Working principle of the present invention is as follows described:
Open state: negative pressure station 7 is opened, and sewage falls into floor drain body 2 from drain cover 1, when sewage gathers one in floor drain body 2
Depthkeeping degree, 20 pressure of sewage cavity are greater than lower 19 pressure of spring, and the 4th valve rod 18 is opened.First plasmas channel, 26 atmospheric pressure passes through
Two or four cavity interface channel 16 enters the second cavity 35, and the second time damper 32 connects vacuum cavity interface channel 38, mends
It fills negative pressure and enters atmospheric pressure much smaller than the two or four cavity interface channel 16, the second cavity 35 becomes atmospheric pressure, due to third cavity
31 connect cavity interface channel 38 by third time damper 28, and third cavity 31 is negative pressure.It is on second elastic diaphragm 12
Atmospheric pressure, lower is negative pressure, and under differential pressure action, diaphragm drives the second valve rod 10 and valve plate 4 to move down, at this time discharge outlet 3 and negative pressure
Cavity 39 is connected to, and sewage is drawn into negative pressure station 7 by suction function.
Closed state: after the sewage emptying in floor drain body 2 and in sewage cavity 20, under the pressure of sewage cavity 20 is less than
19 elastic force of spring, the 4th valve rod 18 are closed, and the two or four cavity interface channel 16 is connected to closing, the second chamber with the first plasmas channel 26
Body 35 slowly restores by the second time damper 32 connection cavity interface channel 38 to negative pressure state, until the second cavity 35
Completely the same with 31 negative pressure of third cavity, the second elastic diaphragm 12 is slowly returned to original state by spring force at this time, valve plate 4
Close discharge outlet 3.
