- Q: What causes the stem to be stuck?
- The key is the gap between the valve stem and the sleeve, especially when the temperature is too high, easily blocked; it also includes the stem shaft end clearance, valve plate and valve body clearance, valve stem sleeve lubrication, stem wear serious.
- Q: I have a client in Philippines told me that rival the valve plate and the valve stem is connected by bolts, and our products are connected with a taper pin, please tell me the advantages disadvantages of Comrade conical pin connection and bolt connection. Thank you all
- If the bolts were rusted inside, they would not be available unless they were bolted with white steel bolts! Bolt connections will have momentum, and for a long time the bolts may be fatigued and fractured!
- Q: The parts of the valve do not understand
- The drawing rules for some detailed structures in mechanical drawing:When a small plane of an instrument is not adequately represented in a graph, it can be represented by a flat sign (two thin solid lines intersecting).Two visible square planar graph in your local section after the hole is the case.
- Q: Can water wheel be used with valve stem?
- Temporary use, you can, for a long time, not recommended. The guide ring rods and the guide ring number, spinning line has an angle,
- Q: What is the standard for valve stem oiling?
- Often open, high temperature valve suitable for intervals of one week to one month refueling; not often open, the valve is not high temperature, refueling cycle may be longer.
- Q: The smallest diameter of the stem refers to the diameter of the contact portion of the stem packing. The minimum stem diameter refers to the diameter of the stem slot of the valve stem
- This is machining knowledge, you do sales research, this is not easy, huh, huh
- Q: Are there any problems with the horizontal installation of the pneumatic butterfly valve on the horizontal pipe? Is it serious?
- Especially the butterfly valve pneumatic valve is generally installed vertically, horizontally mounted, the stem sealing effect of internal gravity packing layer, resulting in loose packing, the risk of leakage, and the pneumatic valve of the valve positioner will reduce the accuracy of adjusting clearance, cause.In addition, the butterfly valve sealing surface may also be deformed because of the stem deformation and wear.This is the danger, not necessarily be a problem, but the large-diameter valves such as DN150 or more dangerous, if you have a small caliber valve (butterfly valves are generally large, with a small caliber ball valve), will do some suggestions, safety, adjust the installation position.
- Q: Liquefied petroleum gas cylinder angle valve stem leak how to do?
- Beijing reader Wang Zhongtian asked the liquefied petroleum gas bottle corner bar to leak, can the gas bottle continue to use?. Make the following reply. Liquefied petroleum gas cylinders are to be tested for tightness only after they are fitted with a good angle valve. No leakage of any part of the cylinder (including angle valve stem). Because, as long as the leak, will make flammable liquefied petroleum gas diffuse in the room, to a certain concentration, in case of fire, will be burning explosion.
- Q: here's "first half week" refers to what?
- For example, fire pump, water pipe, gate valve, to see this side to the horizontal 90 degrees, turn 90 degrees in the opposite direction
- 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.
