AI Technical Summary
The existing water supply pressure reducing valve lacks an anti-accidental contact structure, which may lead to pressure deviation due to accidental contact during the adjustment process.
The water supply pressure reducing valve is designed to prevent accidental operation by using anti-accidental contact components and protective components. It employs mechanical locking structures such as sliding rods, limit blocks, and springs to prevent accidental contact, and combines protective sleeves and baffles to prevent foreign objects from entering, thus achieving physical locking and precise adjustment.
It effectively prevents pressure deviation caused by accidental touch, ensuring adjustment accuracy and stability, while improving the protection and durability of the equipment.
