Fuel tank gas tightness detection tool and sealing plug pressing tool

Abstract

The invention relates to the technical field of fuel tanks, in particular to a fuel tank gas tightness detection sealing plug pressing tool and a fuel tank gas tightness detection tool. The fuel tankgas tightness detection sealing plug pressing tool comprises a casing pipe with an opening formed in the lower part, a screw rod and a connector pressing plate, wherein a first connecting and fixing plate is arranged in the circumferential direction of the casing pipe, a first connecting threaded hole is formed in the top part of the casing pipe, the upper end of the screw rod penetrates through the first connecting threaded hole in a matched mode, and the lower end of the screw rod is hinged to the connector pressing plate. The fuel tank gas tightness detection sealing plug pressing tool is used for pressing a sealing plug, reduces the possibility that the sealing plug is not tightly sealed, ensures the sealing effect of the sealing plug, is particularly suitable for the situation that the opening of a fuel tank is an inclined face, and is simple in structure, convenient to use and low in manufacturing cost and operation cost. As the sealing effect of the sealing plug is ensured, thegas tightness detection of the fuel tank is more convenient, and the precision of the detection result is improved.

Description

technical field [0001] The invention relates to the technical field of fuel tanks, in particular to a compression tool for a fuel tank air-tightness detection sealing plug and an air-tightness detection tool. Background technique [0002] The fuel tank needs to be tested for air tightness before use to ensure the safety of the fuel tank. The fuel tank air tightness detection is realized by the fuel tank air tightness detection tool. The existing fuel tank air tightness detection tool includes the clamping workpiece, the test water tank, the compressed air inlet component, the power cylinder, the sealing plug, and the sealing plug. It is used to seal the mouth of the fuel tank. The mouth of the fuel tank refers to the oil pump port, the vent valve port, the dump valve port, etc. The clamping workpiece includes the clamping upper part and the clamping lower part. It moves up and down under the action. In order to reduce the possibility of deformation of the fuel tank during d...

Problems solved by technology

When the existing detection tool is used for detection, since the sealing plug is directly placed on the mouth of the fuel tank to seal the mouth, when the pressure of the compressed air used for detection is relatively high, it is prone to poor sealing, especially When the mouth is inclined, it affects the sealing effect of the sealing plug, which in turn affects the detection of the airtightness of the fuel tank
