Electromagnetic pulse valve is to control the size of the oil in the oil pressure. Usually installed in the main oil or oil in the back-pressure shock absorbers to reduce the impact of the shift and hydraulic lock unlock, so that equipment to maintain steady state operation. Technical requirements: 1, the product of the working pressure of 0.1MPa ~ 0.7MPa, medium oil through the air in addition to water treatment. 2, in the state of the product nominal gas supply pressure, the solenoid valve operating voltage of 85% of rated voltage, open electromagnetic pulse valve response time should be less than 0.03s. 3, the working gas supply pressure when 0.1MPa, you can make the pulse valve closed. 4, the product should be able to withstand the pressure of 0.8MPa of air. 5, under specified environmental conditions, electromagnetic coil housing insulation resistance should be greater than 1MΩ. 6, at room temperature 5 degrees to 35 degrees, relative humidity less than 85% of the conditions, electromagnetic coil casing can withstand voltage 50Hz, 250V, which lasted 1min no breakdown. 7, electromagnetic pulse valve withstand a frequency of 20Hz, the full amplitude of 2mm, which lasted 30min after vibration should be able to work properly. 8, under normal conditions of use, lifetime cumulative patch should be more than 80 million times. 9, look no valve coating flaking, scratches, burrs and other damage. 10, with a large-caliber spin injection ultra low voltage electromagnetic pulse valve for air pressure is less than 0.1Mpa, using compressed air, not at the same time with the impact of the gas pipeline network, operation stable and reliable. (0.05 ~ 0.1Mpa) according to the angle and the air inlet valve in the form of exports and imports can be divided into three types: a) rectangular electromagnetic pulse valve: a right angle to the import and export, directly affected by the signal diaphragm valve control; b. ) straight-through electromagnetic pulse valve: 180 degrees of import and export, directly controlled by the signal diaphragm valve; c) Submerged electromagnetic pulse valve: air inlet submerged in the air bag, directly controlled by electrical signals diaphragm valve. In addition to the conventional three spin injection valve there is a large diameter ultra-low-voltage electromagnetic pulse valve. Performance test: 1, the threshold voltage for the nominal test pressure of clean air, 85% of nominal input voltage of the solenoid valve in the intake port access supply pressure solenoid pulse valve, a width of an electrical signal 0.03s, checks Electromagnetic pulse valve opening is normal. 2, to close the intake port pressure test in the access valve supply pressure is 0.1MPa electromagnetic pulse of clean air, the input electrical signal to close the valve, check valve is reliably closed electromagnetic pulse. 3, pressure resistance test access at the inlet supply pressure solenoid pulse valve clean air of 0.8MPa, continuous 60min, the case part of the sealing gas leaks on the check valve electromagnetic pulse. 4, insulation resistance test (1) 500V, scale range of 0MΩ ~ 500MΩ, accuracy class 1 megger, under specified environmental conditions, measurement of electromagnetic coil insulation resistance of the shell. (2) the temperature and humidity inside the valve is placed, the temperature set at 35 degrees, relative humidity of 85% under the conditions imposed between 50Hz and solenoid valve, sinusoidal AC voltage of 250V, which lasted 1min, Check for breakdown. 5, anti-vibration test the valve fixed vibration test bench withstand vibration frequency of 20Hz, the full amplitude of 2mm, vibration lasted 30min after the check valve fasteners each part if there is loosening, are working properly. 6, the diaphragm service life test in the intake port access electromagnetic pulse valve nominal pressure of clean air, enter the width of the solenoid valve for 0.1s, 3s interval for the nominal voltage value and record valve continuous or cumulative work times. FRL it works: First, compressed air into the air filter, after the removal of water purification filter ash into the valve, pressure control after the gas pressure to meet the requirements of the pneumatic system, the output of the regulator of gas last into the lubricator, the lubricant mixed with compressed air atomized exports pneumatic devices together. The main performance characteristics of the pressure regulator valve pressure relief valve characteristics under certain flow, a function of the relationship between the output pressure and the input pressure (which can check the manual). Pressure relief valve characteristic curve shows contrast, when the output is low pressure, flow properly, the regulator valve for best performance. When the output of high pressure, flow is too large or too small, poor valve performance and stability. Flow characteristics flow characteristics when the input pressure is