Sliding-block-type liquid level metering device

Abstract

The invention discloses a sliding-block-type liquid level metering device.The sliding-block-type liquid level metering device comprises an L-shaped barrel with openings in the two ends, a floating barrel arranged in the barrel, a directional pulley fixed to the opening in one end of the barrel, a sluice valve arranged at the opening in the other end of the barrel and a sliding block.The floating barrel is connected with the sliding block through a nylon rope, and the nylon rope is wound around the directional pulley; liquid level scales are arranged at the portion, close to the sliding block, outside the barrel.The sliding-block-type liquid level metering device is reasonable in design and accurate in liquid level displaying, and has the advantages that liquid level displaying is not disturbed by impurities, observing blind zones of a liquid level meter are avoided, and cleaning is avoided; the problems that a traditional reinjection-tank liquid level meter is inconvenient to use, and potential safety hazards exist are thoroughly solved, and the operating efficiency of a reinjection system is greatly improved.

Description

technical field [0001] The invention relates to a liquid level metering device, in particular to a slider type liquid level metering device. Background technique [0002] The liquid level gauge is mainly used to measure the level of the liquid medium in the container, which can be applied in many fields. Most of the existing liquid level gauges are traditional magnetic float level gauges. When measuring the water level in a certain tank, the magnetic float is turned over by the change of the liquid level height to display the change of the liquid level in the tank. [0003] Taking the formation water sewage tank as an example, because the formation water (the sewage brought out by the production of natural gas) contains more impurities, it is very easy to cause the float of the liquid level gauge to get stuck and cannot be turned over, so that the magnetic float is always at a false liquid level. Change again, thus losing the liquid level display effect. At the same time, ...

Problems solved by technology

[0003] Taking the formation water sewage tank as an example, because the formation water (the sewage brought out by the production of natural gas) contains more impurities, it is very easy to cause the float of the liquid level gauge to get stuck and cannot be turned over, so that the magnetic float is always at a false liquid level. Change again, thus losing the liquid level display effect

At the same time, it is easy to cause the magnetic pole degaussing of the display of the liquid level control system, etc., forming a false liquid level and causing a safety hazard
