Description
Technical field
Water pump water flow switch technical field is the utility model is related to, refers in particular to a kind of water pump Water flow switch structure.
Background technology
Water pump is the device that current are transported in a kind of rotation by motor, and automatic pump refers to that current are automatically controlled
Water pump.To realize automatically controlling for water pump, pressure switch typically is installed in the delivery port of the pump housing, it is with being arranged at water inlet pipe
Check-valves interoperation together, plays the effect stopped automatically.Such as in the case of weep, it there are flowing out, pump startup, but because
Current output is small, and manifold pressure moment can be made to become big, and motor is shut down at once, and weep continues to flow out, and makes pump startup again, so
Circulation causes the frequent starting of pump, not only electric power has been wasted, and motor easily causes damage.
The content of the invention
The utility model is compact-sized in view of the above-mentioned problems, provide one kind, effectively solves pump motor frequent starting
Water pump Water flow switch structure.
What the purpose of this utility model was realized in：
A kind of water pump Water flow switch structure, including the pump housing and water flow switch, water inlet and delivery port are offered on the pump housing, is gone out

The water flow switch is connected by passage one with the delivery port of the pump housing, and sensor component is connected with the passage two, sensing
Magnetic induction switch is connected with device part, non-return valve seat, the lower end of non-return valve seat and passage are additionally provided with the water flow switch
One forms sealing.
In above-mentioned water pump Water flow switch structure, the upper end of the non-return valve seat extends upward one section of cylindrical sleeve, circle
Check-valve spring is provided with the outer wall of column sleeve, one end of check-valve spring is against the upper surface of non-return valve seat, and the other end is against
On the lower surface of sensor component.
In above-mentioned water pump Water flow switch structure, copper ring is additionally provided with the passage one and non-return valve seat sealing.
In above-mentioned water pump Water flow switch structure, the non-return valve seat bottom has a notched water impact
Portion.
In above-mentioned water pump Water flow switch structure, the side of the water flow switch is further opened with passage three, in passage three
It is connected with pressure sensor.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
Water flow switch of the present utility model is realized pair by the induction between sensor component and non-return valve seat
Whether water pump is turned on or off, avoid due to traditional mechanical water pump formula open and caused by motor frequently open and close caused by electricity
Power wastes and the situation of motor damage.

Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
A kind of water pump Water flow switch structure, including the pump housing 1 and water flow switch 2, water inlet 1a is offered on the pump housing 1 and is gone out
Mouth of a river 1b, delivery port 1b are located at the upper end of the pump housing 1, and the water flow switch 2 has the 2a of the passage one and 2b of passage two, the passage one
2a and the 2b mutual conductions of passage two, the water flow switch 2 are connected by the 2a of passage one with the delivery port 1b of the pump housing 1, described logical
Sensor component 2d is connected with the 2b of road two, magnetic induction switch 2e is connected with sensor component 2d, is gone back in the water flow switch 2
Non-return valve seat 2c is provided with, non-return valve seat 2c lower end is formed with the 2a of passage one to be sealed.
In above-mentioned water pump Water flow switch structure, the upper end of the non-return valve seat 2c extends upward one section of cylindrical sleeve
2f, check-valve spring 2g is provided with cylindrical sleeve 2f outer wall, check-valve spring 2g one end is against non-return valve seat 2c upper end
Face, the other end are against on sensor component 2d lower surface.
In above-mentioned water pump Water flow switch structure, copper ring is additionally provided with the 2a of passage one and non-return valve seat the 2c sealings
2h。
In above-mentioned water pump Water flow switch structure, the non-return valve seat 2c bottoms have a notched water impact
Portion 2i.
In above-mentioned water pump Water flow switch structure, the side of the water flow switch 2 is further opened with passage three, in passage three
It is connected with pressure sensor 3.
Operation principle of the present utility model：Water enters in the pump housing 1 from water inlet, when the water in the pump housing 1 is to non-return valve seat 2c
When producing pressure, motion is close to magnetic induction switch 2e upwards by non-return valve seat 2c, when between non-return valve seat 2c and magnetic induction switch 2e
Distance reach a timing, the motor of water pump just starts start-up operation, when water inlet 1a fashionable, the pump housings 1 slowly that do not have water to enter
When insufficient pressure is so that non-return valve seat 2c to be pressed off caused by interior water, non-return valve seat 2c just under check-valve spring 2g driving back
The distance between motion, such non-return valve seat 2c and magnetic induction switch 2e just become closer to original state, and motor will close
Close, water pump is stopped.
