Lift Check Valve

A check valve is a valve used in a pipeline system. Its main function is to prevent the backflow of the medium. It acts as a one-way valve in the pipeline, automatically or through external force to prevent the fluid from flowing back from the outlet of the pipeline to the inlet, ensuring that the fluid flows in the correct direction to avoid equipment damage, pollution or system failure.

※ Basic Structure

Valve body: The outer shell of the check valve, which serves to accommodate and protect the various internal parts.
Valve seat: The part of the valve body that contacts the valve disc, used to form a seal to prevent medium leakage.
Valve disc: Usually the core component of the check valve, responsible for opening or closing the valve according to the pressure changes of the fluid. The valve disc can be in various forms such as disc, ball, butterfly, etc.
Spring (optional): Used to help the valve disc close or ensure that the valve disc automatically closes when there is no fluid flow.
Sealing ring: Used to enhance the sealing between the valve seat and the valve disc to prevent leakage.

※ Product Application
Water treatment and water supply system
Prevent water backflow, ensure water quality, and avoid sewage or pollutants in the pipeline.
Oil and gas industry
Prevent oil and gas backflow, protect pipeline systems and pumps and other equipment.
HVAC system
Ensure that air or cooling water flows in the pipeline in a predetermined direction to avoid gas backflow or backflow of heat exchange media.
Fire protection system
In fire protection pipelines, check valves can effectively prevent water from flowing back into the pipeline network to ensure the effectiveness of the fire extinguishing system.
Chemical and pharmaceutical industries
Prevent media backflow, avoid cross-contamination between different chemicals, and ensure production safety and product quality.

※ Product Advantage
Prevent media backflow
The most significant advantage is that it can automatically prevent fluid from flowing back in the pipeline, protecting equipment from damage and avoiding system failure.
Automation
Most check valves do not require manual operation or external power, and automatically control opening and closing through fluid pressure, reducing manual maintenance.
Save energy and improve efficiency
By preventing backflow, energy waste is avoided, which plays an important role especially in water pumps and other equipment.
Enhance system stability
Check valves can ensure that the medium in the system flows in the correct direction, avoid reverse pressure in the system, and ensure the safe operation of the equipment.
Simple structure and easy maintenance
Check valves usually have a simple structure, long service life, and require little maintenance.
Adaptable
According to different requirements such as fluid medium, pipe diameter, pressure, etc., different types of check valves can be selected, such as lift type, ball type, butterfly type, etc., which have strong adaptability.

※ FAQ

What are the installation requirements for control valves?
The valve should be installed at the appropriate position of the pipeline to ensure that the flow direction is consistent with the direction indicated by the valve body; secondly, check whether the valve and its accessories are intact before installation to ensure that there is no damage; during installation, ensure that the pipeline connection is stable to avoid stress concentration and prevent damage to the valve; in addition, sufficient space should be provided for the valve to facilitate adjustment, inspection and maintenance; finally, the valve should be protected from excessive vibration or temperature, especially under high pressure and high temperature environments.

What are the common applications of temperature and pressure reducers?
Temperature and pressure reducers are widely used in many fields. They are mainly used in steam systems to reduce high-pressure steam to appropriate pressure to ensure safe operation of equipment. They are commonly used in power, fertilizer, food processing and other industries. They are also used in oil and gas pipelines, chemical production, pharmaceutical plants, etc. to ensure stable pipeline pressure and avoid system overpressure or excessive temperature. In addition, reducers are also used in HVAC, metallurgy and other industries to adjust the temperature and pressure of the fluid in the system to ensure the smooth progress of the process.

How to maintain medium and high pressure valves?
When maintaining medium and high pressure valves, first check the wear of key components such as valve body, valve seat, sealing ring and valve stem regularly. Clean the valve to prevent impurities from blocking and affecting operation. Check the operating performance of the valve to ensure flexible opening and closing without sticking. Check the sealing to prevent leakage and replace the seals if necessary. For valves that operate at high pressure for a long time, it is recommended to perform functional tests regularly to ensure their reliability under high pressure environment. In addition, check the connection parts of the valve to avoid looseness or leakage caused by vibration or corrosion.
