Problems solved by technology

At present, the detection of air respirators is usually sent to the manufacturers of air respirators, and multiple devices are used to test each function one by one on the production test line, so the detection process is cumbersome, the detection period is also long, and the cost is quite high. High, which brings a lot of inconvenience to the unit using the air respirator

Embodiment Construction

[0021] Examples, see figure 1 Shown: air respirator tester, the air respirator involved includes components such as face mask, pressure reducing valve, medium pressure tube, air supply valve, exhalation valve and inhalation valve.

[0022] Specifically:

[0023] The air respirator tester includes: artificial head mold H, respirator connection port C and other components. The artificial headform H is used to wear the mask. The artificial headform H communicates with the artificial lung L through the eleventh solenoid valve SV11, and the artificial lung L is connected with the first motor M1. That is, after the first motor M1 operates, it drives the artificial lung L to produce an action similar to breathing. Meanwhile, the artificial headform H has a first air port H1 connected to the exhalation valve and a second air port H2 connected to the inhalation valve.

[0024] The respirator connection port C includes a first respirator connection port C1, a second respirator conne...

Abstract

The invention discloses an air respirator detector. The air respirator includes a mask, a pressure reducing valve, a medium pressure pipe, an air supply valve, an exhalation valve and an inhalation valve. The air respirator detector includes: artificial Head mold, artificial lung, several ventilator connections, several solenoid valves, several pressure sensors and other components. The air respirator detector can perform comprehensive functional testing on all important parts of the air respirator, avoiding the need to send the respirator to the manufacturer's testing line for item-by-item testing and then the testing process during regular testing of the previous air respirator. It is cumbersome, the detection cycle is long, and the detection cost is also high.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to an air respirator testing instrument. Background technique [0002] Air respirators are also known as air-storage gas masks, sometimes also called fire masks. Air respirators are widely used in fire protection, chemical industry, shipbuilding, petroleum, smelting, warehouses, laboratories, mines and other departments, for firefighters or emergency rescue personnel to breathe safely and effectively in various environments such as dense smoke, poisonous gas, steam or lack of oxygen. Carry out fire fighting, emergency rescue and disaster relief and ambulance work. Air respirators use compressed gas cylinders as the gas source, and the gas contained in the cylinders is compressed air. At present, the detection of air respirators is usually sent to the manufacturers of air respirators, and multiple devices are used to test each function one by one on the production test li...
