Embodiment
Relevant the utility model is the technological means reaching above-mentioned application target and effect and adopt, and now enumerate better feasible embodiment, and coordinate shown in accompanying drawing, details are as follows:
First as shown in Figure 1, be device schematic diagram of the present utility model.The device simultaneously demarcating multiple stage pressure test instrument of the present utility model, mainly comprises: the first pressure-regulating valve 1, second pressure-regulating valve 2, clean compressed air source 3, first surge flask 4, reference pressure meter 6, first nominal pressure meter 7 etc.
Described clean compressed air source 3 is connected with the air intake opening of the first surge flask 4 by first pressure-regulating valve 1, the gas outlet of described first surge flask 4 is provided with second pressure-regulating valve 2.
In addition, described reference pressure meter 6, and n platform pressure calibration meter is connected on the first surge flask 4 all in a gastight manner.Wherein, n >=1.Depict the first nominal pressure meter 1 and the n-th pressure calibration meter 8 in the embodiment in figure 1.
In addition, improve the pressure stability in surge flask if wish, then can increase the quantity of surge flask, as shown in Figure 2, add the second surge flask 5, wherein the air intake opening of the second surge flask 5 is communicated with the first surge flask 4, the gas outlet of the second surge flask 5 is provided with the 3rd pressure-regulating valve 9.Described reference pressure meter 6, and n platform pressure calibration meter is then connected on the second surge flask 5 all in a gastight manner.
It should be noted that, the quantity of surge flask is not limited with two, can adjust quantity according to actual conditions.
If desired negative pressure pattern, its device composition is similar with Fig. 1 and Fig. 2, and difference is to replace clean compressed air source 3 with vacuum pump (not being shown in detail in figure).
Principle of work of the present utility model is:
1, clean compressed air source (being equipped with corresponding filtration, purification measure etc. as pneumatic accumulator or air compressor) provides stable, without oily clean test air.
