[0002] A heater is an electrical appliance that uses electrical energy to achieve a heating effect. It is small in size, has high heating power, is widely used, uses an intelligent control mode, has high temperature control accuracy, and can be connected to a computer. It has a wide range of applications, long life, and high reliability. The core of the heater principle is energy conversion, and the most common is the conversion of electrical energy into thermal energy.
[0003] In the prior art, when a heater is used in a laboratory to heat chemical liquids, the heating temperature and heating pressure need to be controlled, and the pressure needs to be relieved when the pressure exceeds a threshold to prevent explosion. However, during the pressure relief, the evaporated chemical liquid will be discharged through the pressure relief port, which will not only cause harm to the environment and experimenters, but also cause the ratio of chemical raw materials inside the heater to change due to the different volatility of different chemical raw materials, affecting the experimental results. Therefore, we provide a liquid heater and a working method thereof. Summary of the invention

The heating box is made of waterproof heat-conductive material, arranged inside the heating tank, and fixedly connected to the bottom surface of the heating tank by bolts. A plurality of electric heating tubes are arranged inside the heating box and fixedly connected to the heating box by bolts. The detection tube is arranged horizontally, arranged at the top of the heating tank, horizontally penetrates the heating tank, and is fixedly connected to the heating tank. The axis of the adjustment column coincides with the axis of the detection tube, and is arranged inside the end of the detection tube away from the heating tank. The adjustment column is connected to the detection tube by threads, and a sealing rubber layer is arranged on the outer surface of the adjustment column. The display rod is a cylindrical rod, whose axis coincides with the axis of the detection cylinder, and passes through the adjustment column, and is slidably connected to the adjustment column, and the sliding direction of the display rod is parallel to the axis of the detection cylinder. The first piston is in the shape of an elongated strip and is made of heat-resistant rubber material. The axis of the first piston coincides with the axis of the display rod. The first piston is slidably arranged in the detection cylinder, on the side of the display rod close to the heating tank, and is fixedly connected to one end of the display rod, and the sliding direction of the first piston is parallel to the sliding direction of the display rod. The temperature sensor is arranged in the side wall of the heating tank. The pressure relief hole is arranged at the top of the detection cylinder, on the outside of the heating tank, corresponding to the first piston, and the pressure relief hole is connected to the detection cylinder. The sealing ring is sleeved on the display rod and is fixedly connected to the adjustment column. The sliding groove is horizontally arranged at the top of the detection cylinder and is parallel to the display rod, and the sliding groove passes through the pressure relief hole. The sliding piece is slidably arranged in the sliding groove, and its sliding direction is parallel to the display rod, and the pressure relief hole is closed. A sealing rubber layer is arranged on the surface of the sliding piece, and a connecting hole is arranged in the middle of the sliding piece. The connecting hole is located on the side of the pressure relief hole close to the heating tank, and the distance between the connecting hole and the pressure relief hole is the same as the sliding distance of the sliding piece. The heat expansion block is arranged in the sliding groove, on the side of the sliding piece close to the heating tank, one end of which is fixedly connected to the detection cylinder, and the other end is fixedly connected to the sliding piece. The recovery pipe is a hard pipe, which is arranged outside the heating tank, and one end is connected to the pressure relief hole. The storage box is arranged outside the heating tank, and the top of the storage box is connected to the other end of the recovery pipe. The cooling end of the cooler is arranged in the storage box, and the heat release end of the cooler is arranged outdoors. The piston box is arranged on the side of the storage box. The second piston is slidably arranged inside the piston box, and its sliding direction is arranged vertically. The hydraulic cylinder is vertically arranged on the top of the piston box, and the telescopic end of the hydraulic cylinder passes through the top of the piston box and is fixedly connected to the second piston, and the hydraulic cylinder is fixedly connected to the piston box. One end of the water suction pipe is connected to the bottom of the storage box, and the other end is connected to the bottom of the piston box. A first one-way valve is arranged inside the water suction pipe. One end of the water outlet pipe is connected to the bottom of the piston box, and the other end is connected to the top of the heating tank. A second one-way valve is arranged inside the water outlet pipe. A liquid level sensor is arranged inside the storage box.The controller is electrically connected with a plurality of electric heating tubes, a temperature sensor, a cooler, a hydraulic cylinder, a liquid level sensor, and an electric valve.
