进口可调式水用减压阀(德国OLES奥莱斯阀门)
【进口可调式水用减压阀】详细说明:
水用减压阀是采用控制阀体内的启闭件的开度来调节介质的流量,将介质的压力降低。水用减压阀同时借助阀后压力的作用调节启闭件的开度,使阀后压力保持在一定范围内,在进口压力不断变化的情况下,自来水减压阀保持出口压力在设定的范围内,保护其后的生活生产器具。采用了全通道流线型设计,流本阻力小,流量大。在传动方式上采用了水力操作,即利用管路中的水压自动操作主阀盘的下下移动,控制阀门开度,调节下游压力,使下游压力维持在导阀弹簧设定的压力值上。当下游压力超过设定值时,水用减压阀将自动关闭,不管入口压力怎样波动,都可输出稳定的出口压力,不管下游流量怎样变化,都能维持出口压力稳定在导阀设定值上。同时通过导阀调节的出口压力,调节范围大,可达阀前压力10-80%,且工作平稳,无水锤冲击现象。
The water pressure relief valve uses the opening of the opening and closing parts in the control valve body to regulate the flow rate of the medium and reduce the pressure of the medium. At the same time, the opening of the opening and closing parts of the water pressure relief valve is regulated by the function of the back pressure of the valve, so that the back pressure of the valve can be kept within a certain range. In the case of constant changes in the import pressure, the tap water pressure relief valve keeps the outlet pressure within a set range and protects the subsequent life and production equipment. The whole channel streamlined design is adopted, with small flow resistance and large flow rate. Hydraulic operation is adopted in the transmission mode, that is, the water pressure in the pipeline is used to automatically operate the lower movement of the main valve disc, control the opening of the valve and regulate the downstream pressure, so that the downstream pressure is maintained at the pressure value set by the guide valve spring. When the downstream pressure exceeds the set value, the water pressure relief valve will automatically close. No matter how the inlet pressure fluctuates, the stable outlet pressure can be output. No matter how the downstream flow changes, the outlet pressure can be maintained at the set value of the pilot valve. At the same time, the outlet pressure regulated by the guide valve can reach 10-80% of the pre-valve pressure, and work smoothly without water hammer impact.
【进口可调式水用减压阀】工作原理:
减压阀的工作原理建立在两基本点压力平衡的基础上:
1.弹簧向下施加的开启活塞力量。
2.膜片向上的作用的关闭活塞的力量。
【进口可调式水用减压阀】特点:
水用减压阀为内螺纹连接,由阀体、阀盖、压缩弹簧、阀杆及膜片等组成,采用阀后压力直接传递作用于膜片下方并与膜片上方压力保持*平衡状态的结构。水用减压阀具有动作灵敏、快捷、性能可靠、使用寿命长、形体小巧、易于安装等特点、使其更加安全可靠。

2、丝扣减压阀耐脏防水垢,不需过滤器,不需旁通管,配管极其简单,能节省大量空间和配管成本。
3、减压阀出口压力精密可调。
4、本减压阀大水力特性,压力损失小,流量损失小,阀后压力0.5-6公斤可调节,大耐压16公斤。
5、可满足多种减压要求,特别适用于支路减压阀系统。
安装调节:
1.水用减压阀主阀的*安装方式是水平卧式安装,其他安装方式也可达到操作功能。减压阀安装前要*清除管道内的杂物,要注意主阀体外水流标标箭头,遵循方向安装,安装后应确保没有管路应力作用在阀体 及阀内部件上。
2.主阀前要安装一只闸阀和一只过滤器,主阀后也要装一只闸阀,以便于维修。
3.水用减压阀导阀与导管控制系统已于出厂前装配和调整完毕,如导阀出厂设定压力值不适合现场要求,可通过拧紧或放松导阀上端螺钉来调节,顺时针拧动螺钉为增加压力,逆时针拧动螺钉为减少压力,调节完 后拧紧锁紧螺母。
4.主阀上的微型过滤器要定期清洗。
5.通水前的须*冲洗管路系统。
6.对重要给水管路应安装旁通阀
