Problems solved by technology

[0004] However, the existing solution to the internal leakage of valves is only to take remedial measures after the internal leakage occurs. This method cannot detect the internal leakage of high-end valves in time, so it cannot effectively reduce the damage caused by internal leakage of high-end valves. loss

Embodiment Construction

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0033] Such as figure 1 As shown, a high-end valve testing method provided by the embodiment of the present invention includes:

[0034] S101. Open the first on-off valve and close the second on-off valve.

[0035] In order to ensure safe operation, high-end valves often have two on-off valves. When the closing operation is performed,...

Abstract

The invention discloses an intelligent high-end valve and a method and a device for testing the same. The high-end valves are detected by temperature sensors correspondingly. If the valve is in leakage, over-high temperature signals can be acquired, and thus, users can judge which valves are in leakage. By the method and the device, the valves can be detected in advance, leakage can be found out quickly once the valves are in leakage, and accordingly loss caused by leakage can be reduced.

Description

technical field [0001] The invention relates to the technical field of high-end valves, in particular to a testing method and device for high-end valves and an intelligent high-end valve. Background technique [0002] With the rapid growth of my country's productivity, the energy needed for economic development is becoming more and more scarce. Although solar power, wind power and other green energy sources provide more and more electricity, thermal power is still the main source of electricity in my country. In the field of thermal power generation, energy-saving and environmentally friendly 600MW, 1000MW subcritical and supercritical thermal power units have become the main units. In these units, a large number of high-end valves are used. [0003] These high-end valves play an important role in the operation of the generator set. In order to ensure the safety of operation, the high-end valves often have two on-off valves. However, due to technological level, daily loss ...
