Bar, the push rod connects a rocking bar, and the glass jar outer wall is provided with a through hole, and the rocking bar is located at glass jar through the through hole
Outer wall；
Alcoholic solution is full of in the glass jar；
By the way that by film silk, under alcohol-pickled, the film silk full of air can bubbling；Air pressure is relevant with aperture by force, and aperture is got over
Greatly, the air pressure that bubbling needs is smaller；Aperture is smaller, and the air pressure that bubbling needs is bigger.
The present invention closes air motor when finding that bubble appears in the top of push rod, and then shaking rocking bar makes on push rod
Rise, the film for having leak source silk is raised to be higher by by push rod to be easy to observe and mark.The present invention in alcoholic solution due to operating so not
Burning can be caused using electro-motor, air motor can only be used to realize.
A compressed gas cylinder is provided with the box body, the compressed gas cylinder is provided with a gas outlet, and the gas outlet is provided with first
Film silk, second branch are not detected on branch outlet and the second branch outlet, the first branch outlet alignment let off roll
The film of detection silk on outlet alignment wind-up roll.
The present invention makes the air pressure at two ends equal by two ends ventilation, is not in the situation about losing on the way of pressure.
The let off roll is provided with first pressure sensor, and the wind-up roll is provided with second pressure sensor, described the
One pressure sensor is connected with the second pressure sensor with a microprocessor system, and the microprocessor system connects
An electronic display is connect, the electronic display is fixed on the outer wall of the glass jar.
The present invention can be detected by pressure sensor to the pressure of let off roll and wind-up roll, once both pressure
Value changes, and illustrates the aligning direction generation deviation or compressed gas cylinder of the first branch outlet and the second branch outlet and has gas leakage
Situation.
The present invention triggers potential safety hazard by defining that the volume of alcoholic solution can prevent alcoholic solution excessive.
As a kind of scheme, the push rod bottom is provided with a hinge wheel, and the hinge wheel is connected with the rocking bar, when not detecting
During leak source, the push rod is in horizontal positioned, when detecting leak source, and rotating rocker makes hinge wheel drive push rod in vertical placement.
A runner is provided with the top of the push rod.
The present invention can facilitate push rod rise not cause damage to film silk by runner.
As a kind of scheme, the push rod is that a rubber pulley is cased with the top of a metallic rod, the push rod
Originally post to prevent from being excessively sharp at the top of metallic rod by rubber pulley and make film silk damaged.
The box body is a sealing box body body, provided with push rod outlet at the top of the box body, the shape of the push rod outlet with
The cross section of the push rod is consistent, and top and the push rod outlet of the rubber pulley are maintained at same straight line.
Brief description of the drawings
Fig. 1 does not detect structural representation during leak source for the present invention；
Fig. 2 detects structural representation during leak source for the present invention.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction, which is specifically illustrating, is expanded on further the present invention.
Film is not detected provided with winding in reference picture 1, Fig. 2, the bubble pressure leak detecting of film silk, including a glass jar 12, glass jar
The let off roll 1 of silk and winding have detected the wind-up roll 2 of film silk, and let off roll 1 is each attached to the bottom of glass jar with wind-up roll 2；Put
Winding up roller 1 is connected by the first chain 6 with the first air motor 3, and wind-up roll is connected by the second chain with the second air motor 4；
A push rod 5 is provided between let off roll 1 and wind-up roll 2, push rod connects a rocking bar 11, and glass jar outer wall is provided with a through hole, and rocking bar is worn
