Compressed-air liquid lifting device with counterweight steering valve

Abstract

The invention discloses a compressed-air liquid lifting device with a counterweight steering valve. A control mechanism is arranged on a conveying trough cover (2) of a conveying trough (1), and a compressed air inlet (14), an air inlet channel (9), an air passage (15) and a mounting hole are formed in the conveying trough cover (2) of the conveying trough (1). The compressed air inlet communicates with the mounting hole through the air passage, and the valve seat (21) of the control mechanism is positioned at the upper end of the conveying trough cover (2). A valve pocket (18) is arranged inthe mounting hole of the conveying trough cover, and a gate valve (12) and an air passage steering valve (16) are arranged in the valve pocket. The air passage steering valve is positioned under the gate valve and is connected through a valve rod, and the space between the valve rod and the air passage steering valve, the gate valve and the valve pocket forms a chamber (17). A compressed air channel (11) is arranged on the air passage steering valve, a positioning plate (23) and a weighted lever (19) are connected on the valve rod at the lower part of the air passage steering valve, and a floater (20) is connected on the weighted lever. The compressed-air liquid lifting device has the characteristics of realizing automatic operation, having safe and reliable performances, reducing the costof use, saving energy, reducing consumption, being convenient in maintenance.

Description

technical field [0001] The invention belongs to the technical field of air-pressed liquid lifter (pneumatic pump), and mainly relates to an air-pressed liquid lifter equipped with a counterweight steering valve. It has the function of automatically conveying the liquid in the tank container and exhausting it. Background technique [0002] Existing wind-driven pumps are mainly based on the wind-driven turbine type, which is mainly composed of pump outer body, wind wheel, water wheel, main shaft and other components. When working, the wind wheel is blown by compressed air, and the wind wheel drives the water wheel to rotate through the main shaft to realize the functions of conveying liquid and exhausting air. Due to the disadvantages of many rotating parts, easy wear and tear of parts, high noise, high requirements for sediment content and low service life, the pneumatic pump of this structure will increase the user's use cost and reduce maintenance costs. bring some diffic...

Problems solved by technology

Due to the disadvantages of many rotating parts, easy wear and tear of parts, high noise, high requirements for sediment content and low service life, the pneumatic pump of this structure will increase the user's use cost and reduce maintenance costs. bring some difficulties

Moreover, it cannot automatically stop working in an anhydrous state, which not only increases energy consumption, but also causes overheating, so it is not suitable for use in places with high safety performance requirements (such as mines, etc.)
