Massage solenoid valve
Massage electromagnetic valve, using the principle of ventilation and discouraged, achieve the effect of massage.
Using the two position three way structure, there are three general put together, the five put together, put together products, electricity can be ventilation, power through a gas, can be used for air pressure 30KPa, pressure is 0.03mpa work, product belongs to a normally closed, meaning long time is power off general electric, only to pass.
The 1 principle:
Product inlet nozzle inlet, through product internal, internal can be made into closed, also can be made into ventilation, when we need the gas from the air outlet hole massage electromagnetic valve, then only need to give products electricity, blocking the products of stomatal suction rod downward moving, gas can pass from the air outlet hole, after the power and plug the.
Two internal front said product can be made into closed and ventilation, the need to look at the needs of customers, when made into a closed type, product power without gas discharge, when made into ventilation type, can exhaust outlet.
Fig. 2 Schematic principle of the product:
Inside a closed type massage solenoid valve:
The internal ventilation type massage solenoid valve:
Characteristics of 3 product gas:
Use of media: can be used for all gases, because the internal material used for making corrosion resistant materials.
Pressure load: can be used for the pressure of the product is the use of 30KPa, if you need to apply to the pressure bigger, need to redesign the product power and internal structure.
Air tightness: as shown above, massage the solenoid valve is energized, A mouth can not be in the product of long-term ventilation in case of gas leakage, when energized, C mouth can not leak.
4 electrical parameters:
Voltage: can be selected from among 6-220V, products usually adopts DC power.
Power: according to customer's electricity rate set, electricity rate is the ratio of the product on and power-off time. Electricity rate higher products, only small electricity power, the lower the rate of product, power can be bigger.
Current: current due to the power customer, so need to show that massage solenoid valve under the same power, the higher the voltage products, current will be smaller, so when the customer power supply circuit current load is lower, attention must be paid to the current problem of product.
Pressure resistant products: 1000V, 1MA current, 1 minutes without breakdown.
Other parameters of 5 products:
Corrosion resistance: the internal use of plastic, metal, rubber materials, anti-corrosion effect, when using some corrosive medium, no problem.
Products related to the rate of temperature rise: electric temperature rise and product that is powered on for a long time, the need of power design is powered on for a long time, that will not lead to excessive temperature rise of burnt products. If the general is not a long time electricity power, product temperature rise no higher than 65 degrees celsius.
Insulation resistance: massage solenoid valve used in some household products, so the product must do a good job in the insulation, the insulation resistance in the European 50M this product.
