Specific embodiment
Below in conjunction with the accompanying drawing in the invention embodiment, the technical scheme in the invention embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of the invention rather than whole
Embodiment.Based on the embodiment in the invention, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of the invention protection, in the case of not conflicting, the invention
In embodiment and the feature in embodiment can be mutually combined.
Elaborate a lot of details in the following description in order to fully understand the invention, but present invention wound
Make and can also be different from alternate manner described here to implement using other, those skilled in the art can be without prejudice to this
Similar popularization is done, therefore the invention is not limited by following public specific embodiment in the case of bright creation intension.
Secondly, the invention is described in detail with reference to schematic diagram, when describing the invention embodiment in detail, for ease of
Illustrate, represent that the profile of device structure can be disobeyed general ratio and be made partial enlargement, and described schematic diagram is example, its
Here should not limit the scope of the invention protection.Additionally, the three-dimensional of length, width and height should be comprised in actual fabrication
Bulk.
In the description of the invention it is to be understood that term " " center ", " longitudinal ", " horizontal ", " on ", D score,
The orientation of instruction such as "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward " or position relationship are
Based on orientation shown in the drawings or position relationship, it is for only for ease of description the invention and simplifies description, rather than instruction
Or the hint device of indication or element must have specific orientation, with specific azimuth configuration and operation, be not therefore understood that
It is the restriction to the invention.Additionally, term " first ", " second " etc. are only used for describing purpose, and it is not intended that indicating
Or hint relative importance or the implicit quantity indicating indicated technical characteristic.Thus, " first ", " second " etc. are defined
Feature can express or implicitly include one or more this feature.In the description of the invention, unless separately
It is described, " multiple " are meant that two or more.
In the description of the invention, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", " being connected ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or integratedly
Connect；Can be to be mechanically connected or electrically connect；Can be to be joined directly together it is also possible to be indirectly connected to by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning in the invention for the term.
As shown in figure 1, the invention includes main valve 1, pilot valve 2 and current induction apparatuss 3, described pilot valve 2 controls master
The unlatching of valve 1, the water inlet A of described pilot valve 2 is connected with the inlet pipeline of described main valve 1 by branch road A, described pilot valve 2
Water outlet A be connected with current induction apparatuss 3, described current induction apparatuss 3 are connected with control relay 4,
Described branch road A passes through the upper lid of main valve 1 to connect with pilot valve 2.Described branch road A be provided with pressure gauge, filter and
Minor valve A.
The water outlet B of described current induction apparatuss 3 is connected with the outlet pipeline of described main valve 1 by branch road B, described branch road B
It is provided with minor valve B.
