specific Embodiment approach 1

[0005] Specific implementation mode one: (see Figure 1 ~ Figure 3 ) This embodiment includes a lower flange 1, a cylinder body 2, an upper flange 3, a lower bracket 4, three to five poles 5, a return spring 6, a guide post spring 7, a spring baffle 8, and a spring stop Plate adjustment bolt 9, three to five guide columns 11, upper bracket 12, center pillar 15, spacer 16, center pillar bolt 18, return spring adjustment nut 19, return spring baffle 20, door body (bonnet) 23 and central pillar connector 24, the lower flange 1 is fixedly connected to the lower end of the cylinder 2, the upper flange 3 is fixedly connected to the upper end of the cylinder 2, and the lower bracket 4 is fixed on the upper side of the upper flange 3, The door body 23 is arranged on the lower side of the upper flange 3 in the cylinder body 2, and the lower side of the upper flange 3 is provided with a groove 35, and the door body 23 is matched with the groove 35 on the upper flange 3, The central pil...

specific Embodiment approach 2

[0006] Specific implementation mode two: (see figure 1 , figure 2 ) The difference between this embodiment and the specific embodiment one is that it adds a sealing rubber ring 28, and an annular groove 14 is arranged on the upper flange 3 of the matching position with the door body 23, and the sealing rubber ring 28 is located on the inside the ring groove 14. The sealing rubber ring 28 is used to increase the degree of sealing between the door body 23 and the upper flange 3 . Others are the same as in the first embodiment.

specific Embodiment approach 3

[0007] Specific implementation mode three: (see figure 1 , figure 2 ) The difference between this embodiment and the second embodiment is that the door body 23 is composed of an aluminum alloy frame 36 and a stainless steel plate 17 , and the stainless steel plate 17 is fixed on the upper side of the aluminum alloy frame 36 . The composite sealed door body (bonnet) made of stainless steel plate and aluminum alloy frame has the advantages of light weight and strong rigidity, and can realize high-efficiency explosion relief. Others are the same as in the second embodiment.

Abstract

The invention provides a negative pressure super-conducting automatic open-close explosion venting device, relating to a explosion venting device, and aiming to solve the problems of complicated structure, inconvenient regulation for explosion negative pressure and second blasting easily caused after explosion venting in the prior explosioproof devices. A lower flange of the invention is fixedly connected with the lower end of a cylinder body, an upper flange is fixedly connected with the upper end of the cylinder body, a lower bracket is fixed on the upside of the upper flange, a door body is arranged at the underside of the upper flange in the cylinder body, the underside surface of the upper flange is provided with a groove which is matched with the door body, a center support connecting piece is fixed on the center of the upper end surface of the door body, the lower end of the center support is connected with the center support connecting piece, and a return spring is sleeved on the center support. The negative pressure super-conduct automatic open-close explosion venting device has the advantages of accurate explosion negative pressure , rapid explosion venting and complete explosion venting pressure, and high efficiency explosion venting. The negative pressure super-conduct automatic open-close explosion venting device can automatically open, reset and close, the second blasting can not take place after explosion venting, and the replacement and maintenance of the device does interrupt production.

Description

technical field [0001] The invention relates to an explosion-proof device. Background technique [0002] Production equipment in existing power, petroleum, chemical, textile, heating and other systems, as well as media pipelines in structures, generally have the possibility of generating negative pressure and causing an explosion. Once negative pressure occurs, explosion will cause great harm to the country and enterprises Large economic losses, casualties, production equipment can not operate normally, need to stop production for maintenance and replacement of damaged equipment, resulting in a great waste of manpower and material resources. The existing explosion-proof devices have complex structures, troublesome adjustment of the negative pressure of the explosion, and easy occurrence of secondary explosion after the explosion is vented. Contents of the invention [0003] The purpose of the present invention is to provide a negative pressure superconducting automatic op...
