Bevel gear gate valve, also known as gate valve or gate valve, is a widely used valve. It controls the opening and closing of the valve through the lifting and lowering of the gate, which is perpendicular to the fluid direction. Changing the relative position between the gate and the valve seat can change the channel size.

Gate valves have the following advantages:

1. The fluid resistance is small, and the sealing surface is less susceptible to medium brushing and erosion.

2. Opening and closing are more effortless.

3. The flow direction of the medium is unrestricted, does not disturb flow, and does not reduce pressure.

永盛彩4. Simple form, short structural length, good manufacturing process, and wide application range.

1、 Purpose:

Install water and steam pipelines as opening and closing devices.

2、 Structure description:

1. The two ends of the branch pipe are connected by welding, and the opening and closing of the valve are controlled by a gear transmission device.

永盛彩2. The valve closure is mainly achieved through the bevel gear mechanism on the valve cover and the adjustable double single gate, universal top, clamp ring, etc., which are guided by the valve body for lifting and lowering movement.

3. The sealing surface of the valve seat is made of cobalt based hard alloy overlay welding, with good wear resistance and scratch resistance.

永盛彩4. The surface of the valve stem is treated with corrosion-resistant nitriding, which has good corrosion resistance and scratch resistance.

永盛彩5. The pressure self tightening sealing mechanism uses medium pressure to compress the wedge-shaped sealing ring to achieve sealing. The higher the medium pressure, the better the sealing performance.

3、 Installation instructions: 1 When installing the valve, it must be installed vertically on a horizontal pipeline, and the medium can enter from either side. Only after the pipeline is flushed clean can the valve be installed. 2. When using this valve, it should be fully open or fully closed and cannot be used as a regulating valve.
