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
The present invention relates to the tap water pressure control gear.
Technical field:
The present invention 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 object of the present invention 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 present invention 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.
Description of drawings:
Accompanying drawing 1 is a main pseudosection of the present invention.
