Description
Technical field
The utility model relates to the train water tank, relates in particular to the antifreeze filling pipe end of water tank.
Background technology
The antifreeze filling pipe end of train water tank is the product of using ON TRAINS, when water tank lacks water, need carry out water filling to water tank by filling pipe end.When train moved under low temperature environment, the filling pipe end of water tank froze easily, causes and can't carry out water filling to water tank.
In order to guarantee that train still can carry out normal water filling under low temperature environment, make it keep uniform temperature at the outside face wrap round tracing device of filling pipe end, in case frozen.Because filling pipe end and companion's thermic devices are directly exposed in air, have following drawback: corrosion stability is not strong, and koniology also invades water-filling nozzle, polluted water easily; In addition, because expose, companion's thermic devices heat insulation effect is also undesirable.When normal water filling, water often splashes on companion's thermic devices of outside face, directly influences its service life.Therefore, after operation a period of time, filling pipe end usually needs to be serviced or changes new product.
Summary of the invention
In order to overcome the above problems, the utility model provides the antifreeze filling pipe end of water tank of a kind of waterproof and heat-insulating, safe ready, energy-efficient, environment-protecting clean, long service life.
The antifreeze filling pipe end of water tank described in the utility model mainly comprises:
Stem stem, accompany hot device, sleeve, spring, sealing member, capping, wherein stem stem and sleeve are hollow cylinder, and sleeve diameter is greater than the stem stem diameter, and jacket casing is fixed outside stem stem and with stem stem; At the interlayer of sleeve and stem stem, be provided with the hot device of companion at the circumferencial direction of stem stem the first half, be provided with spring at the circumferencial direction of stem stem the latter half, be provided with sealing member and capping between stem stem the first half and the latter half.
When train moved under low temperature environment, the antifreeze filling pipe end of water tank described in the utility model was just started working.Provide power supply by train, accompany hot device to begin to heat up, reach certain temperature within a certain period of time, because sleeve is wrapped in stem stem fully and accompanies hot device, temperature also remains unchanged within the specific limits, even, still can guarantee the normal operation of train, satisfied the demand of train normal operation under harsh environment as under the harsh environment of-45 ° of C.When needing water filling, the compression sleeve inner spring, stem stem exposes, and engages with water supply line, and water filling begins.After water filling is finished, extract water supply pipe, sleeve is got back to original position.
The antifreeze filling pipe end of water tank described in the utility model accompanies hot device to be positioned at entire sleeve inside, and is undertaken heat insulationly by sealing member and capping and the external world, high insulating effect, stable performance, safety factor height, can effectively reduce the loss of heat; Simultaneously effectively completely cut off the invasion and attack of dust, particle and water in the surrounding environment, not only strengthened stem stem corrosion stability, guaranteed that also water quality avoids polluting.
Therefore, the antifreeze filling pipe end leak tightness of water tank described in the utility model is good, thermal drop is little, heat-stable time is long, power consumption is low, is fit to long-term use; Its heat efficiency height, energy savings, installation are simple and convenient, non-maintaining; Also and have explosion-proof, an all weather operation performance; And heating evenly, temperature control is accurately quick, reliability is high, and release heat changes with the variation of temperature; Simultaneously long service life, no leak, saving warm material, pollution-free help environmental protection, belong to that the world is energy-conservation, the low-carbon environment-friendly product.
In order to obtain better effect, the antifreeze filling pipe end of water tank described in the utility model can adopt following measure:
1, the antifreeze filling pipe end of water tank described in the utility model, the bottom of described sleeve is provided with socket cover.Can prevent the invasion and attack of dust, particle and water like this.
2, the antifreeze filling pipe end of water tank described in the utility model, described socket cover top is provided with some sealing members.Can prevent the further invasion and attack of dust, particle and water like this.
3, the antifreeze filling pipe end of water tank described in the utility model, described sealing member are plurality of sector rectangular distribution at a certain angle along the circumferential direction, and the circle centre position that forms full circle in plurality of sector leaves perforate.In the time of need carrying out water filling, water injection pipe is stretched in the sealing member from this center of circle tapping, compression spring, water injection pipe just are connected with the in-to-in stem stem, carry out water filling, can keep filling pipe end not attacked by the external world to greatest extent like this.
4, the antifreeze filling pipe end of water tank described in the utility model, the middle part of described stem stem outside face is provided with a circle annular protrusion, this circle annular protrusion is provided with outside thread, described capping is provided with negative thread, by being threaded between the two, capping is captiveed joint with stem stem, accompany hot device to be sealed between stem stem and the sleeve.
