Description
Technical Field
The invention belongs to the technical field of exhaust passages, and particularly relates to a sealing socket device and a sealing socket method for an end part of an exhaust passage.
Background
The residential exhaust duct system generally has the problems of smoke and odor tainting, and is a common building quality disease with more complaints of residents, and one of the main reasons is that the joint of the exhaust duct is not closed. Residential exhaust ducts are usually installed by one side or two sides of a wall, and exhaust duct joints close to the wall surface (internal corner positions) are limited by construction conditions, so that leakage is easy to occur, and the residential exhaust ducts are difficult to repair. The oil smoke gas in the exhaust passage leaks outwards through the unsealed part of the joint, so that the indoor air is polluted, and the health of residents is harmed.
At present, residential exhaust ducts are generally connected in a butt joint mode, namely a layer of polymer mortar is coated on the upper end of the exhaust duct, the lower end of the other exhaust duct is aligned and installed on the upper end of the exhaust duct, and joints among the exhaust ducts are sealed by the polymer mortar. The disadvantages of this type of docking approach are:
1) because the wall thickness of the exhaust passage is thin (generally 5mm-15mm), and the end surface shape is a plane structure, the polymer mortar layer coated on the upper end surface of the exhaust passage is easy to have the phenomenon of local or even complete falling in the process of installing the exhaust passage, once the polymer mortar layer falls off, the falling polymer mortar layer is difficult to repair at the position close to the wall surface, the tightness of the joint is difficult to ensure, and the smoke gas leakage is inevitable.
2) Because the exhaust passage is made of cement mortar, the strength of the exhaust passage is poor, and the two ends of the exhaust passage are most easily damaged in the processes of loading, unloading, transportation and installation, so that quality problems such as corner missing, port collapse, cracking and the like occur, and the phenomenon of smoke leakage caused by the fact that the joint is not closed is inevitably caused.
3) The end face of the exhaust passage manufactured by hand is inaccurate in size, and dislocation and gaps are easy to occur when the exhaust passage is butted, so that the joint is not closed, and smoke gas leaks.
In order to solve the problem that the joints of the residential exhaust ducts are not closed, in recent years, a socket type connecting method of the residential exhaust ducts is developed, namely a T-shaped or H-shaped socket connecting piece is arranged at the joints of the exhaust ducts. The socket connecting piece and the residential exhaust duct are two mutually separated components, and the socket connecting piece is bonded to the end part of the exhaust duct through polymer mortar when the exhaust duct is installed. The socket connection mode solves the first problem and the problem of falling off of polymer mortar at the joint of the exhaust duct, but the following two problems still exist:
1) during the loading and unloading, transportation and installation processes of the exhaust passage, the end part of the exhaust passage is still easy to be damaged; if the depth of the damage exceeds the depth of the socket connecting piece, the tightness of the joint of the exhaust passage cannot be ensured, and the problem of smoke leakage still occurs.
2) For the exhaust passage made by hand, because the size of the end surface is inaccurate, the width of the socket connecting piece needs to be increased for the convenience of socket connection of the exhaust passage, and as a result, a part of the socket connecting piece extends into the exhaust passage, so that the effective ventilation area of the exhaust passage is reduced, the wind resistance is increased, and the smoke emission effect is reduced. The other part of the socket piece protrudes outwards, which is not beneficial to plastering of the peripheral surface of the exhaust passage.
Therefore, the existing residential exhaust duct needs to be improved, the problem of tightness at the joint of the exhaust duct is thoroughly solved, the smoke is prevented from leaking, and the phenomena of smoke and odor tainting are prevented.
