Reasons For Regularly Checking The Liquid Level Height Of The Sanitary Butterfly Valve Tank
Reasons for regularly checking the height of the Sanitary Butterfly Valve oil tank
Under normal working conditions of sanitary valves, the oil level needs to be above 1/2 of the height level. If it is less than 1/3 of the height level, it must be refueled. With "low level" control and protection, the oil source system will stop working if the liquid level is too low. The sanitary valve and preparation method are suitable for various process products until a scale is required and the system will restart.
First, the accumulator gas pressure should be checked regularly (one month). If the health level is lower than the inflation pressure of the butterfly valve specification, 10% nitrogen should be added, and the nitrogen pressure reaches the specification pressure. After half a year, review the gas pressure in the accumulator once a quarter.
During the production operation of the health level package butterfly valve hydraulic drive, attention should be paid to the change of oil conditions, and regular (quarterly) sampling tests should be conducted. The form of stainless steel sanitary fittings and a closed rotary valve are used as the surrounding. If you find that the oil does not meet the requirements, purify or replace it with new oil in time, and the oil pollution level system should be kept above NAS8.
Does the arrow of the sanitary butterfly valve indicate the direction of the medium or the direction of pressure?
Generally, it is the flow direction of the medium. If it is the direction of pressure, the manual should be specially marked. The arrow on the butterfly valve is usually the direction of medium flow.
If this direction is reversed, does it have little impact? A pneumatic butterfly valve in my device was installed in the opposite direction, but it did not have much impact in actual operation.
The arrow on the sanitary butterfly valve should be the direction of medium flow. The direction of medium flow has nothing to do with the pressure
When the butterfly valve is installed normally, if there is no arrow direction on the valve body, it can be installed easily, but if there is an arrow, it should be installed in the direction of the arrow, and the three-eccentric valve must be installed in the same direction as the arrow on the valve.
The arrows on the used valves are all in the direction of medium flow. Butterfly valves are generally not marked for symmetrical ones; eccentric ones should be installed according to the arrows.
