Q:Replace gate valve stem packing
First use the packing tool to hook out, and then in the shaft measurement, and then put it inside the installation, or simple point to tell me the working conditions, I suggest you use what kind of simple stem sealing packing
Q:What is the function of the stem nut? My valve can not be opened, is it because you want to loosen the rod nut to move?
Positioning effectPerform device link with valve stem
Q:What are their respective advantages and disadvantages?
Valve advantages:1, small flow resistance. Inside the valve body, the medium passage is straight through, the medium flows in a straight line, and the flow resistance is small.2, when opening and closing more effort. In comparison with the cut-off valve, the gate movement direction is perpendicular to the direction of the flow of the medium whether it is open or closed.3, high height, long opening and closing time. The opening and closing stroke of the ram is larger, and the reduction is done by screw.4, the media can flow in any direction on both sides, easy to install. Gate valves are symmetrical on both sides of the channel.5. Compact structure, good rigidity of valve, smooth channel, small flow resistance, stainless steel and carbide alloy used in sealing surface, long service life, PTFE packing, reliable sealing, easy and flexible operation
Q:How is the sphere of the Solidworks ball valve fitted with the stem or valve body or valve seat?
However, it should be noted that, first of all, adjust their position almost, so that the valve has generally been in the valve body, in order to match success.
Q:The ball valve in the valve is in what state is open
The switch of the ball valve is 90 degrees angle (except the three pass) and the slot is limited.
Q:What is the standard for valve stem oiling?
Valve trapezoidal thread, the stem nut and the bracket sliding parts, gear parts part of bearing, gear and worm gear, worm and other sites with activities, are in need of better lubrication and reduce friction between each other, to avoid wear and tear each other.
Q:What exactly is the stem nut, please
Sometimes it is not possible to use copper alloy stem nuts for production and operation. Because some products or environment will corrode copper medium, the material of the stem nut can not be made of copper. On the basis of the electric valve, the stem nut has a melon clutch, which requires a certain amount of heat treatment to achieve more surface hardness and maximum hardness. When using the steel stem nut, we should pay attention to the thread, and the steel stem nut is easy to bite. But the stem nut is only suitable for low pressure and small bore valves. The strength of the stem nut of this material is less than that of the metal stem nut
Q:Sea poles, stem what is the difference between the general water reservoir play, 3 meters or so, what pole is better, please advise
The sea rod called cast rod or pole. It has a winding wheel at the handle of the fishing rod. It is covered with fishing lines, so that when it is thrown, it can throw the bait hook into the far water and throw it very far away.
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:It seems to be used on the stem nut. Yes, thank you. Ah, thank you
It is mounted behind the seat and plays a key role in the thrust and closure of the valve seat.
