Description

Technical Field

[0001] The utility model relates to the field of pressure gauges, in particular to a shock-resistant mechanical pressure gauge. Background Art

[0002] Pressure gauge (English name: pressure gauge) refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the ambient pressure. It is widely used and is almost everywhere in all industrial processes and scientific research fields. It can be seen everywhere in the fields of thermal pipelines, oil and gas transmission, water and gas supply systems, vehicle repair and maintenance shops, etc. Especially in the process of industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used because of the high mechanical strength and convenient production of the elastic sensitive elements of mechanical pressure gauges. The working principle of the mechanical pressure gauge is to use the elastic deformation of the sensitive elements (Bourdon tube, diaphragm box, bellows) in the gauge, and then the conversion mechanism of the movement in the gauge transmits the pressure deformation to the pointer, causing the pointer to rotate to display the pressure.

[0003] However, during use, the existing mechanical pressure gauge is generally installed at any position of the equipment or pipeline that needs to measure pressure. However, in order to reduce errors, it is best to choose a middle position and avoid installing it at a bend or joint. Due to the different pressures inside the pipeline and the vibrations caused by the external working environment, the pressure gauge often shakes during detection, affecting the detection accuracy of the pressure gauge, while reducing the service life of the equipment, making it inconvenient for long-term use. In addition, when the existing pressure gauge detects excessively high pipeline pressure, the pressure gauge cannot give prompts and warnings, resulting in the staff being unable to deal with the internal situation of the pressure gauge in a timely manner, which may cause accidents such as explosions. There are certain installation risks and it is inconvenient for the staff to use. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing mechanical pressure gauge is generally installed at any position of the equipment or pipeline that needs to measure the pressure during use. However, in order to reduce the error, it is best to choose the middle position and avoid installing it at the bend or joint. Due to the different pressures inside the pipeline and the vibrations generated by the external working environment, the pressure gauge often shakes continuously during detection, affecting the detection accuracy of the pressure gauge, while reducing the service life of the equipment, making it inconvenient for long-term use. In addition, when the existing pressure gauge detects excessively high pressure in the pipeline, the pressure gauge cannot give prompts and warnings, resulting in the staff being unable to deal with the internal situation of the pressure gauge in time, which may cause accidents such as explosions, and there are certain installation hazards, which are inconvenient for the staff to use.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a seismic-resistant mechanical pressure gauge, including a buffer plate, and also including:

[0006] Two limit grooves are both arranged at the center of the inner walls on the left and right sides of the buffer plate, the two limit grooves are respectively slidably connected to limit blocks, and the two limit blocks are fixedly connected to a pressure gauge on one side away from the buffer plate;

[0007] The early warning board is fixedly installed at the center of the rear surface of the buffer board. A running green light is arranged on the left side of the rear surface of the early warning board, a prompt yellow light is arranged at the center of the rear surface of the early warning board, and an alarm red light is arranged on the right side of the rear surface of the early warning board.

[0008] Preferably, a mounting seat is fixedly connected to the bottom of the pressure gauge, and a threaded connection port is provided at the bottom of the mounting seat.

[0009] Preferably, an exhaust plug is provided on the top of the pressure gauge, an explosion-proof plug is provided at the center of the rear surface of the pressure gauge, and a pointer speed sensor is provided inside the dial of the pressure gauge. When the pointer rotates, the sensor is activated and fed back to the early warning board, which is displayed by running a green light and a yellow prompt light on the early warning board.

[0010] Preferably, a pressure sensor is fixedly mounted on a side of the inner wall of the buffer plate close to the explosion-proof plug, and a signal output end of the pressure sensor is electrically connected to a signal receiving end of the early warning board.

[0011] Preferably, a buzzer is fixedly mounted on one side of the left outer wall of the buffer plate close to the top, and a signal receiving end of the buzzer is electrically connected to a signal output end of the early warning board.

[0012] Preferably, two telescopic rods are fixedly connected to the inner wall of the buffer plate, and one side of the two telescopic rods away from the buffer plate is fixedly connected to the rear surface of the pressure gauge.

[0013] Preferably, the outer surfaces of the two telescopic rods are sleeved with shock-absorbing springs, and the sides of the two shock-absorbing springs away from the buffer plate are fixedly connected to the rear surface of the pressure gauge, and the sides of the two shock-absorbing springs away from the pressure gauge are fixedly connected to the inner wall of the buffer plate.

