Abstract
The utility model discloses a prevent release valve of spraying, be applicable to heating system, lead to the fact the injury to the maintenance personal for vapor blowout in the release valve that prevents to heat, the sealed valve body of the sealed valve body of the first order and the second level of the installation of establishing ties has been designed, and install at the first order and the internal sealed case of the formula of relying on oneself of second level seal valve body cavity, utilize gaseous expend with heat and contract with cold's principle, push away movable valve element up -and -down motion in the valve body, first valve and the alternative switching of controlling the exhaust passage of second valve on the case, make the steam that contains high -temperature water steam at first carry out the cooling first time by the heat supply pipeline through the first sealed valve body of air inlet entering, then it carries out secondary cooling to get into the sealed valve body of second through first exhaust passage, the heat conducts to the external world through hollow cooling cylinder, the cooling of vapor in the hot -air is condensed and flow back in the income heat supply pipeline, the retaining ring that finally slides whereabouts, the second exhaust passage is opened, exhaust emission after the cooling is to external.
Description
Technical field
This utility model relates to heating system technical field, a kind of anti-spraying gas bleeder valve.
Background technology
Hot water pipeline, when water-filling, needs whole for the air in pipe emptyings to ensure the normal circulation of thermal medium, and prevents the corrosion to inner-walls of duct of the oxygen in air.Owing to the proportion of air is less than water, in pipeline, during water-filling, air will accumulate in high point, and the high point at pipeline arranges gas bleeder valve and can be discharged by air.At present, traditional gas bleeder valve often sprays the substantial amounts of steam containing steam disappointing when, splashes to easily make piece surface get rusty on the ferrum class part of surrounding, and injection high-temperature water vapor will also result in threat to the safety of maintainer simultaneously.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, it is provided that a kind of anti-spraying gas bleeder valve.
This utility model solves its technical problem and be the technical scheme is that
A kind of anti-spraying gas bleeder valve, including sealed valve body and self-operated type sealed valve core, the air inlet pipe of UNICOM's heat supply pipeline is offered bottom sealed valve body, top offers second exhaust passage, centre offers first exhaust passage, described self-operated type sealed valve core is bottom end seal, the hollow tubular structure of top end opening；Described spool top protrudes upward the second exhaust passage of described sealed valve body, and valve core outer surface is machined with the second valve, the first valve and stop flange, and is provided with slip back-up ring.The diameter of first exhaust passage and the diameter of the first valve are identical, the diameter of second exhaust passage is more than the diameter of cooling cylinder, diameter less than the second valve, described spool is positioned at inside described sealed valve body and slides up and down along described exhaust passage and can make described second valve closing or open second exhaust passage, make simultaneously described first valve closing or open first exhaust passage, described slip back-up ring along described spool slide up and down can when described second exhaust passage is opened UNICOM or cut off described sealed valve body with the external world contact.
As the further restriction to the technical program, described first order sealed valve body is hemisphere, and there is air inlet pipe lower end, it is possible to be directly threaded in supporting heat supply pipeline, described first order sealed valve body upper end is machined with first exhaust passage, is machined with adpting flange at maximum cylindrical.
As the further restriction to the technical program, described second level sealed valve body is hemisphere, and upper end is machined with second exhaust passage, is machined with adpting flange at maximum cylindrical.
One of the present utility model anti-spraying gas bleeder valve compared with prior art produced by provide the benefit that:
(1) the sufficiently cool liquefaction of steam that two-stage sealing valve body can will carry in steam, becomes liquid and passes back into pipeline, is possible to prevent steam ejection to damage maintainer.(2) without installing extra temperature sensor and controller, the characteristic of expanding with heat and contract with cold fully relying on gas can realize the opening and closing of valve, simple and reliable for structure.(3) complete equipment compact conformation can be installed in existing heat supply pipeline very easily, and Practical Performance is strong.

Detailed description of the invention
Below in conjunction with the accompanying drawings, it is described in detail below of the present utility model.
As shown in drawings, a kind of anti-spraying gas bleeder valve, including first order sealed valve body 3, second level sealed valve body 1 and self-operated type sealed valve core 3；First order sealed valve body is hemisphere, and air inlet pipe 4 is arranged at bottom, and top has first exhaust passage 10, second level sealed valve body to be hemisphere, and second exhaust passage 11 is arranged at top；Self-operated type sealed valve core mainly includes cooling down cylinder 6, and cooling cylinder is that upper end is open, the tubulose that lower end seals, and is machined with the second valve 5, stop flange 8 and the first valve 9 the most successively, and is set with slip back-up ring 7 between stop flange and the second valve.
During work, when in heat supplying pipeline, air pressure is in normal value, gas bleeder valve is in the A condition of accompanying drawing 2, now the second valve 5 of self-operated type sealed valve core is pressed on second exhaust passage 11 under gravity, gas bleeder valve is closed with the external world, and first order sealed valve body and second level sealed valve body are in the conduction state.When in heat supplying pipeline, air pressure is more than normal value, gas bleeder valve is in the B state of accompanying drawing 3, now cooling cylinder 6 under the effect of gas pressure by jack-up until slip back-up ring 7 and upper sealing valve body fitting together tightly, gas bleeder valve is closed with the external world, first order sealed valve body and second level sealed valve body are in UNICOM's state, and thermal current is entered in first order sealed valve body by second level sealed valve body.Hereafter, under the cooling effect of cooling cylinder 6, hot stream temperature in the sealed valve body of the second level reduces, steam coagulation is on cooling body outer wall, and in sealed valve body, air pressure declines simultaneously, and slip back-up ring 7 declines, second level sealed valve body and extraneous conducting, dry thermal current therein is discharged to the external world, and the reduction of air pressure further causes the decline of whole sealed valve core, and gas bleeder valve becomes closed mode again.
In sum, content of the present utility model is not limited in the above embodiments, and those skilled in the art can propose other embodiment within guiding theory of the present utility model, but these embodiments are included within the scope of this utility model.
