Description
Technical field
The present invention relates to a kind of Free Float Type Steam Trap, and in particular to a kind of longer Free Float Type Steam Trap of use time, belongs to
In valve technology field.
Background technology
Freely the ball float of half Free Float Type Steam Trap only one of which half float-ball type is movable part, and opening down, ball float is
Opening and closing element, is sealing member again.Whole sphere all can be very long for sealing, service life, is resistant to water hammer, does not have a consumable accessory, fault-free,
Durable in use, no steam leakage.Rate of back pressure is more than 80%, can arrange saturation temperature condensate, and minimum subcooled temperature is 0 DEG C, firing equipment
In not water, firing equipment can be made to reach optimal heat exchange efficiency.
When device just starts, the air in pipeline and low-temperature condensate enter in drain valve through transmitting tube, in valve
Bimetal leaf emptying element flicks ball float, valve opening, and air and low-temperature condensate are discharged rapidly.When steam enters ball float
Interior, ball float produces to buoyancy, and the temperature in valve raises simultaneously, and bimetal leaf empties component shrinkage, and ball is disclosed and flowed towards valve port, valve
Close.When the steam in ball float becomes condensate, ball float loss of buoyance sinks, valve opening, and condensate is discharged rapidly.Work as steaming
Vapour enters back within ball float, and valve turns off, interruption and continuously work.
But there is a defect to be because, in freely half Free Float Type Steam Trap work process, draining action is very frequent, floats
Club is constantly contacted with water discharge nozzle, leads to it gradually to wear and tear although it is stainless steel material, but because contact connects for rigidity
Touch, be still easy to occur abrasion to finally result in water discharge nozzle damage, affect product service life.
Content of the invention
It is an object of the invention to overcoming above-mentioned weak point, provide a kind of service life longer Free Float Type Steam Trap,
It can be greatly prolonged service life, reduces cost by simply transforming to existing freedom half Free Float Type Steam Trap.
The technical scheme providing according to the present invention, Free Float Type Steam Trap, including valve gap, valve body, ball float, launch tube, send out
Penetrate platform and drainage screen blocks up；It is provided with drainage screen below described valve body to block up, drainage screen is blocked up and connected between launch tube, on launch tube
It is provided with exhaust hole；Described valve inner is provided with transmitting station, and transmitting station is provided with ball float, ball float hollow, and launch tube is located at floating
Inside ball；Valve body is fixedly connected with valve gap；
Described valve body side is provided with water discharge nozzle；Described water discharge nozzle front end is connected with buffer unit, and buffer unit includes reed
With several springs being arranged at below reed；Reed is connected with water discharge nozzle by spring.
Described drainage screen blocks up one end and is provided with water blockoff part, and the other end is connected with import by passage.Described water discharge nozzle leads to
Cross passage to be connected with outlet.
The shape of described reed is identical with water discharge nozzle front end geometry, and center is provided with through hole for draining and aerofluxuss.
Beneficial effects of the present invention：The present invention is by entering to the water discharge nozzle front end of existing freedom half Free Float Type Steam Trap
Row improvement can be come into operation, and its improvement cost is cheap, can greatly prolong the service life of drain valve, automatically, rapidly, continuously
Ground exclusion condensate, the effectively leakage of tissue steam, and obtain more preferable heats.

Specific embodiment
As Figure 1-3：Free Float Type Steam Trap, including valve gap 1, valve body 2, ball float 3, launch tube 5, transmitting station 6 and mistake
Filter screen blocks up 7；It is provided with drainage screen below described valve body 2 and blocks up 7, drainage screen blocks up and connects between 7 with launch tube 5, and launch tube 5 sets
There is exhaust hole 8；It is provided with transmitting station 6, transmitting station 6 is provided with ball float 3, ball float 3 hollow, launch tube 5 inside described valve body 2
Inside ball float 3；Valve body 2 is fixedly connected with valve gap 1；
Described valve body 2 side is provided with water discharge nozzle 4；Described water discharge nozzle 4 front end is connected with buffer unit 9, and buffer unit 9 includes
Reed 9-1 and several springs 9-2 being arranged at below reed 9-1；Reed 9-1 is connected with water discharge nozzle 4 by spring 9-2.
Described drainage screen blocks up 7 one end and is provided with water blockoff part, and the other end is connected with import 10 by passage.
Described water discharge nozzle 4 is passed through passage and is connected with outlet 11.
The shape of described reed 9-1 is identical with water discharge nozzle 4 front end geometry, and center is provided with through hole for draining and aerofluxuss.
When drain valve of the present invention starts, ball float 3 sinks on transmitting station 6, and condensate passed through under inlet outlet pressure differential effect
Filter screen blocks up 7, and is sprayed in ball float 3 by blocking up the exhaust hole 8 on 7 launch tubes 5 being connected with drainage screen.When steam enters
Afterwards, the condensate of ball float 3 is gradually extruded, and increases with steam, and buoyancy suffered by ball float 3 increases, and ball float 3 departs from transmitting station 6.This
When, because the steam that exhaust hole 8 sprays is asymmetric to the momentum of ball float 3 inwall, meanwhile, the distance of ball float 3 outer wall and cavity
Also asymmetric, so that formed promoting ball float 3 to make the moment of transverse rotation, meanwhile, steam in ball float 3 is outflowed due to ball float 3
The pressure reduction that the motion of body causes, forms earial drainage phenomenon, and steam is excluded outside valve pocket with condensate together through exhaust hole 8, prevents
Only form gas to block up and action failure.
Ball float 3 constantly rises, and until it is coincide with water discharge nozzle 4, closes nozzle and terminates, now, by being arranged at draining
The buffer unit 9 of nozzle 4 front end enters row buffering to both, and reed 9-1 is extruded along spring downward to the limit by ball float 3, with
Water discharge nozzle 4 plays good cushioning effect while constituting path, substantially prolongs the service life of water discharge nozzle 4, and then
Extend the service life of whole device, reduce cost.
Sensitivity of the present invention is high, can adjust, internal all components are all by stainless steel making, wear-resistant, and resistance to cavitation, during use
Between long.
