The invention relates to the technical field of pressure relief doors, and discloses a folding pressure relief door capable of silencing and automatically reducing pressure, the top end of a lead screw is mounted on the inner wall of a mounting cavity through a bearing, lifting blocks are engaged with the peripheries of the middle and the lower part of the lead screw, and a sealing plate is fixed to the right side of each lifting block; the folding frames are fixed to the surfaces of the first pressure relief door, the second pressure relief door, the third pressure relief door and the fourth pressure relief door at the corresponding positions correspondingly, noise reduction sponges are fixed to the surfaces of the folding frames correspondingly, and the additionally arranged noise reduction sponges are used for sealing gaps among the first pressure relief door, the second pressure relief door, the third pressure relief door and the fourth pressure relief door. The silencing function of the device is further improved; the additionally-arranged sealing plate ascends to drive the first pressure relief door, the second pressure relief door, the third pressure relief door and the fourth pressure relief door to ascend and enter the storage cavity, so that the access space is enlarged, and workers can enter and exit conveniently.
本发明设计涉及泄压门技术领域，且公开了一种可消音并自动降压的折叠式泄压门，所述有丝杠的顶端通过轴承安装于安装腔室的内壁上，所述丝杠的中部与下部外周均啮合有升降块，所述升降块的右侧固定有密封板，所述折叠架分别固定于对应位置的第一泄压门、第二泄压门、第三泄压门与第四泄压门的表面，所述折叠架的表面均固定有消音海绵，加设的消音海绵用于对第一泄压门、第二泄压门、第三泄压门与第四泄压门之间的缝隙进行密封，进而提高了装置的消音功能；加设的密封板随着上升带动第一泄压门、第二泄压门、第三泄压门与第四泄压门上升进入储存腔室中，从而增大了进出的空间，方便工作人员的进出。
