Abstract
The invention discloses a kind of Automatic steam trap Trap, described shell is sequentially provided with upper end water inlet, lower end outlet, self-cleaning filter, slag-drip opening, temperature stress strain piston, self-lubricating seal pair from top to bottom.Valve body is provided with thermal resistance sensor installing hole.Present configuration rationally, manufactures and maintenance cost is low, maintenance is convenient；Good filtration effect, solves the problems, such as to make hydrophobic defective valve, the long service life of valve body because of impurity jam valve element, discharge opeing temperature is adjustable, is adapted to the requirement of different lime set mass rate of emissions and temperature.
Description
Technical fieldThe present invention relates to a kind of Automatic steam trap Trap field, it is related to a kind of self-lubricating seal pair.
Background technologyAll there is more or less or deficiency, for example in various forms drain valve disclosed at present:1. the bellows steam trap of thermostatic often because bellows be heated uneven produce non axial thrust, cause sealing member deflection to ultimately result in hydrophobic defective valve;Although 2. thermodynamic trap parts count is few but machining accuracy is high, energy-saving effect is worst, and the drain valve of the type could be closed when only steam spills, the heat energy of large losses, other movement parts can lead to the abrasion of sealing surface because of long-term and sealing surface collision, and air leakage further increases;3. freedom or lever floating ball type draining valve service behaviour are relatively preferable, but its volume is larger, and heat dissipation capacity is relatively many, and can not use under the high occasion of pressure, and internal structure is more complicated, and number of parts is many;4. it is inverted cartridge type drain valve internal structure complexity, volume is relatively large, is relatively suitable for steady working condition, degree of supercooling is low;5. dual metal type drain valve internal structure is complicated, and number of parts is many, it is desirable to have good sealing surface and sealing member.
In addition:1. above-mentioned drain valve institute draining is saturation water;2. all there are the sealing member of metal and the sealing surface of polish;3. filter effect is poor, finds, leads to because filter effect is bad the ratio nearly 29% of drain valve damage in actual use.
Known hydrophobic structure, tube edge corrosion product may affect valve element closure, and solution is all using before drain valve plus y-type filter or drain valve itself add a drainage screen.Cross the plane filter screen device that current direction has angle）.The defect corrosion product stackeding space that this defecator manifests at the scene is too small, and filter grid pore design moulding is excessive, the corrosion that passed through by hole, erosion product, still may produce erosion, jam to valve core sealed cover.
Content of the inventionDrain valve Temperature Field Design, drain valve designs according to steam power, should be at the condensation end before steam pipe（Section）：I.e. some vapor, due to heat exchange, heat energy dissipation, according to Thermodynamic Law, when close to hydrophobic structure, condenses heat release（Maintain thermal balance）, drain valve gathers certain condensed water, or gathers certain temperature difference（Less than tube edge equilibrium dew point 15-30 DEG C. drain valve reaches the action critical point starting draining, all known drain valves, for the reciprocal effect in the temperature field related to this critical point and heat-insulation layer, does not all have quantitative data to the relation of coagulation and valve event frequency.
Known drain valve scene temperature gather sensor it is desirable to be thermocouple 1., 2. existing design rule standard shows that this temperature sensor, compared with thermal resistance, has significant limitation at some aspects.
It is characterized in that：
There is self-cleaning filter in the entry design of valve, it is characterized in that condensed fluid（Steam）The direction of motion and liquid（Steam）The direction flowing to valve element is the angle of 30-89 degree, and corrosion, erosion slag are fallen to deslagging chamber, regular deslagging by the effect of gravity and centrifugal force.
Default thermal resistance sensor installing hole is the distribution that possible need or monitoring provides data platform basis.
Temperature stress using automobile thermostat strains piston, and the temperature that can set opens intensity TA（Definite value）Poor ± 2.5 DEG C of control, due to being mass, specialized manufacture, so product quality is stable, controlled, for adapting to the requirement of different lime set mass rate of emissions and temperature.Valve is designed with prestressing force adjustment structure, to be adjusted for 2 times according to reality online, reaches preferable effect.
Valve core sealed cover and ball sealer adopt the engineering plastics of PEK class and stainless steel ball to constitute a kind of self-lubricating seal pair.The Channel design structure of liquid outlet makes each valve element for eddy current type, the rotation tangential motion doing unlatching fluid leads to valve ball to rotate positioning at random, thus extending the online service life of seal combination, core is low with the coefficient of friction of valve seat, and self-lubricating self-grind characteristic is good.
For the customized Temperature Field Control heat-insulation layer of drain valve, make the thermo parameters method of valve itself consistent with drain valve working motion principle：I.e. inflow direction temperature is high, and drainage direction temperature is low, and in 138 DEG C of -25 DEG C of line temperature of ambient temperature, the outer naked surface temperature of heat-insulation layer is less than or equal to -5 DEG C.
Combination, for huge discharge process conditions, single entrance can mate three outlets simultaneously.The multiple interfaces form such as national standard pipe arrangement flange or pipe screw thread is pressed in the import and export of valve.
Actual execution structure：Bottom is polyurethaness foaming thermal-insulating, average thickness 100mm, and outer layer is flame-retardant polystyrene.

Specific embodiment
In conjunction with accompanying drawing and preferred embodiment, the invention will be further described. and these accompanying drawings are the schematic diagram simplifying, and the basic structure of the present invention are described in a schematic manner, therefore it only shows the composition relevant with the present invention.
During driving, drain valve temperature is low, and sealing pair is opened, when condensed water passes through tangential inlet（5）Enter, by drainage screen（4）Enter.Current scour valve ball（10）Physical action, ball sealer does not stop to rotate, and realizes self-lubricating, and when ball sealer is contacted with sealing surface, will not be clashed into single point, thus increasing the service life.Cold water passes through outlet（14）Flow out.
When the steam or hot water that have exceeded design temperature pass through, temperature stress strains piston（13）Expand, by ball sealer and sealing surface（8）（PEK material）Fit, reached neither leakage vapourss nor the effect wasting hot water.
The residue filtering out, is concentrated on eddy current effect by gravity（3）Slag trapping cavity, periodic cleaning.
Temperature probe entrance is reserved on trap body（7）, distribution or monitoring for needing provide data platform basis.
