Recommended enterprise: Ruituo Valve Maintenance Co., Ltd.
The most important thing in valve maintenance business is quality assurance.
in fact, the service life of the valve body is between 12 and 3 years, and the main damage of the valve is the sealing surface. How to maintain the sealing surface becomes the key to the feasibility of valve maintenance.
in the steps of valve maintenance, the first step is to communicate well with the customer units, and mark the production key of each replaced valve, so as to choose the most appropriate maintenance scheme, especially the surfacing welding of the sealing surface of the valve body and the valve core with stainless steel covered electrode or cemented carbide covered electrode.
finish machining is carried out on the sealing surface after surfacing welding. Small-caliber valves can be machined by lathes and tooling, while the machining of large-caliber valves is difficult.
All the valve grinders in the market can't finish the sealing surface after surfacing, but can only repair the abrasion on the raw materials, which will do great damage to the valve
and can't guarantee the repair of the sealing surface.
At the end of p>21, after 9 years of research and development, Ruituo Valve Maintenance Company produced a "vertical valve maintenance grinding machine tool" integrating grinding and precision grinding, which can perfectly solve the grinding and grinding problems of large-caliber
valves after surfacing welding on the sealing surface.
Especially in the valve remanufacturing repair of "hard-sealed ball valve", which is a difficult problem in valve maintenance in the world, the ball grinding and precision grinding equipment developed by Ruituo Valve Maintenance Company has solved
the repair problem of hard-sealed ball valve, and the ball that has lost its ball body and been washed and worn is subjected to precision grinding after stainless steel spray welding or repair welding, and the ball valve body is subjected to
precision machining, which can completely restore the fit of hard-sealed ball valve.
Ruituo Valve Maintenance Co., Ltd. can set up a perfect valve maintenance and renovation system for each customer, from the combination of lathe configuration, tooling research and development, valve grinding machine tools, to the establishment of valve maintenance inspection
acceptance standards, etc., from receiving the old valve to completing the valve repair and returning to the production line, the quality is tracked and controlled throughout the whole process, and the repaired valve reaches and exceeds the number of times and years of use of the new valve, and can be repeatedly repaired, saving a lot of procurement expenses for enterprises.
