Description

Technical Field

[0001] The utility model belongs to the field of self-rescuers, and specifically relates to a self-rescuer performance detection tool. Background Art

[0002] The positive pressure airtightness test device for the self-rescuer can quickly and accurately detect whether the self-rescuer has air leakage, so as to ensure the effective use of the self-rescuer. The pressure indication of the test device adopts the method of pressure gauge indication, which replaces the traditional method of indicating pressure with a water column pressure gauge. Compared with it, it has high measurement accuracy and intuitive and easy-to-read indication. Its base and detection cavity are both one-piece structure formed by sand casting, and in order to ensure the balance of the upper and lower weights of the test device as a whole, the detection cavity is often prepared larger to enhance the stability of the test device during actual operation. The existing positive pressure airtightness test device cannot adjust the volume of the detection cavity according to the size of the compressed oxygen self-rescuer, which reduces the operability of the test, and preparing different test devices for different self-rescuers will inevitably increase the production cost; and the existing positive pressure airtightness test device is manually operated when in use. The pressure handle will cause the position of the sealing cover to shift, resulting in poor airtightness.

[0003] Therefore, a self-rescuer performance detection tool is proposed to solve the above-mentioned drawbacks. Utility Model Content