[0006] When the liquid needs to be heated, the staff adds the liquid to the heating tank, and then covers the sealing cover on the upper part of the heating tank to seal it. After that, the staff controls the electric heating tube to start through the controller, and the electric heating tube heats the liquid in the heating tank until the temperature sensor detects that the temperature reaches the set value. After that, the heat expansion block expands due to heat, pushing the sliding plate to slide, so that the connecting hole is connected with the pressure relief hole. As the liquid evaporates, the air pressure in the heating tank gradually increases, pushing the first piston to slide outward, and the first piston drives the display rod to move outward. At the same time, the first piston squeezes the air between the first piston and the adjusting column until the first piston exposes the pressure relief hole. At this time, the evaporated liquid in the heating tank will enter the storage box through the pressure relief hole, the connecting hole, and the recovery pipe in turn, and then be cooled and liquefied by the cooling end of the cooler into liquid and fall into the inside of the storage box. At this time, the staff can read the air pressure parameters in the heating tank through the display rod. When the liquid level sensor senses that the liquid in the storage tank has accumulated to a set height, the controller controls the hydraulic cylinder to reciprocate and extend once, and the hydraulic cylinder drives the second piston to reciprocate and extend once, and the second piston drives the liquid in the storage tank to return to the heating tank through the suction pipe, the first one-way valve, the piston box, the outlet pipe, and the second one-way valve in turn, so as to recover the liquid. When the heating of the liquid is completed, the staff controls the electric heating tube to close through the controller, and the temperature gradually drops, and the heat expansion block shrinks, driving the sliding plate to slide, and the pressure relief hole is closed. In this way, even if the evaporated liquid in the heating tank is cooled and liquefied, causing the air pressure in the heating tank to decrease, thereby causing the first piston to move inward and expose the pressure relief hole, the air between the first piston and the adjusting column will not be connected to the pressure relief hole, and it will be in a closed state, which can prevent the first piston from falling directly into the heating tank, limit the first piston, and will not affect the accuracy of the air pressure display of the display rod. When the staff needs to adjust the pressure relief air value, the staff rotates the adjusting column to move the adjusting column, and pushes or pulls the first piston to move through the air between the first piston and the adjusting column, so that the distance between the end of the first piston toward the heating tank and the pressure relief hole changes, thereby adjusting the pressure relief air value.
[0007] Furthermore, the thread on the inner side of the detection tube is a thread groove.
[0008] By setting the thread on the inner side of the detection cylinder as a thread groove, when the first piston needs to be installed, the adjusting column is first sleeved on the specified scale position of the display rod, and then the first piston and the adjusting column are inserted into the detection cylinder, and then the adjusting column is rotated for installation. In this way, the amount of air between the first piston and the adjusting column can be accurate, thereby making the air pressure display of the display rod more accurate and making installation and disassembly more convenient.
[0009] Furthermore, it includes an air pressure detection sensor, which is arranged in the storage box and fixedly connected to the inner top surface of the storage box. The air pressure detection sensor is electrically connected to the controller.
[0010] When the air pressure detection sensor detects that the air pressure in the storage box is higher than the set air pressure threshold, the controller controls the cooler to increase the power.
[0011] Furthermore, the controller includes a control panel and a display screen, and the display screen is arranged on the side of the heating tank and fixedly connected to the heating tank. The control panel is arranged on the side of the heating tank and fixedly connected to the heating tank, and the control panel is electrically connected to a plurality of electric heating tubes, a temperature sensor, a cooler, a hydraulic cylinder, a liquid level sensor, an electric valve, a display screen, and an air pressure detection sensor.
[0012] The staff can control the opening and closing of several electric heating tubes, coolers, hydraulic cylinders, electric valves, and display screens through the control panel. The display screen is used to display various parameters of the equipment.
[0013] Furthermore, it comprises a rotating handle, which is arranged outside the detection tube and along the radial direction of the adjustment column. The rotating handle is fixedly connected to the adjustment column, and a non-slip rubber layer is arranged on the surface of the rotating handle.
[0014] By providing a rotating handle, the adjustment column can be rotated more conveniently.
[0015] Furthermore, it includes a plurality of buffer blades, which are arranged in the recovery pipe, and the plurality of buffer blades are rotatably connected to the recovery pipe through a mounting frame, and the rotation axis thereof is arranged along the axis of the recovery pipe.
[0016] By arranging a plurality of buffer blades, the pressure relief airflow can be buffered and dispersed, thereby preventing the strong impact force generated by the pressure relief airflow from damaging the internal structure of the storage box.
