- Q:Pump, valve, these belong to the material?
- Pumps, valves are electromechanical equipment, belonging to a class of hardware fittings, but not material!
- Q:Which direction is the valve? Which direction is it?
- Ball valve: handle and Guan Daocheng 90 degrees for the pass, 180 degrees to open (ie in line with the direction of the pipe open)The gate: clockwise, counterclockwise.
- Q:What does the whole copper valve mean?
- Except the handwheel, all the material of the valve body is copper
- Q:What are the ten major brands of China's valves?
- In the fluid piping system, the valve is the control element, its main function is to isolate the equipment and the piping system, regulates the flow, prevents the backflow, the adjustment and the excretion pressure. As the piping system selects the most suitable valve, it is important to understand the characteristics of the valve and the steps and the basis for selecting the valve. If you want to buy, you can choose the following aspects: 1. Select the valve according to the adjustment of medium parameters: two. According to prevent media backflow, choose the valve: three. According to the nature of the media, choose the valve. As for the brand if you can refer to the ten brands to buy China ten brands online, for example, Langao valve, a valve on the river, Amico, SF, card, open the valve on the market these are famous brands, you can refer to.
- Q:How big valves are used in a DN159 pipe?
- Nominal diameter DN150 corresponds to the outer diameter of De159To say DN159 is wrong, because DN is the nominal diameter (diameter in the middle of the tube wall)De159 refers to the outside diameter (outside the diameter of the wall)DN39 should be DN32. Nominal diameter 32, outer diameter 39.
- Q:What is a lift rod valve?
- Lever valve stem nut in the valve plate, it with the disc (hand wheel) to open the turn, its stem pull the valve head and higher than the valve disk, also known as the bar valve. It is different from the dark rod valve, dark rod valve stem nut in the valve body, when the disc rotates, the stem will not rise.
- Q:What is a heavy body valve?
- You should be asking what a heavy-duty valve is.This is only in the ordinary gate valve and cut-off valve on the distinction. Nowadays, ordinary gate valves and cut-off valves are divided into heavy-duty ones. Medium and light three kinds ~!
- Q:How many kinds of valves are there in the water pipes?
- butterfly valveThe butterfly valve has the advantages of simple structure, small volume, light weight, only by a few parts. But only can rotate 90 degrees rapid hoist, simple operation, while the fluid control valves have good properties. The butterfly valve in the fully open position, the disc thickness is only when the medium flows through the power, by the valve the pressure will be very small, so it has better flow characteristics. Our company is mainly metal plastic butterfly valve, eccentric butterfly valve, butterfly valve, inlet butterfly valve, wafer butterfly valve and so on.Globe valveBall valve and plug valve is the same type of valve, only its closure is a sphere, the sphere rotates around the body center line to achieve the opening and closing the valve. A valve in the pipeline is mainly used for cutting, distribution and change the direction of media flow, the ball valve is a new valve in recent years has been widely using.
- Q:Mechanical valve
- From the appearance of it is not too good to say, if it is the valve, only one-way valve.The valve usually consists of the stem, spool, seat, body, seal, and so on. This figure feels more like a filter that connects a pressure vessel to an inlet or an inlet.I've seen a lot of filters like this, usually open with -drain filter inside. Play a role in the filter of some large magazines, you can change, more metal, the mother is relatively small (relatively large hole)
- Q:In the fire drawing, what valve does the following valve represent?
- This is definitely the sprinkler system. It's a drain valve, a ready valve. You check it. I can't remember it. It has not been drained for a long time.
