Q:Why can't the clip type check valve be directly connected with the pipe mouth or other valves?
The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
Q:What kind of valve is it? How do you see the status of the switch?
This is a ball valve, that is, usually said cut-off valve, to determine the switch state is carefully look at, there is a switch on the status of the arrow, you will understand.
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)
Q:The valve is rusty and can not be opened. What shall I do?
Spray with rust removing agent on the rusty rotating parts of the valve. Then use an afterburner to make a tentative rotation. Open it and turn it in the opposite direction. And then spray rust remover. Repeat this several times, and the valve will probably open. Seriously rusty valve, if it really can not open, simply replace it.
Q:Several problems about valve parameters
Is the flow through the valve. That is to say, when the valve is fully open, flow through the valve size.
Q:Which valves are installed in a directional manner?
There are balance valve, safety valve, pressure relief 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 "DN15" mean? What does "PN 16" mean?
DN15 refers to the diameter of the valve, that is to connect the caliber of the pipe.PN16 means pressure, that is, 16 kilograms (1.6MPa).
Q:Valve difference
That depends on where it is used! No one knows how many kinds of valves. If you have water, you can use gas, food, and so on.
Q:What does the J41Y-100I valve type mean?
Stop valve typeJ represents the cut-off valve, 4 (flange) on behalf of his connections, 1 (straight) on behalf of his structure, Y (seal) on behalf of his seat sealing surface or liner material code, 100 is the nominal pressure value, I (chrome molybdenum steel) is the code of the body material
