2. Product Overview
"Boang Brand" exhaust relief ball valve is a thermoplastic plastic engineering material. It has certain strength, stiffness, toughness, impact resistance, corrosion resistance and wear resistance. By controlling the polymerization process and adding a certain amount of comonomer during polymerization, the properties of polyethylene materials can be adjusted or improved. The integral valve body has basically no external leakage. The various components that make up the valve shell are connected by hot melt or electrofusion. Therefore, the entire valve shell has high connection strength and good sealing performance. The ball valve and the pipeline are directly welded to form a non-detachable structure. Overall, no leaks. The gas ball valve does not require anti-corrosion. All the functional parts of the valve are made of polymer organic materials, which have very good soil corrosion resistance, no corrosion, and do not require anti-corrosion. Maintenance-free and repair-free, it can be directly buried using specially designed connecting sleeves and matching valve barrels and manhole cover structures. Standard valves do not need to build valve wells and can be directly buried, while relief valves only need to build shallow wells.

4. Product performance
For the sealing structure of the valve, consider the characteristics of plastics, design a reasonable upper and lower support structure of the valve core, appropriate sealing materials, between the stem and the valve body More than one rubber ring is used between them, so the sealing performance is excellent
. The molding process of the valve core and valve body meets the requirements of the valve structure, strength and stiffness
. Strengthening the sealing of the ball (rubber) , widen the contact surface between the ball and the seal, and make it full of elasticity during design, so the oversized sealing surface design is enough to ensure the sealing performance requirements
, forming mold manufacturing and debugging
, design the ball aperture to the full diameter, minimizing pressure loss
, designed to be buried underground, minimizing the spacing of the release, and small valve wells can be used
, due to the characteristics of polyethylene, corrosion resistance, flexibility, chemical resistance , Poor cold resistance
The bottom of the valve body is designed to be flat, making it easy to install it flat during construction.
