Abstract
The utility model provides a plug-in balance flow meter which comprises a lead pressure pipe, a lead pressure pipe test head, a three-valve manifold, a differential pressure transmitter and an intelligent secondary meter. The lead pressure pipe test head is a multihole disc restricting element provided with nine function holes which are all through holes, wherein one function hole is arranged in the middle, the other eight function holes are respectively distributed around the centered function hole, the bore diameter of the centered function is 10-15 millimeters, and the bore diameter of the other eight function holes is 4-8 millimeters. A ball valve is connected between the multihole disc restricting element and the three-valve manifold, the ball valve is connected with the three-valve manifold through a flange on an upper side of the ball valve, and a short pipe is connected with the flange to connect and fix the ball valve and the multihole disc restricting element on a lower side of the ball valve. The three-valve manifold is connected with the differential pressure transmitter, and the intelligent secondary meter is connected with the differential pressure transmitter. The plug-in balance flow meter greatly saves steps and time of installation and dissembling, and simultaneously achieves non-cutoff installation.
Description
Technical field
The utility model relates to a kind of flowmeter, particularly discloses a kind of plug-in type balanced flow meter, is applicable to the rate of flow of fluid of measuring all gases, steam, liquid and other medium.
Background technology
Traditional differential pressure flowmeter has its inherent shortcoming, when loading and unloading, will stop, and therefore possibly cause economic loss.In practical application, because the restriction of concrete operating mode, and the crushing of orifice plate is big, energy consumption is high, range ratio is little, precision is low, straight length requires high reason, causes measuring very inaccurate.
Summary of the invention
The purpose of the utility model is to overcome the defective that exists in the prior art, provides that a kind of crushing is little, precision is high, range ratio is big, the plug-in type balanced flow meter of and can continue to flow loading and unloading low to the straight length requirement.
The utility model is achieved in that a kind of plug-in type balanced flow meter; Comprise pressure guiding pipe, pressure guiding pipe gauge head, three valve groups, differential pressure transmitter and intelligent secondary table; It is characterized in that: described pressure guiding pipe gauge head is the porous disc restricting element, and described porous disc restricting element is provided with 9 function holes, and described 9 function holes are through hole; Wherein 1 function hole is placed in the middle the setting; All the other 8 function holes are distributed on around the function hole placed in the middle, and aperture, 1 function hole placed in the middle is 10～15mm, and aperture, 8 function holes is 4～8mm around all the other.Be connected in series ball valve between porous disc restricting element and three valve groups, the upside of ball valve is connected ball valve by flange with three valve groups, and the ball valve downside is connected ball valve by the short tube joint flange and is fixing with the porous disc restricting element.Three valve groups link to each other with differential pressure transmitter, and intelligent secondary table links to each other with differential pressure transmitter.
The beneficial effect of the utility model is: plug-in type balanced flow meter is compared with the conventional balanced flowmeter; After the utility model inserts tested pipeline with the porous disc restricting element; The porous disc restricting element is connected with ball valve and fixing by the short tube flange; Save the step and the time of installation and removal greatly, realized the installation that continues to flow simultaneously.Because the porous disc restricting element is made up of a plurality of functions hole, can the balance flow field, the reduction vortex vibration significantly improves flowing field stability, so plug-in type balanced flow meter reduces the requirement of straight length greatly.Again because the utility model is a differential-pressure instrumentation; Irrelevant with external shock; The vortex shedding flow meter of comparing can be measured the vibrations fluid, not influenced by outside electromagnetic interference, and the electromagnetic flowmeter of comparing can be surveyed the electromagnetic interference (EMI) medium; Because plug-in type balanced flow meter restricting element both sides symmetry fully, so it can measure bidirectional flow again.
The measuring accuracy of the utility model is 5～10 times of conventional throttle device, and hydrodynamic noise is reduced to 1/15, and the permanent compression loss is about 1/3; Pressure recovers fast 2 times; Minimum straight length can be as small as 0.5D, does not have movable parts, installation and very easy to use simple; Can save big straight length, significantly reduce the required energy consumption of fluid operation.
