Solenoid valve is an industrial equipment controlled by electromagnetism. It is an automatic basic component used to control fluid. It belongs to actuator. Pneumatic solenoid valve is one of them. It blocks or leaks different oil drain holes by controlling the movement of valve body. The oil inlet hole is normally open, and hydraulic oil will enter different oil drain pipes, Then the oil pressure of the pneumatic solenoid valve pushes the piston of the oil cylinder. In this way, the mechanical movement of the whole solenoid valve is controlled by controlling the current of the electromagnet of the pneumatic solenoid valve.

With China's accession to the WTO, the auto parts produced by Guihang Group have been recognized by many foreign automakers in recent years. The auto parts export prospects of the Group are increasingly promising.
This year, U.S. GM, South Korea’s Daewoo and other multinational companies have indicated that they will purchase 2 billion yuan and 1 billion yuan worth of auto parts in China. At present, U.S. General Motors is in active contact with Guihang Group. Both parties may have electrical switches and radiators. Other aspects of cooperation.
According to reports, China's auto parts and export tariffs continue to decline, lower labor costs and energy costs, as well as the military employees of a good quality of staff, so that Guihang Group has a larger spare parts production and export advantages. The analysis of the competitiveness of 60 key auto parts and components products by national authorities showed that 33 kinds of parts and components in our country are highly competitive products, mainly material-intensive and labor-intensive products, accounting for approximately 20% of the total vehicle manufacturing cost. %, including radiators, sealants, etc. These are the advantages of the Guihang Group.
It is understood that the product positioning and market positioning ideas of Guihang Group's export products are as follows: 1. The main target of product users should be large automobile manufacturers; 2. The use of opportunities for the introduction of domestic models to enter the international market for similar models. Since China's imported Santana, Jetta, Citroen and other models also have production in Brazil, Germany, France, Spain and other countries, in the context of global integration of procurement, Guihang Group is working hard in this direction and has achieved certain benefits. Third, seize a certain type of vehicle in the foreign market into a recession, the output is relatively small, foreign supporting manufacturers do not want to match the opportunity to enter the international market and maintenance market, such as the Beverly ZX sedan, which has gradually withdrawn in France, Spain The mainstream market, and its supporting manufacturers have gradually lost interest, and now the Guihang Group is organizing back sales.
It is reported that this year, the export volume of Guihang Group's auto parts will increase significantly, and it is expected that by 2005, its auto parts exports will reach 20 million US dollars.
It can work normally under vacuum, negative pressure and zero pressure, but its diameter is generally less than 25 mm.
It can also operate under zero pressure difference, vacuum and high pressure, but it has high power and must be installed horizontally.
The upper limit of fluid pressure range is high, which can be installed arbitrarily (need to be customized), but the condition of fluid pressure difference must be met.
Principle editing voice
There is a closed cavity in the pneumatic solenoid valve, and there are through holes in different positions. Each hole of the pneumatic solenoid valve leads to different gas pipes. There is a valve in the middle of the cavity and two electromagnets on both sides. The valve body will be attracted to which side when the magnet coil is electrified;
The pneumatic solenoid valve blocks or leaks different exhaust holes by controlling the movement of the valve body, and the air inlet is normally open. High pressure gas will enter different exhaust pipes, and then push the piston of the cylinder through the air pressure of the pneumatic solenoid valve. In this way, the mechanical movement of the whole solenoid valve is controlled by controlling the current of the electromagnet of the pneumatic solenoid valve.
Operation principle of pneumatic solenoid valve
We said the pneumatic solenoid valve working position (solenoid valve on or off), in fact, refers to the pneumatic solenoid valve spool position.
