Portable self-made overpressure chamber

Abstract

The invention belongs to the technical field of overpressure chambers, and particularly discloses a portable self-made overpressure chamber. The portable self-made overpressure chamber comprises a platform body, an overpressure chamber body, door frame angle steel and a door leaf. According to the portable self-made overpressure chamber, putty is arranged between the platform body and the door frame angle steel, the outer side of the putty is brushed with two layers of paint, the sealing performance between the platform body and the door frame angle steel is improved, sealing rubber pads are arranged at a pressure measuring opening and an air inlet, a sealing strip is arranged between the door frame angle steel and the door leaf, the sealing performance of the overpressure chamber is improved, according to a large number of on-site practices, the pressure of the sealed overpressure chamber body can be maintained to be 50 Pa within 10 min, the subsequent test requirement can be completely met, and compared with existing steel plate welding sealing, the portable self-made overpressure chamber has the advantages of being light, thin, portable and easy to install on site, can be combined into different sizes according to civil air defense doors of different models, and is high in flexibility. The industrial sore point can be eliminated, and better conditions are provided for on-site air tightness detection of civil air defense engineering protection equipment in the future.

Description

technical field [0001] The invention relates to the technical field of overpressure chambers, in particular to a portable self-made overpressure chamber. Background technique [0002] At present, there are mainly two types of air tightness testing for protective door equipment in civil air defense projects: on-site inspection and laboratory inspection, among which the laboratory inspection accounts for the vast majority. For the products submitted for inspection, there are overpressure chamber equipment formed on the laboratory site. Therefore, the detection can be carried out effectively. The present invention is mainly aimed at the rapid establishment of the overpressure chamber in the process of on-site inspection. At present, there are few on-site inspections in the industry, and some of them adopt the method of on-site welding of formed steel plates on the door frame, which is troublesome and requires high professional skills of personnel.
