Boiler exhaust valve capable of reducing liquid sloshing by utilizing air elasticity

Abstract

The invention relates to the technical field of boiler exhaust valves, and discloses a boiler exhaust valve capable of reducing liquid sloshing by utilizing air elasticity. The boiler exhaust valve comprises a valve body, wherein a drain opening is formed in the top of the valve body, retaining blocks are fixedly connected to the interior of the valve body, a piston is movably connected to the surfaces of the retaining blocks, a blocking ball is fixedly connected to one sides, away from the retaining blocks, of the piston through a piston rod, the surface of the blocking ball is movably connected with a compression mechanism, the lower portion of the blocking ball is movably connected with a clamping mechanism, and the lower portion of the clamping mechanism is slidably connected with an inflow opening. According to the boiler exhaust valve, gas is discharged from an exhaust groove in the compression mechanism, at the same time, the condition of liquid oscillation inside the valve bodyis observed, the contact condition of air holes and the blocking ball is controlled by rotating a rotating rod, and the speed of the exhaust gas is indirectly controlled; after the part of air holesare blocked, the vapor outflow speed is slowed to cause the pressure inside the valve body to become large, and the oscillation liquid causes water molecules inside the valve body to be pressed underthe action of high pressure, so that the effect of eliminating the liquid oscillation is achieved.

Description

technical field [0001] The invention relates to the technical field of boiler exhaust valves, in particular to a boiler exhaust valve which utilizes air elasticity to reduce liquid turbulence. Background technique [0002] The exhaust valve is used to adjust the air retained in the pipeline system, and is widely used in engineering fields such as drainage, shipbuilding, and fluid transportation. The development of science and technology and the continuous deepening of engineering practice have improved people's awareness of exhaust valves, especially in boiler applications. [0003] The boiler exhaust valve is a valve used to discharge the air pockets in the boiler, eliminate air blockage, and prevent water hammer. Water hammer phenomenon: the water is heated and boiled, causing the boiler to vibrate violently and collide violently, causing damage to the boiler and causing hot water to flow. If it is not smooth, it will form an air blockage, which may cause the circulating ...

[0003] The boiler exhaust valve is a valve used to discharge the air pockets in the boiler, eliminate air blockage, and prevent water hammer. Water hammer phenomenon: the water is heated and boiled, causing the boiler to vibrate violently and collide violently, causing damage to the boiler and causing hot water to flow. If it is not smooth, it will form an air blockage, which may cause the circulating pump to suck and burn out, and if it is serious, the circulating pump will stop running, causing vaporization and explosion, endangering property and personal safety; although the existing exhaust valve can effectively prevent water hammer. However, it is neglected that when water flows in the exhaust valve, the impact on the valve body will cause the exhaust valve to vibrate, and this vibration is amplified by the continuously flowing gas, which will eventually cause the boiler to vibrate together, resulting in the phenomenon of neglecting the other; in addition, the existing The speed of the gas exhausted by the boiler exhaust valve depends entirely on the temperature of the boiler and the degree of water evaporation. There is no direct control function, which makes the exhaust process unable to be fully controlled independently and affects work efficiency. Therefore, a method that uses air elasticity to reduce Liquid turbulent boiler exhaust valve came into being
