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: 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?: Back valve, DE50 balance valve, DE25 stop valve, DE75, what do you mean by "de"?Diameter DEThe diameter of a general plastic tube is indicated by DE in EngineeringNominal diameter is the size of all piping accessories in the piping system. The nominal diameter is a convenient round integer for reference and is not strictly related to the processing size. The nominal diameter follows the letter "DN" followed by a number sign.

Q: Is the heat jacketed valve fitted with flanged flanges?: Insulation valve is the standard valve, just in order to ensure the link bolt flange to super space, usually a large ball than normal level, such as the use of the path is DN80 flange, flange is DN100, so is the standard, but the size of flange connecting with other valves are not the same.

Q: What's the name of the valve?: Specific models only go to the original manufacturers to find, and want to use other valve replacement is not impossible, want to provide detailed parameters. Let's go to the valve manufacturer!

Q: If the valve in the pipeline throttle, such as open and open 50%, the valve before and after the pressure of how to calculate, how the flow changes?: Well, it's not easy. And you do not give the specific structure of the valve, so there is no way to talk about the calculation. The simplest way is to install the pressure gauge and the flow meter on both ends of the valve, and read the data directly.

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: How much is the 150LB of the valve?: 150Lb=2.0MPa=20 kg.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.

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: What kind of valves are best used for sand drain valves?: Looking at the domestic sand discharge conditions, the more commonly used plate valve and butterfly valve these two, but generally reflect the service life is not long, it will not be long before the sand leakage, the need for regular maintenance, low efficiency, affecting production. In recent years, the industry has also appeared in various kinds of new type of valve, take little effect, but also has a valve using the excellent response, talent shows itself, long service life, no maintenance, model for the special valve industry Yu powder FQD672 and FQD643,It is understood that the valve industry has been to focus on Yu powder (sand) on body condition, especially the delivery of viscous pneumatic conveying system, special valve type FQD672 and type FQD643 powder successfully developed specifically for the design of sand material conditions, erosion resistant, anti adhesive seal design, automatic compensation, to ensure zero leakage absolutely, efficient and longevity, is applied to the resin sand casting industry (coarse sand) sand core shape of the high-speed exhaust conditions, you can try to understand Baidu......

Q: What are the most common types of valves?: From the controllable and uncontrollable division (personal opinions, according to our factory valves used to explain)1. hand operated: gate valve, globe valve, ball valve.2. control: single seat valve, two seat valve, ball valve (O ball, V ball), eccentric rotary valve, butterfly valve, diaphragm valve