[0017] Furthermore, it includes a trigger button and a pressing piece. The trigger button is arranged inside the recovery pipe and close to the pressure relief hole. The trigger button is fixedly connected to the recovery pipe, and the trigger button is electrically connected to the refrigerator. The pressing piece is arranged obliquely inside the recovery pipe, on the side of the trigger button close to the pressure relief hole, the side of the pressing piece is rotatably connected to the inner wall of the recovery pipe, and the pressing piece cooperates with the trigger button.
[0018] When the first pressure relief is performed, the pressure relief airflow will push the pressing piece to rotate, and the pressing piece presses the trigger button, and the trigger button controls the cooler to start automatically, thereby saving energy. The pressing piece cooperates with the trigger button, and the trigger button can be pressed after the pressing piece rotates.
[0019] Furthermore, it includes a plurality of supporting legs, which are made of heat-insulating materials, are arranged below the heating tank, and are fixedly connected to the bottom of the heating tank. The lower ends of the plurality of supporting legs are inclined outward, and the lower ends of the supporting legs are provided with anti-slip pads.
[0020] By providing a plurality of supporting legs, the device can be made more stable.
[0021] A working method for a liquid heater. When a staff member needs to adjust the pressure relief air pressure to a smaller value, the staff member turns a rotary adjustment column to move the adjustment column away from a heating tank, thereby reducing the air pressure between a first piston and the adjustment column. The first piston moves away from the heating tank under the action of the air pressure difference, thereby shortening the distance between the end of the first piston close to the heating tank and the pressure relief hole, thereby adjusting the pressure relief air pressure to a smaller value.
[0022] When the staff needs to adjust the pressure relief air pressure to a higher value, the staff turns the reverse rotation adjusting column to move the adjusting column toward the heating tank, thereby increasing the air pressure between the first piston and the adjusting column. The first piston moves toward the heating tank under the action of the air pressure difference, thereby increasing the distance between the end of the first piston close to the heating tank and the pressure relief hole, thereby increasing the pressure relief air pressure value.
[0023] Furthermore, when the staff needs to accurately adjust the pressure relief value, the staff first adds water to the heating tank, and then covers the sealing cover on the upper part of the heating tank to seal it. After that, the staff controls the electric heating tube to start through the controller, and the electric heating tube heats the liquid in the heating tank. As the water evaporates, the air pressure in the heating tank gradually increases, pushing the first piston to slide outward, and the first piston drives the display rod to move outward. At the same time, the first piston squeezes the air between the first piston and the adjusting column until the first piston exposes the pressure relief hole to relieve pressure. When the staff observes that the position of the display rod is stable, the air pressure parameter of the display rod is the pressure relief value at this time. The staff adjusts the adjusting column as needed until the air pressure parameter of the display rod shows the pressure relief value required by the staff.
[0024] Beneficial effects of the present invention: 1. When the liquid needs to be heated, the staff adds the liquid to the heating tank, and then covers the sealing cover to the upper part of the heating tank to seal it. After that, the staff controls the electric heating tube to start through the controller, and the electric heating tube heats the liquid in the heating tank until the temperature sensor detects that the temperature reaches the set value. After that, the heat expansion block expands due to the heat, pushing the sliding plate to slide, so that the connecting hole is connected with the pressure relief hole. As the liquid evaporates, the air pressure in the heating tank gradually increases, pushing the first piston to slide outward, and the first piston drives the display rod to move outward. At the same time, the first piston squeezes the air between the first piston and the adjusting column until the first piston exposes the pressure relief hole. At this time, the evaporated liquid in the heating tank will enter the storage box through the pressure relief hole, the connecting hole, and the recovery pipe in turn, and then be cooled and liquefied by the cooling end of the cooler into liquid and fall into the inside of the storage box. At this time, the staff can read the air pressure parameters in the heating tank through the display rod. When the liquid level sensor senses that the liquid in the storage tank has accumulated to a set height, the controller controls the hydraulic cylinder to reciprocate and extend once, and the hydraulic cylinder drives the second piston to reciprocate and extend once, and the second piston drives the liquid in the storage tank to return to the heating tank through the suction pipe, the first one-way valve, the piston box, the outlet pipe, and the second one-way valve in turn, so as to realize the recovery of the liquid. While being able to control the heating temperature and heating pressure, it is also possible to recover and return the liquid discharged by pressure relief.
