Plastic ball valve features and application profile

July 13, 2021
RMIPLAST Plastic ball valve features: (1) high working pressure: a variety of materials at room temperature working pressure up to 1.0Mpa. (2) the use of temperature: PVDF temperature of -20 ℃ ~ +120 ℃; RPP temperature -20 ℃ ~ +95 ℃; UPVC temperature -50 ℃ ~ +95 ℃. (3) good impact performance: RPP, UPVC, PVDF, CPVC has a high mechanical strength and impact resistance. (4) liquid flow resistance is small: the product wall is smooth, the friction coefficient is small, conveying efficiency. (5) excellent chemical performance: This product non-toxic, tasteless, acid and alkali, corrosion resistance, the use of a wide range. PPR is mainly used in food, beverage, tap water, pure water and other sanitary requirements of the liquid pipelines and equipment, can also be used for corrosive liquid pipes and equipment; RPP, UPVC, PVDF, CPVC is mainly used for corrosive acid , Alkali and mixed acid liquid (gas) body circulation. (6) Easy installation, good sealing: The product is light, the use of bonding or welding, pipe fittings complete, easy construction, good sealing, labor-saving plastic ball valve is characterized by its compact structure, reliable sealing, simple structure, Easy maintenance, sealing surface and the spherical surface is often closed, easy to be media erosion, easy to operate and repair, suitable for water, solvents, acids and natural gas and other general working medium, but also for poor working conditions medium such as oxygen, Hydrogen peroxide, methane and ethylene, etc., are widely used in various industries. Ball valve body can be a whole, it can be combined. Plastic ball valve advantages: body weight, corrosion resistance, such as: pure water and raw drinking water piping systems, drainage and sewer piping systems, salt water and sea water piping systems, acid-base and chemical solution systems, etc. industry. ※ compact and beautiful appearance structure ※ body weight light easy to install ※ strong corrosion resistance, wide range of applications ※ material health non-toxic ※ wear-resistant, easy to disassemble, easy to maintain ● suitable fluid: water, air, oil, corrosion The way to connect the liquid plastic ball valve to the pipeline system is the butt welding connection: the outer diameter of the connecting part of the valve is equal to the outer diameter of the pipe, and the end face of the connecting part of the valve is welded to the end face of the pipe; the socket is bonded and connected: For the socket form, and pipe fittings for bonding connection; fused socket connection: the valve connecting parts for the inner diameter laying electric wire socket form, and the pipe fused connection; socket hot melt connection: valve connection parts for the socket form , And the pipe hot melt socket connection; socket adhesive connection: the valve connecting parts for the socket form, and the pipe for bonding socket connection; socket rubber seal connection: the valve connecting parts for the inner rubber seal Socket form, and the pipe socket connection; flange connection: the valve connection parts for the flange form, and the flange on the pipe into Connection; threaded connection: threaded joints in the form of a valve, to connect with the threads on the pipe or tube; Union connected: to the valve union joints form connect with the pipe or fitting. A valve can have different connections at the same time. The relationship between the use of pressure and temperature With the use of temperature increases, the service life of plastic ball valves to be shortened. In order to maintain the same life, you need to reduce the use of pressure. Plastic ball valve installation and maintenance should pay attention to the following matters 1, to leave the valve handle rotation position. 2, can not be used for throttling. 3, with the ball valve drive mechanism should be upright installation. With the increasing proportion of plastic pipe in hot and cold water supply and industrial pipe engineering applications, quality control of plastic ball valves in plastic pipe systems is becoming more and more important. Due to the plastic ball valve has the advantages of light weight, corrosion resistance, non-adsorption scale, integration with the plastic pipe and long service life, plastic ball valve in the water supply (especially hot water and heating) and other industrial plastics Pipeline system, the advantages of its application is that other valves can not be compared. Currently in the domestic production and application of plastic valves, there is no reliable method of its control, resulting in water supply and industrial use of other plastic ball valve fluid uneven quality, resulting in engineering applications closed lax and leakage is serious, The formation of a plastic valve can not use the remarks, affecting the overall development of plastic pipe applications. China's national standard plastic valve is being developed in the process, the product standards and method standards are based on international standards. The main types of plastic valves in the world are ball valves, butterfly valves, check valves, diaphragm valves, gate valves and globe valves. The main types of structure are two-way, three-way and multi-way valves. C, PB, PE, PP and PVDF and so on.
