Function And Use Of Sanitary Ball Valve
Functions and Uses of Sanitary Ball Valve:
① Double-ball valves play a critical role in city gas supply systems. Gas travels from the source to every household through a long and complex network of pipelines. To ensure a safe and stable supply, city gas mains are equipped with double-ball valves. When a section of pipeline requires maintenance or an emergency occurs, the double-ball valve can be operated to quickly shut off the gas supply, preventing dangerous gas leaks. For example, during pipeline maintenance, one of the double-ball valves near the maintenance point is closed first. Once safety is confirmed, the other is closed. This double-safety ensures a gas-free area, ensuring the safety of maintenance personnel while minimizing the impact on gas supply to surrounding users.
② Double-ball valves are indispensable in centralized heating systems. High-temperature hot water from large heating equipment is delivered to individual households via main and branch lines. Installing double-ball valves on these heating pipes allows for precise control of the flow and direction of hot water. During the initial heating period, the hot water flow is adjusted by adjusting the opening of the double-ball valves, gradually stabilizing the heating system. If a branch heating line experiences a problem, such as a ruptured pipe, the double-ball valve on that branch line can be closed immediately, blocking the flow of hot water and preventing wasteful, potentially hazardous, leaks without disrupting heating in other areas.
③ In the piping system of a heat exchanger, double-ball valves are used to control the opening and closing of each circuit. Heat exchangers require the flexibility to adjust the operating status of each circuit based on actual needs. For example, in the central air conditioning systems of some large commercial complexes, heat exchangers provide heated and cooled air to different areas through different circuits. Using double-ball valves, staff can easily open or close specific circuits to independently adjust the temperature of each area. When a certain area does not require heating or cooling, the corresponding double-ball valve circuit is closed, saving energy and improving energy efficiency.
④ Within steel mills, complex fluid pipelines exist. Double-ball valves can be used to control a variety of fluid media. For example, in the high-temperature exhaust gas discharge pipes generated during blast furnace ironmaking, installing double-ball valves effectively controls exhaust emissions. When exhaust gas treatment equipment requires maintenance, closing the double-ball valves prevents further exhaust gas from entering the equipment, facilitating repair work. In gas and heat supply pipelines, double-ball valves ensure stable gas and heat delivery, promptly shutting off the system in the event of a fault, and preventing gas leaks from causing explosions or thermal runaway accidents.
⑤ In the petrochemical industry, double-ball valves are widely used. The transportation and processing of crude oil, heavy oil, and other oil products require precise flow and pressure control. For example, in refineries, double-ball valves are installed on the pipelines that carry crude oil from the tanks to the distillation unit. This allows precise adjustment of the flow rate of crude oil into the distillation unit based on production needs, ensuring a stable production process. Furthermore, many media in chemical production are corrosive. The special materials and sealing design of double-ball valves are suitable for these corrosive media, preventing leaks and ensuring production safety.
⑥ In sewage treatment plants, double-ball valves are used to control the direction and flow of sewage. The sewage treatment process involves multiple stages, with sewage passing through different treatment tanks in sequence. Installing double-ball valves on the pipelines connecting the treatment tanks allows workers to flexibly control the amount of sewage entering each tank based on the treatment process requirements. For example, when transferring wastewater from the regulating tank to the aeration tank, a double-ball valve regulates the flow rate to maintain the appropriate wastewater volume and dissolved oxygen content within the aeration tank, improving wastewater treatment efficiency and ensuring that treated wastewater meets discharge standards.
⑦ In the food and beverage industry, sanitary double-ball valves are used to ensure hygienic safety during the production process. For example, in the production of liquid products such as milk and juice, strict sanitary conditions are required throughout the entire production line, from raw material delivery to finished product bottling. Double-ball valves, made of materials that meet food hygiene standards, offer excellent sealing properties and effectively prevent product contamination. During production, double-ball valves control the flow of raw materials and additives, ensuring accurate product formulations. Furthermore, during equipment cleaning and maintenance, the double-ball valves are closed to prevent impurities such as cleaning fluids from entering the product.
⑧ Double-ball valves are also crucial on pharmaceutical production lines. Pharmaceutical production places extremely high demands on the environment and production processes. Double-ball valves are used to control the delivery of pharmaceutical raw materials, intermediates, and finished products. For example, in the production of injectables, raw material liquids are transported through pipelines to reactors, filtration equipment, and bottling equipment. Double-ball valves precisely control the flow rate to ensure consistent drug quality. Their excellent sealing and hygienic properties prevent microbial contamination, comply with pharmaceutical manufacturing quality management standards, and ensure the production of safe and effective pharmaceuticals.
⑨ In ship piping systems, double ball valves are used to control the flow of various media. Ships require fuel, lubricating oil, cooling water, compressed air, and other media to maintain normal equipment operation. Installing double ball valves on fuel supply pipelines allows precise adjustment of fuel flow based on the ship's engine operating status, ensuring stable engine operation. When engine maintenance is required, the double ball valves can be promptly closed to cut off the fuel supply and ensure safe maintenance. In cooling water pipelines, double ball valves regulate cooling water flow and control engine temperature, preventing overheating and damage.
⑩ In building water supply and drainage systems, double ball valves are used to control water flow. In high-rise building water supply systems, double ball valves are installed in different sections of the water supply pipeline to ensure stable water pressure on different floors. If a leak or other problem occurs in a pipeline on a certain floor, the double ball valve in the corresponding section can be quickly closed to cut off the water supply and allow repairs to be carried out, minimizing the impact on water use on other floors. In drainage systems, double-ball valves can be installed at the junction of vertical and horizontal drainage pipes to prevent wastewater from backflowing into the room when drainage is blocked, thus ensuring indoor sanitation.
⑪During the heat treatment process of industrial equipment, double-ball valves are used to control the flow of cooling media. Some metal parts require rapid cooling after heat treatment to achieve specific mechanical properties. Using double-ball valves to regulate the flow of cooling media (such as water or oil) allows for precise control of the cooling rate and ensures part quality. For example, in heat treatment workshops for automotive engine parts, workers use double-ball valves to adjust the cooling media flow based on the part material and heat treatment process requirements to achieve the desired performance indicators such as hardness and strength.
⑫In some locations with special gas transportation requirements, such as semiconductor manufacturing workshops, high-purity, flammable, explosive, or toxic gases need to be transported. Double-ball valves can be used to control these gas pipelines. Their excellent sealing performance effectively prevents gas leaks and ensures a safe production environment. During gas transportation, adjusting the double-ball valve opening allows for precise control of gas flow, meeting the stringent gas volume requirements of the production process and ensuring stability and product quality in the semiconductor manufacturing process.
