Q:What's the material of j41h-16p's valve?
Stop valve characteristics:(1) the structure is simpler than the gate valve, and the manufacture and maintenance are more convenient.(2) the sealing surface is not easy to wear and scrape, good sealing, when opening and closing, there is no relative sliding between the valve and the sealing surface of the valve body, so the abrasion and abrasion are not serious, the sealing performance is good, and the service life is long.(3) when opening and closing, the valve stroke is small, so the cut-off valve height is smaller than the gate valve, but the structure length is longer than the gate valve.(4) the opening and closing moment is big and the opening and closing are more strenuous.(5) large fluid resistance, due to the valve in the medium channel is tortuous, large fluid resistance, power consumption.(6) the flow direction of medium nominal pressure PN is less than or equal to 16MPa, commonly used downstream, medium from the valve under the direction of flow; nominal pressure PN = 20MPa, using reflux, medium from the valve on the downstream direction to increase the seal. When used, the cut-off valve medium can only flow in one direction, can not change the direction of flow.(7) when fully open, the disc is always subject to erosion.
Q:What is the diameter of a general pipe valve?
In fact, the essence of the problem is the corresponding relationship between the nominal diameter and other dimensioning methods. Valves are generally marked with nominal diameter (DN***), such as DN150, DN100 and so on. There are many kinds of marking methods for pipes, such as outer diameter, inch inch, nominal diameter, etc.. Only when the other dimensioning is converted to nominal diameter, the valve and the pipe correspond to each other.
Q:How to quickly identify the types of valves?
The "Practical Handbook" valve design on the valve structure, with precision, surface roughness and typical design standard, the valve has hundreds of models, and continue to have a new valve, see a written one, is shorthand
Q:What does valve DN50/80 mean?
Hello landlord DN50 valve refers to the valve diameter of 50mm DN80 is 80mm if the valve is opening and closing function, so the valve diameter should be and pipeline with the diameter or smaller number, large waste, butterfly valve to be stuck in the flange, the influence of flow.If the role of the valve is adjusted, and that caliber will be different from the pipe diameter, this is not to reduce the cost of the problem, is a result of calculation, and this calculation results with flow, pressure drop and valve resistance curve.For example, control valve, usually smaller than the pipe diameter, such as pressure reducing valve, will be smaller than the pipe diameter to two, such as 57mm pipe with DN50.
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:How can the material be checked by valve approach? What experiments do you need?
May refer to the valve pressure test principle and the pressure test matters needing attention.(1) in general, the valve shall not be subject to strength test, but the body and bonnet shall be subjected to strength tests after the repair of the valve body and bonnet or corrosion damage. For the relief valve, the constant pressure and seat return pressure and other tests shall be in accordance with the specifications and the relevant regulations.(2) the installation of the valve should be done for strength and tightness test. Low pressure valve sampling 20%, if not qualified should be 100% of the inspection; medium and high pressure valve should be 100% of the inspection.(3) the installation position of the valve shall be in the direction of easy inspection during the test.(4) welding connection valve, not with blind plate pressure test can be used when the cone seal or O ring seal pressure test.(5) when hydraulic test, the valve air will be excluded as much as possible.(6) the pressure should be increased gradually during the test, and the pressure will not be sudden and sudden.(7) strength test and sealed test duration is generally 2~3min, important and special valves should last 5min. Small caliber valve test time can be a little shorter, large caliber valve test time can be longer. During the test, the test time can be extended if in doubt. Strength test, does not allow the body and bonnet sweating or leakage. Sealing test, the general rotor valve only once, the safety valve, high pressure valve and other raw valve to be carried out two times. When testing for the low pressure, large diameter valve is not important and there are provisions to allow leakage of the valve, allowing a small amount of leakage; the common valve, power station valve, marine valves and other valve requirements vary on leakage requirements according to relevant regulations.
Q:What does 3/4''mean in the name of the valve?
Upstairs answer is very clear, 3/4 refers to the caliber of the valve is 3/4 inches, equal to the national standard DN20, (20mm) commonly known as 6 points. The most common family is 1/2, equal to DN15, commonly known as 4 points. Another marked 1.6 refers to the pressure of 1.6Mpa., equal to 16Kg, to bear the pressure.
Q:What valve should be used to test the water valve?
1, ball valve.2, the water test valve can be ball valve, gate valve, stop valve, installed in the fire sprinkler system at each level of the end of the pipe.
Q:What is the difference between a stop valve (a power station valve) and other valves?
The cut-off valve is low in and out of the structure, usually used in the case of pressure loss, the cut-off valve is not through the form. Gate valve is straight through type.
Q:Dalian hi Max Valve Co., Ltd.
I have to do the technical sales colleagues is high inside out now before the inside sales revenue is also good about one hundred thousand a year as sales of a great degree of luck the.I do not know what the specific circumstances, what age, in this line for several years, there is the opportunity to communicate with the landlord and make progress together.
