Kind automatic valve, it is the function of ensureing the medium directed flow in pipeline and will not flow backwards that it, which is acted on, to try to avert accidents.
Underground garage is provided with catch pit, and immersible pump is provided with catch pit.When cold district winter catch pit has water needs
During exclusion, immersible pump automatic start draining in catch pit.After draining terminates, due to closure of check ring after pump, the pipe after check-valves
Road has ponding presence, if water accumulation of pipeline excludes not in time, can cause pipeline and valve body bursting by freezing because of water freezing in pipeline.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in construction, and convenient operation empties check-valves
The check-valves automatic anti-freezing device of ponding inside internal and pipeline.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of check-valves automatic freezing-protective dress
Put, including stop valve, check-valves and drain valve, stop valve and check-valves are arranged on main drainage pipeline, stop valve is in check-valves
Top；Check-valves includes water inlet, delivery port, valve disc, valve body, bonnet, hinge pin and valve seat, close in the bottom of valve body
By-pass port, by-pass port connecting bypass pipeline are offered at valve seat, drain valve is arranged on by-pass line, opens drain valve by non-return
Ponding emptying inside valve body and in main drainage pipeline, the valve body side bottom where hinge pin are higher than the valve body where by-pass port
Side bottom, the water of such valve body will be discharged all from by-pass port；Drain valve is magnetic valve.
Preferably, in addition to 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 determining the pressure in pipeline, when
When pressure exceedes setting, master controller sends instruction, and immersible pump is closed.

Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
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, delivery port 6, valve disc 7,
Valve body 8, bonnet 9, hinge pin 10 and valve seat 11, by-pass port 12, by-pass port are offered at valve seat 11 in the bottom of valve body 8
12 connecting bypass pipelines 13, drain valve 3 are arranged on by-pass line 13, open drain valve 3 by the inside of check valve body 8 and main row
Ponding emptying in waterpipe 4, the valve body side bottom where hinge pin 10 are higher than the valve body side bottom where by-pass port 12, this
The water of sample valve inner will be discharged all from by-pass port 12；Drain valve 3 is magnetic 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 having in catch pit 14, which reaches, opens pump water level, water-level detecting sensor 16 is believed to master controller 17
Number, master controller 17 sends 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 the signal of master controller 17, master controller
17 send instruction, and immersible pump 15 is stopped, and check-valves 2 is closed due to pressure differential.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, the ponding discharge that will stay on inside main drainage pipeline and check valve body.
Connecting hose 19 and pressure gauge 20 are provided between the delivery port of immersible pump 15 and the water inlet 5 of check-valves 2, when only
Return valve 2 to break down when can not open, the pressure that pressure gauge 20 measures exceedes setting, and pressure gauge 20 is sent to master controller 17
Signal, master controller 17 send instruction immersible pump 15 and shut down.
The utility model is simple in construction in summary, convenient operation, can effectively prevent from causing pipe because of water freezing in pipeline
Road and valve body bursting by freezing.
