Abstract
The invention relates to a water level display device for a deaerator. The water level display device is connected with a deaerator barrel and comprises a magnetism rolling board water level gauge, a pressure sensor and a liquid level transmitter, wherein the magnetism rolling board water level gauge, the pressure sensor and the liquid level transmitter are connected with a steam-water communication pipe of the deaerator barrel. The magnetism rolling board water level gauge is connected to the outlet end of the steam-water communication pipe, and the pressure sensor and the liquid level transmitter are connected to the steam-water communication pipe through tee joints respectively. Compared with the prior art, the high-temperature-resistant magnetism rolling board water level gauge is mounted according to the principle of communicating vessels, an operator can visually see the liquid level of the deaerator on site in polling, the steam-water communication pipe can be flushed through sewage disposal in operation at ordinary times, the water level display device is safe, reliable and visual, liquid levels are identical under same pressure in the deaerator, and therefore operation is convenient, comparison is convenient, modifying cost is low, and the water level display device is simple and practicable.
Description
Technical field
The present invention relates to a kind of level displaying device, especially relate to a kind of oxygen-eliminating device level displaying device.
Background technology
At present, oxygen-eliminating device liquid level is that the pressure differential produced by height of water level shows oxygen-eliminating device liquid level to transmitter, because carbonated drink communicating pipe bore own is less, block once there be foreign material and just easily cause artifical water height, maintenance does not at ordinary times have blowoff valve to rinse, just in case operative employee encounters this situation cannot judge in oxygen-eliminating device, water level has how many actually, bring great potential safety hazard to safe operation of the boiler.
Chinese patent CN203573174U discloses a kind of deaerator level automatic control system, and condenser, the first condensate pump, shaft sealing cooler, main inlet control valve, the first heat exchanger and oxygen-eliminating device are connected in series successively; Second condensate pump is in parallel with the first condensate pump, and secondary variable valve is in parallel with main inlet control valve; Also by being with the pipeline of flow valve to be connected between shaft sealing cooler with condenser; Deaerator level automatic control system also comprises controller, and flow valve, the first condensate pump, the second condensate pump, main inlet control valve and secondary variable valve are all controlled by controller, but this kind of control system does not have the function of blowdown.
Summary of the invention
Object of the present invention is exactly provide a kind of safe and reliable, oxygen-eliminating device level displaying device intuitively to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of oxygen-eliminating device level displaying device, be connected with oxygen-eliminating device cylindrical shell, this device comprises and is connected to magnetic turnover panel limnimeter, pressure transducer and fluid level transmitter with the carbonated drink communicating pipe of oxygen-eliminating device cylindrical shell, described magnetic turnover panel limnimeter is connected to the endpiece of carbonated drink communicating pipe, and described pressure transducer and fluid level transmitter are connected on carbonated drink communicating pipe through threeway respectively.
Be interconnected through communicating pipe between described pressure transducer and fluid level transmitter.
The lower end of described magnetic turnover panel limnimeter is also connected with blowoff valve.
Described magnetic turnover panel limnimeter is connected with carbonated drink communicating pipe through threeway.
Described carbonated drink communicating pipe is also connected with ball valve.
Described oxygen-eliminating device cylindrical shell is also connected with gas outlet, this gas outlet is provided with electric-powered air release valve and discharge line valve.
Compared with prior art, the present invention utilizes the principle of linker to fill a set of resistant to elevated temperatures magnetic turnover panel tank gage, operative employee can see oxygen-eliminating device liquid level at the scene intuitively when patrolling and examining, also can carry out blowdown when running at ordinary times and rinse carbonated drink connecting leg, safe and reliable, directly perceived, in oxygen-eliminating device, same pressure liquid level is identical everywhere, therefore easy to operate, comparison is convenient, and improvement cost is low, simple.
