This gas tightness detection device including air supply, logical air through tube and two parallelly connected branch roads that set up that the air supply communicates, is equipped with differential pressure sensor, one between two branch roads the end -to -end connection of branch road has standard substance, another the end -to -end connection of branch road has the test article, follows the direction of admitting air in the standard substance and is provided with a plurality of plastics siphunculuss, and the place mix of a plurality of plastics siphunculuss forms honeycomb stationary flow route together. Through setting up two parallelly connected branch roads, one sets up the test article on the road, and another is the setting standard article on the road, set up differential pressure sensor between two branch roads, through contrasting two atmospheric pressure difference on the road, measures the gas tightness circumstances of test article, through set up a plurality of plastics siphunculuss at the standard substance for atmospheric pressure in the standard substance can fast and stable, thereby makes the more accurate stability of testing result.
Description
Technical field
The utility model is related to air tightness detection equipment, more particularly to it is a kind of can fast and stable detection air pressure air-tightness inspection
Survey device.
Background technology
Because engine sump tank is in the fabrication process it is possible that many naked eyes trachoma, the micropore that cannot distinguish etc. lack
Fall into, it is therefore desirable to carry out air-tight test to engine sump tank, prior art is detected using artificial by the way of, general
In engine sump tank immersion water tank, engine sump tank is filled plus compressed air in water tank, by observing engine oil pan
Sheath gas bubble situation about emerging is present determining whether there is the situation of leakage, and this detection mode operation labour intensity is big, work effect
Rate is low, and is not easy to control using artificial its dynamics of hydraulic motor oil sump, and the quality of its detection is unstable；Also one kind side
Formula be with air pressure differential pressure contrast method detect engine sump tank whether reveal, but this detection method often due to contrast
Standard items interior air-flow is unstable, causes the result difference of same part repeated detection to exceed ± 10%, is unsatisfactory for client's
Technical requirements.
Utility model content
Be solve problem above, the utility model provide it is a kind of can fast and stable detect air pressure air-tightness detection device,
Fast and easy can be detected to gas tightness of engine oil pan using the device, and measurement data stabilization is accurate.
The technical solution adopted in the utility model is：It is a kind of can fast and stable detect air pressure air-tightness detection device, bag
Source of the gas, two branch roads for being arranged in parallel and being connected with source of the gas by tracheae, the adjusting air valve and air gauge being arranged on tracheae are included,
The end of one branch road is connected with standard items, and the end of another branch road is connected with test article, two branch roads
Between be provided with differential pressure pick-up, be equipped with air valve on two branch roads, it is characterised in that：Along airintake direction in the standard items
Some plastics siphunculus are provided with, the place mix of some plastics siphunculus forms cellular current stabilization path together.
Preferably, being connected with signal processor on the differential pressure pick-up, numeral is connected with the signal processor
Display and alarm.
The utility model obtain beneficial effect be：By setting two branch roads of parallel connection, test is set on a branch road
Product, set standard items on another branch road, differential pressure pick-up is set between two branch roads, by contrasting the air pressure on two branch roads
The poor airtight implementations to measure test article；Some plastics siphunculus are set by standard items so that the air pressure in standard items
Can fast and stable so that testing result more accurate stable.
Brief description of the drawings
Fig. 1 operation logic figures of the present utility model；
Fig. 2 is the structural representation of standard items；
Fig. 3 is the A-A sectional views of Fig. 2.
Specific embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, it is of the present utility model it is a kind of can fast and stable detect the air-tightness detection device of air pressure, including source of the gas
1st, two branch roads being arranged in parallel connected with source of the gas 1 by tracheae 11, source of the gas 1 respectively to two branch road gas transmissions, in two branch
Differential pressure pick-up 4 is provided between road, the pressure differential between two branch roads can accurately be reflected by differential pressure pick-up 4,
The end of one branch road is connected with test article 2 (test article is the motive oil sump for needing detection), another end of branch road
Standard items 3 are connected with, signal processor 5, the output end of signal processor 5 are connected with by holding wire on differential pressure pick-up 4
It is connected with digital display 6 and alarm 7.If test article 2 has trachoma or pore, air pressure difference can be produced on two branch roads,
Air pressure difference shows specific numeral after differential pressure pick-up 4 is processed through signal processor 5 by digital display 6, while
Alarm 7 is alarmed；If the air-tightness of test article 2 is good, on two branch roads air pressure can be produced equal, differential pressure pick-up 4 is not believed
Number output.
As Figure 2-3, the utility model is provided with some plastics siphunculus 31 (in figure in the standard items 3 along airintake direction
In standard items be provided with 14 plastics siphunculus), the path of some plastics siphunculus 31 be mutually combined formed together it is cellular
Current stabilization path, the air-flow that the cellular current stabilization path can quickly in temperature standard product 3 so that the data of duplicate measurements are more
Plus it is stable, the result for measuring is more accurate.
Operation principle of the present utility model is：First by connecting each pipeline and circuit, source of the gas 1 is opened, by air valve 9
With the output pressure that air gauge 8 adjusts source of the gas 1；After after the output pressure of source of the gas 1 stabilization, while opening the air valve on two branch roads
10, you can complete the detection to the air-tightness of test article 2.
