Rapid tightness test tool for safety valve

Abstract

The invention discloses a safety valve rapid tightness test tool, which comprises an output oil path and a surge tank; the output oil path comprises a hydraulic pump; a first elastic liquid bag is arranged in the surge tank, the first elastic liquid bag is connected with an oil way of the hydraulic pump, the surge tank is provided with at least one group of flange interfaces for mounting and connecting experimental valves, and the flange interfaces are connected with the first elastic liquid bag. Compared with the prior art, the whole first elastic liquid bag is an elastic component and has a buffering effect, when the output oil way suddenly outputs high-pressure oil, the output oil way outputs the high-pressure oil to the flange connector through the first elastic liquid bag, and at the moment, the first elastic liquid bag can achieve the buffering effect; the disordered pressure brought by the output oil way is counteracted by the elastic potential energy of the first elastic liquid bag, and then the pressure stabilizing effect is achieved. The purposes of buffering the pressure and improving the stability of the output pressure are achieved, and the overall practicability is extremely high.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a rapid tightness test tool for a safety valve. Background technique [0002] Ships need to check the system pressure of the safety valve before the tightness of the system pipeline and before refueling from the gas station to the oil tank. In the process of checking the pressure of the safety valve, special pressure test tools must be used, requiring construction personnel Only by monitoring the pressure in real time can the safety valve meet the pressure requirements before take-off and after the rebound. However, during the construction operation, the existing tools cannot meet the inspection requirements of the safety valve in the workshop, resulting in a long time for inspection and passing the inspection. low rate. In addition, because the safety valve test tool is a manual hydraulic pump, it can only output unstable pressure and flow. The pressure is sometimes...

Problems solved by technology

[0002] Ships need to check the system pressure of the safety valve before the tightness of the system pipeline and before refueling from the gas station to the oil tank. In the process of checking the pressure of the safety valve, special pressure test tools must be used, requiring construction personnel Only by monitoring the pressure in real time can the safety valve meet the pressure requirements before take-off and after the rebound. However, during the construction operation, the existing tools cannot meet the inspection requirements of the safety valve in the workshop, resulting in a long time for inspection and passing the inspection. low rate

In addition, because the safety valve test tool is a manual hydraulic pump, it can only output unstable pressure and flow. The pressure is sometimes high and sometimes small, which is difficult to control. In the process of safety valve tightness in the workshop, when the safety valve burst pressure is about to be reached, The required liquid flow rate is smaller, and the operating space of the manual hydraulic pump is smaller. It depends entirely on the skills and experience of the construction personnel, resulting in unstable safety valve tightness inspection pass rate in the workshop and uncontrollable quality.
