Abstract
The utility model discloses an isolating device for a pipeline to pass through a floor or a wall body. The isolating device comprises a sleeve (2) sleeved outside an air pipe (1), wherein an isolator (3) is filled between the air pipe (1) and the sleeve (2). The isolating device which is arranged on the air pipe or the floor or the wall body can greatly relieve noise transfer, has a good vibration-isolation and noise-elimination effect, is durable, convenient to manufacture and install, low in manufacturing cost, and greatly improves the environment. Moreover, the isolating device is beneficial to the working efficiency of the whole system and air distribution, and simultaneously can reduce the work amount of the workers, so that the maintenance work amount is small. More importantly, the working environment of the workers is improved, the noise level is reduced, and the system safety is improved.
Description
Technical field
The utility model relates to the isolation mounting that a kind of pipeline passes floor or body of wall.The sound insulation and noise reduction technical field that belongs to pipeline.
Background technique
In the design of a lot of industrial enterprises factory building, often can run into mechanical ventilation, gather dust, air-conditioning duct passes floor or the situation of body of wall.Vibration equipment passes to pipeline, and the vibration of pipeline internal medium produces noise by floor or the wall connecting place excited vibrational with building, must take quarantine measures from structure.Between airduct and wall hole or floor, do not establish isolation mounting at present, airduct directly contacts with the hole wall of wall hole or floor, can be because of the generation of vibration noise between airduct and wall hole or the floor, noise transmits to be exaggerated in airduct and causes serious noise pollution, cause working environment to worsen, affect the healthy of workman.
Summary of the invention
The purpose of this utility model is, provides a kind of pipeline to pass the isolation mounting of floor or body of wall.The noise pollution that produces during the work that can well solve airduct, to overcome the deficiencies in the prior art, the utility model is simple in structure, and is easy to process, and fabricating cost is low.
The technical solution of the utility model
A kind of pipeline passes the isolation mounting of floor or body of wall, comprises the sleeve pipe that is enclosed within the airduct outside, is filled with spacer between airduct and sleeve pipe.
Aforementioned pipeline passes in the isolation mounting of floor or body of wall, the large 20～30mm of radius of the radius ratio airduct of described sleeve pipe.
Aforementioned pipeline passes in the isolation mounting of floor or body of wall, and the upper orifice of described sleeve pipe is concordant with the plane of floor or body of wall, and the outstanding floor of the lower nozzle of sleeve pipe or body of wall be plane 5～10mm in addition.
Aforementioned pipeline passes in the isolation mounting of floor or body of wall, and described spacer is mixture or other sound absorption vibroisolating material of flax silk and pitch.
Compared with prior art, the utility model has good vibration isolation noise elimination effect by being located at the greatly transmission of reducing noise of isolation mounting on airduct and floor or the body of wall, and is durable in use.Be convenient to fabrication and installation, low cost of manufacture is improved environment greatly.Be conducive to the working efficiency of whole system, be conducive to air distribution, can reduce workman's workload simultaneously, maintenance workload is little, the more important thing is and improves the working environment of workers, reduces noise level, improves Security of the system.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-airduct, 2-sleeve pipe, 3-spacer, 4-floor or body of wall.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
Embodiment.The utility model as shown in Figure 1.A kind of pipeline passes the isolation mounting of floor or body of wall, comprises the sleeve pipe 2 that is enclosed within airduct 1 outside, the large 20～30mm of radius of the radius ratio airduct 1 of sleeve pipe 2.The upper orifice of sleeve pipe 2 is concordant with the plane of floor or body of wall 4, and the outstanding floor of the lower nozzle of sleeve pipe 2 or body of wall 4 be plane 5～10mm in addition.Between airduct 1 and sleeve pipe 2, be filled with spacer 3.Spacer 3 is mixture or other sound absorption vibroisolating material of flax silk and pitch.
Implementation process of the present utility model
During implementation, as shown in Figure 1, the utility model is when implementing, the floor that first airduct 1 is passed or the hole of body of wall 4 enlarge, then a joint diameter is enclosed within airduct 1 outside greater than the sleeve pipe 2 of airduct 1, the internal diameter of sleeve pipe 2 is than the large 50mm of external diameter of airduct 1, and is then with concrete that sleeve pipe 2 is fixing with floor or body of wall 4, the upper orifice of sleeve pipe 2 is concordant with the plane of floor or body of wall 4 in the time of fixedly, and the outstanding floor of the lower nozzle of sleeve pipe 2 or body of wall 4 be plane 10mm in addition.Then fill damping sound insulating material 3 between airduct 1 and sleeve pipe 2, the damping sound insulating material can adopt the mixture of flax silk and pitch, and flax silk plays damping effect, and pitch plays antisepsis; The damping sound insulating material also can adopt other isolated material.Avoid airduct 1 directly to contact with floor or body of wall 4.
Owing to adopted technique scheme, have good vibration isolation noise elimination effect, durable in use.Be convenient to fabrication and installation, low cost of manufacture is improved environment greatly.Be conducive to the working efficiency of whole system, be conducive to air distribution, can reduce workman's workload simultaneously, maintenance workload is little, the more important thing is and improves the working environment of workers, reduces noise level, improves Security of the system.
