Abstract
A repeated tensile breakable valve is provided. In the prior the oil-feeding machine, a fixed connection method is used to connect the oil-feeding pipe with the oil-feeding machine, which leads to the fact that the oil-feeding machine can be pulled down if the oil-feeding pipe bears large pulling force, or the oil-feeding pipe can be broken to cause leakage. The technical proposal of the utility model is that a repeated tensile breakable valve arranged on the oil-feeding pipe comprises a valve body, two valve cores, and sealing rings, wherein, one end of the valve body is provided with a safety seat which is connected with the valve body through a safety hook, a valve cover is arranged outside the valve body, and the safety hook and a cover of the safety seat is arranged outside the safety seat. One end of each valve core is supported by a spring, the other end of the spring leans against an elastic blocking ring arranged on the valve body and inside the safety seat through a spring seat, the two valve cores lean against each other during normal running, while the springs are compressed if an outside force exists, and the valve body is separated from the safety seat if the outside force exceeds 1100N, so that the spring on the valve core stretches, and the sealing rings arranged on the valve cores match with and seal the gradually decreasing holes on the valve body and the internal wall of the safety seat, thereby the leakage of oil can be prevented. The separated valve body and the safety seat can be assembled repeatedly with unchanged effect and efficacy.
