This series of products adopt a new floating sealing structure, which is suitable for natural gas pipelines with pressure less than 10 MPa and high content of H2S gas at - 29-121 C. It is a kind of opening and closing and regulating device as control medium. The product has novel structure design, proper material selection, strict testing, convenient operation, strong anti-corrosion, wear resistance and erosion resistance, and it is a principle in the petroleum industry. Think of new equipment.
2. Application range of manual flat gate valve Z43F-16C:
Flat gate valves are suitable for natural gas, petroleum, chemical industry, environmental protection, urban pipelines, gas pipelines and other transportation pipelines, venting systems and steam storage devices, as hoisting and closing equipment.
Z43 single gate type flat gate valve with diversion hole is suitable for long distance pipeline of natural gas exploitation and purification.
3. Structural Characteristics and Working Principles
1. Floating seat, two-way opening and closing, reliable sealing, flexible opening and closing.
2. The gate is precisely guided by guide strips, and the sealing surface is sprayed with cemented carbide to resist erosion.
3. The bearing capacity of the valve body is high, and the passage is straight-through. When it is fully open, it is similar to the gate diversion orifice and straight pipe, and the flow resistance is very small. The valve stem adopts compound packing and multiple seals, which make the seal reliable and has low friction.
4. When closing the valve, turn the handwheel clockwise and move the gate down to the bottom. Due to the effect of medium pressure, the seal seat at the import end is pushed towards the gate, forming a larger specific pressure of the seal, thus forming a * channel seal. At the same time, the gate is pressed on the sealing seat at the outlet end to form a double seal.
5. Because of the double sealing, the vulnerable parts can be replaced without affecting the work of the pipeline. This is an important feature that our products take precedence over similar products at home and abroad.
6. When opening the gate, rotate the handwheel counter-clockwise, move the gate, and connect the diversion hole with the channel hole. As the gate rises, the through holes gradually increase. When the gate reaches the limit position, the diversion holes coincide with the channel holes and are fully open at this time.
Scope of application: The product can be used in petroleum, chemical and other industries.
Product conformity standard: GB/T 19672
