[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8In an embodiment of the present invention, a storage tank safety breathing valve with a monitoring function includes a storage tank 1. The upper end of the storage tank 1 is provided with a pressure relief mechanism 2 for relieving pressure and detecting the pressure in the storage tank 1. When the pressure in the storage tank 1 begins to change, the pressure in the storage tank 1 is maintained within a suitable range through the pressure relief mechanism 2. The pressure relief mechanism 2 includes a pressure relief pipe 201. The upper end of the pressure relief pipe 201 is threadedly installed with a sealing cover 202, and the sealing cover 202 is fixedly installed with a protective ring near the lower end of the pressure relief pipe 201. The protective ring makes it easier to install and remove the sealing cover 202. Convenient, a sealing plug 203 is provided in the sealing cover 202, which moves up and down following the pressure change in the storage tank 1. A control mechanism 3 for processing the inlet and outlet gases is provided at the upper end of the storage tank 1 near the pressure relief pipe 201. When the pressure in the storage tank 1 starts to change due to the control mechanism 3, the outlet and intake of the storage tank 1 are controlled by the sealing plug 203 in the pressure relief mechanism. A detection alarm mechanism 4 is provided at the side end of the control mechanism 3. When the pressure in the storage tank 1 exceeds the safe range, the detection alarm mechanism 4 starts to sound an alarm, so that the staff can find it in time.

[0034] See also Figures 1 to 5The upper end of the storage tank 1 is fixedly installed with an installation box 204, and the upper end of the installation box 204 is fixedly installed with a deoxygenation bottle 205, and a deoxygenation liquid is arranged in the deoxygenation bottle 205. When the oxygen in the air reacts with the deoxygenation liquid, the deoxygenation liquid reacts with the oxygen, thereby removing the oxygen in the air and playing a deoxygenation role. The upper end of the deoxygenation bottle 205 is fixedly installed with an intake pipe 206, and the end of the intake pipe 206 away from the deoxygenation bottle 205 is fixedly installed with a leak-proof valve, and the leak-proof valve is set as a one-way valve to prevent the deoxygenation liquid in the deoxygenation bottle 205 from being discharged through the intake pipe 206, which plays a certain protective role, and the lower end of the intake pipe 206 is fixed The deoxygenation bottle 205 is fixedly installed at the lower end of the inner wall of the deoxygenation bottle 205, and the lower end of the air intake pipe 206 is provided with a plurality of air outlets. The air outlets provided at the lower end of the air intake pipe 206 allow the air to enter the deoxygenation liquid stored in the deoxygenation bottle 205 from the lower end of the air intake pipe 206 after the air is inhaled, so that the deoxygenation liquid can completely react with the oxygen in the air, making the deoxygenation efficiency higher. The deoxygenation bottle 205 is fixedly installed with a connecting pipe 207 near the upper end of the air intake pipe 206, and the inner wall of the connecting pipe 207 is provided with a buoyancy ball 208 to prevent the liquid from passing through the connecting pipe 207. The connecting pipe 207 is fixedly installed on the inner wall near the buoyancy ball 208. There is a placement rack 209, and the distance between the placement rack 209 and the buoyancy ball 208 is twice the diameter of the buoyancy ball 208, so as to prevent the air pressure of the suction pipe 206 from driving the buoyancy ball 208 to move upward during the suction process. A retaining ring 210 is fixedly installed on the inner wall of the connecting pipe 207 away from the placement rack 209. When the liquid enters the connecting pipe 207, the liquid causes the buoyancy ball 208 to start moving upward under the action of buoyancy. After the buoyancy ball 208 contacts the retaining ring 210, the connecting pipe 207 is sealed. A drying pipe 211 is fixedly installed on the upper end of the connecting pipe 207, and the drying pipe 211 has a plurality of holes. A desiccant is provided, and a ventilation pipe 212 is fixedly installed on the upper end of the drying pipe 211. The drying pipe 211 arranged on the upper end of the connecting pipe 207 allows the gas to pass through the deoxygenation liquid for deoxygenation. After the gas enters the drying pipe 211, the desiccant arranged in the drying pipe 211 absorbs the water vapor naturally evaporated in the air, so that when the deoxygenated air is transferred to the ventilation pipe 212, the gas in the ventilation pipe 212 remains dry. A ventilation block 213 is fixedly installed on one end of the ventilation pipe 212 away from the drying pipe 211, and ventilation holes are arranged in the ventilation pipe 212, so that the gas in the ventilation block 213 can be transferred through the ventilation block 213 to change the transfer direction more conveniently.

