Market prospect of high pressure flat gate valve
It is a high pressure slide valve. The closed part can be single nozzle or double nozzle, and the nozzle of expanding mechanism is controlled by medium pressure acting on floating nozzle or floating sheet. If the high pressure flat gate valve is a double gate flat valve, the spreading mechanism between the two gates can compensate for this pressure. High pressure flat gate valve has reasonable structure, reliable sealing and light operation. The sealing mask has corrosion resistance, wear resistance and corrosion resistance. The high-pressure flat gate valve is made of solid high-pressure flat valve alloy spray which can be used for throttling. The high-pressure flat gate valve adopts the packing structure with self sealing ability, which does not need regular adjustment. It is very light to open and has reliable sealing performance. The stuffing box is an auxiliary sealing fat injection structure with reliable sealing performance and zero leakage.
In China's current valve market, the high-pressure flat gate valve still needs to be imported, except that it has reached the acceptable level in the international market. The import and export of China's valve products has also increased, but there is still a big gap in technology compared with foreign manufacturers. In the future, the technology of high-pressure flat gate valve will become a bottleneck restricting the development of valve products in China.
The large diameter of high pressure flat gate valve is 5350 mm. In addition, according to the statistics of relevant departments, the annual turnover of valve market in China is as high as 50 billion yuan, of which more than 10 billion yuan market is occupied by foreign valve enterprises. High pressure flat gate valve is an indispensable fluid control equipment in petroleum, chemical industry, power station, long-distance pipeline, shipbuilding, nuclear industry, various low-temperature engineering, aerospace and marine oil extraction.
