Description
Technical field
The utility model is related to a kind of Free Float Type Steam Trap, and in particular to a kind of use time float-ball type more long is hydrophobic
Valve, belongs to valve technology field.
Background technology
Freely the ball float of the float-ball type of half Free Float Type Steam Trap only one of which half is movable part, and opening down, ball float is
Opening and closing element, is again seal.Whole sphere all can be sealing, and service life is very long, is resistant to water hammer, not have a consumable accessory, fault-free,
It is durable in use, without 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, air and low-temperature condensate in pipeline enter in drain valve by transmitting tube, in valve
Bimetal leaf emptying element flicks ball float, and valve opening, air and low-temperature condensate are discharged rapidly.When steam enters ball float
Interior, ball float is produced to buoyancy, while the temperature in valve is raised, bimetal leaf emptying component shrinkage, ball is disclosed and flows towards valve port, valve
Close.When the steam in ball float becomes condensate, ball float loss of buoyance is sunk, and valve opening, condensate is discharged rapidly.Work as steaming
Vapour is entered back within ball float, and valve is turned off, interruption and continuously work.
But it is because in the freely half Free Float Type Steam Trap course of work, draining action very frequently, is floated to have a defect
Club constantly contacts with water discharge nozzle, causes it to wear and tear gradually, although it is stainless steel material, but due to contact for rigidity connects
Touch, be still easy to generation abrasion and finally result in water discharge nozzle damage, influence product service life.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, there is provided a kind of service life float-ball type more long is hydrophobic
Valve, its by carrying out to the Free Float Type Steam Trap of existing freedom half simple transformation by greatly prolong service life, reduces cost.
According to the technical scheme that the utility model is provided, Free Float Type Steam Trap, including bonnet, valve body, ball float, transmitting are led
Pipe, transmitting station and screen pack are stifled；The valve body lower section is provided with screen pack and blocks up, and screen pack is stifled to be connected between launch tube, is launched
Conduit is provided with exhaust hole；The valve inner is provided with transmitting station, and transmitting station is provided with ball float, and ball float is hollow, launch tube
Inside ball float；Valve body is fixedly connected with bonnet；
The valve body side is provided with water discharge nozzle；The water discharge nozzle front end is connected with buffer unit, and buffer unit includes
Reed and several springs being arranged at below reed；Reed is connected by spring with water discharge nozzle.
The stifled one end of the screen pack is provided with water blockoff part, and the other end is connected by passage with import.The water discharge nozzle leads to
Passage is crossed to be connected with outlet.
The shape of the reed is identical with water discharge nozzle front end geometry, and center is provided with through hole for draining and exhaust.
The beneficial effects of the utility model：The utility model is sprayed by the draining to the Free Float Type Steam Trap of existing freedom half
Mouth front end is come into operation by being improved, and its improvement cost is cheap, can greatly prolong the service life of draining valve, automatic,
Rapidly, condensate, the effectively leakage of tissue steam are continuously excluded, and obtains more preferable heating effect.

Specific embodiment
As Figure 1-3：Free Float Type Steam Trap, including bonnet 1, valve body 2, ball float 3, launch tube 5, transmitting station 6 and mistake
Filter screen stifled 7；The lower section of the valve body 2 is provided with screen pack stifled 7, and screen pack is stifled to be connected between 7 and launch tube 5, is set on launch tube 5
There is exhaust hole 8；Transmitting station 6 is provided with inside the valve body 2, transmitting station 6 is provided with ball float 3, and ball float 3 is hollow, launch tube 5
Inside ball float 3；Valve body 2 is fixedly connected with bonnet 1；
The side of the valve body 2 is provided with water discharge nozzle 4；The front end of the water discharge nozzle 4 is connected with buffer unit 9, buffer unit 9
Including reed 9-1 and several springs 9-2 being arranged at below reed 9-1；Reed 9-1 is connected by spring 9-2 with water discharge nozzle 4
Connect.
Stifled 7 one end of the screen pack are provided with water blockoff part, and the other end is connected by passage with import 10.
The water discharge nozzle 4 is connected by passage with outlet 11.
The shape of the reed 9-1 is identical with the front end geometry of water discharge nozzle 4, and center is provided with through hole for draining and exhaust.
When the utility model drain valve starts, ball float 3 is sunk on transmitting station 6, and condensate is passed through under inlet outlet pressure differential effect
Screen pack stifled 7 is crossed, and is sprayed into ball float 3 by with the exhaust hole 8 on stifled 7 launch tubes 5 being connected of screen pack.When steam enters
After entering, the condensate of ball float 3 is gradually extruded, and as steam increases, buoyancy suffered by ball float 3 increases, and ball float 3 departs from transmitting station 6.
At this moment, the steam for being sprayed due to exhaust hole 8 is asymmetric to the momentum of the inwall of ball float 3, meanwhile, the outer wall of ball float 3 and cavity away from
From also asymmetric so that formation promotes ball float 3 to make the torque of transverse rotation, meanwhile, steam in ball float 3 due to ball float 3 outside
The pressure difference that the motion of fluid causes, formed earial drainage phenomenon, steam by exhaust hole 8 as condensate is excluded outside valve pocket together,
Prevent from being formed gas stifled and act failure.
Ball float 3 constantly rises, and until it coincide with water discharge nozzle 4, closes nozzle and terminates, now, by being arranged at draining
Buffer unit 9 pairs of the front end of nozzle 4 both enter row buffering, 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.
The utility model sensitivity is high, can adjust, and internal all components are wear-resistant all by stainless steel making, and resistance to cavitation makes
It is long with the time.
