Q:What are mine valves?
You want to see what works on the use of what media, in the choice of what type of valve is more appropriate. Shanghai HuquanValve manufacturers, veteran enterprises, trustworthy.
Q:Where is the valve used?
Oil and gas pipelines, gas stations, gas stations, petrochemical plants, water plants, etc..The valve (Valve) is a mechanical device that controls the flow, flow, pressure, temperature, etc. of a fluid medium. The valve is the basic component of the piping 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 kind of valve is it? How do you see the status of the switch?
This is a ball valve, that is, usually said cut-off valve, to determine the switch state is carefully look at, there is a switch on the status of the arrow, you will understand.
Q:How about the quality of FITOK valves?
The United States fitok valve is the main valve and needle valve, globe valve instrument and meter tube also do.The quality of foreign valves are still good. Everyone thinks French valves are better than American ones. But the price is not cheap
Q:How can the material be checked by valve approach? What experiments do you need?
First of all, to check material certification, and secondly, the material appearance, shape and size of the initial test, again on the alloy material according to the standard spectrum analysis, the valve to do pressure test.
Q:What is the term "Z41H-16C" on the line?
When Z41H-16C opens the valve, when the gate lift height is equal to 1:1 times the valve path, the passage of the fluid is completely unblocked, but at run time, this position is not monitored. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position. Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.
Q:What does the torque of the valve mean?
The torque of the valve is the opening moment of the valve (valve torque): Newton meter.The opening moment, also known as the operating torque, is the most important parameter for selecting the valve actuating device. Opening torque is also a measure of the quality of the valve product is another important indicator, people in the evaluation of valve quality, commonly used valve opening light, flexible to describe it. In some advanced industrial countries in the pipeline valve standards, as one of the assessment indicators, and provides manual valve opening torque is not more than 360N • M. More than this moment, it is necessary to consider the use of suitable driving devices (such as electric, pneumatic, hydraulic devices). Some manufacturers will open the torque printed in the product samples, user-friendly.
Q:What are the major brands of valves abroad?
The best form is used to provide the valve and valve operating conditions, each brand has its own advantage.
Q:Valve should be strictly marked according to the direction of instructions and media flow direction to determine the installation direction,
Refers to the installation of the interface dislocation, misalignment or installation of the wrong size and forced connection, resulting in installation stress exists, in use, it is prone to abnormal damage.
Q:What valve should be used to test the water valve?
3, ball valve (ball valve should be a cut-off valve in the marine and marine field), standard GB/T21465-2008 "valve terminology" is defined as: opening and closing parts (ball) driven by the stem, and around the valve axis for rotation of the valve. Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media.
