On pipeline, under the Fluid pressure effect flowed in one direction, flap is opened；When fluid opposite direction flowing, by Fluid pressure and
The dead weight of flap and flap act on valve seat, to cut off flowing, for preventing the medium in pipeline from flowing backwards.Check-valves belongs to one
Kind automatic valve, effect is the function of ensureing the medium directed flow in pipeline and will not flow backwards, to try to avert accidents.
Underground garage is equipped with catch pit, and immersible pump is equipped in catch pit.When cold district winter catch pit has water needs
When exclusion, immersible pump starts draining automatically in catch pit.After draining, due to closure of check ring after pump, the pipe after check-valves
Road have ponding presence, if water accumulation of pipeline excludes not in time, can because in pipeline water freezing due to lead to pipeline and valve body bursting by freezing.
Invention content
Technical problem to be solved by the invention is to provide a kind of simple in structure, what is be conveniently operated empties inside check-valves
And the check-valves automatic anti-freezing device of pipeline inside ponding.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of check-valves automatic anti-freezing device, packet
Stop valve, check-valves and drain valve are included, stop valve and check-valves are mounted on main drainage pipeline, and stop valve is in the upper of check-valves
Side；Check-valves includes water inlet, water outlet, valve disc, valve body, valve deck, hinge pin and valve seat, in the bottom of valve body close to valve seat
Place offers by-pass port, by-pass port connecting bypass pipeline, and drain valve is arranged on by-pass line, opens drain valve by check-valves valve
Ponding emptying in internal portion and main drainage pipeline, the valve body side bottom where hinge pin is higher than the valve body-side bottom where by-pass port
The water in portion, such valve body will all be discharged from by-pass port；Drain valve is solenoid valve.
Preferably, further include master controller, the keying of main controller controls immersible pump and drain valve.
Preferably, pressure gauge is installed on the main drainage pipeline below check-valves, for measuring the pressure in pipeline, when
When pressure is more than specified value, master controller sends out instruction, and immersible pump is closed.

Specific implementation mode
The present invention is further illustrated in the following with reference to the drawings and specific embodiments.
A kind of check-valves automatic anti-freezing device, including stop valve 1, check-valves 2 and drain valve 3, stop valve 1 and check-valves 2
On main drainage pipeline 4, stop valve 1 is in the top of check-valves 2；Check-valves 2 include water inlet 5, water outlet 6, valve disc 7,
Valve body 8, valve deck 9, hinge pin 10 and valve seat 11 offer by-pass port 12, by-pass port in the bottom of valve body 8 at valve seat 11
12 connecting bypass pipelines 13, drain valve 3 are arranged on by-pass line 13, open drain valve 3 by 8 inside of check valve body and main row
Ponding emptying in waterpipe 4, the valve body side bottom where hinge pin 10 is higher than the valve body side bottom where by-pass port 12, in this way
The water of valve inner will all be discharged from by-pass port 12；Drain valve 3 is solenoid valve.
Valve body side bottom where hinge pin 10 is higher h than the valve body side bottom where by-pass port 12, h values 5-20mm, excellent
Select 6-10mm.
When the ponding arrival having in catch pit 14, which is opened, pumps position, water-level detecting sensor 16 is believed to master controller 17
Number, master controller 17 sends out instruction, and the immersible pump 15 being arranged in catch pit 14 starts, and the ponding in catch pit 14 is extracted out,
When the water that immersible pump 15 is discharged reaches certain pressure, check-valves 2 is opened, and ponding is discharged to outdoor rain via main drainage pipeline 4
Mouth or rain dirt inspection shaft, when ponding reaches termination of pumping water level, water-level detecting sensor 18 gives 17 signal of master controller, master controller
17 send out instruction, and immersible pump 15 is stopped, and check-valves 2 is closed due to pressure difference.At this moment a certain amount of ponding will rests on
Inside main drainage pipeline and check valve body, when immersible pump 15 is shut down, master controller 17 will give drain valve 3 after a certain time
One open signal, drain valve 3 are opened, and the ponding discharge inside main drainage pipeline and check valve body is will stay on.
It is provided with connecting hose 19 and pressure gauge 20 between the water outlet of immersible pump 15 and the water inlet 5 of check-valves 2, when only
It returns valve 2 to break down when cannot open, the pressure that pressure gauge 20 measures is more than specified value, and pressure gauge 20 is sent out to master controller 17
Signal, master controller 17 send out instruction immersible pump 15 and shut down.
The configuration of the present invention is simple in summary is conveniently operated, can effectively prevent because in pipeline water freezing due to cause pipeline and
Valve body bursting by freezing.