[0025] 2. When the heating of the liquid is completed, the staff controls the electric heating tube to be closed through the controller. After the temperature gradually drops, the heat expansion block contracts, driving the sliding plate to slide and close the pressure relief hole. In this way, even if the evaporated liquid in the heating tank is cooled and liquefied, causing the air pressure in the heating tank to decrease, thereby causing the first piston to move inward to expose the pressure relief hole, the air between the first piston and the adjusting column will not be connected to the pressure relief hole, which is in a closed state. This can prevent the first piston from falling directly into the heating tank, limit the first piston, and will not affect the accuracy of the air pressure display of the display rod.
[0026] 3. When the staff needs to adjust the pressure relief air value, the staff rotates the adjusting column to move the adjusting column, and pushes or pulls the first piston to move through the air between the first piston and the adjusting column, so that the distance between the end of the first piston facing the heating tank and the pressure relief hole changes, thereby adjusting the pressure relief air value.

The first piston 25 is in the shape of an elongated strip and is made of heat-resistant rubber material. The axis of the first piston 25 coincides with the axis of the display rod 22. The first piston 25 is slidably arranged in the detection cylinder 2, on the side of the display rod 22 close to the heating tank 1, and is fixedly connected to one end of the display rod 22, and the sliding direction of the first piston 25 is parallel to the sliding direction of the display rod 22. The temperature sensor is arranged in the side wall of the heating tank 1. The pressure relief hole is arranged at the top of the detection cylinder 2, outside the heating tank 1, corresponding to the first piston 25, and the pressure relief hole is connected with the detection cylinder 2. The sealing ring is sleeved on the display rod 22 and fixedly connected with the adjustment column 21. The sliding groove is arranged horizontally at the top of the detection cylinder 2 and parallel to the display rod 22, and the sliding groove passes through the pressure relief hole. The sliding sheet 210 is slidingly arranged in the sliding groove, and its sliding direction is parallel to the display rod 22, and the pressure relief hole is closed. The surface of the sliding sheet 210 is provided with a sealing rubber layer, and the middle part of the sliding sheet 210 is provided with a connecting hole, which is located on the side of the pressure relief hole close to the heating tank 1, and the distance between the connecting hole and the pressure relief hole is the same as the sliding distance of the sliding sheet 210. The heat expansion block 26 is arranged in the sliding groove, on the side of the sliding sheet 210 close to the heating tank 1, one end of which is fixedly connected with the detection cylinder 2, and the other end is fixedly connected with the sliding sheet 210. The recovery pipe 24 is a hard pipe, which is arranged outside the heating tank 1, and one end is connected with the pressure relief hole. The storage box 3 is arranged outside the heating tank 1, and the top of the storage box 3 is connected to the other end of the recovery pipe 24. The cooling end of the cooler 32 is arranged inside the storage box 3, and the heat release end of the cooler 32 is arranged outdoors. The piston box 4 is arranged on the side of the storage box 3.The second piston 42 is slidably disposed inside the piston box 4, and its sliding direction is vertically disposed. The hydraulic cylinder 41 is vertically disposed on the top of the piston box 4, and the telescopic end of the hydraulic cylinder 41 passes through the top of the piston box 4 and is fixedly connected to the second piston 42, and the hydraulic cylinder 41 is fixedly connected to the piston box 4. One end of the water suction pipe 34 is connected to the bottom of the storage box 3, and the other end is connected to the bottom of the piston box 4, and a first one-way valve is disposed inside the water suction pipe 34. One end of the water outlet pipe 15 is connected to the bottom of the piston box 4, and the other end is connected to the top of the heating tank 1, and a second one-way valve is disposed inside the water outlet pipe 15. The liquid level sensor 31 is disposed inside the storage box 3. The controller is electrically connected to a plurality of electric heating tubes 12, a temperature sensor, a cooler 32, a hydraulic cylinder 41, a liquid level sensor 31, and an electric valve.
