SMC valve maintenance 13 big trick magnetic flip plate level gauge flange and valve fault solutions

SMC valve maintenance 13 tips
1. The storage environment of the valve should be paid attention to. It should be stored in a dry and ventilated room, and both ends of the pathway should be blocked.
2, the valve should be regularly checked, and *** the dirt on it, smear rust oil on its surface.
3. After the installation and application of the valve, it should be regularly inspected to ensure its normal work.
4. Check whether the sealing surface of the valve is worn, and repair or replace it according to the situation.
5. Check the trapezoidal thread wear of the stem and stem nut, whether the packing is outdated and invalid, and carry out the necessary replacement.
6. Test the sealing performance of the valve to ensure its performance.
7, the operation of the valve should be intact, flange and bracket bolts complete, thread damage, no loose phenomenon.
8. If the hand wheel is lost, it should be assembled in time, and can not be replaced by a live wrench.
9, packing gland is not allowed to skew or no preload gap.
10. If the valve is used in a harsh environment, susceptible to rain, snow, dust, sand and other dirt, it should be installed for the valve stem protective cover.
11, the ruler on the valve should be kept complete, accurate, clear, valve seal, cap.
12, thermal insulation jacket should be no sag, crack.
13, in operation of the valve, avoid beating it, or support heavy objects.
The people in the industry agree that it is a reliable and safe detection instrument, the main reason is that the magnetic flip level meter with magnetic coupling isolation and closed structure is especially suitable for flammable, explosive and corrosive toxic liquid level detection. So that the original complex environment liquid level detection means become simple and reliable and safe. The INSTRUMENT IS SUITABLE FOR MEASURING THE LIQUID LEVEL OF ALL KINDS OF PRESSURE (or open) LIQUID STORAGE EQUIPMENT (tower, cylinder, tank, spherical vessel and boiler) IN the process of industrial production.
Because of the unique characteristics and performance of the magnetic flip plate level gauge, industry insiders agree that it is a reliable and safe detection instrument, the main reason is that the magnetic flip plate level gauge has a magnetic coupling isolation closed structure. Especially suitable for flammable, explosive and corrosive toxic liquid level detection. So that the original complex environment liquid level detection means become simple and reliable and safe. The INSTRUMENT IS SUITABLE FOR MEASURING THE LIQUID LEVEL OF ALL KINDS OF PRESSURE (or open) LIQUID STORAGE EQUIPMENT (tower, cylinder, tank, spherical vessel and boiler) IN the process of industrial production. It can display the working condition and liquid level height of various liquids on the spot. With liquid level transmitter can be transmitted over a long distance on the surface of the liquid position signal, through certain electrical device to achieve the purpose of automatic control and measure the liquid level, for different measurement conditions and requirements, installing a magnetic flap level gauge can be adapted by supporting the installation components, which can be * * to enhance magnetic flap liquid level meter in the adaptability of the measurement.
Flange valve is an important structural component of magnetic plate level gauge, in the long-term use of the process, flange valve will produce a variety of faults, but also need to carry out regular maintenance and cleaning. This article is a brief introduction when the user in the encounter of magnetic plate level gauge flange valve failure how to solve various methods.
I. Leakage of sealing surface:
1, magnetic flip plate level gauge flange sealing surface is attached with dirt. Solution: Clean the sealing surface.
2. The sealing surface is damaged. Solution: Grind or replace the sealing surface.
Two, the stem transfer is not flexible:
1, spool cover Angle is too tight or bearing wear. Solution: adjust the packing tightness or replace the bearing.
2, there is debris or dust between the stem or stem nut, stem or stem nut damage. Solution: Disassemble and clean the stem. If damaged, replace the stem or stem nut.
3. The opening and closing device is faulty. Solution: Check the fault according to the device instructions and repair it
Three, the middle magnetic plate level gauge flange leakage causes and solutions:
1. Flange connection bolts are not tightened or the tightness is uneven. Solution: Loosen the screw and then tighten it evenly and symmetrically.
2. Gasket damage or failure. Solution: Replace the gasket.
3. There is dirt between the sealing face of flange. Solution: Remove the cleaning flange.
Four, stuffing box leakage:
1, packing loose or packing gland pressure deviation. Solution: the packing gland should be evenly pressed.
2. Flange packing of magnetic flip plate level gauge fails. Solution: Replace the filler.
