Background technique
Existing oil tank in order to ventilate and the anti-explosion fire-retardant security needs, all is equipped with tank valves and oil tank flame trap simultaneously when storing crude oil, light oil or some petrochemicals, play the safety effect of ventilation and back-fire relief respectively.The domestic and international at present fire prevention inhalation valve that also has inhalation valve and flame trap to be integrated.Wherein a kind of structural feature of the inhalation valve of preventing fires is: comprise valve seat, fire retardant core, valve body, valve gap, positive valve, negative pressure valve; Fire retardant core is positioned at valve seat, be provided with in the valve body malleation valve seat, negative pressure valve seat, gas-entered passageway and with advancing/outlet passageway that the external world directly is communicated with, the upper and lower end of valve body connects with valve gap, valve seat respectively.For prevent rainwater from advance/outlet passageway enters in the fire prevention inhalation valve, advance/outlet port of outlet passageway also is provided with overhanging " ear " structure." ear " structure is a kind of waterproof construction, because this " ear " structure is made up of curved surface, is difficult to turning processing, in order to reach the degree of finish of turning processing, often adopt the polishing of manual filing or emery cloth, therefore, this " ear " structure processing difficulties, poor product quality, manufacturing efficiency are low.For convenience convenient processing, the enterprise that has will " ear " structure and valve body individual cast, difference cutting, both is connected with bolt after the completion of processing again, has increased operation and cost so again, and manufacturing efficiency is low equally.
The innovation and creation content
The utility model technical issues that need to address, promptly the purpose of this utility model is for a kind of novel fire-retardant inhalation valve is provided.The rainproof water-bound of this inhalation valve can be processed easy processing by enough machinery.
Technical problem of the present utility model can solve by taking following measure: a kind of novel fire-retardant inhalation valve comprises valve seat, fire retardant core, valve body, valve gap, positive valve, negative pressure valve and rainproof water-bound; Fire retardant core is positioned at valve seat, be provided with in the valve body malleation valve seat, negative pressure valve seat, gas-entered passageway and with advancing/outlet passageway that the external world directly is communicated with, the upper and lower end of valve body connects with valve gap, valve seat respectively, its structural feature is: described rainproof water-bound be built-in, be built in into/outlet passageway in, by be fixed in into/some tilting blades in the outlet passageway constitute, described tilting blade is downward-sloping away from the part of inhalation valve axis.
The utility model technical solution problem, can also take following measure:
The tilting blade that constitutes rainproof water-bound has 1～10.
Described tilting blade with advance/outlet passageway is one-body molded, valve body with advance/outlet passageway is one-body molded.
Describedly advance/also be provided with aperture plate in the gas passage.
The connecting mode of the upper end of described valve gap and valve body is a scyewed joint.
The connecting mode of the lower end of preceding described valve seat and valve body is a scyewed joint.
The utlity model has following outstanding effect:
1, the utility model be located at into/oblique impeller structure in the outlet passageway can with valve body integrally casting, easy processing.Because tiltedly impeller structure is in into/outlet passageway in, its surface by the casting gained can not influence the outward appearance of valve body, so need not process in addition.Thereby, replace " ear " structure of prior art can save manufacturing procedure with oblique leaf waterproof construction, manufacturing process is simple.
2, valve gap of the present utility model, valve seat are scyewed joint with the upper end of valve body, the connecting mode of lower end respectively.Scyewed joint makes the process of valve gap, valve body, valve seat assembling simple and easy, and makes the external diameter of valve gap, valve body, valve seat can be consistent, makes product appearance attractive in appearance.The unanimity of valve gap, valve body, valve seat three external diameter can also make product with compact structure, and packing also can become simple.

Embodiment
Following structure specific embodiment is described in detail the utility model.
Specific embodiment 1:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.Present embodiment comprises valve seat 1, fire retardant core 2, valve body 3, valve gap 4, positive valve 5, negative pressure valve 6 and rainproof water-bound; Fire retardant core 2 is positioned at valve seat 1, be provided with in the valve body 3 malleation valve seat, negative pressure valve seat, gas-entered passageway 7 and with advancing/outlet passageway 8 that the external world directly is communicated with, rainproof water-bound be built-in, be built in into/outlet passageway 8 in, by be fixed in into/some tilting blades 9 in the outlet passageway constitute, tilting blade 9 is downward-sloping away from the part of inhalation valve axis.
In the present embodiment, the upper and lower end of valve body 3 is respectively equipped with screw thread, and adopts the mode of screw thread to connect with valve gap 4, valve seat 1.Describedly advance/be provided with two, five or eight tilting blades 9 in the outlet passageway 8, valve body (3) with advance/outlet passageway (8) is one-body molded.Tilting blade 9 with advance/outlet passageway 8 integral casting formings, tilting blade 9 with advance/sidewall of outlet passageway 8 is connected as a single entity.
The working principle of present embodiment is: when the air pressure in the oil tank was malleation, air pressure was opened positive valve 5, and air comes out from positive valve 5, through advance/outlet passageway 8 outputs to the external world; When being negative pressure in the oil tank, extraneous air is opened negative pressure valve 6, ambient air through advance/outlet passageway 8 comes in, through behind the negative pressure valve 6, enters in the oil tank through gas-entered passageway 7 again.Because set tilting blade 9 has certain inclination, extraneous rainwater is tilted formula blade 9 and blocks and can not enter in the oil tank, and gravitate can not flow in the valve body 3 down along the surface flow of tilting blade 9.Set tilting blade 9 is many more, and rainproof water function is good more.
