Our oxygen equipment, etc. in the emergency cut-off of the valve of the turbo expander imported film. Four-way flange solenoid valve  in our production applications, which works as fo llows: when the current through the coil, produce excitation and fixed core pull the moving core, the moving core driven sliding spool and compress the spring, change the position of the sliding spool, thus changing the direction of the fluid. When the circuit is power, according to the * spring will promote sliding spool, top back to the moving core, so that the flow of fluid according to the original direction. Oxygen production, zeolite switching system to force the valve switch is two four-way solenoid valve to control airflow for to force the valve piston at both ends. To force the single coil solenoid valve  to control the opening and closing.

Solenoid valve failure will directly affect the action of the switching valve and control valve solenoid valve does not move, a common fault, the following aspects should investigation: (1) of the solenoid v alve lugs loose or thread off, the solenoid valve may not power, can be tight solid thread. (2) solenoid valve coil burned, you can remove the solenoid valve wiring measured with a multimeter, if open, the solenoid valve coil burned. Causes the coil, moisture, caused by bad insulation magnetic flux leakage, resulting in the coil current is too large and burned, so to prevent rainwater from entering the solenoid valve. In addition, excellent spring, the reaction force is too large, too few coil turns, the suction can not make the coil burnt. Emergency treatment manual button on the coil by the normal working hours, "0" bit hit "1" bit, making the valve is opened. (3) solenoid valve stuck. Solenoid valve slide valve sleeve and spool with a small gap (less than 0.008mm), are generally single assembly, mechanical impurities into or too little lubricant, it is easy to get stuck. Hold into the treatment methods available wire from the head holes to make it boun ce. The fundamental solution To remove the single coil solenoid valve, remove the spool and spool cover, with CCI4 cleaning, making the spool in the valve kit flexible movement. Demolition should pay attention to the various components of the assembly sequence and the external wiring position for re-assembly and wiring is correct, also check the oil mist injector holes are blocked, adequacy of lubricants. (4) leak. Cause leakage air pressure, making a forced valve opening and closing difficult, because the sealing gasket is damaged or slide valve wear caused by several cavity channeling gas. The failure of the solenoid valve switch system, select the appropriate time, the flange solenoid valve  in the loss of electricity for processing, in a never-ending within the gap is a switch will switch the system to pause, and calmly.

Introduction factory completion of a type solenoid valve thermal vacuum testing in the testing process should be tested single coil solenoid valve response character istics of the traditional volume of test equipment can not meet the transport needs and therefore need to be equipped with portable flange solenoid valve  test equipment. CompactPCI referred to as CPCI, Chinese, also known as Compact PCI PICMG Association in 1994 to a bus interface standard. It s dense rugged VME excellent cooling effect of packaging and large-scale equipment and PC cheap, easy to use the processing capacity of the chip together, both to ensure high reliability of 99.999%, greatly reducing the cost of hardware and software development . Its compact body, securely installed, and adapt to various transport conditions, and high reliability. Each functional board with the modular structure of the CPCI bus, the plug is very safe and convenient, particularly suitable for a variety of models of this system test objects and a variety of requirements of the test conditions.

The automatic control valve, solenoid valve and the other is the medium viscosity applies to a narrow range of air, water, steam, oil and media for the pilot solenoid valve and its structural parameters are different; generally are not common. ZDF multi-function shuttle valve  only use a small screw, but do generic of gas, water, oil, but also the viscosity of the oil the scope of application greatly widened, popular.

Often also want to use it both manually, as a standby when the power outage or failure. More shuttle valve  technical manual devi ce only to manually open the valve or manually off quick exhaust valve , two fully equipped known as the full manual. Manual device can be preset for the valve opening, generally manually only the maximum or minimum valve opening preset complete manual can be preset maximum or minimum opening. ZDF-solenoid valve is a completely manual class. Other models solenoid valve may be needed, with a simple manual device.

The proportion of fuel gas rising demand for gas solenoid valve is also growing. Gas, natural gas, industrial gas, city gas, liquefied petroleum gas, such as a good variety of impurities and corrosion varied, the requirements of the valve is not the same. Moreover, the difference between pressure levels, compressed natural gas as high as 21 ~ 25Mpa gas appliance pressure as low as 2Kpa. China were already mature product. This CE series gas solenoid valve has been exported to the European Union. It is worth mentioning that the dual-fuel vehicles in China with sound environmental regulations continue to spread to 12 cities have converted a few thousand cars, and now multi-selection of complete sets of imported fuel for the device, the shuttle valve  with the supporting imports. Fact, these solenoid valve is not foreign solenoid valve professional company production and performance test results are not all in compliance with the relevant technical standards of China s gas industry. The company already has a more reliable and more affordable dedicated quick exhaust valve  is gradually replacing imported electromagnetic valve.

We must first solve the problem of high temperature, sealing materials, conductive and magnetic materials should be selected in particular. Corrosion of the steam pipe is more powerful, to be taken seriously. More important is that there are a lot of condensate in the steam pipe in the factory after work, the shuttle valve  in the gaseous and liquid fluids through the action reliable, its delivery inspection Road have strict procedures. This company ZQDF-type solenoid valve, 92 years as a national new product, the well-user tests in recent years has launched a compact CC series of steamquick exhaust valve .
