Description

Air water hammer eliminating silencing valve
Technical field
The invention belongs to the machinery valve series products, relate to the noise reduction valve of a kind of universal class of the water hammer of water delivery (oil) pipe-line system and noise that a variety of causes causes, relate in particular to a kind of air water hammer eliminating silencing valve.
Background technique
In the water supply pipline system of every height, long-range (particularly open circuit water supply) at the automatic start-stop of pumping (or pumping accident), or in the little oil-way system of viscosity, during termination of pumping because pressure jump produces the water hammer pressure ripple, atmospheric pressure when adding the pipe water outlet cutout will inevitably produce strong water hammer.The water hammer fecund occurs with water hammer pressure ripple and vibration mode from the high-end outlet port of water (oil) pipeline, and frequency is higher, and instantaneous pressure is bigger.Cause pipeline, the safety check in the pump house (low level) and be fixed in pipe holder on the wall, under the intense impact vibration of this repeated multiple times, all fatigue fracture might take place.Facts have proved, in the pipe-line system that only adopts slow closed check damper, noise and collapsing force that still difficult elimination water hammer causes.
In cold and hot water supply that industry, commercialization or resident use, pipeline road system, (the high-frequency noise that produces when for example opening valve or water tap sometimes usually for various reasons, in the water delivery oil transportation process, sometimes eddy current occurs owing in the pipe, stream or air pocket, and generation low-frequency vibration noise etc.) influence, polluted environment.
No matter the water hammer pressure ripple what reason causes, the noise of different frequency range, it all reflects pipeline pressure sudden change and vibration, all is a kind of impact shock energy.For fear of the loine pressure sudden change, slow closed check damper has been adopted in design once, heavy hammer type water-hammer arrester, and the good several multi-form gas water-hammer arresters that occur on the market in recent years.All there is different big and small defectives in they.Because the gas compression rate is very big, and the compressibility of water (or oil) very little (so also this characteristic water hammer and noise usually take place) just.Water hammer ripple moment impact pressure very big though (can reach 3-5 doubly), but water (oil) Volume Changes is very little.
Summary of the invention
The objective of the invention is to: overcome the deficiency on the prior art, provide that a nested structure is novel simple, volume is little, easily processing, cost are low, reliable and practical effective, simplify pipe-line system facility saving investment, energy-saving and cost-reducing, convenient management, the air water hammer eliminating silencing valve of dual-use.
The present invention realizes by following scheme: comprise valve chest and termination link, by inflation, air water hammer eliminating noise reduction in the valve chest are combined with valve and eliminate water hammer and pipeline noise, valve chest is provided with filling gas mouth, axially be provided with the air chamber leather sheath in the valve chest, air chamber leather sheath top and termination link are affixed, the bottom is connected with the valve chest bottom, the valve chest inner chamber is provided with the biconial spool, interior dress is used to regulate the weight of weight, top and bottom are provided with the positioning and guiding bar, and all cooperate with pilot hole on the link of termination.
Air chamber leather sheath inwall of the present invention is provided with the balance guard.
Balance guard of the present invention is made by porous slab; Pressure gauge is set on the valve chest.
The present invention is equipped with seal ring at air chamber leather sheath upper and lower end, and is configured as one with it.
Air chamber leather sheath of the present invention is made by rubber.
The weight that is used to regulate weight of the present invention is husky for doing.
The present invention has following feature: one, the air chamber rubber cover of straight-through band seal ring is placed between valve chest and the balance guard, add termination flange short tube (or blind flange, wire connection short tube), the sealed air chamber that has just formed a constant volume, in air chamber, fill the air of suitable pressure, just can receive positive and negative water hammer and noise in the pipeline.Air chamber rubber cover and balance guard can specification seriesization, in the air water hammer eliminating silencing valve of all styles of of same size, can generally exchange, processing, assembling and maintenance have been made things convenient for, improve socio-economic efficiency and benefit, the air chamber rubber cover of straight-through band seal ring is convenient to processing, efficient is high and be difficult for waste product, and is more much lower than the processing cost of closed air bag; Two, permeability is good, the straight-through type balance guard that the porous stainless steel plate that penetrating area is big is made, the liquid in the single tube road does not have good gross area to contact with air chamber rubber cover internal surface, can receive water hammer and noise in the pipeline rapidly reliably, simultaneously it also plays a part support fixation and air chamber rubber cover position; Three, the diconical hollow spool of combined type, its effect one, overall weight can overweight from the buoyancy in liquid it, simultaneously convenient and swift again closing volume fluid passage with the regulation and control of dry sand slightly.Single-unit has not been made an appointment with the metallic material cost like this, has also reduced running resistance simultaneously, saves power source.Two is the biconial of cone, and is actual close with fairing, is for flow of fluid does not produce eddy current and streams through out-of-date, reduces running resistance, energy-saving and cost-reducing.The lower end conical surface is the quick for convenience accurately passage of closing volume liquid simultaneously; Four, ingeniously ideally gas water-hammer arrester and various forms of General valve are combined, will eliminate water hammer simultaneously and eliminate the noise that a variety of causes produces and combine, make it become the air water hammer eliminating silencing valve of entity-different patterns.In the pipe network of confession (failing) water for (failing) oil of all lengths, different purposes, all can choose needed air water hammer eliminating silencing valve, satisfactorily resolve the trouble that water hammer and noise cause.
The present invention is with air water hammer eliminating noise reduction mode and the ingenious perfect adaptation of various forms of General valve, dual-use.Novel structure, volume are little, interchangeable, the general combination in the various water hammer eliminating silencing valve of same size of major function structure member, but seriation, standardization.Various water hammer eliminating silencing valve does not all have any rapid wear and easily causes dyskinetic component, and operation is sensitive reliable, and the life-span is long, and the hammer good muffling effect disappears.Can adopt common used material, requirement on machining accuracy is general, manufacturing easily, and the cost poor benefit is good.In various water delivery, pipeline road, the product of the present invention of suitably matching corresponding form all can reach quick rapidly, the sensitive promising result of eliminating water hammer and various noises reliably.The present invention is the same with common valve not to exist potential problem dangerous or that pollute.Easy to install reliable, do not need the special messenger to supervise maintaining at ordinary times.
The present invention is from the principle to the structure, and the letter joint is lucid and lively, analyzes its feature, and each part all has practical experience and science, economic design concept.It ideally embodies science, advance, sensitive reliability, practicability and Economy, makes the elimination of water hammer and noise become simple.The water supply pipline system facility has been simplified, and construction investment has been saved, and has reduced the facility resistance, energy-saving and cost-reducing, operating cost has reduced.
