As an important industrial valve, the measurement and verification of its performance parameters are crucial for ensuring the normal operation of the valve and the stability of the system. Here are some common measuring tools used to measure the performance parameters of butterfly valves . 1. Pressure Measuring Tool for Butterfly Valve Pressure gauge: used to measure the pressure value of butterfly valves in working condition, including inlet pressure, outlet pressure, and the pressure bearing capacity of the valve. The pressure gauge can be directly installed on the valve or connected to the vicinity of the valve through a pipeline system for measurement. Pressure transmitter: converts pressure signals into electrical signals for remote transmission and recording, suitable for situations that require real-time monitoring and recording of pressure changes. Pressure sensor: a high-precision pressure measuring device that can provide more accurate pressure readings, commonly used for precision testing or calibration of butterfly valves. 2. Flow Measurement Tool for Butterfly Valves Flow meter: used to measure fluid flow through butterfly valves , including volumetric flow and mass flow. There are many types of flow meters, such as vortex flow meters, electromagnetic flow meters, ultrasonic flow meters, etc., and the appropriate type can be selected according to actual working conditions and measurement needs. Differential pressure flow measurement device: calculates flow by measuring the differential pressure before and after the butterfly valve , suitable for some specific measurement scenarios. 3. Temperature Measurement Tool for Butterfly Valves Temperature gauge: used to measure the temperature of butterfly valves and their surrounding environment, ensuring that the valve operates within the allowable temperature range. Common thermometers include glass thermometers, thermocouple thermometers, infrared thermometers, etc. Temperature controller: In situations where precise temperature control is required, a temperature controller can be used to monitor and regulate the temperature around the butterfly valve to ensure the normal operation of the valve and the stability of the system. 4. Sealing Testing Tool for Butterfly Valves Leak detector: used to test the sealing performance of butterfly valves in the closed state, including gas leak detectors and liquid leak detectors. These devices can accurately detect tiny leakage points, ensuring that the sealing performance of the valve meets the requirements. Bubble test method: a simple and effective sealing test method that judges the sealing performance of butterfly valves by applying soapy water or other foaming agents on the sealing surface and observing whether bubbles are generated. 5. Special Testing Bench for Butterfly Valves Butterfly valve test bench: a comprehensive testing equipment that integrates mechanical, electrical, hydraulic, and hydraulic pressure supply devices into a circulating water system, suitable for testing the strength and sealing water pressure and air pressure of butterfly valves . The butterfly valve test bench can visually display whether there is any leakage or bubbles in the butterfly valve chamber, and can perform torque and 90 degree opening and closing tests on the valve electric device. In summary, there are various types of tools for measuring the performance parameters of butterfly valves , including pressure measurement tools, flow measurement tools, temperature measurement tools, sealing testing tools, and specialized testing benches. When selecting and using these tools, reasonable selection and configuration should be made based on actual working conditions and measurement needs.
