Description
Technical field
The utility model relates to a kind of vacuum chamber leakage detection apparatus, is mainly the vacuum chamber leakage detection apparatus that the X-fluorescence spectrometer uses.
Background technology
In recent years, the X-fluorescence spectral analysis is constantly expanded in the every profession and trade range of application, has become a kind of every field such as metallurgy, geology, coloured, building materials, commodity inspection, environmental protection, health that are widely used in, and particularly at the RoHS detection field, applies also the most extensively at most.
The X-fluorescence spectral analysis can be analyzed the samples such as solid, powder, bead, liquid, can analyze exactly the contamination of most elements in sample, but analyst coverage is that Be is to U.And have that analysis speed is fast, measurement range is wide, disturb little characteristics.
Most X-fluorescence spectrometer is tested sample by the mode vacuumized in the market.Vacuum chamber used is used the metalwork welding processing to form, and just there is the sealing problem sternly do not caused due to welding in this, and then bring the hidden danger caused because of leakage.
Can't not carry out performing leak test to vacuum cavity owing to there is no special checkout equipment, vacuum cavity just directly is assembled to X-fluorescence spectrum after machining often, after instrument has assembled basically, then it is vacuumized to test.Because do not carry out performing leak test before assembling, this is assembled to X-fluorescence spectrum probability to the vacuum cavity of poor sealing with regard to having increased, and need to carry out dismounting and change to it to it, thereby waste the production time, has reduced work efficiency.
The utility model content
In order to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of vacuum chamber leakage detection apparatus.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of vacuum chamber leakage detection apparatus, comprise gas charge device, vacuum cavity arrangement container, front flexible pipe, rear hose, rigid pipe, threeway link, two-way link, described gas charge device and front flexible pipe one end are tightly connected, rear hose and rigid pipe are tightly connected, rigid pipe is tightly connected by threeway link and vacuum cavity to be measured, and described vacuum cavity is settled filling liquid in container; It is characterized in that: also comprise that air pressure detects valve, the air intake opening of described air pressure detection valve and gas outlet and front flexible pipe and rear hose are tightly connected.
Further, a threeway link at least is installed on the pipeline of described rigid pipe, threeway link and vacuum cavity to be measured are tightly connected; The end of rigid pipe is tightly connected by two-way link and vacuum cavity to be measured.
Further, described threeway link, two-way link are stainless steel bite type link; Described rigid pipe is stainless-steel pipe.
Further, described gas charge device is nitrogen cylinder.
Further, in described vacuum cavity arrangement container, filling liquid is suds or clear water.
The beneficial effects of the utility model are: this device is made simple and convenient, and with low cost, convenient operation, can simple and effectively complete the leak detection work of vacuum cavity before assembling, after avoiding final assembly complete, just finds that there is the situation of gas leakage in vacuum chamber; Once detect the sealing of a plurality of cavitys simultaneously, improve detection efficiency.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, further the utility model is described.
Fig. 1 is structural representation of the present utility model.
In figure: 1, gas charge device, 2, front flexible pipe, 3, air pressure detects valve, 4, rear hose, 5, rigid pipe, 6, the threeway link, 7 vacuum cavities to be measured, 8, vacuum cavity settles container, 9, the two-way link.
Embodiment
A kind of vacuum chamber leakage detection apparatus as shown in Figure 1, comprise gas charge device 1, vacuum cavity arrangement container 8, front flexible pipe 2, rear hose 4, rigid pipe 5, threeway link 6, two-way link 9, described gas charge device 1 is tightly connected with front flexible pipe 2 one ends, rear hose 4 is tightly connected with rigid pipe 5, rigid pipe 5 is tightly connected by threeway link 6 and vacuum cavity 7 to be measured, and described vacuum cavity is settled filling liquid in container 8; It is characterized in that: also comprise that air pressure detects valve 3, the air intake opening of described air pressure detection valve 3 and gas outlet and front flexible pipe 2 and rear hose 4 are tightly connected.
Further, a threeway link 6 at least is installed on the pipeline of described rigid pipe 5, threeway link 6 is tightly connected with vacuum cavity 7 to be measured; The end of rigid pipe 5 is tightly connected by two-way link 9 and vacuum cavity 7 to be measured.
Further, described threeway link 6, two-way link 9 are stainless steel bite type link; Described rigid pipe 5 is stainless-steel pipe.
Further, described gas charge device 1 is nitrogen cylinder.
Further, the liquid injected in described vacuum cavity arrangement container 8 is suds or clear water.
The vacuum cavity of good seal is connected on described rigid pipe by link, then it being inserted to the vacuum cavity that suds or clear water are housed settles in container, suds or clear water surface level should be higher than the vacuum cavity upper surfaces, open the valve of gas charge device inflates in vacuum cavity, when detecting valve, air pressure shows after force value is greater than 0.15～0.20 MPa the valve of closing the gas charge device, observation vacuum cavity surface, if any bubble, emerge, illustrate that there is the welded seal problem in vacuum cavity, otherwise sealing is good, vacuum cavity leakage detecting device of the present utility model can effectively solve in the production of X-fluorescence spectrometer owing to can't detecting in advance the vacuum chamber impermeability, mistake dress and affect the problem of production efficiency.
Abovely by specific embodiment, the utility model is had been described in detail, for those skilled in the art, any change that the design concept of the present utility model of all foundations is made all should be within protection domain of the present utility model.
