Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be further described below.
As shown in figure 1, the utility model provides a breather valve device for a filter, which comprises a cup cover 1, wherein the cup cover 1 is made of different materials, the cup cover 1 is made of transparent materials, the transparent cup cover 1 can visually observe the storage amount of liquid in the cup cover 1, the change of the storage amount of the liquid in the cup cover is observed after the breather valve 2 is closed, whether the airtightness of the breather valve 2 is good or not can be judged, if the breather valve 2 is in a closed state, the liquid in the cup cover runs off and evaporates, the airtightness of the breather valve 2 is indicated to be problematic and needs to be replaced, and if the cup cover 1 is made of opaque materials, the airtightness of the breather valve 2 can be judged to be good or not through independent detection. The top end face in the inside of cup cover 1 is provided with a breather valve 2, breather valve 2 includes an air outlet channel 21 that stretches out the top of cup cover 1, a serial communication port, breather valve 2 still includes a breather valve main part 22 that links to each other with air outlet channel 21 bottom, the inside of breather valve main part 22 is provided with holds chamber 221, hold the inside plastics floater 3 that is provided with of chamber 221, be provided with a step in the inside junction with air outlet channel 21 of breather valve main part 22, be provided with an O type circle 226 on the step, the diameter of O type circle 226 is less than the diameter of plastics floater 3, set up a plurality of inlet openings 224 along same horizontal position in the both sides of breather valve main part 22, be provided with a apopore 223 in the bottom of breather valve main part 22. In the specific use process, when the cup cover 1 is empty, the plastic floating ball 3 is positioned at the bottom of the accommodating cavity 221 of the breather valve main body 22, at the moment, the air outlet channel 21 is unblocked, when liquid enters the cup cover 1 of the filter, the original gas in the cup cover 1 is discharged through the air outlet channel 21, when the liquid continuously enters the cup cover 1, the liquid enters the accommodating cavity 221 of the breather valve main body 22 through a plurality of water inlet holes 224 on the side surface of the breather valve main body 22, at the moment, the hollow plastic floating ball 3 floats under the welfare action of the liquid until the hollow plastic floating ball contacts with the O-shaped ring 226, the liquid continuously enters, the pressure is increased, the sealing between the plastic floating ball 3 and the O-shaped ring 226 is tighter, when the liquid needs to be discharged, the liquid in the accommodating cavity 221 of the breather valve main body 22 is discharged through the water outlet hole 223 at the bottom of the breather valve main body 22, the hollow plastic floating ball 3 descends along with the action of the liquid under the action of gravity, air enters the breather valve 2 and the cup cover 1 through the air outlet channel 21, so that the effect of automatic air suction and air leakage of the cup cover 1 of the filter is realized.
The breather valve 2 is detachably arranged on the top end face of the cup cover 1, the breather valve 2 can be worn in the using process, if damaged, the breather valve needs to be replaced, and therefore the breather valve 2 is detachably arranged on the top end face of the cup cover 1.
This scheme adopts threaded connection's mode to connect cup cover 1 and breather valve 2, and is concrete, is equipped with a nut 11 at the top end face of cup cover 1, and the internal thread of nut 11 extends to the inside of cup cover 1, and the outside of outlet channel 21 is provided with the external screw thread, with the interior screw-thread fit of nut 11.
The supporting arm 12 is arranged on the top end face inside the cup cover 1 along the outer side of the internal thread to support the breather valve main body 22, the silica gel gasket 4 is arranged between the supporting arm 12 and the breather valve main body 22, the silica gel gasket 4 ensures that the air tightness between the breather valve 2 and the cup cover 1 is good, and the situations of air leakage and the like caused by the reasons of abrasion and the like at the matching position of the internal thread and the external thread are avoided, so that the breather valve 2 can be normally used.
The bottom of the breather valve main body 22 is provided with a bottom cover 222, the bottom cover 222 is provided with a water outlet 223, the hollow plastic floating ball 3 belongs to a component which is possibly damaged due to the characteristics of the material, such as damage, tightness damage and the like, and similar problems occur, the buoyancy of the plastic floating ball 3 can be influenced, so that the breather valve 2 can not be sealed, and the filter can not normally run, so that the filter needs to be replaced in time, but if the bottom of the breather valve main body 22 and the breather valve 2 are integrated, the whole breather valve 2 can only be replaced by replacing, the maintenance cost is increased undoubtedly, unnecessary waste is caused, the bottom cover 222 is arranged, the bottom cover 222 can be detached, the plastic floating ball 3 can be replaced independently, the maintenance cost is saved, resources are saved, the bottom cover 222 can be connected with the breather valve main body 22 in a plurality of ways, including threads, buckles and the like, bottom 222 is interference fit with breather valve main part 22 in this scheme, interference fit is a kind of tight fit, because at the in-process that uses, bottom 222 is located cup cover 1 inside with breather valve main part 22, maintenance all need pull down cup cover 1 at every turn, so more troublesome, if the connection between bottom 222 and breather valve main part 22 drops easily, this has increased cost of maintenance undoubtedly, so adopt the interference fit that is difficult for droing, reduce under satisfying the dismantlement condition and drop probably, cost of maintenance has been reduced.
The breather valve body 22 is made of nylon.
