Description
The utility model relates to leak detector, relates in particular to the quick leak detector of radiator dry type.
Radiator must carry out the sealing property test, is the important indicator that water tank is guaranteed the quality.Every water tank is all observed by domestic water tank manufacturing plant with traditional inflation bowssening leakage situation, but it is very big that this order is examined the human factor influence of leaking hunting, the reliability of quality assurance is reduced, precision is not high, and every water tank needs use a large amount of electric heating drying after detection, consumes the more energy, also influences the presentation quality of water tank simultaneously, throughput rate is not high, so the utmost point need the change method leak hunting.
The purpose of this utility model provides the quick leak detector of a kind of radiator dry type.
Be illustrated below in conjunction with accompanying drawing.
Fig. 1 is the quick leak detector synoptic diagram of radiator dry type;
Fig. 2 is that pneumostop clamps the chock plug synoptic diagram.
Radiator dry-type leak hunting instrument, its pressure regulator valve 3 outlets and bi-bit bi-pass (normally closed) electricity Magnet valve 5,6 imports are joined, two-position two-way solenoid valve 5 or 6 and pressure sensor 7, bi-bit bi-pass Magnetic valve (often opening) 8, differential pressure pick-up 9 and join with the snap joint 10 or 11 of check valve, Two-position two-way solenoid valve 6 or 5 and two-position two-way solenoid valve 8, differential pressure pick-up 9 and band check valve Snap joint 11 or 10 join. Said pressure regulator valve 3 imports and pressure regulator valve 4 imports are joined, Pressure regulator valve 4 outlet through two-position three way magnetic valve 13 with the snap joint 14 of check valve, 15 and Pneumostop clamps chock plug 16,17 and joins, pneumostop clamp chock plug 16 with check valve Snap joint 10 is joined, and pneumostop clamps chock plug 17 and snap joint 11 phases with check valve Connect. Pneumostop clamps chock plug 16 and joins with no leakage standard water tank 18, and pneumostop clamps Chock plug 17 joins with water tank 19 to be measured. No leakage standard water tank and water tank to be measured are same models The water tank of same volume. At the disqualification rate that is caused by leakage＜1%.
Pneumostop clamps chock plug and has air rammer 25, cylinder 24, establishes in the middle of the air rammer Air rammer pull bar 28 is arranged, and is gas tube in the middle of the air rammer pull bar, and an end is provided with the water tank inflation Joint 21 tightens up nut 23, handle 20, and air rammer off-centre is provided with pneumatic pinch joint 22 Hes Pneumatic gas tube also communicates with cylinder, and air rammer and cylinder inner wall are provided with seal 29, cylinder The center, top is provided with circular hole, joins with the air rammer pull bar outside, is provided with each other seal 26, Air rammer pull bar outside cover has rubber stopper 27, and the air rammer pull bar other end is provided with rubber stopper Fixture.
The utility model when work, draw back normally close valve 2 after, pressure is that the steady pressure gas of 0.5～0.6Mpa flows into the leak detector pipeline from source of the gas 1.At first open valve 13, make through pressure regulator valve 4 and pressure stability and control pneumostop clamping chock plug 16,17 respectively, make water tank 18,19 when inflation, obtain effective seal at the gas of 0.3MPa.Then, open valve 5,6, make through pressure regulator valve 3 and pressure stability and inflate to water tank 18,19 at the gas of 0.11MPa.Then, shut-off valve 5 and 6, because valve 8 is in normally open, then the air pressure of water tank 18,19 is identical, the output of differential pressure pick-up no signal.During detection, shut-off valve 8 does not have pressure reduction as two water tanks, shows that then these two water tanks do not have leakage phenomenon and take place; If any pressure difference signal output, then showing has leakage phenomenon to take place, and can make right judgement as long as changing 1 standard water tank compares this moment.
Because 5,6,8,13 be solenoid valve, and pressure transducer can provide the gas pressure value of measuring pipeline at any time, so whole measuring process very easily realizes robotization.
When pneumostop clamps chock plug work, hand-held handle 20, make rubber stopper 27 insert the import of water tank 18 or 19, when from the gas of valve 13 in joint 22 enters cylinder 24, this Pneumatic pressure is enough to make piston 25 drive pitch braces 28 to move to left, thereby make rubber stopper 27 become adjacent circumferential expansion, to realize the purpose of sealing clamping because of being subjected to axial compression.Gas from valve 5 or 6 is then inflated to water tank through the gas-filled tube of joint 21 and pitch brace 28.After measuring end, shut-off valve 13 makes the gas that enters in the cylinder 24 drain into atmosphere through joint 22 and valve 13, at this moment, the restoring force that pneumostop clamps chock plug 16 or 17 makes piston 25, pull bar 28 and rubber stopper 27 return to virgin state, and then rubber stopper 27 is promptly thrown off with the import from water tank 18 or 19.
This leak detector is based on the draught head principle and comes measured automobiles tank seal performance.When a leak free water tank and gas circuit, inflation back and the source of the gas cut-out that product water tank to be detected places same pressure.If the product water tank does not have leakage, then do not have pressure reduction between the two and exist; If the product water tank has leakage, then there is pressure reduction to exist between the two, can accurately judge leakage situation by differential pressure gauge, as exceed permissible value, be to qualified.
The quick leak detector of radiator dry type has fundamentally overcome the defective that the wet type method of leaking hunting exists, and it has not only improved reliability, precision and presentation quality, has saved a large amount of electric energy and expensive; And measure rapidly, easily be automated monitoring, help boosting productivity.
