How to achieve a high flow bidirectional hard seal butterfly valve?
Bidirectional hard sealed butterfly valves are a common valve equipment widely used in various industrial fields. With the development of industrialization and continuous technological progress, the requirements for bidirectional hard seal butterfly valves are also increasing, especially in high flow situations, the performance of bidirectional hard seal butterfly valves is particularly important. The wear-resistant ball valve manufacturer will analyze how to achieve high flow bidirectional hard seal butterfly valves from the principles, structures, and applications of bidirectional hard seal butterfly valves.
1、 The principle of bidirectional hard sealing butterfly valve
A bidirectional hard seal butterfly valve is a valve equipment that uses a butterfly plate as the main control component. Its principle is to open and close the valve by rotating the butterfly plate. When the valve needs to be opened, the butterfly plate is rotated to the horizontal direction, and the medium can flow through the channel of the valve; When the valve needs to be closed, the butterfly plate is rotated to the vertical direction, and the medium cannot pass through the channel and is cut off by the valve. The characteristic of a bidirectional hard sealed butterfly valve is its simple structure, easy opening and closing, and easy realization of fully open and fully closed states.
2、 Structure of Bidirectional Hard Seal Butterfly Valve
The main structures of bidirectional hard seal butterfly valves include:
1. Valve body: Consisting of a valve cover, valve seat, and butterfly plate, the valve cover and valve seat are hemispherical in shape, which can effectively reduce the erosion of the medium on the valve. The valve seat also has a fireproof effect; The butterfly plate is the control component of the valve, which can achieve the opening and closing of the valve.
2. Drive device: used to control the opening and closing of the butterfly plate, mainly including manual, hydraulic, electric, pneumatic and other methods.
3. Seals: mainly including valve cover seals, valve seat seals, and butterfly plate seals, with sealing surfaces usually made of rubber or other polymer materials.
4. Accessories: including positioning pins, check devices, shock absorbers, etc.

3、 Implementation of High Flow Bidirectional Hard Seal Butterfly Valve
For bidirectional hard sealed butterfly valves with large flow rates, the implementation requires optimization and improvement of the valve structure and materials to achieve more reliable and effective control.
1. Structural optimization
To achieve a bidirectional hard seal butterfly valve with high flow rate, it is necessary to optimize the valve body structure. The use of high-pressure and low-power opening methods can reduce the difficulty of valve operation and also broaden the flow range of the valve. In addition, a widening device can be installed in the valve body to expand the flow area of the fluid, thereby increasing the flow capacity and improving the flow capacity of the valve.
2. Material improvement
The material selection of bidirectional hard seal butterfly valves is also crucial. In the case of high flow rate, the frequency and pressure of valve use will also increase, so it is necessary to choose materials with high strength, high wear resistance, high temperature, and high corrosion performance. The use of materials such as hard alloy and stainless steel can significantly improve the service life of valves.
3. Control system upgrade
At present, with the popularization of intelligent technology, the upgrading of control systems has become a trend in the valve industry. The upgraded control system can more flexibly control the opening and closing of valves, better adapt to different working conditions, and can be monitored and controlled in real-time through technology such as the Internet of Things.
4、 Summary
Optimization of structure, improvement of materials, and upgrading of control systems are essential for achieving high flow bidirectional hard sealed butterfly valves. In the future, with the continuous innovation of industrial technology, the performance and application fields of bidirectional hard seal butterfly valves will also be continuously expanded and optimized, providing more reliable guarantees for the safety and effectiveness of industrial production.
