Abstract
The invention discloses a high flow water stream switch, which comprises a body, a proximity switch and a magnetic floater; the body comprises an inlet, an outlet, an inner housing, an outer housing, a first cavity and a second cavity; the inlet is located at the lower end of the body; the outlet is located at the upper end of the body; the inner housing separates the first cavity from the second one; a plurality of first through holes are arranged in the middle of the inner housing; the magnetic floater can be movably placed in the second cavity, and the inlet is closed; and the proximity switch is mounted on the outer surface of the outer housing and is located on the upper section of the outer housing. The high flow water stream switch has high sensitivity, accurate and reliable action, and high water flow.
Description
Technical field
The present invention relates to the water flow switch field, particularly relate to the water flow switch that water control equipment such as a kind of water heater are used.
Background technology
Water flow switch is also claimed flow switch or flow sensor; Be that boiler water circulation control, Inlet and outlet water control, the water that is used for electric heater, solar water heater, air conditioner and other water systems adds processes such as thermal control, pump switch control, the control of electromagnetically operated valve break-make or water outlet outage, water outlet energising control, after reaching certain flow, current converted into the senser element of the switching regulator signal of telecommunication.Existing water flow switch mainly comprises polytypes such as gravity type, magnetic-type, baffle-type, piston type.
The power of lifting that makes progress when wherein the operation principle of gravity type water flow switch is water flows is lifted a magnetic spool approaching and is driven dry reed switch and produces signal, and the advantage of this water flow switch mainly contains highly sensitive, is not easy the changing of the relative positions and does.But it is less than normal that existing gravity type water flow switch generally has flow, the defective that resistance is too big.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of great deal running water switch, and discharge is big, and proper is reliable.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of great deal running water switch is provided, comprises: body, near quick closing valve and magnetic float; Said body comprises import, outlet, inner housing, shell body, first cavity and second cavity; Said import is positioned at the body lower end, and outlet is positioned at the body upper end, and said inner housing is separated first cavity and second cavity; There are some first through holes at said inner housing middle part; Said magnetic float is positioned in second cavity movably, and with import sealing, saidly is installed on the outer surface of said shell body and is positioned at the epimere of shell body near quick closing valve.
In preferred embodiment of the present invention, said shell body outer surface has a groove, saidly is embedded in the groove near switch.
In preferred embodiment of the present invention, said first through hole has more than four.
In preferred embodiment of the present invention, there is one second through hole said inner housing upper end.
The invention has the beneficial effects as follows: great deal running water switch of the present invention, highly sensitive, proper is reliable, and discharge is big.
Description of drawings
Fig. 1 is the structural representation of great deal running water switch one preferred embodiment of the present invention;
Sketch map when Fig. 2 is the water inlet of great deal running water switch shown in Figure 1;
The mark of each parts is following in the accompanying drawing: 11 are import, and 12 are outlet, and 13 is shell body, and 14 is inner housing, and 141 is first through hole, and 142 is second through hole, and 15 is first cavity, and 16 is second cavity, and 2 is near switch, and 3 is magnetic float.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of great deal running water switch; Comprise: body (mark), near quick closing valve 2 and magnetic float 3, said body comprises import 11, outlet 12, inner housing 13, shell body 14, first cavity 15 and second cavity 16, said import 11 is positioned at shell body 13 lower ends; Outlet 12 is positioned at shell body 13 upper ends; Said inner housing 14 is separated first cavity 15 and second cavity 16, and there are some first through holes 141 at said inner housing 14 middle parts, and said first cavity 13 is communicated with outlet 12; Said second cavity 14 is communicated with import 11; Said magnetic float 3 is positioned in second cavity 14 movably, and with import 11 sealing, saidly is installed on the outer surface of said shell body 14 and is positioned at the epimere of shell body 14 near quick closing valve 2.
Fixing for ease of near switch 2, said shell body 14 outer surfaces can have a groove, and said being embedded in the groove near switch 2 installed and fixed.
For increasing water flow, said first through hole 141 preferably has more than four.
The copper magnetic float 3 of magnetic float 3 preferred employings, promptly magnet coats copper material outward; Said inner housing 13 upper ends also have one second through hole.
In conjunction with illustrated in figures 1 and 2; The course of work of great deal running water switch of the present invention is following: with great deal running water switch of the present invention import outlet upright installation upwards downwards; During water flowing (shown in protruding): have water to get into from import 11, water from bottom to top pushes up built-in magnetic float 3 to second cavity, 16 upper ends, thereby shake-up goes out switching signal near switch 2 so sensing; Water flows into first cavity 15 through first through hole 141 from second cavity 16 simultaneously, flows out from exporting 12 at last; When cutting off the water supply (as shown in Figure 1): magnetic float 3 will fall after rise under action of gravity; Thereby reset near switch 2; Sensing goes out switching signal once more, just can realize the effect of water cut-off protection or switch motor through the time relay or control board according to these switching signals.
Great deal running water switch of the present invention, highly sensitive, proper is reliable, and discharge is big.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
