Product Description 1. Product OverviewIntroducing the HA005-4X-10/16Q Pressure Differential Principle Check Valve, a pioneering patented product that our company, Huhang Technology Group Co., Ltd., has meticulously developed.Our state-of-the-art product is specifically designed to serve as a robust barrier at the cross-connection points between domestic drinking water and non-drinking water pipelines, ensuring the prevention of backflow contamination and maintaining the purity of the medium.1)Built on a pressure differential principle, it guarantees zero backflow, providing unmatched reliability;2)Ingenious design that incurs no pressure reduction at the inlet, leading to an impressive 25% energy saving;3)A true mark of innovation with dual-chamber control for superior performance;4) Featuring all internal components crafted from high-quality stainless steel or copper alloy, ensuring a completely pollution-free operation;5) A compact, straight-through structure that not only saves space but enhances efficiency;6) This remarkable invention is protected under patent number ZL 2013 1 0718280.5and utility model patent ZL 2013 2 0855732.X, underscoring its uniqueness and innovativeness.2. Technical Parameters3. Operating Principle1)The seamless opening and closing mechanism of the main valve in the pressure differential principle check valve is a marvel of engineering..As the valve supplies water downstream, the outlet's gate valve automatically opens, and water from the middle chamber cascades through the outlet. This results in a decrease in pressure P2. At this juncture, the left-side pressure P1 of the elbow piston triumphs over the spring's right-side pressure (PZh), prompting the piston to glide rightward, simultaneously activating the main valve with the quick-opening valve disc. Hence, the inlet valve must counteract the additional spring resistance. The medium then smoothly flows from the valve disc's outer sides into the middle chamber, efficiently supplying downstream water. As flow intensifies, P2 diminishes further, propelling the piston right until the main valve is completely open.Conversely, when downstream water supply ceases, the outlet's water supply valve shuts. This action causes the middle chamber's pressure to climb, nudging the piston leftward as depicted in circle 3, achieving a complete closure.2) This section explores the operation of the drain valve within the pressure differential principle check valve.Aligned with the national standard: 'When P1-P2 is at 14 KPa, the drain valve is programmed to open automatically, ensuring drainage. With a continuous decrease in pressure difference P1-P2, the drain valve remains open, draining thoroughly until fully open, leaving the middle chamber empty, forming a protective air gap between the inlet chamber and the middle chamber.'The drain valve operation results in a pressure drop P2. When P1-P2 falls below 14 KPa, the drain valve promptly closes, effectively thwarting any potential backflow of the medium.Should P1 persistently decline under the described conditions, the drain valve will remain open until fully extended, evacuating the middle chamber to create an empty void. This fosters a necessary air gap between the inlet chamber and the middle chamber, ensuring absolute prevention of backflow under all operational conditions.4.Typical Installation SchematicCompany ProfileHuhang Technology Group Co., Ltd. stands as a pioneering force in the industry, showcasing over two decades of unrivaled expertise in multi-specialty solutions.
