Description

Technical Field

[0001] The present invention relates to the technical field of flow meters, and specifically to a multi-tube balanced resonant flow meter. Background Art

[0002] In modern industry, various measuring instruments are required, and flow meters are a very common type of equipment. Flow meters usually measure various fluid flows to facilitate subsequent adjustment and analysis by operators. The uses of resonant flow meters are even more extensive. Their working principle is based on the Coriolis effect, and resonant measurement can directly measure the mass flow rate of fluid media, with high measurement accuracy, a wide range of measurable fluids, applicable to both liquids and gases. Therefore, they are often seen in modern industry.

[0003] Similarly, this type of flow meter is usually affected by many factors. For example, during measurement, the state of the damping oil will directly affect the measurement accuracy of the equipment, and during the measurement process, the flow stability of the fluid will also affect the detected value of the equipment. If backflow or inlet vortices occur, the resonant device will be affected, resulting in serious weakening or strengthening of the subsequent Coriolis phenomenon. These problems need to be urgently solved. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-tube balanced resonant flow meter to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: The resonant flowmeter includes a support housing. An inlet flange and an outlet flange are respectively arranged on both sides of the support housing. An inlet diverter is arranged inside the support housing. A plurality of diverter pipes are arranged on the side of the inlet diverter away from the inlet flange. An exciter is arranged on the support housing. A conduction sleeve is arranged on the exciter. The conduction sleeve is sleeved on each diverter pipe respectively. One end of each diverter pipe away from the inlet flange is communicated with the outlet flange respectively. An oil injection port and an oil return port are arranged on the support housing. A compensation pump is arranged on the oil injection port. The compensation pump is inductively connected to the inlet diverter through a wire. A check valve is arranged on the oil return port. A plurality of pickups are arranged inside the support housing. A display meter is arranged on the support housing. The display meter is electrically connected to the pickups through wires respectively. Before measurement, the resonant flowmeter needs to be installed on the pipeline to be measured first, and the resonator needs to be installed and the signal needs to be input. Then, wait for the fluid to be measured to enter the inlet flange and pass through the inlet diverter. The fluid will enter the diverter pipes respectively under the action of the inlet diverter. Then, start the exciter. The exciter will transfer the kinetic energy to the conduction sleeve, and the conduction sleeve will transfer the power to the diverter pipes. The flowing fluid in the diverter pipes will generate a reverse resistance after being impacted, and the reverse resistance force will be transferred to the rear diverter pipes. The diverter pipes will transfer the vibrating power to the inside of the support housing. The pickups inside the support housing will detect the vibration frequency and perform signal conversion, and transfer it to the display meter. The display meter will obtain the current flow value. In order to avoid the problem that the shock-absorbing fluid inside vibrates and the transmission is not timely, the compensation pump will compensate the shock-absorbing oil inside the support housing, and at the same time, the shock-absorbing oil inside can be replaced in time.

[0006] The inlet flange includes a connection port and a plurality of positioning ports. A sealing assembly is arranged on the connection port. A blocking rod is arranged inside the inlet flange. The blocking rod is rotatably connected to the inlet flange. Flow-following vanes are arranged on the blocking rod. A blocking ring is arranged on the blocking rod. A plurality of spoiler rods are arranged at one end of the blocking ring close to the inlet diverter. Each spoiler rod is in sliding contact with the inner wall of the inlet diverter respectively. When installing the inlet flange, install the inlet flange and the outlet flange on the pipeline in the correct direction, and then seal the connection through the sealing assembly. The connection port and the positioning ports play a role in supporting the installation. When the fluid enters the inlet flange, it drives the flow-following vanes on the blocking rod to rotate, and the blocking rod will rotate. The blocking rod will drive the fluid to rotate. At the same time, the spoiler rods will remove the impurities adhering to the inlet flange, which can not only evenly distribute the fluid into the diverter pipes, but also avoid the problem of unstable fluid flow caused by blockage.

[0007] The inlet diverter is provided with a flow guiding vane. Multiple flow guiding openings are arranged on the flow guiding vane, and each flow guiding opening is respectively communicated with a corresponding shunt pipe. A sealing ring is arranged on the flow guiding vane, and the sealing ring is connected to the inner wall of the inlet diverter. A flow guiding auxiliary vane is also arranged on the outlet flange. Multiple anti-reverse openings are arranged on the flow guiding auxiliary vane, and each anti-reverse opening is internally provided with an anti-reverse frame. Multiple anti-return pieces are rotatably connected to the anti-reverse frame. When the fluid flows through the flow guiding vane, the flow guiding vane will divert the fluid, reducing the vortex phenomenon that occurs after the fluid enters the shunt pipe. Subsequently, the fluid will pass through the anti-reverse frame. When the liquid is in the correct flow direction, the anti-return pieces will be in a closed state at this time. When the liquid has a reverse flow direction, the anti-return pieces will be in an unfolded state at this time, avoiding the problem of backflow generated during vibration.