constant, a function of the output flow and pressure between output (can check the manual). The flow characteristic curve of the pressure reducing valve, the input pressure is constant, the lower the output pressure, the smaller the change in flow rate caused by fluctuations in the output pressure. The structure of the regulator valve directly affects the accuracy of the valve. For direct-acting valve, the spring stiffness, the higher the voltage regulator accuracy. But spring stiffness can not be too small to work with the valve pressure and adapt nominal flow; the larger the diameter of the diaphragm, the regulator accuracy is better, but not too much, so as not to affect the size of the spring stiffness and valve structures; ensuring sealed Under the premise, should minimize friction seal heart valves produced by the regulator in order to improve accuracy. For the pneumatic control system to work properly, the choice of valve should consider the following questions: 1, according to the required operating pressure, pressure range, maximum flow and voltage accuracy to select valve. The nominal flow valve is the main parameter, generally corresponds to the valve port size. Regulators should be chosen high accuracy precision pilot valve. 2, flammable, explosive and other people should be close to the situation, should use an external pilot valve. But remote distance should not exceed 30m. 3, the valve is generally used pipe connection, special needs can also be used to connect the plate. Often associated with the filter valve, oil mist in conjunction with, if this should be considered or used pneumatic FRL FRL, to save space. 4, in order to facilitate the operation, valves are generally mounted vertically, and press the arrow points to take over the body, you can not install the wrong direction. Before installing to do cleaning work. 5, the valve should not loosen the grip to avoid intimal flap valve due to chronic stress and deformation. Reduction Valve is the use of a control valve opening and closing parts of the body to regulate the flow of the medium, the pressure medium is reduced, after Reduction Valve same time with the role of the pressure regulating valve opening and closing parts, so downstream pressure remains within a certain range, and the valve body or valve sprayed into the cooling water, the temperature of the medium is reduced, this known pressure reduction valve temperature valve. Characteristics of the valve, in the case of changing the inlet pressure, to maintain the outlet pressure and temperature values ??listening within a certain range. Valve pneumatic control valve is a necessary accessory, the main role is to pressure air supply pressure and stabilizes to a constant value, in order to adjust the valve to obtain a stable source of power for air conditioning control. Form of the structure can be divided into film, spring diaphragm, piston, lever type and bellows; the number of seats can be artificially by single-seat and two-seater type; by valve position can be divided into positive-acting and reaction type. By the use of the media can be divided into steam valve, air valve, gas valve, and other applications such as some brands of solenoid valves and cylinders can be achieved without lubrication (lubricated by grease to achieve functional), it does not require the use of oil mist! Filtration degree usually 50-75μm, pressure range for 0.5-10Mpa, For filtration accuracy of 5-10μm, 10-20μm, 25-40μm, and the regulator is 0.05-0.3Mpa, 0.05-1Mpa Big Three ductless components are connected together is called the FRL. The Big Three are most indispensable pneumatic system gas supply, gas equipment installed in the vicinity, was the last to ensure the air quality. Installed in accordance with the order of the Big Three were air intake direction filter, regulator and lubricator. Air filter and regulator together can be called pneumatic FRL. Also the air filter and valve assembly can be fitted together, they become a filter regulator (functions and air filter and valve used in conjunction with the same). Some applications can not allow the presence of oil mist in compressed air, you need to use compressed air in the oil mist separator filter out oil mist. In short, these elements can be selected according to need, and they can be used in combination. The air filter for cleaning the gas source, the compressed air may be filtered water, to avoid water entering with the gas means. Pressure relief valve on the gas source can be regulated, so that the gas source in a constant state, can reduce damage to the valve or actuator hardware when the gas supply pressure due to mutations. Filters for cleaning of the air can be filtered compressed air in the water to prevent water entering the system with the gas. Lubricator can lubricate the moving parts of the body, can be inconvenient to add oil to lubricate the parts, greatly extending the life of the body.
