Composite Pipe Suppliers

the meter calculates and analyzes to obtain the valve opening value when the piping system reaches hydraulic balance. 2. Differential pressure valve 1. Function: The differential pressure valve is used in the sealing oil system to adjust the air side sealing oil pressure, so that it always maintains a certain pressure difference with the gas pressure in the generator. 2.

Structure and working principle: This valve drives the sliding rod to move up and down through the difference of the input signal, and changes the opening of the valve to adjust the oil pressure. The sealing oil system is usually equipped with two differential pressure valves.

One differential pressure valve is the air side oil pressure regulating valve. It is connected between the inlet and the outlet of the air side oil pump and acts as a bypass pressure regulator. The signals are taken from the machine respectively. Internal hydrogen pressure and air side sealing oil pressure, the valve can automatically adjust the bypass flow according to the pressure change of the signal source, so as to ensure that the air side sealing oil pressure is always higher than the internal hydrogen pressure by 0.085MPa. The other differential pressure valve is the spare pressure regulating valve for air side oil, which is connected to the air side high pressure and low pressure standby sealing oil pipelines.

The signals are respectively taken from the hydrogen pressure in the generator and the air side sealing oil pressure, and the standby sealing oil is adjusted. Flow rate to ensure that the backup air side sealing oil pressure is always higher than the air pressure in the machine by 0.056MPa. 3.

The working Composite Pipe Suppliers of the differential pressure valve in the sealing oil system. The piston of the differential pressure valve introduces the hydrogen pressure in the machine (pressure p1), and the air side sealing oil (pressure p) that is adjusted and output is introduced under the piston.

, configurations and routes. It can be widely used for long-distance operation and control valves of various devices and production pipelines. Standard Parameters of AW Pneumatic Actuator AW Pneumatic Actuator 1. Basic design pneumatic double cylinder double piston fork-pull transmission mechanism; model AWxx=double-acting type; model AWxxS=single-acting type (spring return). 2. Rotation angle Double-acting type=90°; Single-acting type=90°; The angle can be adjusted from both ends -5O°+50°. 3. Working environment temperature: -20°C—90°C. 4. Air source pressure: 0.4-0.7Mpa (maximum 1.0Mpa).

Its nominal diameter is neither the outer diameter nor the inner diameter, but a nominal size similar to the inner diameter of ordinary steel pipes. Each nominal diameter corresponds to an outer diameter, and the value of the inner diameter varies with the thickness. Nominal diameter can be expressed in metric system mm or in imperial system in. Pipeline accessories are also expressed in nominal diameters, which have the same meaning as seamed pipes.

Globe Valve Suppliers

The general Globe Valve Suppliers temperature of stainless steel is less than or equal to 150℃, and the pressure range is 0.6-2.5MPA. It should be stated when ordering if it exceeds this stipulation. 2. Discharge valve, corrosion resistance: 1. PTFE has excellent adhesion to metal, general tensile resistance, and resistance to dilute acid and concentrated acid. 2. Use medium such as particles, oil, paper pulp, carbon dioxide gas (usable temperature of stainless steel material is -60℃-232℃). 3. It is strictly forbidden to use fluorine-containing ionic liquids (such as HF, etc.) and strong alkalis and phosphoric acid (temperature less than 150℃, concentration>30%). 4

. The general working temperature of stainless steel is -5℃-225℃, and the pressure range is 0.6-1.6MPA. Please specify when ordering if it exceeds this requirement. 3. Discharge valve: The glass-lined equipment is a vitreous glaze with high silicon content. It is made by coating metal tires at a high temperature of about 900 degrees.

It has good mechanical properties and corrosion resistance, can prevent the substitution of media and metal ions from affecting products that pollute products, and has a smooth surface, abrasion resistance, and a certain degree of thermal stability. This valve is resistant to various acids, alkalis, salt solutions and organic solvents except for phosphorus and phosphorus light media, hydrofluorocarbon, hydrochloric acid, sodium hydroxide, and potassium hydroxide. A. Corrosion resistance: 1. It can withstand general inorganic acid, organic acid, weak lye (P≤60℃ PH≤12) and organic agent medium. 2.

It is better than stainless steel in hydrochloric acid, nitric acid, and other strong corrosive media. It is strictly forbidden to use fluorine-containing ionic liquids (such as HF, etc.) and strong alkalis and phosphoric acid (temperature less than 150°C, concentration> 30%). B. Heat resistance, it is allowed to be used between -30°C and 240°C (temperature resistance is less than 120°C). C. It has a smooth surface. It is not easy to stick materials and easy to clean. E. Insulation: The impact resistance is as small as 2500 g/cm, so the impact of hard objects should be avoided when using it. F.

Bottom Valve Manufacturers

The turbidity Bottom Valve Manufacturers indexes of the filtered and filtered water before the transformation are extremely unstable, and the backwash cycle is irregular. After the transformation, the average turbidity of the filtered water is 2 degrees, the chroma is 5 degrees, and the backwash cycle is controlled at 30h. Because the valve is used to control the water inflow and drainage, and the opening degree of the valve and the backwash cycle are controlled by the program, the sand in the filter and the interruption of the backwash are basically eliminated. The water in each grid is balanced and the backwash intensity is ensured. ,

The operation cycle of the filter reaches a better state. The safe and stable operation of the filter tank is realized. Figure 4 3 Concluding remarks The cancellation of the filter control panel and the operation box makes the operation layout more concise and orderly; the cancellation of the vacuum system reduces the operating power consumption and at the same time enhances the reliability of the filter operation; the solution of the factors that affect the automatic control,

The filter tank is changed from manual control to program control, which realizes the good efficiency of filter tank operation and guarantees the quality of factory water. It can be seen that through reasonable technological innovation, the existing filter can completely achieve the water filtration goals and tasks set by the state in 2000.

The anti-corrosion of metal valves can be understood as coating the metal valve with a protective layer (such as paint, pigment, lubricating material, etc.) that protects it from corrosion, so that the valve can be manufactured, stored, transported or It is not corroded during the whole process of use. The anti-corrosion method of metal valves depends on the required protection period, transportation and storage conditions, valve structure characteristics and materials.
