Founded in 2004, set up specialized equipment manufacturing, sales, professional technical advice and perfect after-sales service system in one of the modern enterprise, now has the domestic first-class production equipment, strict internal management, perfect quality control system, strong technical force, high quality staff team, build the company in recent years brilliant and successful....... When selecting the gate type, it is required to work in accordance with the characteristics of the gate, the span of the opening, the opening and closing force and the engineering cost. Which plane gate and radial gate is the most common type of door. Large and medium-sized top exposed and submerged gate most of the radial gate, high head deep hole gate is commonly used radial gate. When used as the gate of the accident and the maintenance gate, most of the plane gate. The gate and the accident gate are often set in front of the working gate. For high head discharging gate as often as hydrodynamic operation or partial opening should be managed to reduce the gate vibration and cavitation phenomenon, improve the gate hydraulic conditions and by different components considering dynamic effects, and the door body stiffness and dynamic characteristics of analysis and research.
