What is the strength function of the instrument valve
The strength function of instrument valve refers to the ability of valve to accept medium pressure. The valve is a mechanical product accepting internal pressure, so it is necessary to meet the strength and stiffness to ensure long-term use without cracking or deformation.
After the medium flows through the valve, there will be pressure loss (that is, the pressure difference between the front and the back of the valve), that is, the valve has a certain resistance to the activity of the medium, and the medium will consume a certain amount of energy to overcome the resistance of the valve. From the perspective of energy conservation, when planning and making valves, the resistance of the valve to the moving medium should be reduced as much as possible.
Action function action sensitivity and reliability refers to the sensitivity of the valve to make corresponding response to the change of medium parameters. As for the throttle valve, pressure reducing valve, regulating valve and other valves used to regulate the medium parameters, as well as the safety valve, steam trap and other valves with specific functions, their function sensitivity and reliability are very important technical function indicators.
The sealing function of the instrument valve refers to the ability of the sealing parts of the valve to block the leakage of the medium, which is the main technical function index of the valve.
