Product Overview:The CS15H free semi-float ball steam trap is suitable for steam heating equipment and steam pipelines. It automatically discharges condensate, prevents steam leakage, and automatically removes air. Widely used in chemical, petroleum refining, power, light textile, papermaking, and other industrial enterprises, it is particularly suitable for steam equipment with low pressure, high discharge capacity, high temperature stability requirements, and where condensate should not accumulate.II. Working Principle:When the steam trap is not in operation, the free semi-float ball rests on the emission tube. When the trap is in the drainage state, steam enters the valve body through the filter and emission tube. As the steam volume increases, buoyancy causes the semi-float ball to rise. Under steam pressure, the semi-float ball closes against the drain nozzle, preventing steam escape. When a large amount of condensate enters the valve body, the steam volume inside the semi-float ball decreases, causing it to descend under its own weight and detach from the drain nozzle, completing one working cycle. This process repeats continuously to achieve automatic drainage and steam blocking.III. Structural Features:The internal structure has only one semi-float ball bucket as the moving part, with the opening facing downward. The outer surface of the semi-float ball bucket is finely ground, and the entire spherical surface serves as the sealing surface. It has a long service life, is resistant to water hammer, has no vulnerable parts, is trouble-free, durable, prevents steam leakage, and offers excellent energy-saving performance. The free semi-float ball steam trap is used for steam heating equipment and steam pipeline condensate recovery systems.Free Semi-Float Ball Steam Trap Imported National Standard CS15H  CS45H Carbon SteelIV.

Product Description: A flameless explosion venting device is a safety apparatus designed to protect equipment and personnel by automatically shutting down equipment or pipelines in the event of an explosion or fire, thereby preventing the spread of flames or escalation of the explosion. Its operational principle involves monitoring changes in gas pressure and temperature inside pipelines or equipment to detect potential explosion or fire hazards. Upon confirmation of danger, it immediately closes the equipment or pipeline while releasing pressure to safeguard both machinery and personnel.Pipeline Emergency Venting Device (Flameless Explosion Vent) Brief Introduction:1. It consists of two parts: an explosion vent panel and a flame arrestor module;2. Suitable for indoor equipment dust explosion flameless venting. High venting efficiency, cost-effective and practical;3. Effectively blocks flames and heat, providing a safe environment for equipment, buildings, and personnel, while also collecting dust to reduce environmental pollution;4. Combined use with explosion isolation valves not only prevents pressure waves and flames from propagating to upstream workshop areas but also mitigates secondary explosion incidents, reducing property damage and ensuring personnel safety.Product Parameters:Static activation pressure: 0.01 MPa;Frame material: Carbon steel or stainless steel;Flame arrestor material: 304SS;Applicable dust: St1 and St2 dust with Kst ≤ 300 barg·m/s, effective venting area meets explosion venting requirements;Product classification: Based on application scenarios, it can be divided into rectangular flameless explosion venting devices and curved flameless explosion venting devices;Applicable equipment: Dust collectors, bucket elevators, drying equipment, cyclones, dust collectors;Industries: Wood processing, plastics, spray painting, food and dairy, plastic and dye processing, grain storage and processing, pharmaceuticals, coal processing, brewing, chemicals, metal processing, chemicals, power, cement, and other industries.Pipeline Emergency Venting Device (Flameless Explosion Vent) Working Principle:The flameless venting device consists of two parts—an explosion vent panel and a flame extinguishing module. The explosion vent panel responds to rapid increases in deflagration pressure, immediately opening to reduce pressure. When the expanding fireball passes through the open vent panel, it is intercepted by the flame extinguishing module. The precision stainless steel mesh, supported by a frame, acts as a three-dimensional flame trap, extinguishing the flame and preventing propagation, thereby avoiding secondary or multiple explosions. The flame extinguishing module eliminates deflagration flames, reduces the temperature of hot gases, and captures both burning and unburned dust passing through the open vent panel.Simultaneously, pressure waves or noise generated by production equipment are significantly reduced. As flames pass through the mesh flame arrestor element, heat exchange occurs, rapidly cooling the high-temperature flame, venting pressure and smoke, while also reducing pressure waves or noise from production equipment.Application Fields:Widely used in industries such as grain, metallurgy, chemicals, power, light industry, tobacco, pharmaceuticals, machining, and solid waste treatment. Applicable equipment includes cyclones, bag dust collectors, dust collectors, cartridge filters, pneumatic conveying systems, rod or ball mills, bucket elevators, dryers and ovens, roller grinding, buildings, etc.With increasingly stringent environmental inspections, safety has become a major concern. In the past, explosion vent panels were commonly installed on dust collectors to release overpressure caused by dust explosions. However, such installations on indoor equipment are not permitted by safety regulations because they endanger surrounding personnel and equipment. The pressure waves and flames from an explosion could trigger secondary or multiple explosions, posing risks. Therefore, relying solely on explosion vent panels for dust collectors is unreliable. We recommend using flameless explosion venting + isolation technology (a more economical solution) or explosion suppression + isolation technology to ensure production safety.There are three main methods for dust explosion protection: venting, isolation, and suppression.Venting: Releases explosion pressure in advance through a pressure relief device to protect equipment from damage.Isolation: Uses an explosion isolation valve to block the explosion and prevent flame propagation.Suppression: Detection devices identify sparks and trigger fire suppression systems to instantly extinguish flames, preventing explosions. more>
