing check valve, flow control valve, pressure relief valve, hydraulic electric control valve and other hydraulic control valves are divided into diaphragm type and piston type two categories, the working principle is the same, are the above downstream pressure difference △P as the power, controlled by the pilot valve, so that the diaphragm (piston) hydraulic differential operation, Fully hydraulically self-regulated so that the main valve disc is fully open or fully closed or in the regulated state. When the pressure water entering the control room above the diaphragm (piston) is discharged to the atmosphere or downstream low pressure area, the pressure value acting on the bottom of the valve disc and under the diaphragm is greater than the upper pressure value, so push the main valve disc to the fully open position, when the pressure water entering the control room above the diaphragm (cold) cannot be discharged to the atmosphere or downstream low pressure area, The pressure value above the diaphragm (piston) is greater than the pressure value below, so the main valve disc will be pressed to the completely closed position, when the pressure value of the control chamber above the diaphragm (piston) is in the middle of the inlet pressure and the outlet pressure, the main valve disc is in the adjustment state, the adjustment position depends on the needle valve and the adjustable pilot valve in the guide system. The adjustable pilot valve can open or close its own small valve port through the downstream outlet pressure and change with it, thereby changing the pressure controlled above the diaphragm (piston) to control the adjustment position of the main valve disc.
