Description

Technical Field

[0001] The present invention relates to the technical field of pressure gauges, and specifically to a special anti-seismic pressure gauge for high temperature, high pressure and high sulfur resistance. Background Art

[0002] The pressure gauges in the prior art perform poorly in high temperature, high pressure and high sulfur environments. First of all, most pressure gauges rely on a single measurement mechanism, such as only using force-sensitive resistors or strain sensors. Once the sensor fails, the measurement fails, lacking redundant protection. Secondly, the high temperature environment accelerates the aging of the sensor. Most of the existing heat dissipation measures are passive, which are difficult to effectively protect the sensor, resulting in a decrease in accuracy and a shortening of the service life. Thirdly, dust particles are easy to accumulate inside the device, blocking the heat dissipation channels and requiring frequent manual cleaning, increasing the maintenance burden. Fourthly, the existing design does not effectively isolate the measured environment from the sensor, and the high temperature and high sulfur directly damage the electronic devices, reducing the durability. Finally, the heat dissipation system lacks the ability to adjust and cannot optimize the heat dissipation efficiency according to the temperature change, limiting the application under extreme conditions.

This self-cleaning design reduces the frequency and difficulty of manual cleaning, and is particularly suitable for industrial environments with a lot of dust, greatly reducing maintenance costs; (4) The piston pressure column of the present invention isolates the environment to be tested from the sensor, preventing direct damage to electronic devices in high temperature, high pressure, and high sulfur environments. It not only protects the physical structure of the sensor, but also avoids chemical corrosion, ensuring the long-term stable operation of the pressure gauge under harsh conditions; (5) Since the present invention does not use moving parts to detect pressure, it can effectively reduce the impact of vibration on the overall when dealing with vibration scenarios.

[0027] The four corners of the inner wall of the middle enclosure 111 are fixedly installed with guide plate installation platforms 131, and four movable guide plates 113 are rotatably installed on the four guide plate installation platforms 131. The movable guide plates 113 are arranged at the edge of one side of the external heat sink 109 close to the inner heat sink 105. A driving shaft 116 is arranged in the air above the force-bearing top frame 107. The driving shaft 116 is coaxially arranged with the extrusion middle shaft 106. A guide groove 117 is provided on the driving shaft 116. A driving blade toggle bracket 120 is slidably installed in the guide groove 117. A driving blade support tube 115 is rotatably and slidably sleeved on the outer surface of the driving shaft 116. The bottom end of the driving blade support tube 115 is movably connected to the four movable guide plates 113 through four connecting rods 114. A driving blade 118 is rotatably mounted on the driving blade support tube 115. The driving blade 118 and the driving blade support tube 115 can only rotate circumferentially, and the driving blade 118 and the driving blade support tube 115 cannot move axially. The driving blade moving bracket 120 is fixedly matched with the driving blade 118, so that the rotation of the driving shaft 116 can drive the driving blade 118 to rotate. The bottom end of the driving shaft 116 is provided with a ring for preventing the driving blade support tube 115 from separating from the driving shaft 116.

[0028] The driving shaft 116 is fixedly mounted on the output shaft of the driving motor 125, and the driving motor 125 is fixed in the top enclosure 121 through the driving motor bracket 124. A spring 119 is rotatably mounted between the driving blade toggle bracket 120 and the driving motor bracket 124. The spring 119 is arranged around the outside of the driving shaft 116. The top enclosure 121 is fixedly mounted on the middle enclosure 111. The four corners of the top enclosure 121 are also fixedly mounted with batteries 123 for providing power to the driving motor 125 and the refrigeration secondary sheet 110. (In addition, an external power supply is also provided). The top of the top enclosure 121 is fixedly installed with an air intake isolation enclosure 122 through a top sealing plate 132, and a guide slide bar 126 is fixedly installed in the air intake isolation enclosure 122 at the axial position; an air intake isolation cover 127 is sleeved on the outer side of the air intake isolation enclosure 122, and the air intake isolation cover 127 is overlapped on the top sealing plate 132, wherein the upper surface of the top sealing plate 132 is flush with the bottom edge of the top enclosure 121. A plurality of air intake nozzles 128 are fixedly installed along a tangential circular array on the circumferential surface of the air intake isolation cover 127, and the air intake nozzles 128 are connected to the inside of the air intake isolation cover 127, wherein the axial position of the air intake isolation cover 127 is slidably matched with the guide slide bar 126, and a collar is provided at the top end of the guide slide bar 126 to limit the air intake isolation cover 127 from falling off the guide slide bar 126.