[0014] Preferably, the left and right sides of the bottom of the buffer plate are fixedly connected with fixing feet, and the sides of the two fixing feet away from the pressure gauge are provided with mounting bolts.

[0015] Compared with the prior art, the advantages and positive effects of the utility model are:

[0016] 1. When using the utility model, the staff will fix the pressure gauge with the equipment or pipeline that needs to measure pressure through the bottom mounting seat and the threaded connection port, and then fix the buffer plate in the corresponding position through two fixing feet and mounting bolts to enhance the stability of the pressure gauge during operation. When the pressure gauge keeps shaking, the impact force generated by the shaking of the pressure gauge is absorbed by the elastic force of the two telescopic rods and the two shock-absorbing springs to reduce the shaking of the pressure gauge, and the shaking of the pressure gauge is limited by the sliding connection of the two limit grooves and the two limit blocks on both sides, further sharing the impact force of the pressure gauge in the left and right directions, and cooperating with the two shock-absorbing springs to greatly reduce the shaking of the pressure gauge, enhance the stability of the pressure gauge during detection, increase the service life, and facilitate installation and use by the staff.

[0017] 2. During use, the utility model, when the pressure gauge starts to detect the pressure, if the internal pressure of the pressure gauge is normal, the green light on the early warning panel will be on for a long time; if the pointer inside the pressure gauge rotates rapidly, it means that the internal pressure of the pressure gauge is unstable, and the yellow light on the early warning panel will be on for a long time, prompting the staff to discharge the pressure of the pressure gauge. At this time, the staff can exhaust the pressure through the exhaust plug on the top of the pressure gauge, which is convenient for the staff to inspect and repair; if the explosion-proof plug on the rear surface of the pressure gauge is pushed out, it means that the internal pressure of the pressure gauge is too high, and the explosion-proof plug collides with the pressure sensor when being pushed out, causing the red alarm light on the early warning panel to flash for a long time, and the buzzer will continuously sound the alarm, prompting the staff to find the situation and deal with it as soon as possible, so as to prevent safety accidents and facilitate the staff to inspect and use.

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0027] Embodiment 1, as Figure 1-6 As shown, the utility model provides a seismic-resistant mechanical pressure gauge, including a buffer plate 1, and also including:

[0028] Two limit grooves 101 are provided at the center of the inner walls on the left and right sides of the buffer plate 1. The two limit grooves 101 are respectively slidably connected to the limit blocks 201. The two limit blocks 201 are fixedly connected to the pressure gauge 2 on the side away from the buffer plate 1.

[0029] The warning board 8 is fixedly installed at the center of the rear surface of the buffer board 1. A running green light 801 is set on the left side of the rear surface of the warning board 8, a prompt yellow light 802 is set at the center of the rear surface of the warning board 8, and an alarm red light 803 is set on the right side of the rear surface of the warning board 8.

[0030] Further, such as Figure 1-6 As shown, the bottom of the pressure gauge 2 is fixedly connected with a mounting base 3, and a threaded connection port 301 is provided at the bottom of the mounting base 3, which is mainly used to connect with the corresponding pipeline through the threaded connection port 301 at the bottom of the mounting base 3.

[0031] Further, such as Figure 1-6 As shown, a vent plug 4 is provided on the top of the pressure gauge 2, and an explosion-proof plug 5 is provided at the center of the rear surface of the pressure gauge 2. The main function of the vent plug 4 is to discharge the pressure inside the pressure gauge 2, and the explosion-proof plug 5 is mainly to prevent the pressure gauge 2 from exploding due to excessive pressure.

[0032] Further, such as Figure 1-6As shown, a pressure sensor 6 is fixedly installed on one side of the inner wall of the buffer plate 1 close to the explosion-proof plug 5, and the signal output end of the pressure sensor 6 is electrically connected to the signal receiving end of the early warning board 8. The main function is that if the explosion-proof plug 5 on the rear surface of the pressure gauge 2 is pushed out, it means that the internal pressure of the pressure gauge 2 is too high, and the explosion-proof plug 5 collides with the pressure sensor 6 when being pushed out, causing the red alarm light 803 on the early warning board 8 to flash for a long time.

