Abstract
The present invention relates to a kind of manometer checker, particularly make, a kind of portable pressure checker is provided in field-checking to oil, chemical industry, thermal technology, pressure (differential pressure) instrument.
It forms one by gas tank, inflator, reduction valve, hand behaviour bar, bleed pressure table, input pressure table.Verification is easy, and is reliable and stable, all adopts the universal standard parts of existing instrument in the device, and long service life all is equipped with locking mechanism in two hands behaviour bars, and output is stable, saves time, laborsaving, real in making things convenient for the comparatively desirable pressure validator of staff.
Description
The present invention relates to a kind of pressure gauge tester, particularly be convenient to field-checking, a kind of portable pressure checker is provided oil, chemical industry, thermal technology, pressure (differential pressure) instrument.
Have verification now, still do not have a kind of pressure checking device of industrial practicality, the checker of more unmatchful on-the-spot pressure (differential pressure) instrument oil, chemical industry, thermal technology, pressure (differential pressure) instrument.The staff very needs to be with inflator (air bag), field wirings such as three-way connection, master gauge inexpediently.When verification, still need usually and want two people's close fit, wayward, fluctuated by correction power definite value, often the time is long, efficient is low for instrument of verification, and error is bigger, is difficult for verification and goes out smart higher instrument.When particularly adopting U-tube manometer, just more bad operation, if careless slightly, mercury solution is gone out outside the pipe in the U-tube manometer, overflows on ground, has polluted environment, particularly the staff is brought the mercury evil.
Task of the present invention provides a kind of portable pressure checker, and the staff can only use a people, the free verification that realizes easily on-the-spot tensimeter and differential pressure gauge.
The present invention is assembled into one inflator, reduction valve, gas tank, tensimeter and output interface, carry light, when verification, wiring is simple, when the staff begins in verification, shakes crank lightly, after will being full of gas to gas tank, in whole checking procedure, do not need manually to inflate again when needing several instrument of continuous verification (if, still only need shake crank gently) to the gas tank tonifying Qi.When verification, the staff only need stir hand behaviour bar, changes each point, can stably provide set value signal.
Verification of the present invention is easy, speed is fast, time is short, reliable and stable, all adopt the universal standard parts that have instrument now, long service life in the device, really for making things convenient for the staff to reduce labor intensity, increase work efficiency, reduce the check meter error, improve a kind of comparatively desirable pressure validator of instrument check technical ability.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a scheme of erection of the present invention.
Fig. 3 is a working panel arrangenent diagram of the present invention.
Below with reference to accompanying drawing the present invention is illustrated.
In the accompanying drawing 1: 1, gas tank; 2, rocking bar; 3, transmission gear; 4, bent axle; 5, inflator; 6, reverse checkvalve; 7, output interface; 8, delivery gauge; 9, scale panel; 10, hand behaviour bar; 11, bleed pressure table; 12, lever; 13, cam; 14, roller; 15, reduction valve; 16, source of the gas pipeline; 17, output pipe.
In the accompanying drawing 2: 18, casing; 19, panel; 20, intermediate plate; 21, base plate.
In the accompanying drawing 3: 7, output interface; 8, delivery gauge; 9, scale panel; 10, hand behaviour bar; 11, bleed pressure table; 22, locking mechanism.
When the staff uses when of the present invention, as long as carry the scene easily, with master gauge with by the school tensimeter, be connected on output interface (7) with φ 6 emulsion tubes and get final product verification.When if no gas or gas are not enough in the gas tank, as long as shake rocking bar (2) gently, through transmission gear (3), bent axle (4), driving piston inflator provided (5) inflates, through reverse checkvalve (6), to gas tank (1) inflation, cut down (15) air feed to decompression, show it by bleed pressure table (11).
The beginning verification, as long as the staff stirs the hand behaviour bar (10) on the panel (19), drive cam (13), roller (14), lever (12), changed the spring displacement on reduction valve top, the output that makes it reduction valve (15) is by corresponding by correction power instrument requirement proof test value, the pointwise verification, method is easy.The present invention grasps bar (10) at hand and is provided with locking mechanism (22) again, so the checkpoint definite value is fast, steady, and keeps constant, has alleviated staff's labour intensity.
The present invention forms output system by reduction valve (15), lever (12), cam (13), roller (14), hand behaviour's bar (10), scale panel (9), and the scale good linearity, output is stable, and delivery gauge only for the reference of output indicating value, is not made standard scale.If to field instrument zero point and range check, output interface (7-1) can be blocked, (7-2) connects calibrated meter, and the indicating value of delivery gauge then can be represented by the pressure indicating value of school instrument.
If delivery gauge is selected for use when precision is higher makes standard scale, then directly can not connect master gauge separately in addition to by the manometric verification in school.
