Inclined surface ball valve, ball valve

The wedge-shaped ball valves Q16F and Q66F are designed as double-wedge type. Under the action of the spring, they can automatically adjust the sealing between the valve seat and the spherical body of the valve body, ensuring good sealing performance even under medium and low pressure conditions. The sealing at the contact area between the valve stem and the valve cover is achieved by pressing the flat surface of the packing sheet against the convex shoulder surface of the valve stem and the valve cover, which reduces the opening torque. The valve is of an integral top-mounted type, and there is no need to remove the valve from the pipeline. It can be repaired or replaced by simply removing the valve cover. This makes maintenance more convenient.

The structural features of the inclined-plane ball valve: 

1. The unique structural seal is more reliable. The inclined-plane ball valve is also known as the "wedge-type ball valve", and it adopts a new overall assembly structure. The two valve seat sealing surfaces are designed as two inclined planes, and there is a spring on the upper part of the ball. Under the action of the spring force, the valve seat sealing surfaces closely adhere to the ball, forming a reliable seal. 

2. The valve stem shoulder structure not only prevents the valve stem from coming off but also ensures the sealing performance at the top. The lower end of the valve stem has a shoulder, which can prevent the valve stem from coming off when the pressure inside the valve body abnormally increases. Under the action of the spring and the medium force, the valve stem shoulder presses the gasket, forming an upper sealing effect. 

3. The advanced fireproof and anti-static structure features a fireproof metal ring placed between the sphere and the valve seat. In the event of an accidental fire where the valve seat is damaged, the metal ring presses against the sphere, providing a sealing function. This ensures the safety of the system and prevents major accidents. The pre-tightening spring at the top of the sphere can conduct the static electricity generated by the friction between the sphere and the valve seat through a wire to the underground. This prevents sparks caused by static electricity from igniting flammable and explosive media, thus guaranteeing the safety of the system. 

4. The opening and closing forces of the valve are small, making installation and maintenance convenient. The sealing of the valve stem packing chamber adopts the combination of a flat packing surface and the protruding shoulder of the valve stem. 

The sealing of the valve cover plane is achieved by the preload force of the spring and the compressive force of the upper cover. This reduces the opening and closing forces of the valve. The valve adopts an integral top-mounted structure. By simply removing the upper valve cover, all the parts inside the valve body can be taken out. This facilitates the maintenance and replacement of the valve.

The inclined gate valve, especially the top-mounted inclined gate valve, due to its unique structure and performance, has extensive applications in multiple industrial fields, and its application prospects are very promising. The following are the main application areas and future development trends of the inclined gate valve: 

Petroleum and Natural Gas Industry: The mounted inclined surface ball valve is a core equipment in petroleum and natural gas transmission pipelines and extraction, refining facilities. In long-distance transmission pipelines, it is responsible for precisely distributing and changing the flow direction of the medium, ensuring the stable transportation of oil and gas; in the complex process flow of refineries, its high-pressure resistance and corrosion resistance can cope with the harsh working conditions of high temperature, high pressure and corrosive media, guaranteeing the safe and continuous operation of production. 

Chemical Industry: Chemical production involves a large amount of corrosive, flammable, and explosive media, which requires high standards for valve sealing and corrosion resistance. The top-mounted inclined surface ball valve adopts a special sealing structure, such as a double-sided double-layer sealing design, with soft seals applied first and hard seals added later, effectively preventing medium leakage. Key components are made of corrosion-resistant materials like stainless steel and nickel-based alloys, which can operate stably for a long time at critical positions such as the inlet and outlet of reaction vessels and pipeline systems, meeting the strict requirements for valve reliability in chemical production. 

Power Industry: In the renovation of traditional thermal power units and in new energy projects such as nuclear power, the mounted inclined surface ball valve plays a crucial role in fluid control. Its low operating torque design can reduce the load on the actuator and enhance operational convenience; its high-temperature and high-pressure resistance properties enable it to be used in steam pipelines, cooling water systems, and other scenarios, ensuring the safe and efficient operation of power equipment. 

Metallurgy and Water Supply Industry: In the metallurgy industry, the transportation of molten metals at high temperatures and the water supply network system require strict requirements for the wear resistance and sealing performance of valves. The inclined surface structure of the mounted inclined surface ball valve can reduce the impact of fluid on the ball, thereby extending the service life; its excellent sealing performance can prevent the leakage of media, avoiding waste of resources and environmental pollution, and meeting the comprehensive performance requirements of valves for the metallurgy and water supply industries.