[0035] See also Figures 1 to 5The lower end of the ventilation block 213 is fixedly installed with an outlet pipe 214, and the end of the outlet pipe 214 away from the ventilation block 213 is fixedly installed with a gas reaction box 215, and the end of the gas reaction box 215 away from the outlet pipe 214 is provided with an exhaust pipe 216. A plurality of reaction nets 217 for filtering chemical gases in the exhaust gas are placed in the gas reaction box 215. When the air pressure in the storage pipe enters the ventilation block 213, the air pressure is transmitted to the gas reaction box 215 through the outlet pipe 214, so that the gas discharged from the storage tank 1 reacts with the reaction net 217 provided in the reaction box 215, thereby filtering the harmful substances in the exhaust gas, and making the exhaust pipe The gas discharged from 216 is non-toxic and harmless, and the reaction net 217 is set to a chemical sponge net corresponding to the chemicals stored in the storage tank 1. When the chemical substances in the storage tank 1 are changed, the corresponding reaction net 217 can be replaced, so that the storage tank 1 can replace the chemical substances stored inside more conveniently. A reaction cover 218 is rotatably installed on the upper end of the gas reaction box 215, and a sealing strip is provided on the reaction cover 218 near the edge of the reaction box. The sealing strip installed on the reaction cover 218 allows the gap between the reaction cover 218 and the reaction box to be filled with the sealing strip when the reaction cover 218 is closed, thereby sealing the gas reaction box 215 and the reaction cover 218.

[0036] See also Figures 1 to 5 A filter cartridge 219 is fixedly installed on the side end of the ventilation block 213 away from the ventilation pipe 212, and a waste liquid collecting pipe is arranged at the lower end of the filter cartridge 219. The waste liquid collecting pipe arranged at the lower end of the filter cartridge 219 filters the naturally evaporated chemical liquid carried in the gas discharged from the filter cartridge 219. After the filtered chemical liquid is collected, it flows into the waste liquid collecting pipe, thereby avoiding clogging of the filter cartridge 219. An air transfer pipe 220 is fixedly installed on the upper end of the filter cartridge 219, and the air transfer pipe 220 is arranged as a foldable and bendable hose, and the end of the air transfer pipe 220 away from the drying filter tank is fixedly installed on the upper end of the sealing cover 202, and the air transfer pipe 220 is arranged between the sealing cover 202 and the filter cartridge 219, so that it is more convenient to rotate and disassemble the sealing cover 202, and it is more convenient to clean the inner wall of the sealing cover 202 and the sealing plug 203.

[0037] See also Figures 1 to 6, a mounting frame 221 is fixedly installed on the inner wall of the sealing cover 202, a mounting cylinder 222 is fixedly installed on the lower end of the mounting frame 221, a mounting rod 223 is slidably installed on the lower end of the mounting cylinder 222, and a mounting spring 224 is fixedly installed between the mounting rod 223 and the mounting cylinder 222, and the sealing plug 203 is fixedly installed on the lower end of the mounting rod 223, so that when the sealing plug 203 moves up and down, it drives the mounting rod 223 to move up and down, so that the mounting rod 223 and the mounting cylinder 222 squeeze or stretch the mounting spring 224, so that when the air pressure no longer pushes the sealing plug 203, the mounting spring 224 pushes the mounting rod 223 to restore the original state, so that the movement and sealing of the sealing plug 203 is more convenient, and a sealing ring 225 is fixedly installed on the inner wall of the sealing cover 202 close to the sealing plug 203, and the upper and lower ends of the sealing ring 225 are both inclined, so that when the sealing plug 203 moves up and down, the sealing plug 203 can pass through the sealing ring 225 and contact and slide with the sealing ring 225,

[0038] See also Figures 1 to 7 The control mechanism 3 includes a pull rope 301, and one end of the pull rope 301 is fixedly installed on the upper end of the mounting rod 223, and the pull rope 301 passes through the mounting frame 221 and the sealing cover 202, and the end of the pull rope 301 away from the mounting rod 223 is fixedly installed with a moving rod 302, so that the mounting rod 223 drives the pull rope 301 to move, and the pull rope 301 pulls the moving rod 302 to move more conveniently, and the moving rod 302 is slidably installed on the inner wall of the mounting box 204, and the side end of the moving rod 302 is fixedly installed with a brush block 30 3. The side end of the brush block 303 is slidably connected with a resistance rod 304. When the pull rope 301 pulls the moving rod 302 to start moving, the moving rod 302 drives the brush block 303 to start moving, thereby changing the contact position between the brush block 303 and the resistance rod 304, and changing the resistance of the resistance rod 304. A spring telescopic rod 305 is fixedly installed between the lower end of the moving rod 302 and the installation box 204. When the resistance changes, the distance moved by the brush block 303 is calculated by changing the resistance of the resistance rod 304. The calculation formula is:

[0039] R=ρL / S; ρ represents the resistivity of the material, L represents the length of the conductor, and S represents the cross-sectional area of ​​the conductor.

[0040] Then, the magnitude of the spring force received by the installation spring 224 and the spring telescopic rod 305 on the installation rod 223 is calculated by the moving distance, and the calculation formula is:

[0041] 2x(F=-kx); k represents the spring constant, and x represents the deformation of the spring.