[0031] When the liquid needs to be heated, the staff adds the liquid to the heating tank 1, and then covers the sealing cover 16 on the upper part of the heating tank 1 to seal it. After that, the staff controls the electric heating tube 12 to start through the controller, and the electric heating tube 12 heats the liquid in the heating tank 1 until the temperature sensor detects that the temperature reaches the set value. After that, the heat expansion block 26 expands by heat, pushing the sliding sheet 210 to slide, so that the connecting hole is connected with the pressure relief hole. As the liquid evaporates, the air pressure in the heating tank 1 gradually increases, pushing the first piston 25 to slide outward, and the first piston 25 drives the display rod 22 to move outward. At the same time, the first piston 25 squeezes the air between the first piston 25 and the adjusting column 21 until the first piston 25 exposes the pressure relief hole. At this time, the evaporated liquid in the heating tank 1 will enter the storage box 3 through the pressure relief hole, the connecting hole, and the recovery pipe 24 in turn, and then be cooled and liquefied by the cooling end of the cooler 32 into liquid and fall into the inside of the storage box 3. At this time, the staff can read the air pressure parameters in the heating tank 1 through the display rod 22. When the liquid level sensor 31 senses that the liquid in the storage tank 3 has accumulated to a set height, the controller controls the hydraulic cylinder 41 to reciprocate and extend once, and the hydraulic cylinder 41 drives the second piston 42 to reciprocate and extend once, and the second piston 42 drives the liquid in the storage tank 3 to return to the heating tank 1 through the water suction pipe 34, the first one-way valve, the piston box 4, the water outlet pipe 15, and the second one-way valve in turn, so as to realize the recovery of the liquid. When the heating of the liquid is completed, the staff controls the electric heating tube 12 to be closed through the controller, and the heat expansion block 26 contracts after the temperature gradually decreases, driving the sliding sheet 210 to slide and close the pressure relief hole. In this way, even if the evaporated liquid in the heating tank 1 is cooled and liquefied, resulting in a decrease in the air pressure in the heating tank 1, thereby causing the first piston 25 to move inward and expose the pressure relief hole, the air between the first piston 25 and the adjusting column 21 will not be connected to the pressure relief hole, and it is in a closed state, which can prevent the first piston 25 from falling directly into the heating tank 1, limit the first piston 25, and will not affect the accuracy of the air pressure display of the display rod 22. When the staff needs to adjust the pressure relief air value, the staff rotates the adjusting column 21 to move the adjusting column 21, and pushes or pulls the first piston 25 to move through the air between the first piston 25 and the adjusting column 21, so that the distance between the end of the first piston 25 toward the heating tank 1 and the pressure relief hole changes, thereby adjusting the pressure relief air value.
[0032] The thread on the inner side of the detection tube 2 is a thread groove.
[0033] By setting the thread on the inner side of the detection cylinder 2 as a thread groove, when the first piston 25 needs to be installed, the adjusting column 21 is first sleeved on the specified scale position of the display rod 22, and then the first piston 25 and the adjusting column 21 are inserted into the detection cylinder 2, and then the adjusting column 21 is rotated for installation. In this way, the amount of air between the first piston 25 and the adjusting column 21 can be accurate, so that the air pressure display of the display rod 22 is more accurate, and installation and disassembly can be more convenient.

The pressing piece 27 is obliquely arranged inside the recovery pipe 24 and is located on the side of the trigger button 28 close to the pressure relief hole. The side of the pressing piece 27 is rotatably connected to the inner wall of the recovery pipe 24, and the pressing piece 27 cooperates with the trigger button 28.
[0043] When the first pressure relief is performed, the pressure relief airflow pushes the pressing piece 27 to rotate, and the pressing piece 27 presses the trigger button 28, and the trigger button 28 controls the cooler 32 to automatically start, thereby saving energy. The pressing piece 27 cooperates with the trigger button 28, and the trigger button 28 can be pressed after the pressing piece 27 rotates.

The lower ends of the four supporting legs 14 are inclined outward, and the lower ends of the supporting legs 14 are provided with anti-slip pads.
[0045] By providing four supporting legs 14, the device can be made more stable.
