The main features of the solenoid valve

The main features of the solenoid valve (1) leakage block, internal leakage easy to control, the use of safety. Internal and external leaks are elements that endanger safety. Other self-control valve stem usually stick out by the electric, pneumatic, hydraulic actuator control spool rotation or movement. This must solve the long-term movement of the valve stem seal leakage problems; only the electromagnetic valve is the role of electromagnetic force sealed in the electric control valve magnetic sleeve complete iron core, there is no dynamic seal, so easy to block leakage . Electric valve torque control is not easy, prone to internal leakage, and even pulled off the stem head; structure of the solenoid valve easy to control the internal leakage until it drops to zero. Therefore, the use of special safety solenoid valve, especially for corrosive, toxic or high temperature medium. (2) The system is simple, then the computer, low prices Qian. Solenoid valve itself is simple, the price is low, compared to other types of actuators such as regulating valve easy to install and maintain. Even more remarkable is the composition of the control system is much simpler, the price is much lower. As the solenoid valve is the switch signal control, and industrial computer connection is very convenient. In today's popularization of computers, the price plummeted era, the advantages of the solenoid valve even more pronounced. (3) action express delivery, power is small, lightweight appearance. Solenoid valve response time can be as short as a few milliseconds, even the pilot solenoid valve can be controlled within a few tens of milliseconds. Since the self loop, more responsive than other self-controlled valves. Well-designed solenoid valve coil power consumption is very low, is an energy-saving products; can also be done only trigger action, automatically maintain the valve position, usually do not consume electricity. Solenoid valve small size, saving space, but also lightweight and beautiful. (4) regulation accuracy is limited, the applicable medium is limited. Solenoid valve usually only switch two states, the spool can only be in two extreme positions, can not be adjusted continuously (trying to break a lot of new ideas, but are still in the trial stage of the trial) so the regulation accuracy is subject to certain restrictions. Solenoid valve on the media have a higher cleanliness requirements, including granular media can not be applied, in the case of impurities must be filtered out. In addition, viscous media can not be applied, and the range of viscosities for specific products is relatively narrow. (5) Model variety, wide range of uses. Despite the inherent lack of solenoid valve, the advantages are still very prominent, so it is designed into a wide range of products to meet a variety of different needs, a very wide range of uses. Solenoid valve technology is also progress around how to overcome the inherent deficiencies, how to better play its inherent advantages and expand.

Refers to the addition of a small amount of its solution can make the interface state of the material changes significantly. With a fixed hydrophilic lipophilic group, in the surface of the solution can be aligned. The molecular structure of the Surfactant is amphiphilic: one end is a hydrophilic group and the other end is a hydrophobic group; the hydrophilic group is often a polar group such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amine and Its salts, hydroxyl groups, amide groups, ether bonds and the like can also be used as polar hydrophilic groups; and hydrophobic groups are often non-polar hydrocarbon chains, such as 8 carbon atoms above the hydrocarbon chain. Surfactants are divided into ionic surfactants (including cationic surfactants and anionic surfactants), nonionic surfactants, amphoteric surfactants, complex surfactants, other surfactants and the like.
