Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following are the top ten domestic first-line valve brand manufacturers in 2022-2023, but for reference only: Suzhou Neway Valve Co., Ltd., Shanghai Guanlong Valve Machinery, Shanghai Qizhong Valve Manufacturing, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

The working principle of the explosion-proof flame retardant breathing valve is to use a spring limit valve plate, which is determined by positive and negative pressures or exhalation or inhalation. The breathing valve should have two functions: positive pressure and negative pressure, specifically: when the container is subjected to positive pressure, the breathing valve opens the exhaled air to release positive pressure; When the container is subjected to negative pressure, the flame retardant breathing valve opens the suction gas to vent the negative pressure.

This ensures that the pressure is within a certain range and the container is safe.

What is the difference between a pressure explosion proof valve and a breathing valve, you are asking? The differences between the two are as follows:

1. The principle is different: the pressure explosion-proof valve is a safety valve, which is used to control the pressure inside the container, when the internal pressure of the container exceeds the set value, the valve will automatically open and release the pressure to avoid the container. A breathing valve is a type of breather valve that is used to control the pressure and temperature of the gas inside the container to avoid too high or too low pressure inside the container.

2. Different functions: The pressure explosion-proof valve is usually installed on the top or side of the container, and can be selected according to the design pressure and temperature of the container. Breathing valves are usually mounted on the top or side of the vessel and can be selected according to the design pressure and temperature of the vessel.

The breathing valve also prevents the vacuum formation of the Sakura part of the container, ensuring the normal circulation of the gas inside the container.

1) The breathing valve should be installed at the highest point of the gas source of the hail silver storage tank to reduce the evaporation loss of the material and smoothly provide the most direct and largest passage to the breathing valve. Usually for vertical tanks, the breathing valve should be installed as far as possible within the top of the tank, and for the tank top storage tank that needs to be insulated, it can be installed near the ladder platform;

2) When two breathing valves need to be installed, they should be arranged symmetrically with the center of the tank top;

3) If the breathing valve is used on the nitrogen-sealing tank, the pipe position of the nitrogen gas supply pipe should be far away from the breathing valve interface, and inserted into the storage tank about 200mm from the top of the tank, so that the nitrogen will not be directly discharged after entering the tank, so as to achieve the purpose of blanketing.

The working principle of explosion-proof flame retardant breathing valve is to use a spring limit valve plate, which is determined by positive and negative pressure, or exhale or inhale. The breathing valve should have two functions: positive pressure and negative pressure, specifically: when the container is subjected to positive pressure, the breathing valve opens the exhaled air to release positive pressure; When the container is subjected to negative pressure, the flame retardant breathing valve opens the inhalation gas to release the negative pressure.

This ensures that the pressure is within a certain range and the container is safe.

The explosion-proof flame retardant breathing valve is a product that combines the breathing valve and the flame arrester, and its principle is to add the explosion-proof flame-retardant corrugated disc, the core component of the flame arrester, at the respiratory mouth of the breathing valve. Its function is consistent with the function of the breathing valve, which can ensure the safety performance of the storage tank while playing the function of the breathing valve.

Explosion-proof flame retardant breathing valve is a safe and energy-saving product to maintain the air pressure balance of the storage tank and reduce the volatilization of the medium, the explosion-proof flame retardant breathing valve makes full use of the pressure bearing capacity of the storage tank itself to reduce the medium discharge, and its principle is to use the weight of the positive and negative pressure valve disc to control the positive pressure of the exhaust and the negative suction pressure of the tank. When the pressure of the medium in the tank is within the range of the controlled and controlled operating pressure of the explosion-proof fire-retardant breathing valve, the explosion-proof flame-retardant breathing valve does not work to maintain the tightness of the oil tank; When the medium is added to the tank, the pressure of the upper gas space in the tank is increased, and the positive pressure of the explosion-proof fire-retardant breathing valve is reached, the pressure valve is opened, and the gas escapes from the exhalation port of the explosion-proof fire-retardant breathing valve, so that the pressure in the tank does not continue to increase; When the medium is withdrawn to the outside of the tank, the pressure of the upper gas space in the tank drops, and the negative pressure of the explosion-proof fire-retardant breathing valve is reached, the atmosphere outside the tank will open the negative pressure valve disc of the explosion-proof fire-retardant breathing valve, so that the outside gas enters the tank, so that the pressure in the tank rock lifting bureau does not continue to fall, so that the air pressure inside the tank and outside the tank is balanced, so as to protect the safety device of the storage tank, and the exhaled and inhaled gas needs to pass through the explosion-proof fire-retardant corrugation, which can prevent the fire source from entering the storage tank.

The explosion-proof flame retardant breathing valve integrates the flame arrester and the breathing valve, and its novel structure is the first in China. It is a new type of safety equipment necessary for petrochemical storage tanks, and its biggest advantages are good fire retardant breathing performance, light weight and easy maintenance.

The anti-aging and explosion-resistant fire retardant breathing valve is suitable for storing Class A oil with an inner point of less than 28 and Class B oil with a flash point of less than 60, such as gasoline, benzene, toluene, coal oil, light diesel oil, engine oil, ** and other oil products and chemical products with the same nature, and it works normally in a temperature environment of -35 -60.
