Q:I'm going to put a solar energy and an electric water heater installed in the same hot water pipe, a valve, a valve open and close the valve B and vice versa the installation of solar and electric water heater, there can be no linkage valve?

In industry, you say this, such as using two butterfly linkage and composition of the three-way valve to use. But civilian should be few, demand is very little ah. It is estimated that you can only install two valves and then use both hands at the same time to perform linkage.

Q:What is the difference between the adjustable range of valve 50:1 and 100:1?

Adjustable ratio is also called adjustable range, if to R to indicate, then R=Qmax/Qmin should pay attention to the minimum flow, Qmin and leakage of different meanings. The minimum flow refers to the lower limit of adjustable value, it is generally the maximum flow rate of Qmax 2%~4%, and the leakage is fully closed when the leak valve, it is only the maximum flow rate of 0.1%~0.01%.Adjustable range 100:1 generally can not reach, the accuracy of this valve is very high.

Q:A kitchen, 2 bathrooms, in addition to the toilet, toilet (only cold water), the rest need hot and cold water supply, and hot water by solar water heaters and gas water heater selection. The kitchen is mainly a sink, each toilet for toilet, shower, washbasin, separate cold water faucet. I don't know how many metal materials I'll use now Thank youThe waterways are all dark!

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: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

Q:What does the "XV" valve mean?

XV if in front of the valve position, such as XV2211-011, then the XV indicates the switch valve, which is a representation of the Control Valve relative to the regulating valve.

Q:and today the boss told me that I would like to do a valve of the commodity inspection information, and nothing else to me, which master taught meI am a professional intern, our company is doing the valve outlet, today my boss asked me to do a valve inspection data, what other data are not for me, which foreign trade master teach me ah, depressed ah ah ah???

National commodity inspection; stainless steel products; plastic tableware; domestic porcelain; toys; wooden products; furniture; bicycles; baby carriages; shoes; clothing; lamps and lanterns; plates; household appliances; bamboo / Wood / rattan / willow / grass / banana / vine furniture etc.

Q:The low pressure in our factory is below 1.6Mpa, medium pressure is 2.5-6.4MPa, high pressure is 10-80MPa.Where's qusetion:1.6-2.5Mpa??? Which section does it belong to?. I think many of them are defined on the Internet But I didn't say, where's 6.4-10Mpa?

According to the GB standard test pressure GB/T13927, "industrial valve pressure test" valve in accordance with the pressure can generally be divided into the following categories:(1) vacuum valve: refers to the working pressure is lower than the standard atmospheric pressure valve.(2): refers to the low pressure valve nominal pressure PN valve is less than 1.6Mpa.(3) medium pressure valve: refers to the nominal pressure of 2.5Mpa, PN, 4.0Mpa, 6.4Mpa valve.(4) high pressure valve: refers to the pressure valve PN 10.0Mpa 80.0Mpa valve.(5) super high pressure valve: nominal pressure PN = 100.0Mpa valve.Normally the stresses are actually pressure (force per unit area). Is generally used to gauge our living environment under 1 standard atmospheric pressure as reference 0 (reference point 0), and the difference between the value of the gauge (pressure gauge usually display is the gauge). But in fact we live in 1 atmospheric environment, coupled with the income of the 1 gauge pressure value is the absolute value of pressure.Standard atmospheric pressure actually has standard engineering atmospheric pressure at (kgf/cm2) and standard physics atmospheric pressure ATM, the former used in the early years, and now generally use the latter. 1atm=1.0332at=1.01325bar (bar) =101.325kPa=0.101325MPa.The valve pressure mainly focus on two parameters: rated working pressure, such as PN16, said the rated working pressure is 16bar (1.6MPa); the maximum permissible pressure difference (this value, the greater the actuator thrust torque required with the larger).

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:Where is the hydrant main valve?

The fire hydrant generally has two sources, one is from the roof water tank, a water pump is from the housing, maintenance, should close the fire hydrant located on the riser inlet valve tube under the ring, generally located in the top and bottom, and then discharge, when the valve cannot be closed, the proposed closure of replenishment valve and the pressure stabilizing device of water tank, fire pump in manual state, drainage after maintenance. Watch out for fire.

Q:What's the difference between a valve and a valve?

The valve does not have an Ethernet platform, and the "one" valve does not contain any other fittings.
