An anti-suckback adjustable pressure bubbler

Abstract

The invention relates to an anti-reverse suction type pressure-adjustable bubbler. The anti-reverse suction type pressure-adjustable bubbler comprises a cylinder body, an air exhaust vertical pipe, a receiving bottle, a pressurizing sleeve pipe and a pressure adjusting rod, wherein the air exhaust vertical pipe is fixedly arranged in the middle part of the cylinder body; the receiving bottle is connected with the lower part of the cylinder boy in a sealing way; the pressurizing sleeve pipe consists of an upper isolation cavity and a lower isolation cavity; a spring is arranged in the upper cavity, and the lower cavity sleeves the air exhaust vertical pipe; the pressure adjusting rod is abutted against the spring, and penetrates through a screw cover which is arranged at the top part of the cylinder body. Compared with the prior art, the anti-reverse suction type pressure-adjustable bubbler has the advantages that the air pressure can be effectively adjusted and controlled, the reverse suction of air is prevented, the environment-friendly and non-pollution effects are realized, and the like.

Description

technical field [0001] The invention relates to the field of gas pressure control, in particular to an anti-suckback adjustable pressure bubbler. Background technique [0002] The bubbler is an experimental device often used in factories and laboratories. It can be used in systems that require a certain positive pressure to promote the reaction; but because of its bubbling effect, it can make the entire reaction system in a safe environment. Work under gas pressure. It is used as a protective device for a closed gas system. If the airtight container is filled with too much gas, the gas can be discharged through the bubbler to protect the device and the safety of the experimenter; at the same time, by observing the bubbles in the bubbler Size, to estimate the size of the gas flow, so as to control the gas generating device, adjust the size of the gas flow, and improve the efficiency of gas use; the addition of liquid in the bubbler can also prevent the gas from sucking back,...

AI Technical Summary

Problems solved by technology

However, the existing bubbler devices are relatively simple, and most of them use mercury seals. Mercury poses a huge threat to people and the environment. It can only control a single gas pressure, and cannot achieve multi-level regulation of pressure. ; At the same time, it cannot control the anti-suck back very well. If the pressure of the device inside the device decreases, the liquid in the bubbler will be directly sucked back into the device, causing pollution damage to the device and causing certain economic losses.

[0003] Chinese patent CN205253157U discloses an anti-suckback bubbler. An air outlet pipe is processed on the side wall of the upper bottle body, an air guide pipe is processed on the outer bottom, and a ball holder connected to the air guide pipe is processed on the inner bottom. Steel balls are placed, the top of the upper bottle is provided with a cork, the side wall of the lower bottle is processed with an air intake pipe, the top of the lower bottle is provided with an upper bottle, and the air guide pipe extends into the lower bottle, depending on the steel The gravity of the ball prevents sucking back, but the pressure inside the bubbler cannot be adjusted
