Description
Technical Field
The invention belongs to the field of engineering quality detection, and particularly relates to a rapid sealing device for air tightness field detection of a civil air defense door.
Background
The civil air defense engineering has important significance on national air defense strategic deployment, and the quality of air tightness directly determines whether the civil air defense engineering can play a due protection role, so that the life and property safety of people is guaranteed. At present, due to the limitation of field conditions, the air tightness detection of the civil defense door is mainly limited to the production stage of products, the air tightness performance detection after the installation is finished is lack of a uniform measurement sealing device, and the difficulty of the field air tightness detection lies in the construction of a sealing chamber.
Disclosure of Invention
The invention provides a rapid sealing device for the field detection of the air tightness of a civil air defense door, aiming at rapidly and effectively measuring the air tightness performance of the civil air defense door after the installation.
The specific scheme of the invention is as follows: the utility model provides a quick sealing device of civil air defense door gas tightness witnessed inspections, includes sealed cowling, ejector pin, inflation valve, pressure-measuring valve, the terminal surface of sealed cowling is provided with the seal groove, installs the sealing washer in the seal groove, inflation valve and pressure-measuring valve are installed on sealed cowling, the ejector pin is many, the one end of ejector pin is supported on the just right wall of civil air defense door, and the other end will sealed cowling top pressure is sealed through the sealing washer on the peripheral wall of civil air defense door and between the sealed cowling.
Furthermore, the ejector rod is divided into a left-handed thread section, a right-handed thread section and a connecting nut, the left-handed thread section and the right-handed thread section are connected together through the connecting nut, and the connecting nut is rotated to realize the reverse motion of the left-handed thread section and the right-handed thread section, so that the extension and retraction of the ejector rod are realized.
Furthermore, in order to facilitate the installation of the sealing cover, a lifting support is arranged at the lower part of the sealing cover, and the sealing cover is supported on the ground through the lifting support.
The invention is used in such a way that a sealing cover is buckled and pressed on the wall surface around the civil air defense door, then the sealing cover is tightly pressed on the wall surface around the civil air defense door by an ejector rod, the wall surface around the civil air defense door and the sealing cover are sealed by a sealing ring, an inflation tube of an air tightness detector is communicated with an inflation connector arranged on the sealing cover, a pressure measuring tube of the air tightness detector is communicated with the pressure measuring connector on the sealing cover, an inflation pump of the air tightness detector is started to inflate the sealing cover, the air tightness detector stops when the detection requirement is 100Pa, and the air pressure state in the sealing cover is detected to determine the air tightness of the civil air defense door.
The invention comprises a sealing cover, a plurality of ejector rods, an inflation valve and a pressure measuring valve, wherein a sealing groove is formed in the end face of the sealing cover, a sealing ring is arranged in the sealing groove, the inflation valve and the pressure measuring valve are arranged on the sealing cover, one end of each ejector rod is supported on a wall right opposite to a civil air defense door, the sealing cover is pressed on the wall surface at the periphery of the civil air defense door by the other end of each ejector rod, and the wall surface at the periphery of the civil air defense door is sealed with the sealing cover through the sealing ring, so that an airtight chamber and an inflation and pressure measuring channel are constructed, and the rapid sealing of the air tightness field detection of the civil.
