I. Brief introduction of single call valve

   是指人体呼吸是指机体与外界环境之间气体交换的过程。 Single call valve refers to the process of human body breathing, which is the process of gas exchange between the body and the external environment. The human breathing process includes three interconnected links: external breathing, including lung ventilation and lung ventilation; gas transportation in the blood; internal breathing, which refers to the gas exchange between tissue cells and blood. This type of valve should generally be installed horizontally in the pipeline.


广义概念 Second, the broad concept of single call valve

Normal adults breathe 16-20 breaths per minute when they are quiet. The amount of gas inhaled and exhaled each time is about 500 ml, which is called tidal volume. When a person inhales hard until they can no longer inhale; then exhales harder until they can no longer exhale. The amount of exhaled air at this time is called vital capacity. Normal adult male lung capacity is about 3500-4000 ml, and female is about 2500-3500 ml. Spirometry represents the size of a person's potential breathing ability. It can reflect a person's breathing function and health to some extent. It is one of the commonly used methods for measuring breathing work. The respiratory system consists of the snorkel and throat air ducts, two lungs, and a long trachea that connects the throat and lungs. The bottom of the trachea is divided into two bronchi, each of which is connected to one of its lungs. 呼吸阀 首先是细支气管,然后是终末细支气管。 The bronchi are subdivided into smaller trachea. The breathing valve is first the bronchioles and then the terminal bronchioles. At the end of the terminal bronchioles are small air-filled packets called alveoli.

Aerobic respiration: C6H12O6 + 6H2O + 6O2—— → 6CO2 + 12H2O + energy (most organisms)

Anaerobic respiration: C6H12O6— → 2C2H5OH + 2CO2 + energy (most anaerobic respiration of higher plants, yeast, etc.)

Or: C6H12O6— → 2C3H6O3 + energy (animals, lactic acid bacteria, potato tubers, beet roots, corn embryos, etc.)

This term is used to describe some phenomena that are closely related but somewhat different in meaning. Such as:

(1) Two breathing exercises.

(2) The phenomenon that animals inhale molecular oxygen from the outside world and release carbon dioxide to the outside world to perform gas exchange through breathing exercises. This is called exobreathing.

(3) The phenomenon that cells absorb oxygen and emit carbon dioxide is called cell respiration. In many animals, the oxygen inhaled through the outer breath is transported to the cells and tissues of the body for consumption, so this corresponds to the outer breath and is called the inner breath.

(4) The biochemical change that is the basis of cellular respiration, that is, respiratory metabolism. It can be divided into several stages from narrow to broad:

(a) In the narrowest sense, with the participation of molecular oxygen, organic matter is completely decomposed into inorganic substances such as carbon dioxide, water, ammonia, etc., and supplies energy, and the energy available to the organism (mainly ATP).

(b) Including (a) above, the most common definition is that cells absorb molecular oxygen and produce all oxidation processes. In this sense, breathing intensity is expressed as the volume of oxygen absorbed by a certain amount of substance per unit time, usually expressed as QO2. When organic matter is used as the breathing matrix (breathing material); the volume ratio between the amount of carbon dioxide emitted and the amount of oxygen absorbed is called the respiratory quotient (RQ).

(c) The definition of (b) is further expanded to include the process of replacing oxygen with nitrate, sulfate, etc. as the final electron acceptor to obtain energy under anaerobic conditions. These processes are called nitric acid, respectively. Respiration, sulfuric acid respiration.

单吸阀 凡通过氧化还原获得能量的过程,都称为呼吸。 (d) The broadest definition refers to the chemical dark reaction. The process of a single suction valve to obtain energy through redox is called breathing. At this time, oxygen becomes the final electron acceptor, and the above-mentioned process of b is specifically called aerobic breathing or aerobic breathing, and the others are called anaerobic breathing or anaerobic breathing. Alcoholic fermentation and glycolysis also belong to anaerobic breathing in this sense. Fermentation is an oxidation-reduction reaction between the compounds produced by the substrate. In this case, it can be called intramolecular respiration. The breathing mechanism is generally regarded as the change of organic matter and the electron transfer process in the dehydrogenation reaction.

Normal breathing: The ratio of breathing to pulse is 1: 4. Men and children are mainly dominated by abdominal breathing, while women are dominated by chest breathing.

单呼阀工业设备 Third, single call valve industrial equipment

   principle

The check valve is generally installed horizontally in the pipeline. The single call valve makes full use of the pressure bearing capacity of the oil tank to reduce oil vapor emissions. The principle is to use the weight of the valve disc to control the positive pressure and negative pressure of the oil tank. 充分利用油罐本身的承压能力来减少油蒸气排放,使罐内的压力不在继续。 The single call valve makes full use of the pressure capacity of the oil tank itself to reduce oil vapor emissions, so that the pressure in the tank does not continue.

   effect

It makes full use of the pressure capacity of the oil tank itself to reduce oil vapor emissions, so that the pressure in the tank does not continue to decrease.

单呼阀 维护与保养 Fourth, single call valve maintenance

First of all, we must know that the necessary maintenance and maintenance is not only to ensure the safe operation of industrial production, but also to extend the service life of the breathing valve. Second, to understand the steps of maintenance and maintenance: maintenance is usually performed once a month, and in winter we will average one Twice a month
Maintenance method: After the valve cover is opened, take out the vacuum valve disc and pressure valve, and then check whether the valve disc seal, the guide rod, etc. are contaminated with oil or stolen materials. And check whether it is secure; of course, if the valve disc is scratched or cracked during use, it should be replaced immediately or contact the supplier;

单呼阀 优势 Five, single call valve advantages
 
呼吸阀 的总类不断细化,它也将会根据自身设计不同被应用于不同的行业,为更多的工业生产提供安全的保障。 It has the advantages of compact structure, small leakage, good sealing performance, and easy cleaning. With the continuous refinement of the general category of breathing valves , it will also be applied to different industries according to its own design, providing more industrial production Guarantee of safety.
