Abstract
The utility model relates to a tap water pressure control device, especially a pressure limiting and maintaining valve, which comprises a crust with a water inlet and a water outlet, an upper cover and a lower cover, wherein the upper cover is tightly fitted with the crust through a flexible pulling film, the lower cover is tightly fitted with the crust through a flexible pushing film, a clapboard with limber hole is provided with the water inlet and the water outlet, a control rod is provided between the upper and the lower covers, the flexible pulling and pushing film is arranged on the inner and outer surface with an upper cover support, a pulling film plate, a lower cover and a pushing film plate to tightly fit the control rod, the control rod is fixed with a sealing plate corresponding to the limber hole, the clapboard is connected with a limit plate, a spring is arranged on the control rod between the limit plate and the pushing film pressure plate. The utility model is small in volume, high in intensity and practicability and has a combinational function of pressure limiting and water hammer eliminating, which frees the municipal water supply pipe network terminal client from worrying about draining incident caused by the water-treatment system being damaged by high pressure.
Description
Technical field:
The utility model relates to the tap water pressure control gear.
The utility model is mainly used in the water delivery in pipeline system terminal, utilize the special construction of pressure-limit valve, closing pipe line when the hydraulic pressure of pipeline increases to certain value is effectively controlled the pressure surge of water transfer pipe network and is eliminated water hammer, is damaged by high hydraulic pressure to avoid the terminal watering equipment.
Background technique:
The technology of using is single water-hammer arrester or reduction valve at present, and what it adopted is the method for soft material bufferings such as aperture decompression and rubber.This kind method is applicable to large-scale water-carriage system, and can only partly eliminate water hammer, and does not still have the use of this series products at the municipal water supply system terminal.
Summary of the invention:
The purpose of this utility model is to provide a kind of pressure-limiting stabilizing valve that guarantees the tap water water safety.
It is made up of shell that has water intake and water outlet and upper and lower cover, and loam cake is connected with body seal by flexible upper sealing film; Lower cover is connected with body seal by flexible lower sealing film; Between water intake and water outlet, be provided with the dividing plate of band inlet; Establish controlling rod between the upper and lower cover.
The inside and outside both sides of flexible upper and lower envelope film are furnished with loam cake holder, upward mould sheet and lower cover holder, the mould sheet is used to the controlling rod that is tightly connected down.
Be fixed with the diaphragm seal corresponding on the controlling rod with inlet.
Dividing plate is connected with banking stop, is furnished with spring on the controlling rod between banking stop and the lower sealing film compressing tablet.
Its advantage of the utility model is: multi-functional unification such as volume is little, intensity is high, practical, pressure limiting, voltage stabilizing and elimination water hammer.Can make the terminal use of municipal water supply pipe network needn't worry to destroy the sluicing incident that causes because of water treatment system is subjected to high pressure.
