Abstract
The invention discloses a water hammer self-balancing swing one-way valve. The water hammer self-balancing swing one-way valve is characterized by comprising a valve plate with a flow discharging hole and a water hammer self-balancing device, wherein the water hammer self-balancing device is characterized in that the flow discharging hole is formed in the valve plate; a flow discharging hole sealing plate fixing bracket is fixed at the periphery of the flow discharging hole; a guide shaft is arranged on one side of the sealing plate; a closing-supporting spring is arranged between the fixing bracket and the sealing plate; the spring is mounted on the guide shaft; one side of the spring is supported on the fixing bracket. Compared to the prior art, the water hammer self-balancing swing one-way valve has the advantages that the flow discharging hole is formed and used for discharging water flow of the water hammer, the water hammer is effectively avoided, the spring is used for pushing the sealing plate, setting damping force and effectively absorbing the water hammer, the structure is novel, the valve is safe and reliable, the valve has an excellent water hammer prevention function and a wide range of application.
Description
Technical field
The invention belongs to water hammer-resistant safety check technical field, relate to the safety check that a kind of valve plate is provided with discharge orifice, particularly a kind of water hammer self balancing being provided with spring assembly at valve plate discharge orifice is revolved and is opened safety check.
Background technique
Safety check (One-way valve) is also known as one-way valve or check valve, its effect prevents the medium in pipeline from flowing backwards, and safety check belongs to self-acting valve class, is mainly used on the pipeline of medium one-way flow, medium is only allowed to flow to a direction, to try to avert accidents.When suction side pressure is lower than outlet side, flap automatically by pathway closure, stops fluid countercurrent current under the effect of hydrodynamic pressure and gravity own.Press flap motion mode different, safety check is mainly divided into rise-fall type, rotary-open type, butterfly and water conservancy control formula etc.Safety check is as too fast in cut out, and may cause water attack in fluid pipeline, also known as water hammer, produces noise, even causes the damage of valve parts and water supply line.For avoiding this situation, the safety check of pooling feature can be selected when needing, to extend the shut-in time, Slow Close measure is forced in being of current employing, such as Tiny Drag Slow Shut Check Valves, micro-resistance slowly-closed butterfly check valve, fluid power Self force valve etc., comprise water conservancy and control class safety check, as multifunctional water pump control valve, it is the slowly closing that realized valve plate by upper and lower chamber by the forceful action of diaphragm to the processing mode of water hammer harm, still not to the prevention of water hammer with receive function.
summary of the invention:
The object of the invention is to overcome the technical disadvantages that existing water hammer can not prevent and receive, solve the problem of revolving at present and opening safety check reply water hammer from principle and structure, provide a kind of rational in infrastructure and water hammer self balancing of scientific in principle to revolve and open safety check.
To achieve these goals, the technological scheme that the present invention takes is:
A kind of water hammer self balancing is revolved and is opened safety check, it is characterized in that, comprise valve plate, the water hammer self balancing device with discharge orifice, described water hammer self balancing device offers discharge orifice on valve plate, be fixed with discharge orifice sealing plate fixed support in the surrounding of discharge orifice, sealing plate side be provided with the axis of guide, establish to help between fixed support and sealing plate and close spring, spring fitting is on the axis of guide, and opposite side is supported on fixed support.
Further, the size of described discharge orifice and valve design flow and pressure match are adjusted.
Further, help described in and close spring initial setting power and calculated by design conditions.
Beneficial effect of the present invention is:
Compared with prior art, one is establish discharge orifice, releases water hammer current in the present invention, and effectively prevention water hammer produces; Two is that spring promotes sealing plate design, and spring setting damping force, effectively absorbs water hammer.Its novel structure, safe and reliable, there is outstanding protecting water hammer function, wide accommodation.
Embodiment
A kind of water hammer self balancing is revolved and is opened safety check, it is characterized in that, comprise valve plate, the water hammer self balancing device with discharge orifice, described water hammer self balancing device offers discharge orifice on valve plate, be fixed with discharge orifice sealing plate fixed support in the surrounding of discharge orifice, sealing plate side be provided with the axis of guide, establish to help between fixed support and sealing plate and close spring, spring fitting is on the axis of guide, and opposite side is supported on fixed support.
Further, the size of described discharge orifice and valve design flow and pressure match are adjusted.
Further, help described in and close spring initial setting power and calculated by design conditions.
The water hammer self balancing that the present invention relates to is revolved and is opened safety check, when safety check cuts out in operating mode process, valve plate falls to sealing surface under waterpower and Action of Gravity Field, medium is blocked gradually in dropping process, reduce velocity of medium, produce water hammer thereupon, when the water hammer produced is greater than the spring setting force of self balancing device, spring is compressed, and discharge orifice sealing plate is opened, and water hammer current are discharged by discharge orifice, reduce the generation of water hammer, meanwhile, spring has damping function to water attack current, eliminates the water hammer power that a part has been formed.Discharge flow, spring, water hammer power autobalance in the process, the generation of prevention and elimination water hammer and water hammer is carried out, continuously until setting pressure.Thus available protecting valve itself and water supply network.
