Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses connecting portion department at the air valve sets up the filter screen, and foreign matter gets into the air valve when can preventing to have the foreign matter under the circumstances such as unusual in the pipeline, does benefit to the use of air valve.
Drawings
Fig. 1 is a view showing a structure of an air valve with a screen.
Fig. 2 is a diagram illustrating the structure of the filter screen of fig. 1.
Fig. 3 is an enlarged view of S in fig. 1.
In the figure, 11 main body parts, 12 connecting parts, 13 flanges, 2 filter screens, 21 columnar parts, 22 top covers, 23 convex edges, 31 observation holes, 32 transparent covers, 4 positioning bolts, 5 pipeline connecting pipes and 51 pipeline connecting pipe flanges.
Detailed Description
Example 1
Referring to fig. 1 to 3, the air valve with the filter screen comprises a housing, wherein the housing is provided with a main body part 11, a connecting part 12 is arranged at the bottom of the main body part 11, a flange 13 is arranged at the bottom of the connecting part 12, and the filter screen 2 is arranged at the connecting part 12.
Because the filter screen is arranged at the inlet of the air valve, foreign matters cannot enter the air valve under the condition that the foreign matters exist in the pipeline, and the use of the valve is facilitated.
The filter screen sets up the form more, in this embodiment, flange 13 inboard bottom sets up heavy groove, filter screen 2 has column portion 21, column portion 21 top sets up top cap 22, column portion 21 bottom sets up protruding edge 23, protruding edge 23 passes through the connecting piece and is connected with heavy groove.
The column part, the top cover and the convex edge of the filter screen can be all net-shaped bodies, or the column part and the top cover can be net-shaped parts, and the convex edge is in a plate-shaped form.
The sink is provided with an upper mounting hole with threads, a lower mounting hole is formed in a flange (pipeline connecting pipe flange) at the pipeline connecting pipe, the upper mounting hole and the lower mounting hole are matched to form a mounting hole, and a positioning bolt 4 for fixing the filter screen is arranged at the mounting hole.
During the installation, at first pack the filter screen into connecting portion, the protruding edge of filter screen is located heavy groove department, and the pilot bolt is installed at last mounting hole department (fixed filter screen), and the valve body (the flange of valve body and the flange of takeover are counterpointed) falls for the mounting hole under the head of pilot bolt is packed into, through the mode above-mentioned, can fix the filter screen on the one hand, and on the other hand, two pilot bolts (are located left side and right side respectively) form spacing the installation that also does benefit to the flange.
Since the improved point is the inlet part of the air valve housing (valve body), the explanation of other structures is omitted, and reference can be made to the prior art.
Example 2
The basic structure is the same as that of embodiment 1, except that, referring to fig. 1, an observation hole 31 is arranged on the connecting part 12, a transparent cover 32 is arranged at the entrance of the observation hole 31, the transparent cover is made of glass or transparent plastic, and the transparent cover is in threaded connection with the entrance of the observation hole. The observation hole 31 is obliquely arranged, and an inlet is upward, so that the observation hole is convenient to check.
The filter screen can be checked through the observation hole, and the maintenance is convenient. Since the cover of the observation hole is in a transparent form, on one hand, the observation is convenient; on the other hand, the foreign matter is prevented from falling into the observation hole after the disassembly.
Above only do the preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above embodiment, all belong to the technical scheme of the present invention all belong to the protection scope of the present invention. For those skilled in the art, several modifications can be made without departing from the principle of the present invention, and such modifications should also be considered as the protection scope of the present invention.
