Q:How to adjust the valve stem valve leakage?: The valve leakage is 1, the spool and the valve seat sealing surface wear, grinding or replacement; 2, 3, the stem is too short; there is a foreign body card in

Q:What is the seal between the valve stem and the valve cover?: Most valves:The seal between the valve and valve cover depends on the valve cover gasket.The seal between the valve and the stem depends on the packing.There are also valves, valves and stem seal between bellows, "O" ring, and so on.

Q:What is the standard for valve stem oiling?: Some parts of special cup with oil or grease, if damaged or lost in the operation, should be installed for repair, oil to dredge. Lubrication parts shall be regularly lubricated according to specific conditions.

Q:Ball valve stem 90 degrees milling flat, how to process?: Vertical milling or horizontal milling can be as good as vertical milling.One is clamped with the index head, and the other can be milled with the top. (graduated with a scale)

Q:Can the stem and sphere of a ball valve be made into a whole? Did you do that? Seek specific analysis: Top mounted ball valve. The stem is joined to the sphere.

Q:Stem material: 5, bearing steelSelection of GCr15, applicable to the nominal pressure is less than 300MPa, the temperature is less than or equal to 300 degrees of ultra-high pressure valve.Used to make the stem more materials, as well as 4Cr10Si2Mo martensitic heat-resistant steel, 4Cr14Ni14W2Mo austenitic heat-resistant steel.The stem nut and the valve stem match with the screw thread, and directly bear the axial force of the valve stem, and the friction between the plate and the support valve. Therefore, the stem nut in addition to a certain strength, but also requires a small friction coefficient, not rust, and stem does not bite and other performance.

Q:then stem is how to fit inside the valve body? The outside diameter of the valve stem is larger than the bore diameter: The stem is put in from the middle. You can put it in a bit diagonally

Q:Hello, the valve material is 3Gr13, stem 3Gr12, I would like to ask, this valve against sulfur?: it is easy to be corroded, the best use of dual phase steel, 20 alloy steel, alloy steel and zirconium C276 wood, but also to see the specific medium containing exactly what, these materials should be the cheapest dual phase steel

Q:What is the difference between the upper valve stem bearings of the thrust bearings?: Its force direction is not the same, the general bearings are radial force, and the thrust bearing is in the end direction of the force, the solid structure is not the same."And you ask" thrust bearings, upper stem bearings what is the difference? / / thrust bearing, stem bearing difference"

Q:The lift valve is not a single stem, but the stem and the screw are connected by the semicircle clasp. The screw rises and drives the stem to move up and down 30Want to ask why this structure instead of a whole stem, what benefits, the other is to check on the stem general calibration will stem and screw as a whole or a single check to check valve stem? Some people even say that stiffness does not need to be checked for stability: I see what you mean. There's a packing ring between the stem and the screw, and there's a filling in the circlip.
