The quality of a truck's performance is closely related to its braking system. While problems with the engine and transmission can cause a vehicle to become inoperable, malfunctions in the braking system during operation can often result in irreparable consequences. Many of these parts require the use of pumps and valves.

Today Hantang Machinery will share with you several common valve truck accessories and their quality assessment experience.

1.Four-circuit protection valve

Four-circuit protective valve is a safety valve used in high-pressure gas system pipelines in automobiles, usually in automobile engine control systems and other high-pressure gas usage systems. When a circuit experiences a malfunction, such as leakage or overpressure, the four-circuit protective valve will automatically open to ensure that the engine and other systems are not affected, thereby protecting the normal operation of the vehicle.

2.Double H valve

(1) It maintains independent gas paths to avoid interference between different circuits and ensures normal vehicle operation.

(2) When a circuit experiences a leak or overpressure, the double H valve automatically opens to protect the engine and other systems from being affected.

(3) The double H valve also serves as a buffer to reduce the impact experienced by the vehicle during operation.

3.Brake master cylinder

By utilizing the vacuum created by the engine and the hydraulic principle, the brake pedal is converted into a force ratio between the brake pads and brake disc, thereby increasing braking efficiency and reducing vehicle stopping distance. It connects to the fuel tank, hoses, and the brake pedal, serving to transport and store brake fluid.

Quality judgment experience for these three types of valves:

First of all, you can judge the quality from the appearance. Products with fine workmanship have higher quality.

Secondly, the quality of valve products largely depends on the material of internal seals, such as the seal ring in a four-circuit protective valve. Natural rubber is used for its good sealing performance, resistance to oil and gas leakage, corrosion resistance, and other properties.

Finally, in practical applications, judging the quality of product, such as the brake master cylinder, through testing and usage after installation, we can determine the quality of the product. If during testing the brake pressure gauge in the driver's compartment drops significantly after pressing the brake once, it may indicate that the purchased brake valve has a gas leakage problem. You need to carefully check whether there is any gas leakage at the root of the piston in the master cylinder, and repair it by replacing the sealing ring or other methods.

Of course, when purchasing products, it is still important to choose a professional supplier. If you encounter the above-mentioned issues, these companies generally have technical teams that can provide you with video support or replace the product for you directly.

After the Chinese New Year, our company has optimized our work systems by consolidating resources from the technical department, procurement department, and business department, resulting in improved efficiency in various aspects of the company. This has guaranteed smooth communication with all our clients.

Han Tang Machinery, looking forward to win-win cooperation with you!
