Description

Technical Field

[0001] The invention relates to pipeline equipment, in particular to a blasting door for a pipeline system. Background Art

[0002] At present, the known explosion relief method for pipeline systems and tanks is generally a bursting disc. That is, when the pressure in the pipeline system and tank rises sharply, exceeds the allowable pressure of the pipeline system and endangers the safety of the pipeline system and tank, the bursting disc opens. The bursting disc can only be used once and cannot be calibrated; at the same time, after the pipeline system is purged and pressure tested, it must be replaced, which is not suitable for occasions with frequent overpressure. Summary of the invention

[0003] The purpose of the present invention is to design a blasting door for a pipeline system, which is used for the operating pressure of the pipeline system, the tank, and the dust removal system to protect the safety of the pipeline system, the tank, and the dust removal system equipment from being damaged, and can be used repeatedly to relieve the pressure

[0004] To achieve the above object, the technical solution of the present invention is:

[0006] Preferably, a force adjustment scale is provided on the nut in the buckle assembly.

[0007] The blasting door of the present invention adopts a buckle rebound design, and the blasting pressure can be appropriately adjusted by adjusting the pressure of the spring compressed steel ball; after the blasting, if the sealing strip is not damaged, it can continue to rebound and be used again. It can be used for calibration, purging of pipeline systems, and occasions where pressure is often overpressured; after rapid rebound, the material discharge loss of the process system can be reduced.

[0008] The square flange connecting seat described in the present invention has strip holes on the front and rear end plates to accommodate a snap mechanism and a fixed pin shaft seat for rotating the clamping bracket. A sealing ring is arranged on the flange seat. The sealing plate is pressed onto the sealing ring by a compression spring of the clamping bracket. The clamping bracket is connected to the fixed seat through a pin shaft, and its front end is connected to the snap plate, which presses a steel ball to clamp the clamping hole of the snap plate. According to the blasting pressure, the spring force to compress the steel ball is appropriately adjusted. The sealing plate is pressed onto the sealing ring by the spring in the clamping bracket through a gasket. Two top rings thereof lift up the sheath on the bottom surface of the frame of the clamping bracket when the pipeline system is exploded, and transmit force to the clamping bracket, so that the clamping bracket drives the steel ball to slide out of the clamping hole.

[0009] Beneficial effects of the present invention:

[0010] When this device mechanism is subjected to the bursting pressure in the pipeline system, the air pressure pushes the sealing seat upward. There are two top rings on the sealing seat, which lift up the spring sleeve of the clamping bracket. The top sleeve drives the clamping bracket along the rotating pin shaft, and one end opens upward. The steel ball buckle seat also moves upward with the bracket. At this time, the steel ball buckle seat overcomes the spring force during the upward movement and pushes the steel ball into the steel ball sliding sleeve. When the bracket moves a certain distance, it completely disengages from the steel ball buckle and completely opens the explosion vent. BRIEF DESCRIPTION OF THE DRAWINGS
