Abstract
The present invention provides a high-speed gas exhaust valve with full pressure. The present invention is arranged on a pipeline for transporting water or other liquids, and is used for exhausting gases in the pipeline, and thus, the present invention conveniently protects the pipeline against the destroy by gas explosion and enhances the water transportation efficiency. The present invention is characterized in that the gas is exhausted at high speed under any condition, especially under the alternate condition of a plurality of sections of water columns and gas columns.
Description
Technical field: the present invention relates to a kind of pipeline exhaust and protecting water hammer device outlet valve.Outlet valve generally is used for water supply line, be mainly used to get rid of ducted gas, and when vacuum occurring in the pipeline to the pipeline gas injection to prevent from the pipeline to produce gas explosion and cutout water hammer, simultaneously, in time get rid of ducted gas, also can eliminate because of air mass reduces the water resistance increase that the pipeline flow cross-section produces, it is energy-conservation to help water supply piping system.
Background technique: the outlet valve that has earlier is divided into two kinds of patterns.Be the assemblying body of Single Opening Exhaust Valves, high-speed exhaust valve or these two kinds of valves, claim the twoport outlet valve, outlet valve generally is contained in and is embedded in underground having on the water supply line of pressure, and its effect is the gas in the discharge conduit, in case the pipeline gas explosion.
All can discharge gas for satisfying under any condition, the relief opening of Single Opening Exhaust Valves is generally very little, can't satisfy the needs than a large amount of exhausts of large pipeline.Its working principle is, after the gas of main pipe enters outlet valve, and ball float loss of buoyance and falling in the casing, thus opening relief opening 5 makes the outlet valve exhaust, and after water entered valve, ball float floated, and blocks relief opening water is not outflowed.High-speed exhaust valve and Single Opening Exhaust Valves structure are identical, and just relief opening becomes big.
Its working principle is also identical with Single Opening Exhaust Valves, the purpose that strengthens relief opening is to increase extraction flow, but the ball float that gets lodged on the relief opening is subjected to very big " gas holder " power, its theoretical value equals the product of pipeline external and internal pressure difference and exhaust valve port area, it is much larger than the weight of ball float, make ball float can't fall into casing and open relief opening, thereby lose scavenging action.Because water supply line water-filling and the normal alternate state of aqueous vapor that often is in service, this high-speed exhaust valve in fact can't the high speed exhausts, this problem is that bundle is disturbed the difficult problem of engineering circle in decades always, and has caused a large amount of engineering accidents.
Summary of the invention: the present invention aims to provide a kind of full-pressure high-speed exhaust valve, so-called full-pressure high-speed exhaust valve, but i.e. all high speed exhausts under whole working pressures of pipeline and the alternate state of aqueous vapor.The characteristics that it had are: after the gas in the pipeline enters outlet valve, the floating drum loss of buoyance that hangs in the valve body on float lever one end falls, the small valve core of the float lever the other end is risen, open little valve port, and close relief opening on the little smoke releasing cap, make the gas channel conduit enter oil hydraulic cylinder, diaphragm unit in the oil hydraulic cylinder is subjected to gas pressure to open cover plate on the big relief opening on the valve body, realizes the high speed exhaust, and after water enters exhaust valve, floating drum rises, small valve core descends, and closes little valve port, opens the relief opening on the smoke releasing cap simultaneously, make oil hydraulic cylinder by the straight-through atmosphere of the relief opening on conduit and the smoke releasing cap, the diaphragm decompression, the cover plate on the big relief opening is closed under the effect of pipeline hydraulic pressure, and big relief opening is blocked current, thereby there is gas promptly to open big relief opening exhaust, the effect that has water just to close in the realization exhaust valve.
Description of drawings: the present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing is the sectional drawing of a kind of concrete structure of the present invention.
With reference to accompanying drawing, full-pressure high-speed exhaust valve of the present invention is mainly by following valve body 14, middle valve body 16, float lever 12, small valve core 10, cover plate 1, piston rod 2, diaphragm 5 and valve gap 3 are formed, and floating drum 15 is hinged by pin 13 and float lever 12, float lever 12 by twist solid main shaft 11 on middle valve body 16 be hinged on the valve body, and by control the lifting of small valve core 10 from sulculus on one's body.In valve body 16 fuse by bolt and valve body 14, and floating drum 15 is positioned within the casing on the valve body 14.Cover plate 1, pressure ring 4, diaphragm 5, diaphragm top board 6 fuse under piston rod 2 and the diaphragm, form the operation control unit, and diaphragm 5 is pressed on the middle valve body 16 by valve gap 3, valve body 16 was communicated with oil hydraulic cylinder inner chamber on the valve gap 3 during conduit 8 made by joint 7, and the float gas cap is consolidated on middle valve body 16 by stubborn.
Embodiment: this full-pressure high-speed exhaust valve generally is loaded on the ridge of transporting water or other fluid pipelines, when having gas in the pipeline, it is generally assembled to ridge, valve body 14 inner chambers are with gassy, floating drum 15 is because of falling within the valve body under the action of gravity, driving small valve core 10 by float lever simultaneously rises, block the relief opening on the smoke releasing cap 9, and the little valve port on the valve body 16 makes gas enter the oil hydraulic cylinder that valve gap 3 and diaphragm 5 etc. are formed by conduit 8 in opening, under the effect of hydraulic pressure cylinder pressure, diaphragm 5 pressurizeds produce a downward active force, this active force is greater than the active force that makes progress suffered on the cover plate 1, thereby whole motion assembly moves down, and the big relief opening in opening on the valve body 16 is realized the high speed exhaust.After gas emptying in the pipeline, liquid enters valve body, and under buoyancy function, floating drum 15 rises, spurring small valve core 10 simultaneously descends, cover the little valve port on the valve body, and open relief opening, make decompression in the hydraulic cylinder cavity, even move on the whole motion assembly of cover plate 1 suffered upward force, and cover big relief opening, and it is closed, do not make the liquid outflow.
