Forged steel ball valve is a commonly used valve, widely used in petroleum, chemical, natural gas, electric power and other industries. It has the advantages of simple structure, reliable sealing and flexible operation, so it is very popular. However, in order to ensure the normal operation of the forged steel ball valve, we need to select the appropriate ball valve according to the medium, pressure, temperature and other parameters, and install the ball valve correctly. This article will introduce the selection and installation method of forged steel ball valve.
Selection
1. Select according to media
The medium is one of the important factors in choosing a forged steel ball valve. Different media have different requirements for ball valve materials, sealing materials, structures, etc. For example, for corrosive media, corrosion-resistant materials should be selected, such as stainless steel, alloy steel, etc.; for high-temperature media, materials that can withstand high temperatures should be selected, such as cast steel, alloy steel, etc.
2. Select according to pressure
Pressure is another important factor in choosing a forged steel ball valve. Different pressures have different requirements on the structure and sealing performance of ball valves. Generally speaking, the nominal pressure of the ball valve should be greater than or equal to the maximum working pressure of the pipeline. If the pressure is high, high-strength materials should be selected, such as alloy steel.
3. Select according to temperature
Temperature is also one of the important factors in selecting forged steel ball valve. Different temperatures have different requirements for ball valve materials, sealing materials, structures, etc. Generally speaking, the nominal temperature of the ball valve should be greater than or equal to the maximum operating temperature of the pipeline. If the temperature is higher, high-temperature materials should be selected, such as cast steel, alloy steel, etc.
Installation
1. Installation location
The forged steel ball valve should be installed in a location that is easy to operate and maintain. At the same time, the installation position of the ball valve should take into account the flow direction of the medium and the layout of the pipeline to ensure smooth flow of the medium.
2. Installation method
(1) The installation of the ball valve should be carried out after the pipeline installation is completed. Before installation, check whether the appearance and internal structure of the ball valve are intact, and whether the sealing performance of the valve is good.
(2) The installation of the ball valve should be carried out according to the structure of the ball valve and the layout of the pipeline. Generally speaking, the inlet and outlet of the ball valve should correspond to the inlet and outlet of the pipe.
(3) When installing the ball valve, attention should be paid to the direction and position of the valve. The ball of the ball valve should be consistent with the flow direction of the pipe to ensure smooth flow of the medium.
(4) When installing the ball valve, attention should be paid to the sealing performance of the valve. Before installation, check whether the sealing surface and gasket of the valve are intact, and install the gasket correctly.
(5) When installing the ball valve, attention should be paid to the fixation of the valve. The fixation of the ball valve should be firm and reliable to ensure the normal operation of the valve.
