Abstract
The utility model relates to the fluid mechanical field, especially to an anti-counter flow flow-adjustable water-shoot organ, which consists of a sprinkler head, a nozzle, a one-way valve, a pipe section and a flow meter. The characteristic is that, the sprinkler head and the nozzle are made of transparent materials. To prevent the counter flow of water flow towards the suction inlet, the one-way valve is arranged on the pipe section of the suction inlet. To adjust the flow freely, a flow meter is arranged at the front end of the nozzle. The utility model has advantage of simple structure, visual working state, adjustable and anti-counter flow, thereby having a good promoting and applying value.
Description
Technical field
The utility model relates to field of fluid machinery, refers in particular to a kind of anti-backflow flow adjustable type water sprayer.
Background technology
At present, water sprayer is extensive use of at water treatment field.Its operation principle is that water under high pressure is pressed in the nozzle of water sprayer, water under high pressure sprays into the conical horn mouth of shower nozzle from nozzle, water under high pressure can form negative pressure in the nozzle place in the process of spraying, mix with water thereby suction gas or liquid enter water sprayer, reach the purpose that liquid-liquid mixes or liquid one gas mixes.Because the water sprayer of prior art all is opaque, so in use existing deficiency is, the liquid-liquid that is carried out in water sprayer by liquid or gas in the negative pressure inspiration water sprayer mixes or liquid one gas mixed process or mixed effect can not observe directly from the outside, the adjusting of flow simultaneously is also inconvenient, in addition owing to can't observe inner duty from the outside, in use be easy to cause water under high pressure to the phenomenon that suction inlet flows backwards, bring a lot of inconveniences to the user.
Summary of the invention
For fear of with overcome above-mentioned deficiency, the purpose of this utility model provides a kind of simple in structure, easy to use, internal work situation and can regulate arbitrarily from visual observation, flow, and be provided with the visual anti-backflow flow adjustable type water sprayer that prevents counterflow unit.
Visual anti-backflow flow adjustable type water sprayer mainly comprises: shower nozzle, nozzle, check valve, tube coupling, flowmeter.It is characterized in that, adopt material transparent working nozzle and shower nozzle,, on the tube coupling of suction inlet, check valve is set,, flowmeter is set at spray nozzle front end in order to regulate flow arbitrarily in order to prevent the refluence of current direction suction inlet.
Can regulate by flowmeter according to the needs of flow, in use just can clearly observe the flow regime of current in water sprayer inside from the outside, be convenient to observe at any time liquid flow and check clogging, owing on tube coupling, check valve is set, can prevent suck-back in addition at suction inlet.
The utility model has the advantages that: simple in structure, duty is visual, adjustable, prevent characteristics such as refluence, thereby have good value for applications.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
As shown in the figure, number in the figure is represented respectively: 1. flowmeter 2. nozzles 3. shower nozzles 4. suction inlets 5. check valves 6. tube couplings.
The specific embodiment
As shown in Figure 1, flowmeter 1 is set, on the tube coupling 6 of suction inlet 4, check valve 5 is set, adopt material transparent working nozzle 2 and shower nozzle 1 simultaneously at nozzle 2 front ends.
During use, needs according to flow can be regulated by flowmeter 1, in use just can clearly observe the flow regime of current in water sprayer inside from the outside, be convenient to observe at any time liquid flow and check clogging, in addition owing on tube coupling 6, check valve 5 is set at suction inlet 4, can prevent suck-back, such as suck-back of agricultural chemicals etc.
