Generally speaking, the price of China's exhaust valves is relatively stable. Although there is a slight increase and decrease every year, the range is very small. In the North China exhaust valve market, many companies have found that the profits are shoddy, seriously disrupting the exhaust valve market. The main problems in the exhaust valve market are as follows: 1. Some operators who purchase unnamed factories and print famous brands and certificates of well-known manufacturers cause serious damage to the reputation of qualified exhaust valve enterprises. Second, the venting of the exhaust valve, some operators through the re-painting of the exhaust valve after the second sale, bringing serious safety risks to the project quality.
With the transfer of oil development to inland oil fields and offshore oil fields, and the development of thermal power from 300,000 kilowatts or less to thermal power and hydropower and nuclear power, the performance and parameters of equipment should be changed accordingly. Urban construction systems generally use a large number of low-pressure exhaust valves, and the development of environmentally friendly and energy-saving, that is, the low-pressure iron gate valve used in the past has gradually turned to environmentally friendly rubber plate valves, balancing valves, metal sealing butterfly valves and mid-line sealing butterfly valves. Oil and gas transmission projects are developing in the direction of pipelines. From the perspective of energy conservation, it is necessary to develop steam traps and develop to high parameters of subcritical and supercritical.
The construction of the power station is going to be large-scale, so it is necessary to use a large-diameter and high-pressure sum, and also need to use a quick opening and closing exhaust valve. The needs of complete sets of projects have evolved from single varieties to multiple varieties and multiple specifications. The exhaust valves required for an engineering project are increasingly being provided by a single exhaust valve manufacturer.
