The hemisphere filter screen of common traditional loose float trap is comprised of steel wire and stainless steel hemisphere plate, some diameter 5mm hole distributes on the stainless steel hemisphere plate, steel wire adopts braided steel wire to form, then steel wire is covered on the stainless steel hemisphere plate, and weld with argon arc welding, then the hemisphere filter screen adopts the endoporus jump ring to be fixed on the ball float top of valve inner, thereby plays a role in filtering; This steel wire normal operation namely was corroded after half a year, because the bore dia on the stainless steel hemisphere plate is 5mm, the steel wire residue of corrosion falls into the valve body bottom through stainless steel hemisphere plate hole, and ball float and valve seat mouth can not be sealed, and causes waste of steam; After the simultaneously steel wire corrosion, the hemisphere filter screen does not have filtration, and rubbish also can enter drain valve inside, thereby causes valve seat to stop up, and causes steam leakage, does not even arrange condensed water, greatly reduces the working life of loose float trap.
In addition because valve body inlet opening pipeline inner wall level too, valve body inlet opening pipeline inner wall and valve interior wall cross section are less, when condensation water quantity is larger, condensed water enters valve body fast, and the steam in the valve body is subject to the restriction of little and less two aspects of valve body inlet opening pipeline inner wall and valve interior wall cross section, valve inner space, cause the steam in the valve body in time not discharge valve body along the pipeline backflow, thereby the stifled problem of gas very easily appears, the steam that namely has certain pressure does not have local discharging in valve body, so that be full of the steam of certain pressure in the valve body, condensed water in the pipeline just can not enter in the valve body smoothly like this, drain valve is not just worked, wait until that always airtight steam is cooled to condensed water gradually in the valve body, behind the pressure decreased, ducted condensed water just can enter in the valve body again, drain valve is started working, so cause drain valve discontinuity to quit work, do not discharge condensed water, affect the gas utilization unit heat exchange efficiency, even can damage gas utilization unit, and the steam that is enclosed in valve inner is wasted, and has affected energy-saving effect.
Summary of the invention
Technical problem to be solved by this invention provides a kind of loose float trap, this drain valve has overcome the defective of traditional drain valve, guarantee the sealing of ball float and valve seat mouth and filtering effect, improved the working life of drain valve, guarantee the normal operation of drain valve and gas utilization unit, improve heat exchange efficiency and energy-saving effect.
For solving the problems of the technologies described above, loose float trap of the present invention comprises the valve body that is provided with inlet opening and delivery outlet, valve seat, valve seat lid and the adjusting screw of being located at the interior ball float of valve body, being located at the valve gap on valve body top and being located at valve body lower portion, this drain valve also comprises the stainless steel cylinder, the through hole of the uniform some diameter 0.7-1mm of described stainless steel cylinder barrel, described stainless steel cylinder is positioned at described valve body and hides the inlet opening of described valve body, described ball float is positioned at described stainless steel cylinder, and the inlet opening upper inside wall of described valve body is provided with the arc groove that upwards arches upward.
