500 x relief valve by the main valve, pressure relief/holding pressure pilot valve, needle valve, ball valve, micro shape filter and pressure gauge of hydraulic control of system. Use of hydraulic automatic operation, can make the pressure release valve and can be used for holding pressure valve. As a pressure relief valve, it can maintain water supply way pressure under the TVC of set; For holding pressure valve, can maintain the main valve upstream water pressure above the set value, maintain the main valve upstream water supply pressure.
500 x relief valve using hydraulic control themselves, do not need other devices and energy, maintenance is simple, one valve is multi-purpose. 500 x relief valve is widely used in water supply network system of high-rise buildings, residential and urban water supply engineering.
1, A pressure relief valve: when the pressure relief/holding pressure pilot valve is adjusted for pressure condition, water through the needle valve, the main valve control room, ball valve, A pressure relief/holding pressure pilot valve, ball valve B of exports, at this time the main valve is fully open. When the inlet pressure exceeds the pressure relief/holding pressure pilot valve set TVC, pressure pilot valve will automatically open, channelled through ball valve C section water, make the line pressure. When the pressure recovery to TVC, pressure relief valve automatically shut down. As a pressure relief valve, ball valve normally open.
2, for holding pressure valve: when the pressure relief/holding pressure pilot valve adjustment of the state, as long as the main valve import water pressure is lower than the pilot valve set point, pilot valve is closed. The main control room booster, the main valve closed.
3, when the main valve upstream water supply pressure exceeds pilot valve set pressure, holding pressure pilot valve to open, the control room of water through the ball valve to the export, the control room main reducing valve open, began to water supply, that maintain the upstream water pressure. For holding pressure valve, ball valve normally closed C or substituted a plug.
- Q: the rest are hot, the living room outside all the heating pipe valve closed, the living room heating is still not hot, after the water for a while hot, and cold
- There is gas, causing water not to cycle, give up on the cure! Are you single family control?Single family control, the general bedroom and living room is not all the way, the living room, this way, the vent valve in the toilet, I was on the road in the balcony! The bleeder valve, is made of copper tube in the device above two, as long as can step in his place, the bleeder valve with a small angle, feet above a needle, with a needle to drill a well, there is a long time not float, a gas exhaust out that leads to water circulation,Why do you put a little while, the water is hot, a little cooler, the water does not cycle, is dead water, can not cool it?I am building plumbing, believe me, yes, these are some common problems, especially on the top floor!
- Q: Valve category can fill the trunk door, branch valve Mody?
- Valve category can fill the trunk door, branch valve? "no, too general."
- Q: What is the valve?
- The definition of a valve "valve" is defined in the fluid system, used to control the direction of the fluid, pressure, flow device. A valve is a device that flows or stops the medium (liquid, gas, powder) in a pipe and equipment and controls its flow. Valve is the control component of pipeline fluid transportation system. It is used to change the passage section and medium flow direction, and has the functions of diversion, cut-off, adjustment, throttling, check, diversion or overflow, pressure relief, etc.. For fluid control valves, valve from the simplest to the most various valves automatic control system used in complex, its many varieties and specifications, the valve nominal diameter from industrial piping and instrumentation valves tiny tolarge diameter 10m valve. The valve can be used for the control of water, steam, oil, gas, mud, all kinds of corrosive medium, liquid metal and radioactive fluid and other types of fluid flow, the valve working pressure from 0.0013MPa to 1000MPa ultra high pressure, working temperature from ultra low temperature to high temperature of 1430 DEG -269. Control valve can be a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic dynamic, electromagnetic hydraulic, electric hydraulic, pneumatic and hydraulic, gear, bevel gear drive; in pressure, temperature or other forms of sensor signals under the action according to the requirements. Or do not rely on a simple sensor signals to open or close the valve on the drive or automatic mechanism to make the opening and closing parts for lifting, sliding, rotating or turning motion, thus changing the size of the flow area to achieve its control function.
- Q: What courses in the University involve valves?
- Pressure vessel design, the valve is essentially a pressure to withstand the container. The valve can be understood fundamentally.
- Q: How to check the quality of the valve?
- First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level.Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem.Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.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: 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: The valve has a clear opening and closing sign. What does this sentence mean?
- Not only on the valve is enough to mark, here means that at the scene can see the installation of the pipe network on the valve open or shut?!
- Q: What valve is the VENT?
- VENT generally use a check valve (resembling a screw, spring preload), also directly using the plugA two-way sealing type ball valve for example, in order to detect the leakage of the pressure after the end, also for pressing the cavity is convenient, usually in the body cavity external to the up position to open a checking leak, which is VENT.
- Q: What does valve 41F-40C mean?
- Incomplete model4 is the flange1 is the formF is seat material, fluoroplastic, ptfe,40 nominal pressure 40 kgC body material carbon steelFront also have to add valve category code, such as manual ball valve, Q41F-40C manual code is 0, but this 0 we don't write out, so only written Q41F-40C electric ball valve, Q941F-40C 9 represents electricGate valve is Z41F-40C
- Q: There is a rectangular hole in the valve core, which the heating company repairman gives to the bolt. Rest assured, I do not want to heating, but my indoor temperature is low, I suspect that the repairman mischief, deliberately give me lower temperature
- The heating valve refers only to a radiator system accessories, is a type of valve, the valve commonly used heating system on the market is mainly divided into: gate valve, ball valve, safety valve, balance valve, globe valve, regulator valve, relief valve, pneumatic control valve.
