Q:Automatic exhaust valve installed in the pipe before and after the installation of other valves need to press it?
In general, the exhaust valve (large diameter) and a maintenance valve, normally open,
Q:Valve installation
It looks a bit like the butt weld butterfly valve. The two sides are welded to the pipe. There is a step on either side of the valve. Overhead welding
Q:Which valve can play a good regulatory role?
A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.
Q:What does 3/4''mean in the name of the valve?
Valve diameter, that is, we often say 6 points valve, used in English units, with metric units should be DN20.2 points DN84 points DN156 points DN20 (3/4'')1 inches DN251.2 'DN321.5 'DN402 'DN502.5 'DN653 'DN804 'DN1005 'DN1256 'DN1508 'DN20010 'DN25012 'DN300Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.Because the units have metric (mm) and British (inch) distinction, there are the following methods of address.1., based on the metric system (mm), called DN (metric unit)2., on the basis of the British system (inch), called NB (inch unit)DN (nominal, diameter)NB (nominal, bore)OD (outside, diameter)
Q:How to use current to control valve opening and closing?
A relay or PID controller can achieve this operation, only need to set out, the valve can use electromagnetic valve, which belongs to a rapid opening and closing valves, only need to control the electric power to the valve can automatically open or closed, but the temperature change is large, if you want to keep the temperature constant. The best selection of regulating valve, constant temperature control valve will be before or after the valve, the main electrical control knowledge, do not know what I said is clear, remember the points, thank you!
Q:What does valve DN50/80 mean?
DN refers to the nominal diameter unit mm, that is, the diameter of the pipe. DN 5080 is the diameter of 50mm 80mm
Q:Where is the hydrant main valve?
The intake valve of the upper and lower ring pipes of the riser of the fire hydrant is generally located at the highest and lowest floors.The general use of the valve rod flange gate valve.Hydrants, officially called fire hydrants, are a type of fixed fire fighting facilities, which control fuel, insulate fire and eliminate fire. Indoor fire hydrant and outdoor hydrant. The fire fighting system includes outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some automatic sprinkler system, water gun system, gas fire extinguishing system, fire detection system, water mist system and so on. Fire hydrant mainly for fire engines from the municipal water supply network or outdoor fire water network to implement fire fighting, can also be directly connected to the hose, water gun fire extinguishing. Therefore, indoor and outdoor fire hydrant system is also one of the important fire fighting facilities.
Q:What are the general types of valves?
There are generally 3 types of ball valve, globe valve, ceramic core valve
Q:What is a lift rod valve?
The valve stem and valve plate are relatively fixed, and the valve stem rises up when the valve plate is raised
Q:Where is the filling portion of the valve?
The middle of the screw down valve handwheel saw packing gland generally about two screws fixed or fixed on the pressure cap down is the appearance of the packing is not seen inside if leakage occurs usually filler filler fastening screws, general pressure valves are graphite filler
We have advanced technologies, facilities, resources and talented personnel for processing, developing, studying, designing and manufacturing of different kinds of valves. Our main products are wafer and lug type butterfly valves, slim pinless butterfly valves, flanged valves, gate valves, check valves, ball valves, and Y-strainers in medium and low pressure rate. Our valves are widely applied to water draining, power generation, petroleum, chemical industry, heat supply, metallurgy, medicine, and grocery, as the throttling and shutting-off equipment.
