Stainless steel globe valve

Stainless steel globe valve is a kind of globe valve. The material requirements for valve body are relatively high. Generally, there are several materials such as 301.304.316, which are widely used in chemical, ship, medicine, food machinery and other industries. Stainless steel globe valves are divided into manual stainless steel globe valves, pneumatic stainless steel globe valves, and electric stainless steel globe valves.

  The holding point of the stop valve:

 

  (1) The structure is simpler than the gate valve, and it is convenient to manufacture and maintain.

 

  (2) The sealing surface is not easy to be worn and scratched, and the sealing property is good. There is no relative sliding between the valve flap and the sealing surface of the valve body when opening and closing, so the wear and the scratch are not serious, the sealing performance is good, and the service life is long.

 

  (3) When opening and closing, the valve flap stroke is small, so the height of the shut-off valve is smaller than that of the gate valve, but the structural length is longer than the gate valve.

 

  (4) The opening and closing torque is large, the opening and closing is more laborious, and the opening and closing time is the principal.

 

  (5) The fluid resistance is large, because the medium passage in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.

 

  (6) Direction of medium flow When the nominal pressure PN ≤ 16MPa, the downstream flow is generally adopted, and the medium flows upward from the lower side of the valve flap; when the nominal pressure PN ≥ 20MPa, the counterflow is generally used, and the medium flows downward from above the valve flap. To increase the sealability. When in use, the shut-off valve medium can only flow in one direction and cannot change the flow direction.

 

  (7) The valve flap is often eroded when fully open.
