Description

Technical Field

[0001] The utility model belongs to the technical field related to differential pressure transmitters, and particularly relates to a novel intelligent differential pressure transmitter. Background Art

[0002] The working principle of the differential pressure transmitter is based on the principle of torque balance. It converts the measured differential pressure into a corresponding input force through the measuring part. The force acts on the lever system together with the electromagnetic feedback force, causing the lever to produce a small offset, and then converted into a DC 0-10mA current output through the displacement detection amplifier. The application of differential pressure transmitters is very extensive. For example, in liquid level measurement, the liquid level can be measured by the differential pressure transmitter using the differential pressure method. The principle is that the pressure at different heights inside the liquid is different. The pressure per unit area is equal to the liquid level multiplied by the specific gravity of the liquid. By measuring the pressure at a certain height inside the liquid, the height from this point to the liquid surface can be obtained. However, it still has the following disadvantages in actual use:

[0003] 1. During the operation of the differential pressure transmitter, it is usually installed through a mounting base. During the installation process, the installation position needs to be relatively fixed. When facing installation cooperation with different angles, positions, and observation requirements, the applicability is not good enough;

[0004] 2. During the operation of the differential pressure transmitter, the measured fluid is directly transported into it through the positive pressure input terminal and the negative pressure input terminal for measurement. When measuring fluids of different temperatures, the temperature of the fluid may cause errors in the measurement, and the measurement accuracy is not high enough. Utility Model Content

[0005] The purpose of the utility model is to provide a novel intelligent differential pressure transmitter, which solves the problem that the differential pressure transmitter is not suitable for different installation positions during operation and the measurement is greatly affected by temperature by setting a transmitter body, a rotating plate, a mounting plate and a heat dissipation component.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a novel intelligent differential pressure transmitter, comprising a transmitter body, a rotating plate, a mounting plate and a heat dissipation component. Two fixing columns are fixed on both sides of the transmitter body along the center line in the vertical direction. The peripheral side of the fixing column is sleeved with a connecting sleeve. The end of the connecting sleeve away from the transmitter body is fixed with a rotating plate. The rear part between the two rotating plates of the same height is commonly provided with a mounting plate. The bottom of the transmitter body is fixedly connected with a positive pressure input pipe and a negative pressure input pipe along the center line parallel to the long side. The upper part of the peripheral side of the positive pressure input pipe and the negative pressure input pipe is provided with a heat dissipation component. The peripheral side of the positive pressure input pipe and the negative pressure input pipe below the heat dissipation component is fixed with a heating sleeve. When working, the differential pressure of the fluid transported in the positive pressure input pipe and the negative pressure input pipe is measured through the transmitter body, the transmitter body is connected to the mounting plate through the rotating plate, and the mounting plate cooperates with the rotating plate so that the transmitter body can cooperate with the installation of different mounting structures. The heat dissipation component is used to dissipate heat and cool the fluid passing through the positive pressure input pipe and the negative pressure input pipe when overheated.

[0008] Furthermore, a signal bus is fixed at the top center of the transmitter body, and the bottom ends of the positive pressure input pipe and the negative pressure input pipe are fixedly connected with connectors. When the transmitter body is working, signals and electric energy are transmitted through the signal bus, and are connected to the connectors on two pipelines with different pressures through the connectors on the positive pressure input pipe and the negative pressure input pipe.

[0009] Furthermore, a limiting bolt is threadedly connected through the middle of the peripheral side of the connecting sleeve, and the limiting bolt abuts against the peripheral side of the fixing column. When the connecting sleeve is working, the position of the fixing column and the connecting sleeve is limited by the limiting bolt.

[0010] Furthermore, a rotating rod is fixed at the center of both ends of the mounting plate, and the ends of the two rotating rods on the same mounting plate away from the mounting plate are respectively rotatably connected to two rotating plates at the same height. The mounting plate is arranged behind the transmitter body, and the mounting plate has two mounting holes along the center line parallel to the long side on the front side. When the mounting plate is working, it is rotatably connected to the rotating plate through the rotating rod, and is installed together with the external mounting structure through the mounting holes thereon.