[0046] Working principle: When the liquid needs to be heated, the staff adds the liquid to the heating tank 1, and then covers the sealing cover 16 on the upper part of the heating tank 1 to seal it. After that, the staff controls the electric heating tube 12 to start through the control panel, and the electric heating tube 12 heats the liquid in the heating tank 1. After that, the heat expansion block 26 expands due to heat, pushing the sliding sheet 210 to slide, so that the connecting hole is connected with the pressure relief hole. As the liquid evaporates, the air pressure in the heating tank 1 gradually increases, pushing the first piston 25 to slide outward, and the first piston 25 drives the display rod 22 to move outward. At the same time, the first piston 25 squeezes the air between the first piston 25 and the adjusting column 21 until the first piston 25 exposes the pressure relief hole. At this time, the evaporated liquid in the heating tank 1 will enter the storage box 3 through the pressure relief hole, the connecting hole, the recovery pipe 24, the pressing sheet 27, and a number of buffer blades 29 in sequence. The pressure relief airflow will push the pressing sheet 27 to rotate, and the pressing sheet 27 presses the trigger button 28, and the trigger button 28 controls the start of the cooler 32. The evaporated liquid entering the storage tank 3 is cooled by the cooling end of the cooler 32 and liquefied into liquid and falls into the storage tank 3. At this time, the staff can read the air pressure parameters in the heating tank 1 through the display rod 22. When the liquid level sensor 31 senses that the liquid in the storage tank 3 has accumulated to a set height, the control panel controls the hydraulic cylinder 41 to reciprocate and extend once, and the hydraulic cylinder 41 drives the second piston 42 to reciprocate and extend once, and the second piston 42 drives the liquid in the storage tank 3 to return to the heating tank 1 through the water suction pipe 34, the first one-way valve, the piston box 4, the water outlet pipe 15, and the second one-way valve in turn, so as to realize the recovery of the liquid. When the heating of the liquid is completed, the staff controls the electric heating tube 12 to be turned off through the control panel. After the temperature gradually drops, the heat expansion block 26 shrinks, driving the sliding sheet 210 to slide and close the pressure relief hole. In this way, even if the evaporated liquid in the heating tank 1 is cooled and liquefied, resulting in a decrease in the air pressure in the heating tank 1, thereby causing the first piston 25 to move inward and expose the pressure relief hole, the air between the first piston 25 and the adjusting column 21 will not be connected to the pressure relief hole, and the pressure relief hole is in a closed state, which can prevent the first piston 25 from falling directly into the heating tank 1, limit the first piston 25, and will not affect the accuracy of the air pressure display of the display rod 22. When the staff needs to adjust the pressure relief value, the staff rotates the adjusting column 21 by turning the handle 23 to move the adjusting column 21, and the air between the first piston 25 and the adjusting column 21 pushes or pulls the first piston 25 to move, so that the distance between the end of the first piston 25 facing the heating tank 1 and the pressure relief hole changes, thereby adjusting the pressure relief value.
[0047] When the air pressure detection sensor 33 detects that the air pressure in the storage box 3 is higher than the set air pressure threshold, the control panel controls the cooler 32 to increase the refrigeration power.
[0048] When the first piston 25 needs to be installed, first put the adjusting column 21 on the specified scale position of the display rod 22, then insert the first piston 25 and the adjusting column 21 into the detection cylinder 2, and then rotate the adjusting column 21 for installation. This can make the air volume between the first piston 25 and the adjusting column 21 accurate, so that the air pressure display of the display rod 22 is more accurate, and can make installation and disassembly more convenient.
[0049] A working method of a liquid heater. When a staff member needs to adjust the pressure relief air pressure value to be smaller, the staff member rotates the adjusting column 21 by turning the handle 23 to move the adjusting column 21 away from the heating tank 1, so that the air pressure between the first piston 25 and the adjusting column 21 becomes smaller. The first piston 25 moves away from the heating tank 1 under the action of the air pressure difference, so that the distance between the end of the first piston 25 close to the heating tank 1 and the pressure relief hole is shortened, thereby adjusting the pressure relief air pressure value to be smaller.
[0050] When the staff needs to adjust the pressure relief air pressure to a higher value, the staff rotates the adjusting column 21 in the opposite direction by turning the handle 23 to move the adjusting column 21 toward the heating tank 1, thereby increasing the air pressure between the first piston 25 and the adjusting column 21. The first piston 25 moves toward the heating tank 1 under the action of the air pressure difference, thereby increasing the distance between the end of the first piston 25 close to the heating tank 1 and the pressure relief hole, thereby increasing the pressure relief air pressure value.
[0051] When the staff needs to accurately adjust the pressure relief value, the staff first adds water to the heating tank 1, and then covers the sealing cover 16 on the upper part of the heating tank 1 to seal it. After that, the staff controls the electric heating tube 12 to start through the control panel, and the electric heating tube 12 heats the liquid in the heating tank 1. As the water evaporates, the air pressure in the heating tank 1 gradually increases, pushing the first piston 25 to slide outward, and the first piston 25 drives the display rod 22 to move outward. At the same time, the first piston 25 squeezes the air between the first piston 25 and the adjusting column 21 until the first piston 25 exposes the pressure relief hole to relieve pressure. When the staff observes that the position of the display rod 22 is stable, the air pressure parameter of the display rod 22 is the pressure relief value at this time. The staff adjusts the adjusting column 21 as needed until the air pressure parameter of the display rod 22 is displayed as the pressure relief value required by the staff.
[0052] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
