Solenoid valve manufacturers take you to understand some industry knowledge

Solenoid valve manufacturers take you to understand some industry knowledge. This article will introduce in detail two three and two five intelligent toilet solenoid valve, pure dry knowledge!

1. Difference of gas path (or liquid path)

The two-position three-way intelligent toilet solenoid valve has an air inlet (connected to the air inlet pneumatic valve), an exhaust port (pneumatic valve for the entire target machine and equipment) and an exhaust port (usually equipped with a muffler, can not be installed without fear of noise).

The two-position five-way vacuum solenoid valve is equipped with an air inlet (connected with the air inlet pneumatic valve), a positive action exhaust port and a negative action exhaust port (respectively for the whole target machine and equipment of positive action and negative action pneumatic valve), a positive action exhaust port and a negative action exhaust port (assembled muffler).

2, motor control differences

Two-position three-way intelligent toilet solenoid valve is generally controlled by a single motor (i.e. single coil), two-position five-way miniature medical solenoid valve is generally controlled by a double motor (i.e. double coil). How much does the solenoid valve cost? The rated voltage of the coil is GENERALLY DC24V, AC220V, etc.

3. Detailed introduction of movement principle

3.1 two position three way solenoid valve

Time control solenoid valve is divided into two types: normally closed and on - off type. Normally closed means that when the coil is not energized, the gas circuit is disconnected; On-off type refers to the coil is not energized, the gas circuit connected.

Normally closed two three-way solenoid valve action principle: insert coil, connect the gas. Once the coil is powered off, the gas circuit will be disconnected, which is equivalent to "starting".

On and off two and three way single motor control of the vacuum solenoid valve operation principle: coil inserted, the gas disconnected, once the coil disconnected, the gas connected, that is, "start".

3.2. Two position five way vacuum solenoid valve

Two five-way double motor control intelligent toilet solenoid valve principle of action: when the positive action coil is inserted, the positive action air loop is connected (positive action air hole has air). How much does the solenoid valve cost? Even after the positive acting coil is disconnected, the positive acting air circuit remains connected until the reverse acting coil is inserted. When the reverse acting coil is inserted, the reverse acting air loop is connected (the reaction air hole has air). How much does the solenoid valve cost? Even after the reverse acting coil is powered off, the reverse acting air circuit remains connected until the positive acting coil is inserted. This is tantamount to "locking".

According to these characteristics of two five-way double motor control vacuum solenoid valve, in the design of mechanical and electrical engineering control circuit or customized PLC system, the vacuum solenoid valve coil can run 1 ~ 2 seconds, so that the vacuum solenoid valve coil can be maintained, not easy to damage.
