Safety valves play a crucial role in the operation of high-pressure washers. It is divided into two types: pneumatic safety valve and burst membrane safety valve, among which the working mechanism of the burst membrane safety valve is quite ingenious. When the system pressure exceeds the set warning pressure, it discharges the water, and the burst membrane is part of this mechanism"Weak points"。When the pressure exceeds the design pressure of the system, the rupture membrane will burst in response, like a guardian system"Goalkeeper"。
The safety valve is installed at the discharge end of the pump and is equipped with a spring and valve manifold mechanism. The spring presets the spool in the closed position. When the pressure of the high-pressure water pump exceeds a predetermined value, this valve opens automatically. This action expels a portion of the gas from the system into the atmosphere, ensuring that the system pressure does not exceed the permissible value. In this way, the high-pressure water cleaning operation can be carried out efficiently and safely.
It is worth noting that although the working principle of ultra-high pressure washer is similar to that of a high-pressure washer, the rated pressure value of its equipment is higher, and it is mainly used to remove stubborn dirt. Safety valves are particularly important due to the relatively high hazards associated with ultra-high pressures.
When purchasing an ultra-high pressure cleaner, in addition to confirming whether the equipment is equipped with a safety valve, users should also compare multiple parties to measure the reliability of the equipment safety valve from multiple perspectives such as operation mode, design principle, and hardware quality. The safety valve of the ultra-high pressure washer adopts the burst membrane type, which is both safe and reliable. Moreover, the diaphragm has become a standard part, further enhancing the performance of the equipment. In addition, the core components of the equipment, such as high-pressure pumps, safety valves, and pressure regulating valves, are mostly imported from Europe and the United States, which provides a strong guarantee for the safe and reliable operation of the ultra-high-pressure cleaner.
