Q:Can stem fishing snakehead? Do you have to use Lei Qiang to catch it? Ask for advice
Let's see! After the craft has learned, the graph is refined, the text comes up ha!
Q:What are the connecting ways of valve plate and valve stem of gate valve?
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:Halleluyah fishing method with the stem line?
Or choose the special road pole better, "work to good things, must first benefit its device" well!
Q:Stem deformation of valve stem
So why would the stem fracture or deformation of a few points: normal temperature and pressure of the valve body cavity there is closed, that is closed in the valve, the fluid pressure in the cavity closed at the upstream and downstream sides between the sealing surface is far higher than the upstream pressure.
Q:River fishing rod or sea pole?
Sea rods are good stem valve rod head to buy hard to buy sea pole soft lead is generally 50 to 150 ha, I also listen to them.
Q:How to use a dial indicator measuring stem bending
1) when measuring, both ends of the journal are supported on the ball bearing, and the thrust of the shaft should be limited to 0.10mm within the range of measurement.(2) the equal axis along the length direction measurement, measurement point selection in the surface must be free of burrs, pitting, bulge, smooth pit shaft.
Q:DN>=50 valves use grease lubricated bearings between the stem and the support
All need dust protection measures, long time, in order to prevent the garbage things adhesion
Q:What is the cause of valve stem vibration in electric single seat control valves?
3, liquid medium through the valve, resulting in cavitation caused by shocks, higher frequency, usually accompanied by valve howling. High temperature large pressure difference, the use of single seat valve is relatively easy to happen, this is the control valve (valve body structure) type selection caused by improper,4, the valve core resonant frequency and pipe and fluid frequency consistent with the vibration caused by higher frequency, usually accompanied by pipe vibration. Change the valve at both ends of the process, valve opening may be eliminated.
Q:What is the reason for the leaking of the stem of the open rod gate valve? How to solve?
Perhaps the spool is broken, you go to the building materials market to buy a spool of the same type, you ask the merchant, they know what to give you.After returning home, turn the old spool off and change itIf you do not sell the spool alone, you buy a complete valve, back to the spool down, on the line.If it is that kind of pure plastic valve, then I'm sorry, I can only see the pipe and change the valve.
Q:How to set the valve stem diameter
You can refer to the size of the sleeve of the pneumatic actuator which is matched with the ball valve
