A, product overview
ZLF (ZL - 4 m) series for flow control valve (self balancing valve) is a kind of intuitive easy flow adjusting control device, the network application of the valve can be directly set according to the design flow, the valve can be used in water, automatic eliminate the remainder of the pipeline pressure head and flow caused by pressure fluctuation is poor, no matter what the system pressure change all the set flow rate unchanged, the valve is finished at one time, these features make the network flow control to the net work for simple flow distribution, effectively solving the hydraulic imbalance between the network.
B,Technical parameters
1, medium temperature 0-150 ℃
2, work pressure differential 20-600 kpa
C, the performance and features
1, can be set according to the requirements of design or the actual flow rate, the system can automatically eliminate the differential pressure fluctuation, the flow rate unchanged;
2, to overcome the system cold hot uneven phenomenon, improve the quality of heating (cooling);
3, completely solve the proximal differential pressure big, distal small pressure difference;
4, reduce system circulating water, reduce the system resistance;
5, reducing design effort, do not need to complex pipe network hydraulic balance calculation;
6, decrease the difficulty of the network turn complex net work is simplified to a simple flow distribution;
7, be exempted from the flow of heat pipe heat source switch more redistribution work;
8, flow display values are based on random calibration test bench, flow (m3 / h).
- Q: Valve connections - two how do different connections work?
- The inlet and outlet of valve are respectively connected in two different ways: one end adopts flange connection, the other end adopts thread or socket.
- 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 courses in the University involve valves?
- Principles of Chemical Engineering (basic courses in chemical engineering and Technology)You always have to consider the problem of the valve when you design the pipe
- Q: The expert can tell me how to install this valve, and what fittings to use on both sides
- It looks a bit like the butt weld butterfly valve. The two sides are welded to the pipe. There is a step on either side of the valve. Overhead welding
- Q: Hydrant valve leaks, how do you close other valves? Specific steps?
- Crown valve pressFirst, make sure the front of the fire hydrant has a gate valve or butterfly valve Yes, it will be closed and replaced by the lineNo, then useSecond, the pressure of the pipeline to see how big, and if it is rare, replace it with water
- Q: What does the RF of the valve mean?
- The flange flange can be applied to the HG/T flange standard, or any other flange standard. HG/T will be more detailed
- Q: What does "DN15" mean? What does "PN 16" mean?
- DN15 refers to the diameter of the valve, that is to connect the caliber of the pipe.PN16 means pressure, that is, 16 kilograms (1.6MPa).
- Q: What items and detailed procedures should be inspected for valve size inspection?
- The American Standard (American Society of mechanical engineers ASME B 16.10-2000). Internet access can be downloaded, such as free standards to share and download sites. If you need any other valve standard, send me the mailbox.
- Q: How much is the 150LB of the valve?
- 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: 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.
