The principle of work and the basic structure form of the new newspaper type of this practicality:
Put self-rescuer into a container with cover, the elastic seal ring that between container and lid, has a rubber-plastics material to manufacture, this O-ring seal also has good compressibility and rebound resilience except that having good sealing property.When container being pressurizeed by lid, the sealed and compression of the air in the container, if intact self-rescuer, the pressure in the container will stably remain on the force value; If the self-rescuer of gas leakage, pressurized air will enter into the internal cavities of self-rescuer by the gas leakage hole, and the pressure in the container will descend lentamente; Dropping to lower force value just can settle out.Under computer control, electronic (pneumatic, hydraulic pressure) push rod drives the covering motion down of many turret vessels, with taking-up or put self-rescuer into, once can detect many self-rescuers simultaneously.The pressure of each container and situation of change thereof are all detected by digital pressure recorder and show, also pass to computer simultaneously.The computer expert crosses timing, calculating, judges that whether qualified self-rescuer to be checked be, and produces functions such as corresponding warning, form printing.
The airtight somascope of automatic control digital display of self-rescuer has three kinds of basic structure forms.
Its first kind of version such as Fig. 2, shown in Figure 3.It has replaced traditional single tube water manometer with digital pressure recorder, thereby has just overcome many shortcomings of former existence, and has had many new advantages.
Its second kind of version as shown in Figure 5.Comparison diagram 2 as can be seen, on the basis of first kind of version, it is contained in two groups of containers on the platform at least, has also settled simultaneously electric screw formula or push rod 12 pneumatic, the fluid-operated piston formula on platform, electric pushrod drives rod 13 and moves up and down; Thereby the capping 9 that has also just driven two containers moves up and down, and after capping moves upward, just can take out or put into self-rescuer; After capping moves downward,, just begin to have checked self-rescuer to seal of vessel and pressurization.This version makes checks that once 2 above self-rescuers become reality.
Its third version has three variations exactly on the basis of second kind of version.Demountable wheel has been settled in first variation exactly on platform, can assign it as go-cart in case of necessity or pull a cart the mobile self-rescuer of checking before the self-rescuer shelf.The computer that the special purpose interface plate is arranged has been installed in second variation exactly additional, and computer is being controlled the electric pushrod correct operation, and a series of functions such as detection, demonstration calculating, judgement, form printing are arranged, and has realized intelligent inspection self-rescuer.The 3rd variation is to have increased electronic scale, makes that this instrument also can be to the self-rescuer inspection of increasing weight.
