Abstract
The utility model belongs to the field of benzene canned cars and in particular relates to an anti-overpressure protection device of a pipeline of the benzene canned car. The anti-overpressure protection device comprises a benzene tank and a benzene transmitting pipeline, wherein the bottom of the benzene tank is provided with a benzene outlet; and the benzene outlet is provided with a valve. The anti-overpressure protection device comprises a backflow pressure relief pipe, one end of the backflow pressure relief pipe is connected with the upper part of the benzene tank, the other end of the backflow pressure relief pipe is connected with the benzene transmitting pipeline, the backflow pressure relief pipe is provided with a backflow valve, and the top of the benzene tank is provided with a vent valve used for ensuring air-pressure balance in the pipeline. By adopting the anti-overpressure protection device, when the temperature is relatively high and benzene begins to expand, the backflow valve and the vent valve are opened, and the benzene can flow into the benzene tank by the backflow pressure relief pipe, thereby effectively solving benzene leakage brought by benzene expansion and ensuring safety of workers.
Description
Technical field
The utility model belongs to benzene canning cart field, is specifically related to a kind of anti-over-pressure safety device of benzene canning cart pipeline.
Background technology
Benzene entrucking in the benzene tank to be needed first liquid-transport pipe-line to be communicated with tap hole and the car end hydraulic pipe of benzene tank, open the pipe valve of car end and tank end, by pump benzene is sent in the car, after entrucking is finished, close successively the valve of car end and tank end, the benzene that has entered in the pipeline still can be stayed in the pipeline.Asbestos seal ring is all adopted in the sealing of the pipeline enclosure flange of conveying benzene usually, and its intensity is limited.When summer temp was higher, the benzene expansion can be split up seal ring, caused benzene to leak, and jeopardized personal security.
The utility model content
The purpose of this utility model is to provide a kind of anti-over-pressure safety device of benzene canning cart pipeline, can prevent the benzene leakage that benzene expands and brings by actv..
The technical scheme that the utility model adopts is: a kind of anti-over-pressure safety device of benzene canning cart pipeline; comprise benzene tank and defeated benzene pipeline; the bottom of benzene tank is provided with out the benzene mouth; go out the benzene mouth and be provided with valve, described anti-over-pressure safety device comprises the backflow relief tube, and an end of backflow relief tube is connected with the top of benzene tank; the other end of backflow relief tube is connected with defeated benzene pipeline; and the backflow relief tube is provided with reflux valve, and the top of benzene tank is provided with connection for bbreather pipe, is used for the air pressure balance that guarantees that this pipe is interior.
The beneficial effects of the utility model are: by adopting the utility model, higher in temperature, when benzene begins to expand, open reflux valve and connection for bbreather pipe, benzene can flow in the benzene tank by the backflow relief tube, actv. has solved the benzene leakage that benzene expands and brings, and has guaranteed staff's safety.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Reference numeral: 1, benzene tank, 2, defeated benzene pipeline, 3, go out the benzene mouth, 4, the backflow relief tube, 5, connection for bbreather pipe, 6, valve, 7, reflux valve.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.As shown in the figure: a kind of anti-over-pressure safety device of benzene canning cart pipeline; comprise benzene tank 1 and defeated benzene pipeline 2; the bottom of benzene tank 1 is provided with out benzene mouth 3; go out benzene mouth 3 and be provided with valve 6; described anti-over-pressure safety device comprises backflow relief tube 4, and an end of backflow relief tube 4 is connected with the top of benzene tank 1, and the other end of backflow relief tube 4 is connected with defeated benzene pipeline 2; and backflow relief tube 4 is provided with reflux valve 7, and the top of benzene tank 1 is provided with connection for bbreather pipe 5.
Use principle of the present utility model is: the utility model is by arranging a backflow relief tube 4 between defeated benzene pipeline 2 and benzene tank 1, the top of benzene tank 1 is provided with connection for bbreather pipe 5, higher in temperature, when benzene begins to expand, when opening connection for bbreather pipe 5, the reflux valve 7 of opening on the backflow relief tube 4 can make the benzene in the defeated benzene pipeline 2 be back in the benzene tank 1, actv. has prevented the benzene leakage that benzene expands and brings, and has guaranteed staff's safety.
