Supporting base product is currently widely used in the world, forming the casting process

Support base is a key and important part of the railway bogie truck on its product quality and performance of the railway wagon speed , overloading has an important impact . Supporting base product is currently widely used in the world, casting forming. In recent years , with rail transport to improve on overloading, high-speed requirements of the key components of the support base is also increasing  Stainless steel needle valve  inherent product defects steel support base exists ( the mechanical properties of steel castings itself , fatigue toughness, resistance impact is not high , casting products exist unavoidable porosity , shrinkage , inclusions, cracks, etc. ) for the safe operation of high-speed rail has been a threat. Improve the overall mechanical properties of the product 's support base is a major reform and structural adjustment of China's Ministry of Railways to resolve rail transport facing the implementation of overloading, speed , security,  Instrument manifolds  , major issues need to be addressed to improve the effectiveness and efficiency of transportation . To ensure the safety and reliability of the rail wagons running speed , the paper creatively put forward the reform of the support base cast- forging process solutions to improve their mechanical properties. Since the original steel support base products of complex shape , casting the presence of high-gluten product support base , thin-walled structures , to bring support base increased difficulty forging casting change .

Research on heat transfer process plays a very important role in the development of the engine

Due to new technologies such as new combustion system, pressurized, low loss, high strengthen,  Instrumentation ball valve  and the use of alternative fuels, resulting in increased engine heat load. Therefore, the study of heat transfer process plays a very important role in the development of the engine . heat load leads to critical engine parts, such as  Instrument manifolds , pistons, cylinder heads and other thermal fatigue failure, affecting the safety and reliability of the engine is running this paper flow - solid coupling method on the engine exhaust manifold heat stress analyzes, the results of the analysis presented manifold improvements.

The exhaust manifold is the most important part of the engine exhaust system

The exhaust manifold is the most important part of the exhaust system of the engine , the engine is in the middle of the engine exhaust system and the subsequent coupling hub. Since the cylinder head and the engine is directly connected , in the role of high-temperature exhaust gas discharged from the engine , the larger the impact hot exhaust manifold . The complex structure of the exhaust manifold and the temperature distribution is uneven, has long been under the joint action of  Instrument manifolds  and alternating stresses , easily lead to heat crack initiation and expansion , and with the requirements of lightweight vehicles , many of the exhaust manifold by thin-walled tube made ​​. Therefore, in the design and development process of the exhaust manifold , an important guiding significance for its thermal load research . First, based on the engine parameters and  Stainless steel needle valve layout assembly, 3D modeling software application to establish a model of a gasoline engine exhaust manifold . Secondly , the United CFD simulation software and FEA analysis software to predict the exhaust manifold at rated conditions of temperature field, thermal stress and deformation. Finally, the simulation engine in the normal operation state and stop the cooling cycle two , an equivalent plastic strain as the reference standard , the reliability evaluation manifold . The results show that the exhaust manifold is closely related to the complexity of the conditions of temperature distribution and heat and exhaust manifold , exhaust manifold heat stress release focused on the stiffness of the weak structure transition region.

Valve in the automatic control system should

The rapid development of automation and control, makes the valve in the automatic control system more widely. In recent years, metallurgy. Cement, building materials and other industries ventilation and dust removal system media flow regulation, they use  Instrument valve manifolds  valve. Its basic principle is: the set of physical sensors on the pipeline, the detected physical quantity by digital / analog  Instrument manifolds , into the electric actuator, electric actuator compare this signal amplified to drive two-phase servo motor rotation, automatic actuation of the valve on or off at an angle, complete medium flow control. Because the system automatically adjusts the valve or pipeline design in some areas is not reasonable, during operation, a number of valves, especially large diameter valves failure often occurs in varying degrees, of which the highest failure rate when the number of servo motor damage.

Width electric drive technology to guarantee greater lever control functions

Width in monthly electric drive rod technology ensures greater control functions , cleaner perform tasks , providing closer spacing and pitch to ensure better quality pouring n, thereby reducing the amount of maintenance . Xiang drive valve gate hot runner system stem new  Instrumentation ball valve  available, it is an effective solution. From the traditional sense, hot runner system can be used both pneumatic , hydraulic methods can also be used to drive and control the valve gate opening and closing . For certain applications , these two techniques are very useful , and the new electric drive technology has stronger stem control function, can perform tasks more cleanly , providing closer pitch spacing and ensuring a more quality gate , thereby reducing the amount of maintenance , to mold manufacturers to  Instrument manifolds . Power-driven valve gate system is a combination of pneumatic and hydraulic technology . Both belong to the traditional system very effective techniques that distinctive, for customers , the electric system represents the perfect combination of these two technologies . This technology uses an electric servo motor drive , which can open and close the valve stem accurately . The development of this technology is very timely , because in the past few years, the electric servo motor technology has matured . All-electric injection molding machine is the driving force for another unit of this technology .

Valves meet the safety of the premise, to be affordable

Water flooding the ground water flow control valve has three basic requirements: First, adjust the water valve is convenient, accurate and easy to formation water flood front uniform steady advance ; Second valve to corrosion, erosion ; Third valve meet the security of the premise, to be affordable . In the oil field water operations,  Instrument manifolds  ground water injection regulating valve , the use of gate or needle valve, these two valve control performance is poor, poor corrosion resistance , can not meet the requirements of the scene , seriously affecting the normal production of oil . In response to this situation , Production  Instrument valve manifolds  Institute of Xinjiang Oilfield Company, through theoretical design and a series of laboratory and field trials , successfully developed a water flow control valve , the valve corrosion, erosion, can be easily and accurately regulate ground water injection and affordable , easy operation and maintenance , to meet the demand for oilfield different forms of water . Structure mainly by the water flow  3 way manifolds  flange , valve , pin , fixed disk , moving disk , valve, disc spring, the filter plate and the handle and other components , the water flow control valve by sealing the valve body and the flow regulator 2 done in close contact with the ceramic disc , when the disc 2 is completely aligned over the orifice , the control valve is fully open state , turning the handle , moving the disk drive rotates , holes, decreasing the flow area .
