Abstract
The utility model discloses two-position three-way valve, comprise valve body, valve body top embeds diaphragm tool bag, is fixed by the valve gap above valve body, be provided with seat below valve body, and seat and valve body are fixed by the clip interface below it and locking nut by seat.The utility model structure is simple, easy for installation; Control highly sensitive; Water (flow) direction can be switched fast, at utmost reduce and switch friction; By force corrosion-resistant, anti-aging excellence.
Description
Technical field
The utility model belongs to field of Environment Protection, is specifically related to a kind of two-position three-way valve for water treatment.
Background technique
When field of Environment Protection water treatment, need to use valve to control water body turnover.Three-way valve has an import, two outlets.After water body enters import, when inner spool is in diverse location, the outlet of outflow is different.Traditional three-way valve can meet most of production requirement, but still there is many defects.Such as, employing two spools of traditional three-way valve, when changing import and export position, need to change two valve element positions simultaneously, and in use once some spools damage, so must stop all process steps, and changing spool could continue; Secondly, the spool of traditional three-way valve is installed inconvenient, owing to there are two spools, need by its all fixing compact could work, once the installation of some spools is not firmly, whole valve working again will be obstructed; In addition, traditional three-way valve needs rotation two spools when switching current, improves and switches friction, may cause the loss that spool is certain.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of two-position three-way valve for water treatment.
Technological scheme: in order to reach foregoing invention object, the utility model is specifically achieved like this: two-position three-way valve, comprise valve body, valve body top embeds diaphragm tool bag, be fixed by the valve gap above valve body, be provided with seat below valve body, and seat and valve body are fixed by the clip interface below it and locking nut by seat.
Wherein, in order to improve sealing effect further, be filled with sealing plug and spring between described seat and clip interface, and spring is positioned on the downside of sealing plug.
Wherein, in order to improve sealing effect when switching current, between described valve body and seat, between spring (7) and clip interface, seal ring is provided with.
Wherein, the described diaphragm tool portion of wrapping is circular metal plate, and bottom is column barrier film, covers on valve body by circular metal plate; Described column barrier film top is two panels ellipse metal plate, and bottom is the metal bar of the securing circle of ellipse metal plate with filter core.
Wherein, described valve body has passage and one, the bottom vertical passage of 2 transverse directions.
In order to improve working life further, described valve body adopts PA material to make.
Beneficial effect: the utility model is compared with conventional art, and tool has the following advantages:
(1) structure is simple, easy for installation;
(2) control highly sensitive;
(3) water (flow) direction can be switched fast, at utmost reduce and switch friction;
(4) by force corrosion-resistant, anti-aging excellence.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Two-position three-way valve as shown in Figure 1, comprises the valve body 3 of a passage and bottom vertical passage of 2 transverse directions, and valve body 3 is PA material preferably; Valve body 3 top embeds diaphragm tool bag 2, described diaphragm tool bag 2 top is circular metal plate, bottom is column barrier film, cover on valve body 3 by circular metal plate, described column barrier film top is two panels ellipse metal plate, and bottom is the metal bar of the securing circle of ellipse metal plate with filter core; Diaphragm tool bag 2 is fixed by the valve gap 1 above valve body 3, is provided with seat 5 below valve body 3, and seat 5 and valve body 3 are fixed with locking nut 9 by the clip interface 8 below it by seat 5; Be filled with sealing plug 6 and spring 7 between described seat 5 and clip interface 8, and spring is positioned on the downside of sealing plug 6; Between described valve body 3 and seat 5, between spring 7 and clip interface 8, be provided with seal ring 4.
During specific works, diaphragm tool bag is switched to working state, namely the two panels ellipse metal plate of column barrier film is parallel with the crosspassage of valve body, and current form a water-flowing path from the m-crosspassage of crosspassage-two panels ellipse metal plate, flow; Work as end-of-job, when needing to carry out backwash to valve body, by two panels ellipse metal plate half-twist, form the water-flowing path of the whole side-vertical passage of crosspassage-ellipse metal plate, carry out backwash.
