AI Technical Summary

Technical Problem

Existing water pressure testing equipment is cumbersome to operate, making it difficult to adapt to large-scale full inspection operations, and poses a risk of iron contamination, thus failing to meet the usage requirements of nuclear power products.

Method used

Design a water pressure high-pressure testing device for instrument valves, integrated on a workbench frame. Utilize a ball valve to control the drive air source switch, and a pressure regulating valve to adjust the air source pressure. Combined with a three-way body and an instrument valve pressure testing clamping device, rapid positioning and clamping are achieved, and iron contamination is avoided through stainless steel piping.

Benefits of technology

Simplify operating procedures, improve production efficiency, ensure testing accuracy, avoid iron contamination, reduce maintenance costs, adapt to the needs of different production sites, and achieve environmentally friendly and efficient full inspection operations.

Abstract

This utility model discloses a high-pressure water pressure testing device for instrument valve bodies, belonging to the field of valve body testing technology. It includes a workbench frame, on which are mounted an air source filter, a ball valve, a pneumatic booster pump, a high-pressure needle valve, an output pressure gauge, a pressure relief valve, and a three-way valve body. The pressure relief valve is connected to a water tank. The ball valve controls the on / off switch of the driving air source. The three-way valve body is connected to an instrument valve pressure testing clamping device via a high-pressure hose. All components are integrated on the workbench frame. The ball valve controls the on / off switch of the driving air source, and the pressure regulating valve adjusts the driving air source pressure, thereby controlling the output pressure of the booster pump. Simultaneously, the three-way valve body cooperates with the instrument valve pressure testing clamping device to achieve rapid positioning and clamping, greatly simplifying the operation process, facilitating full inspection of instrument valve bodies, effectively improving production efficiency, meeting production needs, and solving the problem of traditional old-style electric pressure testing pump devices being cumbersome to operate and unsuitable for large-scale full inspection operations.
