Further, explosion spherical tank sight glass still includes disc 1, and disc 1 is made by Q345R steel material, and is the same with sight glass 7 size, when not using the explosion spherical tank, replaces explosion-proof glass for disc 1.
Further, be connected with flange lid 5 through outer hexagon bolt 2 of little between the flange 4, flange lid 5 is connected through the connector on the lateral wall of big outer hexagon bolt 3 and explosion spherical tank.
In the explosion test process, the device of the utility model can play the following roles:
(1) the water adding depth of the explosion spherical tank is observed in an auxiliary mode.
(2) When the high-speed camera is used, the auxiliary light source can be arranged on the side observation mirror, and the auxiliary light source is clearer when shooting.
(3) And a high-speed camera is arranged on the observation mirror at the other side for observing the crushing shape of the concrete test block.
The observation window material is explosion-proof glass, uses rubber seal between explosion-proof glass and the flange, plays following two aspects effect: the sealing function prevents water in the tank body from flowing out; 2. the pressure resistance function is realized, so that the explosion-proof glass is prevented from being crushed by the flange due to uneven stress caused by the bolts; when the observation mirror is not used, the observation window is replaced by a steel disc made of Q345R material and having the same size as the observation window, so that the service life of the observation mirror is prolonged.
The utility model has the advantages that: the prior art will observe on glass installs the installation section of thick bamboo basically, will install a section of thick bamboo and jar body extension and carry out the aggregate erection again, the utility model discloses directly be connected explosion-proof glass and extension with the flange fixed, easy operation, compare more laborsaving, convenient, save time with prior art, and can increase the light source to a certain extent and be convenient for observe jar internal conditions.
