Device for detecting airtightness of fuel filter

Abstract

The invention relates to a device for detecting the airtightness of a fuel filter. The device comprises a water tank. The left and right side walls of the water tank are fixedly connected with a left shaft base and right shaft base respectively; a rotation shaft which is hollow and the two ends of which are sealed is bridged between the two shaft bases; the side wall at one end is connected with a compression wind pipe, and the other end is provided with a hand wheel; the rotation shaft is fixedly connected with a rotation cage formed by end plates at the two ends and a plurality of cross bars bridged between the end plates; each cross bar of the rotation cage is provided with a plurality of loading covers for loading filters; the loading cover comprises a housing, the outer end of which is open; the center of the inner end of the housing is fixedly connected with a ball valve; the valve cavity of the ball valve is communicated with the inner cavity of the housing through an air hole arranged in the center of the inner end of the housing; the housing is internally and fixedly connected with a rubber plug with grooves for holding the filters in the center; the center of the bottom wall of each groove is provided with a through hole for the connection end of the filter to be inserted in; and the ball valve is connected with an air supply hose, and the other end of the air supply hose is fixedly connected and communicated with the rotation shaft.

Description

technical field [0001] The invention belongs to the technical field of filter production equipment, in particular to a device for detecting the tightness of a gasoline filter. Background technique [0002] figure 1 The structure of the gasoline filter is shown, which can generally include a housing 1 with a built-in filter paper 4, and a lower connection terminal 5 is provided at the bottom center of the housing 1 to form a dirty oil inlet for connecting external pipelines. 1 is provided with a top cover 3, and the center of the top cover 3 is provided with an upper connection terminal 2 to form a gasoline outlet. The connection strength and sealing performance between the upper cover 3 and the housing 1. After processing and molding, the tightness of the gasoline filter needs to be tested. Through reasonable testing methods, it is found that there are 2 upper connection terminals at the center of the upper cover 3, 5 lower connection terminals at the center of the bottom ...
