Further, the described S-shaped distribution of blast pipe in tank bottom.
The installation method of the air draft silencing means at power network switch station, comprises the air draft silencing means at power network switch station, and its installation steps comprise:
A: tank is set;
On ground below exhaust outlet, excavate the tank of a rectangle or S shape;
B: blast pipe is installed;
One end of blast pipe is fixed on the wall at exhaust outlet place with rivet, then by the S-shaped bottom of controlling at tank of the other end of blast pipe, then will on the exhaust tube wall in tank bottom, smears one deck watertight composition, as pitch etc.;
C: test blast pipe tightness;
After waiting for that watertight composition installs, in tank, pour water, till water logging is not had to blast pipe, open ventilating fan, observe the water in tank, if do not produce bubble, illustrate that blast pipe tightness is good, continuation is poured water in tank, till filling, if produce bubble, close ventilating fan, water storage pool inner water is drained, again smeared watertight composition, until when test do not produce bubble.
The air draft silencing means at power network switch provided by the invention station, not only simple in structure, and easy to use, by noise reduction sponge, absorb the noise of ventilating fan, by tank is set, by the S-shaped bottom that is arranged on tank of blast pipe, and in tank, fill water, by water, reduce the vibration of the blast pipe of the bottom in tank, can greatly eliminate a large amount of noises that ventilating fan produces, effect is very good, by the dual silencing means of noise reduction sponge and tank, near resident's quality of life greatly improving.