[0011] Furthermore, the heat dissipation component includes heat sinks, and the upper parts of the circumferences of the positive pressure input tube and the negative pressure input tube are fixed with heat sinks parallel to each other at equal intervals, and the heat dissipation component is fixed to the corresponding positive pressure input tube or negative pressure input tube through the heat sinks.

[0012] Furthermore, the heat dissipation assembly also includes an air inlet frame and a fan. The fan is fixed in the air inlet frame, and all the heat sinks are fixed on one side of the air inlet frame. When the fan is working, air is drawn into the air inlet frame, so that the airflow passes through the heat sink to dissipate heat.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that the differential pressure transmitter is not suitable for different installation positions during operation by arranging a transmitter body, a rotating plate and a mounting plate. The installation method required for the transmitter body and the position of the mounting structure are determined, and the rotating plate can be rotated immediately. After the four rotating plates are rotated at appropriate angles, the limit bolts on each connecting sleeve can be rotated until the limit bolts are pressed tightly against the fixing column to limit the position between the fixing column and the connecting sleeve. The mounting plate is then rotated to align with the installation position, the mounting bolts are inserted into the mounting holes, and then screwed into the installation position. The transmitter body can be installed in a suitable position, making the differential pressure transmitter more suitable for installation.

[0015] 2. The utility model solves the problem that the measurement of the differential pressure transmitter is greatly affected by temperature by setting a transmitter body and a heat dissipation component. When the temperature of the transported fluid is high, the operator starts the fan, and the fan draws air from the external connection into the air inlet frame, and transports it to between the heat sinks through the air inlet frame. The heat sinks cool the fluid transported in the positive pressure input pipe and the negative pressure input pipe. When the temperature of the transported fluid is too low, the operator starts the heating jacket to heat the fluid transported in the positive pressure input pipe and the negative pressure input pipe, so that the fluid transported in the positive pressure input pipe and the negative pressure input pipe is always maintained at a suitable temperature, and the differential pressure transmitter measurement is less affected by temperature.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0026] See also Figure 1-4 The utility model is a novel intelligent differential pressure transmitter, comprising a transmitter body 1, a rotating plate 2, a mounting plate 3 and a heat dissipation component 4. Two fixing columns 101 are fixed on both sides of the transmitter body 1 along the center line in the vertical direction. When the transmitter body 1 is working, the differential pressure of the fluid input in the positive pressure input pipe 103 and the negative pressure input pipe 102 is measured. The connecting sleeve 201 is connected through the fixing column 101. The peripheral side of the fixing column 101 is sleeved with the connecting sleeve 201. When working through the connecting sleeve 201, the rotating plate 2 is connected to the fixed column 101. The rotating plate 2 is fixed at one end of the connecting sleeve 201 away from the transmitter body 1. The mounting plate 3 is arranged behind the transmitter body 1 through the rotating plate 2. The rear part between the two rotating plates 2 of the same height is jointly provided with the mounting plate 3. The transmitter body 1 is installed through the mounting plate 3. 1 is fixedly connected with a positive pressure input pipe 103 and a negative pressure input pipe 102 along a center line parallel to the long side. The positive pressure input pipe 103 and the negative pressure input pipe 102 respectively input the fluid with differential pressure into the transmitter body 1, and the fluid with high pressure is transported through the positive pressure input pipe 103, and the fluid with low pressure is transported through the negative pressure input pipe 102. The upper parts of the peripheral sides of the positive pressure input pipe 103 and the negative pressure input pipe 102 are both provided with a heat dissipation component 4. The heat dissipation component 4 cooperates to dissipate the heat of the fluid entering the transmitter body 1. A heating sleeve 105 is fixedly provided on the peripheral sides of the positive pressure input pipe 103 and the negative pressure input pipe 102 below the heat dissipation component 4. The heating sleeve 105 heats the fluid passing through the positive pressure input pipe 103 and the negative pressure input pipe 102, so that the fluid passing through the positive pressure input pipe 103 and the negative pressure input pipe 102 is heated to prevent the fluid temperature from being too low.

