It is stamped and formed out on 1 middle section position of stainless steel tube (being also not in the position of center, also close to any end) flat
Pipeline section 2；When production, first confirm that the leaked bubble of standard leak block to be made is chosen opposite with the great standard of diameter
Answer the capillary stainless steel tube of inner diameter size；Then capillary stainless steel tube is put on press machine fragment position flattening wherein；Then
Deformed capillary stainless steel tube one end is ventilated, the other end into the water and checks the bubbling quantity in the unit time；It is emitting
When bubble quantity quantity is excessive, then carries out punching press and be repeated several times to reach the bubbling quantity in the unit time of demand.
Standard tester 4 of the present invention includes that standard leak is inserted into pressure vessel 5 and position to be tested on pressure vessel 5
Block 3, the standard leak block 3 include capillary steel tube 1 and the pipeline section 2 for being located at the diminution of capillary steel tube middle section position upper channel.
Further, in order to design rationally, above-mentioned capillary steel tube is capillary stainless steel tube, and it is to pass through punching press that channel, which reduces,
Form flat pipeline section.
Further, above-mentioned pressure vessel can be the cylinder 5 of installation water filter filter core, by with entery and delivery port
503 stack shell 501 and cover 502 is constituted.Certain pressure vessel can also be the container of the carrying pressure of other purposes.
Standard leak block of the present invention, standard tester simple structure and reasonable design, are conducive to that standardized test volume is made
Tool, can be using in vitro detection, the detection of workshop machine table etc..
The production method of standard tester of the present invention, the standard tester 4 is including pressure vessel 5 and in pressure vessel 5
Standard leak block 3 is inserted into upper position to be tested；The standard leak block includes capillary steel tube 1 and is located in capillary steel tube
The pipeline section 2 that fragment position upper channel reduces；It first makes standard leak block 3: first confiring that the leaked gas of standard leak block to be made
Bubble is to choose the capillary stainless steel tube of corresponding inner diameter size with the great standard of diameter；Then capillary stainless steel tube is put into
Fragment position is flattened wherein on press machine；Then deformed capillary stainless steel tube one end is ventilated, the other end is into the water simultaneously
Check the bubbling quantity in the unit time；When bubbling quantity quantity is excessive, then carries out punching press and be repeated several times to reach demand
Bubbling quantity in unit time；Then position to be tested is being needed to punch in pressure vessel sample to be tested, it will be ready-made
The capillary stainless steel tube of standard leak amount is embedded to pressure vessel, and dispensing fixing seal is good, and after glue is dry, standard sample has been made
At.
The application method of standard tester of the present invention, the standard tester 4 is including pressure vessel 5 and in pressure vessel 5
Standard leak block 3 is inserted into upper position to be tested, and the standard leak block 3 includes capillary steel tube 1 and is located at capillary steel tube
The pipeline section 2 that middle section position upper channel reduces；In use, the standard tester 4 is installed to pressure vessel finished product sealing propertytest
In equipment 6, which has the special gas connecting with standard tester entery and delivery port
Body delivery outlet 7, the other end have be sealed and coated on pressure vessel finished product connecting pin to wrap body 8, pressure vessel finished product and pressure
Container structure is identical, including the cylinder that stack shell and cover are constituted, wraps the detector 9 that body 8 is connected with measurement special gas；Work as peace
After installing, inputting the quantitative special gas that once measures into pressure vessel from special gas delivery outlet, (special gas can
To be hydrogen etc.), the set time is stood, special gas amount be discharged is checked in wrapping the detector that body is connected, according to this
Special gas amount be discharged number, come judge the pressure vessel finished product leak-testing apparatus whether debug met detection pressure
The requirement of force container finished product needs to adjust the firm gas for inputting once measure less when measuring the more of special gas amount be discharged
Body, and when measuring the few of special gas amount be discharged, that is, need to increase the quantitative gas that input once measures.
The reason of standard tester progress board test obtained is that (i.e. batch is raw for pressure vessel and pressure vessel product
The product of production) structure is identical, the difference is that the stack shell and cover of pressure vessel product are consolidated to be tightened by sealing ring
It is fixed, and soldering is done in the junction of 5 stack shell of pressure vessel and cover, it is ensured that sealing, the ventable amount of such pressure vessel 5 are
For the mistake tolerance (bubbles volume) for being inserted in standard leak block 3 thereon, therefore, as long as the standard that test is mounted on pressure vessel 5
Leak the gas output (can measure by detector 9) or bubbles volume (can be surveyed into the water by a water pipe 10 out that block 3 exports
It is fixed), can know a gas output of the pressure vessel finished product leak-testing apparatus 6 on delivery outlet 7 whether standard, be otherwise
It needs to be adjusted, therefore standard tester obtained can carry out the cubing of board test.
Therefore, present invention has the advantage that
1, structure is simple, easy to process, cheap；
2, accuracy is high, and an entire plane-leakage is not easy to plug；
3, Stainless Steel Capillary steel pipe is not easy to get rusty, and is unlikely to deform blocking, long service life.
The foregoing is merely presently preferred embodiments of the present invention, all to accomplish variation and modification according to scope of the present invention patent
It should all belong to the scope of the present invention.
