Introduction of DS series water seal gate valve

First, the structural characteristics and uses of DS series water seal gate valve

水封闸阀 本产品的阀盖填料室具有水密封结构,当接口通入压力为0.6-1MPa的水时,可使系统与大气隔离,保证系统具有良好的气密性。 1. Water-sealed gate valve The valve cover packing chamber of this product has a water-tight structure. When the pressure of water at the interface is 0.6-1MPa, the system can be isolated from the atmosphere to ensure the system has good air tightness.
2. DS / Z series adopts double gate to elastic seal, flexible opening and closing, fast and reliable sealing.
3. The product structure is simple, compact and reasonable, convenient for maintenance and service life.
4. For opening and closing devices on the pipeline, it must be in the fully open or fully closed state, and it should not be used to adjust the flow.
不锈钢阀门 连接方式有法兰和焊接两种,驱动方式为手动和电动。 5. There are two types of stainless steel valve connection: flange and welding. The driving method is manual and electric.
6. DS series water-sealed valve is suitable for opening and closing devices on pipelines with nominal pressure ≤10.0MPa, working temperature ≤425 C, and working medium of water, steam, oil and non-corrosive gas, especially for vacuum condensation of steam turbines in power plants system.

Second, the main performance specifications of DS series water seal gate valve

test pressure Nominal pressure PN (MPa)
1.0 1.6 2.5 4.0 6.4 10.0
Shell strength test 1.5 2.4 3.8 6.0 9.6 15.0
Seal test 1.1 1.8 2.8 4.4 7.0 11.0
Upper seal test 1.1 1.8 2.8 4.4 7.0 11.0
Hermetic seal test 0.5-0.7

Third, the use of DS series water seal gate valve

product type proper temperature Applicable medium ℃
Carbon steel type C ≤425 ℃ Water, steam, oil, non-corrosive gas
Alloy steel type I ≤540 ℃ Water, steam, oil, non-corrosive gas
