How to choose the right hydraulic butterfly valve?
Hydraulic butterfly valve is a common fluid control valve, widely used in petroleum, chemical, electric power, water supply and other industries. Choosing the right hydraulic butterfly valve can improve the work efficiency and reduce the cost. This article will describe how to choose a suitable hydraulic butterfly valve.
First, understand the pipeline system
Before choosing the right hydraulic butterfly valve, it is necessary to understand the nature and characteristics of the piping system. First of all, it is necessary to understand the pressure, temperature, flow and other parameters of the pipeline in order to choose the appropriate valve material, size and valve type.
2. Determine the fluid medium
The choice of hydraulic butterfly valve should also consider the nature of the fluid medium, such as whether it has corrosive, viscous, temperature and other parameters. Different fluid media will have different requirements on the material and sealing of the valve, so it is necessary to choose according to the actual situation.
Third, choose the appropriate valve material
The material of the hydraulic butterfly valve mainly involves the valve body, sealing pair and pipeline connection. Usually used steel, cast iron, stainless steel and other materials. Choosing the right valve material can ensure the stability and durability of the valve in the specific working environment, thus extending the service life of the valve.
4. Select the appropriate valve type
There are three types of hydraulic butterfly valves: single eccentric, double eccentric and triple eccentric. Single eccentric valve suitable for low pressure, low flow fluid medium; Double eccentric valve is suitable for medium and high pressure and high flow medium; Three eccentric valves are suitable for high pressure, high temperature and corrosive media. Therefore, the choice of the appropriate type of hydraulic butterfly valve can be selected according to the actual working environment needs.
5, determine the inertia and flow requirements
When selecting a hydraulic butterfly valve, it is necessary to determine its inertia and flow requirements. According to the inertia and flow of the valve, the appropriate control instrument and pressure relief device are selected to ensure the stability and safety of the pipeline system.
The above are several aspects of choosing a suitable hydraulic butterfly valve. Of course, when choosing a hydraulic butterfly valve, other factors need to be considered, such as tightness, process requirements, and so on. In general, the correct selection of hydraulic butterfly valves can ensure the efficient and stable operation of the piping system and reduce costs.
