Products Details

Oil field special flat gate valve is a valve used to control the flow of fluid (liquid, gas or steam) in the pipeline. It is called a plate gate valve because it uses a plate or wedge to control the flow of fluid through the valve. When the valve is fully opened, the ram fully lifts out of the flow path, allowing the fluid to pass through the valve with very little resistance. When closed, the ram descends back into the flow path, creating a tight seal that prevents fluid from passing through.

Field-specific flat gate valves are typically designed for use in fully open or fully closed positions, which means they are not suitable for throttling or regulating flow. However, they offer several advantages, including:

Low pressure drop: When fully opened, flat gate valves have a very low pressure drop, which means they have little resistance to flow and do not impede the flow of fluid.
High flow capacity: Flat gate valves have a large port size and straight-through design, allowing them to handle large amounts of fluid flow.
Simple and reliable design: Flat gate valves have a simple design and few moving parts, making them reliable and easy to maintain.
Flat gate valves for oilfield applications are available in a variety of materials, including cast iron, steel, bronze and PVC, in a variety of sizes and pressure grades to suit different applications. They are commonly used in systems where the flow needs to be completely shut off, such as in fire protection systems, natural gas pipelines, and oil and gas pipelines.

In addition, the oil field special flat gate valve has the characteristics of reliable sealing performance, small opening and closing moment, sulfur resistance and wear resistance, long service life, and can clean the pipeline with hairball. Suitable for water, oil, natural gas, steam and other non-corrosive and corrosive media pipeline system as a opening and closing device, especially suitable for oil, natural gas, long-distance pipeline and other fields. Operating temperature range is -29℃ to 129℃.

Flat gate valves for oil fields can also be designed to have different end connections, such as flanged, threaded or welded connections, for easy installation and removal in piping systems.

However, flat gate valves also have some limitations. For example, they are not suitable for applications that require frequent operation, as the ram may become stuck due to sediment or debris in the pipe. In addition, flat gate valves are not recommended for systems with high speed flow, as the gate can be damaged or eroded over time.

The special flat gate valve for oilfield can be further classified into parallel sliding flat gate valve and wedge flat gate valve. Parallel sliding plate gate valves have a plate gate that moves in a direction parallel to the direction of fluid flow. This valve provides a tight seal and is commonly used in high pressure applications. Wedge plate gate valves have a wedge shaped gate that helps provide a tighter seal when the valve is closed. This valve is usually used in low pressure applications.

In summary, the oil field special flat gate valve is a valve used to control the flow of fluid in the pipeline. They offer several benefits, including low pressure drop, high flow capacity, simple and reliable design, and good sealing performance. However, they also have some limitations and are not suitable for all applications. The type of flat gate valve used depends on the specific application and the operating conditions of the system.

In addition, the invention of an oilfield pipeline flat gate valve discloses a structure including a valve body, a valve cover, a valve stem and a gate plate, which is characterized in that the corresponding valve body on both sides of the flow channel is respectively provided with an installation chamber, the installation chamber is provided with an upper, middle and lower push block that can move left and right between the left and right seat and the right seat, and an elastic part is provided between the outer side of the push block and the valve body, and the push block is provided with a driving slot. The drive groove is pierced with a lifting drive shaft, the drive shaft is matched with the drive slope, the upper push block is provided with a mounting slot, and the mounting slot is provided with a floating block that can move up and down, effectively preventing the mud medium from remaining in the lateral position between the left and right seat.

Lianggu Valve Group Co., Ltd. The new floating seal structure is used for opening, closing and regulating control media such as oil and natural gas with pressure less than 15.0MPa and temperature ranging from -29 ° C to 121 ° C. The product has a novel structural design and material selection, after appropriate and strict testing, light operation, with strong corrosion resistance, wear resistance and erosion resistance, is the ideal new equipment for the petroleum industry.
