Description

technical field [0001] The invention relates to the technical field of valve testing equipment, and more particularly, to a multi-position wear simulation test device for wear-resistant valves. Background technique [0002] In the lock bucket system, because the wear-resistant valve is used in the slag collection and slag discharge cycle process with the characteristics of high temperature, high pressure and strong corrosion, the switching frequency is high, and it has tight sealing under high pressure conditions. Therefore, the wear-resistant valve must have perfect structural design, advanced manufacturing technology and equipment, and reasonable surface treatment technology to ensure that the wear-resistant valve has a long service life in high-strength and harsh working conditions. [0003] Although the operating conditions of the valve are very complicated, the existing valve standards usually only consider the operating pressure of the valve for the test of the valve, ...

AI Technical Summary

Problems solved by technology

[0003] Although the operating conditions of the valve are very complicated, the existing valve standards usually only consider the operating pressure of the valve in the test of the valve, and some standards also consider the operating temperature of the valve. For example, the high temperature valve standard requires the valve to be tested under high temperature conditions. However, it is only added to the existing valve test device that the high-temperature thermal cycle test device of the valve can be placed in it, and the test environment of the simulated high-temperature thermal state can be realized by heating the valve to be tested. Therefore, the high-temperature thermal state of the valve The dynamic cycle test device is a large heating furnace box, which is only used for single or multiple test valves to be tested, and the inlet and outlet devices used to connect with the valves to be tested are placed in the heating furnace box to prolong the service life. Therefore, when the valve is opened and closed, the temperature of the medium passing through it is still the room temperature outside, which not only reduces the accuracy of the test, but also takes away the heat in the furnace, so that a large amount of heat energy is wasted, and the heating For the application of the furnace box, the valve to be tested needs to be placed in it first, and then the heating is turned on. The test can only be started after the temperature in the heating furnace box reaches the test temperature, which greatly reduces the test efficiency.

[0004] In addition, the current valve standards generally only use clean test media for valve tests, such as water, air, nitrogen, helium, etc. Since the existing valve standards do not stipulate the test of valves simulating actual operating conditions, it has passed the standard. It is difficult to ensure that the tested valves meet the requirements of actual use
