Embodiment Construction

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

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

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] Pneumatic test refers to using a pressure higher than the design index of the pressure vessel to detect whether the pressure vessel can meet the quality requirements. During the test, a pressure vessel with unqualified quality may explode under pressure, endangering the lives of operators in the test site and its vicinity, and also damaging other equipment. The explosion-proof room can be used to block the flying debris and impact during the explosion in the air pressure test to protect the life and property of personnel. [0003] my country's utility model patent specification ZL200720189879.4 discloses an explosion-proof composite wall, which uses steel plate on the outside and reinforced concrete structure on the inside. However, the concrete forms a rigid connection with the...
