Description
Technical field
The utility model is related to a kind of photoelectricity fluid switch, is mainly used in water pump.
Background technology
Water flow switch is one kind of fluid switch, and it is that one kind is being incited somebody to action after certain flow is reached by taking water flow sensing unit as an example
Current are converted to the senser element of switching regulator electric signal, can be used for electric heater, solar water heater, air-conditioner and other water
The water circulation of system is controlled, turnover water management, water computer heating control, pump switch are controlled, magnetic valve break-make is controlled or water outlet is powered off,
The processes such as water outlet power control.Amount (flow, that is, liquid flow dynamic pressure for whether being flowed to liquid in signal piping and being flowed
Power) whether requirement is reached, while by switch electric contact output (offer) state for the break-make of signal.Device systems are by detection
There are no signal or control electric current to judge pipe-line system by (the switching state of water flow switch electric contact) from this switch
Working condition, provides corresponding control or the method for operation or measure；It is capable of achieving following monitoring function：Media flow, reduces/improves
Flow velocity；Medium in the presence/absence of；Media flow/static；Monitoring pipeline inner fluid speed size, cutout monitoring prevent pump
Idle running.
Check-valves, using relatively common, refers to be flowed in itself by medium and automatic open and close flap, for preventing in water pump
The valve that only medium flows backwards, also known as non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, its
Main Function is to prevent medium from flowing backwards, prevent pump and drive motor from inverting, and vessel media is released.
Water pump operationally, because under many environment, the water that water pump is pumped, it carries many impurity, if there is impurity to pile up
In the keying position of valve, may result in whole one-way cock and fit badly, at this moment whole one-way cock does not just have closing function,
Water in the pump housing can flow backwards from check-valve port and damage impeller and motor.And the diversion in the pump housing can be lost in, the self priming pump pump housing
Interior no diversion, self priming pump can lose self-suction function.Water pump can not be used normally.Check-valves has been when valve port is opened in addition
Full open state, does not block at valve port, and operationally, some harder impurity, such as finger stone can be with current via only for water pump
Return valve and enter the impeller that motor can be collided in the pump housing, serious meeting makes impeller failure.
How check-valves to be combined with water flow switch, so that both can play each self-applying and installation volume subtracts significantly again
It is small, it is that those skilled in the art need to make research.
