Experimental test evaluation of valves
In the CNC machining industry, in addition to metal CNC machining, plastic CNC machining is also relatively common. The two are also very different in terms of machining, the selected tools are also different, and there are also essential differences in speed and cooling. Due to the internal stress of the plastic, it is easy to crack and deform, so in the process of processing, it is necessary to control the speed of the tool and the problems of cooling. In short, CNC machining of metal parts and plastic parts is essentially different in the selection of tools, programming of tool paths, determination of tool speed and determination of cooling schemes. It is necessary to fully select and design materials according to material characteristics and processing experience. Only by determining various factors can we produce efficient and qualified products.
Machining metal parts and machining plastic parts are two separate departments at SCZY, each with its own processing equipment, tools and processing technicians. This ensures the durability of the equipment and the experience and professionalism of the technicians. Please contact us to discuss CNC machining knowledge.

Key words: valve; experimental test; evaluation preface In this paper, the problems existing in the experimental inspection work of the current valve and its causes are analyzed in detail. Based on this, the corresponding solutions are proposed. The main reason is to introduce this part. It is because the research on valves at home and abroad is very important, especially the experimental inspection, and it is constantly researching. If we want to have a place in the big environment, we must improve the experimental inspection of the current valve in China, and pay great attention to the shortcomings in it. The safety of the valve and other performance improvements can not only be used for many enterprises. The development of assistance, the most important thing is to be able to protect the environment while developing the economy, which is the focus of research.
1. The cause of the problem in the experimental inspection of the valve 1.1 The establishment of the experimental inspection standard is still incomplete. The experimental inspection of the valve is a very important part of the valve production process, which can timely find the quality, safety and other aspects of the valve. Whether the problems in the aspect meet the needs of actual use, so this is a non-negligible content. However, at present, the work done by relevant industries in China is still insufficient. First of all, there are serious problems in the formulation of experimental test standards, which makes the test standards unreconcilable. Then there is no way to implement them into the actual test and play no role. . Even if the valve has quality problems, because the inspection standards are not perfect, it is impossible to determine these problems, and it is impossible to carry out corresponding improvement measures. This problem is mainly caused by insufficient attention of the state, and the degree of attention of the management department is not enough. There is no correct understanding of the experimental test of the valve, and the formulation of relevant standards is neglected. Combined with the above reasons, the final result is the same, which will have a serious impact on the valve manufacturing enterprises and the use of enterprises, so it is necessary to attach great importance to this problem and effectively solve it as soon as possible.
1.2 The difference between the inspection situation and the actual use There is such a drawback in the experimental inspection of the valve, because the valve is generally inspected before leaving the factory, and the qualified product will be put into use, but it is not considered to be in actual use conditions. It does not match, so it is often the case that it is qualified in the experimental test, but it does not play a good role in the use process, and there are problems in quality and safety. The valve has a very important standard, that is, the sealing is better, and the environment is not polluted as much as possible. This is closely related to the internal objects and environmental conditions that the valve is to control. Therefore, once the inspection is inconsistent with the actual use, leakage occurs. It is easy to pollute the environment, and even poisoning and explosions, which are extremely harmful to the human body, must be taken seriously.
1.3 The problems that the inspectors have in the experimental inspection of the valve has a major factor affecting its quality, that is, the technical level and comprehensive quality of the inspectors, which is particularly critical, although intelligent inspection methods are currently used, but The basic operation process is still done by someone, so the inspectors are still the key factor. The experimental test methods and technical means of the valve are constantly developing, and the update speed is relatively fast. Therefore, the technical level of the inspectors is very high, and the most advanced methods must be mastered in time, so the inspectors are also required to be very correct in their work attitude. As far as the current situation is concerned, it has not met the expected requirements. There are still some errors in the experimental inspection work caused by some human factors. In fact, this is completely avoidable, so it is necessary to put forward higher requirements for the inspectors.
2. Methods for improving the quality of experimental testing of valves 2.1 Establishing perfect experimental testing standards Perfect experimental testing standards are a key factor in ensuring the quality of valve production. Therefore, it is necessary to solve the problem of the lack of perfect experimental testing standards. Nowadays, many foreign countries have done a lot of work in this area, which is at an advanced level compared with China. Therefore, we can learn from these advanced experiences and combine the actual situation in China to develop a valve test that meets our needs. standard. In addition, combined with the role of valves and the situation of different manufacturing companies, our country also needs to pay attention to it, invest more funds and energy in research, and develop a more uniform and perfect valve test and inspection standards.
2.2 Conducting inspection on the basis of actual use conditions The most effective solution to the drawbacks of the above-mentioned experimental tests of valves is to develop new inspection techniques and methods, and also need to make adjustments in inspection time, except in In addition to the inspection before leaving the factory, detailed laboratory tests should be carried out in conjunction with the use environment before use. This work is actually very complicated, because the valves need more conditions, so the technical means are relatively high, but no matter how complicated, it is necessary for the relevant enterprises to continuously strive to overcome the difficulties encountered. , occupying a place under international competition.
2.3 Improve the ability of all aspects of the inspection personnel In order to ensure the quality of the experimental inspection of the valve, it is necessary to improve the ability of the inspection personnel in all aspects, so the relevant enterprises need to put forward higher requirements when hiring the inspection personnel, not only must master the inspection technology currently used. Means, we also need to pay attention to the latest developments, master the most advanced technical means in time, and apply them to practice. In addition, the comprehensive quality of the inspectors is particularly important, especially the seriousness of the inspection work, because the work is more elaborate and the data requirements are more stringent, so once the mistakes are made, the resulting error will be Very large, so the inspectors need to be serious and responsible. Because this work has a very complex nature, it is necessary to cultivate more excellent talents, avoid the occurrence of human error, maximize the quality of the experimental inspection of the valve, and produce more high-quality valves.
Conclusion Through the detailed introduction of this article, I believe that many people have some understanding of the experimental test of the valve, because the use of the valve is indeed too common, this thing that is closely related to people's production and life needs to be valued because it produces The impact is very large. It is necessary to face up to the actual situation, and to discover and propose the shortcomings in time so that it can be properly solved in the shortest time, and also provide some reference for relevant personnel to carry out research work. This article introduces this part, mainly to achieve such a goal, so that valve manufacturers can continue to move forward.
