Abstract
The utility model relates to a safe type oil tank pressure vent valves arranged on the top of an oil tank, pertaining to the petrochemical industry equipment. The valve cover and the dustproof cover are arranged on the valve body, and the suction valve disc is fixedly arranged on the valve cover, and the exhalation disc is arranged in the valve body. The utility model has the suction valve disc safety valve arranged on the suction valve disc, and the exhalation disc safety valve arranged on the exhalation valve disc, and besides, the body case provided with the jacket. The utility model is compact and reasonable in design. As the airproof material is made of the polyfluortetraethylene and the elastic material, the airproofness can be ensured, the suction valve disc and the exhalation valve disc are both provided with the safety valve to avoid the explosion caused by the ultra high or low internal pressure in the valve.
Description
Technical field:
The utility model relates to a kind of storage tanker breathing valve of safety-type, is installed on the store oil tank deck, belongs to the accessory of equipment in the petroleum chemical industry.
Background technology:
Before the utility model was made, in prior art, this breathing valve mainly by valve gap, suction valve disc, formed by cover of dust, valve body.Because breathing valve is mounted on the store oil tank deck, in jar, plays a part when fluid injection and drawing liquid and the atmosphere intercommunication, keep a jar internal gas pressure balance.The problem that the structure that adopts above-mentioned parts to form exists is easy leakage, and especially valve disc and valve body easy freezing in north cold region or when depositing the material of easy crystallization are taken out flat phenomenon or blasted because of interior pressure is too high thereby jar occurs.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of compact conformation is provided, rationally; Can guarantee its leak tightness effectively; Breathe out, suck set up on the valve disc safety valve can avoid effectively because of valve in the storage tanker breathing valve of the too high or too low safety-type of blasting of pressure.
Main solution of the present utility model is achieved in that
The utility model adopts valve gap 1, cover of dust 5 is installed on valve body 7, sucking valve disc 2 is fixed on the valve gap 1, exhalation valve disc 4 is housed in the valve body 7, it is characterized in that sucking installation suction valve disc safety valve 8 on the valve disc 2, exhalation valve disc safety valve 9 is installed on exhalation valve disc 4, and on housing 7, is added with chuck 10.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, rationally; Because its leakproofing material adopts polytetrafluoroethylene and elastomeric material to combine, and guarantees its leak tightness effectively; Simultaneously breathe out, suck set up on the valve disc safety valve can avoid effectively because of valve in the too high or too low explosion accident that causes of pressure.
Description of drawings:
Fig. 1 is the utility model structural front view;
The specific embodiment:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
This practicality newly will be adopted and be welded with chuck 10 on valve body 7, and breathing valve can lead to steam or conduction oil in chuck, and the suitable temperature of air in the hold-off valve is to avoid in the valve temperature to cross low and valve disc and valve body are freezed.Valve gap 1 and cover of dust 5 are installed on the valve body 7, on the suction valve disc 2 orienting sleeve are housed and are fixed on the valve gap 1, and suction valve disc safety valve 8 is housed between suction valve disc 2 and housing 7.Suck valve disc sealing member 3 sucking to be equipped with between valve disc 2 and the housing 7, suck the making that combines of valve disc sealing member 3 employing polytetrafluoroethylenes and elastomeric material, can guarantee its leak tightness.Exhalation valve disc 4 is housed in valve body 7, exhalation valve disc safety valve 9 is installed on the exhalation valve disc 4, and exhalation valve disc sealing member 6 is housed between exhalation valve disc 4 and housing 7, exhalation valve disc sealing member 6 is same to adopt the making that combines of polytetrafluoroethylenes and elastomeric material, can guarantee its leak tightness effectively.
