A calibration device for explosion-proof wave valve production

Abstract

The invention discloses a correction device for the production of explosion-proof wave valves, which relates to the technical field of explosion-proof wave valves, in order to solve the problem that the existing explosion-proof wave valves are easily installed and skewed during production, which directly affects the anti-stress performance of the device, and at the same time affects the performance of the device. aesthetic problem. An anti-scratch ball is installed on the upper end of the workbench, and the anti-scratch ball is connected with the workbench through a card slot, and a first mounting plate is installed on one side of the upper end surface of the workbench, and the first mounting plate is connected with the workbench. The workbench is welded and connected. A second mounting plate is installed on the other side of the upper end surface of the workbench. An adjustment screw is installed between the first installation plate and the second installation plate. The adjustment screw is connected to the first mounting plate. Both the plate and the second mounting plate are connected by screws, and an installation slide block is installed outside the adjustment screw rod, and the installation slide block and the adjustment screw rod are connected through a screw shaft bearing.

Description

technical field [0001] The invention relates to the technical field of explosion-proof wave valves, in particular to a calibration device for the production of explosion-proof wave valves. Background technique [0002] The explosion-proof wave valve is referred to as the valve, which refers to the protective ventilation equipment used in civil air defense projects to ensure uninterrupted ventilation in the project under the condition of air raids. It is generally used in combination with the diffusion chamber. There are two kinds of suspension plate type) and hose type. The explosion-proof wave valve is one of the important protective equipment to ensure the survival of personnel in the tunnel of the position engineering. It is used for ventilation during wartime. The suspension plate is usually open. It is installed at the head of the air intake and exhaust system of the tunnel. The valve is usually open and the tunnel is normally ventilated. When a nuclear attack is encou...
