A kind of water inlet device
1, technical field:
The utility model relates to a kind of water inlet device that is used for water storage container or retaining work tank body, especially for the water inlet device of cylinder of internal cavity of bowl washer or washing machine etc., belongs to the renovation technique of water storage container or the used water inlet device of retaining work tank body.
2, background technology:
At present, there are two problems in the used water inlet device of water storage container or retaining work tank body: the one, and water storage container or the inner and outer air pressure imbalance of work tank body when the different operating state, high-temperature steam in water storage container or the work tank body causes the dangerous of use because air pressure rising suddenly can cause the leakage of steam or water; The 2nd, under the situation of intake pressure disappearance, the phenomenon that flows backwards can appear in the water in water storage container or the work tank body, also is " siphon " phenomenon.Usually the water in the work tank body is the water that the muddiness of a lot of booties is arranged, and " siphon " phenomenon can cause has many middle instruments or water treatment facilities to damage or stop up between water system and water inlet pipe, and therefore machine also can not work or damage.
3, summary of the invention:
The purpose of this utility model is to consider the problems referred to above and provides that a kind of to avoid water storage container or work tank body inner and outer air pressure to occur when the different operating state uneven and avoid taking place the water inlet device of " siphon " phenomenon.The utility model makes the gas in atmosphere and the work tank body keep circulation, and when tank body air pressure raise, air-flow can part overflow from tank body, and when tank body air pressure descended, outside atmosphere can enter the work tank body; And under the situation of intake pressure disappearance, owing to be communicated with atmosphere, the water of tank body can not be communicated with water inlet pipe.
Structural representation of the present utility model as shown in Figure 1, it is provided with the body (1) of hollow cavity, and body (1) is provided with one or more water inlets (2) that communicate with water inlet pipe A, is provided with one or more delivery ports (3) that communicate with work tank body B and is provided with one or more gas outlets that communicates with atmosphere (4).
Above-mentioned water inlet (2) and gas outlet (4) are arranged on the top of body (1), and delivery port (3) is arranged on the bottom of body (1).
Above-mentioned body (1) includes loam cake (1A) and lower body (1B), delivery port (3) is arranged on lower body (1B), be provided with the dividing plate (1C) that its inner chamber is separated in the cavity of loam cake (1A), water inlet (2) is arranged on a side of loam cake (1A), and communicate with the separation cavity of one of them, gas outlet (4) are arranged on the opposite side of loam cake (1A), and communicate with another separation cavity, loam cake (1A) is packed in the top of lower body (1B), and the cavity of loam cake (1A) communicates with the cavity of lower body (1B).
The delivery port (3) of above-mentioned lower body (1B) locates to have made screw thread, and it is connected with work tank body B by screw thread.
The utility model is owing to adopting body to be provided with one or more water inlets that communicate with water inlet pipe, being provided with one or more delivery ports that communicate with work tank body B and the structure that is provided with one or more gas outlets that communicate with atmosphere, therefore, it makes the gas in atmosphere and the work tank body keep circulation, when tank body air pressure raises, air-flow can part overflow from tank body, when tank body air pressure descended, outside atmosphere can enter the work tank body; And under the situation of intake pressure disappearance, owing to be communicated with atmosphere, the water of tank body can not be communicated with water inlet pipe.Event can be avoided water storage container or work tank body the inner and outer air pressure imbalance to occur when the different operating state and avoid taking place " siphon " phenomenon.The utility model is that a kind of design is ingenious, function admirable, convenient and practical water inlet device.

5, the specific embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, it is provided with the body 1 of hollow cavity, and body 1 is provided with one or more water inlets 2 that communicate with water inlet pipe A, is provided with one or more delivery ports 3 that communicate with work tank body B and is provided with one or more gas outlets that communicates with atmosphere 4.
Above-mentioned water inlet 2 and gas outlet 4 are arranged on the top of body 1, and delivery port 3 is arranged on the bottom of body 1.
Above-mentioned body 1 includes loam cake 1A and lower body 1B, delivery port 3 is arranged on lower body 1B, be provided with the dividing plate 1C that its inner chamber is separated in the cavity of loam cake 1A, water inlet 2 is arranged on the side of loam cake 1A, and communicate with the separation cavity of one of them, gas outlet 4 is arranged on the opposite side of loam cake 1A, and communicates with another separation cavity, loam cake 1A is packed in the top of lower body 1B, and the cavity of loam cake 1A communicates with the cavity of lower body 1B.Delivery port 3 places of above-mentioned lower body 1B have made screw thread, and it is connected with work tank body B by screw thread.。
During the utility model operate as normal, water is introduced from water inlet pipe A, enter into water device body 1 from water inlet 2 in, enter work tank body B by the guiding of water inlet device from the delivery port 3 of logical tank body.When the air pressure in the work tank body B raises, because the delivery port 3 that communicates with work tank body B communicates with open to atmosphere gas outlet 4, so the part air-flow in the work tank body B is discharged from open to atmosphere gas outlet 4, make the air pressure in the tank body reduce, thereby avoided the high-temperature steam in the tank body to cause steam or water leakage, avoided high-temperature steam to reveal cause dangerous because air pressure rises suddenly; When the tank body internal gas pressure descended suddenly, extraneous air-flow can enter work tank body B from open to atmosphere gas outlet (4), made the inside and outside air pressure balance of work tank body B.
When extraneous hydraulic pressure lacks suddenly, stop such as running water suddenly, Shuitu among the water inlet pipe A so flows backwards, this moment is because the existence of open to atmosphere gas outlet 4, working water in the tank body can not flow backwards from water inlet pipe A, thereby avoid " siphon " phenomenon occurring, avoid many middle instrument or water treatment facilities between water system and water inlet pipe to damage or stop up, thereby avoid machine can not to work or damage because of stopping up because of " siphon " phenomenon causes.
