How much do you know about Check Valve?
The specific categories of Check Valve include: stainless steel Check Valve, plastic Check Valve, sanitary Check Valve, carbon steel Check Valve, two-way Check Valve, three-way Check Valve, and four-way Check Valve. Check Valve are used to output liquid low-temperature media such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc. They are not
Some knowledge about Butterfly Valve
Butterfly Valve is composed of pneumatic actuator and Universal Valve. Butterfly Valve is a pneumatic valve that uses a circular butterfly plate that rotates with the valve body to open and close to achieve the activation action. It is mainly used as a cut-off valve. It can also be designed to have the function of regulation or segment valve and regulation. Currently, the Universal Valve is used in low pressure It is increasingly used on large and medium diameter pipes.
A detailed introduction to the Throttle Valve
Throttle Valve are generally fully open and fully closed. Considering the flow characteristics, Throttle Valve and Ball Valve have the characteristics of short opening and closing stroke, fast speed, reliable sealing, and small opening and closing static torque. Therefore, both types of products are used. However, from the perspective of reliability, the mainstream product is still the Universal Valve.
What are the requirements for selecting a Globe Valve?
The Universal Valve drives or controls the main valve by discharging the medium from the pilot valve. The pilot valve itself is a standard spring loaded direct Globe Valve. Globe Valve are automatic valves and are mainly used in boilers, pressure vessels and pipelines to control pressure not to exceed specified values and play an important protective role in personal safety and equipment operation. According to the opening height of the Globe Valve, it can be divided into micro start Globe Valve and full start Globe Valve.
Under what circumstances cannot the compressor Globe Valve be used?
Whether something is useful sometimes depends on where it is. If the Universal Valve is not used well, it will be a big safety hazard. The Globe Valve is such a product. Below, the editor of Universal Valve will introduce to you the circumstances under which the Globe Valve for compressors cannot be used. ①The pressure will increase rapidly, and the discharge speed of the Globe Valve is less than the
Analyze the characteristics of the Relief Valve opening action
Relief Valve are divided into full-lift type and micro-lift type according to the different opening heights of the valve disc. They rely on the elastic pressure of the spring to lock the valve's valve flap or plunger and other seals. Once the pressure in the pressure vessel is abnormal, a Relief Valve will The high pressure will overcome the spring pressure of the Relief Valve, so the locking device is pushed open, forming a pressure relief channel to release the high pressure. The full-lift type has a large discharge capacity and good resilience, and is suitable for liquid and gas media
How do we close the Relief Valve?
The Relief Valve is simple and reliable in structure, sensitive in action, small in size and light in weight; it is suitable for use as a cut-off device on pipelines of steam, air and other media with a working temperature of ≤200°C, as well as toxic gases or vapors. When the pressure reaches the specified value, the spring is compressed to close the Universal Valve. When the pressure drops to a certain level, the spring returns to its