[0033] Further, such as Figure 1-6 As shown, a buzzer 9 is fixedly installed on one side of the left outer wall of the buffer plate 1 near the top, and the signal receiving end of the buzzer 9 is electrically connected to the signal output end of the early warning board 8. Its main function is to turn on the buzzer 9 to continuously alarm and give prompts through the long flashing of the alarm red light 803 on the early warning board 8, so that the staff can discover the situation and deal with it in the first time, prevent safety accidents, and facilitate maintenance and use by the staff.

[0034] Further, such as Figure 1-6 As shown, two telescopic rods 10 are fixedly connected to the inner wall of the buffer plate 1, and the two telescopic rods 10 are fixedly connected to the rear surface of the pressure gauge 2 on the side away from the buffer plate 1. The main function of the two telescopic rods 10 and the elastic force of the two shock-absorbing springs 11 is to absorb the impact force generated by the shaking of the pressure gauge 2 when the pressure gauge 2 is constantly shaking, thereby reducing the shaking of the pressure gauge 2.

[0035] Further, such as Figure 1-6 As shown, the outer surfaces of the two telescopic rods 10 are sleeved with shock-absorbing springs 11, and the two shock-absorbing springs 11 are fixedly connected to the rear surface of the pressure gauge 2 on the side away from the buffer plate 1, and the two shock-absorbing springs 11 are fixedly connected to the inner wall of the buffer plate 1 on the side away from the pressure gauge 2. The main function is to limit the shaking of the pressure gauge 2 through the sliding connection between the two limiting grooves 101 on both sides and the two limiting blocks 201 respectively, to further share the impact force of the pressure gauge 2 in the left and right directions, and to cooperate with the two shock-absorbing springs 11 to greatly reduce the shaking of the pressure gauge 2, enhance the stability of the pressure gauge 2 during detection, enhance the service life, and facilitate installation and use by the staff.

[0036] Further, such as Figure 1-6 As shown, the left and right sides of the bottom of the buffer plate 1 are fixedly connected with fixing feet 7, and the two fixing feet 7 are provided with mounting bolts 701 on the side away from the pressure gauge 2. The main function is to fix the buffer plate 1 through the two fixing feet 7 and the mounting bolts 701 to enhance the stability of the pressure gauge 2 during operation.

[0037] Working principle: When using the utility model, the staff will fix the pressure gauge 2 with the equipment or pipeline where the pressure needs to be measured through the bottom mounting seat 3 and the threaded connection port 301, and then fix the buffer plate 1 in the corresponding position through the two fixing feet 7 and the mounting bolts 701 to enhance the stability of the pressure gauge 2 during operation. When the pressure gauge 2 is constantly shaking, the impact force generated by the shaking of the pressure gauge 2 is absorbed by the elastic force of the two telescopic rods 10 and the two shock-absorbing springs 11 to reduce the shaking of the pressure gauge 2, and the shaking of the pressure gauge 2 is limited by the sliding connection of the two limiting grooves 101 and the two limiting blocks 201 respectively, further sharing the impact force of the pressure gauge 2 in the left and right directions, and cooperating with the two shock-absorbing springs 11 to greatly reduce the shaking of the pressure gauge 2, enhance the stability of the pressure gauge 2 during detection, and enhance the service life, which is convenient for the staff to install and use. When the pressure gauge 2 starts to detect the pressure, if the internal pressure of the pressure gauge 2 is normal, the running green light 801 on the early warning board 8 is long on. If the pointer inside the pressure gauge 2 rotates quickly, it means that the internal pressure of the pressure gauge 2 is unstable. At this time, the yellow light 802 on the early warning board 8 is long on, prompting the staff to discharge the pressure of the pressure gauge 2. At this time, the staff can exhaust the pressure through the exhaust plug 4 on the top of the pressure gauge 2, which is convenient for the staff to carry out maintenance. If the explosion-proof plug 5 on the rear surface of the pressure gauge 2 is pushed out, it means that the internal pressure of the pressure gauge 2 is too large, and the explosion-proof plug 5 collides with the pressure sensor 6 when being pushed out, and the signal is transmitted to the early warning board 8 through the pressure sensor 6, so that the alarm red light 803 on the early warning board 8 flashes for a long time, and the buzzer 9 continuously sends out alarms, prompting the staff to discover the situation and deal with it as soon as possible to prevent safety accidents and facilitate maintenance and use by the staff.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