[0042] See also Figures 1 to 8The side end of the moving rod 302 close to the ventilation block 213 is rotatably installed with a connecting telescopic rod 306. When the connecting telescopic rod 306 enables the moving rod 302 to move up and down, the moving rod 302 can also enable the connecting telescopic rod 306 to rotate, and the connecting telescopic rod 306 contracts during the rotation process. The end of the connecting telescopic rod 306 away from the moving rod 302 is fixedly installed with a control rod 307, and the control rod 307 is rotatably installed at the side end of the ventilation block 213, and the other end of the control rod 307 is arranged inside the ventilation block 213, and the end of the control rod 307 away from the connecting telescopic rod 306 is fixedly installed A driving gear 308 is provided, and the driving gear 308 is meshedly connected with a driven gear 309. A control cylinder 310 is fixedly installed on the side end of the driven gear 309, and the control cylinder 310 is rotatably installed on the inner wall of the control block, and a control hole is provided on the control cylinder 310. When the moving rod 302 moves, the moving rod 302 causes the connecting rod to drive the control rod 307 to start rotating, so that the driving gear 308 drives the driven gear 309 to start rotating, so that the control cylinder 310 starts rotating, and the control hole provided on the control cylinder 310 moves to the position of the vent hole provided on the control block, thereby making ventilation more convenient.

[0043] See also Figures 1 to 7The detection alarm mechanism 4 includes a touch switch 401, and the touch switch 401 is provided with two fixedly installed on the inner wall of the installation box 204 close to the moving rod 302, the output end of the touch switch 401 is fixedly installed with a data line 402, the end of the data line 402 away from the touch switch 401 is fixedly installed with a processor 403, and the resistance rod 304 is fixedly installed on the upper end of the processor 403, the above-mentioned processor 403 is a prior art, and no further details are given here.

A test line 406 is fixedly installed on the side end of the processor 403, and an air detector 407 is fixedly installed on the end of the test line 406 away from the processor 403. The above-mentioned air detector 407 is a prior art and will not be described in detail here. The air detector 407 is fixedly installed on the inner wall of the exhaust pipe 216. When the gas discharged from the exhaust pipe 216 contains chemical gases exceeding the normal discharge value, the air detector 407 transmits the detection data to the processor 403 through the test line 406, so that the processor 403 starts the alarm 405 to start working, thereby making it more convenient for the staff to handle.

[0044] The working principle of the present invention is as follows: when the pressure in the storage tank 1 begins to increase, the air pressure in the storage tank 1 pushes the sealing plug 203 to move upward, and the air pressure enters the air transmission tube 220 through the sealing cover 202, and then enters the ventilation block 213 through the filter cartridge 219, pushing the installation rod 223 to move upward, and the spring telescopic rod 305 pulls the moving rod 302 to start moving downward. When the moving rod 302 moves downward, the connecting telescopic rod 306 drives the connecting telescopic rod 306 to start rotating, so that the control rod 307 drives the driving gear 308 to rotate clockwise, and the driving gear 308 drives the driven gear 309 to rotate counterclockwise, driving The control cylinder 310 rotates counterclockwise, so that the control hole set in the control cylinder 310 rotates to the side of the lower vent hole set in the ventilation block 213, so that the air pressure passes through the control cylinder 310 and the ventilation block 213 into the outlet pipe 214, and the air pressure enters the gas reaction box 215 through the outlet pipe 214. The ejected gas passes through the reaction net 217 to react and remove harmful gases in the gas, so that the gas discharged from the exhaust pipe 216 is non-toxic and harmless gas, thereby preventing the chemical gas in the storage tank 1 storing chemical substances from being ejected when the breathing valve ejects gas, and the ejected gas is toxic and harmful gas and absorbed by the staff, causing poisoning.

[0045] When the pressure in the storage tank 1 decreases, the air pressure causes the sealing plug 203 to move downward, causing the installation rod 223 to pull the pull rope 301 downward, causing the pull rope 301 to pull the moving block upward, causing the connecting telescopic rod 306 to start rotating, causing the control rod 307 to drive the driving gear 308 to rotate counterclockwise, and the driving gear 308 drives the driven gear 309 to rotate counterclockwise, driving the control cylinder 310 to rotate counterclockwise, causing the control hole set in the control cylinder 310 to rotate to the side of the upper vent hole set in the vent block 213, so that the suction The air pipe 206 starts to inhale, and the air enters the deoxygenation bottle 205 through the inhalation pipe 206 to remove the oxygen in the air, so that the gas entering the storage tank 1 does not carry oxygen, thereby preventing the oxygen from entering the storage tank 1 and reacting with the chemical substances in the storage tank 1, so that when the storage tank 1 stores chemical substances, the safe exhalation valve in the process of inhalation and exhalation does not carry any harmful chemical gases in the discharged gas, and the gas entering the storage tank 1 does not carry any oxygen, so that the transportation of chemical substances stored in the storage tank 1 is safer and more stable.
