Slab Gate Valve for Oil Field

Price: The price is changing because of material cost and exchange rate. Please give me your contact information, I will update the newest price to you.

1. It has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth channel, low resistance, easy installation and easy disassembly.

2. When the valve is fully opened, the flow resistance coefficient is very small, and the valve will eliminate the function of the valve disc and the dirt on the sealing surface every time the valve is opened and closed.

3. The packing is made of flexible graphite ring and graphite packing, reliable sealing, light and flexible operation.

4. It is widely used in oil and water steam pipelines such as petrochemical industry and thermal power plants to connect or cut off the intermediate quality of pipelines. The sealing surface of the opening and closing device has compact structure and reasonable design.

5. Suitable for natural gas, petroleum, chemical, gas pipelines and other transmission lines, vent systems and steam storage devices, used as opening and closing equipment. Long haul pipeline for natural gas extraction and purification.

Q: What are the three main factors to consider when selecting an implementing agency?

A: The output of the actuator should be greater than the load of the valve and reasonably matched. When checking the standard combination, it is necessary to consider whether the allowable pressure difference specified in the valve type meets the process requirements. When the pressure difference is large, the unbalance force of the valve core should be calculated. It is necessary to consider whether the response speed of the actuator meets the process operation requirements, especially the electric actuator.

Q: The selection principle of valves in the petroleum and chemical industry?

A: In the face of so many door classification and such a complex variety of working conditions, to choose the suitable lake door products for pipeline system installation, we should first understand the characteristics of the valve; Secondly, the steps and basis for selecting the valve should be mastered; In addition, the principle of selecting valves for the petroleum and chemical industries should be followed.

The principle of choosing the valve in the petroleum and chemical industry: the flow channel is a straight-through valve, whose tears are small, and the reading door is usually selected as a closing and opening medium; Easy to adjust the flow of the valve as a control meteor; Plug valve and ball palm are more suitable for reversing shunt; Sliding of the closure along the sealing surface valves with wiping action are suitable for media with suspended particles.

1. Valves for closing and opening media

The flow channel is a straight-through valve, whose flow resistance is small, and the valve is usually selected as a cut-off and opening medium. Downward closed door (globe valve, plunger valve) because of its flow path twists and turns, the flow resistance is higher than other threshold, so it is less used. In cases where high flow resistance is allowed, closed valves can be selected.

2. Control flow valve

Usually choose a valve that is easy to adjust the meteor as a control meteor. Downward closing valves (such as globe valves) are suitable for this purpose because the size of the seat is proportional to the stroke of the closing member. Rotary valve (plug valve, butterfly valve, ball adjustment) and drop body valve (clamp valve, diaphragm valve) can also be used for throttling control, but usually only in a limited range of door calibers. Gate valve is a disc-shaped gate to the circular 裀 seat mouth to cross cutting movement, it can only be close to the closed position, in order to better control the flow, so it is usually not used for flow control.

3. Reversing shunt valve

The valve may have three or more channels, depending on the need for reversing shunt. Plug valves and ball valves are more suitable for this purpose, so most valves used for reversing shunt use one of these types of valves. However, in some cases, other types of valves, as long as two or more valves are properly connected to each other, can also be used for reversing shunt.

4. With suspended particles medium valve

When there is a suspended jaw particle in the medium, it is suitable for using the sliding door with wiping action along the sealing surface of the closing part. If the closure is vertical in its back and forth motion against the seat, it may clamp the glume, so this type of door is only suitable for basically clean media unless the sealing surface material can allow embedded particles. Ball valves, plug valves and butterfly valves have a wiping effect on the sealing surface during opening and closing, so they are suitable for use in media with floating particles.
