Abstract
The utility model belongs to the ventilation technology of tunnel or underground engineering and provides a tunnel ventilation air volume regulating and distributing tee, two air outlets of a tee pipe (5) which is made of metal materials are provided with a butterfly valve (3), one end of the butterfly valve (3) is connected with an air outlet end of the tee pipe (5) through a flange (10), the other end of the butterfly valve (3) is connected with a metal pipe, and the butterfly valve is composed of two arc-shaped air doors (6). The tunnel ventilation air volume regulating and distributing tee of the utility model satisfies the requirements for distributing a ventilation pipeline and simultaneously regulates the air volume and the tunnel ventilation air volume regulating and distributing tee has the characteristics of simple structure and reliable work.
Description
Technical field
The utility model belongs to the aeration technology of tunnel and underground construction, mainly proposes a kind of tunnel ventilation air quantity and regulates and diversion three-way.
Background technology
In tunnel and underground engineering construction, in order to accelerate Tunnel Construction Schedule, often excavate with the form of many scope of operations, so new requirement is proposed tunnel ventilation, require each scope of operation behind banger, can both have new wind in time to deliver to the excavation face.Be subjected to the restriction of tunnel cross-section size, consider the problem of engineering cost again, arrange that the multichannel airduct is unrealistic,, must carry out air quantity to ventilation system and regulate and shunt and handle in order to satisfy the ventilating problem of a plurality of scope of operations.Be provided with threeway in the air pipeline in the past, but all can only play simple shunting action, can not regulate, be difficult to satisfy the different requirements of different operating in the face of air quantity to air quantity.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of tunnel ventilation air quantity to regulate and diversion three-way, make its satisfy to air pipeline shunt require the time can regulate air quantity simultaneously, and make it have characteristics simple in structure, reliable operation.
The air quantity that the utility model proposed is regulated and the technical pattern of diversion three-way is: two air outlet of the tee piece that metal material is made is respectively arranged with the dish valve, one end of butterfly valve is connected in the air opening end of tee piece by flange, the other end of butterfly valve is connected with metal tube, and butterfly valve is made up of two semicircle air doors.
The utility model use is: the fresh wind in hole is delivered to air quantity adjusting threeway by airduct and is split into two-way, two butterfly valves of air outlet are regulated to satisfy the demand of each work plane to air quantity, because the butterfly valve of two air outlets is designed to the structure that two semicircle air doors constitute, it is more easy that its air quantity is regulated.
The utlity model has easy to operate, characteristic of simple structure.
