Embodiment Construction

[0020] The present invention is described in detail below in conjunction with accompanying drawing:

[0021] 1. A pin-type explosion-proof door for industrial boilers, comprising: spring cover 1, spring 2, opening pin 3, explosion-proof door main body 4, movable hinge 5, hinge shaft 6, fixed hinge 7, is characterized in that: fixed hinge 7 and The inner cavity of the boiler is fixedly connected, the movable hinge 5 is fixedly connected with the explosion-proof door main body 4, and the fixed hinge 7 is movably connected with the movable hinge 5 through the hinge shaft 6, so that the explosion-proof door main body 4 can make an angle of 180° with the clockwise hinge axis as the axis The rotation of the spring cover 1 is installed on the main body 4 of the explosion-proof door at an angle of 180° from the hinge axis. There is a built-in spring 2 and an opening pin 3. One end of the opening pin 3 is in contact with the spring 2, and the other end passes through the inner cavity of...

Abstract

The invention discloses a pin type anti-explosion door used for an industrial boiler, and belongs to the safety and explosion prevention field of industrial boilers. The pin type anti-explosion door comprises a spring cover (1), a spring (2), an opening pin (3), an anti-explosion door body (4), a movable hinge (5), a hinge shaft (6) and a fixed hinge (7), and is characterized in that the fixed hinge (7) is fixedly connected with a cavity in the boiler, the movable hinge (5) is fixedly connected with the anti-explosion door body (4), the fixed hinge (7) is movably connected with the movable hinge (5) through the hinge shaft (6), the anti-explosion door body (4) can rotate by 180 degrees in the clockwise direction with the hinge shaft as the axis, the spring cover (1) is arranged at the position, 180 degrees away from the hinge shaft, of the anti-explosion door body (4), the spring (2) and the opening pin (3) are arranged in the spring cover (1), one end of the opening pin (3) makes contact with the spring (2), and the other end of the opening pin (3) enters the cavity in the boiler through an opening in the cavity in the boiler.

Description

technical field [0001] The invention belongs to the field of explosion-proof safety of industrial boilers, in particular to a pin-type explosion-proof door for industrial boilers. technical background [0002] A chamber-fired boiler that uses coal, oil or combustible gas as fuel may cause high furnace pressure during ignition or operation, causing a slight explosion or explosion. In order to protect the safety of the boiler, a device can be installed on the fuel-fired gas-fired steam boiler. When the pressure in the furnace rises to a certain value, it can automatically open the pressure relief, so as to protect the safety of the industrial steam boiler, especially the furnace wall. This device is called a boiler explosion-proof door. The explosion-proof doors currently on the market mainly include gravity-type explosion-proof doors. Bursting disc type explosion-proof doors and spring type explosion-proof doors, the use conditions of gravity type explosion-proof doors ar...
