I. Overview of Z41Y forged steel flanged gate valve :
Forged steel gate valve has three types of bonnet design. The first is a bolt-type bonnet. The valve designed according to this design has a valve body and a bonnet connected by bolts and nuts, and a wound gasket (made of 316 flexible graphite). Sealing. Metal rings can also be used when customers have special requirements. The second design form is a welded bonnet. According to this design, the valve body and the bonnet are threaded and fully welded. The customer has special Welding can also be used when required. The third type is a self-sealing bonnet. The valve designed according to this design has a threaded connection between the valve body and the bonnet, and an internal pressure self-tight ring seal.
Structural features of Z41Y forged steel flanged gate valve:
1. Forged steel valves are suitable for medium and high temperature, medium and high pressure valves with a nominal pressure of PN2.5, 4.0, 10.0, 14.0, 25.0Mpa and a nominal diameter of DN10-50mm. The applicable medium is water, nitrogen-hydrogen mixed gas, urea and methylamine solution.
2. Stem and stem nut are trapezoidal thread transmission, and the thread complies with the regulations of GB5796. The head of the valve stem is designed with a tapered upper sealing surface. When the valve is fully opened, it closely matches the upper sealing seat of the valve cover, and there is no external leakage.
3. The valve body, valve cover and other pressure-bearing parts are forged integrally (tire model forging), and the valve body flange can also be welded. The valve connection forms include flange connection, socket welding connection and internal thread connection.
4. The connection between the valve seat and the valve body is made by threaded connection, welding, welding on the valve body with alloy layer or stainless steel valve directly on the valve body. The thickness of the surfacing layer is 2 mm or more.
5. For forged steel valves with a nominal pressure greater than 15.0Mpa, a pressure self-tight seal structure is adopted, and the stuffing box and the gate are all forged to ensure compressive strength.
6. Forged steel valves are suitable for medium and high temperature, medium and high pressure valves with a nominal pressure of PN2.5, 4.0, 10.0, 14.0, 25.0Mpa and a nominal diameter of DN10-50mm. The applicable medium is water, nitrogen-hydrogen mixed gas, urea and methylamine solution.
7. The valve stem and the stem nut are trapezoidal thread transmission, and the thread complies with the regulations of GB5796. The head of the valve stem is designed with a tapered upper sealing surface. When the valve is fully opened, it closely matches the upper sealing seat of the valve cover, and there is no external leakage.
8. The valve body, valve cover and other pressure-bearing parts are forged integrally (tire model forging), and the valve body flange can also be welded. The valve connection forms include flange connection, socket welding connection and internal thread connection.
9. The connection between the valve seat and the valve body is made by threaded connection, welding, welding on the valve body with an alloy layer or stainless steel valve directly on the valve body. The thickness of the surfacing layer is 2 mm or more.
10. For forged steel valves with a nominal pressure greater than 15.0Mpa, a pressure self-tight seal structure is used, and the stuffing box and the gate are integrally forged to ensure compressive strength.
