Air-leakage test, also known as Leak Detection or sealing propertytest.Leak hunting and refer to that employing professional method and instrument check the production equipment such as pipeline, storage tank, device or utensil, find whether it exists leakage, orient leakage point particular location and provide leakage rate.Build impermeability when requiring higher equipment, impermeability of any one assembling parts is all very important, and whether the impermeability that the impermeability of these parts determines whole equipment is to a certain extent good.There is no the suitable leakage detection apparatus for gases at high pressure parts in the market, conventional helium mass spectrum leak detection is generally used for the Leak Detection of vacuum equipment, for gases at high pressure equipment then helium Mass Spectrometer Method result can not describe the problem completely, because representative is leak data under vacuum, and equipment price is expensive, clearly can not observe out parts and specifically where there is leakage.
Utility model content
The purpose of this utility model is used for vacuum equipment leakage monitoring for solving current helium mass spectrum leak detection device, can not the leak position of accurate measurements gases at high pressure parts and leakage rate, is not suitable for the technical matters of the device of gases at high pressure parts leak detection.
In order to solve the problems of the technologies described above, the utility model provides a kind of leak-checking apparatus of gases at high pressure parts, nitrogen cylinder endpiece is connected to filter inlet end by 1/4 inch of pipe, filter outlet end is connected to hand valve inlet end by 1/4 inch of pipe, hand valve endpiece is connected to the first port of four-way connection by 1/4 inch of pipe, second port of four-way connection is connected to female threaded nut by 1/4 inch of pipe, 3rd port of four-way connection is connected to male threaded nut by 1/8 inch of pipe, 4th port of four-way connection is connected to rapid-acting coupling by 1/4 inch of pipe, described filtrator, hand valve and four-way connection are separately fixed on fixed head.
Further, each port of described four-way connection is connected with internal threaded nut, internal threaded nut is set with packing ring and is tightly connected described 1/4 inch by adapter to manage or 1/8 inch of pipe.
Further, the length of 1/4 inch of pipe that described four-way connection second port connects is suitable for described female threaded nut and can be immersed in the clear glass cylinder filling distilled water completely.
Further, the length of 1/8 inch of pipe that described four-way connection the 3rd port connects is suitable for described male threaded nut and can be immersed in the clear glass cylinder filling distilled water completely.
Further, the length of 1/4 inch of pipe that described four-way connection the 4th port connects is suitable for described rapid-acting coupling and can be immersed in the clear glass cylinder filling distilled water completely.
The joint categories of the utility model leakage detection apparatus is various, comprise rapid-acting coupling, female threaded nut and male threaded nut etc., and corresponding matched junction can be changed according to the joint form of parts to be detected, the leak detection of the gases at high pressure parts of applicable polytype joint, utilization rate maximizes, comparatively easy with timer, cost is low, by tested parts are immersed in distilled water, observation whether produces bubble or whether bubble increases to judge whether gas leakage, directly can determine leak position, method is simple and efficient.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1. nitrogen cylinder; 2. filtrator; 3. hand valve; 4. four-way connection; 5. fixed head; 6. take over; 7. packing ring; 8. internal threaded nut; 9.1/8 inch of pipe; 10.1/4 inch pipe; 11. rapid-acting couplings; 12. female threaded nut; 13. male threaded nut.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, the leak-checking apparatus of gases at high pressure parts described in the utility model, nitrogen cylinder 1 endpiece is connected to filtrator 2 inlet end by 1/4 inch of pipe 10, filtrator 2 endpiece is connected to hand valve 3 inlet end by 1/4 inch of pipe 10, hand valve 3 endpiece is connected to the first port of four-way connection 4 by 1/4 inch of pipe 10, second port of four-way connection 4 is connected to female threaded nut 12 by 1/4 inch of pipe 10, 3rd port of four-way connection 4 is connected to male threaded nut 13 by 1/8 inch of pipe 9, 4th port of four-way connection 4 is connected to rapid-acting coupling 11 by 1/4 inch of pipe 10, filtrator 2, hand valve 3 and four-way connection 4 are separately fixed on fixed head 5.In order to ensure the impermeability that each port tube of four-way connection 4 connects, each port of four-way connection 4 is connected with internal threaded nut 8, internal threaded nut 8 is set with packing ring 7 and connects 1/4 inch of pipe 10 or 1/8 inch of pipe 9 by adapter 6.
