Abstract
The utility model relates to a self-closing explosion-proof device, which comprises a valve body, a hinge, a sealing cover plate, a balancing weight and a limiting rope; one side of the valve body is connected with a hinge; a sealing plate is arranged on the other side of the hinge; a balancing weight is arranged on the upper side of the sealing cover plate; and a limiting rope is arranged between the sealing cover plate and the valve body.
Description
Technical Field
The utility model relates to a self-closing explosion-proof equipment.
Background
The explosion-proof device installed on the existing industrial air pipe takes an explosion-proof membrane as a pressure relief point, and the explosion-proof membrane needs to be replaced after the explosion-proof device works; the explosion-proof device has high operating cost and needs manual recovery after explosion.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problems existing in the prior art and providing an explosion-proof device which has low operating cost and can be automatically recovered.
The utility model discloses specific technical scheme as follows: the self-closing explosion-proof device comprises a valve body, a hinge, a sealing cover plate, a balancing weight and a limiting rope; one side of the valve body is connected with a hinge; a sealing cover plate is arranged on the other side of the hinge; a balancing weight is arranged on the upper side of the sealing cover plate; and a limiting rope is arranged between the sealing cover plate and the valve body.
The utility model discloses the device operation: when a system connected with the device explodes, the generated impact force pushes the sealing cover plate open; the rotation angle of the sealing cover plate is not more than 85 degrees through the limiting rope, and the sealing cover plate can be reset due to self weight after the system is decompressed.
Adopt the utility model discloses behind the device, the initial value that accessible increase and decrease balancing weight adjusting device opened.
Drawings
Fig. 1 is a schematic diagram of the present invention.
The labels in the figure are:
1. the valve comprises a valve body, 2 hinge joints, 3 sealing cover plates, 4 balancing weights and 5 limiting ropes.
The specific implementation mode is as follows:
the present invention will be described in further detail with reference to the following specific embodiments and accompanying drawings.
Example 1:
referring to fig. 1, the self-closing explosion-proof device comprises a valve body 1, a hinge 2, a sealing cover plate 3, a balancing weight 4 and a limiting rope 5; one side of the valve body 1 is connected with a hinge 2; a sealing cover plate 3 is arranged on the other side of the hinge 2; the upper side of the sealing cover plate 3 is provided with a balancing weight 4; and a limiting rope 5 is arranged between the sealing cover plate 3 and the valve body 1.
In the embodiment, when the industrial air pipe protected by the self-closing explosion-proof device explodes, the sealing cover plate 3 is opened under the action of impact pressure generated by explosion; the sealing cover plate resets under the gravity of balancing weight 4 after the device release. The limiting rope can ensure that the opening degree is not more than 85 degrees. The weight of the balancing weight needs to be determined by an experimental machine.
Claims (1)
