Abstract
A vacuum degree tester for measuring the vacuum degree of a product is composed of a vacuum meter, a cylindrical base with open lower end, release valve, and vacuumizing unit communicated with said base via a conic hole in which there is a seal.
Description
The present invention relates to a kind of vacuum degree measuring instrument, a kind of tester of testing the vacuum tightness of container that all kinds of needs vacuumize and vacuum interlayer of more specifically saying so.
For container and the vacuum interlayer that all kinds of needs vacuumize, the size of its vacuum tightness directly influences the performance of product.But have only the vacuum degree leak test instrument to seal the back now and check whether leak gas, can't know but this product vacuum tightness remains on what order of magnitude at product.And check out that after product seals gas leakage is late, because can't repair, can only regard waste disposal.To accomplish that for the object that canister, vacuum glass and solar water heater (flat type solar heat collector) etc. are evacuated product is qualified, only just can accomplish air tightly for a long time in that its vacuum tightness more than 24 hours is constant, can not measure it and still there is instrument at present.
At the problems referred to above, the purpose of this invention is to provide a kind of tester that vacuum tightness detects that before product seals, carries out, it can also detect the numerical value of the vacuum tightness that this product can reach and how long the numerical value of this vacuum tightness can keep.
To achieve these goals, vacuum degree measuring instrument of the present invention comprises vacuum meter, it is characterized in that it also comprise a lower ending opening cylinder base, be installed in air release and vacuum extractor on the base, vacuum extractor communicates with base by a taper hole, have a diameter to be slightly larger than the seal of taper hole small-bore in the taper hole, described vacuum meter is installed on the base.
Described vacuum extractor comprises orientation dish, compressor arm positioning disk, screw, the screw of the positioning tube that is connected with base, the web member that links to each other with vacuum pump, the compressor arm that compresses seal and location and driving compressor arm, has pore on directed dish, compressor arm positioning disk and the screw.
Described vacuum extractor is installed on the base by the pickup groove on the base.
Between described positioning tube and the exhaust tube web member seal gasket is arranged.
Also has a back-moving spring on the described compressor arm.
The present invention can carry out the vacuum tightness test before product seals, have only certified products just to seal, thereby guaranteed product quality; Utilize the present invention can also observe vacuum tightness ground the long period and keep situation; And can observe the numerical value of vacuum tightness very intuitively by vacuum meter, after having solved container and interlayer vacuum-pumping and sealing, spend one day or after several days, still whether vacuum and vacuum tightness remain on a great problem on what order of magnitude not know to be evacuated container and interlayer.
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 general structure synoptic diagram of the present invention.
Fig. 2 base vertical view of the present invention.
Wherein, 1 base; 2 seals; 3 directed dishes; 4 compressor arms; 5 compressor arm back-moving springs; 6 pores; 7 compressor arm positioning disks; 8 screws; 9 screws; 10 exhaust tube web members; 11 screw pores; 12 seal gaskets; 13 positioning tubes; 14 gas admittance valves; 15 vacuum meters; 16 taper holes; 17 positioning tube pickup grooves; 18 gas admittance valve Fixed Nuts; 19 vacuum meter Fixed Nuts.
As shown in Figure 1, base of the present invention 1 is positioned over opening 22 places that are evacuated container or interlayer, the paraffin with fusing around base seals, and fastens gas admittance valve 14.Open vacuum pump and bleed, the air in container or the interlayer is drawn out of by the pore on opening 22, taper hole 16, compressor arm positioning disk 7 and the screw 86,11, exhaust tube web member 10, and at this moment seal 2 is backed down under the air-flow effect.When vacuum tightness reaches regulation numerical value (this numerical value is directly shown by vacuum meter 15), vacuum pump stops to bleed, and seal 2 falls into taper hole 16 immediately and carries out self-styledly under self gravitation, and tightly inhaled in taper hole 16 under negative pressure.Taken out in container and the interlayer for gas is entered, the web member 10 of will bleeding is with after positioning tube 13 separates, and rotation screw 9 moves down it, promotes compressor arm 4 and also moves down, and seal 2 is compressed.Park after 24 hours observe vacuum meter 15 indicator whether also on former regulation numerical value, to judge whether gas leakage.If air tight this product that is is qualified, can vacuumizes and seal this container or interlayer.Detection finishes, and opens gas admittance valve 14, and gas enters container or interlayer, vacuum degree measuring instrument can be removed.
As shown in Figure 2, positioning tube 13 is installed on the base 1 by pickup groove 17; Gas admittance valve 14 and vacuum meter 15 also are fixed on base 1 by Fixed Nut 18 and Fixed Nut 19 respectively.
For sealing better, also has a seal gasket 12 between positioning tube and the exhaust tube web member; Also have back-moving spring 5 on the compressor arm 4, can after test finishes, make compressor arm 4 homings.
Utilize vacuum tightness to estimate instrument, can carry out the vacuum tightness test the object that the container that utilizes material such as metal material, glass, pottery, plastics, stone material and cement or interlayer etc. need vacuumize.Can directly vacuum degree measuring instrument base 1 be bonded in for the object that big plane is arranged and carry out vacuum tightness on the object that is evacuated and test.If it is very little or not have the plane desirable to be evacuated object, then the openend of base can be sealed with dull and stereotyped 20, and on base, open an aperture 21, by cross over pipe be evacuated object and join, the end that joins can be adorned a sucker, sucker is bonded in be evacuated on the object, carry out the vacuum tightness test, also can adorn a gluey object on the object being evacuated, then sucker be changed into hollow needle tubing, needle tubing be inserted gluey object carry out the vacuum tightness test.After test finished, certified products sealed, thereby have guaranteed product quality.
