TQ41F spring automatic reset ball valve
Spring automatic reset ball valve is a commonly used control valve, which realizes the automatic reset function by compressing the spring. This paper will introduce the basic principle, structure and application of the spring automatic reset ball valve.
First, the basic principle
Spring automatic reset ball valve through the role of the spring to achieve automatic reset. In the normal working state, the spool is in the closed position, and the spring is compressed. When it is necessary to open the valve, the piston or handle applies force to the spool to overcome the elastic force of the spring to make it open. When the handle or piston is released, the spool automatically returns to the closed position due to the action of the spring.
Ii. Structure
Automatic spring reset ball valve is mainly composed of valve body, valve cover, spool, spring and other components. Among them, the spool is spherical and can be rotated along the central axis to control the flow. The valve body and valve cover are usually made of cast steel or stainless steel, with high corrosion resistance. Springs are usually made of stainless steel or other corrosion-resistant materials.
3. Application
Spring automatic reset ball valve is widely used in water treatment, petrochemical, food and beverage, pharmaceutical and other industries, commonly used to control flow or prevent backflow occasions. Among them, some applications require high-precision control, in this case, the adjustable spring automatic reset ball valve is usually used.
Four, precautions
1. Before installation, the valve needs to be cleaned and inspected to ensure that there are no impurities or damage.
2. In the process of use, the valve should be avoided by impact or vibration, so as not to affect its normal work.
3. The valve may leak or fail to close after a long time of use, at which time it is necessary to repair or replace parts in time.
4 In the purchase of valves need to choose the appropriate model and specifications according to the specific use of the occasion, and install in strict accordance with the installation instructions.
In short, the spring automatic reset ball valve is a commonly used control valve, which realizes the automatic reset function by compressing the spring. It is usually composed of valve body, valve cover, valve core, spring, etc., widely used in water treatment, petrochemical, food and beverage, pharmaceutical and other industries. In the use of the process need to pay attention to installation and maintenance, to avoid affecting its normal work.
