Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
As shown in Figure 1, the utility model provides a kind of filter core bubble point proving installation, comprises back shaft, base and turncap; One end of described back shaft and described turncap are flexibly connected, and the other end of described back shaft is connected with described base; Offer air intake opening and gas outlet on the surface of described base, be communicated with by gas pipe line between described air intake opening and the described gas outlet, described oxygen therapy pipeline is arranged on the inside of described base; And described gas outlet is near the junction of described base and described back shaft, and described air intake opening is away from the junction of described base and described back shaft.Wherein, the other end of back shaft and base are for being fixedly connected with or being flexibly connected.
As shown in Figure 2, back shaft comprises the first thread segment, smooth section and the second thread segment that joins in turn; Described the first thread segment is flexibly connected by screw thread and described base, and described the second thread segment is flexibly connected by screw thread and described turncap.Wherein, in the practical application, the first thread segment length is the 10-25 millimeter; Described the second thread segment length is the 40-60 millimeter; Described smooth section length is the 200-240 millimeter.Preferred length is: the first thread segment length is 17 millimeters; Described the second thread segment length is 55 millimeters; Described smooth section length is 220 millimeters.The mode that employing is threaded, make things convenient for the staff that back shaft is installed to base, and, make things convenient for the staff to adjust the position of turncap on back shaft, and then the distance between adjustment turncap and the base, thereby be applicable to the filter core of different length is carried out the bubble point test experiments.
As shown in Figure 3, also comprise boss, boss is fixedly mounted on the upper surface of described base, and described back shaft is arranged on the center of described boss; Described gas outlet is arranged on the upper surface of described boss, and simultaneously, described gas outlet is positioned at the outside of described back shaft.In the practical application, the diameter of boss is the 22-28 millimeter; The diameter of described back shaft is the 8-12 millimeter; The diameter of described gas outlet is the 4-6 millimeter.Preferred length is: the diameter of boss is 25 millimeters; The diameter of back shaft is 10 millimeters; The diameter of gas outlet is 5 millimeters.
