2, need make regular check on, keep in repair, operating cost is high;
3, be prone to produce water hammer in steam pipe line and the STEAM TRAP;
4, the low temperature season STEAM TRAP freezes, the danger of bursting by freezing;
5, fragile because of traditional STEAM TRAP, it is unreliable to operate, and causes steam leakage big, and energy consumption is high;
6, the steam condensate treating capacity is little, pressure difference and flow restriction.
Because the problems referred to above cause great puzzlement with saving energy and reduce the cost for the ordinary production of enterprise.
The model utility content
For overcoming the technological deficiency of traditional STEAM TRAP, it is a kind of stable, reliable that the utility model provides, and the life-span is long, and operating flexibility is big, need not maintenance, is not afraid of the novel orifice-plate type STEAM TRAP of low temperature.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme.
A kind of novel orifice-plate type STEAM TRAP comprises steam, the import of lime set two-phase medium, lime set media outlet, STEAM TRAP body, orifice plate, several nozzles; Said steam, the import of lime set two-phase medium, lime set media outlet, STEAM TRAP body, orifice plate are through welding, and several nozzles are formed the orifice-plate type STEAM TRAP with orifice plate through being threaded;
Said novel orifice-plate type STEAM TRAP is the Venturi tube structure form, forms the venturi ejection function by several nozzles that are fixed on the orifice plate.
Said steam, the import of lime set two-phase medium, the lime set media outlet is separately positioned on the both sides of STEAM TRAP body, adopts hubbed flange, and welded flange or threaded coupling form are connected together through welding manner and STEAM TRAP body.
Said STEAM TRAP body is a tubular structure, places steam, the import of lime set two-phase medium, and the centre of lime set media outlet is used for the inner welding orifice plate of installing.
Said orifice plate is the plank frame of a circle, has several tapped holes on the plate, and orifice plate uses the mode of welding to be fixed on the inside of STEAM TRAP body between two parties, is used to install and fix several nozzles.
Said several nozzles are the bolt arrangement form; One end of nozzle is processed into outer hexagonal structure; So that rotate fastening nozzle with allen wrench, the other end is processed into the screw thread of different-diameter, is used for being connected assembly with the orifice plate screw; The axial centre of nozzle is processed into the through hole of the different-diameter that requires to confirm according to different process, and several nozzles are fixed on the orifice plate that is processed with screw through the mode correspondence that is threaded.
Through said structure design, the utility model provides a kind of novel orifice-plate type steam trap connection, and its technical characterstic is through technology Calculation and structural design targetedly; With steam, the import of lime set two-phase medium, lime set media outlet, STEAM TRAP body; Orifice plate, several nozzle organic assembling are one.When steam and lime set two-phase medium through several nozzles on the built-in orifice plate of novel orifice-plate type STEAM TRAP the time; The formation venturi sprays; The state of the two-phase medium that makes becomes the eddy current state by laminar condition, thereby has realized the lime set removal, effectively controls the purpose of vapour losses.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed description.
A kind of novel orifice-plate type STEAM TRAP comprises steam, the import of lime set two-phase medium, lime set media outlet, STEAM TRAP body, orifice plate, several nozzles.Said steam, the import of lime set two-phase medium, the lime set media outlet is separately positioned on the both sides of STEAM TRAP body, adopts hubbed flange, and welded flange or threaded coupling form are connected together through welding manner and STEAM TRAP body; Said STEAM TRAP body is a tubular structure, places steam, the import of lime set two-phase medium, and the centre of lime set media outlet is used for the inner welding orifice plate of installing; Said orifice plate is the plank frame of a circle, is processed with several tapped holes on the plate, and orifice plate uses the mode of welding to be fixed on the inside of STEAM TRAP body between two parties, is used to install and fix several nozzles; Said several nozzles are the bolt arrangement form; One end of nozzle is processed into outer hexagonal structure; So that rotate fastening nozzle with allen wrench, the other end is processed into the screw thread of different-diameter, is used for and the orifice plate assembly that is threaded; The axial centre of nozzle is processed into the through hole of the different-diameter that requires to confirm according to different process, and several nozzles are fixed on the orifice plate that is processed with screw through the mode correspondence that is threaded.
