Description
Technical field
The utility model relates to a kind of technical field of pressure monitoring of low pressure pipeline of refining oil combustion furnace, is specifically related to a kind of low pressure refinery gas or the U-shaped pressure gauge monitoring device of gas pipe line.
Background technique
Coal gas is called the new lover of industrial fuel because the advantage such as low stain, high heat in its combustion process is slowly replacing coal; In oil refining extractive process, coal gas is directly delivered to combustion furnace by pipeline, need in combustion to ensure that coal gas conveying air pressure is in safety value, because the air pressure of coal gas conveying is only slightly larger than barometric pressure, so common manometric sensitivity is difficult to meet the needs to the monitoring of gas pipe internal air pressure in gas firing process, the recovery channel of refinery gas is low pressure pipeline equally in addition, also there is this problem.
Model utility content
In order to solve foregoing, a kind of barometric surveying equipment for detecting gas supply intraductal atmospheric pressure value being provided, devising the U-shaped pressure gauge of a kind of gas pipe line.
Concrete technology contents of the present utility model is:
A kind of low pressure refinery gas or the U-shaped pressure gauge monitoring device of gas pipe line, comprise U-tube, base plate, calibrated scale, inductor, alarm, it is characterized in that: U-tube is fixedly connected on base plate, calibrated scale correspondence is arranged in the middle part of U-tube; U-tube inside is provided with clear water, and wherein one end of U-shaped pipe is connected on low pressure refinery gas or gas pipe line by flexible pipe, and the other end tubular body is equipped with inductive probe, and described inductive probe is positioned at a certain scale value of the corresponding calibrated scale of ullage;
Inductor should be connected on alarm by wire pair.
The scale value of calibrated scale therefrom first marks successively to both sides, and U-tube is transparent tube body, and in pipe, the liquid level of water and calibrated scale zero graduation line are in same level.
Base plate upper end is provided with hook.
Dangerous scale value on the corresponding calibrated scale of inductive probe.
beneficial effect
Utilize law of connected vessels, by air pressure difference value trickle in low pressure refinery gas or gas pipe by the level change concrete manifestation in U-tube out, be convenient to the monitoring to intraductal atmospheric pressure value; Liquid level is provided with the inductive probe of corresponding dangerous air pressure, and when air pressure becomes greatly to dangerous values, liquid level rises to inductive probe, and inductor controls alarm buzzer and sends information warning, is convenient to people's Timeliness coverage potential safety hazard, improves the Security of producing.
