How to prevent gas tank explosion
A gas tank is also called a wind bag. In short, it is called by different names in different industries, but in the final analysis, its function remains the same. of. Purchasing a gas tank costs a lot of money, but if it is not carefully protected, the harm it will cause is immeasurable.
The following is a display of different types of gas storage tanks:

The consequences of the gas storage tank explosion:
p>
First of all, we must understand that the gas storage tank itself is a pressure vessel. Everyone has studied high school physics and knows that there must not be too high temperature and too high pressure inside the pressure storage, otherwise it will cause an explosion. The explosion of a pressure vessel can be scary.
In order to prevent danger to people and property caused by explosions, corresponding protective measures should be taken.
Method 1:
Install a pressure relief valve to physically protect it. Under a certain pressure, the pressure relief valve is impacted out, physically releasing the pressure of the wind bag.
Method 2:
Install a comprehensive protection device for the air compressor and conduct "macro-control" of the pressure and temperature. If the pressure and temperature of the gas storage tank are too high, the device will need to be modified. It will sound and light alarm and stop operation to protect the safety of gas storage tank and air compressor. (While this seems simple, there is actually a difficulty, which is how to accurately test the temperature and pressure of the gas storage tank. Each manufacturer has its own unique method)
Method three:
Double protection, physical Although the explosion can release the pressure in the gas tank, the accumulation of impurities inside the gas tank occasionally affects the normal release of the pressure relief valve. In this way, the delayed explosion will cause personal safety hazards. Danger.
So double protection is the safest approach.
Detailed explanation of frequently asked questions:
1. As long as it is a gas storage tank, no matter what model it is, can a pressure relief valve or comprehensive air compressor protection be installed?
Answer: Yes, different gas storage tanks require different types of pressure relief valves. The installation of the air compressor comprehensive protection device is based on the model of the air compressor.
2. What material is the best for the pressure relief valve?
Answer: The piston barrel is made of stainless steel, the protective cover is made of carbon steel, and the flange is made of national standard cast steel.

4. What types of pressure relief valves are there?
Answer: QHF50, QHF65, QHF80, QHF100, QHF150, QHF200, QHF250, QHF125, choose the corresponding model according to the size of the gas storage pipe diameter.
5. What are the models of comprehensive protection devices for air compressors?
1)KZB-Ⅰ type air compressor comprehensive protection device (white, double screen) one air protection for one screw air compressor
2)KZB-Ⅲ type air compressor Compressor comprehensive protection device (black) one air protection for one piston air compressor
3) KZB-PC-III centralized control air compressor wind bag comprehensive protection device (pressure, temperature , pressure relief) One air protector protects multiple air compressors
4) KZB-PC centralized air bag comprehensive protection device One air protector protects four air compressors
6. How to choose the right manufacturer?
Answer: When choosing a manufacturer, you need to pay attention to the following points: 1) Product quality certificate; 2) One-year warranty statement: 3) Inspection report; 4) Installation instructions; 5) If it is Shanxi, Shanxi Designated manufacturer certificate (to avoid unnecessary duplication of purchases when the supervisory agency explicitly orders which unit) 6) Patent certificate
