Q:I would like to ask how to access the valve?
May learn some basic knowledge of valves, learning in practice, relatively fast.
Q:Is there any difference between the valve and the water valve?
There is no difference between the low pressure lubricating oil pump, as long as the excuse right on the line, not to pressure, design pressure ball valve common does not exceed 3MP, the maximum pressure of only small gear pump vane pump is 2.5MP, the other piston pump, gear pump, the pressure is above 6.3MP. Certainly not. Unless using high pressure water pipe valve.
Q:Is the valve galvanized?
If you need it, you can order it. Any valve will do
Q:What does "1/2" mean on the valve?
1/2 is 4 points (20), 3/4 is 6 points (25), and 1 is 1 inches (32)
Q:What's the valve specification DN20?
It's not clear what you want to ask
Q:How to open the gas valve?
First of all, you have to determine the direction of the valve opening, usually homeopathy, it is off, the reverse is open. First: to determine the opening of the valve, are generally ball valve, screw 90 degrees on it. Second. At the top of your house, there is a button that can be pulled out. It's different from place to place. Some are pulled out half, and some are pulled out. Third: in the following there is a black disk like thing, commonly known as the gas sound core. This is the same as the second, pull out half or all, so that you can use gas, ha ha!
Q:What does valve A335P22 mean?
May be non-standard label bar, do not understand, A3 should refer to the body, the material is 13Cr.
Q:What is the valve before and after the pump?
General pump should be installed before and after the pressure regulating valve, pump installed before the pressure drop valve, pump installed after the pressure regulator valve!
Q:How to better maintain the valve?
How to maintain the valve?Enter the same as other mechanical products, but also the need for maintenance. This work well, can extend the service life of the valve, the following will introduce the valve maintenanceStorage and maintenanceThe maintenance of the purpose is to keep the valve in the custody of the damage, or lower quality. In fact, improper storage is one of the important reasons for valve damageThe valve custody, should be arranged in good order, a small valve on the shelves, large valves can be neatly arranged in the warehouse on the ground, not arbitrary lumber pile, do not let the flange face contact with the ground. This is not only for beauty, mainly to protect the valve, not to touch badBecause the storage and handling properly, hand wheel broken, crooked stem touch the fixed nut hand wheel and stem loosening loss and so on, these should avoid unnecessary losses.We temporarily on the short-term use of the valve, should remove the asbestos packing, in order to avoid electrochemical corrosion damage to the valve stem.I just entered the library on the valve, to conduct inspections, such as during transport into the water or dirt to wipe clean, re storedThe import and export of valves to use wax paper or plastic sheet sealed to prevent dirt insideThe valves on the machined surface rust in the atmosphere should be coated with anti rust oil, protectI placed outside the valve, must be covered with linoleum or tarpaulins like rain, dust items. Keep the storage of the valve clean and dry
Q:What does the "PN" mark on the valve mean?
The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)
