F304 forged steel ball valve for pressure vessels
F304 forged steel ball valve for pressure vessels
The classification and characteristics of forged steel ball valves can be divided into two categories: low pressure and high pressure. High pressure forged steel ball valves are designed according to user needs to meet application requirements in sulfurized environments. Their design, material selection, manufacturing, testing, surface treatment, and painting are strictly in accordance with the American Society of Corrosion EngineersCompared with other types of valves, ball valves have the following advantages:
a、 The fluid resistance is small, and ball valves have the lowest fluid resistance among all valve types. Even for reduced diameter ball valves, their fluid resistance is quite small.
The switch is fast and convenient. As long as the valve stem rotates 90 °, the ball valve completes the fully open or fully closed action, making it easy to achieve rapid opening and closing.
c、 Good sealing performance. The sealing ring of the ball valve seat is generally made of elastic materials such as polytetrafluoroethylene, which is easy to seal, and the sealing force of the ball valve increases with the increase of medium pressure.
d、 The valve stem seal is reliable. When the ball valve is opened and closed, the valve stem only rotates, so the packing seal of the valve stem is not easily damaged, and the sealing force of the valve stem reverse seal increases with the increase of medium pressure.
e、 The opening and closing of the ball valve can only rotate 90 degrees, making it easy to achieve automation and remote control. The ball valve can be equipped with pneumatic, electric, hydraulic, pneumatic hydraulic or electro-hydraulic linkage devices.
f、 The ball valve channel is flat and smooth, not easy to deposit media, and can be used for pipeline ball passing.
Worm gear ball valve, forged material can ensure sufficient hardness and strength without inherent defects under rated operating pressure. The sufficient wall thickness determines the body and adapts to different high-strength bolt valve systems for easy maintenance and the valve internals that are capable of bearing pressure pipeline valves are carefully designed and selected for various reliable working conditions.
a: Fire safety structure: When the ear shaft ball valve is in normal use, it is covered with a valve seat and spherical surface, a valve seat holder O-ring, and a stamped body. This is a soft seal and reliable sealing. When the valve seat and O-ring are damaged, the valve seat holder and body will be covered with expanded graphite for the purpose of fire safety.
b: Anti static equipment: In order to prevent the generation of static electricity between the friction ball, rod, and polytetrafluoroethylene, which may ignite flammable materials and cause accidents, static electricity between the valve stem and ball, valve stem and body is guaranteed for ground and system safety.
c. Body sealing structure with free leakage: Smooth operation, double capped gaskets and O-rings on the valve body and valve cap at the opening and closing positions of the valve. Based on this, factors such as fire, high temperature, shock absorption, and uneven opening or closing torque will not cause external leakage.
d. Operating low torque: Self lubricating bearings are installed in frictional * * *, resulting in wear-resistant, flexible operation and low torque.
e. Double blocking leakage: When the ball is fully open or closed, the transmitter material body can release the drainage and emptying device at the center of the chamber. In addition, the central pressure valve chamber can be released to the seat where low pressure has ended its rescue.
f. The design of emergency sealed composite injection holes and the installation of composite injection valves on support valves located on the valve stem/cap and body can be used to induce leakage when the sealing valve stem or seat is damaged. This compound can be used for * * * sealing concealed check valves. There are composite injection valves installed next to it to prevent the rapid connection of the fuel injection valve's composite connector injection gun due to the effect of the outflow compound.
g. Extended valve stem: Underground installation of valves, the valve stem can be extended, and corresponding composite fuel injectors and drain valves can be extended to facilitate operation.
h. Automatic body cavity, rescue: When the body pressure rises abnormally, such as unstable factors, the downstream valve seat of the ear ball valve will be subjected to normal pressure, and the abnormal pressure will be automatically released without damaging the sealed upstream seat.
