As the preferred scheme of the present invention, the graphite pads side elevation is T-shaped structure, and the mounting groove is step
Mounting groove, the piezoelectric probe are passed by the graphite pads interstitial hole, the piezoelectric probe when with body fits, side wall not with
Body contacts.
As the preferred scheme of the present invention, the piezoelectric patches of the piezoelectric probe including bottom and the piezoelectric patches top it is interior
Electrode, the bottom of interior electrode and the piezoelectric patches combination are socketed with external electrode, and the inner and outer electrodes are connected to lead respectively.
As the preferred scheme of the present invention, impact output voltage of the piezoelectric probe per 1Kg/m is less than 50V；It is total equivalent
Electric capacity is less than 3000PF.
As the preferred scheme of the present invention, the adpting flange is fixed on the body upper surface, the adpting flange
Top is provided with spring washer, and the spring washer is loop configuration, and it is placed in the middle part of the piezoelectric probe.
As the preferred scheme of the present invention, screw is provided with above the spring washer.
As the preferred scheme of the present invention, the graphite pads vertical portion is tied with wire.
Beneficial effect
The present invention proposes a kind of flux of vortex street part, including the connecting rod above body and body, the body and company
The coupling part of extension bar is provided with installation position, and a piezoelectric probe is installed in the installation position, and the coupling part includes connection
Flange, the adpting flange bottom are provided with graphite pads, and the body upper part is provided with mounting groove, and the graphite pads are installed on the peace
In tankage, through hole is provided with the middle part of graphite pads and adpting flange, forms a part for installation position.This product is by graphite pads, effectively
The conduction of temperature is reduced, prevents flowmeter bodies from reducing sensitivity because temperature is too high.
