Automatic no-water pressure tester

Abstract

The invention provides an automatic no-water pressure tester comprising a base which is provided with an intermittent rotating disc. The intermittent rotating disc is provided with multiple working positions under detection on which valves under detection are arranged. An elevating cylinder is correspondingly arranged above each working position under detection. The lower end part of the elevating cylinder is provided with a sensor monitoring device. The middle part of the intermittent rotating disc is provided with an air compressor air storage tank which is used for inflating to the valves under detection. The periphery of the intermittent rotating disc is provided with a material inlet set, a torsional force set and a material outlet set. The material inlet set, the torsional force set and the material outlet set are fixedly arranged on the base. The whole test process has no water so that the risk of rusting caused by water on the surface of the product can be avoided, the drying link of a drying device can also be omitted, the detection efficiency is greatly enhanced and input cost and labor cost are low; and the accuracy of the detection result is high and multiple valves can be simultaneously detected so that the automatic no-water pressure tester is suitable for detection of a large number of valves and the detection efficiency can be directly enhanced.

Description

technical field [0001] The invention belongs to the technical field of valve detection and relates to valve pressure test equipment, in particular to an automatic anhydrous pressure test machine. Background technique [0002] As we all know, there are quite a variety of valve varieties and specifications, from the simplest shut-off valve to various valves used in extremely complex automatic control systems, which can be used to control air, water, steam, various corrosive media, mud, oil, liquid, etc. Flow of various types of fluids such as metals and radioactive media. A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. A valve is a device that makes or stops the flow of media (liquid, gas, powder) in piping and equipment and controls its flow. The valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium, and has the functions of diversi...

Problems solved by technology

[0004] At present, in the market, water filling is usually used to test whether the valve is leaking. The most basic way to judge is to see if the valve has bubbles. However, this detection method has the following defects: due to the water filling test, the product will rust , leading to rust on the surface, it must be dried with the help of a drying device, which not only increases the process, affects the efficiency of detection, but also increases the investment in equipment, which increases the cost pressure on the enterprise; There is some misjudgment of water leakage, resulting in low detection accuracy
