- industrial valve manufacturer Fluorine-butterfly valves is introduced: lining and lining plastic valve and valve sealing surface using the tetrafluoroethylene after installed to the steel valve body wall (moulding way This method can also be used on the pipeline, valve is not necessarily limited to use) This industrial Industrial Valves manufacturer production process is often used in all kinds of valves used in strong acid medium. Internally while valve is suitable for all kinds of strong sulfuric acid, hydrochloric acid and other corrosive medium, but using temperature can only be guaranteed within the negative 50 to 150 degrees, my company make fluorine-butterfly valves are: fluorine-butterfly gate, fluorine-butterfly butterfly valve, fluorine-butterfly cut-off valve, fluorine-butterfly valves, fluorine-butterfly check valve and other products. Lining fluoride products after the use of the industrial era, fluorine-butterfly valves in chemical plants, oil and other manufacturers have been a lot of use, because of its material properties, ensure the service life and job security, pay more attention in the process of plant suggestion. Internally due to product all kinds of valve, the opening and closing can meet demands or debug flow, has the characteristics of fast switching speed. Like fluorine-butterfly cut-off valve and open slowly, fluorine-butterfly gate such products in high pressure greatly reduced pipe water hammer phenomenon, can also make other products in the pipeline for longer service life. Fluorine-butterfly valves used to control switch of strong acid and alkali medium flow, the valve wall covered with all kinds of fluorine lining material, suitable for different medium and temperature. Fluorine-butterfly valves are not low cost, the use of the environment and its bad, go are toxic medium or strong acid medium, such as operation is not easy to cause damage to the manufacturer or operator. So use this kind of valve unit should know fluorine-butterfly valves are how to use and maintenance, to increase its use time, to prevent industrial accidents, in use should pay attention to the following items: 1, before installation, check the instructions. 2, the medium and using the environment should be applicable certification on temperature and medium range. 3, special medium should be specified before purchasing, such as easy to decompose medium or as some as temperature changes can expand the medium, this and easy to cause the explosion or valve leakage, positive for the safe use of these unstable medium implement operation. Such as join fluorine-butterfly pressure relief valve in the pipeline, automatically adjust the pressure in the pipeline. 4, keep line in use process, the temperature changes in don't have large temperature fluctuations, can deal with this problem by installing the expansion joint. 5, fluorine-butterfly valves open and close in place, don't add strong or strong close, easy to cause the valve inside four fluorine material damage. 6, valves used in flammable and explosive medium, is strictly prohibited in the case of pressure pipeline installation packing, although fluorine-butterfly valves sealing is very good, but for the sake of safety, it is better to do not install in the pipeline pressure under the condition of packing. 7, use medium if you have certain natural, to ensure the working environment within the spontaneous combustion temperature, prevent unnecessary medium combustion explosion disasters. 8, such as the pipe installation is not stable, often shake, best to stop the use of pipeline, to deal with this problem as soon as possible, lest cause fluorine-butterfly internal parts damaged. 9, part of the valve is used to adjust flow under the condition of the medium flows fast, easy to cause the sealing surface of four fluorine material damage, this kind of valve should be replaced periodically sealing parts. Due to four in 10, the use of fluorine plastic quality is soft, are often damaged by medium in the presence of hard particles, lead to poor sealing effect, also need regular maintenance to replace. 11, fluorine-butterfly valves in the process of installation, it is not to add the flange gasket, encounter had leakage of flange installation, can be directly strengthen sealing tighten the screw nut. If it is of flange sealing surface rupture or damage, should timely replace or add the gasket. 12, the Industrial Valves used on the way, if encounter turn the handle of hand wheel stuck phenomenon, debug the valve cover nut first, as there is this phenomenon, check to see if the cover is not straight, the appropriate adjustment. If the above two questions are checked, and in this way, is about to open valve check body internal situation, remove clutter and some troubleshooting in the wall. Repair this type of valve used to determine whether the pipes, such as medium is toxic or flammable should pay attention to wear protective clothing and masks, ensure the safety of personnel in the process of operation. Internally in industrial valve material, valve lining ptfe has an irreplaceable quality, in addition to the element fluorine or molten alkali metals, chemical medium can be competent for all kinds of plants, like hydrochloric acid, sulfuric acid, nitric acid, dilute acid and concentrated acid are common medium. Four fluorine material installed on the wall also solved the problem of the four fluorine material hardness is low, at the same time to deal with the valve body against the corrosion problem of poor performance, save a lot of cost. And this kind of plastic materials for industrial raw materials with strong stability, viscosity, and cover on the valve closed and the position of the seal, also can reduce friction strength of the valve, the valve switch more portable. - industrial valve manufacturer Lining fluoride valve installation instructions 1, if the pipe is open valve weight and strength, there is no need to set up support, otherwise will need to set the valve support. 2, when the valve flange installation side, such as pipe fittings made of metal, plastic gasket should be fitted, prevent the damage of the flange sealing surface. 3, the installation process, the Industrial Valves should be installed to maintain the level state, the and in the process of lifting the valve, must not lifting hand wheel or valve stem, and so easy to damage the valve. 4, pay attention to the information fluorine-butterfly valves on the certification mark, to qualify for the safe use, some valve belong to one-way traffic, attention should be paid to the valve installation direction, to avoid unnecessary trouble. 5, after the installation is complete, in the process of pressure testing, all valves should be kept fully open position.
Anyone who has seen the latest cast iron gate valve resilient seated gate valve in operation cannot help but be impressed with how far the technology has progressed over the past few years.
