Q:Heroes: how to configure the stem with buoys fishing group?
Have not tried, this one I think we should use the appropriate Handshake: Los Angeles pole
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:What's the fishing stem like?
General choice of 2.1 meters or 2.4 meters can be, if the fishing line with 1.8 meters can also, as long as the toughness of the pole enough, with a good point on the wheel.
Q:About butterfly valve plate and valve stem connection
The taper pin is easy to remove and can only be installed in the same direction.
Q:What is the seal between the valve stem and the valve cover?
Apply the molybdenum disulfide grease to rubber parts such as Y rubber ring. It can be sealed
Q:On the butterfly valve, the stem has single axis, no pin and double shaft without pin.
It is generally divided into the upper shaft and the lower shaft. In the assembly process than the single axis slightly harder, if you want to further understand, can add my QQ 51737440, 5, I have here electronic chart, can further understanding.
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: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
Q:Chlorine valve, valve stem, valve spool are selected what material is better?
If it is near the line with a tubular chlorine cylinder interface, small angle valve chlorine national standard, that is the kind of small copper, chlorine bottle valve, pipe line if it is pure chlorine, chlorine has special valve, is a kind of carbon steel valves
Q:Why do the stem and the valve use movable connections?
1., the valve and valve body hole seal, you can customize the center
We have business of various commodities, development of valve parts, brand promotion and agency servicesMain products: valves, mechanical parts, carbon steel, alloy steel parts, castings, forgings, etc. Products are all exported.By virtue of the advantageous location, we have a well-established sales network. We will further widen the market at home and abroad, and provide high quality products and services for our customers.
