Y43H pilot piston type steam pressure reducing valve

Y43H先导活塞式蒸汽减压阀在城市建筑、高层建筑的冷热供水系统中,可取代常规分区水管,节省设备。也可在通常的冷热水管网中,起减压稳压作用。本产品调压、稳压动作平稳,适用于水和非腐蚀性液体介质的管路。

Y43H pilot piston type steam pressure reducing valve can replace the conventional zone water pipe and save equipment in the cold and hot water supply system of urban buildings and high-rise buildings. It can also play the role of reducing pressure and stabilizing pressure in the common cold and hot water pipe network. The product has stable pressure regulating and stabilizing action and is suitable for water and non corrosive liquid medium pipelines.

蒸汽减压阀结构特点和用处:

Structure features and use of steam pressure reducing valve:

本系列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、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。

This series of pressure reducing valve belongs to pilot piston type. It is composed of main valve and pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, regulating spring and other parts. By adjusting and adjusting the spring pressure to set the outlet pressure, using the diaphragm to sense the outlet pressure change, and driving the piston through the pilot valve to adjust the size of the flow area of the throttle part of the main valve, the pressure reducing and stabilizing function is realized

主产品主要用于蒸汽管路,起减压稳压作用。

The main product is mainly used for steam pipeline, which can reduce pressure and stabilize pressure.

减压阀Y43H-16,备有0.05~0.4MPa,Y43H-25,备有1~1.6MPa,Y43H-40,备有1~1.6MPa,1.6~2.5MPa调节弹簧,Y43H-64,备有1~3MPa调节弹簧,出厂时阀内装有0.1~1MPa,弹簧,其余随阀附带,用户可根据所量的出口压力值选装。

The pressure reducing valve y43h-16 is equipped with 0.05-0.4mpa, y43h-25, 1-1.6mpa, y43h-40, 1-1.6mpa, 1.6-2.5mpa regulating spring, y43h-64 and 1-3mpa regulating spring. When leaving the factory, the valve is equipped with 0.1-1mpa spring. The rest is attached with the valve. The user can choose according to the measured outlet pressure value.

装减压阀之前必须对管路系统进行冲洗清理。以防焊渣,氧化皮等赃物流入阀内,影响阀门正常工作。

Before installing the pressure reducing valve, the pipeline system must be flushed and cleaned. In order to prevent welding slag, oxide skin and other dirt into the valve, affect the normal operation of the valve.

阀应安装在便于操作和维修的地方,并且必须直立安装在水平管道上,应注意使管路中介质的流向与阀体上箭头所示方向一致,切勿反装。

The valve shall be installed in a place convenient for operation and maintenance, and must be installed vertically on the horizontal pipeline. Attention shall be paid to make the flow direction of the medium in the pipeline consistent with the direction indicated by the arrow on the valve body, and do not reverse install.

减压阀在安装使用时,应把旁通管道的截止阀打开,排除管路中的冷凝水和汽水的混合物,以防减压阀开启时产生水圾现象损坏减压阀,当无异常现象后,按顺时针方向缓慢旋转调节螺钉,将出口压力调至所需的压力(以阀后表压为准),调整后,将锁紧螺母背紧,拧上防护罩。

When the pressure reducing valve is installed and used, the stop valve of the bypass pipe shall be opened to remove the mixture of condensate and steam water in the pipe, so as to prevent the water waste from damaging the pressure reducing valve when the pressure reducing valve is opened. When there is no abnormal phenomenon, slowly turn the adjusting screw clockwise to adjust the outlet pressure to the required pressure (the gauge pressure behind the valve shall prevail). After adjustment, back tighten the lock nut, Screw on protective cover.

减压阀前应安装过滤器,以防介质中的杂物进入减压阀,影响其性能。

A filter shall be installed before the pressure reducing valve to prevent the sundries in the medium from entering the pressure reducing valve and affecting its performance.

安装的减压阀前后应有一段直管,阀前的直管长度约为600毫米,阀后的直管长度约为1毫米。

There should be a section of straight pipe in front of and behind the installed pressure reducing valve. The length of straight pipe in front of the valve is about 600mm, and the length of straight pipe behind the valve is about 1mm.

一般减压阀都要求进出口压差必须≥0.2Mpa。

Generally, the pressure difference between the inlet and outlet of the pressure reducing valve must be ≥ 0.2MPa.
