Description

Technical Field

[0001] The utility model relates to the technical field of instrumentation equipment, in particular to an anti-blocking V-cone flowmeter. Background Art

[0002] The V-cone flowmeter is a flow measuring instrument, which is mainly used for flow measurement of liquid, gas and steam. The V-cone flowmeter is divided into two forms: integrated and split. It uses the throttling effect of the V-cone in the flow field to measure the flow by detecting the upstream and downstream pressure difference. Compared with ordinary throttling parts, it changes the throttling layout from center hole throttling to annular throttling. The V-cone flowmeter is composed of a V-cone block and a differential pressure transmitter. Since the gap between the V-cone block inside the V-cone flowmeter and the inner wall of the shell is small, it is easy to cause the V-cone flowmeter to be blocked at the large diameter of the V-cone block when it is in use, which is not convenient to use.

[0003] In the existing anti-blocking V-cone flowmeter (an anti-blocking V-cone flowmeter with application number 202222160474.5), the anti-blocking mechanism drives the gear to rotate through a motor to rotate the thread to dredge the V-cone flowmeter, but the rotating thread cannot move forward and backward, thereby failing to dredge the connection between the flowmeter casing and the cone in a mobile manner, causing the V-cone flowmeter casing to be blocked, affecting the flow measurement of the medium by the V-cone flowmeter.

[0007] Furthermore, the driving mechanism includes a rotating driving member, a first gear and a second gear, the second gear is meshingly connected to the first gear, and the first gear is fixedly connected to an output end on the rotating driving member, so that the rotating driving member drives the rotating plate on which the second gear is fixedly installed to rotate.

[0008] Furthermore, the dredging mechanism includes the rotating plate and the dredging plate, an annular rotating groove is provided inside the outer shell, the rotating plate is movably installed in the rotating groove, and the dredging plate is movably installed inside the rotating plate, so that the dredging plate is driven to rotate when the rotating plate rotates, so as to dredge the blockage in the gap between the outer shell and the cone.

[0009] Furthermore, two corresponding movable grooves are provided inside the rotating plate, and two sliders are provided on the outside of the dredging plate, so that each slider can move along each movable groove, so that the dredging plate fixed with the slider can move along the inside of the outer shell, so that the dredging plate can dredge the blockage in the gap between the outer shell and the cone.
