Abstract
A constant-pressure constant-current valve comprises a valve base, a valve core, a spring and a baffle ring, wherein the valve base comprises chamber and its lower is contracted inwards to form a boss, the valve core has a T-shaped section with an outer flange at upper, the middle of the flange is provided with a central shaft extended downwards, the upper of the valve core is provided with a water inlet and the lower is provided with a throttle slot, the spring, valve core and baffle ring are provided in the valve base, the baffle ring is fixed with the valve base, the valve core and the valve base can slide relatively. When the valve core and the valve base slide relatively, the passage area of the throttle slot is changed. The utility model overcomes the defects of the prior art as low flow and pressure stability and hard installment, having high pressure and flow stability, strong installment adaptability and wide application in the domestic water-saving and water balance of central air conditioner technical fields and the like.
Description
Technical field
The utility model relates to a kind of plumbing, is specifically related to a kind ofly can adjust water flow and pressure automatically according to source pressure, provide the suitable regime flow and the device of saving water and energy of pressure for water.
Background technique
In the prior art, its prosperous board water economizer that the product with similar functions has the WQS water economizer of Korea S, KNT water economizer and domestic independent development to produce.The said goods all exists flow, pressure stability poor (Korea S's water economizer particularly, big with variation in water pressure by conical surface throttling, flow); In addition, the spool of its prosperous water economizer protrudes from outside the valve body, and the occasion that has is installed inconvenience.
Summary of the invention
The purpose of this utility model provides the constant-pressure constant-flow valve that a kind of constant pressure and flow is effective, wide adaptability is installed, not only can be used for life water saving, the waterpower autobalance is regulated, realized to the waterpower that also can be used for central air-conditioning system automatically, thereby save heat energy and keep ambient-temp-stable.
The technical solution of the utility model is: constant-pressure constant-flow valve comprises valve seat, spool, spring, back-up ring, it is characterized in that: described valve seat inside is formed with cavity and the formation boss is inwardly shunk in the bottom; The T-shaped cross section of spool, outward flange is arranged at top, and the flange middle part is formed with the central shaft that overhangs downwards, and described spool top has water intake, bottom that throttling groove is arranged; Spring, spool, back-up ring are installed in the valve seat successively, and back-up ring and valve seat are fixed, but spool and valve seat slide relative; When spool and valve seat slide relative, change the area of passage of throttling groove.
Locating flange that is suitable for embedded installation or screw thread, flange, tooth, the button that directly is connected with pipeline are arranged on the described valve seat.
Throttling groove on the described spool is the variable cross section groove.
The beneficial effects of the utility model are: overcome known technology flow, pressure stability difference and inconvenient defective is installed, provide a kind of pressure, discharge stability good, installation adaptability is good, and water-saving result is better and can be applicable to the automatic constant-pressure constant-flow valve of energy saving of system such as central air-conditioner.

Embodiment
Figure 1 shows that embodiment one of the present utility model, valve seat 1 is that outward flange is arranged at top, and the hollow member of inner convex platform is arranged at the bottom; Spool 2 is made up of the central shaft that flange and middle part overhang downwards.Porose 2-2 on the cup-shaped cavity, cavity wall of upward opening is arranged at spool top, and the trapezoidal throttling groove 2-1 that connects the lower end surface is arranged at the bottom, and positive stop lug boss is arranged on the central shaft; Spool is installed in the valve seat, and spring 4 acts between spool flange and the valve seat boss, and back-up ring 3 is fixed on valve seat top; But spool and valve seat slide relative.The space that forms between hole 2-2, spool and the valve seat on spool upper chamber and the wall thereof, the throttling groove on the spool constitute circulation passage.
Source pressure is during less than the Set pressure of spring, and constant-pressure constant-flow valve is in state shown in Figure 1, this moment throttling groove 2-1 the area of passage maximum, guarantee normal water under the low hydraulic pressure.When source pressure is higher than the spring Set pressure, spool 2 is promoted to move down by waterpower, the throttling groove area of passage reduces, produces throttling action, source pressure is high more, the distance that spool moves down is big more, the throttling groove area of passage is more little, throttle rate is high more, when center spool axle upper limit boss is pressed on the valve seat boss, the area of passage minimum of throttling groove.When source pressure reduced, spool moved up under the spring force effect, and the area of passage of throttling groove increases.By appropriate design throttling groove and spring, can be implemented in the flow substantially constant that passes through throttling groove in certain source pressure excursion, the pressure in the while downstream line is substantially constant also, realizes saving water and energy.
Figure 2 shows that embodiment two of the present utility model, the screw thread that is connected with pipeline is arranged at valve seat 1 top, and osculum 1-1 is arranged on the lower boss, and spool 2 middle parts are formed with on the cup-shaped cavity, cavity wall of upward opening throttling groove 2-1.Space between cup-shaped cavity, throttling groove, valve seat and the spool, osculum constitute the fluid passage.The working procedure of present embodiment is with embodiment one.
Figure 3 shows that embodiment three of the present utility model, on the lower end surface of spool 2 cup-shaped cavitys aperture is arranged, the aperture water outlet is clashed into mutually with the water outlet of osculum 1-1 can form atomizing or rain flower, is fit to do the shower nozzle series products.All the other are with embodiment two.
Figure 4 shows that embodiment four of the present utility model, there is spacing inward flange the valve seat lower end, has on the spool flange throttling groove 2-1 is arranged on water intake, the central shaft.All the other are with embodiment one.
Figure 5 shows that embodiment five of the present utility model, in the present embodiment, on the spool flange water intake is arranged, on the cup-shaped cavity of oriented under shed, the cavity wall throttling groove 2-1 is arranged on the central shaft.All the other are with embodiment one.
Figure 6 shows that embodiment six of the present utility model, present embodiment is except that the spool water outlet is provided with rectifier 5, and all the other are with embodiment five.Described rectifier comprises spoke shape current stabilizer, swirling flow accelerator, gondola water faucet, atomizer.The most suitable rinser of doing of present embodiment is as medical eyes rinser etc.
