Q:What do the Z, J, H and D represent in the valve type?
:Austenitic stainless steel, copper alloy, plastic, rubber, nylon plastics, fluorine plastic, Cr stainless steel, hard alloy, rubber lining, Monel alloy, valve body material
Q:How to check the quality of the valve?
First, visual inspection of the valve appearance, followed by a spectrometer to check the material, material, and then look at the hydraulic test pressure, whether there is leakage.
Q:Why is copper used in cryogenic valves?
Contact with water does not corrode easily。he influence of temperature on copper is smaller than that of steel. Especially in the valve stem, there is also the important gear part, copper!
Q:What is the difference between a stop valve (a power station valve) and other valves?
High pressure, special material, complex structure, seldom manual operation.
Q:What does the "Z45T-16" valve mean?
Z - gate valve4 - flange connection5 - Dark pole, stem non lifting (gate valve structure)T - copper alloy, valve sealing face code16 - pressure code, 1.6MPaMaterial code for grey cast iron valves of nominal pressure less than or equal to PN16 shall be omitted in model preparation.May refer to JB/T 308 valve model compilation method
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.Valves: valves (Valve) control the flow of fluid medium flow, flow, pressure, temperature and other mechanical devices, valves are the basic components of the pipe system. Valve fittings are technically similar to pumps and are often discussed as a separate category. Valves can be operated by hand or hand wheel, handle or pedal, or by control to change the pressure, temperature and flow change of fluid medium. The valve can perform continuous or repeated operations on these changes, such as a safety valve installed in a hot water or steam boiler. In more complex control systems, automatic control valves are required depending on external inputs (i.e., regulating the flow through the pipe to the changing setting points). Automatic control valve without manual operation, according to its input and settings, so that the valve accurately control the requirements of fluid medium. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:What is the difference between low pressure valves and medium pressure valves and high pressure valves?
Low high is just a general statement, such as the height, there is no clear distinction between what theNow the pressure piping fittings design is specific to the pressure value, not to say that the place to install a medium pressure valve.The pressure piping is generally classified according to the pressure, and the valve can be distinguished by this.Of course, you say 2 of the medium pressure valve is also OK, belong to the low-pressure valve, no one was investigatedBy pressure:1 、 low pressure pipeline engineering pressure less than 1.6MPa;2 、 medium pressure pipeline engineering pressure 1.6-6.4MPa;3 、 high pressure pipeline engineering pressure 6.4-10MPa;4 、 super high pressure pipeline engineering pressure 10-20MPa.
Q:What kind of valves are best used for sand drain valves?
Looking at the domestic sand discharge conditions, the more commonly used plate valve and butterfly valve these two, but generally reflect the service life is not long, it will not be long before the sand leakage, the need for regular maintenance, low efficiency, affecting production. In recent years, the industry has also appeared in various kinds of new type of valve, take little effect, but also has a valve using the excellent response, talent shows itself, long service life, no maintenance, model for the special valve industry Yu powder FQD672 and FQD643,It is understood that the valve industry has been to focus on Yu powder (sand) on body condition, especially the delivery of viscous pneumatic conveying system, special valve type FQD672 and type FQD643 powder successfully developed specifically for the design of sand material conditions, erosion resistant, anti adhesive seal design, automatic compensation, to ensure zero leakage absolutely, efficient and longevity, is applied to the resin sand casting industry (coarse sand) sand core shape of the high-speed exhaust conditions, you can try to understand Baidu......
Q:How does the valve close?
Rotate it, turn it clockwise. Spherical valve, then hit a cross shaped on the line.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.
Q:How do I open the gas valve?
Third: in the following there is a black disk like thing, commonly known as the gas sound core. This one is the same as the second one, half or all. 1, according to the routine, now the handle position shows that the valve is open. 2, if the handle rotated 90 degrees, the gas pipeline gas has no change, should be the stem slipped, can not drive the valve ball rotation. Try rotating several times. If it still doesn't work, ask a professional to check it out.
