Description
Technical field
The utility model relates to device for pressure measurement, specifically is a kind of U-shaped pipe measuring cell.
Background technology
During the pressure of the fluid in people need know pipeline or container (liquid or gas), all to use device for pressure measurement, U-shaped pipe measuring cell is exactly a kind of measurement gas pressure measuring cell of (comprise negative pressure and differential pressure, also be used to measure the liquid of low-pressure sometimes) that is used for of using always.This measuring cell is to utilize its interior work fluid column weight and balanced each other by measuring pressure, thereby represents a kind of pressure instrumentation of tested pressure value with liquid-column height.Compare with other device for pressure measurement, the pressure measurement of U-shaped pipe in respect of simple in structure, the errors of principles is little (accuracy is higher), advantage such as with low cost; Its measurement range also can be regulated by the liquid of changing the different densities in the U-shaped pipe.Except that on producing, being widely used, especially under lab, use U-shaped pipe measuring cell especially frequently, also adapt to different measurement ranges through the hydraulic fluid of changing in the U-shaped pipe commonly used.When measuring malleation or negative pressure, except that the manometric pressure measurement end of U-shaped pipe is not have the leak condition ground UNICOM the manometric other end of this U-shaped pipe and atmosphere UNICOM (this instructions calls this end " breathing end ") with the pipeline at the gas place of its pressure to be measured or container.Problem is, and is when measuring the pressure of malleation, less than normal or when existing surge pressure, the liquid in the U-shaped pipe will overflow from breathing end-the often generation especially under lab of this phenomenon when the top pressure value of pre-estimating.This is for the situation of dress water in the U-shaped pipe, and problem is also little, and people do down cleaning and just finish.And for the situation that mercury is housed in the U-shaped pipe, situation has been far from good with regard to some.Because mercury is all-pervasive after letting out ground, recovery is got up very difficult, has caused very big waste (laboratory that has will slattern several kilograms of mercurys in a year).More seriously, mercury is poisonous material, when with infiltering the seam or other holes, the seam in vaporized mercury after, with seriously threatening operating personnel's health and even life, also can cause very big harm to environment simultaneously.
The utility model content
The technical problems to be solved in the utility model is when measuring malleation, to prevent to overflow arbitrarily, also can the fluid that overflow be reclaimed fully from the fluid that the manometric breathing end of U-shaped pipe overflows.
The scheme that solves this technical problem is, adopt a kind of with the anti-U-shaped pipe measuring cell of letting out container, this measuring cell is being the U-shaped pipe that hydraulic fluid is housed in it, is used for gaging pressure certainly, and this U-shaped pipe has the pressure measurement end and breathes end (generally being filled with the hydraulic fluid of half height, i.e. the zero-bit of scale).The pipeline or the container at same fluid (as said in the background technology, this fluid is the liquid under gas or the low pressure situation) place with its pressure to be measured of this pressure measurement end do not have leak condition ground UNICOM.Its improvements are, breathing end wherein is connected with an anti-container of letting out with atmosphere UNICOM, and the port of this breathing end is this anti-letting out in the container.That is to say that the manometric breathing end of this programme U-shaped pipe is not directly with atmosphere UNICOM, but directly with an anti-container UNICOM of letting out, prevent letting out container and atmosphere UNICOM by this again.It will be apparent to those skilled in that, allow and prevent letting out container and atmosphere UNICOM, promptly can be the vessel port of just utilizing this container; Also can be to block under the situation of vessel port, on container stopper or nearly vessel port place leave a pneumostome, perhaps adorn one in addition and allow its respiratory siphon inner and atmosphere UNICOM at this vessel port place.
After scheme disclosed out, those skilled in the art just can be clear that, after the liquid in the U-shaped pipe takes place was breathed the situation that end overflows from it, the problem that overflows arbitrarily took place this liquid that can not that overflows, and can only stay in the spill-proof container.Obviously, this spill-proof container also is simultaneously the device of collecting, reclaiming.This is for the situation that is filled with mercury in the U-shaped pipe, said waste mercury in the background technology just will not take place and the harm operating personnel are healthy and problem that environment is impacted.In addition, be the situation of other liquid (as alcohol etc.) for what adorn in the U-shaped pipe, reduction of expenditure is arranged too and reduce the beneficial effect of environmental pollution.
Below in conjunction with accompanying drawing the utility model is further described.

Embodiment
A kind of this measuring cell is the U-shaped pipe 1 that hydraulic fluid 2 is housed in it, is used for gaging pressure with the anti-U-shaped pipe measuring cell of letting out container, and this U-shaped pipe 1 has pressure measurement end 11 and breathes end 12.This pressure measurement end 11 does not have leak condition ground UNICOM with the pipeline 6 or the container at the fluid place of its pressure to be measured, identical with the mode of all manometric UNICOMs of U-shaped pipe, this pressure measurement end 11 is to have extended to always and be connected on the pipeline 6 at its pressure place to be measured or the container by connecting flexible pipe (being generally the top-quality rubber pipe); This breathing end 12 is connected with an anti-container 3 of letting out with atmosphere UNICOM, and 12 port one 2 ' prevent letting out in the container 3 at this is held in this breathings.Obviously, this breathings end 12 of the port one 2 of this breathing end ' can be itself prolongs and advances to prevent to let out the interior ports of container 3; The port that also can be this breathing end 12 by connecting flexible pipe and one end anti-let out extension that extension 123 UNICOMs container 3 in form breathing end port one 2 ' (this extension 123 is exactly to hold an end of 12 UNICOMs by being connected the breathing of flexible pipe and U-shaped pipe at an anti-end of letting out outside the container 3).Back one mode or structure are all more convenient aspect making and installation, all adopt the latter in following each example.
