Abstract
The utility model discloses an automatically air supplying check valve for pneumatic water tanks, which comprises a main check valve body (1), and is characterized in that the check valve also comprises an inhalation valve (2) which is arranged on the outside wall of the main check valve body (1), the main body (1) is provided inside with a main body air inlet (7); one end of the main body air inlet (7) is communicated with an inhalation valve air inlet (6), and the other end is communicated with a water inlet cavity (8); the main body air inlet (7) and the inhalation valve air inlet (6) are positioned on the same axial line. The utility model not only can automatically supply air as water is flowing in, improves the sealing performance while without the leakage phenomenon, and plays the role of saving water, increases pressure and is beneficial to environmental protection; but also is convenient to repair.
Description
Technical field
The utility model relates to a kind of safety check, belongs to a kind of automatic tonifying Qi safety check that is used for pneumatic storage tank.
Background technique
Air valve and safety check on the Pneumatic water flushing cistern of use in toilet, all be equipped with at present, its effect is in when water inlet, by the moisturizing of safety check feed tank, by air valve with in the air inlet box, keep air-stable in the case, and the effect by hydraulic pressure makes water tank have strong bath power energetically, but because the valve of this split-type structural makes Pneumatic water flushing cistern after using certain hour, air in the case runs off, have a strong impact on bath pressure, must usually lean on artificial supplementation, very inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can tonifying Qi automatically again in water inlet, and can prevent the automatic tonifying Qi safety check that is used for pneumatic storage tank of the interior aqueous reflux of water tank.
The purpose of this utility model is to realize like this, comprise check valve body, also comprise the Aspirating valves on the outer wall that is installed in main body, be provided with the main body inlet hole in the main body, main body inlet hole one end is connected with the Aspirating valves inlet hole, the main body inlet hole the other end is connected with water-inlet cavity, and main body inlet hole and Aspirating valves inlet hole are same axis.
The utility model is because safety check and Aspirating valves are designed to integrative-structure, not only can tonifying Qi automatically again in water inlet, and sealing improves, and water leakage phenomenon can not occur, plays water saving supercharging and environmentally friendly effect, and is convenient to keep in repair.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation
Below in conjunction with accompanying drawing the utility model is further specified.
Embodiment
With reference to Fig. 1, present embodiment is made up of check valve body 1 and the Aspirating valves 2 that is installed on the outer wall of main body 1.Main body 1 one ends have water-inlet cavity 8, main body 1 the other end is equipped with check valve 10, water-inlet cavity 8 is connected by the water channel of establishing in the main body 9 with check valve 10, be provided with the main body inlet hole 7 perpendicular in the main body 1 with water channel 9, main body inlet hole 7 one ends are connected with the inlet hole 6 of Aspirating valves 2, and main body inlet hole 7 the other ends are connected with water-inlet cavity 8 by water channel 9.Main body inlet hole 7 is same axis with the inlet hole 6 of Aspirating valves.The diameter of described water-inlet cavity 8 is greater than the diameter of water channel 9.Aspirating valves 2 is to have the pore that valve 3, valve 3 are housed in a lid, the lid to face toward the perforate of lid, anti-water seal 4 is housed on the valve 3, in the lid chamber of valve 3 belows spring 5 is housed, one end of spring 5 withstands on valve 3 bottoms, the other end of spring 5 withstands on main body inlet hole 7 end faces, and lid is threaded with main body 1.Joint at above-mentioned critical piece is equipped with seal ring.Working procedure of the present utility model: main body one end that check valve will be housed is contained on the water tank, and the water-inlet cavity of check valve body and water source are connected, and when water tank need be intake, check valve was opened automatically, and water enters water tank by water-inlet cavity by water channel, check valve.Aspirating valves replenishes air automatically simultaneously, and extraneous air enters water tank by the suction port of Aspirating valves through main body inlet hole, water channel, keeps air-stable in the case.After water tank was filled water, check valve was closed automatically, and water is entered by water channel in the shock mount chamber of Aspirating valves by water-inlet cavity, and after being full of by water in its chamber, Aspirating valves cuts out automatically.Owing on the valve of Aspirating valves anti-water seal is housed, therefore water leakage phenomenon can occur.
