Our goal: to be a high-quality manufacturer of industrial control valves, gaining unanimous recognition from new and old customers
Our mission: To fully utilize the effectiveness of industrial control valves to achieve better results
1. Different processes
To some extent, imported valve products are indeed slightly superior to domestic ones.
The management philosophy of the foreign valve industry is also very different from ours. They pursue quality rather than quantity. Some of our industry leaders and experts have visited abroad and found that the quality and management of foreign valve products are indeed impeccable, their processing equipment is good, their research and development level is good, and the products manufactured with good materials and equipment are definitely the same. This has created excellent quality of foreign valve products.
It is understood that the main reason for the excellence of foreign valves is that their processing technology is different from ours, which has formed the excellent quality of their own products. For example, in order to meet the radiation resistance requirements of sealing materials for nuclear grade valves, German KSB company has widely used special welding powder for cobalt free welding in the welding process. The method is to sinter the welding powder and conduct post weld heat treatment. Valve products are designed according to the requirements of operating conditions. High temperature and high pressure gate valves mostly adopt parallel double gate structures.
Example analysis
French Valve Company Weilan completes pre welding preheating, automatic welding, and post welding treatment in the same equipment or on the same processing and production line. Regardless of pre welding, during welding, and post welding treatment, temperature can be automatically controlled, ensuring welding quality, simplifying welding processes, and improving welding efficiency. Especially for relatively complex welds (such as automatic welding for straight and curve connections), automatic welding is achieved.
2. Complete control means
The quality of foreign valves is also closely related to their strengthening of quality management and equipment management. It is understood that the quality of foreign valve products can generally meet the requirements of API, JIS, BS, and other standards, and the inherent quality and accuracy of casting blanks are high. Their blanks can be processed on a special machine without repair, with beautiful appearance, clear handwriting on the cast trademark, good sealing performance, and a variety of specifications of fillers and gaskets, It can meet the requirements of different working conditions.
The performance parameters of the automatic control valve are stable, fully ensuring no leakage in use, and accurate adjustment accuracy. The service life of general-purpose valves can reach 1-2 maintenance periods, or even longer.
As foreign valve companies have complete quality control measures, complete hot and cold test equipment, and use coordinate measuring instruments and various flaw detection equipment to strictly inspect to ensure that the quality of each link is in place. Each part is clear at a glance in any process, with very detailed records, clear responsibilities, and good surface quality, including forging quality, surface polishing, and weld quality, almost eliminating bumps and scratches, Thereby ensuring the excellent performance of foreign valve products.
Example analysis
For example, Bernard Electric Equipment Company of France had a sales volume of 300 million yuan in 2005, with exports accounting for 70% of the sales. It has established a global sales network, and a large number of its electric equipment products are used in metallurgy and oil and gas pipelines in China. In the field of nuclear power, their supply ranks second in the world.
It is said that in China's Qinshan Phase II, Daya Bay, and Tianwan nuclear power plants, 80% of the nuclear equipment is also supplied by them, and their management is in place. The company's parts processing records are circulated with the parts, the production site is neat and tidy, and the two assembly lines are working in an orderly manner. Their screw rod processing adopts a rolling method with high efficiency, high surface finish of the parts, timely cleaning and treatment of the processed parts, and proper application of station equipment. For example, covering each shaft with a plastic bag is very simple, but very practical, avoiding collisions and scratches between parts. The painting method for parts is similar to that in China, but due to the smoothness and smoothness of the blank itself and the excellent quality of the paint, the appearance effect and quality of the painted product are quite good.
3. Process
Almost all product components are completed on CNC equipment, with high machining accuracy and efficiency. Employees can access part processing drawings and parts processing procedures on the operating platform of the CNC processing equipment. They only need to clamp the workpiece onto the CNC equipment according to the processing process requirements, start the processing program, and can automatically complete machining processes such as turning, drilling, milling, and boring. After the processing program of one device is started, proceed to clamp the other device. At the same time, the processing status of other devices can be monitored on the device operation screen until the entire part is processed and sent to the assembly workshop after passing the inspection.
After each part is processed, the employee swipes the part tracking card on a card reader nearby, and feeds back the status and processing information of the part to the relevant departments, so that the relevant departments can grasp the processing progress, count the workload of workers, and track quality. It also has very complete testing equipment that can perform high-precision three-dimensional dimensional testing, as well as dynamic balance tests, high and low temperature tests. Their warehouse management is very strict, and three-dimensional computer management is implemented. The warehouse management personnel only need to input production instructions and quantities into the computer. The system will automatically take the required components from the shelves, then classify them for packaging, and send them to the assembly workshop. In this way, the quality of the product processed carefully according to the process procedures will definitely reach the standard.
Foreign valve products are highly clean and well treated, and each process strictly complies with standards, including civilized production in the workshop and environmental hygiene. Dust prevention, rust prevention, burr removal, polishing, and cleaning of product parts, as well as cleaning and drying before assembly, are all in place without leaving any trace. Employees are also conscientious and meticulous.
Example analysis
It is understood that the characteristics of the production process of Nuovo Pignone in Italy are: after receiving an order, the design and development center transforms it, provides technical documents such as product design drawings, outsourcing and purchasing details, and machining procedures, and transmits them to relevant departments through the internal network. The production department organizes production according to technical requirements and sales orders.
After the blank parts enter the factory, the warehouse keeper will send the blank parts and other stages to various processing and assembly sites according to the production plan. They do not all produce them themselves, but many also purchase them.
