Abstract

The utility model discloses a water-saving hose, which comprises a pipe body, a plane surface, and a screw cap. A water-saving component is arranged on the plane surface, the water-saving component comprises a water-saving inner core, an O-shaped ring, and a water-saving outer sleeve, one end of the water-saving inner core is the plane surface, of which holes are formed along the circumferential direction, racks are arranged all over the body of the inner core, the O-shaped ring is sleeved at the other end of the inner core and erected on the teeth, the water-saving inner core is buckled on the water-saving outer sleeve, and the water outlet river closure area in the position of the rack of the water-saving inner core is less than that of a water inlet hole of the screw cap. The utility model has advantages that the pointless spillage of the water pressure is limited in the water using process, and the most legitimate using outflow and pressure are maintained. Due to only adopting thewater-saving outer sleeve, the water-saving inner core, the O-shaped ring, and the like members as the water-saving core pieces, the water-saving hose has simple structure, lower cost, and extensive applicability, and the structure can be used on any hoses.

Description

The water saving flexible pipe

Technical field

The utility model relates to a kind of flexible pipe, the particularly a kind of flexible pipe that can economize on water.

Background technique

The diameter of existing its whole pipe of flexible pipe is even, and water inlet place and water outlet place are not provided with the speed and the pressure loss that corresponding part reduces current, so turbulent flow, off-energy, reasonably water easily take place when mobile liquid.

The model utility content

Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of water saving flexible pipe is provided, and makes it keep reasonable flow, reduces the pressure loss.

The utility model solves the problems of the technologies described above the technological scheme that is adopted:

The water saving flexible pipe, comprise body, plane and nut, it is characterized in that: also be provided with the water saving assembly on the described plane, described water saving assembly comprises water saving inner core, O type circle, water saving overcoat, described water saving inner core one end is along the circumferential plane of perforate, inner core whole body cloth tooth bar, O type snare at the other end of inner core and frame on tooth, the water saving inner core is buckled in outside the water saving and puts, and the water outlet captured area at the tooth bar place of water saving inner core is less than the captured area of nut water inlet.

Compared with prior art, advantage of the present utility model is:

Utilize the hydraulic pressure shunting action of the profile of tooth space formation of water saving inner core, reach the effect of disperseing hydraulic pressure, thereby the profile of tooth water outlet captured area of water saving inner core changes the osculum sectional dimension less than the captured area of nut water inlet, the meaningless loss of hydraulic pressure in the water conservation process keeps the most rational use traffic and pressure.

Because only adopt parts such as water saving overcoat, water saving inner core, O type circle as the water saving core members, so structure is comparatively simple, cost is lower, and applicability is wide, can use on any flexible pipe.

Description of drawings

Fig. 1 is the utility model embodiment's a structural representation;

Fig. 2 is the plan view of Fig. 1.

Fig. 3 is the utility model embodiment's a explosive view.

Embodiment

Embodiment is further described the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, the water saving flexible pipe, comprise body, plane and nut, also be provided with the water saving assembly on the described plane, described water saving assembly comprises water saving inner core 10, O type circle 8, water saving overcoat 9, and described water saving inner core one end is the plane along circumferential perforate 12, inner core whole body cloth tooth, O type circle 8 is enclosed within the other end of inner core 10 and frame on tooth bar 11, and water saving inner core 10 is buckled on the water saving overcoat 9, and the water outlet captured area at the tooth bar place of water saving inner core is less than the captured area of nut water inlet.

General hose body mainly by nut 1, pad 2, metal flat 3, mould joint 4, metallic hose 5, interior pipe 6, cover 7 are formed, and see Fig. 1, Fig. 3; Also can form, but its joint part is generally nut and plane, pad by other.

On the above-mentioned water saving inner core 10 with descending profile of tooth 11, O type circle 8 is enclosed within on the water saving inner core 10, water saving overcoat 9, parts are combined into the water economizer core, the profile of tooth space of water saving inner core constitutes the water inlet, and the O type circle of described water saving overcoat 9 upper-end surfaces constitutes osculum with the profile of tooth slit of being located at water saving inner core outside.

The hydraulic pressure shunting that the profile of tooth space of above-mentioned water saving flexible pipe utilization water saving inner core forms, reach the effect of disperseing hydraulic pressure, thereby the profile of tooth water outlet captured area of the inner core of economizing on water then changes the osculum section area less than the captured area of nut water inlet, the meaningless loss of hydraulic pressure in the water conservation process keeps the most rational use traffic and pressure.Under hydraulic pressure 5BAR and caliber 6.0mm, peak rate of flow is not more than 19.8 liters/minute; After installing this water-saving valve additional, under hydraulic pressure 5BAR and caliber 6.0mm, peak rate of flow is not more than 13.2 liters/minute.

Claims

1, water saving flexible pipe, comprise body, plane and nut, it is characterized in that: also be provided with the water saving assembly on the described plane, described water saving assembly comprises water saving inner core, O type circle, water saving overcoat, described water saving inner core one end is along the circumferential plane of perforate, inner core whole body cloth tooth bar, O type snare at the other end of inner core and frame on tooth, the water saving inner core is buckled in outside the water saving and puts, and the water outlet captured area at the tooth bar place of water saving inner core is less than the captured area of nut water inlet.

2, water saving flexible pipe as claimed in claim 1 is characterized in that: on the described water saving inner core pad is set.
