Oiling machine output pipe emergency cutting protection device and oiling machine

Abstract

The invention discloses an oiling machine output pipe emergency cutting protection device and an oiling machine. The device is arranged on an oil conveying pipeline of the oiling machine, and comprises a ball valve body, a valve ball, a valve rod and a handle; the valve ball is rotationally connected into the ball valve body; a connecting base is arranged at the middle part of the upper end of theball valve body; one end of the valve rod rotationally penetrates through the connecting base, and is connected with the valve ball in the ball valve body; and the handle is connected with the otherend of the valve rod. The device further comprises a locking mechanism and a torsion spring; the torsion spring sleeves the valve rod; one end of the torsion spring is fixed with the valve rod, and the other end of the torsion spring is fixedly connected with the connecting base; the locking mechanism is arranged on the valve rod, is positioned between the connecting base and the torsion spring, and is matched and connected with the connecting base; when the ball valve body is connected, the torsion spring is tightened, and the locking mechanism is matched and connected with the connecting base to fixedly constrain the valve rod; and when the matching between the locking mechanism and the connecting base is relieved, the torsion spring drives the valve rod to rotate, and the valve ball isrotated to switch the ball valve body in a closed state, so that the implementation is reliable.

Description

technical field [0001] The invention belongs to the field of emergency disconnection devices for pipelines, in particular to an emergency disconnection protection device for an output pipe of a fuel dispenser and a fuel dispenser. Background technique [0002] With the increasing popularity of automobiles, the number of refueling machines in cities is also increasing. In order to reduce the waiting time of car owners, some gas stations even provide self-service refueling services, that is, car owners perform refueling operations by themselves. After refueling, start the vehicle and drive away without taking out the fuel gun. This will directly cause the pipeline of the fuel gun to be broken. Pull off, cause gasoline to spray accident, even cause immeasurable consequence, and in the prior art, it seems that there is no effective early warning or emergency braking device to deal with this situation. Contents of the invention [0003] In view of the situation in the prior ar...
