Problems solved by technology
Although in recent years, with the products of major foreign ultrasonic flowmeter production companies entering the Chinese market one after another, it has also driven the development of domestic ultrasonic flow measurement research, but generally speaking, the existing domestic ultrasonic flowmeter technology is in terms of accuracy and stability. There is still a big gap with the international advanced level in terms of reliability and consistency

The invention relates to a connecting seat for an ultrasonic flowmeter. The connecting seat comprises a signal cable, a conductive wafer, an insulating sleeve, a connecting seat I, a spring, a connecting seat II, a sealing sleeve, a gasket and a sealing plug; the conductive wafer is arranged in a groove of the insulating sleeve; the boss of the insulating sleeve is arranged in the slim hole of theconnecting seat I; the connecting seat I is arranged at the lower end of the connecting seat II; the spring is arranged between the connecting seat I and the connecting seat II; the sealing sleeve and the sealing plug are arranged in the stepped hole II of the connecting seat II, the sealing sleeve is arranged above the connecting seat II, and the sealing plug is arranged above the sealing sleeve; and the gasket is arranged between the sealing sleeve and the sealing plug. The connecting seat and an ultrasonic flowmeter probe seat are used in cooperation to guide out signals, a cable core of the signal cable conducts out ultrasonic signals through a metal sheet in the contact probe seat, an inner hole of the connecting seat I is coated with a shielding layer of the signal cable, a ground wire of the signal cable is connected with a pipeline through the connecting seat I, the spring and the connecting seat II, and the ground end is consistent. Signal accuracy is improved.
Description
technical field [0001] The invention relates to an ultrasonic flowmeter, in particular to a connection seat for the ultrasonic flowmeter. Background technique [0002] Ultrasonic flowmeter is an important industrial instrument. The research on ultrasonic flowmeters in my country started relatively late, and the research and production of ultrasonic flowmeters are still relatively backward. Although in recent years, with the products of major foreign ultrasonic flowmeter production companies entering the Chinese market one after another, it has also driven the development of domestic ultrasonic flow measurement research, but generally speaking, the existing domestic ultrasonic flowmeter technology is in terms of accuracy and stability. , Reliability and consistency still have a big gap with the international advanced level. In the domestic market, especially in high-end applications, high-precision ultrasonic flowmeters are still dominated by foreign brands, such as Aichi i...
