Embodiment Construction

[0023] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 , figure 2 As shown, the present invention includes body of wall, top cover 2, explosion-proof sliding door 6. The wall includes a structural steel frame 4, which is welded longitudinally and horizontally by rectangular steel pipes, and has a cross-shaped mesh structure; the inner and outer walls of the structural steel frame 4 are respectively covered with inner panels 10 and The outer panel 3 ; the space enclosed by the other side walls of the structural steel frame 4 , the inner panel 10 and the outer panel 3 is filled with damping sand 9 . The components of damping sand 9 are 95-105 parts of cement, 60-70 parts of medium sand, 18-22 parts of perlite and 28-32 parts of water; the above-mentioned components are mixed uniformly and solidified and dried, and are composed of the above-mentioned components The dam...

Abstract

The invention discloses an explosion-proof room for air pressure test. The explosion-proof room comprises walls, a roof and an explosion-proof sliding door. Each wall comprises a structural steel frame, the inner side wall and the outer side wall of each structural steel frame are covered by an inner face plate and an outer face plate respectively, and the other two side walls of each structural steel frame, the inner face plate and the outer face plate form a space which is filled with damping sand. The roof is provided with a pressure relief port, and a pressure relief window is mounted on the pressure relief port. The explosion-proof room is capable of completely absorbing impact energy generated in explosion while relieving pressure quickly, and further capable of preventing explosion fragments from flying out from the pressure relief window.

Description

technical field [0001] The invention relates to the field of explosion-proof devices for testing, in particular to the field of explosion-proof rooms for air pressure testing. Background technique [0002] Air pressure test refers to the use of a pressure higher than the design index of the pressure vessel to test whether the pressure vessel meets the quality requirements. During the test, unqualified pressure vessels may explode under pressure, endangering the lives of operators in and around the test site and damaging other equipment. The explosion-proof room can be used to block the flying fragments and impact during the explosion in the air pressure pressure test, so as to protect the safety of personnel's life and property. [0003] my country's utility model patent specification ZL200720189879.4 discloses an explosion-proof composite wall, which uses steel plates on the outside and reinforced concrete structure on the inside, but the concrete forms a rigid connection ...
