Product Name: RV-25-07-B-SS inlet check valve
Material: Stainless steel
Product introductionRV-25-07-B-SS check valve model is RV-25-07-B-SS, nominal diameter is DN6-DN50 widely used in water, petroleum, Natural gas pipeline system and oil field system.
First, the basic product introduction:
广泛应用于压力3000Psi-6000Psi ，温度-20-+450 ℃的水、石油、天然气管道系统及油田系统。 Imported welded high pressure check valve model is RV-25-07-B-SS, nominal diameter is DN6-DN50, widely used in water, petroleum, natural gas pipeline system and oil field with pressure 3000Psi-6000Psi , temperature -20- + 450 ℃ system. It consists of a valve body, a valve disc, a spring and a central shaft. Except the valve body is made of carbon steel, the other materials are stainless steel. It is a valve that automatically opens and closes the valve flap by relying on the flow of the medium itself. It is also called a check valve, check valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve, and its main function is to prevent the medium from flowing backward, to prevent the pump and the drive motor from reversing, and to release the medium from the container. The valve is normally closed. The pressure of the medium at the inlet end of the pipeline acts to overcome the resistance of the spring to open the valve. When the medium pressure at the inlet end is lower than the outlet section, the spring closes the valve to prevent the medium from flowing backward and play a check function.
Second, the main parameters of imported welded high pressure check valve:
1. Product brand: Jiangsu Zhongli
2. Product model: RV-25-07-B-SS
3. Nominal caliber: DN6-DN50
4. Pressure: 3000Psi-6000Psi
5. Material: stainless steel
Structural features of imported welded high pressure check valve:
1. Imported welded high pressure check valve can be installed straight or vertical (easy installation).
2. The upper and lower valve bodies are connected by threads. Streamlined shape, beautiful shape.
3. Manufacturing and acceptance conditions are strictly in accordance with standards.
的管道，密封性能可靠，经久耐用。 4. The imported welded high-pressure check valve is suitable for pipelines with a pressure of 10-40MPa , and its sealing performance is reliable and durable.
5, the valve disc, valve seat sealing surface surfacing Stellite alloy, high hardness and durable, never wear.
6. The internal structure of the imported welded high-pressure check valve is spring loaded straight through. The valve has no noise during opening and closing, the fluid movement direction changes little, the pressure loss is small, water hammer is reduced, and economic energy is saved.
Advantages of imported welded high pressure check valve:
1. Exquisite selection of materials, meeting relevant standards, high quality of materials.
2. The product is produced according to the requirements of the American Standard.
3. Various piping flange standards and flange seal types can be used to meet various engineering needs and user requirements.
4. There is a complete range of valve body materials. Gaskets can be reasonably selected according to actual working conditions or user requirements, and can be applied to various pressure, temperature and medium working conditions.
）钴基硬质合金堆焊面成，耐磨、耐高温。 5. The sealing pairing is advanced and reasonable. The sealing surfaces of the valve disc and valve seat are made of iron-based alloy or Stellite cobalt-based hard alloy surfacing surface, which is wear-resistant and high-temperature resistant.
V. Structural features of imported welded high-pressure check valves:
1. The structure length is short, and the structure length is only 1/4 ~ 1/8 of the traditional flange check valve
2. Small size and light weight, its weight is only 1/4 ~ 1/20 of traditional flange check valve
3. The valve flap closes quickly and the water hammer pressure is small
4. Both horizontal and vertical pipes can be used, easy to install
5.The flow channel is unobstructed and the fluid resistance is small
6, sensitive action, good sealing performance
7.Short stroke of valve and small closing impact force
8, the overall structure is simple and compact, beautiful appearance
9.Long service life and reliable performance
Installation precautions of imported welded high pressure check valve:
1. Do not make the check valve bear the weight in the piping system. The large check valve should be independently supported so that it is not affected by the pressure generated by the piping system.
2. When installing, pay attention to the direction of the medium flow should be consistent with the direction of the arrow marked on the valve body.
3. Lifting vertical flap check valve should be installed on vertical pipeline.
4. The lifting horizontal flap check valve should be installed on the horizontal pipeline.
