Specific embodiment
Invention is further described in detail in the following with reference to the drawings and specific embodiments.
As depicted in figs. 1 and 2, a kind of high negative pressure piston type automatic bleeder, the header tank 2 including upper end opening；Institute
State the top connection collection water cover 1 of header tank 2；Collection water cover 1 and header tank 2 can be designed to be detachably connected, detachably connected
The mode connect can be the modes such as snap thread.Floating ball 4 is equipped in space in the collection water cover 1 and header tank 2；The floating ball
The fixed upper connecting rod 3 in 4 upper surface center, the fixed lower link 10 in the lower surface center of floating ball 4；On the upper end of upper connecting rod 3 is fixed
Piston 13；The fixed lower piston 8 in the lower end of lower link 10；The upper piston 13 is located in the water inlet pipe 14 of collection water cover 1, water inlet
The upper end of pipe 14 is communicated with the bottom of extraction pipeline, and being placed on bottom position can be discharged in time in order to the ponding of bottom；It is described
Lower piston 8 is located in the water inlet pipe 14 of 2 bottom wall of header tank；The diameter of the drainpipe 7 is greater than the diameter of water inlet pipe 14, compared with
The diameter of big drainpipe 7 can quickly be discharged in order to the water in header tank 2, can further, the diameter of the drainpipe 7
It is 2 to 3 times of water inlet pipe 14；14 tube wall of water inlet pipe inside header tank 2 is equipped with the water inlet 15 of hollow out；Positioned at catchmenting
7 tube wall of drainpipe inside case 2 is equipped with the water outlet 9 of hollow out, and the lower edge of 9 hollow out of water outlet is attached to header tank 2
Inner wall；Perforative vertical fixed tubulose inlet channel 12 on the collection water cover 1, the upper end of the inlet channel 12 is set with surface
There is dent 12.2 and hinged for the pressure cover 12.1 of rubber material；Vertical guide rod 11 is equipped in inlet channel 12, it is described to lead
The lower end of bar 11 and floating ball 4 are fixed；When the top edge of the upper piston 13 is flushed with the top edge of water inlet 15, lower piston 8
Lower edge is equal to the height of water inlet 15 in the top of water outlet 9 and the height of the stretching of guide rod 11 12 free end of inlet channel.For
Preferably the sewage in header tank 2 is discharged, can further, the bottom of the header tank 2 is equipped with several with manual
The sewage pipe 5 of valve control on-off.When using the valve on sewage pipe 5 is opened, need to be opened manually pressure cover 12.1, benefit
The sewage in header tank 2 is discharged with pressure balance.Header tank can also be used to support in the bottom firm banking 6 of header tank 2
2。
Working principle: such as attached drawing 1, in the use of the present invention, needing in advance terminating to extraction pipeline on water inlet pipe 14
Bottom, specific connection type be welding.
When water level in header tank 2 is less, buoyancy is smaller, and upper piston 13 and lower piston 8 at this time is in respectively into water
15 lower section of mouth and the lower section of water outlet 9.After occurring ponding in the extraction pipeline there are negative pressure, ponding will be along water inlet pipe
14 enter in header tank 2 from water inlet 15.At this time since lower piston 8 is located at the lower section of water outlet 9, can hinder ponding from
It is flowed out in drainpipe 7.The factor for hindering ponding to flow out simultaneously further includes spreading from the negative pressure in extraction pipeline by water inlet 15
It is all negative pressure state in entire header tank 2.In the case where being negative pressure inside header tank 2, the ponding in header tank 2 is to be difficult
Discharge.
When ponding flows into, the air in entire header tank 2 is negative pressure state, and negative pressure can also be with dent 12.2
The absorption tightly of pressure cover 12.1 be fitted in the upper end of inlet channel 12.Since pressure cover 12.1 is rubber material,
When negative pressure is larger, this dent 12.2 can also be deformed the rubber for becoming to be bonded water inlet pipe 14.
With the rising of water accumulation level, then, the buoyancy of floating ball also slowly increases.When buoyancy slowly overcomes its own gravity
After slowly floating, the top edge of upper piston 13 is flushed with 15 lower edge of water inlet at first, at this time the upper-end contact pressure of guide rod 11
The bottom wall of lid 12.1.
At this time since the beginning of water inlet 15 not yet blocks, continue to rise with water level, guide rod 11 starts to having at this time
The pressure cover 12.1 of pressure deformation presses.What needs to be explained here is that because the inherently deformation because of negative pressure of pressure cover 12.1
Sealing, thus the pressure of guide rod 11 more as a child, be to be not enough to push open pressure cover 12.1, and when pushing away not open pressure cover 12.1,
Guide rod 11 will limit floating ball 4 instead and upper piston 13 rises, and cause water inlet 15 that cannot block, more ponding enter header tank
2.Until pressure cover 12.1 is strutted by unexpected, and a large amount of air enters in header tank 2 after buoyancy is sufficiently large.And upper piston 13
It can be because buoyancy blocks water inlet 15.When the top edge of upper piston 13 is flushed with the top edge of water inlet 15, ponding
Header tank 2 can be stopped flow into because of the blocking of upper piston 13；At this point, the lower edge of lower piston 8 water outlet 9 top and lead
The height that bar 11 stretches out 12 free end of inlet channel is equal to the height of water inlet 15.
Such as attached drawing 2 and Fig. 3, after pressure cover 12.1 is strutted, the thicker drainpipe 7 of the slave diameter of a large amount of ponding moment
Middle discharge.Along with the decline of water accumulation level, upper connecting rod 3 and guide rod 11 can moment decline, upper piston 13 can directly fall to
15 lower edge flush position of water inlet.Pressure cover 12.1 as hinged spring (not marked in figure) cover again it is logical in air inlet
12 upper end of road.There is negative pressure since the presence of dent 12.2 can not be allowed at once in header tank 2 in 12.1 Gai Huihou of pressure cover.?
After floating ball 4 declines, lower piston 8 can also decline, if lower piston 8, above water outlet 9, " gas leakage " caused by dent 12.2 can allow
The water level of ponding continues to be decreased until the lower section completion closure drainpipe 7 that lower piston 8 drops to 9 lower edge of water outlet, plays and prolongs
Shi Zuoyong.
After drainpipe 7 is plugged, the pressure in header tank 2 will be slow raising；It is final to utilize doing something in a fit of pique in extraction pipeline
Handle pressure cover 12.1 is closely pressed in the upper end of header tank 2 by deformation.
