Description
Technical Field
The utility model belongs to the technical field of backwashing filtration, and particularly relates to a horizontal backwashing device for an exhaust valve of a water delivery pipeline.
Background
With the rapid development of national economy and the rapid increase of water consumption, in order to meet the urban water demand and solve the problem of uneven water resource distribution, the development and construction of large-scale, long-distance and cross-basin water supply projects has become a reality of no competition. Long-distance water delivery projects are established between water sources and cities, the fluctuation change of pipelines is often large due to long water delivery distance, and if the pipelines are not exhausted smoothly, the pipelines are easy to explode, huge economic loss is caused, and the safe and stable operation of a water supply system is seriously influenced. The exhaust valve system of the same water conveying pipeline needs to be repaired and replaced in a large area every year, the operation and maintenance cost is increased, and great potential safety hazards are brought to the operation of the system. In order to ensure the water supply safety of water transfer engineering in water-deficient areas, the practical problems to be solved urgently are to be solved by researching the existing exhaust valve system for preventing blockage and corrosion, improving the operation safety of pipelines and reducing the operation cost, and the method has huge application potential and social value.
Foreign researches on the aspects of anti-blocking and rusting of the exhaust valve are mostly applied to exhaust valve structures with higher precision requirements of automobiles, airplanes and the like. In foreign countries, Lee et al have studied the relationship between the air intake and exhaust flow coefficient of an air valve and the pressure fluctuation of a pipeline, and found that the negative pressure in the pipeline can be effectively controlled by arranging the air valve at the hump of the pipeline and under the condition of a large inflow flow coefficient, but the positive pressure in the pipeline can be increased due to the large outflow flow coefficient. American scholars developed a water hammer-proof exhaust valve with a valve body and a valve cover, the valve cover is fixedly connected, a valve opening is arranged on the valve body, and a high-speed air inlet and outlet device is arranged in an inner cavity of the valve body. In addition, different material patents exist for the rust prevention of the coating, but the application of the coating in the blockage prevention of the pressure pipeline exhaust valve is not common.
Some scholars in China also have some research on materials, methods and structures for preventing the blockage of the exhaust valve. The utility model relates to a research on gas-liquid two-phase and air valves of a long-distance water pipeline system, which is invented by Hejian Yong et al, a Shiweir Touchi electromechanical engineering company Limited in Hubei province, applies for an invention patent named as 'a paint spray booth water supply self-suction device' in 2018, 11 and 16, and reduces the problems of sewage backflow phenomenon and water pump operation influence caused by leakage of a bottom valve of an exhaust valve by replacing the bottom valve with the self-suction device. Wuhan Dayu valve member company limited has applied for the utility model patent of "filter screen" in 2012 10 months 10 days, and this filter screen is used for discharge valve entry, prevents that discharge valve from blockking up, has not only satisfied filtration requirement and can bear the interior water pressure of pipeline simultaneously, and is less to the area influence of overflowing, and the grid plate face is arranged along medium flow direction simultaneously, has improved impact resistance. Hubei province Rui pei dao warm new discharge valve that leads to scientific and technological limited research and development on tile is through separating upper cover and lower cover to can open wholly, be convenient for change the damaged part of inside, avoid the waste of resource, the connection structure setting of sleeve pipe and blast pipe simultaneously can effectually prevent that external debris from blockking first through-hole and second through-hole, thereby the people's of being convenient for use.
Aiming at the blockage and corrosion of the exhaust valve of the water delivery pressure pipeline, large-area maintenance and replacement are needed every year, so that the operation and maintenance cost is increased, and great potential safety hazards are brought to the operation of a system. When filling water in the pressurized pipeline, a large amount of silt and large-particle-size impurities enter the pipeline along with water flow, when water runs in the pipeline, air can be separated out in the water due to pressure, temperature change and the like, at this time, the air needs to enter the exhaust through the exhaust valve, and the impurities enter the exhaust valve body along with the water flow to block and corrode the exhaust valve, so that the normal use of the exhaust valve and the normal running of the pipeline are influenced.
In conclusion, most of the domestic and foreign researches on the exhaust valve are directed at the structure and the material of the exhaust valve, but few researches on the blockage of the pressure pipeline exhaust valve are carried out, and the improvement on the existing exhaust valve is rare. Water transfer engineering pipeline section is in the water supply period, and the maintenance frequency that leads to because of debris jam in the discharge valve increases, consequently carries out local improvement to current discharge valve, and furthest's the interior debris of reduction discharge valve are piled up, reduce to lead to the discharge valve trouble because of debris jam, is the steady operation of engineering and awaits the solution urgently.

The working principle of the utility model is that when water flow is filtered by the filter element 4, a large amount of accumulated impurities cause the blockage of the filter hole 22 of the filter element 4, the air pressure balancing device 7 (which is a purchased part) is closed, the blow-down valve 18 is opened, the motor 12 is started to drive the cleaning brush 8 to clean the filter element 4, water flow enters the filter element 4 from the back washing cavity 17 to clean the impurities accumulated in the filter element 4, the cleaned sewage is discharged from the blow-off pipe 14, after the back washing is finished, the blow-down valve 18 in the blow-off pipe 14 is closed, the exhaust valve on the water outlet is opened, and the water flow in the pipeline normally flows.
In the filtering process, suspended matters and the like in raw water are intercepted and adsorbed by the filter element 4 and are continuously accumulated in the filter element 4, so that the pores of the filter element 4 are gradually blocked by dirt, a filter cake is formed on the surface of the filter element 4, and the loss of a filtering head is continuously increased. When a certain limit is reached, it is necessary to clean the filter cartridge 4 to restore the operating performance of the filter cartridge 4 and continue the operation. Along with the increase of head loss in the filtering process, the shearing force of water flow to the filth adsorbed on the surface of the filter element 4 becomes large, and some particles enter the lower part of the filter under the impact of the water flow, so that the content of suspended matters in water is increased continuously, and the water quality is deteriorated. When the impurities permeate the filter element 4, the filter element 4 loses its filtering effect. Therefore, to some extent, it is necessary to clean the filter element 4 in order to restore the dirt-receiving capacity of the filter element 4. Suspended matter in the sewage contains a large amount of organic matter, and long-term retention in the filter element 4 causes the accumulation and propagation of microbial bacteria therein, and anaerobic putrefaction occurs. Therefore, the filter element 4 needs to be cleaned periodically. Ensuring the normal operation of the exhaust valve and the water delivery pipeline.
