- Q:The customer sent an inquiry sheet, in which check valve DE50, balance valve DE25, stop valve DE75, and I want to know what de stands for, because the price of plastic and cast iron is different. What does de usually mean in the industry?
- No, DE is DG, and DG stands for nominal diameter of valve
- Q:What is the BV valve?
- It should be American Copeland company, BV series valves;
- Q:What's the difference between valves and valves without valves?
- The difference between a valve with and without a valve is that it has the advantage of having the valve exhaust. The advantage of the valve is that it can control the amount of exhaust and prevent the discharge of other fluids.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. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
- Q:Is the valve clockwise?
- Tap water valve is generally divided into two kinds, one is ball valve, and the other is gate valve. The ball valve wrench is vertical when the water pipe is closed, is a twist or reverse, 90 degrees wrench and water pipe is open when the direction; valve handwheel clockwise turn off, anti clockwise turn is open. Valve in the application should not be twisted too tight, so as to avoid the thread buckle, spool off. Ball valve applications save effort and durability.
- 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.
- Q:Which valves are installed in a directional manner?
- Regulating valve, stop valve, eccentric butterfly valve, check valve, one-way valve, solenoid valve, pressure reducing valve, drain valve and drain valve. Needle core valve, V ball valve, part of the ball valve, there is flow.Few. Such as floating ball valve, the central butterfly valve does not flow requirements. In general, if the regular manufacturers of valves, flow direction will indicate the flow of medium, to get the valve can see.
- Q:Hydrant valve leaks, how do you close other valves? Specific steps?
- Hello my name is Baidu know the long days of high water leakIn the vicinity of a common fire hydrant, there is a valve, which is convenient for fire hydrant maintenance, because fire hydrant repairs need to close the water source. Look around, it should be easy to find the valve. Switch valve is very simple, and the direction of the twist screw is the same, clockwise turn off, counterclockwise is open. Closed valve, fire hydrant will not leak, you can feel relieved to repair. I guess your fire hydrant is sealed rubber pad, aging causes leakage, it is a common disease of fire hydrants.
- Q:Measure the temperature with a thermocouple, and then how to make the valve open when the temperature reaches a certain value. When the temperature is lowered, will the valve be closed?Or tell my brother what is the knowledge, I can see it myself. Good. How much extra?!
- A relay or PID controller can achieve this operation, only need to set out, the valve can use electromagnetic valve, which belongs to a rapid opening and closing valves, only need to control the electric power to the valve can automatically open or closed, but the temperature change is large, if you want to keep the temperature constant. The best selection of regulating valve, constant temperature control valve will be before or after the valve, the main electrical control knowledge, do not know what I said is clear, remember the points, thank you!
- Q:I would like to ask commonly used water valve what kind of? What are the characteristics?
- The valve is usually composed of two parts: the actuating mechanism and the valve bodyAccording to the power used by the executing agency, the valve can be divided into four kinds: manual, pneumatic, electric and hydraulic. According to its function and characteristics, it can be divided into on-off valve, regulating valve, electromagnetic valve, electronic type, intelligent type, etc.According to the type of the body: through single seat, through two seater, angular, diaphragm, three links, eccentric rotation, butterfly, sleeve type, spherical and other 10 kinds of; according to the valve body material: cast iron, cast steel, forged steel, carbon steel, stainless steel, copper, plastic valves.
- Q:What is the purpose of the valve?
- Valve is a pipe accessory. It is a device used to change the direction of the passage and the direction of the medium flow, and to control the flow of the conveying medium.Valves have the following uses:1. Connect or cut off the medium in the pipe. Such as gate valve, globe valve, ball valve, plug valve, diaphragm valve, butterfly valve and so on.2 、 adjust and control the flow and pressure of the medium in the pipeline. Such as throttle, control valve, pressure reducing valve, safety valve, etc..
