It is a well-known fact that aircraft have become an indispensable means of transport for mankind today. How to improve the safety of aircraft take-off and landing is an issue worth our consideration. Aircraft take-off and landing the greatest danger, deviation, flat tire or even run out of the runway occurs when the pressure servo valve available, just to improve the safety of this drawback. The new pressure servo valve using jet tube form, anti-oil pollution ability, very "resistant", "dirt", long-term use, low failure rate, high safety factor. To break the foreign technology blockade and monopoly, to achieve jet pressure servo valve localization, to fill the blanks of this domestic aircraft components. Although the pressure servo valve looks like a small cup size, but it is the aircraft control brake hydraulic high precision equipment, priced at 10,000 yuan to tens of thousands of dollars. China Shipbuilding Heavy Industries Institute 704 in Shanghai independent research and development of aircraft brakes multi-type pressure servo valve, a few days ago equipped with different domestic models successfully God, fully verified our country has mastered this jet pressure servo valve advanced technology, changed the previous Aircraft brake relies on complete sets of imported situation. It was revealed that domestic jet pressure servo valve can gradually replace the nozzle baffle of the previous generation of products, and at least 50% cost advantage to replace imports. In the past, nozzle baffle-type pressure servo valve is the mainstream of aircraft brake equipment, but it is precisely the brake system "weakness." Nozzle baffle pressure servo valve is the most afraid of hydraulic oil dirty with a long time, once the fluid cleanliness drops, the nozzle is blocked, resulting in braking is not working, or even lead to accidents. Therefore, this traditional form of pressure servo valve requires frequent inspection, cleaning and even valve changeover, resulting in high maintenance and repair costs. This shows that the pressure servo valve for aircraft takeoff and landing is crucial, for the aircraft taking off and landing add safety factor. Thus, to escort the aircraft take off and land.
