What are the causes of Check Valve vibration?
Check Valve is a key component in fluid machinery (including electric machinery, chemical machinery, fluid power machinery, etc.) to control the flow capacity. Its performance and safety are closely related to the working performance, efficiency and reliability of the entire device. In industrial production processes such as oil refining, petrochemicals and power generation, vibration, noise and valve stem rotation of Check Valve often occur. Accidents such as valve stem breakage due to vibration also occur from time to time.
Basic knowledge of Check Valve
The so-called Check Valve is a valve that automatically opens and closes according to the flow of the medium itself. It is a valve used to prevent the reverse flow of the medium. It is also called a Check Valve, one-way valve, reverse flow valve, and back pressure valve. The stop valve is an automatic Universal Valve. Its main function is to prevent the reverse flow of the medium, prevent the pump and drive motor from reversing, and prevent the drainage of the container medium. Stop valves can also be used to supply auxiliary systems where the pressure in the pipeline rises above the sys
Working principle and basic knowledge of Butterfly Valve
Butterfly Valve generally adopt a three-eccentric multi-layer metal hard-sealing structure and are frequently used in industrial pipelines such as metallurgy, electric power, petrochemical industry, water supply and drainage, and municipal construction with medium temperatures ≤425°C to regulate flow and load-break fluids. The valve adopts a triple eccentric structure. The Universal Valve and the disc sealing surface are made of different hardness and stainless steel. It has good corrosion resistance and long service life. The commonly used connection methods of Butterfly Valve are di
Throttle Valve structural characteristics and working principle
The Throttle Valve is a safety protection valve. Its opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises and exceeds the specified value, it automatically opens and discharges the medium out of the system. Prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value. Throttle Valve are widely used in natural gas, petroleum gas and chemical pressure vessel equipment and industrial pipelines. They have the outstanding advantages of fire protection, expl
There is an adjusting nut at the top of the Universal Valve, which can be adjusted. But it is best not to move around, because individuals do not have the qualifications. If an accident occurs, the damage caused will be subject to serious criminal liability. It needs to be verified by an institution with relevant qualifications. Qualifications are different in each place, but The local special supervision institute must be qualified.
Briefly describe the key points of Globe Valve pipeline layout design
1. The Globe Valve should be installed upright and close to the protected equipment or pipeline. If it cannot be arranged close, the total pressure drop in the pipeline from the protected equipment or pipeline to the inlet of the Globe Valve should not exceed 3% of the fixed pressure value of the Globe Valve. 2. The Globe Valve should be equipped with a maintenance platform. When arranging heavy Globe Valve,
Precautions for maintaining and maintaining Relief Valve
The Relief Valve is an auxiliary device that automatically removes gas in the pipeline or keeps the pressure in the system constant. When the medium pressure in equipment or pipelines exceeds the specified value (i.e. working pressure), it is a safety accessory product that prevents damage to equipment and pipelines by discharging gas with a certain pressure into the system. It is usually installed at the highest point of the system to prevent excessive static pressure from being generated; when the equipment fails, the pressure relief can be automatically opened to prevent further expan
Do you know what a Relief Valve is?
The Relief Valve is an intelligent general-purpose valve, which has automatic control, self-inspection, intelligent alarm and protection functions, which can effectively protect the safety of the system and prevent the system from explosion, fire and other dangerous situations. The Relief Valve is an intelligent Relief Valve, its main function is to set a safety threshold in the system, when the system pressure exceeds the
