advanced valve solutions valves include vacuum ball valves, vacuum gate valves, vacuum venting valves, pneumatic vacuum valves, etc. Their function in a vacuum system is to change the direction of airflow, regulate the flow rate, and cut off or connect the pipeline; such vacuum system components are called vacuum valves.

advanced valve solutions valve connection method: flange connection

This is the most commonly used connection form for valves. According to the shape of the joint surface, it can be divided into the following types: 1) Smooth type: used for valves with low pressure. Easy to process 2) Male-female type: higher working pressure, medium-hard gaskets can be used 3) Tongue-and-groove type: gaskets with greater plastic deformation can be used, widely used in corrosive media, with good sealing effect. 4) Trapezoidal groove type: oval metal rings are used as gaskets, used for valves with working pressure ≥64 kg/cm², or high-temperature valves. 5) Lens type: the gasket is lens-shaped and made of metal. Used for high-pressure valves with working pressure ≥100 kg/cm², or high-temperature valves. 6) O-ring type: This is a newer flange connection form, developed with the emergence of various rubber O rings, in terms of sealing effect connection form.

advanced valve solutions valve cleaning steps

Valve components must undergo the following processes before assembly: 1) According to processing requirements, some components need polishing, and the surface must not have processing burrs, etc.; 2) All components undergo degreasing treatment; 3) After degreasing, pickling and passivation are performed, and the cleaning agent does not contain phosphorus; 4) After pickling and passivation, rinse thoroughly with pure water, ensuring no chemical residue remains; this step is omitted for carbon steel components; 5) Wipe each component dry with non-woven fabric, ensuring no lint remains on the component surface, or blow dry with clean nitrogen; 6) Wipe each component with non-woven fabric or precision filter paper soaked in analytically pure alcohol until no dirt color remains.

advanced valve solutions valve fault resolution

Ball valves have long been subjected to material scouring, causing friction and severe impact wear, failing to meet normal production requirements and shortening equipment service life. Currently, wear-resistant materials such as ceramic materials and polymer composite materials are often used to address ball valve wear, with widely applied technical systems. Polymer materials offer superior adhesion and extreme wear resistance, safely solving the drawback of frequent metal wear and ensuring normal enterprise equipment production. Moreover, the unique ceramic materials and special surface hardeners in the material provide wear resistance and physical impact resistance in the harshest dry grinding environments that surpass any steel or even tiles, and the product's non-affinity with coal makes it an ideal material for preventing coal accumulation.
