Q:Comparison of foreign valves, such as Jiang Sen, SIEMENS, Honeywell, Watts, Tyco valves?
Johnson, SIEMENS, Honeywell is mainly in the electric valve inside, because they themselves do automatic control system, so the electric valve matching is strong, but also manufacturers own production, other types of valves they several brands are generally looking for OEM agents do, is not recommended.
Q:What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?
Pneumatic valve compared to the electric valve, the valve can be the same, rubber lined butterfly valve or other valves, pneumatic valve opening speed (Basic 1 second can be fully open), the price is lower than the electric valve. But there must be process air (4-6bar compressed air). According to my experience, if the scene has compressed air, it is recommended to use pneumatic valve, if there is no compressed air, it is recommended to use electric (electric valve expensive, open valve slow).
Q:What does the torque of the valve mean?
The opening moment (torque) is the force or torque that must be applied when the valve is opened or closed. Need to open and close the valve when the sealing pressure than the formation of closed and valve seat sealing surface between the two, but also to overcome between the stem and the packing between screw stem and the nut, the valve stem friction end bearing and other friction parts. Therefore, certain closing force and closing torque must be applied, and the required opening and closing force and opening and closing torque during the valve opening process are varied, in which the maximum value is at the closing instant or the initial opening moment. Design and manufacture of valves, should strive to reduce the opening and closing force and opening and closing torque.The open torque can be obtained by means of calculation or measurement, and can be obtained by hand torque measurement.
Q:How to find all kinds of mysterious valves of human body?
Many cell signal channels have been found, and if you can find each signal, the channel will be almost the same. That's the mysterious valve you want, but it's hard.
Q:Valve legend
This should be part of the thermodynamic device that represents the gate valve or butterfly valve
Q:How many triangular valves and other valves are used in kitchen and toilet decoration?
Landlord water and electricity installation? If you ask the water electrician to install it, you don't need to worry about it so much. You can wait for water electrician to install the hot and cold water pipe in place. We can count on you here.
Q:How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
For you to introduce the spreadsheet calculation, application basis, you according to this principle for valve correlation calculation:When A1 and B1 cells are used as parameters, the amount of computation is calculated by C1. If the formula is X+Y=? In the A1 cell, fill in the X; fill the Y in the B1 cell; fill in the C1 cell with "=A1+B1"; enter the carriage, and then calculate the corresponding value in the C1 cell. For example: fill in 5 in the A1 cell; fill in 8 in the B1 cell; enter the carriage, and then appear in the C1 cell 13. Other calculations are the same, you will calculate the valve formula, such as the above fill in, given the corresponding parameters, the same can be calculated.
Q:Valve connections - two how do different connections work?
The inlet and outlet of valve are respectively connected in two different ways: one end adopts flange connection, the other end adopts thread or socket.
Q:Who knows what the DE stands for in the valve DE50?
No, DE is DG, and DG stands for nominal diameter of valve
Q:What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?
Valve and ball valve is generally used in the main pipe, long-term use, butterfly valve is often used frequently,
