Detailed description of the invention
Below by combine the drawings and specific embodiments technical scheme is done into
One step describes in detail.
As shown in Figure 1 and Figure 4, a kind of gravity type current inductive switch that the present invention provides,
It is mainly used on water treatment facilities, is typically mounted at the water inlet of water treatment facilities,
By gathering the water-flow signal of water inlet, the device controlled on water treatment facilities is opened automatically
Open, it is achieved the intelligent automation of water treatment facilities.This gravity type current inductive switch includes
A piece housing 10, is plugged on the flow-limiting valve 20 of housing 10 one end, is located in housing 10
Baffle ring 30 and the ball between baffle ring 30 and flow-limiting valve 20 40.On housing 10
Being provided with interface 12, interface 12 can dock with the water pipe on water treatment facilities, installs
Very convenient.
Baffle ring 30 and housing 10 design for integral type, and baffle ring 30 is positioned in housing 10
Position, portion, the inner surface of baffle ring 30 and housing 10 is formed and seals, current merely by
The endoporus 31 of baffle ring 30 circulates.
As shown in Figures 2 and 3, flow-limiting valve 20 is plugged on one end of housing 10, current limliting
Valve 20 includes a connecting column 23, and the outer peripheral face of connecting column 23 is evenly equipped with some blades
21, when blade 21 is provided with cascaded surface, flow-limiting valve 20 and housing 10 grafting, cascaded surface
It is close on the opening surface of housing 10, plays the effect of support, stretch into housing 10 internal
Blade 21 part, the inner surface of its outer surface and housing 10 is close to, such setting
Make between adjacent blades 21 formed a runner, on whole flow-limiting valve 20 annularly-distributed have many
Individual runner, the current flowed out through this gravity type current inductive switch are more uniformly distributed.
A blind hole 22, the opening of blind hole 22 and baffle ring it is provided with in the inside of connecting column 23
Relatively, blind hole 22 is built with ball 40, and ball includes magnetic material for the endoporus 31 of 30
Main body, under normal circumstances, ball 40 is shelved on baffle plate under gravity, ball
The diameter of 40, more than the diameter of baffle ring 30 endoporus 31, so makes ball 40 and baffle ring
Define sealing between 30, out-of-date when there being water to flow through, ball 40 under the promotion of current,
Being retracted in blind hole 22, current enter into hydrotreater through baffle ring 30, flow-limiting valve 20
Other devices in.Further, the blind hole 22 in connecting column 23 is arranged to reducing
Shape, the i.e. inside diameter of blind hole 22, more than the diameter of blind hole 22 oral area, so make rolling
Pearl 40 is not easy to be stuck in being retracted into blind hole 22.Further, baffle ring 30 sets
Having inclined-plane, inclined-plane is gathered to ball 40, and the runner of whole baffle ring 30 is funnel-form, makes
The water flow impact pressure that is subject to of baffle ring 30 is little.
The ball 40 of the present invention uses magnetic material to make, on the outer surface of housing 10
Being circular projection 11 integrally formed with truncation surface, protruding 11 inside are provided with installing hole,
Magnetic-inductive device is installed in installing hole, opens through the sensing of this gravity type current when there being current
Guan Shi, the position of ball 40 changes, and arranges magnetic-inductive device on the housing 10
Capture this change, be converted to signal and be sent in the control system of hydrotreater, real
Existing intelligent automation work.
