A leak detection device for a one-way valve

Abstract

The invention relates to a sealing performance detecting device of a single-way valve. The sealing performance detecting device comprises an operation platform, a feeding mechanism, a feeding block, a first air cylinder, a water tank, a control panel and an electric control box. The feeding block is fixed on the operation platform. A clamping groove is formed in the upper surface of the feeding block. The first air cylinder is fixed on the operation platform through a supporting column. The first air cylinder is placed above one end of the feeding block. The lower end of a first piston rod of the first air cylinder is connected with a pressing block. A hole which is matched with a gas communication end of the single-way valve is formed in the bottom of the pressing block. The pressing block is connected with the water tank through a pipeline. A gas through hole is formed in the upper portion of the feeding block. The bottom of the feeding block is connected with a gas pipeline. The feeding mechanism comprises a feeding barrel and a second air cylinder. The feeding barrel is fixed on the operation platform, a blocking ring is arranged at the top of the feeding barrel, a notch is formed in the blocking ring, a track is arranged at the notch in a connecting mode, and the tail end of the track is connected into the clamping groove. The sealing performance detecting device is simple in structure and can save labor force effectively, and detecting efficiency is high.

Description

technical field

[0001] The invention belongs to the technical field of one-way valve detection equipment, and in particular relates to a sealing performance detection device of a one-way valve. Background technique

[0002] One-way valve is also called check valve or check valve. Used in hydraulic systems to prevent reverse flow of oil flow, or used in pneumatic systems to prevent reverse flow of compressed air. Due to the special working environment of the check valve, the general check valve is required to have high sealing performance, and there are many factors affecting the sealing performance of the check valve, which are also closely related to the production process of the check valve.

[0003] At present, the sealing performance of check valves is usually tested manually by workers. The efficiency of the detection is low, the effect is poor, the labor is seriously wasted, and the production efficiency of the factory is affected, and the production cost is increased...
