Product Description

Product Description

Butterfly valve, also called flap valve, is a regulating valve with a simple structure that can be used for switching control of low-pressure pipeline media. The butterfly valve refers to a closing member (valve disc or butterfly plate) that is a disc and rotates around the valve axis to open and close. of a valve.

Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on pipelines. The butterfly valve opening and closing part is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.

Working principle

Butterfly valve is a valve that uses a disc-type opening and closing part to rotate back and forth about 90° to open, close or adjust the flow of the medium. Butterfly valves not only have simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and rapid operation, but also have good flow regulation function and closing sealing characteristics at the same time. They are the latest development in the past ten years. One of the fastest valve varieties. Butterfly valves are widely used. The variety and quantity of its use are still expanding, and are developing towards high temperature, high pressure, large diameter, high sealing, long life, excellent regulating characteristics, and multi-function in one valve. Its reliability and other performance indicators have reached a high level.
 

It is mainly composed of valve body, valve stem, butterfly plate and sealing ring. The valve body is cylindrical, with short axial length and built-in butterfly plate.
 

Features

1. The butterfly valve has the characteristics of simple structure, small size, light weight, low material consumption, small installation size, rapid switching, 90° reciprocating rotation, and small driving torque. It is used to cut off, connect, and regulate the medium in the pipeline. Has good fluid control characteristics and shut-off sealing performance.

2. The butterfly valve can transport mud and minimize the accumulation of liquid at the pipe mouth. At low pressure, a good seal can be achieved. Good adjustment performance.

3. The streamlined design of the butterfly plate reduces fluid resistance loss, making it an energy-saving product.

4. The valve stem is a through-stem structure. After quenching and tempering treatment, it has good comprehensive mechanical properties, corrosion resistance, and scratch resistance. When the butterfly valve opens and closes, the valve stem only rotates and does not move up and down. The packing of the valve stem is not easily damaged and the sealing is reliable. It is fixed with the taper pin of the butterfly plate, and the extended end is designed to prevent the valve stem from collapsing when the connection between the valve stem and the butterfly plate breaks accidentally.

5. The connection methods include flange connection, clamp connection, butt welding connection and lug clamp connection.

The driving forms include manual, worm gear transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.
