Shanghai Wuyue safety valve company solved the abnormal problem of safety valve for Sinopec Taizhou on April 10, Shanghai Wuyue XCMG and the manager of marketing department drove to Taizhou, Jiangsu Province. Half a month ago, the sales department received a request from Sinopec oil depot in Taizhou. The oil depot purchased a batch of parallel safety valves from Shanghai Wuyue in March last year. Unfortunately, it was only this year that the full return valves were officially installed on the pipeline equipment of the oil depot. However, it was found that on April 10, XCMG Shanghai Wuyue and the manager of the marketing department drove to Taizhou, Jiangsu Province. Half a month ago, the sales department received a request from Sinopec oil depot in Taizhou. The oil depot purchased a batch of parallel safety return valves from Wuyue, Shanghai last March, and formally installed them on the pipeline equipment of the oil depot this year. However, it was found that the safety valves always took off. Through negotiation between the two sides, it turned out that the design institute originally set the working pressure of the oil pump pipeline at 0.35Mpa, However, the safety valve failed to pass the test. The designed opening pressure is also 0.35Mpa. It is obvious that the pressure in the pipeline has been equal to or exceeded the set pressure of the safety valve, and the safety valve will naturally open continuously

however, this problem involves three parties: the first is the Design Institute, the second is the equipment procurement and installation party, and the third is the manufacturer. The design institute has always denied that there is a problem with the pressure design, and the equipment procurement and installation party can only repeatedly request the manufacturer, Shanghai Wuyue safety valve company, to send someone to negotiate, hoping that the three parties can work together to build an annual output of 100000 tons of aluminum profiles, spraying, electrophoresis and aluminum alloy new material processing project to solve the problem

after arriving at the site, XCMG Shanghai Wuyue found that the people from the design institute had not come at all. At this time, the pressure gauge on the lower pipeline showed 0.25MPa, and the safety valve did not jump. Director Zuo, the person in charge of the oil depot, said that since there are not many oil loading vehicles, the pressure will rise with the increasing output of the oil circuit; The high temperature will also affect the pressure rise in the pipeline. When the person in charge of the oil depot and the equipment procurement and installation party were on site, Shanghai Wuyue XCMG patiently explained to them again that the frequent jump of the safety valve could not be attributed to the fact that the quality of the safety valve still has a large market space for the development of the extruder industry. The normal working pressure range in the pipeline itself is equal to or exceeds the design setting pressure of the safety valve, unless the setting pressure of the safety valve is adjusted higher, However, there is no significance to install the safety valve in this way. It is better to remove the safety valve directly. Finally, the oil depot and the equipment installer agreed to dismantle the safety valve and temporarily connect it with a straight pipe, waiting for the design institute to give a new design scheme
