The card sleeve angle return water locking valve is a specialized protective valve accessory designed for heating, hot water, and fluid circulation systems. It is made of HPb 59-1 high-quality brass as the core raw material, integrating the convenience of card sleeve connection with the spatial adaptability of the angle structure. It has multiple functions such as return water locking, anti backflow, passive intelligent control, etc. It can automatically lock and open without the need for external power supply, and is widely suitable for civilian heating, boiler systems, solar hot water, central air conditioning and other scenarios. It is particularly suitable for installation positions with narrow pipeline corners and spaces, taking into account anti backflow, precise linkage, reliable sealing and long-term durability, effectively solving pain points such as system backflow overflow, medium pollution, hydraulic imbalance, etc. It is to ensure the safety of fluid circulation systems. The core protective components for stable operation.
core design
Card sleeve+angle integrated design, suitable for special scenarios
Adopting an integrated design of card sleeve connection and corner structure, it balances convenient installation and space adaptability, perfectly solving the problems of traditional flange and threaded valve installation being cumbersome, occupying a large space, and poor pipeline corner adaptability. The angular structure adopts a 90 ° right angle flow channel design, with inlet and outlet vertically distributed. The flow channel adopts fluid dynamics optimization design, and the corners adopt smooth rounded transitions with minimal resistance, which does not affect the normal circulation efficiency of the system. It can be directly adapted to pipeline corner installation without the need for additional bends, greatly saving installation space. It is especially suitable for installation scenarios with small spaces such as boiler return end, radiator return end, and pipeline corners. The card sleeve connection design does not require welding or complex tools. The card sleeve head is precisely attached to the valve body, and is equipped with a special sealing structure. When installing, simply insert the pipeline into the card sleeve and tighten the nut to complete the fixation. The connection is firm, the seal is tight, and the disassembly is convenient. During later maintenance, the pipeline and valve can be quickly separated, greatly improving installation and maintenance efficiency. At the same time, it has good fire and explosion prevention characteristics and is suitable for safety requirements in various scenarios such as power plants and chemical industries.
