Description

Technical Field

[0001] The utility model belongs to the technical field of breakaway valves, in particular to a high-throughput quick breakaway valve. Background Art

[0002] At present, in the gasoline retail industry, the breakaway valve is an indispensable safety protection device. When the fuel gun is still hung on the car and the car is started directly, the pulling force generated by the starting of the car will act on the fuel pump through the fuel gun and the hose, thereby damaging the fuel pump. Once the fuel pump is damaged, fuel leakage is inevitable, which can easily lead to a fire. The breakaway valve is installed between the fuel gun and the hose, or between the long hose and the short hose. When subjected to a certain pulling force, the upper and lower valve bodies of the breakaway valve will detach automatically and close the oil circuit, thereby protecting the fuel pump and preventing accidents.

[0003] At the same time, a breakaway valve with application number 202021157648.7 comprises a first valve body and a second valve body which are arranged at a distance from each other, and connecting sleeves are respectively provided at the opposite end faces of the first valve body and the second valve body, and the end faces of the two connecting sleeves are butted, and the first valve body and the second valve body are fixed by a connecting piece, and a breakaway groove is provided on the connecting piece, and a positioning seat and a balancing block are respectively provided in the first valve body and the second valve body, and one end of the two balancing blocks is butted, and the other end of the balancing blocks slides relative to the positioning seat. The utility model has a simple structure, and when replaced, only the connecting piece needs to be replaced, and there is no need to replace the breakaway valve, which reduces the use cost and has good sealing performance. When assembling the breakaway valve, the front end of the valve body corresponding to the balancing block, the elastic member and the connecting kit is installed. Compared with assembling from the rear end, the installation structure is simple, which is convenient for positioning and assembly with the connecting pipeline, as well as disassembly and replacement of parts, and the installation efficiency is high.

[0004] However, in the implementation of the relevant technology, it was found that the above-mentioned problem exists: a breakaway valve cannot be quickly and completely sealed after being broken, resulting in leakage of liquid inside the breakaway valve, thereby causing accidents and causing greater harm and loss to personnel and equipment.

[0005] To this end, we proposed a high-throughput quick-breakaway valve. Utility Model Content
