Stainless steel three-way ball valve is a relatively new type of ball valve with special structural advantages. The T-type blocks three orthogonal pipelines that can be connected to each other, thereby blocking the third channel that can be split and connected. The L-type stainless steel three-way ball valve can only connect two orthogonal pipelines and cannot maintain the third pipeline at the same time. Then, do you know what the important structure of the stainless steel three-way ball valve is? Stainless steel three-way ball valve includes a valve body, a valve core and a valve stem. One end of the valve stem of this product is connected to the valve core, and the other end passes through the valve body to connect with the outside. The driving mechanism and the stainless steel three-way ball valve adopt a four-side integrated structure, with few valve seat sealed flange connections, high reliability and a lightweight design. The stainless steel three-way ball valve core is provided with an L-shaped fourth flow channel, and the product valve body has a first flow channel that flows through the valve core and is connected. Or disconnect. The valve body of the stainless steel three-way ball valve has a valve cavity, and the product valve body is provided with flow channels for medium to flow and communicate with the valve cavity. The flow channels include the first flow channel, the second flow channel and the third flow channel. The first flow channel is coaxial with the third flow channel, and the axis of the second flow channel of the product is perpendicular to the axis of the first flow channel. The important structures of the stainless steel three-way ball valve are mainly those introduced above. When operating and using such valves, it is necessary to understand their structures.

Three-way ball valves can be classified by connection method into flanged three-way ball valves, threaded three-way ball valves, welded three-way ball valves, and clamp three-way ball valves. Functions of three-way ball valves: Equipped with valve opening position indication or closing position indication. The external pneumatic pilot has a longer service life and is maintenance-free. There is an automatically adjustable sealing gland between the overflow port and the sliding block to improve sealing performance. The angle seat structure of the valve body can achieve large flow, compact structure, and fast response. The installation and maintenance of three-way ball valves must comply with applicable safety regulations. The pipeline must be clean and tidy. Install as needed, but it is better to have the actuator facing upward. Pay attention to the flow direction. When connecting the valve, ensure alignment with the pipeline. The actuator should only be removed when specifically required by the user. Before opening or repairing the three-way ball valve, the liquid should be shut off and the air supply should be controlled to reduce the pressure in the pipeline system. Three-way ball valves are a type of pipeline switch commonly used in automatic control systems, such as various automation equipment in printing and weaving, dyeing and finishing, bleaching, food processing, cleaning, chemical industry, water treatment, medical treatment, etc. They feature low noise and reliable sealing performance.

Pneumatic three-way ball valves usually use rubber, nylon, and polytetrafluoroethylene as the materials for the valve seat sealing rings, so the operating temperature is limited by the material of the valve seat sealing rings. The shut-off function of the ball valve is realized by pressing the metal ball between the plastic valve seats under the action of the medium. The contact pressure of the valve seat sealing ring causes elastic-plastic deformation in certain areas. This deformation corrects the manufacturing accuracy and surface roughness of the three-way ball valve, ensuring the sealing performance of the ball valve. The valve seat sealing rings of pneumatic three-way ball valves are usually made of plastic. Therefore, when selecting the structure and performance of the ball valve, special consideration must be given to the fire resistance and fireproof performance of the ball valve, especially in sectors such as petroleum, chemical industry, and metallurgy. When using ball valves in equipment and pipeline systems with flammable and explosive media, attention must be paid to fire prevention and fire resistance. Pneumatic three-way ball valves are also suitable for light-duty structures, low-pressure shut-off (small pressure difference), and corrosive medium pipeline systems. Ball valves can also be used in low-temperature (cryogenic) devices and pipeline systems. The oxygen pipeline systems in the metallurgical industry require ball valves that have undergone strict degreasing. If the main line of the oil and gas pipeline needs to be buried underground, a full-bore welded ball valve is required. If regulating performance is needed, a ball valve with a V-shaped opening should be selected. In petroleum, petrochemical, chemical, electric power, and urban construction fields, metal-to-metal sealed ball valves can be used in pipeline systems with operating temperatures above 200 degrees Celsius.
