Today, we introduce a patent for the invention of a national invention - silicon brass lead-free smart water meter. The patent was applied by Shanghai Tianshen Copper Group Lead-free Smart Water Meter Co., Ltd. and was authorized to be announced on June 1, 2018.
DescriptionThe invention relates to the field of water meters, in particular to a silicon brass lead-free smart water meter.
Background of the inventionA water meter is a device that measures the amount of water used. Commonly used in the user side of the tap water, the degree is used to calculate the basis of the water fee. Water meters are usually measured in cubic feet (ft3) or cubic meters (m3). Most of the water meter shells used in the market are made of lead-containing metal, which has low mechanical strength and contains lead in the water flowing through it. Long-term drinking is harmful to human health, and the copying of these water meter data requires a lot of manpower and Time, work efficiency is low.
Summary of the inventionIt is an object of the present invention to provide a silicon brass lead-free smart water meter to solve the problems set forth in the above background art.
The figure shows the structure of the invention
In order to achieve the above object, the present invention provides the following technical solution: a silicon brass lead-free intelligent water meter, including a waterproof incubator, a wireless router, a mounting block, a water inlet, a back cover, a cover, a cover, and a photoelectric water meter movement. , wireless controller, water meter housing, water outlet, sealing ring, installation box, net, fan body, mounting plate and motor. The water meter housing is provided with a water inlet at one end and a water outlet at the other end. The top surface and the bottom surface of the nozzle are symmetrically arranged with a mounting block, and the water outlet of the water meter housing is provided with a gasket, and a photoelectric water meter movement is arranged at a central portion of the water meter housing, and a surface cover is arranged directly above the photoelectric water meter movement. The cover is circular, the cover is fixed at a circular through hole at the top of the water meter housing, and a cover is arranged directly above the cover, and the cover is connected with the top of the water meter housing; the bottom of the water meter housing is provided with a sewage outlet for discharging A sealing ring is arranged at the entrance of the mouth, and a rear cover is arranged at the bottom of the sewage outlet. The rear cover is connected with the bottom of the water meter housing, and the water meter housing is fixed inside the waterproof incubator, and the waterproof incubator is protected by The material is made, and the outer wall and the inner wall of the waterproof incubator are coated with a layer of environmental protection waterproof coating. The middle part of the inner wall of the waterproof incubator is provided with a wireless router, and the central part of the inner wall of the waterproof incubator is provided with a wireless controller; A mounting box is arranged on one side of the inner wall of the bottom plate of the box, and the mounting box is located under the wireless controller. The top of the mounting box is provided with a square through hole, and the square through hole is provided with a partition net. The partition net is made of stainless steel material, directly under the net The mounting plate is arranged, the mounting plate is laterally disposed, and the outer wall of the mounting plate is connected with the inner wall of the mounting box; the middle of the inner wall of the bottom plate of the mounting box is provided with a motor, the motor is located below the mounting plate, and the rotating shaft of the motor passes through the mounting plate and the fan body. The rotating shaft is connected, the fan body is fixed at a middle position of the top surface of the mounting plate, the fan body is located between the partition net and the mounting plate, and the vertical central axis of the fan body and the vertical central axis of the net mesh are coincident; the processing method of the water meter housing is : Preheating the power frequency induction furnace, using cathode copper and charcoal, feeding the power frequency induction furnace to make charcoal coverage On the cathode copper; then gradually heating the power frequency induction furnace, melting the cathode copper and then adding a copper-silicon intermediate alloy, wherein the mass percentage of silicon is 20-40%, melting and fully stirring and adding zero zinc, fully stirring to make the alloy melt mix evenly Then add P-Cu alloy for deoxidation, add refining agent and stir; then fully stir, then sample and analyze, adjust the composition until the above casting performance requirements are met; then let stand, slag, 1000~1100 °C heat preservation, voltage 210V, After standing for 20 minutes, the impurities were precipitated or floated to purify the alloy melt; finally, the temperature was raised to 1150 to 1160 ° C and poured out.
As a further aspect of the invention, the water meter housing is made of a lead-free environmentally friendly silicon brass alloy material. The lead-free environmentally-friendly silicon brass alloy material has the following components by weight: copper 61-64 parts, silicon 0.5-0.7 parts, aluminum 0.5-0.7 parts, lead 0.1- 0.1 parts, iron 0.1-1.15 parts, tin 0.2 to 0.3 parts, nickel 0.2 to 0.3 parts, boron 0.0008-0.0012 parts, phosphorus 0.008- 0.01 parts, manganese 0.008-0.01 parts, sulfur 0.008-0.01 parts, cadmium 0.008-0.01 parts, 铋0.008-0.01 parts, 锑0.01- 0.02 parts, magnesium 0.002-0.005 parts, arsenic 0.008-0.01 parts, cobalt 0.001-0.002 parts, chromium 0.002-0.005 parts.
Compared with the prior art, the invention has the beneficial effects of fixing and positioning the water meter by using the mounting fixing block to avoid the occurrence of misalignment, and expanding the volume of the water meter housing by using the back cover, reducing the water gauge pressure and improving The water meter is stable, and the back cover is used to store impurities entering the watch. The wireless router and the wireless controller can remotely perform meter reading, reduce labor loss, improve work efficiency, and use a waterproof incubator to prevent the water meter from freezing in winter, using a fan. The body heats the water meter in summer, and avoids the outside sewage to penetrate into the water meter to reduce its service life. The water meter shell is prepared by using lead-free environmentally-friendly silicon brass alloy material to avoid the harm of lead water to the human body and improve the safety of water quality. The invention improves the mechanical performance, and the invention can accurately position the water meter, and saves time and labor by using the remote meter reading intelligent operation, thereby improving the safety performance and the service life of the water meter.
