Q:What's the difference between D71X-16 and D71H-16 butterfly valves?
First, model D71X model means that, on behalf of 7 representative D butterfly valve, butterfly valve connection form for clamp connections, 1 straight, X represents the seal in the form of soft sealing, the sealing surface usually NBR H metal seal is usually 2Cr13 16 represents the pressure of 16 kg pressure weldingJin Ya valve is the production of hard sealing butterfly valve or soft sealing butterfly valve line leader, what problems can ask their units, technicians will answer for you
Q:The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?
Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.
Q:What do you mean by manual butterfly valve DN100 D341X-10?
DN100 refers to the inside diameter of the butterfly valveD stands for butterfly valves3 represents the turbine drive4 represents the flange connectionThe 1 represents straight throughX is the representative of the Dengqen rubber seal10 represents the pressure of 1.0Mpa (10 kg)Manual butterfly valve, also known as turn over plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control. Butterfly valve refers to the closure of parts (valve or butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.
Q:What's the material of the butterfly valve seat?
Butterfly valve seat materials commonly used include EPDM (three yuan ethylene propylene rubber), NBR (Ding Qing rubber), PTFE (PTFE), metal sealing (cemented carbide).Their scope of application is..:1, EPDM (three yuan ethylene propylene rubber): excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor, color stability, electrical properties, oil and gas flow at room temperature. Ethylene propylene rubber products can be used at 120 degrees for a long time and can be used briefly or intermittently at 150-200 degrees centigrade.2, NBR (Ding Qing rubber): from butadiene and acrylonitrile was prepared by emulsion polymerization, nitrile rubber by emulsion polymerization at low temperature, excellent oil resistance, high wear resistance, good heat resistance, strong adhesion. Its disadvantages are poor resistance to low temperature, poor ozone resistance, poor electrical properties, and slightly lower elasticity.3, PTFE (polytetrafluoroethylene): can be used at 260 degrees for continuous use, with the highest use temperature of 290-320 degrees, low coefficient of friction, good wear resistance, and excellent chemical stability. It can not be injection molded and can be extruded or painted. PTFE's unique properties make it widely used in chemical, petroleum, textile, food, paper making, medical, electronic and mechanical industries and marine operations.4, metal seal (hard alloy): metal seal valve seat material has good resistance to high temperature, high pressure resistance, corrosion resistance and wear resistance, but the high requirements of the processing technology, the biggest drawback is the long time operation is easy to generate leakage.
Q:Fire, the signal butterfly valve flange connection or welding?
1, do a good job with flange.2, flange (Flange), also known as flange, flange plate or edge. A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures. Pipe flanges are flanges used for piping in pipe installations. They are used on equipment and refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms. Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".3, also known as welding: welding, melt, is a kind of heating, high temperature or high pressure way of metal or other thermoplastic materials such as plastic manufacturing process and technology.
Q:It is different from the butterfly valve butterfly valve
How it works: the disc is driven by the stem, and if it turns 90 degrees, it can be opened and closed once. By changing the deflection angle of the plate, the flow of the medium can be controlled. The main sealing element is a sealing ring, and the material is selected according to the use and the medium.
Q:How can one - way sealed butterfly valves and two-way sealed butterfly valves be distinguished?
Two way hard sealing butterfly valve:Two way butterfly valve on the valve body usually does not indicate the direction of the media arrow sign, in the design of two-way sealing butterfly valve stem force is greater than one-way butterfly valve stem. The same diameter, pressure butterfly valve, two-way sealing butterfly valve rod diameter than one-way sealing butterfly valve stem diameter. At the time of installation, the butterfly plate can face or back the direction of the medium, without considering the flow direction of the medium.
Q:Is a valve adjustment necessary on my vulcan 500 motorcycle?
First off you are suppose to take your bike back to have your valves adjusted after 500 miles. Anything later can cause problems. The motor is already broken in. why did you wait so long to have them adjusted ? Your vibration is the tire is not balanced right , take it else where. good luck
Q:What are the functions and uses of butterfly valves?
Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.
Q:Butterfly valve sealing material has several?
9: H- stainless steel composite layerX3- ethylene propylene rubberX4- chloroprene rubberX5- nitrile rubberX6- abrasion resistant rubberX7- fluorine rubberX8- silicone rubberX9- heat resistant ethylene propylene rubberF- PTFE