A last paragragh is following each routine summation, and the content identical with this summation do not given unnecessary details in following each example.
Embodiment 1 (with reference to figure 1):
This example is a kind of instantiation on summation part basis, and same section is not given unnecessary details.This routine extension 123 is with anti-to let out container 3 be to connect firmly to holistic, and the bottom of letting out container 3 is prevented in (extending into) anti-these breathing end 12 port ones 2 ' sensings of letting out in the container 3.Allow this prevent letting out this anti-respiratory siphon 4 at container 3 vessel port places of letting out that is mounted in of container 3 and atmosphere UNICOM.More specifically say and be, should anti-let out container 3 tops a vessel port was arranged, respiratory siphon 4 is to intert to be installed in this anti-letting out on the container 3 at a container stopper 5 of this vessel port, one end of this respiratory siphon 4 anti-let out container 3 outside, an end anti-let out in the container 3 (obvious, need for certain, be connected as a whole admittedly without this container stopper) and can and should anti-let out container 3 this respiratory siphon 4 equally.
From realizing the purpose of design angle, more than disclose enough.But anti-let out that container 3 is done (waste material) too much, liquid 2 is from this breathings port one 2 ' be unlikely to again after releasing too quickly again along preventing that the respiratory siphon 4 of letting out container 3 splashes away simultaneously in order not cause.As improvement, be provided with one again and both can have prevented the structure that liquid 2 splashes away along respiratory siphon 4 again described respiratory " flow-disturbing " to this example.Concrete structure is, this respiratory siphon 4 is to intert with vertical state to be installed in this anti-container 3 tops of letting out at the container stopper 5 of this vessel port, and it is 90 ° bending that this respiratory siphon 4 has its angle at the anti-segment port of letting out in the container 3.Obviously, these 90 ° of values are not " mathematics " notion but engineering concept, are preferably less than 90 ° during actual bending.
Obviously, after the anti-liquid 2 of letting out splendid attire in the container 3 has certain amount, can be in any way, means or instrument take out them from anti-letting out the container 3.Convenient in order to take out them, as this example is further improved, a discharging tube 31 that is clogged its mouth of pipe by stopper 311 is set on the container 3 anti-letting out.Need to take out anti-ly when letting out the liquid 2 of splendid attire in the container 3, untie extension 123 outer ends and is connected the connection between the flexible pipe and removes this and prevent letting out container 3, pull up the stopper 311 that clogs discharging tube 31 mouths of pipe, outwards topple over its interior liquid 2 and get final product.
Embodiment 2 (with reference to figure 2):
This example be on summation part basis another kind of instantiation, simultaneously be again improvement (variation of a kind of concrete structure in other words conj.or perhaps), so the part partly identical with embodiment 1 with summation do not given unnecessary details with respect to embodiment 1.Different aspects are: this routine extension 123 is to separate two devices making with the anti-container 3 of letting out.The anti-container stopper 5 of letting out the vessel port place plug of container 3 of this example has two through holes, and a through hole passes by extension 123, and another allows this anti-respiratory siphon 4 of letting out container 3 pass.Usually, it is all the same with the U-shaped pipe with extension 123 that this prevents letting out container 3, and it makes material is glass.When anti-container 3 and the extension 123 let out is split up into after two devices make, just reduced they have been fired together trouble, yield rate also can improve greatly.
Embodiment 3 (with reference to figure 3):
This example be on summation part basis another instantiation, simultaneously be again variation, so the part partly identical with embodiment 2 with summation do not given unnecessary details with respect to embodiment 2.Different aspects are: the anti-container 3 of letting out of this example is not provided with discharging tube.When need take out anti-ly when letting out the liquid 2 of splendid attire in the container 3, extract earlier and anti-ly let out the container stopper 5 of container 3 and remove this and anti-ly let out container 3, then, this anti-container 3 of letting out that tilts allows the liquid 2 in it pour out from vessel port.
Obviously, this example is compared with embodiment 2, more is applicable to the anti-occasion that surface tension is little, container that receive this liquid 2 has enough big vessel port of letting out the liquid 2 in the container 3.
Embodiment 4 (with reference to figure 4,5):
This example be on summation part basis another instantiation, simultaneously be again variation, so the part partly identical with embodiment 3 with summation do not given unnecessary details with respect to embodiment 3.Different aspects are: this example anti-lets out the respiratory siphon that container 3 does not have to settle all to be had in above each example-corresponding, the through hole that its container stopper 5 also has only a breathing end 12 that allows U-shaped pipe 1 pass.And a diversion groove 33 is arranged at this anti-vessel port edge of letting out container 3.This diversion groove 33 degree of depth and length, with container stopper 5 stop up anti-let out the vessel port of container 3 after, still can form required respiration channel and be degree.
Obviously, more than in each example for the anti-set respiratory siphon 4 of container 3 or the purpose of respiration channel of letting out, all be in order to prevent that liquid 2 from spilling from anti-vessel port of letting out container 3 again.If the anti-container 3 of letting out is enough big or surely think that liquid 2 is not very big from the speed of the breathing port one 2 of U-shaped pipe 1 ' release, then as said in the scheme, " allowing and prevent letting out container 3 and atmosphere UNICOM, can be the vessel port of just utilizing this container ".
