The purpose of the utility model is realized like this:
an air suction performance test device is characterized in that: the vacuum pump comprises a vacuum air pump, an angle valve, a pressure gauge, a first pipeline and a second pipeline, wherein the first pipeline is connected with the second pipeline through the angle valve, the end part of the first pipeline is connected with the vacuum air pump, and an air suction port and the pressure gauge are arranged on the second pipeline.
Furthermore, a first branch pipe and a second branch pipe are arranged on the second pipeline, the air suction port is located at the end portion of the first branch pipe, and the pressure gauge is arranged at the end portion of the second branch pipe.
Further, the air suction port is connected with a safety valve to be detected.
Further, the first pipeline and the second pipeline are perpendicular to each other.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model relates to a suction performance test device utilizes vacuum air pump exhaust pressure, and the manometer can show the vacuum numerical value in the pipeline in real time to regard as the sealing member with the angle valve, reach-80 kPa 6.7 kPa's negative pressure back in the pipeline, close the angle valve, can the vacuum in the maintenance test, convenient operation has improved work efficiency.
Drawings
Fig. 1 is a schematic diagram of the suction performance testing apparatus of the present invention.
In the figure:
the device comprises a vacuum air pump 1, an angle valve 2, an air suction port 3, a pressure gauge 4, a safety valve 5, a first pipeline 6, a second pipeline 7, a first branch pipe 8 and a second branch pipe 9.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1, the utility model relates to an air suction performance test device, including vacuum air pump 1, angle valve 2, manometer 4, first pipeline 6 and second pipeline 7, first pipeline 6 is connected through angle valve 2 with second pipeline 6, and 6 tip of first pipeline are connected with vacuum air pump 1, are provided with first branch pipe 8 and second branch pipe 9 on the second pipeline, have induction port 3 on the first branch pipe 8, and 3 departments of induction port are used for placing the relief valve 5 that waits to detect, and manometer 4 sets up the tip at second branch pipe 9.
The first duct 6 and the second duct 7 are perpendicular to each other.
The working principle is as follows:
placing a safety valve 5 to be detected at an air suction port 3, opening an angle valve 2 to enable a first pipeline 6 to be communicated with a second pipeline 7, opening a vacuum air pump 1, discharging negative pressure to the first pipeline 6 and the second pipeline 7, simultaneously observing the numerical value of a pressure gauge 4, immediately closing the angle valve 2 after the pressure gauge 4 reaches minus 80kPa +/-6.7 kPa to cut off the influence of the vacuum air pump 1 on the first pipeline 6 and the second pipeline 7, keeping the vacuum degrees in the first pipeline 6 and the second pipeline 7, continuously observing the change of the numerical value of the pressure gauge 4, reading the state for 1min, observing the change of the vacuum degree, and finishing the test if the change value of the vacuum degree is zero; and keeping the vacuum degree change value not zero, keeping the state for 10min, and reading the change value, wherein the change value is the air suction performance.
The utility model discloses compare with current suction performance testing arrangement, utilize 1 row of pressures of vacuum air pump, manometer 4 can show the vacuum numerical value in the pipeline in real time to regard as the sealing member with angle valve 2, reach-80 kPa 6.7 kPa's negative pressure back in the pipeline, close the angle valve, can the vacuum in the maintenance test, convenient operation has improved work efficiency.
In the above embodiments, the present invention has been described only by way of example, but various modifications may be made by those skilled in the art after reading the present patent application without departing from the spirit and scope of the invention.
