Valve maintenance of common problems in maintenance and matters needing attention

Daily valve maintenance

1, the valve should be kept dry and ventilated room, access to be blocked at both ends.

2, the long-term storage of the valve should be checked regularly, remove the dirt, and in the processing of surface coated with anti rust oil.

NSF Approval Volumetric Piston Brass Remote Reading Gallon Water Meter

3, after installation, should be regularly checked, the main inspection items:

(1) sealing surface wear.

(2) the trapezoidal thread wear stem and stem nut.

(3) packing is outdated, should be replaced if damaged.

(4) the valve repair assembly, the sealing performance test should be carried out.

The NSF Approval Volumetric Piston Brass Remote Reading Gallon Water Meter greasing maintenance work

Before the welding operation of the valve before and after commissioning professional conservation work, as the valve manufacturing operations in the service plays a vital role, correct and orderly and effective maintenance will protect the valve, the valve function and prolong the service life of the valve. Valve maintenance work may seem simple, but in fact it is not. Work often neglected aspects.

First, the valve grease, often overlooked issue of the amount of grease. Grease gun refueling, the operator select valves and grease coupling method, the grease job. There are two kinds of situations: on the one hand, less fat less grease, sealing surface accelerated wear due to lack of lubricant. On the other hand, excessive grease, resulting in a waste of. That there is no according to valve type category, the sealing capacity of different valves accurately calculated. Can be calculated valve size and type of seal capacity, and then injected into a reasonable amount of grease.

Second, the valve grease, often ignore the problem of stress. Operation in the grease, the grease pressure peak and valley was changed regularly. The pressure is too low, the seal leakage or failure, the pressure is too high, the injection port congestion, sealed within the lipid hardening or sealing ring and the valve ball, valve plate locking. Usually grease injection pressure is too low, grease into the valve chamber over the bottom, generally occurs in a small gate. While the grease injection pressure is too high, on the one hand to check the grease nozzle, such as pore blocking fat replacement to identify the situation; on the other hand the lipid hardening, to use the cleaning fluid, repeatedly soften the failure of sealing grease, and inject new grease replacement. In addition, the seal type and sealing materials, also affected the grease seal pressure, different forms have different grease injection pressure, in general hard sealing grease injection pressure is higher than the soft seal.

Third, the valve grease, pay attention to the valve in the switch position problem. Maintenance when the ball valve in the open spaces in general, special circumstances to choose to close the maintenance. Other valves can not be punished in order to open spaces. When the valve in the conservation must be closed, to ensure that the grease seal along the trenches filled with ring, if the open position, sealing grease flow directly into the cavity or valve, resulting in a waste of.

Fourth, the valve grease, the grease effect often ignore the problem. Injection pressure, fat operation amount of grease, the switch position are normal. But to ensure that the valve greasing effect, and sometimes need to open or close the valve, lubricating effect on the inspection, confirmed that the ball valve or gate surface lubrication uniform.

Fifth, the grease, should pay attention to body and plug the pressure relief discharge problem. Pressure test valve, gas valve chamber sealed chamber and the water temperature rises due to step-up, when to conduct the sewage grease relief, in order to facilitate the smooth progress of the work the grease. The grease seal cavity of the air and water are full replacement out. Timely release the pressure valve cavity, but also guarantee the safe use of the valve. After greasing, be sure to tighten the wire blocking the sewage and pressure relief, to prevent the accident.

Sixth, the grease, we should pay attention to the issue of fat evenly. Normal grease, the grease away from the port hole nearest the fat out of fat first, then to low, and finally the high point, successive fat. If not by law or not fat, prove the existence of congestion, Qingtong processing.

Seventh, the grease should be observed when the size of valve and seat ring flush problem. Such as ball valve, open spaces if there is interference, can be adjusted to the Volumetric Piston Plastic Remote Reading Gallon Water Meter with NSF Approval, after the lock confirmation straight path. Adjust the limit not only the pursuit of a party on or off position, to consider the overall. If the open position flush, customs are not in place, will cause the valve loose. Similarly, adjusting the relations in place, also want to consider to open a corresponding adjustment. Ensure that the right angle valve travel.

Eighth, the grease, the grease must seal the mouth. To avoid impurities, fat mouth or injection of lipid oxidation, rust proof seal to apply grease, avoid rust. Applications for the next operation.
