Description

Drainage screen

Technical field

This utility model belongs to pipeline valve field, particularly relates to a kind of drainage screen.

Background technology

Drainage screen, is processed by the tinsel silk screen of different meshes, and it act as the impurity in filter medium. Particularly in, in some strainer valves, the impurity in water being filtered. Chinese patent CN204176074 discloses a kind of Novel filtration valve, the drainage screen of this Novel filtration valve is cylindrical, and sidewall is provided with uniform meshes, and the medium runner being perpendicular to strainer valve is installed, the top of drainage screen is adjacent to medium runner inwall, or stretches in the link slot on medium runner. Drainage screen offers opening corresponding to medium runner inlet side, but its upper opening portion also exists little area wire side. Thus under the extruding of daily dismounting and the effect washed away of medium, overthe openings wire side easily deforms, snap in medium runner upper wall, cause that drainage screen is difficult to dismantle.

Utility model content

For the problems referred to above, this utility model provides the drainage screen of a kind of simple in construction, convenient disassembly.

To achieve these goals, this utility model is by the following technical solutions: a kind of drainage screen, including dictyosome, described dictyosome includes the filter house being placed in medium runner and the connecting portion being positioned at filter house bottom, described filter house correspondence medium entrance side offers the medium entrance for passing through for impurity, and this medium entrance top is gap structure.

Further, described medium entrance is U-shaped structure so that drainage screen correspondence medium entrance side opening is relatively big, strengthens filter efficiency.

Further, described medium entrance upper width is less than described dictyosome diameter, so that be absent from vacant gap between the contact internal walls face of drainage screen and filter pipe, impurity flows in drainage screen each through Media Interface Connector and is filtered, it is ensured that filter quality.

Further, only filter house is hollow mesh structure, connecting portion can be entity structure, connecting portion need to be held when drainage screen is replaced, after drainage screen is extracted, connecting portion entity structure arrange make its structure more firm, unloading process is unlikely to deform, load is effective, dismantles more convenient. And filter house can directly be formed by one piece of solid material local hollow out, reduces manufacturing step, saves man-hour and cost.

Further, described dictyosome is cylindrically shaped.

In sum, the beneficial effects of the utility model are: this filter screen structure is simple, and medium entrance top is gap structure so that medium entrance top is absent from wire side, will not deform, snap in the situation of medium runner upper wall, it is ensured that the convenient disassembly in use procedure.

Fig. 2 is the structural representation of another kind of embodiment of the present utility model.

Detailed description of the invention

In order to make those skilled in the art be better understood from this utility model scheme, below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear, complete description.

As it is shown in figure 1, a kind of drainage screen, including dictyosome 1, described dictyosome 1 includes the filter house 11 being placed in medium runner and the connecting portion 12 being positioned at filter house 11 bottom. In use, filter house 11 is placed in the medium runner of strainer valve, and connecting portion 12 stretches out the bottom of strainer valve, with can collect filter screen filtration after the container of impurity that falls be connected. Dictyosome is cylindrically shaped, naturally it is also possible to be adapt to other shapes that valve body filters. Dictyosome 1 entirety can be hollow out dictyosome and arrange, and the filter house 11 of dictyosome offers the medium entrance 2 for passing through for impurity, and the corresponding inlet side at medium in its position, the wire side of the opposite side of dictyosome 1 is closure state, is absent from opening. When the filter house 11 of drainage screen is inserted in filter pipe, the inside of dictyosome 1 top and filter pipe is adjacent to, medium is flowed into by the medium entrance 2 of described filter house 11 sidewall when flowing, the sidewall of opposite side flows out, owing to opposite side sidewall is absent from opening, impurity is just blocked, and reaches the effect filtered.

Concrete, the top of medium entrance 2 is that breach is arranged so that the top of medium entrance is absent from wire side, is in that in the connection use procedure of filter pipe, medium entrance top wire side will not be occurred to deform under medium washes away and the situation at Snap joint place, thus convenient disassembly. When being shaped as body of strainer valve, it is possible to medium entrance 2 is shaped to U-shaped so that the area of opening reaches maximum, increased efficiency. Further, in order to ensure that filter quality, the width of the upper notch of the medium entrance 2 of drainage screen should limit to some extent, the width of its breach should less than the diameter of described dictyosome 1, so when drainage screen is after inserting filter pipe, and will not there is vacant gap between filter pipe because opening is excessive, medium all can be filtered by drainage screen.

As preferably, as in figure 2 it is shown, the connecting portion 12 of drainage screen can be set to solid material, and further, the filter house 11 of drainage screen can be that this kind of solid material local hollow out forms, back wall set formation drainage screen, the entity part of bottom becomes connecting portion 12. So make two parts directly to be formed by a block of material, it is not necessary to carry out the connection of two kinds of materials, save material, and reduce manufacturing step, save man-hour and cost. So arrange reason be because need to hold connecting portion when drainage screen is replaced, after drainage screen is extracted, comparatively soft when connecting portion dictyosome is arranged, it is easy to deform because of stress. Being arranged by the entity structure of connecting portion makes its structure more firm, is unlikely to deform in unloading process, and load is effective, dismantles more convenient.

Obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, all should belong to the scope of this utility model protection.
