1. China gate valve structure

The China gate valve is mainly composed of a valve body, a hydraulic device, a hydraulic station, and an electric control box. The dimensions of the connection gate are shown in the attached drawings.

2, China gate valve features

(1) The China gate valve uses an accumulator to replace the heavy hammer in the heavy hammer type hydraulic control butterfly valve, and changes the potential energy of the weight hammer into fluid pressure. The design is reasonable, the volume is small, the weight is light, the structure is simple, and the functions are complete. Flexible and reliable action, beautiful appearance, energy saving, easy maintenance and other advantages.

(2) The China gate valve has a relatively complete hydraulic system and a reliable electrical control system. It can be operated on site or remotely. It is easy to operate and use.

China gate valve The hydraulic station and the electrical control box are separated from the valve body and installed; the valve body can be arranged horizontally or vertically. Selectable on-site conditions.

3, China gate valve switching characteristics

The valve adopts a metal hard seal structure, and the valve is rotated by 90° through the crankshaft driven by the oil cylinder and the valve shaft to realize the opening and closing of the valve. Adjust the closing parameters of the valve by adjusting the adjusting plugs on the cylinder. The adjusting method is shown in Table 1 for debugging. The valve is opened and the fast and slow closing time is set at the factory. If the contract agreement requires the order to be executed according to the user's requirements. . If the ordering user does not require it, the fast off time is adjusted to 5 seconds, the slow off time is adjusted to 15 seconds, and the fast/slow shutoff switching angle is set to fast off by 90°~25° and slow off by 25°~0°. The valve opening time is set within 30 to 60 seconds.
