Working principle of forged steel gate valve:

Forged steel valves are suitable for medium and high temperature, medium and high pressure valves with nominal pressure of 1.6, 2.5, 4.0, 6.4, 10.0, 16.0MPa and nominal diameter of 10~50mm. The applicable medium is water, nitrogen and hydrogen mixed urea and methylamine liquid, etc. The stem and stem nut are driven by trapezoidal thread, and the thread conforms to the requirements of GB/T5796. The head of the valve stem is designed with a conical upper sealing surface. When the moisturizing door is fully opened, the upper sealing seat of the valve cover fits tightly without external leakage. The valve body, valve cover and other pressure-bearing parts are forged as a whole (tire model forging), and the valve body flange can also be welded. The connection between the valve body and the valve seat includes flange connection and welding. The surfacing alloy layer on the valve body or the stainless steel valve is directly processed on the valve body, and the thickness of the surfacing layer is greater than or equal to 2mm. The opponent's forged steel gate valve with a nominal pressure of 16.0 MPa adopts a pressure self-tightening sealing structure, and the stuffing box and gate are all forged as a whole to ensure the compressive strength.

Forged steel gate valve product features:

(1) The flow resistance is small. The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small.

(2) It is more labor-saving when opening and closing. Compared with the globe valve, because whether it is open or closed, the direction of movement of the gate is perpendicular to the flow direction of the medium.

(3) The height is large and the opening and closing time is long. The opening and closing stroke of the gate is large, and the lowering is carried out by the screw.

(4) The medium can flow in any direction on both sides, which is easy to install. The gate valve channel is symmetrical on both sides.

(5) The structural length (the distance between the two connecting end faces of the shell) is small.

(6) The sealing surface is easy to wear and affect the use. When opening and closing, the two sealing surfaces of the gate plate and the valve seat rub against each other and slide against each other. Under the action of the medium pressure, it is easy to cause abrasion and wear, which affects the sealing performance and shortens the use.

(7) The shape is simple, the structure length is short, and the application is wide.
