The advantages of electric gate valves are as follows:
1. Continuously absorb foreign advanced valve technology to create first-class quality products.
2. The structure of development and design is perfect, so as to make the brand beautiful and generous and practical.
3. Variety of valve body materials is complete and carefully planned by application occasions.
4. Packing and gasket selection, easy switch.
5. Excellent sealing performance. Leakage probability is close to zero.
Characteristic of electric gate valve:
1. The fluid resistance is small, and the sealing surface is eroded and eroded by the medium.
2. Opening and closing is more labor-saving.
3. The flow direction of the medium is unrestricted, without disturbance or pressure reduction.
4. Simple in shape, short in length, good in manufacturing technology and wide in application.
Main features and applications of electric gate valves:
1. Flexible graphite is usually used as filler material. PTFE or composite filler materials can be provided according to user's needs. The surface roughness of the contact between packing and packing box is 3.2mm, which can ensure that the stem and packing contact surface are closely connected, but rotate freely. The precision machined stem sealing surface roughness is 0.8mm, which can ensure the reliable sealing of the stem.
2. All the gate valves provided by our company have reverse sealing design. Usually, the carbon steel gate valve seat design adopts separate reverse sealing structure. The reverse sealing of stainless steel gate valve is directly processed or after welding. When the valve is in full open position, the sealing surface of the reverse seal is very reliable. Although there is an inverted seal in standard AP1600, this is not the basis for replacing packing under pressure.
3. It is made by integral forging process, and the minimum diameter is determined according to the standard requirements. The stem and disc are connected by T-shaped structure. The strength of the stem joint is greater than that of the T-thread part of the stem. The strength test is carried out according to API 591.
4. Carbon steel gate valve seats are usually made of forged steel. Seat sealing surface can be sprayed with cemented carbide and other materials according to customer requirements. NPS10 gate valve uses separated screw-in seat. If user needs to weld seat structure, it can also be provided; NPS12 gate valve uses welded seat structure; stainless steel gate valve seats are generally integral. Or directly process the seat after welding the cemented carbide on the seat. Stainless steel gate valves can also be separated threaded and welded seats if required by users.
5. Driving modes include manual, electric, pneumatic and gear drive. Structural types: elastic wedge single gate and rigid wedge double gate.
6. Widely used in petrochemical industry, thermal power plants and other oil products, steam pipelines for the opening and closing device to connect or cut off the medium in the pipeline.
