Valve high-temperature high-pressure environment vertical arrangement test system

Abstract

The invention provides a valve high-temperature high-pressure environment vertical arrangement test system, which can meet vertical installation test of a valve. The system comprises a gas source system, a filter system, a pressure booster system, a pressure stabilizing system, a pressure regulating system, a cooling system and a master measurement control system. A furnace platform is fixedly arranged on the ground of a ground pit; rails are paved on the ground of the ground pit; a furnace body is mounted on the rails through walking devices, and covers the furnace platform; and the inner space of the furnace body forms a test room. The furnace body is divided into a left furnace body and a right furnace body, which can move at the two sides of the furnace platform to realize open and close. The top portion of the furnace body is provided with a preformed hole. A motor actuating mechanism is vertically arranged, and is used for connecting and controlling a valve rod vertically extending out of the preformed hole. The left furnace body and the right furnace body are respectively provided with a circulating fan, a flow guiding device, an exhaust device and an air inlet device, wherein the circulating fans, the exhaust devices and the air inlet devices are communicated with the inner space of the furnace body. An electric heater device is mounted on the furnace body.

Description

technical field [0001] The invention relates to a vertical test system for a valve in a high temperature and high pressure environment. Background technique [0002] The valve life test refers to the cycle test of the valve under specific test conditions to investigate the change of various failure modes over time such as its life characteristics and failure rules, and to test for the rationality of valve structure design, sealing performance, processing quality, and material selection. Provide basic data for reliability design, prediction, and improvement of new product quality. [0003] The valve air tightness test mainly checks the internal leakage and external leakage of the valve. The internal leakage of the valve refers to the gap between the valve core and the valve body due to the erosion and wear of the medium, which is not tightly closed, and the medium can flow through. Leakage of the valve means that the seal between the valve and the connecting flange or conne...

Problems solved by technology

[0005] The applicant has Chinese patents with application numbers 201621184464.3 and 201610961033.1, which have realized the life test and air tightness test of high-temperature and high-pressure gas for valves. However, the high-temperature furnace design used in this patent technology has valves that are arranged in a horizontal position, that is, the motor actuator is arranged in a horizontal position. , which is inconsistent with the vertical arrangement of the valve in actual use; and the valve seal is easy to wear due to uneven force, resulting in leakage of the test working fluid
