Above -mentioned tap that makes an uproar falls, speed reduction pipeline section internal diameter on water flow direction is all crescent, has reduced the velocity of flow on the one hand, reduces the formation in torrent district, and on the other hand has increased water pressure. Meanwhile, the vortex baffle also can strengthen the vortex effect, restraines the torrent district and forms. Acceleration rate pipeline section internal diameter on water flow direction all reduces gradually, can reduce water pressure, improves the fluidic velocity of flow simultaneously.
Description
Technical field
This utility model relates to a kind of faucet, is specifically related to the faucet of the little low cost of manufacture of a kind of noise.
Background technology
Existing faucet, it is uneven that outlet water flows out stream, and it is big to go out to flow noise, rings bigger at student dormitory and collective field group photo.The main cause that noise produces is that external environment makes object shake, thus drives surrounding air resonance sounding.What faucet noise produced main reason is that, at water tap buckle, high speed water jet impact pipeline produces vibrations, the vibrations of metallic water pipe and then drive surrounding air resonance, produces sound wave and causes relatively loud noise.
Utility model content
Flowing out the uneven problem bigger with noise during water discharge of water faucet of stream to solve water in prior art, this utility model provides a kind of noise reduction faucet.
A kind of noise reduction faucet, including the deceleration pipeline section being sequentially connected with, L-shaped pipe section and speedup pipeline section.Deceleration pipeline section internal diameter in water (flow) direction is all gradually increased, and deceleration pipeline section connects water-supply-pipe, and the internal diameter of water-supply-pipe is less than the minimum diameter of deceleration pipeline section.Described pipe section is bent into by pipe, and the bending place of described pipe section is provided with multiple turbulent baffle, and each turbulent baffle stagger arrangement is arranged；Ball valve is installed in pipe section, described ball valve is provided with rotating handles.Speedup pipeline section internal diameter in water (flow) direction is all gradually reduced, and the opening of speedup pipeline section is outlet, and outlet is provided with drainage screen.
Preferably, the inwall of described pipe section scribbling noise reduction layer, described noise reduction layer is made up of elastomeric material.
This utility model compared with prior art, has the advantages that
According to Bernoulli equation:
In formula: Z represents the potential energy of fluid in faucet；P/ γ represents the energy having due to fluid pressure, and wherein γ=ρ g, γ are the severe of fluid media (medium)；u2/ 2g represents the energy that fluid has because of speed；Considering that faucet is horizontal pipeline, the most in the same horizontal line, therefore potential energy Z is negligible for outlet and water-supply-pipe.According to ignoring the Bernoulli equation after Z:
P/ γ and u2/ 2g adds up to certain value, meets preservation of energy.When fluid flows through noise reduction faucet, on the premise of flow is certain, pipe section is long-pending to be increased suddenly, will certainly reduce flow velocity u so that hydraulic pressure raises.Same, if caliber reduces suddenly, flow velocity will be made to increase, pressure reduces.
Above-mentioned a kind of noise reduction faucet, deceleration pipeline section internal diameter in water (flow) direction is gradually increased, and on the one hand reduces flow velocity, reduces the formation of turbulent area, on the other hand adds hydraulic pressure.Meanwhile, setting up multiple turbulent baffle in order to strengthen flow-disturbing effect in faucet, suppression turbulent area is formed.The inwall of pipe section scribbles noise reduction layer, can absorb the sound wave that fluid produces due to vibration.Speedup pipeline section internal diameter in water (flow) direction of noise reduction faucet is all gradually reduced, and can reduce hydraulic pressure, improve the flow velocity of fluid simultaneously.The water inlet of noise reduction faucet and outlet pressure differential are relatively big, and water outlet flow velocity is relatively big, and fluid can flow more smoothly in noise reduction faucet.Being additionally provided with drainage screen on outlet, drainage screen can make the ejection of uniform fluid flow.
Accompanying drawing explanation
Fig. 1 is the profile of a kind of noise reduction faucet.
1 water-supply-pipe；2 deceleration pipeline sections；3 ball valves；4 rotating handleses；5 turbulent baffles；6 speedup pipeline sections；7 drainage screens.
Detailed description of the invention
Below in conjunction with Fig. 1, this utility model is described in detail.
A kind of noise reduction faucet, including the deceleration pipeline section 2 being sequentially connected with, L-shaped pipe section and speedup pipeline section 6.Deceleration pipeline section 2 internal diameter in water (flow) direction is all gradually increased, and deceleration pipeline section 2 connects water-supply-pipe 1, and the internal diameter of water-supply-pipe 1 is less than the minimum diameter of deceleration pipeline section 2.Described pipe section is bent into by pipe, and the inwall of pipe section scribbles the noise reduction layer being made up of elastomeric material.The bending place of described pipe section is provided with multiple turbulent baffle 5, and each turbulent baffle 5 stagger arrangement is arranged；Ball valve 3 is installed in pipe section, described ball valve 3 is provided with rotating handles 4.Speedup pipeline section 6 internal diameter in water (flow) direction is all gradually reduced, and the opening of speedup pipeline section 6 is outlet, and outlet is provided with drainage screen 7.
According to Bernoulli equation:
In formula: Z represents the potential energy of fluid in faucet；P/ γ represents the energy having due to fluid pressure, and wherein γ=ρ g, γ are the severe of fluid media (medium)；u2/ 2g represents the energy that fluid has because of speed；Considering that faucet is horizontal pipeline, the most in the same horizontal line, therefore potential energy Z is negligible for outlet and water-supply-pipe 1.According to ignoring the Bernoulli equation after Z:
P/ γ and u2/ 2g adds up to certain value, meets preservation of energy.When fluid flows through noise reduction faucet, on the premise of flow is certain, pipe section is long-pending to be increased suddenly, will certainly reduce flow velocity u so that hydraulic pressure raises.Same, if caliber reduces suddenly, flow velocity will be made to increase, pressure reduces.
Above-mentioned a kind of noise reduction faucet, deceleration pipeline section 2 internal diameter in water (flow) direction is all gradually increased, and on the one hand reduces flow velocity, reduces the formation of turbulent area, on the other hand adds hydraulic pressure.Meanwhile, setting up multiple turbulent baffle 5 in order to strengthen flow-disturbing effect in faucet, suppression turbulent area is formed.The inwall of pipe section scribbles noise reduction layer, can absorb the sound wave that fluid produces due to vibration.Speedup pipeline section 6 internal diameter in water (flow) direction of noise reduction faucet is all gradually reduced, and can reduce hydraulic pressure, improve the flow velocity of fluid simultaneously.The water inlet of noise reduction faucet and outlet pressure differential are relatively big, and water outlet flow velocity is relatively big, and fluid can flow more smoothly in noise reduction faucet.
Certainly; described above is not to restriction of the present utility model; this utility model is also not limited to the example above, change that those skilled in the art are made in essential scope of the present utility model, retrofits, adds or replaces, and also should belong to protection domain of the present utility model.
