Description
Technical field
The present invention relates to a kind of leak test plant, more particularly, it relates to a kind of inhalator jar high-voltage leakage detector.
Background technology
At industrial circle, owing to being packaged with high pressure gas in inhalator jar, therefore the requirement of inhalator jar bottle to sealing is higher, in order to improve quality and the use safety of product, the defects such as (comprising the leakage of liquids and gases) that must ensure that inhalator jar does not leak, but, in the manufacturing process of inhalator jar, due to machinery and equipment, the impact of material or the factor such as artificial, inevitably there is the situation of leakage, therefore the leak detection of inhalator jar bottle is absolutely necessary link, no problem to ensure the leak tightness of bottle, in order to avoid cause safety misadventure because bottle leaks.
At present, common test method is be immersed in water after being sealed by the inhalator jar being filled with high pressure gas mostly, observes and whether has bubble generation.Produce bubble then to illustrate that inhalator jar exists and leak the phenomenon of tank, this water being also we commonly use detects the method for leaking, but water detects that to leak accuracy of detection not high, and naked-eye observation difficulty of whether leaking hunting is excessive.
And existing employing vacuum leak detection method detects the equipment of inhalator jar or other Packaging Bottle, first pallet is utilized to be sent in detection cylinder by inhalator jar or Packaging Bottle by a jacking system, be evacuated in detection cylinder again, and high pressure air is poured in inhalator jar, pressure sensor is utilized to detect the pressure detected in cylinder, if the force value detected this inhalator jar or Packaging Bottle in the pressure domain of walker set are acceptable product, otherwise be nonconformity, such as application number utilizes this principle exactly for the Packaging Bottle leak tester described in 201110461363.1, and for example application number is a kind of inhalator jar leak tester mentioned in 201220236480.8.
Adopt in prior art vacuum leak detection method carry out to inhalator jar leak hunting the equipment that detects and the above-mentioned application number mentioned be 201220236480.8 a kind of inhalator jar leak tester to enter at tray lift inhalator jar and detect the up-down mode of cylinder and usually adopt pneumatic/hydraulic to be elevated, or the rotating disc type Packaging Bottle leak tester that the type of drive mode of movement such as application number of employing gear driven rotating disk is 201210297054.X and the gear turntable mode of movement that a kind of packing container leak tester that application number is 201320596679.6 is mentioned, no matter be there is fugitiveness when pneumatic/hydraulic is elevated or gear turntable mode of movement all there is bull ladle bottling or inhalator jar, hydraulic/pneumatic lifting existing defects in continuity, and gear turntable mode of movement transmission gear easily weares and teares, service life is shorter, and in the lifting course of conveying of inhalator jar or Packaging Bottle, safety method is not set, once inhalator jar or Packaging Bottle are placed with deviation (not in the central area of pallet), extrude mutually with detection cylinder in lifting course of conveying, although safety method can be arranged on equipment but can cause damage to detection cylinder after all,
Next is the Packaging Bottle leak tester described in 20111046136.1 at application number, enter in the device of leak detection chamber in Packaging Bottle, Packaging Bottle is fixed and is separated with leak detection chamber by the inside and outside separating device of bottle, inside and outside separating device comprises bottle sealing circle and Packaging Bottle lift system, Packaging Bottle lift system comprises cylinder, ring-type mounting blocks, recoil spring, expansion set and circular cone, cylinder lift piston rod, piston rod drives valve and circular cone upwards to promote, in the uphill process of circular cone, the outside face of circular cone just can slide along the inside face of expansion set, thus expansion set is strutted, like this, above-mentioned expansion set is stretched in the bottleneck of Packaging Bottle by elasticity trim ring, play effect that is fixing and Sealed packing bottle, and application number for a kind of packing container leak tester described in 201320596679.6 adopt equally application number be mention in 20111046136.1 inside and outside separating device, and set-up mode speed under the effect of cylinder that this kind of fixed form exists expansion set and circular cone struts to fix Packaging Bottle, because the characteristic pull rate of cylinder is very fast, expansion set fast speed opens and easily impacts damage to Packaging Bottle bottleneck, wearing and tearing for expansion set are also larger, crucial can have influence on subsequent packet in the breakage of Packaging Bottle bottleneck and to bottle the accuracy of detection of leaking hunting.
