Description
Technical Field
The invention belongs to the technical field of metering instruments, and relates to a flowmeter, in particular to a flowmeter with any installation angle.
Background
The float flowmeter is widely applied to the measurement of various fluid forces, the float flowmeter is connected in series in a pipeline, a float in the pipeline moves upwards when the flow is increased, and conversely, the float moves downwards when the flow is reduced. Thus, the amount of flow in the pipe can be measured by measuring the height of the float. The flowmeter does not use a power supply and has the characteristics of simple structure, good safety and the like. Because the gravity of the float is vertically downward, the existing flowmeter can only be vertically installed in a pipeline, and the measurement accuracy of the existing flowmeter is influenced. Meanwhile, the float of the flowmeter only plays a role in measuring the flow, and the adjustment of the flow is realized by rotating a knob of the flowmeter to control the conduction caliber of the pipeline, as shown in fig. 1, wherein an arrow in the figure is the flow direction of the fluid.

The flow regulating cavity is a taper cavity coaxial with the flowmeter seat, the opening of the taper bottom is arranged on the bottom surface of the flowmeter seat, and a flow control ball is arranged in the flow regulating cavity.
The flow regulating cavity is sealed by a front cover, and the flow control cavity is sealed by a rear cover.
The front cover is provided with a fluid outlet channel, the side wall of the flowmeter seat is provided with a fluid inlet channel at the position close to the conical top of the flow regulating cavity, and the flow regulating cavity is communicated with the outside through the fluid outlet channel and the fluid inlet channel.
The flow meter seat is internally provided with a screwed pipe which is communicated with the flow regulating cavity and the flow control cavity along the axis, and the middle part of the screw rod is in threaded connection with the flow meter seat through the screwed pipe.
One end of the screw rod is fixedly connected with the flow control ball, the other end of the screw rod is fixedly connected with a magnetic steel seat arranged in the flow control cavity, rectangular magnetic steel is arranged on the magnetic steel seat, and the N pole and the S pole of the rectangular magnetic steel are respectively arranged on two sides of the axis of the flow meter seat.

The invention can accurately control and display the flow by using the magnetic induction to accurately control the position of the flow control ball through the flow adjusting ring. Because the position of the flow control ball is no longer determined by the combination of gravity and buoyancy of the fluid, the flowmeter can be installed at any angle, and the applicability is wider than that of a common float flowmeter. Because the flow control ball controls the position through the screw rod, the position is more accurate, the performance is more stable and reliable, and the sealing performance is better.

fig. 2 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 2, the flowmeter with any installation angle comprises a flowmeter base 1, a front cover 2 and a rear cover 3 which are arranged on the same axis.
The flowmeter seat 1 is cylindrical, and both ends of the flowmeter seat are respectively provided with a flow regulating cavity 4 and a flow control cavity 5. The flow regulating cavity 4 is a conical cavity coaxial with the flowmeter seat 1, and a flow control ball 6 is arranged in the flow regulating cavity 4. The front cover 2 seals one conical bottom surface of the flow regulating cavity 4, the front cover 2 is provided with a fluid outlet channel 7, the side wall of the flow meter seat 1 close to the conical top of the flow regulating cavity 4 is provided with a fluid inlet channel 8, and the flow regulating cavity 4 is communicated with the outside through the fluid outlet channel 7 and the fluid inlet channel 8. The flow regulating cavity 4 is communicated with the flow control cavity 5 through a threaded pipe 9, and the middle part of the screw rod 10 is in threaded connection with the flowmeter seat 1 through the threaded pipe 9. One end of the screw rod 10 is fixedly connected with a flow control ball 6 arranged in the flow regulating cavity 4, the other end of the screw rod is fixedly connected with a magnetic steel seat 11 arranged in the flow control cavity 5, rectangular magnetic steel 12 is arranged on the magnetic steel seat 11, and the N pole and the S pole of the rectangular magnetic steel 12 are respectively arranged on two sides of the central axis of the flow meter seat 1. The flow adjusting ring 13 sleeved outside the flow meter base 1 corresponds to the flow control cavity 5 in position, a magnetic steel pair 14 is arranged on the inner side of the flow adjusting ring 13, the circumferential positions of two magnetic steels forming the magnetic steel pair 14 are symmetrical, and the polarities of the two magnetic steels facing the circumferential center are opposite.
An observation window is arranged on the outer wall of the flowmeter seat 1 corresponding to the flow regulation cavity 4, and flow scales 15 are marked on the observation window.
For convenience of illustration, the flow meter is set to be horizontally disposed, as shown in fig. 2. The fluid outlet channel 7 and the fluid inlet channel 8 are respectively communicated with a pipeline, and fluid enters the flow regulating cavity 4 from the pipeline through the fluid inlet channel 8, flows out from the fluid outlet channel 7 and re-enters the pipeline, wherein arrows in fig. 2 indicate the flow direction of the fluid. When the flow is required to be adjusted, the flow adjusting ring 13 is rotated, the magnetic steel pair 14 of the flow adjusting ring drives the magnetic steel seat 11 to rotate through the rectangular magnetic steel 12, and then the screw rod 10 is driven to rotate, so that the position of the screw rod is changed, and the position of the flow control ball 6 at one end of the screw rod is also changed. The further to the left the flow control ball is positioned, the larger the bore through which fluid can pass and the greater the flow rate. Conversely, the further to the right the flow control ball is positioned, the smaller the bore through which fluid can pass and the smaller the flow rate. When the flow control ball is in close contact with the inner wall of the flow regulating chamber 4, the fluid is intercepted and the flow meter is in a closed state.
The flow control ball in the flowmeter provided by the invention looks similar to the floating ball in the float flowmeter, but the functions of the flow control ball and the floating ball are completely different. A floating ball in the float flowmeter floats under the action of fluid buoyancy, the larger the flow is, the higher the position of the float is, and the main function of the float flowmeter is to measure the flow. However, in the present invention, since the flow control ball is coupled with the lead screw, its position is not changed by the magnitude of the flow. In contrast, the position of the flow control ball determines the aperture through which the fluid can pass, i.e., its height determines the flow rate of the fluid flowing therethrough, and thus the flow control ball serves a dual function of both flow control and flow indication in the present invention.
From the above analysis, since the position of the flow control ball (equivalent to the float in the float flowmeter) in the present invention is no longer determined by the gravity and the buoyancy of the fluid, the flowmeter can be installed at any angle, not only vertically, but also horizontally, and also obliquely, and the applicability is wider than that of the ordinary float flowmeter. In addition, the position of the flow control ball is controlled by the lead screw, so that the position is more accurate, and the performance is more stable and reliable.
The front cover and the flowmeter seat as well as the rear cover and the flowmeter seat are fixedly connected in a sealing way, and the movable part for adjusting the flow is positioned in the flowmeter, so that the sealing problem is completely solved.
