1.Technical Date:
Size: DN20-DN800
Nominal Pressure: PN10/PN16/PN25
Operation Temperature: ≤80°C
Suitable Medium: Water.
2.Feature:
200 x vacuum regulator valve by the main valve, pilot valve, needle valve, ball valve, micro filter and pressure gauge of hydraulic control of system. After use, when the setting outlet pressure, stable outlet pressure automatically.
This product use pilot valve to control themselves, do not need other devices and energy sources, convenient maintenance, pressure control accuracy is high, affected by the inlet pressure and flow rate is small, reduced pressure regulator is reliable.
This series valve products are widely used in high-rise buildings, living quarters and other water supply pipe network system and urban water supply engineering.
- Q: What is a lift rod valve?
- The valve stem and valve plate are relatively fixed, and the valve stem rises up when the valve plate is raised
- Q: Valve category can fill the trunk door, branch valve Mody?
- Each of these types of valves have very different varieties, such as the valve can be divided into: self sealing valve, knife gate valve, gate valve, cryogenic insulation jacket valve, seal valve, vacuum valve, flexible valve seat seal, valve, gate valve, signal buried forged steel gate, cast iron gate valve and so on.
- Q: How can you replace the other valve when the main valve is not closed and no water is stopped?
- Not recommended against the flood to repair the valve, first you have to be repaired, second may be more complex, it is not easy. I have a bad experience this, take the valve, because it is plastic, and aging, the thread is broken, the new is not on do not have to flow out of the water, get it is. To find the valve, the mess!
- Q: How to check if the gas valve is open?
- There is a switch on the valve indicating that you can follow the above operation
- Q: What should be checked before using the valve?
- 5, check valve disc or spool movement is flexible and accurate, no bias, displacement or skew phenomenon6, spring-loaded safety valve should be sealed, positioning lever type safety valve should have the weight of the device7, rubber lining, lining enamel and plastic lined valve body surface should be smooth, the lining layer and the substrate firmly, no crack, blister defects, using high frequency electric spark generator to inspect the lining surface, not found in liner breakdown (white flash phenomenon) is qualified8, the valve flange sealing surface should meet the requirements, and shall not have radial scratches
- Q: The total valve of my natural gas was closed by the attitude I tried. Now I can't open it. I need to use gas. Who knows how to drive it? What skills do I have? I'm talking about the main valve.
- First of all, you have to determine the direction of the valve opening, usually homeopathy, it is off, the reverse is open. First: to determine the opening of the valve, are generally ball valve, screw 90 degrees on it. Second. At the top of your house, there is a button that can be pulled out. It's different from place to place. Some are pulled out half, and some are pulled out. Third: in the following there is a black disk like thing, commonly known as the gas sound core. This is the same as the second, pull out half or all, so that you can use gas, ha ha!
- Q: What valve does the high pressure by-pass valve DN254 * 800 belong to?
- High pressure bypass valve DN254 * 800 belongs to bypass valve.Function of bypass systemThe turbine by-pass device mainly has three functions of starting and overflowing:1 in the cold, warm and hot, the bypass system can realize the optimal unit start-up and shut-down in turbine operating conditions, start and stop curve can meet the requirements, two types of automatic and manual operation, with the establishment of the boiler steam temperature and steam turbine components. To shorten the start-up time.2. when the turbine is tripped, the bypass system can operate at a high speed and reach full open position.3., when the turbine load changes, the by-pass system has the regulating function, and the safety valve action can be avoided and the operation stability of the boiler can be improved when the instantaneous change of the moving state.The function of the bypass control valve:The main function of steam turbine bypass system is high pressure steam adjusting throttling and superheated steam cooling. The bypass valve to perform these functions at the same time and in low noise, small vibration, valve resistance to achieve its goal of temperature and pressure loss under the condition of touch.
- Q: What is the difference between a stop valve (a power station valve) and other valves?
- Compared with other valve products, the valve is characterized by high temperature and high pressure. If the pressure is lower than that of the universal valve, it is also lower than the common valve. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.The utility model is suitable for cutting off or connecting the pipeline medium on the pipelines of various systems of the fire power plant. Applicable medium: non corrosive media such as water and steam. Compared with other valve products, the valve is characterized by high temperature and high pressure and unique self sealing design. The higher the pressure, the more reliable the seal is. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.
- 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 advantage of using three way valves?
- Three way valve generally has a cut-off, regulation, diversion, and prevent counter flow, voltage regulation and overflow and other benefits, because of its benefits more, so the use of the three valve is extremely extensive, in the valve industry is also very important.
