Abstract
The utility model discloses a leak detector for welding lines of compressor barrels. The leak detector comprises a support. The support is provided with an upper arm and a testing seat. The leak detector is characterized in that the upper arm is provided with a pressure air cylinder; the tip of a plunger of the pressure air cylinder is provided with a rubber compression block; the testing seat is provided with a lower seal seat; the center of the lower seal seat is provided with a testing air flue; the end face of the lower seal seat is provided with a seal groove; and an O-shaped seal ring is arranged in the seal groove. According to the leak detector disclosed by the utility model, two ways of compressed air are used, wherein one of the two ways of compressed air is used as power to drive the rubber compression block to be compressed with the O-shaped seal ring in the manner of matching, so that confined spaces are respectively formed at both ends of a welded accessory, such as a pipe orifice; the other way of compressed air is used as detection gas injected into the confined spaces, thus, whether the welding line leaks or not is directly observed. Testing is rapid and is low in cost. The whole detection process is simple, convenient and rapid. Only low-cost compressed air is consumed. The leak detector is suitable for detecting barrels one by one on a large scale.
Description
Technical field
The utility model is a kind of instrument that detects refrigerator, air conditioner compressed machine drum body weldquality, specifically, is a kind of compressor cylindrical shell weld seam leak detector.
Background technology
Refrigerator, air conditioner compressed machine drum body are welded with the suction mouth of pipe usually, and the detection method of welding back butt welded seam quality generally has two kinds.First kind is to use helium to detect, and this mode needs mass spectrometer to carry out the detection of amount of leakage, and the helium of consumes expensive is not suitable for the detection one by one of part in enormous quantities.Second kind is part to be immersed tank detect; Tank is immersed in complete machine sealing back check whether have bubble to overflow; Single cylinder part is not welded loam cake and lower cover owing to two ends; Be difficult to realize sealing detection, and need whole oven dry to do antirust processing after detecting, so method also is not suitable for doing the detection of cylinder part.
Summary of the invention
To the defective that prior art exists, the utility model proposes a kind of compressor cylindrical shell weld seam leak detector, can be fast and the impermeability of testing weld seam at an easy rate.
The technical scheme of the utility model is: a kind of compressor cylindrical shell weld seam leak detector, comprise support, and support is provided with upper arm and test bench; It is characterized in that: upper arm is equipped with the cylinder of exerting pressure; The exert pressure plunger termination of cylinder is provided with the rubber compact heap, and test bench is provided with bottom sealing socket, and the bottom sealing socket center is a testing air passage; The end face of bottom sealing socket is provided with seal groove, and seal groove is built-in with the O RunddichtringO.
The utility model uses two-way pressurized air, and first via pressurized air is as power, drives the rubber compact heap and cooperates with O type circle and compress, and making the accessory in the welding is mouth of pipe two ends formation seal cavity; The second road pressurized air injects seal cavity as detecting with gas, and whether directly observe weld seam has leakage, and test is quick and cheap.

Embodiment
Do further explain below in conjunction with embodiments of the invention and accompanying drawing thereof.
See a kind of compressor cylindrical shell weld seam leak detector shown in the drawings, support is provided with upper arm 2 and test bench 6, and upper arm 2 is equipped with the cylinder 1 of exerting pressure, and the plunger termination of the cylinder 1 of exerting pressure is provided with rubber compact heap 3.Test bench 6 is provided with bottom sealing socket 5, and bottom sealing socket 5 centers are testing air passage 9, and the end face of bottom sealing socket 5 is provided with seal groove 7, and seal groove 7 is built-in with O RunddichtringO 8.
The end face that bottom sealing socket 5 is provided with seal groove 7 is and the cylinder curved surface of tested cylindrical shell 4 inside surface same radius, sees Fig. 2 and Fig. 3, and bottom sealing socket vertically (being the Y of tested cylindrical shell 4) sectional view shows that end face projection line 11 is straight line; Fig. 4, Fig. 5 are the bottom sealing socket transverse cross-sectional view, show that end face projection line 11 is a circular arc line, and radius R is identical with tested cylindrical shell 4 inside surface radiuses, and the end face of tested cylindrical shell 4 inside surfaces and bottom sealing socket 5 can fit like a glove when test, guarantees that sealing effectiveness is good.The collar wall of the seal groove 7 of bottom sealing socket 5 has a leaning angle ɑ, and getting leaning angle ɑ is that 5 degree are better, and it is the space that has distortion to tie up when guaranteeing O RunddichtringO 8 pressurizeds that leaning angle ɑ is set.
Compressor cylindrical shell 4 to be measured is put to test bench 6, confirmed that the tested mouth of pipe 10 weld seams of cylindrical shell 4 get in the scope of O type circle, cylindrical shell 4 inside surfaces compress the end face that O type circle 8 is pressed close to bottom sealing socket 5.Open the air inlet switch (not shown) of the cylinder 1 of exerting pressure; First via pressurized air gets into the cylinder 1 of exerting pressure, and the plunger end head drives rubber compact heap 3 by moving shown in the arrow F among the figure downwards, is pressed on the tested mouth of pipe; Cylindrical shell 4 compresses O type circle 8, and the tested mouth of pipe and bottom sealing socket 5 form seal cavity.Open sealing detection air intake opening switch (not shown), the testing air passage 9 from bottom sealing socket 5 gets in the tested mouths of pipe and the bottom sealing socket 5 formation seal cavities the second road pressurized air shown in the arrow E by making progress among the figure.Keep-up pressure, observe the commissure and have or not leakage.Whole process is easy, quick, only consumes cheap pressurized air, is fit to cylindrical shell in enormous quantities and detects one by one.
