Large environment simulation test device for pipeline ball valve test

Abstract

The invention discloses a large outer load bending test device for pipeline ball valve test. The device comprises a pressure supply system, a data processing system, an environment simulation bin, a test lifting bench, a temperature sensor and a torque measuring device, wherein the test lifting bench is used for adjusting the height of a tested pipeline ball valve, and the temperature sensor is used for measuring high temperature and low temperature. The device has the advantages that the maximum pressure of the pressure supply system is 70Mpa; the maximum tension of a single double-function hydraulic fluid cylinder of the test lifting bench is 250T, the maximum travel is 2000mm, and the requirement of adjusting the heights of NPS2 to NPS60 pipeline ball valves is met; the environment simulation bin meets the temperature requirement of -50 DEG C to +93 DEG C, the size of a box is 210m<3>, and the test requirement of NPS2 to NPS60 and Class 150 to Class 2500 pipeline ball valves is met; the maximum measuring range of the torque measuring device is 600000N.m.

Description

technical field [0001] The invention relates to an environment simulation test device, in particular to a large-scale environment simulation test device for pipeline ball valve tests. Background technique [0002] In the construction of long-distance pipelines, the environment of pipeline ball valves is very harsh, from the Arctic Circle to the equator, from mountains to seabeds, from plateaus to deserts, across seismic zones, swamps, rivers, lakes, hillsides, etc. Some are erected and some are directly buried underground. They are remotely operated in the field and difficult to maintain. They are reliable and sealed within 30 years of service. Therefore, in the development process of pipeline ball valves, there are still many type tests. Although these tests are not included in the product standard API 6D, they are very important to verify the reliability, stability and applicability of the product to the working conditions of long-distance pipelines. . In 1971, the Unite...
