stainless steel ball valve introduction
1.stainless steel ball valve overview:
Stainless steel ball valve is a new product of ball valve series. The valve can not only be reliably cut off under positive pressure, but also can be reliably sealed when the reverse pressure or reverse pressure is much greater than the forward pressure.
The stainless steel ball valve adopts the structure and principle of hemispherical valve for sealing and butterfly structure for its shape, so it has the characteristics of small volume and light weight; it also has the performance of two-way hard seal, small sealing friction, durability, and light opening and closing. Therefore, the cost performance ratio is far higher than that of the hemispherical valve. The successful development and application of stainless steel ball valve is a major technical innovation in valve industry.
2. stainless steel ball valve working principle:
The main types of stainless steel ball valve: the main types of this valve are: worm gear, electric, pneumatic, hydraulic, among which pneumatic valve and hydraulic valve are suitable for occasions with pressure gas source and pressure liquid source.
Working principle of stainless steel ball valve: the main function of the two-way flow valve is that it can not only seal well under positive pressure, but also seal well when reverse pressure or reverse pressure is greater than positive pressure. When the positive pressure acts, the medium pressure pushes the valve plate to move forward and the valve stem deforms. The sealing surface of the valve plate is close to the sealing surface of the valve seat to transmit pressure, which pushes the valve seat to the valve body step to make it well sealed. When the reverse pressure acts, the medium pressure pushes the valve plate to move backward, the valve stem deforms, and the medium pressure pushes the valve seat to move backward at the same time. The sealing surface of the valve seat is close to the sealing surface of the valve plate to transmit pressure to make it seal well.