[0008] A feedback rod is arranged between the flow guiding vane and the flow guiding auxiliary vane. The feedback rod passes through a conduction sleeve, and a feedback assembly is arranged on the feedback rod. The feedback assembly includes multiple feedback areas, which are evenly arranged on the feedback rod. A pressing piece and a pressing switch are respectively arranged in each feedback area. The pressing piece is in sliding contact with the pressing switch. A sealing diaphragm is arranged on the feedback area, and the sealing diaphragm and the feedback area form a sealed space. After the shunt pipe vibrates, it will cause the shock-absorbing oil to vibrate. This vibration will be sensed by the sealing diaphragm and squeeze the pressing piece, triggering the pressing switch. By judging the triggering conditions and the rebound conditions of the pressing switches in multiple areas, the current flow state of the shock-absorbing oil and whether the shock-absorbing oil inside is insufficient can be determined, and the triggering situation will be transmitted to the compensation pump. The compensation pump will supplement and replace the shock-absorbing oil inside according to the specific situation.

[0009] The feedback assembly further includes a trigger processing board. The trigger processing board is electrically connected to each pressing switch through a wire. The trigger processing board is arranged on the support housing and is electrically connected to the compensation pump through a wire. The trigger processing board will collect the trigger information, then convert it into an electrical signal and transmit it to the compensation pump. And a processing program is loaded in the trigger processing board. Through program analysis, it is determined whether the current situation requires the compensation pump to supply oil and change oil, so as to always ensure the stability and accuracy of power transmission.

[0010] Multiple through holes are arranged on the conduction sleeve. Each shunt pipe respectively passes through the corresponding through hole. A locking structure is arranged on each through hole. The locking structure includes a transmission sleeve and a transmission auxiliary sleeve. The transmission sleeve and the transmission auxiliary sleeve have the same structure. Installation grooves and installation buckles are respectively arranged on the transmission auxiliary sleeve and the transmission sleeve. The installation buckle on the transmission sleeve is buckled in the installation groove on the transmission auxiliary sleeve. The transmission sleeve and the transmission auxiliary sleeve are respectively in sliding connection with the through hole. The shunt pipe passes through the transmission sleeve and the transmission auxiliary sleeve, and then the shunt pipe is locked in the through hole through the installation buckle and the installation groove, so that the vibration transmission is more uniform and the problem of serious local damage to the shunt pipe is reduced.

[0011] A limiting slideway is arranged inside the support housing. The conduction sleeve is embedded in the limiting slideway and is slidably connected to the limiting slideway. A plurality of positioning screw holes are arranged on the conduction sleeve, and locking bolts are rotatably connected to the positioning screw holes. Each locking bolt abuts against the transfer sleeve and the transfer sub-sleeve. The vibration pickups are respectively arranged on both sides of the conduction sleeve. Through the limiting slideway, the exciter will drive the transfer sleeve to slide fully, avoiding the problem of deflection. At the same time, through the locking bolts, the positions of the conduction sleeve and the conduction sub-sleeve can be locked to adapt to various models of shunt pipes. The vibration pickups on both sides correct the fluid after resonance and the fluid before resonance, making the data more accurate.

[0012] A plurality of layer sieve plates are arranged inside the support housing. The distance between adjacent layer sieve plates is equal. Conduction blocks are respectively arranged on each layer sieve plate. Heat dissipation plates are respectively arranged between adjacent layer sieve plates. Conduction grooves are arranged on the heat dissipation plates. The conduction blocks are embedded in the conduction grooves on the heat dissipation plates. The fluid to be measured usually has a certain amount of heat, and the existence of heat usually affects the transfer performance of the shock-absorbing oil. At the same time, under long-term vibration, the shock-absorbing oil will also generate heat. At this time, the heat dissipation plate is needed to control the heat of the shock-absorbing oil, and through the heat transfer of the layer sieve plates, the cooling effect is achieved.

[0013] A heat-sensitive sensor is arranged on the heat dissipation plate. A heat dissipation pipe is arranged on the support housing. A plurality of heat dissipation grooves are opened in the layer sieve plate. The heat dissipation pipe is communicated with the heat dissipation grooves on the layer sieve plate. A heat exchange pump is arranged on the heat dissipation pipe. The heat exchange pump is electrically connected to the heat-sensitive sensor through a wire. The heat-sensitive sensor is electrically connected to the compensation pump through a wire. Through the heat-sensitive sensor, the temperature of the support housing and the shock-absorbing oil is detected. When a certain temperature is reached, the heat exchange pump is started at this time. The heat exchange pump will fill the heat dissipation grooves with a coolant, and the temperature of the coolant will be transferred to the heat dissipation plate, thereby cooling the shock-absorbing oil sufficiently and avoiding the detection error problem caused by overheating.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This device adopts a structure that can automatically disperse and reduce the interference of fluid viscosity. Through the rotation of the group railings and the disturbance of the spoiler rods, the uneven distribution and blockage problems that occur during the fluid flow can be fully reduced.

After the fluid enters the shunt pipe, the phenomenon of liquid backflow or vortex generation during vibration is avoided, the measurement accuracy of the device is improved, and a bilateral detection method is used to correct the measured value. The internal feedback rod can also timely sense the state of the shock-absorbing oil, so that the shock-absorbing oil in the support housing always maintains the best working state, and an automatic induction structure component is used to sense the temperature inside the support housing and perform automatic cooling, reducing the impact on the measurement accuracy.
