Abstract
The utility model relates to a pressure tapping device for measuring water level of boiler stream drum and liquid level and differential pressure of other containers and conducting a series of processing of an elevation pipe, the differential pressure fluctuation is small when the pressure drops suddenly in the boiler stream drum or other containers, certain differential pressure and temperature signals determined are output under a certain liquid level, and the accurate liquid level in the boiler stream drum or other containers is calculated by using the pressure in the boiler stream drum or other containers; the utility model improves the safety and economy of the equipment in operation 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, and especially the pressure error is very little when pressure jump.
At present, known liquid level differential pressure pressure obtaning device has single-compartment balance container, vapour (gas) side stopple coupon, equalizing reservoir, level tube, vapour (gas) side-draw pressure pipe connect successively, vapour (gas) side stopple coupon, liquid side-draw pressure pipe are communicated with vapour (gas) side and the liquid side of boiler-steam dome or other container respectively, full of liquid in the level tube forms differential pressure and output with liquid side medium; But fluid temperature skewness in equalizing reservoir, the level tube, upper temp is the liquid medium saturation temperature, produces the carbonated drink transpiration during abrupt pressure reduction, the differential pressure instability that fluid column forms in the level tube, the output differential pressure fluctuation is big; Temperature of lower is higher than environment tens degree, and the upper and lower temperature difference is big, and non-linear along the short transverse temperature variation, can not carry out fine compensation.
In order under various operating modes, accurately to measure the liquid level in boiler-steam dome or other container, the utility model provides a kind of liquid level differential pressure pressure obtaning device, and not only differential pressure fluctuation is little when static energy differential pressure that output is determined according to liquid level but also the abrupt pressure reduction in boiler-steam dome or other container.
The technical scheme of the technical matters that the utility model solves is such: vapour (gas) side stopple coupon, liquid side-draw pressure pipe inclination certain angle, thief hole side height, be communicated with vapour (gas) side and the liquid side of boiler-steam dome or other container respectively, perhaps be communicated with boiler-steam dome or vapour (gas) side and the liquid side of other container vapour (gas) water side communicating pipe outward respectively, intercepting basin extend into drum or other internal tank, there is vapour (gas) water side should extend into vapour (gas) water side communicating pipe inside during communicating pipe, be convenient to collect condensation water, reach and stablize liquid level, intercepting basin, vapour (gas) side stopple coupon level connects, then successively with level tube, vapour (gas) side-draw pressure pipe connects, angle is greater than 90 degree between vapour (gas) side stopple coupon and the level tube, in the level tube outside or vapour (gas) side stopple coupon, vapour (gas) side pressure guiding pipe and level tube adjacent are provided with temperature element, and the external application material different with level tube, can make the level tube uniformity of temperature profile, layer insulation do not laid in vapour (gas) side stopple coupon interlude outside, and nature or pressure are cooled off during work; During this liquid level differential pressure pressure obtaning device operate as normal, fluid temperature does not produce the carbonated drink transpiration well below corresponding pressure saturation temperature down during abrupt pressure reduction in the level tube, and the differential pressure that fluid column forms in the level tube is stable, and it is very little to export differential pressure fluctuation; Level tube is upper and lower to have a narrow range of temperature, and is linear along the short transverse temperature variation, can carry out fine compensation according to measuring temperature; According to liquid level differential pressure pressure obtaning device defeated go out differential pressure, temperature signal, utilize the pressure in boiler-steam dome or other containers can accurately extrapolate liquid level.
The beneficial effects of the utility model are that it is very little to export differential pressure fluctuation during abrupt pressure reduction, exports differential pressure, the temperature signal of determining under certain liquid level, utilizes pressure, change in boiler-steam dome or other container can extrapolate liquid level accurately, and simple in structure; Can improve security, the economy of main equipment operation, have good economic benefit and social benefit.
