The throttle valve is a kind of pump valve fitting. According to its different channel direction, it mainly includes several different structures: straight-through throttle valve, DC throttle valve and angle throttle valve. The throttle valve mainly controls the fluid flow by changing the throttling section or the throttling length, and is widely applicable to the medium cutting or regulating flow in the conveying pipelines of food, medicine, petroleum, chemical, natural gas, steel, environmental protection, papermaking and the like.
In practical applications, the pump valve fitting throttle valve mainly rotates the hand wheel first, and the opening and closing of the valve stem connected to the valve stem is achieved by the advancement and retreat of the thread of the hand wheel and the valve stem. effect.
In the structural design, according to the user's requirements, the spring loaded packing impact system of the pump valve fitting throttle valve uses a spring loaded packing impact system to improve the durability and reliability of the packing seal. The throttle valve stem is made by integral forging process. The valve stem is quenched and tempered and surface nitrided. It has good corrosion resistance, scratch resistance and wear resistance. The minimum diameter, stem and gate are determined according to standard requirements. The plates are connected by a T-shaped structure.http://www.pump-casting.com/
