Abstract
The invention discloses a self-adaptive throttling faucet which is used for opening or closing water tail end flow of a water supply network. The self-adaptive throttling faucet mainly comprises a fixed sleeve (1), a spring (2), a sliding sleeve (3), a resistance cone (4) and a faucet (8). The self-adaptive throttling faucet has the main advantages that under the action of water pressure within a preset range, the faucet automatically maintains a stable outflow, so that throttling and water conservation are achieved.
Description
Technical field
The present invention relates to a kind of Water saving tap, specifically a kind of adaptive throttling water tap is comprised of throttle mechanism and water tap.The open and close of the terminal flow of water supply pipe network water.
Background technique
Water tap is widely used in the water end of water supply network, serves the huge numbers of families in town and country, and according to " Code for design of building water supply and sewerage " (GB50015-2003), when effect hydraulic pressure was 0.05MPa, the specified outflow of water tap was 9 liters/min.But in fact act on hydraulic pressure and far surpass 0.05MPa, most of more than 0.2MPa, take 0.2MPa as example, when using ordinary faucet, outflow reach 14 liters/more than the min, amplification reaches more than 44%, increase with hydraulic pressure, well beyond code requirement, in use the super stream of this superpressure will cause very large waste.Not only in this, water tap One's name is legion in the water supply network, the maximum reason of aggravating just short water supply at the super stream of superpressure of water use peak period.
Water saving has become worldwide topic, the outflow of requirements of the times water tap should have more scientific standard, take the water tap of bore DN15mm as example, the optimum flow of generally acknowledging is 6～8 liters/min, for this reason, water tap with throttling action should be kept optimum flow in the situation that superpressure may occur, and in the situation that does not have superpressure can not affect normal use.
Summary of the invention
The objective of the invention is provides a kind of adaptive throttling water tap in order to reach throttling and water-saving.
The technological scheme that the present invention solves the problems of the technologies described above is:
A kind of adaptive throttling water tap comprises water tap, is provided with throttle mechanism in the adaptive throttling water tap, and throttle mechanism is positioned at the import of adaptive throttling water tap, and throttle mechanism is made of fixed muffle, spring, sliding sleeve and resistance cone.
1. the structure of each parts:
Fixed muffle is that the penetrating cylinder in two ends, an end are that water intake, the other end are water outlet, and its inwall is provided with limited ring or the limiting stopper of a circle projection;
Sliding sleeve is that an end is the penetrating cylinder of horn-like enlarging;
The resistance cone is bullet shape, and the axis vertical cross-section of cone is less than sliding sleeve axis vertical cross-section;
2) annexation of each parts:
Sliding sleeve inserts in the fixed muffle, an end of horn-like enlarging and water intake homonymy; Spring housing is outside sliding sleeve, between the horn-like enlarging of fixed muffle limited ring and sliding sleeve; The resistance cone inserts in the water outlet of fixed muffle, and conehead is relative with the outflow opening of sliding sleeve, and the cone bottom is provided with support and fixed muffle is fixedly connected.
Above-mentioned spring is various types of Compress Springs.
The purposes of adaptive throttling water tap,
1) the terminal flow of water supply network water control.
2) other feedwater have the overcurrent occasion of flow control requirement, and the overcurrent occasion of flow control requirement is arranged such as shower, flushing valve etc.
3) the overcurrent occasion that other fluids that flow control requires are arranged beyond dewatering.
Throttle mechanism of the present invention characteristics compared with prior art are:
1. have stable outflow under the Water Pressure in prespecified range, take the water tap of bore DN15mm as example, under the Water Pressure of 0.02～0.5MPa, outflow maintains in the scope of 6～8 liters/min;
2. runner is smooth and easy, and passing ability is good, is difficult for stopping up.Take the water tap of bore DN15mm as example, can be the solid of d ≯ 4mm smoothly by diameter;
3. production technology is simple, and component all adopt moulding and stamping part, and are with low cost.
Accompanying drawing is described
Fig. 1 is the structural representation of the present invention when opening.
Fig. 2 is the structural representation of the present invention when closing.
Among Fig. 1 and Fig. 2: fixed muffle 1, spring 2, sliding sleeve 3, resistance cone 4, limited ring 5, water intake 6, water outlet 7, water tap 8.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
One. structure of the present invention:
Structure of the present invention is provided with throttle mechanism in the adaptive throttling water tap as shown in Figure 1, and throttle mechanism is positioned at the import of adaptive throttling water tap, and throttle mechanism is made of fixed muffle 1, spring 2, sliding sleeve 3 and resistance cone 4.
1. the structure of each parts:
Fixed muffle 1 is that the penetrating cylinder in two ends, an end are that water intake 6, the other end are water outlet 7, and its inwall is provided with the limited ring 5 of a circle projection;
Sliding sleeve 3 is that an end is the penetrating cylinder of horn-like enlarging;
Resistance cone 4 is bullet shape, and the axis vertical cross-section of cone is less than sliding sleeve 3 axis vertical cross-sections;
2) annexation of each parts:
Sliding sleeve 3 inserts in the fixed muffle 1, an end of horn-like enlarging and water intake 6 homonymies; Spring 2 is enclosed within outside the sliding sleeve 3, between the horn-like enlarging of fixed muffle limited ring 5 and sliding sleeve 3; Resistance cone 4 inserts in the water outlet 7 of fixed muffle 1, and conehead is relative with the outflow opening of sliding sleeve 3, and the cone bottom is provided with support and fixed muffle 1 is fixedly connected.
Two. use the present invention:
When water tap 8 is opened as shown in Figure 1, water enters throttle mechanism, flow through water intake 6, sliding sleeve 3, resistance cone 4 and water outlet 7, then flow out from water tap 8 outlets, flow section area minimum between resistance cone 4 and sliding sleeve 3 outlets, resistance to water-flow is also just maximum, high rear low differential water pressures (by water (flow) direction) before this forms, act on respectively on the upstream face and back side of sliding sleeve 3, the size of this pressure reduction is directly proportional with the size of effect hydraulic pressure.Be used as when using hydraulic pressure greater than minimum setting value, under the thrust that differential water pressures produces, sliding sleeve 3 Compress Springs 2 are in axial sliding along water (flow) direction, the cone head part of resistance cone 4 is inserted in the outflow opening, making the port of sliding sleeve 3 and the flow section area between the resistance cone 4 is that the flow-out hole open area reduces, thereby reaches the throttling purpose, and effect hydraulic pressure is larger, the axial displacement of sliding sleeve 3 is just larger, and the flow-out hole open area is also just corresponding little; Effect hydraulic pressure is from large to small the time, corresponding the diminishing of thrust that differential water pressures produces, when less than the elastic force of spring 2, spring 2 promote sliding sleeves 3 against the current flow path direction be in axial sliding, the flow-out hole open area is changed from small to big; Along with the effect size variation of hydraulic pressure in prespecified range, under the elastic force of thrust that differential water pressures produces and spring 2 interacted, sliding sleeve 3 is corresponding back and forth to endwisely slip, and in time adjusts the discharge orifice open area, guarantees stablizing of outflow.
Be used as when using hydraulic pressure less than minimum setting value, throttle mechanism is failure to actuate, and does not affect the normal use of water tap 8.
As shown in Figure 2, when water tap 8 was closed, current stopped when water tap 8 was closed, the differential water pressures that acts on the sliding sleeve 3 disappears, sliding sleeve 3 resets under spring 2 promotes, and outflow opening recovers original good passing capacity, and larger solid is passed through in the opening process of next time smoothly.
