Plastic air intake manifolds that is the vehicle structural member is complex, and requires high functional element is

Automotive plastic has the general trend garnish and upholstered structure and function of the steering member, i.e., the plastic intake manifold is very complex automotive structural parts and functional parts are demanding. At present, the domestic design and manufacture of plastic intake manifold technology does not pass. This article is part of the research and development of plastic intake manifold methods. For the domestic is still not self-designed plastic intake  Instrument valve manifolds  mold. Authors believe that the use of CAE technology must advance on plastic intake manifold injection molding process simulation study, in order to achieve the success of this mold design. For plastic intake manifold,  Valve manifold  is difficult. Firstly, the Charade car engine carried a plastic intake manifold runner design simulation, mainly studied under different program number and location of the deformation, bubbles, weld lines, etc., come in the form of four water filling points for the best and to determine the best location of the gate.

The sampling device built experimental platform, the use of computer testing system, made ​​a lot of model validation experiments

In the preliminary design and manufacture of sampling device for the study, that the simulation platform, the establishment of the new sampling device simulation model. In order to verify the correctness of the simulation model, the authors of the sampling device built  Instrument valve manifolds  platform, the use of computer testing system, made ​​a lot of model validation experiments. Experimental results show that the authors constructed a  Valve manifold  model is correct, can be used as a basis for 2 way manifolds . Since the authenticity of systematic sampling of materials depends largely on the stability of the sampling rate of the car, so the author based on the simulation model, the process of reclaiming speed stability issues detailed study draws some important conclusions. Its main tasks are: Introduction to sampling system structure and working principle, a simulation model of the system, and using the model to analyze the sampling process speed load characteristics;

Fluid control valve is an important safety element engineering

Nuclear energy is energy efficient in the world energy mix has occupied the position can not be ignored , so the safety of nuclear power plants has also been referred to the new height . Nuclear power plants are large and complex hydraulic system hydraulic control system , the system is strictly prohibited countercurrent many  Stainless steel needle valve  , or it may lead to serious accidents, therefore , require a lot of system -return element . Fluid control valve is an important safety component engineering , it is through closing fluid countercurrent to ensure directional flow of fluid , which protects other fluid machinery and pipeline safety . Therefore, in the nuclear power plant hydraulic system has been widely  Instrument needle valves  of non-return valve , such as swing check valves . Swing check valve has a disc-type plug hinged on the edge , through the back off. Because of its simple design , low price, good economy , high reliability, easy maintenance and daily wide range of sizes , etc., the valve in the nuclear Valve manifold  are widely used , the impact of the piston slam shut valve overpressure has been generated as experimental measurements and models to study the subject . Thus, the conventional movement of the check valve member (i.e., the valve head or valve ) to do the speed often rapidly opening and closing movement , the valve itself which is necessary features .
