Some users of transport-type small four-wheel tractors installed the safety valve and the discharge valve on the air reservoir in the pneumatic brake device. That is, the discharge valve was installed at the right end of the air reservoir (equivalent to blockage), and the safety valve was installed below the air reservoir. The user exchanges in such a way that the water and oil accumulated in the air reservoir do not need to be opened by opening the drain valve switch, but is discharged together with the air vents on the safety valve. This practice is very wrong. First, the user must have a clear understanding of the role of the safety valve and the drain valve. The safety valve is composed of a valve body, a spring, a steel ball and a bolt, and the pressure of the pneumatic brake system is ensured to not exceed the prescribed pressure value by adjusting the pressure of the spring to ensure safety. In order to maintain its working performance and easy adjustment, it is installed in the middle of the right end of the air reservoir. The drain valve is mainly used to discharge the accumulated water and oil in the air reservoir, preventing the oil from entering the brake valve and the wheel brake air chamber, and affecting the braking performance. It is usually installed at the bottom of the air reservoir and requires the user to periodically open the drain valve according to work conditions. If the two are replaced, the safety valve will discharge air and oil at the same time. The dirt, such as water and oil, will adhere to the steel ball, the spring and the valve body surface, affecting the sealing performance; and the exhaust hole below The springs are soaked in oil and water for a long time and are extremely corrosive, which seriously affects the performance of the safety valve. Therefore, the author suggests that the user should freely exchange the installation positions of the two, and do not use the safety valve to replace the role of the drain valve.