[0027] Specifically, a signal bus 106 is fixed at the top center of the transmitter body 1, and the bottom ends of the positive pressure input pipe 103 and the negative pressure input pipe 102 are fixedly connected with a connector 104. When the transmitter body 1 is working, the data measured in the transmitter body 1 is output through the signal bus 106, and the positive pressure input pipe 103 and the negative pressure input pipe 102 are respectively connected to the output end of the fluid with a higher or lower pressure through the connector 104, and the fluid is transported to the positive pressure input pipe 103 or the negative pressure input pipe 102.

[0028] Furthermore, a limiting bolt 202 is threadedly connected to the middle of the peripheral side of the connecting sleeve 201 , and the limiting bolt 202 abuts against the peripheral side of the fixing column 101 . The position of the connecting sleeve 201 and the fixing column 101 is limited by the limiting bolt 202 .

[0029] Furthermore, a rotating rod 302 is fixed at the center of both ends of the mounting plate 3. The two rotating rods 302 on the same mounting plate 3 are rotatably connected to the two rotating plates 2 at the same height at one end away from the mounting plate 3. The mounting plate 3 is arranged at the rear of the transmitter body 1. The mounting plate 3 has two mounting holes 301 along the center line parallel to the long side on the front side. The mounting plate 3 is rotatably connected to the rotating plate 2 through the rotating rod 302, and is connected to the mounting bolts through the mounting holes 301 thereon.

[0030] The operation process of this embodiment is as follows: when working, first determine the installation method required for the transmitter body 1 and the position of the installation structure, then rotate the rotating plate 2, so that the four rotating plates 2 are rotated at a suitable angle, then rotate the limiting bolt 202 on each connecting sleeve 201 until the limiting bolt 202 is pressed against the fixing column 101, and the position between the fixing column 101 and the connecting sleeve 201 is limited, then rotate the mounting plate 3, rotate the mounting plate 3 to align with the installation position, insert the mounting bolt into the mounting hole 301, and then screw it into the installation position, and then install the transmitter body 1 in the appropriate position. Specific embodiment 2

[0032] See also Figure 1 , 2 5. Based on the specific embodiment 1, the heat dissipation component 4 includes a heat sink 403, and the upper parts of the positive pressure input tube 103 and the negative pressure input tube 102 are fixed with heat sinks 403 parallel to each other at equal intervals, and heat is dissipated by the heat sink 403 in cooperation with the fan 402.

[0033] Specifically, the heat dissipation component 4 also includes an air inlet frame 401 and a fan 402. The fan 402 is fixed in the air inlet frame 401, and all heat sinks 403 are fixed on one side of the air inlet frame 401. The outside air is drawn into the air inlet frame 401 through the fan 402 and then blown between the heat sinks 403 for heat dissipation.

[0034] The operation process of this embodiment is: when measuring, the joint on the pipeline with a larger delivery pressure is connected to the connector 104 at the bottom of the positive pressure input pipe 103, and the joint on the pipeline with a smaller delivery pressure is connected to the connector 104 at the bottom of the negative pressure input pipe 102, so that the differential pressure between the measured fluids can be measured through the transmitter body 1. When the temperature of the delivered fluid is high, the operator starts the fan 402, and the fan 402 draws air from the external connection into the air inlet frame 401, and delivers it to between the heat sinks 403 through the air inlet frame 401, and cools the fluids delivered in the positive pressure input pipe 103 and the negative pressure input pipe 102 through the heat sink 403. When the temperature of the delivered fluid is too low, the operator starts the heating sleeve 105 to heat the fluids delivered in the positive pressure input pipe 103 and the negative pressure input pipe 102, so that the fluids delivered in the positive pressure input pipe 103 and the negative pressure input pipe 102 are always maintained at a suitable temperature.
