Abstract
The utility model which relates to a pressure obtaining device of the pressure difference of the liquid level used in measuring the water levels of boiler steam headers and the liquid levels of other vessels solves the problem that the pressure difference of the vapor-liquid level in the boiler steam headers or other vessels is not certain at a certain time. By adopting the technical project that gaseous medium is used to heat an altitudinal tube 7 and preserve the heat of the altitudinal tube 7, the utility model keeps the temperature in the altitudinal tube 7 and the interior liquid in uniform distribution and in a certain value in different environmental temperatures and heat dissipating conditions, which leads the pressure produced by the altitudinal tube 7 and the interior liquid column to be a certain value. The utility model can accurately provide the liquid level pressure difference of water levels of boiler steam headers and other vessels, improve the safety and economy of device running and has good economic and social benefits.
Description
Technical solutions of the utility model relate to a kind of constructing technology that is used to measure the liquid level differential pressure pressure obtaning device of boiler drum level and other tank fill level.
Normal operation in order to guarantee to produce in daily productive life, ensure the needs of people's lives, needing to install on boiler-steam dome and other container be liquid level differential pressure pressure obtaning device, so that measure differential pressure between vapour (gas) side and the water side, compensate afterwards indicated water level and liquid level.
Technical problem to be solved in the utility model: under varying environment temperature and radiating condition, keep level tube 7 and internal liquid uniformity of temperature profile and be a certain determined value, so that guarantee that the pressure of level tube 7 its inner fluid columns generations is a certain determined value.
The technical scheme of the technical matters that the utility model solves is such:
Vapour (gas) the side level tube 7 outside insulating tubes 8 of installing, insulating tube 8 is installed in measures tube 3 inside, and top communicates with measuring tube 3 inside, and the bottom is communicated with discharging tube 6; Insulating tube 8 interior liquid are discharged by discharging tube 6 under gravity and pressure effect during equipment fortune property, the medium that charges between vapour (gas) side level tube 7 and the insulating tube 8 is vapour (gas) body medium and surrounds vapour (gas) side level tube 7 fully that the medium that charges between vapour (gas) side level tube 7 and the insulating tube 8 in the steam water-level differential pressure pressure obtaning device is a saturated vapour; Level tube 7 all adopts vapour (gas) body medium to surround, level tube 7 and internal liquid thereof are heated insulation, temperature is approaching or equal vapour (gas) body medium temperature, the pressure that level tube 7 its inner fluid columns produce under the certain pressure is certain value like this, according to the differential pressure between the vapour of measuring (gas) side pressure guiding pipe 4 and the liquid side pressure guiding pipe 5, compensate, just can accurately calculate the liquid level of boiler drum level or other container with vapour (gas) the body medium temperature in boiler-steam dome or other container.Overcome existing apparatus level tube temperature uncertain, measure the inaccurate phenomenon of indication, can improve security, the economy of equipment operation, have good economic benefit and social benefit.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a cut-open view of the present utility model
Fig. 2 is a vertical view of the present utility model
Fig. 3 is vapour (gas) side level tube 7 top umbrella shape funnel cutaway view Amplified images
Vapour (gas) side-draw pressure pipe 1, liquid side-draw pressure pipe 2, discharging tube 6 are pipe, measuring tube 3 outward appearances is cylindrical structural, vapour (gas) side skirt 4 is, liquid side pressure guiding pipe 5 is pipe, and vapour (gas) side level tube 7 tops are that umbrella shape funnel, bottom are pipe, and insulating tube 8 is a pipe; Can select other materials such as steel for use according to environment for use.Vapour (gas) side-draw pressure pipe 1 is communicated with measurement tube 3 tops, and vapour (gas) side pressure guiding pipe 4 is communicated with vapour (gas) side level tube 7 bottoms; Measuring tube 3 bottoms is communicated with liquid side-draw pressure pipe 2 and liquid side pressure guiding pipe 5 respectively; Vapour (gas) side pressure guiding pipe 4, liquid side pressure guiding pipe 5 center lines are at grade, and are and vertical with the center line of measuring tube 3.Vapour (gas) side level tube 7 is installed in the external diameter of the umbrella shape funnel outward flange diameter on insulating tube 8 inside, its top greater than insulating tube 8, and insulating tube 8 is installed in and measures that tube 3 inside, top communicate with measurement tube 3 inside, the bottom is communicated with discharging tube 6.Vapour (gas) side level tube 7 and insulating tube 8 coincide with the center line of measuring tube 3.
This device passes through vapour (gas) side-draw pressure pipe 1 and liquid side-draw pressure pipe 2, is communicated with vapour (gas) side and the liquid side of boiler-steam dome or other container respectively during fitting operation, and the center line of measuring tube 3 must be perpendicular with surface level; The pipe fitting that is connected with discharging tube 6 bottoms should guarantee under differential pressure and action of gravity, the liquid in the insulating tube 8 is in time discharged not hydrops; Tackle this device during installation and suitably be incubated processing.Under varying environment temperature and the radiating condition, the differential pressure of vapour (gas) side and liquid side with vapour (gas) the body medium temperature compensation in boiler-steam dome or other container after, just can accurately reflect boiler drum level or other tank fill level.
