Oil / Gas Pipeline Valve SS316 SS304 Check Stainless Steel Valve

Standard Check Valve For Oil Pipeline Valve 

Pipeline Check Valve Introduction

A pipeline check valve, also known as an inline check valve or line check valve, is a type of valve that is designed to allow fluid to flow in one direction only in a pipeline. It consists of a valve body with an internal mechanism that automatically opens and closes a valve disc or other closure element in response to the direction of fluid flow.

The main purpose of a pipeline check valve is to prevent backflow of fluid in a pipeline, which can cause damage to equipment, contamination of the fluid, or other safety hazards. When the fluid flows in the forward direction, the valve disc is pushed open by the fluid pressure, allowing the fluid to pass through the valve. When the fluid flow stops or reverses, the valve disc or other closure element is automatically closed by gravity, spring force, or other means, preventing the fluid from flowing back through the valve.

Application

1. Backflow prevention: A pipeline check valve is designed to prevent backflow of fluid in a pipeline, which can cause damage to equipment, contamination of the fluid, or other safety hazards.

2. Pressure relief: A pipeline check valve can also relieve pressure in a pipeline by allowing fluid to flow in the reverse direction when the pressure exceeds a certain limit, which helps to protect the pipeline and equipment from damage.

3. Flow control: A pipeline check valve can be used to control the flow rate of fluid in a pipeline by adjusting the size of the valve opening, which can help to optimize the efficiency of the system and reduce energy consumption.

4. System protection: A pipeline check valve can protect the system from damage or failure caused by backflow, which can be costly and time-consuming to repair.

Working Principle

The medium flows into the pipeline in the specified direction. When the flow pressure exceeds the opening pressure of the check valve, the valve disc is lifted by the fluid pressure, thereby connecting the pipeline medium flow. Conversely, when the pipeline medium flows back, the valve disc is pressed against the check valve body under the driving force of fluid pressure, and the valve is closed, thereby cutting off the pipeline medium flow. Moreover, the greater the pressure of the backflow medium, the tighter the valve disc is closed, resulting in a better sealing effect, completely eliminating the possibility of medium backflow.
