Description
Technical field
The utility model relates to a kind of selector valve, and more particularly, it relates to a kind of duplex filter selector valve.
Background technique
Bitubular return filter is a kind of for two-way switch filtering device, and it is exported to Vavle switching by Rotation With Changing.
At present, application number on market is that the Chinese patent of 201520148684.X discloses a kind of bitubular return filter, its drip irrigation device comprises housing, lid, selector valve and filter assemblies, two symmetrical projections are provided with above described lid, be formed with groove between two projections, the side of described projection opposed channels is plane, and described projection is all equipped with rotatingshaft, described projection and rotatingshaft are rotationally connected, and described projection is equipped with rotary locking mechanism.
And existing selector valve and such scheme similar, the flap semicolumn often that the valve rod of selector valve is communicated with, rotary valve rod, flap keeps off a side opening, and medium can only circulate from opposite side, then rotary valve rod, and flap blocks another opening; In this scheme, there is comparatively wide arc gap with coordinating of valve body in the flap of semicolumn, one surface is separated completely with valve interior wall, flap easily produces and departs from, therefore the coaxality of valve stem top and flap is lower, departs from aggravation after permanent, and sealing effect declines.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of duplex filter selector valve coordinating tightness higher.
For achieving the above object, the utility model provides following technological scheme: a kind of duplex filter selector valve, comprise valve body, the handwheel be arranged on valve body, the valve rod that links with hand wheel rotating, described valve body is provided with import, valve body both sides are provided with outlet, described valve rod is connected with the columned flap fitted tightly with valve interior wall, described flap is provided with the annular groove for medium circulation, described annular groove connects a side outlet of import and valve body, rotates the opposite side outlet that handwheel annular groove connects import and valve body.
Pass through technique scheme, when specifically using, its working principle is that medium flows through annular groove again from outlet outflow through entrance, and flap is complete round column structure, and itself and valve interior wall fit tightly, and turn to which direction all not coordinate space, when therefore ensure that lever operated and the coaxality of flap, avoid between flap and valve body and produce skew, reach higher tightness, improve overall structure serviceability.
The utility model is set to further: described annular groove outer rim is provided with flow guide structure.
Pass through technique scheme, flow guide structure i.e. intilted rounding, this structure make MEDIA FLOW stimulate the menstrual flow its edge time there is certain cushioning effect, active force is the power of all directions at its edge decomposition, the stress avoiding single direction is concentrated, avoid water hammering when connecting suddenly and larger impact is produced to annular groove, ensure that structural stability.
The utility model is set to further: described annular groove is opening minor arc structure outwardly.
By technique scheme, make the process of circulation of medium in annular groove very level and smooth, medium can realize smoothly turning in annular groove, decreases the impact force of medium.
The utility model is set to further: the groove depth of described annular groove near handwheel place is greater than its groove depth away from handwheel place.
By technique scheme, the inwall of annular groove defines inclined-plane, and thus during medium circulation, the impact force of medium can be divided into downward a part of component on inclined-plane, ensure that flap continues to compress valve interior wall downwards, improve cooperation tightness by this part component.
The utility model is set to further: described annular groove is arranged at flap shaft to middle part.
By technique scheme, during medium circulation annular groove, the masterpiece of annular groove carrying is used for, in the middle part of flap, being therefore equivalent to the fulcrum that active force acts on lever, it can't being caused to tilt to both sides, ensure that the stable of valve flap structure.

Embodiment
Referring to figs. 1 through Fig. 5, the utility model embodiment is described further.
A kind of duplex filter selector valve, comprise valve body 1, the handwheel 2 be arranged on valve body 1, with handwheel 2 rotate the valve rod 3 linked, valve body 1 is provided with import 4, valve body 1 both sides are provided with outlet 5, valve rod 3 is connected with the columned flap 6 fitted tightly with valve body 1 inwall, flap 6 is provided with the annular groove 7 for medium circulation, and annular groove 7 connects a side outlet 5 of import 4 and valve body 1, rotates the opposite side outlet 5 that handwheel 2 annular groove 7 connects import 4 and valve body 1; By such setting, when specifically using, its working principle is that medium flows through annular groove 7 through entrance and flows out from outlet 5, and flap 6 is complete round column structures, and itself and valve body 1 inwall fit tightly, and turn to which direction all not coordinate space, when therefore ensure that lever operated and the coaxality of flap 6, avoid to produce between flap 6 and valve body 1 and offset, reach higher tightness, improve overall structure serviceability.
As shown in Figure 2, annular groove 7 outer rim is provided with flow guide structure 8, flow guide structure 8 is intilted rounding namely, this structure make MEDIA FLOW stimulate the menstrual flow its edge time there is certain cushioning effect, active force is the power of all directions at its edge decomposition, the stress avoiding single direction is concentrated, and avoids water hammering when connecting suddenly and produces larger impact to annular groove 7, ensure that structural stability.
Embodiment as shown in Figures 3 and 4, annular groove 7 is opening minor arc structure outwardly; By such setting, make the process of circulation of medium in annular groove 7 very level and smooth, medium can realize smoothly turning in annular groove 7, decreases the impact force of medium.
Comparison diagram 4 and Fig. 5, the groove depth of annular groove 7 near handwheel 2 place is greater than its groove depth away from handwheel 2 place; By such setting, the inwall of annular groove 7 defines inclined-plane, and thus during medium circulation, the impact force of medium can be divided into downward a part of component on inclined-plane, ensure that flap 6 continues to compress valve body 1 inwall downwards, improve cooperation tightness by this part component.
Preferably, annular groove 7 is arranged at flap 6 axially middle part; By such setting, during medium circulation annular groove 7, the masterpiece that annular groove 7 carries is used for, in the middle part of flap 6, being therefore equivalent to the fulcrum that active force acts on lever, it can't being caused to tilt to both sides, ensure that the stable of flap 6 structure.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
