It is larger with material resources input, and the R＆D cycle is longer.
Utility model content
The utility model is directed to the deficiency that above-mentioned prior art is present, and proposes that a kind of nylon Liquid penetrant testing of resistance to refrigerant holds
Device.
The nylon Liquid penetrant testing of resistance to refrigerant container of the present utility model, including container body, described container body one end are set
It is provided with check valve, the opening that the container body other end is set and is provided with end cap, the end cap in the filler pipe put
The heart sets seepage mouthful.
The first glue-line and the second glue-line, first glue-line and the second glue-line are sequentially installed with the end cap from inside to outside
Register of the outer ledge all with container body, be provided with nylon layer, second glue-line in first glue-line and set
It is equipped with steel mesh layer.
Preferably, sealing ring is installed between the end cap inwall and container body outer wall.
Preferably, the end cap is connected through a screw thread with container body outer wall.
Preferably, it is provided with the port of the filler pipe between closure, the port of the closure and filler pipe
Sealing ring is installed, the outer wall of the closure and filler pipe is connected through a screw thread.
Preferably, the check valve outer wall is connected through a screw thread with filling inside pipe wall.
The beneficial effects of the utility model are：The nylon Liquid penetrant testing of resistance to refrigerant container is injected by the filler pipe of setting to be made
Check valve in cryogen, filler pipe ensures that refrigerant smoothly injects, and notifies to avoid the refrigerant in container to volatilize or flow out, makes system
The addition of cryogen need not use cryogenic box, and it is easy that refrigerant is filled with operation.The seepage mouthful of end cap is blocked by two glue-lines, two
Glue-line, which is laminated, is modeled to the structural adhesive layer of sebific duct, it is only necessary to by nylon layer doubling into the first glue-line, you can carry out nylon infiltration real
Test, experimental cost is low, the cycle is short, so as to also shorten the R＆D cycle of nylon.
Sealing ring makes refrigerant all be oozed by nylon layer from seepage mouthful gap sealing between end cap and container body
Go out, it is ensured that detection accuracy.
Bottom is connected through a screw thread, and makes bottom dismounting easy, while there is better seal effect.Install close in ascending pipe outer end
Capping, when check valve is damaged or is failed, can seal to pressure vessel, further increase the sealing of pressure vessel
Performance.Check valve is connected through a screw thread, and fastness and sealing are stronger.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the nylon Liquid penetrant testing of resistance to refrigerant container.
Embodiment
In order to be able to further appreciate that structure of the present utility model, feature and other purposes, in conjunction with appended preferred embodiment
Detailed description is as follows, and illustrated preferred embodiment is merely to illustrate the technical solution of the utility model, and non-limiting practicality
It is new.
Embodiment of the present utility model is as follows：
As shown in figure 1, the nylon Liquid penetrant testing of resistance to refrigerant container includes container body 1, what the one end of container body 1 was set adds
It is provided with note pipe 2 in check valve 3, the opening 4 that the other end of container body 1 is set and end cap 5 is installed, the center of end cap 5 is set
Put seepage mouthful 6.
It is sequentially installed with the first glue-line 7 and the second glue-line 8 in end cap 5 from inside to outside, the first glue-line 7 and the second glue-line 8
Outer ledge all aligns with the opening 4 of container body 1, makes the first glue-line 7 and the second glue-line 8 close to the opening 4 of container body 1
Envelope.
Nylon layer 9, i.e. the first glue-line 7 are provided with first glue-line 7 for doubling nylon layer；Steel is provided with second glue-line 8
Stratum reticulare 10, i.e. the second glue-line 8 are doubling steel mesh layer.The nylon material that nylon layer in wherein the first glue-line 7 is tested for needed for.
When being tested, the nylon of experiment, is made nylon layer, and nylon layer doubling is made into the first glue-line 7 needed for choosing.
First glue-line 7 and the second glue-line 8 are covered to container body 1 successively, and cover end cap 5.
Refrigerant is sent in filler pipe 2 by delivery pipe, and enters by check valve 3 inner chamber of container body 1
In.
After the completion of refrigerant filling, delivery pipe is removed, check valve 3 seals filler pipe 2.
Finally detection container is integrally weighed, is put into after the completion of weighing in relevant device, infiltration examination is proceeded by
Test.
By permeability test, the refrigerant in container body 1 gradually penetrates through the first glue-line 7 and the second glue-line 8, finally
Oozed out by the seepage mouthful 6 on end cap 5.After permeability test terminates, detection container is integrally weighed again, infiltration examination is drawn
Front and rear weight difference is tested, the leakage of the refrigerant measured obtains experimental result.
In order to improve experimental precision, sealing ring 11, sealing ring 11 are installed between the inwall of end cap 5 and the outer wall of container body 1
In the concave hoop type seal groove set positioned at the inwall of end cap 5.Sealing ring 11 is close by the gap between end cap inwall and container body 1
Envelope, it is to avoid refrigerant is from the slot leakage, it is ensured that refrigerant is entirely to pass through the nylon layer 9 in the first glue-line 7, from seepage
What mouth 6 was spilt, it is ensured that the leakage measured can react the permeance property of nylon layer 9 completely.
In order to improve degree of being completely embedded and sealing property, end cap 5 is connected through a screw thread with the outer wall of container body 1.
In order to further avoid refrigerant from leaking, closure 12, closure 12 and filling are installed on the port of filler pipe 2
Sealing ring 13 is installed, the outer wall of closure 12 and filler pipe 2 is connected through a screw thread between the port of pipe 2.Closure 12 and sealing
Circle 13 is by the port sealing of filler pipe 2, when check valve 3 breaks down, it is ensured that container tightness energy.
In order to improve the fastness of check valve, the outer wall of check valve 3 is connected through a screw thread with the inwall of filler pipe 2, prevents refrigeration
Check valve 3 is pushed into container body 1 by high pressure when agent is injected, and causes the seal failure unidirectionally passed through.
