The present invention relates to a pressure limiting valve tap water pressure control device; it is composed of a water inlet and a water outlet of the shell and the upper and lower cover, the upper cover through the flexible sealing membrane and shell sealing connection; seal under cap is connected by flexible seal membrane and shell; a baffle band nozzle in between the water inlet and the water outlet; the upper and lower cover is arranged between the control rod; sealing connection lever for flexible upper and lower sealing film on the inner side and the outer side is equipped with support, support, and film tablet film under compression; the control rod is fixed with the sealing piece through the nozzle corresponding to the connecting piece; partition Co., limited control lever. A piece and the lower sealing film with compression spring; the invention has the advantages of small size, high strength, strong practicability, pressure limiting and stabilizing and eliminating water hammer of multi functional, the end users don't have to worry about the municipal water supply pipe network for water The treatment system is damaged by high pressure, resulting in a drainage event.
【技术实现步骤摘要】
本专利技术主要用于管道输水系统终端，利用限压阀的特殊结构，在管路的水压增大到一定值时封闭管路，有效控制输水管网的压力波动并消除水锤，以避免终端用水设备被高水压造成破坏。
技术介绍
目前使用的技术为单一的水锤消除器或减压阀，它采用的是小孔 减压和橡胶等软质材料缓冲的方法。此种方法适用于大型输水系统， 且只能部分消除水锤，而在巿政供水系统终端尚无该类产品的使用。
技术实现思路
本专利技术的目的在于提供一种保证自来水用水安全的限压稳压阀。 它由带有进水口及出水口的外壳和上、下盖组成，上盖通过柔性上封膜与外壳密封连接；下盖通过柔性下封膜与外壳密封连接；在进 水口与出水口之间设有带通水口的隔板；上、下盖之间设控制杆。柔性上、下封膜的内、外两侧配有上盖托、上膜压片和下盖托、 下膜压片用于密封连接控制杆。控制杆上固定有与通水口对应的密封片。隔板连接有限位片，限位片与下封膜压片之间的控制杆上配有弹本专利技术其优点是体积小、强度高、实用性强、限压、稳压和消 除水锤等多功能合一。可使巿政给水管网的终端用户不必担心因水处 理系统受到高压破坏而造成泄水事件。附图说明附图l是本专利技术的主...
