Main Features of PPR Pipe
PPR pipe called three polypropylene tube and called random copolymer polypropylene tube or pipe PPR, which has energy-saving materials, environmental protection, high-strength lightweight, corrosion-resistant, smooth wall does not scale, simple construction and maintenance, service life long, it is widely used in building water supply and drainage, urban and rural construction, municipal, industrial and agricultural areas of water supply and drainage, city gas, electricity and cable jacket, industrial fluid transport, agriculture and irrigation.

- Q: What are the differences between the pneumatic ball valve and the pneumatic angle seat valve?
- Pneumatic angle seat valve is the use of reciprocating actuators, usually in use to withstand fluid work pressure at 1.6MPa. Pneumatic ball valve is to use rotary actuator, to bear high fluid pressure. In normal use, the reciprocating actuator is characterized by its service life over the length of the rotary actuator. Two: easy maintenance. Three: the price is cheap. Personal recommendations in fluid pressure below 1.6MPa, or pneumatic angle seat valve is better?. High pressure, less opening frequency, pneumatic ball valve is appropriate.
- Q: How many kinds of ball valves are there?
- Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. Classification of ball valve: pneumatic ball valve, electric ball valve, manual ball valve.
- Q: Can the ball valves be used in heating?
- Heating can be used.Ball valve (ball valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve for rotation of the valve.". Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media.
- Q: What are the advantages and disadvantages of the two functions of the pneumatic ball valve actuator?
- Pneumatic ball valve actuator is divided into double action and single action two modes of work.Working principle of double action mode:When the compressed air enters the middle cavity between the two pistons of the cylinder from the air inlet (2), the two pistons are separated and moved toward the two ends of the cylinder, and the air at the two ends of the air chamber is discharged through the air port (4). At the same time, the two piston rack synchronously drives the output shaft (gear) to rotate in an anticlockwise direction. On the contrary, when the air source pressure passes through the air inlet (4) into the air chamber at the end of the cylinder, the two piston moves toward the middle of the cylinder, and the air in the middle air cavity is discharged through the air port (2). At the same time, the two piston rack synchronously drives the output shaft (gear) to rotate in clockwise direction. (if the piston is mounted in opposite directions and the output shaft rotates in reverse direction, that is, double acting reverse type).
- Q: What does the RTFE say in the ball valve?
- RTFE reinforced PTFE is more wearable than PTFETeflon PTFEThe seat of tetrafluoroethylene specified for a temperature range of ~200 DEG C -32. High temperature resistance and chemical resistance. Because of its high density and good permeability, PTFE can also prevent the corrosion of most chemical media.Conductive PTFE is an improved PTFE product that allows the current to pass through the lining and thereby cancel the insulation properties of ptfe. Because of its conductivity, conductive PTFE can not be checked by edm.+ reinforced PTFE RTFERTFE is a modification of PTFE material. Pure PTFE although very low coefficient of friction (0.02~0.04) but the wear volume is great, but also because of its easy creep, poor mechanical properties, low bearing capacity, poor dimensional stability characteristics such as friction material has great localization. Only modified by compound method to meet the special requirements of all walks of life sealing material on the wear resistance, to improve the wear resistance of PTFE, can be incorporated into some wear-resistant materials such as glass fiber, carbon fiber, graphite, molybdenum disulfide, bronze powder and some organic compounds, making them reticular junction formed in the PTFE layered structure so as to improve the the stiffness, thermal conductivity, creep resistance, and greatly improve the wear resistance.PTFE is composed of tetrafluoroethylene monomer polymerization of the polymer, the wax is similar to a PE transparent or opaque, its density is 2.2g/cm3, the water absorption rate of less than 0.01%. Its chemical structure is similar to that of PE, except that all hydrogen atoms in polyethylene are replaced by fluorine atoms. Because the C-F bond is high and stable in performance, it has excellent chemical resistance
- Q: Would you please tell me why the spring is placed in the valve seat? What's the function?
- Valve seat on both sides should be added spring, the seal pushed to the valve core to seal up, so put the spring.
- Q: What's the difference between a copper ball valve and a stainless steel ball valve?
- Professional definition of copper ball valve:The copper ball valve itself is compact, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also applies to poor working conditions of media, such as oxygen hydrogen peroxide, methane and ethylene, widely used in various industries. Ball valve body can be integrated, or can be combination.Stainless steel ball valve professional definition:The main characteristics of stainless steel ball valve itself is compact, easy operation and maintenance, stainless steel ball valve can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. Ball valve body can be integrated, or can be combination. This kind of valve should be installed horizontally in the pipeline. Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. Stainless steel ball valve is divided into 304316321 stainless steel ball valve.
- Q: What is the nominal pressure 1.6p of a ball valve?
- Nominal pressure PN is a digital indication of pressure related signs, which is a convenient round integer for reference. All pipe attachments of the same nominal diameter indicated by the same nominal pressure PN have the same connection dimension as the end connection type.
- Q: Valve and ball valve is the same thing? Don't know don't speak
- Ball valves belong to a large class of valves, valves include gate valve, butterfly valve, check valve, globe valve, ball valve, trap valve, safety valve, etc. all valves
- Q: What is the ball valve Q11F -16 material?
- If sealed, F stands for fluoroplastic. Valve material is not marked in the model!Q stands for ball valvesThe first 1: threaded connection,Second 1: is the ball valve is floating through the ball,F stands for PTFE- PTFE seals16 represents the nominal pressure of the ball valve is 1.6MPa=16 kg
