Abstract
The utility model provides a resistant oily test pressure container, includes the container main part, container main part top is provided with the ascending pipe, install the check valve in the ascending pipe, container main part bottom opening to install the bottom, the installation is sealed between bottom and the opening fills up. Resistant oily test pressure container pours into the experiment medium into through setting up the ascending pipe, check valve in the ascending pipe make the experiment medium can fill smoothly into, avoid the experiment medium in the pressure vessel to volatilize and flow simultaneously, need not not use the lowtemperature cabinet, it is comparatively easy to fill into the operation, easy operation. The sample is packed into through the bottom opening to seal through bottom and sealed the pad, improved the operation convenience of sample loading and unloading, further simplified the operation degree of difficulty of experiment. The bottom passes through threaded connection, and it is easy to make the bottom dismantle, with sealed effect better occasionally. Installation sealed lid in ascending pipe outer end when the check valve damages or became invalid, can seal pressure vessel, has further improved pressure vessel's sealing performance.
Description
Technical field
This utility model relates to a kind of experiment container, specifically, is a kind of pressure vessel carrying out oil resistant test for placing air-conditioner pipe hose lining.
Background technology
In order to ensure that automobile air-conditioning pipe can meet associated vehicle idle call flexible pipe and rubber hose assembly standard, it is necessary to it is carried out volume change test. According to requirement of experiment, it is necessary to first taking flexible pipe inner glue layer is that sample is placed in pressure vessel, is cooled to less than-30 DEG C, makes sample be totally immersed in test medium; After sealing this container, place it in maintenance 70h in the calorstat of 100 DEG C �� 2 DEG C; It is cooled to less than-30 DEG C after placement, then sample is taken out from test medium experiment.
Because of the mixture that test medium is R134A and PAG lubricating oil, R134A at room temperature has again stronger volatility, and pressure vessel is without charging device at present, fill so needing to put into R134A together with pressure vessel cooling in cryostat, and need to seal under cryogenic, avoiding R134A to volatilize, charging operation is comparatively difficult, troublesome poeration. After pressure vessel put into by sample, will being sealed by sealing flange, the bolt installing sealing flange in cryostat further increases the difficulty of operation.
Utility model content
The deficiency that this utility model exists for above-mentioned existing pressure vessel, it is proposed that a kind of new oil resistant test pressure vessel.
Oil resistant test pressure vessel of the present utility model, including container body, described container body top is provided with ascending pipe, is provided with check valve in described ascending pipe; Described container body bottom opening, and bottom is installed, sealing gasket is installed between described bottom and opening.
Preferably, described bottom and container body outer wall are threaded connection.
Preferably, described ascending pipe outer end opening is provided with sealing lid, seals lid and be threaded connection with ascending pipe outer wall.
Preferably, described check valve and ascending pipe inwall are threaded connection.
The beneficial effects of the utility model are: oil resistant test pressure vessel is by arranging ascending pipe injection experiments medium, check valve in ascending pipe makes test medium to be filled with smoothly, avoid the test medium volatilization in pressure vessel simultaneously and flow out, cryostat need not be used, it is filled with operation to be relatively easy to, simple to operate. Sample is loaded by bottom opening, and is sealed by bottom and sealing gasket, improves the operation ease of sample handling, further simplify the operation easier of experiment. Bottom is threaded connection, and makes bottom dismounting easily, has better seal effect simultaneously. Ascending pipe outer end is installed and is sealed lid, when check valve damages or loses efficacy, it is possible to pressure vessel is sealed, further increases the sealing property of pressure vessel.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of oil resistant test pressure vessel.
Detailed description of the invention
In order to be able to further appreciate that structure of the present utility model, feature and other purpose, describing in detail as follows in conjunction with appended preferred embodiment, illustrated preferred embodiment is merely to illustrate the technical solution of the utility model non-limiting this utility model.
Detailed description of the invention of the present utility model is as follows:
Embodiment one:
As it is shown in figure 1, this oil resistant test pressure vessel includes container body 1, container body 1 top is provided with ascending pipe 2, is provided with check valve 3 in ascending pipe 2. Container body 1 bottom opening, and bottom 4 is installed, sealing gasket 5 is installed between bottom 4 and opening.
When testing, being opened by the bottom 4 bottom container body 1, put into by sample in container body 1, cover bottom 4, ascending pipe 2 connects the conveying pipe of test medium.
Test medium is sent in ascending pipe 2 by conveying pipe, and is entered in container body by check valve 3. After test medium has been filled, having been opened by conveying pipe, ascending pipe 2 is sealed by check valve 3, it is to avoid in test medium, volatile substances leaks from ascending pipe 2. Finally pressure vessel is placed in relevant device, proceeds by oil resistant test.
Bottom 4 and container body 1 outer wall are threaded connection, can easily by Unscrew on bottom 4 container body 1 or rotational lock to container body 1 when dismantling bottom 4. Every one screw thread and sealing gasket as the sealing structure between bottom and container body 1, can improve the sealing effectiveness of both junctions.
Embodiment two:
Embodiment two is essentially identical with the structure of embodiment one composition, is distinctive in that:
Ascending pipe 2 outer end opening is provided with sealing lid 6, seals lid 6 and be threaded connection with ascending pipe 2 outer wall. Check valve 3 is the primary seal of ascending pipe 2, but after long-time use, check valve 3 is also easily because aging, and sealing property declines. Ascending pipe 2 is loaded onto sealing of sealing ring and is covered 6 sealings that can be further ensured that ascending pipe 2 opening, and check valve and ascending pipe inwall are threaded connection. Screw thread and sealing ring as the sealing structure sealed between lid and ascending pipe 2, can improve the sealing effectiveness of both junctions.
