AI Technical Summary

Technical Problem

Existing integrated valve testing equipment has poor fixation of the valve body under test during use, which makes it easy for deviations to occur during the test. Moreover, the split design of the equipment results in a large size, cumbersome operation, low testing efficiency, and the independent operation of multiple modules can easily lead to data dispersion and poor coordination.

Method used

A comprehensive valve life testing device was designed, comprising a gantry frame, a base, a fixing component, and a testing component. The device achieves stable fixation and accurate testing of the valve body through the clamping unit of the fixing component and the displacement unit of the testing component. Combined with a laser displacement sensor to record the axial elongation of the valve stem, it simulates pipeline vibration to detect wear of the sealing surface and attenuation of opening and closing torque.

Benefits of technology

It achieves stable fixation of the valve body, avoids deviations during the test, has a small overall size and is easy to operate, improves testing efficiency, and has accurate data recording and good coordination.

Abstract

This utility model discloses a comprehensive valve life testing device, belonging to the technical field of valve testing devices. The device includes a gantry frame, a base at the bottom of the gantry frame, a valve body to be tested at the top of the base, and a first half-box and a second half-box positioned opposite each other on the outside of the valve body. A fixing component is located on the top of the base, and a testing component is located on the top of the gantry frame. The fixing component includes a fixed shell fixedly connected to the top edge of the base, a first clamping unit located on the side of the fixed shell, and a second clamping unit positioned opposite each other on the outside of the fixed shell. The testing component includes a movable frame mounted on the top of the gantry frame, a sliding plate located on the top of the movable frame, a first displacement unit located between the sliding plate and the movable frame, and a commutator located on the side of the sliding plate. A second displacement unit is located between the movable frame and the gantry frame. This utility model, through its fixing and testing components, offers convenient operation and improves testing efficiency.
