Daily maintenance of the valve 1, the valve should be kept dry and ventilated indoor, access blocked at both ends. 2, long-term storage of Hongfeng valve should be regularly checked to remove dirt, and coated with anti-rust oil on the processing surface. 3, after installation, should be regularly checked, the main inspection items: (1) sealing surface wear and tear. (2) trapezoidal stem and stem nut thread wear. (3) whether the filler is out of date failure, if damaged should be promptly replaced. (4) Hongfeng valve repair assembly, the sealing performance test should be carried out. Valve grease when the maintenance work Before the welding put into operation and put into operation after the professional valve maintenance work for the valve in the production and operation plays a crucial role in the correct and orderly effective maintenance will protect the valve so that The valve functions normally and extends the service life of the valve. Valve maintenance work seems simple, it is not. Often overlooked aspects of work. First, the valve fat, often overlook the problem of fat volume. After the grease gun, the operator chooses the valve and grease coupling method, the grease injection operation. There are two situations: on the one hand less fat less lipid injection, sealing surface due to the lack of lubricant to speed up wear and tear. On the other hand excessive fat, resulting in waste. There is no exact calculation of the different valve seal capacities based on the type of valve. The valve size and type can be calculated seal capacity, and then a reasonable amount of grease into the appropriate. Second, the valve fat, often ignore the pressure problem. In the grease injection operation, lipid injection pressure showed a regular change in the peak valley. Pressure is too low, the seal leak or failure pressure is too high, the injection port blocked, seal the lipid hardened or ring and valve ball, valve plate lock. Usually grease injection pressure is too low, more grease into the valve cavity flow at the bottom, usually occurs in the small gate valve. The grease injection pressure is too high, on the one hand check the grease nozzle, if the obstruction of the case identified to be replaced; on the other hand, lipid sclerosis, to use cleaning fluid, repeated softening failure of sealant, and injected new grease replacement . In addition, the sealing model and sealing material, but also affect the injection pressure, different sealing forms have different injection pressure, the general situation of hard sealing grease pressure is higher than the soft seal.
