Product Description

Butterfly valve is a commonly used small and medium-sized Control Valve, widely used in various industrial pipelines, petroleum, chemical, food, medicine, aviation, machinery and other fields due to its unique structure, light weight, easy operation, good sealing, strong valve flow capacity, and convenient installation.

1、 On the Structure of Butterfly Valves in Universal Valve

The butterfly valve uses a "gate" as the opening and closing element, which can control the on/off and flow of the pipeline through rotation, and has the characteristics of simplicity and practicality. The sealing surface of the gate is in contact with the fluid inside the pipeline, and its material and shape directly affect the sealing and flow capacity of the valve. Modern butterfly valves often use gate plates made of metal and rubber materials, which are applied to different working conditions. For example, rubber rams are suitable for low pressure and highly corrosive media, while metal rams are suitable for high-speed, high-pressure, and high-temperature conditions. To ensure the sealing performance of butterfly valves, the size of the gate must match the diameter of the pipeline, otherwise problems such as air and liquid leakage may occur during use.

The operation methods of butterfly valves are diverse, generally divided into manual, electric, pneumatic, hydraulic, etc. In terms of manual operation, the lever length of the butterfly valve should be moderate, the operating force should be light, and easy to control. In terms of electric and pneumatic operation, butterfly valves often use manual spring return mechanisms to ensure that they can still automatically close in the event of sudden power outages or other abnormal situations.

2、 Application of Butterfly Valves

Butterfly valves are widely used in various industrial pipelines, petroleum, chemical, food, medicine, aviation, machinery and other fields. Specifically, butterfly valves are suitable for the following situations:

1. Flow regulation

Butterfly valves are suitable for flow regulation. Under certain working conditions, the angle of the gate can be used to control the on-off and flow of the medium.

2. Cut-off control

When it is necessary to close or fully open the pipeline, a butterfly valve can be used as the cut-off control component of the pipeline.

3. Voltage regulation control

When it is necessary to regulate the pressure of the fluid in the pipeline, a butterfly valve can be used as a regulating element. Compared to traditional regulating valves, butterfly valves have higher flow capacity and can achieve both flow regulation and pressure control.

4. Special medium control

Butterfly valves also have strong advantages in controlling special media. For example, in industries such as food, medicine, and paper making, the medium requires slight pollution or even no pollution. Butterfly valves have strong sealing properties and will not cause secondary pollution to the medium. In addition, butterfly valves are suitable for medium control in special working conditions such as high temperature, high pressure, and high speed.
