Variable angle Nozzle With Hi.-Lo. Function Suppliers

Basic principle of high-low pressure switching
The variable angle nozzle with hi.-lo. function introduces an internal channel switching mechanism that can adjust the spray pressure in its structural design. The high-pressure state usually corresponds to occasions with strong cleaning requirements, requiring greater water flow speed and impact force, while the low-pressure state is suitable for detergent spraying or pressure-sensitive surfaces. In this type of nozzle, the switching of high and low pressure functions is mainly achieved by manually operating the control valve, internal paddle or knob. When the user switches to high-pressure mode, the water flow will pass through the nozzle aperture at high speed in the most direct path; when switching to low-pressure mode, the water flow is guided through a bypass channel or an additional diffuser, thereby reducing the flow rate and pressure.

The impact of internal structure on high-low pressure switching
The key to achieving high-low pressure switching lies in the fluid control structure inside the nozzle. Ningbo Baige Machinery Manufacturing Co., Ltd. uses a variety of pressure regulation mechanisms in its nozzle products, including controllable valve cores, switching plates or spring return components. These devices can quickly change the path and cross-sectional area of ​​the water flow after the user operates it, thereby controlling the output of the water pressure. Under low pressure, the nozzle usually limits the pressure by expanding the water flow channel or setting a check valve, while under high pressure, the valve opens to allow the water to flow directly through the outlet with minimal resistance, forming a more concentrated and more impactful spray effect.

Common operation methods for high and low pressure switching
When the user switches the high and low pressure functions of the nozzle, the internal conversion of the structure is generally achieved by rotating the nozzle housing, pushing a button or toggling a switch. The various nozzle products designed by Ningbo Baige Machinery Manufacturing Co., Ltd. are often equipped with visual indicator marks to facilitate users to judge the current spray mode. In some models, a spring pressure device is used to make the operation smoother and can be switched stably under different water pressure conditions. In addition, some products are also equipped with quick-connect devices for easy combination with other cleaning equipment, making it safer and more convenient to switch the high and low pressure functions of the nozzle.

The role of high and low pressure functions in different applications
In actual applications, the high and low pressure functions of the nozzle are widely used in multiple cleaning scenarios. The high-pressure function can be used for deep cleaning of dirty areas on the surface of vehicle chassis, mechanical parts, walls, etc.; the low-pressure function is often used for gentle cleaning of the body surface, glass or home environment, as well as for pretreatment before chemical cleaning agents or foam spraying. The variable-angle high-low function nozzles produced by Ningbo Baige Machinery Manufacturing Co., Ltd. are widely used in equipment such as cleaning machines, foam sprayers, and telescopic spray rods. They are practical in both industrial and civil cleaning, especially in working environments with frequent rapid switching needs, and can better play the value of their pressure regulation function.

Synergistic relationship between angle adjustment and high-low pressure switching
Angle adjustment and high-low pressure switching are often designed in linkage, forming a complementary role in cleaning operations. The adjustable angle design allows the nozzle to adjust the direction of the water flow according to the target cleaning area, while the high-low pressure switching further adjusts the water flow intensity and contact mode. This linkage improves the adaptability of the nozzle in complex environments. For example, when cleaning the wheel hub of a vehicle, the user can adjust the angle to facilitate deep penetration into the gap, while switching to high pressure to remove scale; when rinsing the painted surface, it is adjusted to a low-pressure angle state to reduce the impact on the surface. Ningbo Baige Machinery Manufacturing Co., Ltd. is based on this demand and continuously improves the structural design of its nozzle products to coordinate the two functions in actual use.

The supporting role of materials and manufacturing processes on the pressure switching mechanism
The high and low pressure switching mechanism of the nozzle has high requirements on the stability and processing accuracy of the material. Ningbo Baige Machinery Manufacturing Co., Ltd. uses corrosion-resistant and water pressure-resistant engineering plastics and stainless steel components in product production to ensure the stable operation of the internal mechanism under frequent switching and high-intensity use conditions. At the same time, precision injection molding and turning processes can ensure the assembly accuracy of each key component, thereby avoiding switching failures due to loose parts, deformation and other problems. This emphasis on manufacturing quality directly affects the smoothness and life of the nozzle switching in actual operation.

System compatibility with cleaning equipment
The premise of realizing the high and low pressure switching function of the nozzle also lies in its interface compatibility with the high-pressure cleaning system or foam system. Ningbo Baige Machinery Manufacturing Co., Ltd.'s nozzle products are widely compatible with the mainstream quick-connect interface systems on the market, such as 1/4 inch, M22, G1/2 and other specification interfaces, which are convenient for integration with other accessories such as cleaning guns, water pipes, and hose reels. Good system compatibility not only facilitates users to quickly replace, but also ensures that other parts of the system will not have pressure relief, water leakage and other faults when the water pressure is switched, thereby improving the stability of the entire operating system.

Precautions in daily use and maintenance
Although the nozzle has the function of high and low pressure switching, to maintain its stability and effectiveness for a long time, it is also necessary to pay attention to regular cleaning of the internal channels of the nozzle to prevent scale or impurities from clogging the switching mechanism. Ningbo Baige Machinery Manufacturing Co., Ltd. clearly states in the user instructions that long-term use in extreme water quality or high temperature environments should be avoided, and key components should be disassembled and cleaned when necessary. Reasonable use and maintenance can extend the life of the nozzle, maintain the sensitivity of the switching function and the spraying effect, especially in high-frequency use environments.
