Abstract

The utility model relates to an anti-siphoning device of an inlet valve, comprising an intake pipe, an intake main body and a raising bar. The utility model is characterized in that the top end of the intake pipe is provided with an oriented flake, a water stop rubber pad and an anti-siphoning rubber pad. The oriented flake is provided with an inlet channel and an outlet channel which are not communicated with each other. The inlet channel is communicated with the intake pipe; the water stop rubber pad is arranged at the exit of the inlet channel while the anti-siphoning rubber pad is covered at the upper end of the oriented flake. The novel anti-siphoning device of an inlet valve of the utility model greatly improves the anti-siphoning and anti-backflow ability of the inlet valve; furthermore, the suitability range of the inlet valve in the water tank can be increased.

Description

A kind of anti-siphon means of water intaking valve

Technical field

The utility model relates to a kind of anti-siphon means of water intaking valve, is specially adapted to the anti-siphon and the anti counter-flowing of tank intake valve of water.

Background technology

Existing tank intake valve of water differs in anti-siphon, anti counter-flowing function quality, and what have does not possess anti-siphon function; Have because unreasonable structure, only establish an anti-siphon pad simply at the water inlet pipe mouth place, anti-siphonage is low, the requirement that can't be up to state standards.

The utility model content

The utility model is intended to propose a kind of water intaking valve anti-siphon means simple in structure, can prevent the siphon and the refluence of water tank effectively, thereby keeps the health of resource of water supply.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of anti-siphon means of water intaking valve, contain water inlet pipe, water inlet body and arguing for the sake of arguing, and it is characterized in that: the water inlet pipe top is provided with splitter, sealing rubber cushion and anti-siphon rubber cushion; Splitter is provided with mutual disconnected inlet channel and water outlet water channel, and inlet channel is communicated with water inlet pipe; The sealing rubber cushion is located at the inlet channel outlet, and anti-siphon rubber cushion covers in the splitter upper end.

For increasing anti counter-flowing ability of the present utility model, the utility model also is being provided with unidirectional water conservancy diversion film between splitter lower end and water inlet pipe top.

When water intaking valve was in into the water state, the sealing rubber cushion moved on being argued for the sake of arguing and lifting, and current are through water inlet pipe, and the inlet channel on the splitter will prevent that the siphon film is whole and upwards pass, and flowed out through the water outlet water channel to enter water tank again, finished into water process.When supply channel owing to cut off the water supply, and in the water tank during fills with water, can form vacuum to a certain degree this moment in the water inlet pipe, therefore sealing rubber cushion and anti-siphon rubber cushion are had the power of inhaling down, thereby make the sealing rubber cushion be adjacent to inlet channel, anti-siphon rubber cushion is adjacent to splitter; Anti-siphon rubber cushion has completely cut off inlet channel and water outlet water channel, thereby has prevented that the water in the water tank is inhaled into water inlet pipe under the effect of atmospheric pressure, thereby pollutes resource of water supply.

The beneficial effects of the utility model are: science simple in structure, and can prevent siphon and refluence with extremely proving effective, thus avoid resource of water supply contaminated.

Among the figure: 1. keg float group body, 2. the water inlet body is 3. argued for the sake of arguing, 4. on cover, 5. go up rubber cushion, 6. loam cake, 7. anti-siphon rubber cushion, 8. splitter, 8a. inlet channel, 8b. water outlet water channel, 9. water inlet pipe, 10. unidirectional water conservancy diversion film, 11. sealing rubber cushions, 12. sealing mats.

The specific embodiment mode

Below in conjunction with accompanying drawing and present embodiment the utility model is further specified.

As shown in Figure 3, each parts of the utility model are formed whole water inlet body 2 after the socket successively, and Fig. 1 is the assembly drawing of the utility model and keg float group body 1.As Fig. 1, Fig. 3 and shown in Figure 4, when water intaking valve is opened and be in into the water state, move on the sealing rubber cushion 11, current are through the inlet channel 8a of water inlet on the splitter 8 jet flow that makes progress, to prevent the 7 whole upwards passing of siphon rubber cushion, and make anti-siphon rubber cushion 7 tightening seals live in to build 6 air inlet port, make current not from the outside seepage of this mouth, at this moment, loam cake 6, the cavity of an anti-siphon rubber cushion 7 and a relative sealing of unidirectional water conservancy diversion film 10 formation, most of current flow into water tank through water outlet water channel 8b and elastic one-way water conservancy diversion film 10, and the fraction current are shunted through water supplement port as required, thereby finish a injecting process.

As Fig. 1, Fig. 3 and shown in Figure 5, when water tank fills with water and water inlet pipe form a vacuum owing to cutting off the water supply, this moment, sealing rubber cushion 11 and anti-siphon rubber cushion 7 fell naturally, sealing rubber cushion 11 is sealed inlet channel 8a, anti-siphon rubber cushion 7 is close to splitter 8, makes the isolated unidirectional water conservancy diversion film 10 of inlet channel 8a and water outlet water channel 8b also be close to splitter 8.Water inlet pipe forms a vacuum owing to cutting off the water supply, make that the subsides of sealing rubber cushion 11 and anti-siphon rubber cushion 7 are tightr entirely, thereby prevented that effectively the interior water of water tank is because atmospheric effect siphon and refluence, flow into water inlet pipe through water outlet water channel 8b and inlet channel 8a, thereby the phenomenon of avoiding polluting resource of water supply takes place.The utility model is simple in structure, designs ingenious science, has promoted anti-siphon, the anti counter-flowing ability of water intaking valve greatly, makes the suitability scope of water intaking valve in water tank increase.
