2.Feature

JD745X multifunctional hydraulic control valve is composed of the main valve and regulating valve and take over the system, the valve body adopts once-through body, the main valve control room for the diaphragm or piston type double control room design, hydraulic control valve added a control room, strengthen the function of the control of the main valve, achieved to pump export slowly open, open, closed, as of multi-function control, implement a valve, a multifunctional control of pump export adjustment. JD745X multifunctional water pump control valve to take over the control system adopts the regulator, by setting valve opening, easy to realize to the control parameters, such as the main valve opening speed, hydraulic slowly-closing speed and so on.

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:Yongde jiekelong valves and valves of the good faith
Interior decoration is the most cost-effective brand, switches, sockets, Zhejiang, Yongkang, France and Germany electrical appliances. Plumbing valve, Zhejiang, Yongde, Yongkang letter. Bathroom accessories Fujian Nanan Jomoo bathroom.
Q:What does valve J41H-16C mean?
J- stop valve4- flange type connection1- structure typeH- alloy steel seal16- nominal pressure 16 kgC- body carbon steel
Q:How do you calculate the flow of the valve?
Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
Q:1/2, what does 1/4 valve mean? I don't understand. What does this number mean?
Valve international universal caliber national nominal diameter1/4 inches, =2/8 inches, =2 minutes, =DN8 (mm)3/8 inches =3 points =DN10 (mm)1/2 inches, =4/8 inches, =4 minutes, =DN15 (mm)3/4 inches, =6/8 inches, =6 minutes, =DN20 (mm)1 inches =DN25 (mm)1 1/4 inch =DN32 (mm)1 1/2 inch =DN40 (mm)2 inches =DN50 (mm)
Q:What's the valve specification DN20?
It's not clear what you want to ask
Q:Valve difference
Valve difference, or you should ask the classification of valves, valve classification, there are several sub methods, some according to the model, and some are by use, then each kind of valve is divided into several categories and models. Take the trap for example, it is a kind of valve, and then it is divided into steam traps, air traps, float traps, and so on. If you really want to know the difference between the valve you search the Internet under the classification of the valve, there are a lot of articles, or you directly to the trap inside www.ssfmsh.com find an article on the valve type article, can not give you a specific address, is not allowed here. You work hard, go find kazakhstan. I hope my answer will be helpful to you.
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:How are the types of valves classified?
Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion.
Q:The difference between fire general valve and fire fighting special valve
Fire fighting valves are mainly signal valves and alarm valves and water indicators, etc., other gate valves, butterfly valves, pressure relief valves and filters are common valves.
