Description
Technical field
The utility model relates to the STEAM TRAP in the industrial hot pipe network, particularly a kind of Lavalle type STEAM TRAP.
Background technique
STEAM TRAP has another name called drain valve, also claims hydathode or water of condensation escaper.The effect of STEAM TRAP is because on the equipment that uses steam, only need steam; And the hot equipment of this usefulness is certain to produce water of condensation when carrying out heat exchange, and water of condensation can absorb steam energy and reduce steam quality, thereby the steam heat enthalpy is reduced rate of heat exchange is descended; Water of condensation then becomes harmful fluid; Also sneaked into air and other non-condensable gas simultaneously, become and cause that equipment produces fault and the reason that reduces performance, so STEAM TRAP will quick and complete hydrophobic completely resistance vapour.
STEAM TRAP is being brought into play crucial effects as a vitals in the industrial hot pipe network system in the industrial steam heat exchange.
Many aspects such as the project organization of the existing STEAM TRAP of cause, technical performance, quality of product, function of use exist not enough; Let out vapour pressure release evaporating, emitting, dripping or leaking of liquid or gas phenomenon more; Cause great energy waste, be unfavorable for energy-saving and emission-reduction, therefore be eager existing STEAM TRAP is transformed.The subject matter that existing STEAM TRAP exists:
1, the project organization form of existing STEAM TRAP (comprising mechanical-type, heat static force type, heat power type); Need mechanical motion to accomplish the function of the stifled vapour of draining in the course of the work; Because the work under bad environment of STEAM TRAP; Mechanical motion causes device failure for a long time, has shortened the working life of STEAM TRAP.STEAM TRAP matter time life-span is shorter, makes that the run, drip, leak phenomenon of steam and condensed water is comparatively general in enterprise's hot pipe network, causes the consumption increasing of coal, and the wasting of resources is quite serious, not only increases entreprise cost, and causes a large amount of environmental pollutions.
2, the mentality of designing of original structure has been solidified the structure of existing traditional STEAM TRAP, and traditional STEAM TRAP discontinuous discharging modes give off part steam and produce race vapour pressure release phenomenon when having the discharging condensed water; Wasted the steam resource, caused the pressure release of heat transmission equipment steam simultaneously, temperature reduces thereupon; Production efficiency of products and quality have been reduced; Therefore guarantee the heat exchange amount of heating plant, will strengthen heat supply pressure, all need exceed the actual steam pressure steam supply of using when the steam supply with vapour unit; Cause energy consumption to increase, caused great energy waste;
3, the kind of existing drain valve is a lot, and the performance of having nothing in common with each other owing to select the wrong or improper use of the structural behaviour of STEAM TRAP for use even can cause that valve can't be closed, steam is constantly discharged, exists the phenomenon of a large amount of energy wastes.
4, manufacturing process, the material of existing STEAM TRAP, for many years basic not variation.Because the continuous expansion of STEAM TRAP using scope; Progressively improve with the requirement of the process conditions of hot equipment STEAM TRAP; The influence of many factors such as the temperature of working environment, pressure, water quality, corrosion in addition; Make original manufacturing process, material can not satisfy industrial demand, life of product receives very big influence.Generally speaking, working life was between 3-6 month after existing STEAM TRAP was loaded onto.The tradition STEAM TRAP is because problems such as design principle and quality of product; Working life of often breaking down is of short duration; Can not in time export condensed water causes obstruction reduction steam quality or evaporating, emitting, dripping or leaking of liquid or gas vapour phenomenon to cause steam pressure release loss steam heat enthalpy; Directly influence manufacturing efficiency and strengthened maintenance cost, also caused the waste of steam resource simultaneously.
5, the monotony of function of use
The main function of tradition STEAM TRAP solves drainage problem exactly, and the reclaiming system by traditional STEAM TRAP is set up because each hydrophobic some discharge pressure there are differences, causes to produce steam valve vapour locking phenomenon in the water return pipeline, and recovering effect is unstable and need powerhouse to take back receipts; The tradition STEAM TRAP can't be realized other functions of use such as recycling of the unpowered condensed water in high-altitude because the mode of water is coagulated in the discharging of its discontinuity, lacks the diversity on using.
6, because with hot equipment working condition environmental change, making has evident difference with hot FU time water displacement, and traditional STEAM TRAP can't be adjusted discharge capacity, keeps with hot equipment works fine state;
7, traditional STEAM TRAP volume quality more very much not is convenient for changing and keeps in repair;
8, traditional STEAM TRAP self is not equipped with filtrating equipment, and filter needs buying assembling separately;
9, traditional STEAM TRAP self is not equipped with bypass, in installation process, needs the configuration bypass;
10, the no thermal insulation apparatus of traditional STEAM TRAP self causes the monomer heat loss serious;
The existing ubiquitous subject matter of traditional STEAM TRAP is in time to get rid of condensed water both at home and abroad at present; The vapour pressure release is run in draining simultaneously; Imitate in short-term working life and be easy to generate fault soon and cause hot pipe network to have the energy waste of evaporating, emitting, dripping or leaking of liquid or gas.
