Gas-liquid two-fluid through-flow coupling adjusting device

Abstract

The invention discloses a gas-liquid two-fluid through-flow coupling adjusting device. The adjusting device comprises a valve body, an adjusting cap, a spring, a valve core, an air cavity cover and anair pressure plate, wherein an upper inner screw through hole which is in threaded connection with the adjusting cap is formed in the upper surface of the valve body, a lower inner screw through holewhich is in threaded connection with the air cavity cover is formed in the lower surface of the valve body, and an air inlet hole is formed in the middle of the air cavity cover; the valve body is internally provided with a liquid inlet cavity, a liquid outlet cavity, an upper through hole, a circular control hole, an air pressure adjusting cavity and a lower through hole; the valve core comprises an upper cylindrical section, a conical section and a lower cylindrical section, and the conical section is narrowed from top to bottom; and the upper end and the lower end of the spring abut against the upper surface of the adjusting cap and the upper surface of the upper cylindrical section respectively, the lower end surface of the lower cylindrical section is vertically connected with the upper surface of the air pressure plate, and the outer cylindrical surface of the air pressure plate is attached to the inner cylindrical surface of the air pressure adjusting cavity. The adjusting device is applied to a low-pressure low-flow system and has the advantages of being low in device cost, small in required installation space, timely in response and capable of making sure the continuous and stable gas-liquid flux flow matching effect.

Description

technical field [0001] The invention specifically relates to a gas-liquid two-fluid flow coupling regulating device. Background technique [0002] Gas-liquid two-fluid flow coupling technology is widely used in many fields of industry, especially in the occasions related to two-fluid atomization and spraying. In industrial applications, it can be used for spray humidification, desulfurization and dust removal, dry fog dust suppression, and cooling of plate pipes. Wait. [0003] In different engineering application fields, there are different requirements for the size and velocity of the droplets, so it is necessary to control the ratio of gas and liquid, and to adjust the amount of liquid spraying when the gas pressure fluctuates, so as to achieve the best gas-liquid ratio , to achieve optimal control of droplet size and velocity. [0004] The existing gas-liquid two-fluid regulating flow coupling technology is mainly realized by electrically adjusting the opening of the c...