[0029] The working principle of a special seismic pressure gauge for high temperature, high pressure and high sulfur disclosed by the present invention is as follows: According to the usage scenario, a sealing disc 133 is selected for installation. The sealing disc 133 plugs one end of the pressure measuring pipeline 101, and the other end of the pressure measuring pipeline 101 is communicated with the space to be pressure-tested through a flange 129; or both ends of the pressure measuring pipeline 101 are flanges 129, and it is connected in series to the pipeline to be pressure-tested. When there is pressure inside the pressure measuring pipeline 101 (when there is pressure in the space to be measured), the pressure will squeeze the piston pressure column 103, the piston pressure column 103 will squeeze the extrusion central axis 106, the extrusion central axis 106 will squeeze the force-sensitive resistor 108. After being squeezed, the resistance value of the force-sensitive resistor 108 will change, and the resistance value is linearly related to the applied pressure. At the same time, when the extrusion central axis 106 squeezes the force-sensitive resistor 108, it will also squeeze the force-receiving top frame 107, causing the force-receiving top frame 107 to deform. The strain sensor provided on the force-receiving top frame 107 is used to judge the deformation amount of the force-receiving top frame 107, and the deformation amount of the force-receiving top frame 107 is linearly related to its force-receiving relationship. Therefore, the dual redundant measurement of the pressure inside the pressure measuring pipeline 101 is realized through the force-sensitive resistor 108 and the strain sensor on the force-receiving top frame 107.

[0030] When there is a high temperature and high sulfur environment inside the pressure measuring pipeline 101 (the piston pressure column 103 is set to separate the environment to be measured from the external sensor, thereby preventing damage to its electronic devices), the temperature will be transferred to the piston pressure column 103 and the mounting seat 102, wherein the mounting seat 102 and the extrusion center shaft 106 are made of a material with low thermal conductivity, such as titanium alloy. When in use, when the high temperature is too high (the middle enclosure 111 has a built-in temperature sensor), the drive motor 125 is started, the output shaft of the drive motor 125 drives the drive shaft 116 to rotate, the drive shaft 116 drives the guide groove 117 to rotate, the guide groove 117 drives the drive blade toggle bracket 120 to rotate, the drive blade toggle bracket 120 drives the drive blade 118 to rotate, and the drive blade 118 drives the external air to pass through the air inlet nozzle 128 along the inner wall of the air inlet isolation cover 127 tangentially into the air inlet isolation cover 127, and then rotate inside the air inlet isolation cover 127. During the rotation process, the particles in the air will be subjected to the centrifugal force to rotate along the inner wall of the air inlet isolation cover 127, and the air will enter the air inlet isolation enclosure 122 (the particles will rotate under the influence of gravity and centrifugal force). , and then enters the top frame 121, driving the blades 118 to blow air to the inner heat sink 105, thereby cooling the inner heat sink 105. The heat on the extrusion center axis 106 will be transferred to the inner heat sink 105, thereby cooling the extrusion center axis 106. During this process, the airflow will also pass through the inner heat sink 105 into the mounting base 102, and then pass through the exhaust groove 104 and be blown out along the outer surface of the pressure measuring pipe 101. During this process, a low-pressure area will be formed inside the bottom bevel frame 112, resulting in the pressure above the external heat sink 109 being greater than the pressure below. At this time, the air above the external heat sink 109 will flow downward. When the ambient temperature continues to rise, the secondary cooling sheet 110 is started, and the cooling surface of the secondary cooling sheet 110 transfers the low temperature to the inner heat sink 105 through the inner heat sink heat conducting seat 130, and then cools the extrusion center axis 106, the purpose of which is to reduce the influence of the high temperature on the force-bearing top frame 107 and the force-sensitive resistor 108. The heating surface of the secondary cooling sheet 110 transfers the temperature to the external heat sink 109, and the flowing air dissipates the heat from the external heat sink 109.Meanwhile, the rotational speed of the drive motor 125 is controlled to increase according to the situation. The increase in the rotational speed of the drive motor 125 will drive the increase in the rotational speed of the drive blade 118. The rotation of the drive blade 118 generates lift, thereby compressing the spring 119. After the spring 119 is compressed, it will cause the drive blade to move the bracket 120 to slide inside the guiding groove 117. At this time, the drive blade 118 will axially displace along the drive shaft 116. The drive blade 118 drives the drive blade support tube 115 to slide on the drive shaft 116. The drive blade support tube 115 pulls the four movable guide vanes 113 to swing through the four connecting rods 114, causing the movable guide vanes 113 to swing towards the center of the drive blade 118. At this time, the air blown downward by the drive blade 118 will be diverted to the external heat sink 109 through the movable guide vanes 113, thereby accelerating the air flow rate that the external heat sink 109 can pass through, and further increasing the heat dissipation capacity of the external heat sink 109.

[0031] In addition, when self-cleaning is required, the drive motor 125 is started in reverse. The output shaft of the drive motor 125 drives the drive blade 118 to rotate in reverse. The drive blade 118 will drive the air to flow from bottom to top, and then blow the air towards the intake isolation cover 127. At this time, the intake isolation cover 127 is pushed by the upward air and will slide on the guiding slide rod 126. Then the bottom edge of the intake isolation cover 127 will separate from the top sealing plate 132, thus generating a gap, and then blowing out the dust particles deposited between the intake isolation cover 127 and the intake isolation wall 122.
