Description
Technical field
The present invention relates to a kind of sensors, and the invention further relates to a kind of water pumps.
Background technology
Water flow switch is one kind of fluid switch, 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, available for electric heater, solar water heater, air conditioner and other water
Water loop control, disengaging water management, water computer heating control, pump switch control, the control of solenoid valve break-make or the water outlet power-off of system,
The processes such as water outlet power control.Amount (flow, that is, liquid flow dynamic pressure for whether flowing and flowing to liquid in signal piping
Power) whether reach requirement, while the state of the break-make by switch electric contact output (offer) signal.Device systems are by detection
There are no signal or control electric current from this switch by (the switching state of water flow switch electric contact), to judge pipe-line system
Working condition provides corresponding control or the method for operation or measure；Following monitoring function can be achieved：Media flow, reduction/raising
Flow velocity；Medium in the presence/absence of；Media flow/static；Monitoring pipeline inner fluid speed size, cutout monitoring prevent pump
Idle running.
Its primary structure of water flow switch is that the magnet that can be moved with water (flow) direction is equipped in water flow switch cavity, in water
Stream switch cavity sets the tongue tube that can be triggered by magnet in vitro.Water flow switch entrance is flowed through in current, promotes magnet movement, magnet
Tongue tube action is triggered, tongue tube sends signal, whether controlling electric motor starting.
There are following defects for existing water flow switch：1st, the action of magnet needs certain stroke and time, therefore not enough
It is sensitive；2nd, cannot work in the environment of having magnetic field, because extraneous magnetic field can cause the malfunction of water flow switch；3rd, need compared with
Big initial kinetic energy could promote magnet to move, and such as the water flow switch is used in water pump, in the course of work of water pump weep
In, water flow switch akinesia；4th, tongue tube is fragile, and in addition water flow switch is integrally located in the pump housing, is not easy to tie up after damage
Repair replacement；5th, it can not be applied in the water environment for having impurity, easily be blocked, adsorb and stuck by impurity in the passage of magnet sliding；6、
Electric property insulation is poor, and security can not ensure.In conclusion traditional water flow switch can be further improved.
Check-valves refers to flow in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and main function is to prevent medium from falling
It flows, prevent pump and drive motor reversion and vessel media from releasing.
The check-valves used in existing water pump, is typically mounted in water inlet, and structure includes being provided with the valve seat of valve port, wears
The valve rod that can be slid on valve seat and up and down is located at, one end of valve rod is connected with to block the valve block of valve port, and valve block is located at valve seat
Lower section, being also arranged on valve rod makes valve rod holding move up so that valve block blocks the spring of valve port trend.When having, current are normal
By water inlet, the impulse force of current understands ejection valve block, and valve block and valve rod can overcome the elastic force of spring, is slided towards the direction for opening valve port
It moving, valve port is opened at this time, and current are entered by valve port in the pump housing, is finally flowed out from the outlet of the pump housing, when motor no longer works, water
Stream is no longer flowed into from water inlet, and valve rod can under the action of the spring, and band moving valve plate blocks the movement of valve port direction, prevents current from falling
Stream.
This check-valves thereon only there are one one-way cock structure, water pump at work, because under many environment, water pump is drawn up
The water come with many impurity, if the keying position for having impurity to be deposited in valve, may result in entire one-way cock and close not
Sternly, at this moment entire one-way cock does not just have closing function, and pumping in vivo water can flow backwards from check-valve port and damage impeller and electricity
Machine.And pumping in vivo diversion can be lost in, and self-suction function can be lost without diversion, self priming pump in the self priming pump pump housing.Water pump cannot
Normal use.In addition check-valves is when valve port is opened, and is fully open state, is not blocked at valve port, water pump at work, one
A little harder impurity can collide the impeller of motor as finger stone can enter via check-valves in the pump housing with current, serious to make
Impeller failure.
As an improvement, the applicant discloses a kind of new sensor application in water pump, Application No. is seen
The Chinese utility model patent application of ZL201520361776.6 discloses《Photoelectricity fluid sensor and the water with the sensor
Pump》(Authorization Notice No. CN204739310), the patent use photoelectricity water flow sensing unit, should using goods of furniture for display rather than for use formula structure come shading
Used in the water inlet end of water pump, the check-valves application of water pump is also used as, and ensures the situation that water flow is opened in gross area
Under, flow is from loss.But the transmitting light in the patent and reception light are in current, and long-time service will certainly generate
Many incrustation scales can influence the sensitivity and accuracy of sensor, it is therefore desirable to for further study to be used for a long time with improving this
Stability and reliability.
