What are the design requirements of the high-pressure reactor?
The design requirements of the high-pressure reaction device (taking the high-pressure reaction kettle as an example) are as follows: ** 1. Determination of parameters ** 1. ** Pressure and temperature design ** - If the user provided the highest working pressure and working temperature, the type and form of the discharge device should be determined according to the material nature, and then the design pressure and design temperature of the reactor should be determined according to the relevant requirements of the high-pressure discharge device in the annex of the Steel Pressure Vessel. 2. ** Volume of high-pressure reactor ** - The volume is divided into full volume and effective volume. Usually, the user provides the effective volume. The staff must determine the material filling factor according to the safety production standards and control it to 0.5 - 0.95. For the reaction kettle with a flange-structure container, the material filling height cannot be higher than the sealing surface of the flange-structure container. 3. ** Type of shaft seal confirmed ** ** 2. Satisfy the requirements for production ** The high-pressure reactor used in the refinery should be able to withstand the pressure and temperature required in the production process, and have the specifications and structure required for the production process. ** 3. In terms of reliability ** 1. The chemical production materials were corrosive, toxic, flammable, explosive, and so on. When the reactor worked, it stored energy inside. Once it was destroyed, the energy would be released in a short period of time, causing damage. Therefore, it was necessary to ensure reliable exchange operation. 2. To ensure the designed service life. Since the chemical raw materials have corrosive effects on the shell material of the reactor equipment, additional corrosion allowance should be considered during the design to meet the service life requirements. ** 4. In terms of convenience ** The manufacturing, inspection, installation, operation, and maintenance must be convenient. The quality of equipment with simple structure, easy manufacturing and flaw detection is easy to guarantee, and it is easy to find and eliminate defects exceeding the standard. For test vessels whose top cover needs to be disassembled frequently, a quick-disassembled sealing structure should be adopted. Read more exciting novels for free

Low pressure 107, high pressure 155, need to take medicine
If the low pressure is 107 mm of mercury and the high pressure is 155 mm of mercury, this has already reached the standard of high blood pressure (a blood pressure of 140 - 159 mm of mercury and/or a blood pressure of 90 - 99 mm of mercury is considered to be Grade 1 high blood pressure, and a blood pressure of 160 mm of mercury and above or a blood pressure of 100 mm of mercury and above is considered to be Grade 2 high blood pressure). Generally speaking, this kind of situation might require medication, but other factors needed to be considered. First of all, if it was the first time that the blood pressure was found to be elevated, it should be ruled out whether there were inaccurate measurements, such as whether there was a full bladder (holding urine), sitting posture (sitting sideways), arms hanging in the air or raised during the measurement, cuffs on clothes, cuffs too small and tight, crossed legs (crossing legs), talking during the measurement, etc., which may cause the blood pressure reading to be high. If it was because of these factors that caused the blood pressure to rise, the blood pressure might return to normal after correction, so there was no need to take medicine. Secondly, if people with pre-high blood pressure (120 - 139 mm <anno data-annotation-id ="000000110 - 400a-411a-425a-800a-9999999999999"> contractile blood pressure </anno> and/or 80 - 89 mm </anno> dilated blood pressure </anno>) found that their blood pressure had reached this value for the first time and had not undergone lifestyle adjustment before, they could try lifestyle adjustment for 1 - 3 months, including low-salt and low-fat diet, smoking and alcohol restriction, weight loss, not staying up late, not tired, maintaining a happy mood, etc., and monitor their blood pressure regularly. If their blood pressure still did not drop, they needed to consider medication. However, if the blood pressure is still at this level after lifestyle adjustment, or if it is accompanied by target organ damage (such as heart, brain, kidney and other organ damage), diabetes, cardiovascular disease, etc., it is usually necessary to take anti-inflammatory drugs under the guidance of a doctor. In addition, special types of high blood pressure such as white coat high blood pressure (high blood pressure when checked in the hospital, but normal blood pressure when measured at home, and no target organ damage was found) did not need to take drugs, but if it was true high blood pressure (high blood pressure measured at home and in the hospital), medication should be considered. It is recommended to go to a regular hospital to see a doctor, determine the type of high blood pressure, and use the medicine reasonably according to the doctor's advice. Do not blindly take the medicine on your own. While waiting for the TV series, you can also click on the link below to read the classic original work of "Dafeng Nightwatchman"!

Shandingzi treats high blood pressure
Cassia was a type of traditional Chinese medicine that had the effects of lowering blood pressure, blood fat, and blood sugar. It was also rich in vitamins and trace elements, which could effectively soften blood vessels, help lower blood pressure, and prevent cardiovascular diseases. However, the effect of drinking the water of the mountain spicule was relatively limited. It could only help lower blood pressure and could not replace medication to treat high blood pressure. Patients with high blood pressure needed to be treated with medication under the guidance of a doctor to prevent their blood pressure from continuing to rise, causing the patient to have adverse symptoms. In addition, the patient could also perform appropriate cardiovascular exercise in their daily life, such as swimming and jogging, which could help improve high blood pressure.
