Description

Technical Field

[0001] The utility model relates to the technical field of a heat dissipation damper and application thereof in a differential pressure transmitter, in particular to a shock absorbing device for a differential pressure transmitter. Background Art

[0002] The differential pressure transmitter can measure the pressure difference between the two ends of the transmitter. Affected by factors such as the on-site installation environment and process conditions, some differential pressure transmitters are installed in places with large vibrations on site. Large vibrations will cause the measurement data of the differential pressure transmitter to be unstable and fluctuate greatly, affecting the accuracy of the flow meter's measurement data and the normal operation of the differential pressure transmitter. In order to solve the above problems, a damper is usually installed at the bottom of the differential pressure transmitter to reduce the impact of vibration on the differential pressure transmitter. However, after the damper has been working for a long time, the temperature of the damper will increase due to the work done by the air in the cylinder and the increase in friction between the cylinder wall and the piston rod, affecting its service life. In order to solve the above-mentioned damper heating problem, Chinese patent CN221880088U discloses a viscous damper with a heat dissipation function, including a damper housing, a piston rod, a sealing ring and a piston head with a hole. A heat dissipation component is provided on the outer periphery of the damper housing, and fixed components are provided on both sides of the heat dissipation component. The heat dissipation component includes a heat dissipation pipe surrounding the damper housing, a fixed plate provided on one side of the heat dissipation pipe, a water tank fixed on one side of the fixed plate, a heat sink provided on one side of the water tank, and a heat dissipation fan provided on one side of the heat sink. The above-mentioned heat dissipation and cooling is achieved by winding a heat dissipation pipe connected to a water tank around the outer circumference of the damper shell. The above-mentioned damper needs to be installed with a water tank that can provide water and a heat sink and a heat dissipation fan for reducing the water temperature in the water tank to achieve heat dissipation of the damper. However, the water tank, heat sink and heat dissipation fan have a complex structure and are inconvenient to install on the damper. Utility Model Content

[0020] The technical solution of the present invention will be further elaborated in detail below in conjunction with specific embodiments. Parts that are not described in detail in the following embodiments of the present invention, such as the vibration detector detecting the vibration signal, the flat iron extending into the ground to guide the earthquake source into the ground, etc., should be immediately known to those skilled in the art or should be known to the prior art.

[0021] A shock absorbing device for a differential pressure transmitter, such as Figure 1-4 As shown, the device comprises a flat plate 2, with a vertical mounting rod 3 welded to the middle of the upper side of the plate 2. This vertical mounting rod 3 is a steel pipe, and the differential pressure transmitter can be mounted on this vertical mounting rod 3. Three support rods 4 are evenly spaced at the bottom of the plate 2 to support the plate 2. The upper ends of the three support rods 4 are connected to the plate 2. Each support rod 4 is composed of three sections, distributed from top to bottom: support rod 1 401, support rod 2 402, and support rod 3 403.

[0022] Two heat dissipation dampers 1 are mounted on each support rod 4. One heat dissipation damper 1 is mounted between support rod 1 401 and support rod 2 402 in the middle of the corresponding support rod 4. The upper end of support rod 1 401 is connected to the flat plate 2, and its lower end is connected to the top of the piston rod 102 of the corresponding heat dissipation damper 1. The upper end of support rod 2 402 is fixedly connected to the bottom of the cylinder 101 of the corresponding heat dissipation damper 1. The other heat dissipation damper 1 is mounted between support rod 2 402 and support rod 3 403 in the lower middle portion of the corresponding support rod 4. The lower end of support rod 2 402 is connected to the top of the piston rod 102 of the corresponding heat dissipation damper 1, and the upper end of support rod 3 403 is fixed to the bottom of the cylinder 101 of the corresponding heat dissipation damper 1.

[0023] The heat dissipation damper 1 comprises a cylinder 101 and a piston rod 102 mounted therein, with a sealing retainer installed between the cylinder 101 and the piston rod 102. A cooling water channel 103 is spirally wound from top to bottom within the cylinder wall of the cylinder 101, for admitting cooling water. An opening in the upper left wall of the cylinder 101 serves as an inlet 1031 for cooling water to enter the cooling water channel 103, while an opening in the lower right wall of the cylinder 101 serves as an outlet 1032 for cooling water to exit the cooling water channel 103.

[0024] The water inlet 1031 and water outlet 1032 are connected by a circulating water pipe 104. The left end of the circulating water pipe 104 is connected to the water inlet 1031, and the right end of the circulating water pipe 104 is connected to the water outlet 1032. The circulating water pipe 104 is connected to a water pump 105. The circulating water pipe 104 is a flat tube that increases the heat dissipation area of the cooling water. To facilitate docking and installation of the circulating water pipe 104, the shapes of the water inlet 1031 and water outlet 1032 are consistent with the shape of the circulating water pipe 104.

[0025] In addition, multiple turns are arranged in the middle of the circulating water pipe 104 to increase the time the cooling water stays in the circulating water pipe 104, so that the cooling water can dissipate the heat absorbed in the cylinder 101 when flowing in the circulating water pipe 104, thereby lowering the temperature of the cooling water and facilitating its circulation into the cooling water channel 103 to lower the temperature in the damper cylinder 101.

[0026] Furthermore, the flat plate 2 is divided into three equal parts at 120°, and each of the three equal parts is provided with a strip-shaped hole 201 extending along the line of the trisection. Each strip-shaped hole 201 is fitted with an adjusting bolt 202, which is fitted with a flat washer. The support rods 4 are provided with threaded holes at the top. The adjusting bolts 202 pass through the corresponding strip-shaped hole 201 and then into the corresponding threaded hole at the top of the support rod 4 to adjust and secure the position of the support rod 4.

[0027] The lower ends of the three support rods 4 are connected by a connecting ring 6, which includes three connecting arc plates. The three connecting arc plates respectively fix the bottoms of the three support rods 4, and multiple connecting holes are respectively opened on the opposite ends of two adjacent connecting arc plates. The multiple connecting holes are evenly spaced along the length direction of the connecting arc plates.

[0028] After the positions of the upper ends of the three support rods 4 are adjusted, and the positions of the lower ends of the three support rods 4 are adjusted accordingly, the corresponding two connecting holes on the two adjacent connecting arc plates are aligned, and the connecting bolts are inserted into the two aligned connecting holes to fix the two adjacent connecting arc plates together, thereby achieving a fixed connection of the lower ends of the three support rods 4, and then the shock absorber is adjusted in time according to the on-site installation conditions.

[0029] In addition, a flat iron 7 is led out from the connecting ring 6. One end of the flat iron 7 is fixedly connected to the connecting ring 6, and the other end extends to the ground, so as to guide the earthquake source into the ground, reduce the vibration of the differential pressure transmitter, and improve the accuracy of the output data of the differential pressure transmitter.
