Q:What are the specialized equipment for producing valve stem?
CNC CNC lathe, CNC milling machine, CNC milling machine is now the fastest can be in place. This part of Wenzhou is called a flying (milling) stem,Gate valve, globe valve and other T thread are CNC milling machine flying, professional processing valve stem is doing so
Q:The role of valve stem in process gate valve
At the same time, it is subjected to the impact and corrosion of the medium, and it also causes friction with the packing.
Q:Shandong 30 loader multiple valve stem card what's wrong.
You take the two main stem carefully removed, check the stem and valve bore cavity whether there is scratch, if there is a local scratch, it may be dirty stuck in it, and then pull the stem when it pulled. Scratches if deep, leakage will be large, repair will feel bucket slow, little force and so on. All components should be removed before washing, especially the safety valve. After the demolition, the whole body with kerosene cleaning, safety valve pressure should not be adjusted, or there is no test stand, you do not know the specific pressure is how big.
Q:What is the appearance of the valve with no stem valve?
1, according to the classificationThe role of the (1) cut-off valve and purpose: stop valve, also known as closed valve, whose role is to connect or disconnect the line media. Globe valves include gate valves, globe valves, plug valves, ball valves, butterfly valves, and diaphragm valves.(2) check: check valve, also known as one-way valve or check valve, its role is to prevent the medium back of the pipeline. Pump water off the valve check valve also belongs to the class.(3) safety valve: in the role of the class is to prevent the pipeline safety valve or device in the medium pressure exceeds the specified value, so as to achieve the purpose of safety.Peso (4) control valve: valves include regulating valves, throttle and relief valve, the role is to regulate the media pressure, flow and other parameters.Pesos (5) shunt valve: diverter valve, including a variety of distribution valves and traps, etc., the role is to distribute, separation or mixed media lines.
Q:Pipeline ball valve in the valve stem generally choose what material?
Generally, there are the following choices: AISI 4140, A182, F6a, 17-4PH, A182, F316, A182 304, AISI 1040, ENP
Q:Halleluyah fishing method with the stem line?
Also can, is not suitable for fishing for large ferocious fish, adverse control of fish, throwing bids is not good point
Q:The stem is suitable for what kind of fishing
General raft rod length of 1.6 meters to 2.4 meters long, the color section before the shoot distribution of bright colors and more conducive to the observation of the fish, rod shoots for glass fiber rod solid rod, a very soft and elastic, a little external force can be clearly reflected, rod slightly small and dense distribution.
Q:How to set the valve stem diameter
Check the standard, there will be the corresponding pressure, diameter of the smallest diameter of the stem, such as gate valve is GB/T12234-2005, sorry ah, I do not have information on the ball valve, you go to check
Q:What is the connection between the stem and the gate of the low-pressure gate valve?
That's what I told you last time, the screw and the mother wire connection, the two threads bite each other.
Q:What is the reason that the valve stem can not be rotated in the water supply pipe?
Shut off for too long too much death will not open in the first.Just move it will be all right
