Abstract

The invention relates to a pressure limiting and stabilizing valve, pertains to the pressure controlling arrangement for tap water, which comprises a water inlet, a casing of a water outlet, and an upper cover and a lower cover. The upper cover is sealedly connected with the casing through a flexible upper seal film; the lower cover is sealedly connected with the casing through a flexible lower seal film; between the water inlet and the water outlet, a partition board with a water-through port is provided; between the upper and the lower cover, a control rod is provided; the inner and outer side of the flexible upper seal film and the flexible lower seal film are provided with an upper cover support, an upper film presser, as well as a lower cover support and a lower film presser for sealedly connecting the controlling rod; on the controlling rod, a seal piece corresponding to the water-through port is fixed; the partition board is connected with a limit; on the controlling rod between the limit and the lower film presser, a spring is provided. The invention is of small size, high strength, high practicability, integrates a plurality of such functions as pressure limiting, stabilizing, and water-hammer eliminating, etc., allows the end users of the water supply pipe network from the municipal engineering not worrying about any water leakage because the water treatment system is damaged by high pressure.

Description

[0001] The invention relates to a tap water pressure control device. Technical field: [0002] The invention is mainly used for the terminal of the pipeline water delivery system, and uses the special structure of the pressure limiting valve to close the pipeline when the water pressure of the pipeline increases to a certain value, effectively controlling the pressure fluctuation of the water delivery pipeline network and eliminating the water hammer, so as to Avoid terminal water equipment being damaged by high water pressure. Background technique: [0003] The technology currently used is a single water hammer eliminator or pressure reducing valve, which adopts the method of small hole decompression and soft materials such as rubber for cushioning. This method is suitable for large-scale water delivery systems, and can only partially eliminate water hammer, but there is no such product used at the end of municipal water supply systems. Invention content: [0004] The pu...
