Problems solved by technology

[0004] However, during use, due to the long-term impact of the pin ③, the pin ③ is subjected to short-term tensile impacts during the frequent start and stop of the hydraulic system, and the rubber hose is pulled during refueling operations, and is prone to fatigue and fracture, causing the breakaway valve to be broken in the non-standard position. Disconnect under vehicle pulling conditions

Abstract

The invention relates to a valve, in particular to an emergency release coupler. The emergency release coupler comprises a first valve body, a second valve body connected with the first valve body, ahousing outside the first valve body and the second valve body, a first emergency release member for limiting relative movement of the housing and the first valve body, and a second emergency releasemember for limiting relative movement of the first valve body and the second valve body. In the axial direction of the first valve body, a first gap between the first emergency release member and thehousing is smaller than a second gap between the second emergency release member and the first valve body. Due to the fact that the first emergency release member bears tensile force before the secondemergency release member, when a rubber pipe is impacted by short-time tensile force in the process that a hydraulic system is frequently started and stopped or the rubber pipe is pulled in the oiling operation, the first emergency release member firstly absorbs the tensile force impact and plays a buffering role, and fatigue fracture of the second emergency release member is avoided.

Description

technical field [0001] The invention relates to a valve, in particular to a breakaway valve. Background technique [0002] In the fuel tanker industry used in gas stations, in order to avoid problems such as a large amount of fuel leakage caused by the fuel gun being inserted into the fuel tank when the vehicle is started, the vehicle pulls the fuel tanker, and the oil delivery pipe between the fuel gun and the tanker body is usually Install the breakaway valve. [0003] figure 1 is a structural schematic diagram of a breakaway valve in the related art, such as figure 1 As shown, the breakaway valve includes two valve bodies ①, two valve cores ② and pins ③ fixing the two valve bodies ①. When the pull-off valve is subjected to a tension exceeding its setting, the pin breaks, and the two valve bodies ① will be automatically disconnected, one end stays at the end of the oil gun, and the other end stays at the end of the fuel dispenser body, and the two valve cores ② separate...
